NEW QUESTION # 12
An interface is configured with a behavior aggregate classifier and a multifield classifier How will the packet be processed when received on this interface?
- A. The packet will be forwarded with no classification changes.
- B. The packet will be processed by the BA classifier first, then the MF classifier.
- C. The packet will be processed by the MF classifier first, then the BA classifier.
- D. The packet will be discarded.
Answer: A
Explanation:
Explanation
behavior aggregate (BA) classifiers and multifield (MF) classifiers are two types of classifiers that are used to assign packets to a forwarding class and a loss priority based on different criteria. The forwarding class determines the output queue for a packet. The loss priority is used by a scheduler to control packet discard during periods of congestion.
A BA classifier maps packets to a forwarding class and a loss priority based on a fixed-length field in the packet header, such as DSCP, IP precedence, MPLS EXP, or IEEE 802.1p CoS bits. A BA classifier is computationally efficient and suitable for core devices that handle high traffic volumes. A BA classifier is useful if the traffic comes from a trusted source and the CoS value in the packet header is trusted.
An MF classifier maps packets to a forwarding class and a loss priority based on multiple fields in the packet header, such as source address, destination address, protocol type, port number, or VLAN ID. An MF classifier is more flexible and granular than a BA classifier and can match packets based on complex filter rules. An MF classifier is suitable for edge devices that need to classify traffic from untrusted sources or rewrite packet headers.
You can configure both a BA classifier and an MF classifier on an interface. If you do this, the BA classification is performed first and then the MF classification. If the two classification results conflict, the MF classification result overrides the BA classification result.
Based on this information, we can infer the following statements:
* The packet will be discarded. This is not correct because the packet will not be discarded by the classifiers unless it matches a filter rule that specifies discard as an action. The classifiers only assign packets to a forwarding class and a loss priority based on their match criteria.
* The packet will be processed by the BA classifier first, then the MF classifier. This is correct because if both a BA classifier and an MF classifier are configured on an interface, the BA classification is performed first and then the MF classification. If they conflict, the MF classification result overrides the BA classification result.
* The packet will be forwarded with no classification changes. This is not correct because the packet will be classified by both the BA classifier and the MF classifier if they are configured on an interface. The final classification result will determine which output queue and which discard policy will be applied to the packet.
* The packet will be processed by the MF classifier first, then the BA classifier. This is not correct because if both a BA classifier and an MF classifier are configured on an interface, the BA classification is performed first and then the MF classification. If they conflict, the MF classification result overrides the BA classification result.
NEW QUESTION # 13
Which two statements are correct about the customer interface in an LDP-signaled pseudowire? (Choose two)
- A. When the encapsulation is vLan-ccc or extended-vlan-ccc, the configured VLAN tag is included in the control plane LDP advertisement
- B. When the encapsulation is ethemet-ccc, tagged and untagged frames are both accepted in the data plane.
- C. When the encapsulation is vlan-ccc or extended-vlan-ccc, the configured VLAN tag is not included in the control plane LDP advertisement
- D. When the encapsulation is ethernet-ccc, only frames without a VLAN tag are accepted in the data plane
Answer: A,B
Explanation:
Explanation
The customer interface in an LDP-signaled pseudowire is the interface on the PE router that connects to the CE device. An LDP-signaled pseudowire is a type of Layer 2 circuit that uses LDP to establish a point-to-point connection between two PE routers over an MPLS network. The customer interface can have different encapsulation types depending on the type of traffic that is carried over the pseudowire. The encapsulation types are ethernet-ccc, vlan-ccc, extended-vlan-ccc, atm-ccc, frame-relay-ccc, ppp-ccc, cisco-hdlc-ccc, and tcc-ccc. Depending on the encapsulation type, the customer interface can accept or reject tagged or untagged frames in the data plane, and include or exclude VLAN tags in the control plane LDP advertisement. The following table summarizes the behavior of different encapsulation types:
NEW QUESTION # 14
Exhibit
Which two statements about the configuration shown in the exhibit are correct? (Choose two.)
- A. This VPN connects customer sites that use different AS numbers.
- B. A Layer 2 VPN is configured.
- C. A Layer 3 VPN is configured.
- D. This VPN connects customer sites that use the same AS number
Answer: A,C
Explanation:
Explanation
The configuration shown in the exhibit is for a Layer 3 VPN that connects customer sites that use different AS numbers. A Layer 3 VPN is a type of VPN that uses MPLS labels to forward packets across a provider network and BGP to exchange routing information between PE routers and CE routers. A Layer 3 VPN allows customers to use different routing protocols and AS numbers at their sites, as long as they can peer with BGP at the PE-CE interface. In this example, CE-1 is using AS 65530 and CE-2 is using AS 65531, but they can still communicate through the VPN because they have BGP sessions with PE-1 and PE-2, respectively.
NEW QUESTION # 15
In which two ways does OSPF prevent routing loops in multi-area networks? (Choose two.)
- A. The LFA algorithm prunes all looped paths within an area.
- B. The SPF algorithm prunes looped paths within an area.
- C. All areas are required to connect to area 0.
- D. All areas are required to connect as a full mesh.
Answer: B,C
Explanation:
Explanation
OSPF is an interior gateway protocol that uses link-state routing to exchange routing information among routers within a single autonomous system. OSPF prevents routing loops in multi-area networks by using two methods: area hierarchy and SPF algorithm. Area hierarchy is the concept of dividing a large OSPF network into smaller areas that are connected to a backbone area (area 0). This reduces the amount of routing information that each router has to store and process, and also limits the scope of link-state updates within each area. All areas are required to connect to area 0 either directly or through virtual links2. SPF algorithm is the method that OSPF uses to calculate the shortest path to each destination in the network based on link-state information. The SPF algorithm runs on each router and builds a shortest-path tree that represents the topology of the network from the router's perspective. The SPF algorithm prunes looped paths within an area by choosing only one best path for each destination3.

NEW QUESTION # 16
Exhibit
You are asked to exchange routes between R1 and R4 as shown in the exhibit. These two routers use the same AS number Which two steps will accomplish this task? (Choose two.)
- A. Configure the BGP group with the as-override parameter on R1 and R4
- B. Configure the BGP group with the advertise-peer-as parameter on R1 and R4.
- C. Configure the BGP group with the advertise-peer-as parameter on R2 and R3.
- D. Configure the BGP group with the as-override parameter on R2 and R3
Answer: B,D
Explanation:
Explanation
The advertise-peer-as parameter allows a router to advertise its peer's AS number as part of the AS path attribute when sending BGP updates to other peers. This parameter is useful when two routers in the same AS need to exchange routes through another AS, such as in the case of R1 and R4. By configuring this parameter on R1 and R4, they can advertise each other's AS number to R2 and R3, respectively.
The as-override parameter allows a router to replace the AS number of its peer with its own AS number when receiving BGP updates from that peer. This parameter is useful when two routers in different ASes need to exchange routes through another AS that has the same AS number as one of them, such as in the case of R2 and R3. By configuring this parameter on R2 and R3, they can override the AS number of R1 and R4 with their own AS number when sending BGP updates to each other.
NEW QUESTION # 17
Exhibit
Referring to the exhibit, PE-1 and PE-2 are getting route updates for VPN-B when neither of them service that VPN Which two actions would optimize this process? (Choose two.)
- A. Configure the family route-target statement on the RR
- B. Configure the family route-target statement on the PEs.
- C. Configure the resolution rib bgp . 13vpn . 0 resolution-ribs inet. 0 Statement on the PEs.
- D. Configure the resolution rib bgp.l3vpn.O resolution-ribs inet. 0 Statement on the RR
Answer: A,D
Explanation:
Explanation
BGP route target filtering is a technique that reduces the number of routers that receive VPN routes and route updates, helping to limit the amount of overhead associated with running a VPN. BGP route target filtering is based on the exchange of the route-target address family, which contains information about the VPN membership of each PE device. Based on this information, a PE device can decide whether to accept or reject VPN routes from another PE device.
BGP route target filtering can be configured on PE devices or on route reflectors (RRs). Configuring BGP route target filtering on RRs is more efficient and scalable, as it reduces the number of BGP sessions and updates between PE devices. To configure BGP route target filtering on RRs, the following steps are required:
* Configure the family route-target statement under the BGP group or neighbor configuration on the RRs.
This enables the exchange of the route-target address family between the RRs and their clients (PE devices).
* Configure the resolution rib bgp.l3vpn.0 resolution-ribs inet.0 statement under the routing-options configuration on the RRs. This enables the RRs to resolve next hops for VPN routes using the inet.0 routing table.
* Configure an export policy for BGP route target filtering under the routing-options configuration on the RRs. This policy controls which route targets are advertised to each PE device based on their VPN membership.
NEW QUESTION # 18
Which statement is true regarding BGP FlowSpec?
- A. It verifies that the source IP of the incoming packet has a resolvable route in the routing table
- B. It uses dynamically created routing policies to protect a network from denial-of-service attacks
- C. It uses a remote triggered black hole to protect a network from a denial-of-service attack.
- D. It is used to protect a network from denial-of-service attacks dynamically
Answer: B
Explanation:
Explanation
BGP FlowSpec is a feature that extends the Border Gateway Protocol (BGP) to enable routers to exchange traffic flow specifications, allowing for more precise control of network traffic. The BGP FlowSpec feature enables routers to advertise and receive information about specific flows in the network, such as those originating from a particular source or destined for a particular destination. Routers can then use this information to construct traffic filters that allow or deny packets of a certain type, rate limit flows, or perform other actions1. BGP FlowSpec can also help in filtering traffic and taking action against distributed denial of service (DDoS) attacks by dropping the DDoS traffic or diverting it to an analyzer2. BGP FlowSpec rules are internally converted to equivalent Cisco Common Classification Policy Language (C3PL) representing corresponding match and action parameters2. Therefore, BGP FlowSpec uses dynamically created routing policies to protect a network from denial-of-service attacks.

NEW QUESTION # 19
Which two statements describe PIM-SM? (Choose two)
- A. Traffic is initially flooded to all routers and an S,G is maintained for each group
- B. Traffic is only forwarded to routers that request to join the distribution tree.
- C. Routers with receivers send join messages to their upstream neighbors.
- D. Routers without receivers must periodically prune themselves from the SPT.
Answer: B,C
Explanation:
Explanation
PIM sparse mode (PIM-SM) is a multicast routing protocol that uses a pull model to deliver multicast traffic.
In PIM-SM, routers with receivers send join messages to their upstream neighbors toward a rendezvous point (RP) or a source-specific tree (SPT). The RP or SPT acts as the root of a shared distribution tree for a multicast group. Traffic is only forwarded to routers that request to join the distribution tree by sending join messages.
PIM-SM does not flood traffic to all routers or prune routers without receivers, as PIM dense mode does.
NEW QUESTION # 20
Exhibit
Referring to the exhibit, which two statements are true? (Choose two.)
- A. The device advertising this route into EVPN is 192.168.101.5.
- B. This is an EVPN Type-2 route.
- C. This route is learned through EBGP
- D. The devices advertising this route into EVPN are 10 0 2 12 and 10.0.2.22.
Answer: A,B
Explanation:
Explanation
This is an EVPN Type-2 route, also called a MAC/IP advertisement route, that is used to advertise host IP and MAC address information to other VTEPs in an EVPN network. The route type field in the EVPN NLRI has a value of 2, indicating a Type-2 route. The device advertising this route into EVPN is 192.168.101.5, which is the IP address of the VTEP that learned the host information from the local CE device. This IP address is carried in the MPLS label field of the route as part of the VXLAN encapsulation.
NEW QUESTION # 21
Which two statements are correct regarding bootstrap messages that are forwarded within a PIM sparse mode domain? (Choose two.)
- A. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain.
- B. Bootstrap messages are forwarded only to routers that explicitly requested the messages within the PIM sparse-mode domain
- C. Bootstrap messages distribute RP information dynamically during an RP election.
- D. Bootstrap messages are used to notify which router is the PIM RP
Answer: A,C
Explanation:
Explanation
Bootstrap messages are PIM messages that are used to distribute rendezvous point (RP) information dynamically during an RP election. Bootstrap messages are sent by bootstrap routers (BSRs), which are routers that are elected to perform the RP discovery function for a PIM sparse-mode domain. Bootstrap messages contain information about candidate RPs and their multicast groups, as well as BSR priority and hash mask length. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain using hop-by-hop flooding.
NEW QUESTION # 22
Which two statements are correct about VPLS tunnels? (Choose two.)
- A. BGP-signaled VPLS tunnels require manual provisioning of sites.
- B. LDP-signaled VPLS tunnels only support control bit 0.
- C. BGP-signaled VPLS tunnels can use either RSVP or LDP between the PE routers.
- D. LDP-signaled VPLS tunnels use auto-discovery to provision sites
Answer: C,D
Explanation:
Explanation
VPLS is a Layer 2 VPN technology that allows multiple sites to connect over a shared IP/MPLS network as if they were on the same LAN. VPLS tunnels can be signaled using either Label Distribution Protocol (LDP) or Border Gateway Protocol (BGP). LDP-signaled VPLS tunnels use auto-discovery to provision sites, meaning that PE routers can automatically discover other PE routers that belong to the same VPLS instance
NEW QUESTION # 23
Exhibit
You are running a service provider network and must transport a customer's IPv6 traffic across your IPv4-based MPLS network using BGP You have already configured mpis ipv6-tunneling on your PE routers.
Which two statements are correct about the BGP configuration in this scenario? (Choose two.)
- A. You must configure family inet6 unicaat between PE and CE routers.
- B. You must configure family inet6 unicast between PE routers
- C. You must configure family inet6 labcled-unicast between PE routers.
- D. You must configure family inet6 add-path between PE and CE routers.
Answer: A,C
Explanation:
Explanation
To transport IPv6 traffic over an IPv4-based MPLS network using BGP, you need to configure two address families: family inet6 labeled-unicast and family inet6 unicast. The former is used to exchange IPv6 routes with MPLS labels between PE routers, and the latter is used to exchange IPv6 routes without labels between PE and CE routers. The mpis ipv6-tunneling command enables the PE routers to encapsulate the IPv6 packets with an MPLS label stack and an IPv4 header before sending them over the MPLS network.
NEW QUESTION # 24
Exhibit
You want Site 1 to access three VLANs that are located in Site 2 and Site 3 The customer-facing interface on the PE-1 router is configured for Ethernet-VLAN encapsulation.
What is the minimum number of L2VPN routing instances to be configured to accomplish this task?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Explanation
To allow Site 1 to access three VLANs that are located in Site 2 and Site 3, you need to configure three L2VPN routing instances on PE-1, one for each VLAN. Each L2VPN routing instance will have a different VLAN ID and a different VNI for VXLAN encapsulation. Each L2VPN routing instance will also have a different vrf-target export value to identify which VPN routes belong to which VLAN. This way, PE-1 can forward traffic from Site 1 to Site 2 and Site 3 based on the VLAN tags and VNIs.
NEW QUESTION # 25
Exhibit
You are examining an L3VPN route that includes the information shown in the exhibit Which statement is correct in this scenario?
- A. The information shows a Type 2 route distinguisher.
- B. The information shows a route target
- C. The information shows a Type 0 route distinguisher
- D. The information shows a Type 1 route distinguisher.
Answer: C
Explanation:
Explanation
The information shows a Type 0 route distinguisher, which is one of the three types of route distinguishers defined by RFC 4364. A route distinguisher is a 64-bit value that is prepended to an IPv4 address to create a VPN-IPv4 address, which is unique within a VPN routing and forwarding (VRF) table. A Type 0 route distinguisher has two fields: an administrator subfield (2 bytes) and an assigned number subfield (6 bytes). The administrator subfield can be an AS number or an IP address, and the assigned number subfield can be any value assigned by the administrator. In this example, the administrator subfield is 65530 (an AS number) and the assigned number subfield is 1.
NEW QUESTION # 26
Exhibit
Referring to the exhibit, CE-1 is providing NAT services for the hosts at Site 1 and you must provide Internet access for those hosts Which two statements are correct in this scenario? (Choose two.)
- A. You must configure a static route in the main routing instance for the 203.0.113.1/32 prefix that uses the VPN-A.inet.0 table as the next hop.
- B. You must configure a RIB group on PE-1 to leak a default route from the inet.0 table to the VPN-A.inet.0 table.
- C. You must configure a static route in the main routing instance for the 10 1 2.0/24 prefix that uses the VPN-A.inet.0 table as the next hop
- D. You must configure a RIB group on PE-1 to leak the 10 1 2.0/24 prefix from the VPN-A.inet.0 table to the inet.0 table.
Answer: A,C
Explanation:
Explanation
To provide Internet access for the hosts at Site 1, you need to configure static routes in the main routing instance on PE-1 that point to the VPN-A.inet.0 table as the next hop. This allows PE-1 to forward traffic from the Internet to CE-1 using MPLS labels and vice versa. You need to configure two static routes: one for the
10.1.2.0/24 prefix that represents the private network of Site 1, and one for the 203.0.113.1/32 prefix that represents the public IP address of CE-1.
NEW QUESTION # 27
Exhibit.
Referring to the exhib.t, what must be changed to establish a Level 1 adjacency between routers R1 and R2?
- A. Add IP addresses to the interface ge-l/2/3 unit 0 family iso hierarchy on both R1 and R2.
- B. Change the level 1 disable parameter under the R2 protocols isis interface ge-1/2/3 .0 hierarchy to the level 2 disable parameter
- C. Remove the level i disable parameter under the R2 protocols isis interface loo . 0 configuration hierarchy.
- D. Change the level l disable parameter under the R1 protocols isis interface lo0.0 hierarchy to the level 2 disable parameter.
Answer: C
Explanation:
Explanation
IS-IS routers can form Level 1 or Level 2 adjacencies depending on their configuration and network topology.
Level 1 routers are intra-area routers that share the same area address with their neighbors. Level 2 routers are inter-area routers that can connect different areas. Level 1-2 routers are both intra-area and inter-area routers that can form adjacencies with any other router.
In the exhibit, R1 and R2 are in different areas (49.0001 and 49.0002), so they cannot form a Level 1 adjacency. However, they can form a Level 2 adjacency if they are both configured as Level 1-2 routers. R1 is already configured as a Level 1-2 router, but R2 is configured as a Level 1 router only, because of the level 1 disable command under the lo0.0 interface. This command disables Level 2 routing on the loopback interface, which is used as the router ID for IS-IS.
Therefore, to establish a Level 1 adjacency between R1 and R2, the level 1 disable command under the R2 protocols isis interface lo0.0 hierarchy must be removed. This will enable Level 2 routing on R2 and allow it to form a Level 2 adjacency with R1.
NEW QUESTION # 28
By default, which statement is correct about OSPF summary LSAs?
- A. The metric associated with a summary route will be equal to the lowest metric associated with an individual contributing route
- B. All Type 2 and Type 7 LSAs will be summanzed into a single Type 5 LSA
- C. Type 3 LSAs are advertised for routes in Type 1 LSAs.
- D. The area-range command must be installed on all routers.
Answer: C
Explanation:
Explanation
OSPF uses different types of LSAs to describe different aspects of the network topology. Type 1 LSAs are also known as router LSAs, and they describe the links and interfaces of a router within an area. Type 3 LSAs are also known as summary LSAs, and they describe routes to networks outside an area but within the same autonomous system (AS). By default, OSPF will summarize routes from Type 1 LSAs into Type 3 LSAs when advertising them across area boundaries .
NEW QUESTION # 29
Exhibit
Which two statements are true about the OSPF adjacency displayed in the exhibit? (Choose two.)
- A. There is a mismatch in the dead interval parameter between routers R1 and R2.
- B. There is a mismatch in the hello interval parameter between routers R1 and R2
- C. There is a mismatch in the OSPF hold timer parameter between routers R1 and R2.
- D. There is a mismatch in the poll interval parameter between routers R1 and R2.
Answer: A,B
Explanation:
Explanation
The hello interval is the time interval between two consecutive hello packets sent by an OSPF router on an interface. The dead interval is the time interval after which a neighbor is declared down if no hello packets are received from it. These parameters must match between two OSPF routers for them to form an adjacency. In the exhibit, router R1 has a hello interval of 10 seconds and a dead interval of 40 seconds, while router R2 has a hello interval of 30 seconds and a dead interval of 120 seconds. This causes a mismatch and prevents them from becoming neighbors23.
NEW QUESTION # 30
You are asked to protect your company's customers from amplification attacks. In this scenario, what is Juniper's recommended protection method?
- A. ASN prepending
- B. unicast Reverse Path Forwarding
- C. BGP FlowSpec
- D. destination-based Remote Triggered Black Hole
Answer: D
Explanation:
Explanation
amplification attacks are a type of distributed denial-of-service (DDoS) attack that exploit the characteristics of certain protocols to amplify the traffic sent to a victim. For example, an attacker can send a small DNS query with a spoofed source IP address to a DNS server, which will reply with a much larger response to the victim. This way, the attacker can generate a large amount of traffic with minimal resources.
One of the methods to protect against amplification attacks is destination-based Remote Triggered Black Hole (RTBH) filtering. This technique allows a network operator to drop traffic destined to a specific IP address or prefix at the edge of the network, thus preventing it from reaching the victim and consuming bandwidth and resources. RTBH filtering can be implemented using BGP to propagate a special route with a next hop of
192.0.2.1 (a reserved address) to the edge routers. Any traffic matching this route will be discarded by the edge routers.
NEW QUESTION # 31
When building an interprovider VPN, you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unica3t configured.
Which parameter must you configure to solve this problem?
- A. Under the protocols ospf hierarchy, add the traffic-engineering parameter.
- B. Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
- C. Under the protocols mpls hierarchy, add the traffic-engineering parameter
- D. Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
Answer: D
Explanation:
Explanation
The resolve-vpn parameter is a BGP option that allows a router to resolve labeled VPN-IPv4 routes using unlabeled IPv4 routes received from another BGP peer with family inet labeled-unicast configured. This option enables interprovider VPNs without requiring MPLS labels between ASBRs or using VRF tables on ASBRs. In this scenario, you need to configure the resolve-vpn parameter under [edit protocols bgp group external family inet labeled-unicast] hierarchy level on both ASBRs.
NEW QUESTION # 32
Which two statements are correct about reflecting inet-vpn unicast prefixes in BGP route reflection? (Choose two.)
- A. Route reflectors do not change any existing BGP attributes by default when advertising routes.
- B. Clients add their originator ID when advertising routes to their route reflector
- C. A BGP peer does not require any configuration changes to become a route reflector client.
- D. Route reflectors add their cluster ID to the AS path when readvertising client routes.
Answer: A,C
Explanation:
Explanation
Route reflection is a BGP feature that allows a router to reflect routes learned from one IBGP peer to another IBGP peer, without requiring a full-mesh IBGP topology. Route reflectors do not change any existing BGP attributes by default when advertising routes, unless explicitly configured to do so. A BGP peer does not require any configuration changes to become a route reflector client, only the route reflector needs to be configured with the client parameter under [edit protocols bgp group group-name neighbor neighbor-address] hierarchy level.
