What must be done to delete one or more files from an application when using a partial application update?

1. A. Manually delete the files from the file system (on all nodes if clustered).
2. B. Supply the paths to the files that should be deleted in the administrative console.
3. C. Include a META-INF/ibm-partialapp-delete.props in the partial applicationupdate file.
4. D. Select the files that need to be deleted in the file selector section of the form for the partial application update.

Correct Answer: C
If you want to delete application files when you deploy a partial application update, you must first supply a special metadata file called META-INF/ibm-partialapp-delete.props in the partial application compressed file before you continue with the following procedure. Etc.

An administrator notices that the Message Driven Beans (MDBs) are slow to complete, and decides to increase the ‘Maximum concurrent MDB invocations per endpoint’.
Which thread pool should be tuned to ensure it can run the maximum number of MDBs without waiting?

1. A. Default
2. B. WebContainer
3. C. SIBJMSRAThreadPool
4. D. WMQJCAResourceAdapter

Correct Answer: D
The thread pool WMQJCAResourceAdapter is referenced by the WebSphere MQ (WMQ) resource adapter inbound delivery to MDB's. When WebSphere MQ resource adapter is used in conjunction with the activation specs, the resource adapter's Work Manager uses the values defined for the WMQJCAResourceAdapter for utilizing the total number of threads defined.
Ideally the default values provides for the WMQJCAResourceAdapter will be sufficient for the resource adapter. But in case there is an heavy load on the system processing huge
number of messages, you can increase the maximum number of threads the thread pool can hold.

When deploying a new edition of an application, which edition rollout configuration option should be used to ensure that the two editions of the application are not active at the same
time?

1. A. Atomic
2. B. Grouped
3. C. Soft reset
4. D. Hard reset

Correct Answer: A
Performing an atomic rollout to an edition replaces an edition on half of the cluster at a time to serve all user requests with a consistent edition of the application. All user requests are served by either the previous or the new edition; user requests are never served by both editions.
An atomic rollout ensures that all application requests are served by a consistent edition, for example, either edition 1.0 or 2.0, but not by both.

Which two statements describe a web server in a cell topology?

1. A. Creating a new node for a web server adds a managed node.
2. B. Creating a new node for a web server adds an unmanaged node.
3. C. Adding a web server to an existing node created a managed node.
4. D. Deleting a web server from an unmanaged node creates a managed node.
5. E. Deleting a web server from a managed node creates an unmanaged node.

Correct Answer: AE
A managed node must exist to define a Web server definition, which is always on a managed node.

What determines which On Demand Routers (ODRs) a Web server forwards requests to?

1. A. The default order in theODR_Module_Routing_Poilicy.xml.
2. B. The configuration scope determines which ODRs are included inhttpd.conf.
3. C. The configuration scope determines which ODRs are included inplugin-cfg.xml.
4. D. The configuration scope determines which ODRs are included inHTTPplugin-cfg.xml.

Correct Answer: C
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin- cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.
