IBM WebSphere DataPower SOA Appliances Firmware V5.0 Solution Implementation Sample Questions:

1. An operations team is reporting intermittent network connectivity problems between DataPower and a specific backend IP address. Network firewalls are configured to allow traffic and thereare no known problems on the network. How can the solution implementer troubleshoot this behavior?

A) The backend system may be rejecting all TCP packets. Apply the latest fixpacks and restart the server.
B) Conflicting network routes in the appliance may have been defined which may be causing intermittent network connections. Run "show route" command on the network and analyze the configuration.
C) There is no network load balancer used behind DataPower. Install a network load balancer.
D) A DNS host name may be used for connecting to the backend system. Intermittent errors could be caused due to the DNS names not being resolved. Use a host alias instead.

2. A solution implementer needs to configure the appliance to throttle transactions if the device memory utilization reaches 70%. What can the solution implementer do to achieve the desired result?

A) Configure Throttle Settings and set the Memory Throttle threshold to 30%.
B) Configure the Statistic Settings with load interval of 1 and memory threshold to 30%.
C) Memory management is an internal DataPower function and cannot be configured.
D) Configure an SLM action to throttle transactions when memory reaches 70%.

3. A solution implementer needs to add custom headers required by the back-end system to all request messages. A stylesheet based Transform action is used to add the necessary headers. Which DataPower capabilities can the solution implementer use to verify that the requiredheaders have been added properly? (choose 2)

A) <xsl:message> to print the header values to the system log file and checkthe system log file during testing.
B) The Headers tab in the service to view the Header Injection parameters.
C) The multi-step probe to check the values in the Headers tab before and after the Transform action.
D) <xsl:message> to print the header values to the audit log file and check the audit log file during testing.
E) Debug logging at the backendservice to confirm that the necessary header values have been added.

4. A company-wide Certificate Authority (CA) provides its internal CA root and intermediary certificates to the solution implementer to use for the creation of Validation Credentials that validates several back end servers using SSL. The two lines of business in the company provide services on two different domains on DataPower and two different banks of servers on the back end. The requirement is to share a single copy of the CA certificates to create validation credentials in two domains for both the lines of business to simplify maintenance. How can the solution implementer satisfy the requirement?

A) Store the CA certificates in the sharedcert: folder from the default domain.
B) Store the CA certificates in the store:///cert folder from the default domain.
C) Store the certificatein the cert: folder in any of the two domains and mark the certificate as shared.
D) Create Validation Credentials in the default domain so it can be shared across all the domains.

5. A company wants to implement disaster recovery (DR) between a9004/9235 appliance and a 9005/7199 appliance. The company is also considering the inclusion of a DR-enabled XI52 virtual appliance in the plan. The following conditions apply: ?The source and target hardware appliances are located in geographically dispersed data centers. ?The firmware level is V5.0.0.x on the appliances, and the appliances and licenses are compatible. ?Both appliances have a different set of users that need to be merged on the restore. ?The source appliance has been initialized with disaster recovery mode and is to be securely backed up and restored on to the target appliance. Which one of the following statements is TRUE and allows the solution implementer to meet these conditions?

A) The secure backup from the 9005 physical appliance can be restored on the virtual appliance since they are both 9005 implementations.
B) After the secure restore, the users that were defined on the target appliance must be manually configured or imported from a previously-exported configuration.
C) Only the source appliance must be set to disaster recovery mode for the secure restore to be successful.
D) Merge the contents of the source appliance with the target appliance by NOT selecting the "overwrite" option when prompted, which will merge the users on the target appliance.
