A solution implementer is deploying four DataPower XI52 appliances in a production environment. The requirement is to evenly distribute clienttraffic across all four appliances without using an external load balancer. The firmware on these four appliances has the Application Optimization feature enabled. A standby Virtual IP address (VIP) has also been configured on each appliance with self-balancing enabled, and each VIP specifies the same standby group. No other appliance network settings have been changed. What should the solution implementer verify with the network team to ensure that this configuration will work? Ensure the network supports:

• A. gratuitous ARP.
• B. multiple MAC addresses per Ethernet port.
• C. rapid spanning tree.
• D. virtual MAC takeover.

In the Configured Rules section of the Policy Editor, two request rules are listed, Rule_One, followed by Rule_Two, and both use the same matching rule.

What occurs when a message that satisfies the matching rule is received?

• A. Rule_One will be executed, followed by Rule_Two, since all rules that satisfy the match are executed.
• B. The policy will not be applied, since the Policy Editor will not allow a configuration of rules that have the same match.
• C. This policy will fail during execution, since it cannot be determined which rule should be executed.
• D. Only Rule_One will beexecuted since it is the first rule that matches the request.

A solution implementer is considering the following active-standby configuration between two DataPower appliances:

In a simulated power failure of Appliance 1 using this active-standby configuration in a sandbox environment, Appliance 2 did not take over the active interface. What could be causing this behavior?

• A. There might be a firewall between the two appliances which has not been configured to allow broadcast traffic in an active-standby configuration.
• B. It can take several minutes for the standby interfaces to be active in an active-standby configuration.
• C. Appliances in the active-standby configuration must be in the same network subnet and broadcast domain.
• D. In an active-standby configuration, thepriority of Appliance 2 must be changed to 99 for the failure takeover to work.

A solution implementer has been provided the following securityrequirements to implement a solution for a company to transact business with its business partners. ?Message Confidentiality - none can see the message in transit in clear text between the company and partner end points ?Message Integrity - no man-in-the-middle tampered with the message between the company and partner end points ?Non-repudiation - be able to verify the senders are who they say they are What actions should the solution implementer take to satisfy all the requirements?

• A. Use SSL and createa digital signature solution with sign and verify actions.
• B. Use symmetric encryption and share the encryption key with the partner for both request and response.
• C. Use SSL since it satisfies all the requirements without the use of either encrypt/decrypt actionsor sign/verify actions.
• D. Use SSL and create an asymmetric encryption on the message with encrypt and decrypt actions.

A company has exposed aweb service to both internal and external clients. Requests from internal clients are sent in plain text and requests from external clients are encrypted in accordance with the WS-Security specification. A single web service proxy has been created using the WSDL that describes the web service. How can the solution implementer accommodate both the plain text and encrypted requests in the same web service proxy?

• A. Add a Decrypt action to the Default Request Rule, with a Certificate object that is associatedwith the external client's private key.
• B. Create a Crypto Certificate object using the external client's public certificate, create a Crypto Validation Credential (valcred) using the Crypto Certificate object, and add a Decrypt action that uses valcred to the Default Request Rule.
• C. Provide the company's public certificate to the external client for use in encryption, create a Crypto Key object that points to the company private key, and set the Decrypt Key at the proxy level.
• D. Provide thecompany's public certificate to the external client for use in encryption, create a Crypto Key object that points to the company's public certificate, and use it to add a Decrypt action to the Default Request Rule.
