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

1. A bank wants to be able to dynamically change the behavior of its DataPower mediations for certain services after they have been deployed to production to quickly respond to minor changes in back end services. Towards this purpose, the solution implementer configured rules with a transform action that will dynamically run pre-tested style sheets. What should the solution implementer use to satisfy this requirement?

A) evaluate() extension function
B) transform() extension function
C) pre-processing() extension function
D) <xsl:include ..> statement to include it dynamically at run time if the file exists

2. A DataPower Processing Policy has been coded to use DataPower variables.
To analyze an error in one of the Rules, a solution implementer has enabled the Probe to review message content and DataPower variables. Given the data in the Probe, which one of the following shows the correct variable and scope?

A) Context (Scope: Single processing rule) Error (Scope: Single processing rule)
B) Service (Scope: Single transaction) Local (Scope: Spans repeated transactions)
C) Context (Scope: Singletransaction) Service (Scope: Multiple transactions)
D) Service (Scope: Single transaction) System (Scope: Spans repeated transactions)

3. The solution implementer needs to configure the DataPower appliance to restrict user account access to specific domains. The solution implementer implements this requirement by configuring the Domain Restriction section of the user account. During application execution, the configured user account is able to access a domain that is configured as restricted (no access allowed by this user). What should the solution implementer identify as a valid source of the problem?

A) The RBM system was not used to restrict access, which is the only way to meet the Domain Restriction requirement.
B) User access cannot be restricted to a specific domain in the user account configuration.
C) An existing access policy or RBM policy can supersede the Domain Restriction list.
D) The user is a member of the 'root' user group.

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

5. A customer needs message privacy and message integrity on a given transaction, and prefers the use of WS-Policy. WebSphere DataPower must receive a username from each user, but no authentication is required. In order to implement this without additional custom work, the solution implementer can:

A) use an Encrypt and SignAction in the request, followed by a Decrypt and Verify Action in the response.
B) use WS-Policy with Encryption, Signature and pass the username in the message body.
C) use WS-Policy with UsernameToken, Encryption and Signature enforced.
D) use a basic authentication header, then use the default encryption and signature inherent in the WS-Proxy.
