The computer where a federated node was running had a failure and cannot be recovered. A system administrator wants to recreate the node with the same configurations in another computer.
Which steps should the administrator execute in order to recover the damaged node?

1. A. Configure the new computer with a different hostname.Create a custom profile with the same name.Federate to the cell using the command addNode with the default options.
2. B. Configure the new computer with a different hostname.Create a custom profile with a different name.Federate to the cell using the command addNote with the option–asExistingNode.
3. C. Configure the new computer with the same hostname.Create a custom profile with the same name.Federate to the cell using the command addNote with the option–asExistingNode.
4. D. Configure the new computer with the same hostname.Create a custom profile with the same name.Federate to the cell using the command addNote with the options–includeapps.

Correct Answer: C
You can use the -asExistingNode option of the addNode command to recover and move nodes of a deployment manager. Using the -asExistingNode option, federate a new custom node to a deployment manager as an existing node. During federation, the product uses information in the deployment manager master configuration to transform the custom node into the existing node.

A system administrator has started a Liberty profile server using the default values. Later,
the administrator modified the server.xml file for the server to include

The administrator placed the application ServletApp.war in the apps directory under
${server.config.dir}. While accessing the correct URL for the home page of the application, the error “Context Root Not Found” occurs in the browser.
How can the administrator resolve this error?

1. A. Restart the Liberty profile server.
2. B. Install the ServletApp.war file using the Integrated Solutions Console (ISC).
3. C. Place the ServletApp.war file in the directory named dropins under ${server.config.dir}.
4. D. Place the ServletApp.war file in the directory named applications under${server.config.dir}.

Correct Answer: D

A system administrator has created a Jython script called globalScript.py.
What should the administrator do to ensure globalScript.py is loaded when the wsadmin shell is used?

1. A. Compile globalScript.py to a Java class in the bin directory.
2. B. Invoke wsadmin with the argument –profileName globalScript.py.
3. C. Modify the configureCustomProperty script to import globalScript.py.
4. D. Set the script profiles in the wsadmin.properties file to load globalScript.py.

Correct Answer: D
wsadmin.properties has this entry com.ibm.ws.scripting.profiles where we can add the scripting files to be loaded.

A system administrator is required to monitor the application server logs for heap memory issues and determine if the heap memory usage is reaching close to 70% of the maximum heap. The application server is configured with an initial heap of 256 MB and a max heap of 1 GB.
How should the administrator determine if the application server is utilizing 70% of the max allocated heap memory?

1. A. Check the System logs for OutOfMemoryErrors.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.
2. B. Configure WebSphere Application Server to enable verbose garbage collection.Analyze the garbage collection cycles in the native logs.
3. C. Configure Initial heap to be equal to the max heap.Trigger a heap dump from theIntegrated Solutions Console (ISC).Analyze the heap dump.
4. D. Configure WebSphere Application Server to increase max heap.Trigger a heap dump from the Integrated Solutions Console (ISC).Analyze the heap dump.

Correct Answer: B
Enabling verboseGC (Garbage Collection) output is often required when diagnosing issues with WebSphere Application Server. Because verboseGC data is critical to troubleshooting memory and performance problems and the overhead is generally very low, you may want to consider proactively enabling it in your environment.

A system administrator discovers an issue that requires a change to a federated server. In this cell, WebSphere administrative security is enabled, but application security is not enabled.
How should the administrator make this change? The administrator should use:

1. A. a web browser to connect to the node agent https port.
2. B. a web browser to connect to the deployment manager admin_host port.
3. C. the job manager to submit a job to update the unmanaged server.
4. D. an ssh connection to the node and modify the client_types.xml file.

Correct Answer: B
The admin_host virtual host is used for access to the WebSphere administrative console. At installation time, the host is configured to match requests on the wc_adminhost and wc_adminhost_secure ports for the stand-alone server or deployment manager.
