IBM WebSphere DataPower SOA Appliances Firmware V5.0 Solution Implementation

Question 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. 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.

B. There is no network load balancer used behind DataPower. Install a network load balancer.

C. The backend system may be rejecting all TCP packets. Apply the latest fixpacks and restart the server.

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.

Correct Answer: A

Question 2

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. transform() extension function

B. <xsl:include ..> statement to include it dynamically at run time if the file exists

C. evaluate() extension function

D. pre-processing() extension function

Correct Answer: A

Question 3

A solution implementer is tasked to use a DataPower appliance as an intermediary for providing Web 2.0 services. Which of the following features of Web 2.0 messages should the solution implementer be aware of when designing thesolution? (choose two)

A. Web 2.0 use cases are best suited for a web service proxy service.

B. Web 2.0 REST messages can use HTTP POST methods like SOAP messages.

C. Web 2.0 messages can arrive with an empty body.

D. Web 2.0 messages can be secured by WS-Security.

E. Web 2.0 message and a SOAP message cannot be processed by the same processing policy and front side handler of a DataPower Service.

Correct Answer: B,C

Question 4

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. 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.

B. 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.

C. Add a Decrypt action to the Default Request Rule, with a Certificate object that is associatedwith the external client's private key.

D. 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.

Correct Answer: D

Question 5

A company wants to inform the consumers of their services whether the DataPowerprocessing failed in the request or the response. They prefer to have generic error handling shared by all their rules and thus have not defined any on-error actions on individual rules. From the default error rule configured, the requirement is to informthe consumer whether the processing policy failed in the request or the response. What extension function should the solution implementer use to implement the requirement?

A. requesting()

B. accepting()

C. catch(rule-id)

D. responding()

Correct Answer: D

Question 6

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. Service (Scope: Single transaction) Local (Scope: Spans repeated transactions)

B. Context (Scope: Singletransaction) Service (Scope: Multiple transactions)

C. Service (Scope: Single transaction) System (Scope: Spans repeated transactions)

D. Context (Scope: Single processing rule) Error (Scope: Single processing rule)

Correct Answer: C

Question 7

A solution implementer needs to create a new service on a DataPower virtual appliance. The new server needs to virtualize the back end server IP address from the end user while exposing operations of a web service described by a given WSDL. Service Level Monitoring (SLM) is also to be incorporated at the port level. Which service type should the solution implementer configure?

A. XML Firewall

B. Web ServiceProxy

C. Web Application Firewall

D. Multi-Protocol Gateway

Correct Answer: B

Question 8

A solution implementer is writing a stylesheet that accepts input as shown in the followingexhibit:

Given the information in the exhibit, which XPath expression locates the element named Pay:payload?

A. /pay:payload/pay:payload

B. //*/Customer/..//*/Customer/..

C. /msg:message/*/msg:message/*

D. /msg:message/..//*/payload/msg:message/..//*/payload

Correct Answer: B
