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) There is no network load balancer used behind DataPower. Install a network load balancer.
B) The backend system may be rejecting all TCP packets. Apply the latest fixpacks and restart the server.
C) 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.
D) 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.

2. A solution implementer needs to configure a front side handler in a multi-protocol gateway service thatonly accepts messages from applications servers that are in the 10.10.10.0/24 subnet. What can the solution implementer configure in a front side handler to restrict messages to the 10.10.10.0/24 subnet?

A) Specify a Port Number to a value in the ephemeral port range
B) Specify a SSL Proxy Profile that requires a client side certificate signed by a trusted certificate authority
C) Specify an Access Control List with an entry of "allow 10.10.10.0/24"
D) Specify a Local IP Address of 10.10.10.0/24

3. An organization has isolated environments for development, functional, integration and performance testing. Each environment includes at least one DataPower appliance, client, and several instances of backend systems. A solution implementer has made changes to a DataPower service in the development environment that needs to be promoted to other testenvironments for further testing. During migration, environment specific values must be changed in order for the configuration to integrate with the correct backend systems in the target environment. What options does the solution implementer have to automate this migration? (choose three)

A) Use the WebGUI to change environment specific values and then export the configuration.
B) Use an external script to search and replace environment values. Then use the script to push the configuration via CLI or XML Management Interface.
C) Use the Deployment Policy object to changeenvironment specific values at the time of export at the source appliance.
D) Use the Deployment Policy object to change environment specific values at the time of import at the target appliance.
E) Take a secure backup of the appliance and secure restore the configuration on the target appliance.
F) Use the checkpoint function of the appliance to save copies of configuration for specific target environments.

4. The solution implementer configured a multi-protocol gateway (MPGW) service to process WebSphere MQ messages using the same MQ queue manager object for both the front
end and back end. A request rule in the processing policy sends a message to queue A and then to queue B in a single transaction by using a "Result Action". The MQ URL forthe back end contains the "Transactional=true" tag. The output type of the "Result Actions" is set as "Binary" and the OUTPUT context has a named variable. What are the additional configuration options that the solution implementer needs to guarantee message delivery for both back-end queues? Specifically, if any one message fails, the entire transaction will roll back.

A) Configure "Units of Work = 1" and "Automatic Backout = off "in the MQ queue manager object.
B) Configure two phase commit in the backend WebSphere MQ queue manager.
C) DataPower cannot support this use case as an MQ queue manager object only works with global transactionality.
D) Configure "Units of Work = 1" and "Automatic Backout = on"; "Backout Threshold" and "Backout Queue" defined in the MQ queue manager object.

5. A company has an extensive list of Miscellaneous XML Threats that they require protection from. The list includes: ?XML Entity Expansion and RecursionAttacks ?XML Wellformedness-based Parser Attacks ?Memory Space Breach and Buffer Overflow Attacks ?Public Key DoS Attacks ?Resource Hijack Attacks What must the solution implementer do to protect SOA Applications exposed via a WSDL and a Web Service Proxyservice?

A) Enable the web service proxy's ingle Message XML Denial of Service (XDoS) Protection".Enable the web service proxy's ?ingle Message XML Denial of Service (XDoS) Protection".
B) Enable the web service proxy's QL Injection Protection?Enable the web service proxy's ?QL Injection Protection?
C) Enable the web service proxy's ultiple Message XML Denial of Service (MMXDoS) Protection".Enable the web service proxy's ?ultiple Message XML Denial of Service (MMXDoS) Protection".
D) Web service proxy default options protect against these threats. No configuration is required.
