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

1. Message traffic from a customer purchasing system is passing SOAP messages through a DataPower XI52 appliance. A solution implementer uses a multi-protocol gateway to implement WS-Security to encrypt the complete message. Which of the following parameters should the solution implementer select to correctly configure the Encrypt action?

A) Envelop Method: WSSec encryption Message Type: SOAP Message Document Crypto Map : None
B) Envelop Method: Standard XML encryption Message Type : SOAP Message Document Crypto Map : store:///encrypt_message.xsl
C) Envelop Method: WS-Security Message Type : SOAP Message Document Crypto Map : store:///encrypt_message.xsl
D) Envelop Method: Advanced Message Type : Raw XML document Document Crypto Map : store:///ws_security_encrypt.xsl

2. A web service proxy is receiving orders from partners as SOAP messages. The service is required to reject messages if the total order cost in themessage does not match the sum of the individual item costs. What can the solution implementer do to support this requirement?

A) Create an XML Schema that enforces the above business requirements and uses this schema in a Validate action.
B) Create a style sheet which performs the mathematical comparison and uses either a <dp:accept> or <dp:reject>, and use this in a Filter action.
C) Define the requirement in a WS-Policy attachment for the service. The web service proxy will then automatically perform the mathematical comparison and reject any invalid messages.
D) Configure an SLM Statement with the Threshold Level that computes the total order cost, and if it does not match the totalvalue then throttle the transaction.

3. 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) responding()
B) requesting()
C) accepting()
D) catch(rule-id)

4. A solution implementer is configuring a single multi-protocol gateway to dynamically route messages to back end servers. For internal consumers the request needs to be routed to an MQ based back end and for external consumersthe request needs to be routed to an HTTP based back end service. How can the solution implementer satisfy this requirement?

A) Use the xset-target extension function.
B) Set the variables var://service/URI for the server and var://service/protocol-method for the protocol type.
C) Set the variable var://service/routing-url.
D) Select a route action with an XPath routing map.

5. The solution implementer is testing a new service and finds that the client is receiving a soap fault response during the test.
The default-log shows the following:

What conclusion can the solution implementer determine by analyzing and interpreting the above log?

A) Parsing of the URL began and too much memory was used when the request started.
B) The connection did not reuse a persistent connection and triggered a parse error on the response.
C) Parsing began on the message and failed due to mismatched XML tag.
D) The connection was terminated due to a client IP address parsing problem.
