NEW QUESTION 7
A system administrator completed a WebSphere Application Server installation by using the Installation Manager. During installation, all defaults were selected for the installation root directories and the shared resources directory. Over time, the administrator has updated the installation with various interim fixes and fix packs. The administrator notices that the shared resources directory is very large in size and grows larger each time the Installation Manager is run.
How can the administrator decrease the size and remove some of the content from the shared resources directory?

• A. Manually delete content from the directory.
• B. During an update, create a new shared resources directory.
• C. Clear the Delete Saved Files option for the Installation Manager.
• D. Set the preserveDownloadedArtifacts preference to false.

Answer: D

Explanation: Because product payloads are cached in this directory, space requirements can grow very large over the lifetime of the product, as service updates are applied. The WebSphere Application Server product image is large, so if this content is permitted to accumulate, then this directory will grow to be many gigabytes in size over the course of multiple fix pack applications. You should never manually delete the content in this folder. Instead, during any installation or maintenance operation, you can specify the following preference to remove some of the content in this folder:
–preferences com.ibm.cic.common.core.preferences.preserveDownloadedArtifacts=false

NEW QUESTION 8
A web application has a configured session timeout of eight hours and a default LTPA token timeout of two hours. After every two hours, the users have to log in again from their HTTP browser. The system administrator is required to make configuration changed so users only have to log in once, while keeping the above mentioned timeouts the same. The authentication mechanism available is Kerberos.
How should the administrator do this?

• A. Configure the SIP digest authentication.
• B. Configure the SPNEGO Web or SPNEGO TAI.
• C. Enable Session Management Security Integration.
• D. Ensure Web Inbound security attribute propagation is enabled.

Answer: B

Explanation: In WebSphere Application Server Version 6.1, a trust association interceptor (TAI) that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) to securely
negotiate and authenticate HTTP requests for secured resources was introduced. This function was deprecated In WebSphere Application Server 7.0. SPNEGO web authentication has taken its place to provide dynamic reload of the SPNEGO filters and to enable fallback to the application login method.

NEW QUESTION 9
A system administrator needs to view the list of certificates for unmanaged web server located on a remote system.
How should the administrator do this?

• A. View the plugin-cfg.xml
• B. Look at the SSL configuration in the httpd.conf
• C. Use iKeyman to view the keyring.
• D. Use the administrative console to check the content of the cell default keystore.

Answer: C

Explanation: You do not have a secure network connection until you have created a key for secure network communications and received a certificate from a certificate authority (CA) who is designated as a trusted CA on your server. Use IKEYMAN to create the key database file, public-private key pair, and certificate request. After you receive the CA-signed certificate, use IKEYMAN to receive the certificate into the key database where you created the original certificate request.

NEW QUESTION 11
A system administrator was asked by the development team to inform them of any warning message which contains a string “Connection” on a WebSphere Application Server with High Performance Extensible Logging (HPEL) enabled.

• A. Configure log detail levels to include filter on “Connection” string.
• B. Use the Log Viewer in the administrative console with filter on “Connection” string.
• C. Use the logviewer.sh or logviewer.bat command with appropriate options.
• D. Use the Log Viewer in the administrative console with filter on “Connection” string and enable the “Refresh automatically” feature.

Answer: C

Explanation: The High Performance Extensible Logging (HPEL) facility writes to the log and trace repositories in a binary format. You can view, query and filter the repository using the LogViewer command.
logviewer.sh -monitor -includeLoggers Connection
-monitor [integer]Specifies that you want the logViewer to continuously monitor the repository and output new log record entries as they are created. You can provide an optional integer argument after this parameter to specify how often you want the LogViewer tool to query the repository for new records. By default the logViewer queries the repository for new records every 5 seconds. When used with other filtering options, only those new records that match the filter criteria are displayed.

NEW QUESTION 12
A system administrator has configured a cluster containing 40 servers. The cluster members all belong to one core group. While examining the log files, the administrator notices that the core group coordinator is consuming abnormally high amounts of memory and CPU resources.
How can the system administrator reduce the memory and CPU resource usage of the core group coordinator?

• A. Configure a core group bridge.
• B. Configure a second active coordinator.
• C. Decrease the memory on the machine.
• D. Move the coordinator to another machine.

Answer: B

Explanation: Remember that coordinator election occurs whenever the view changes. Electing a new coordinator uses a lot of resources because this process causes increased network traffic and CPU consumption. Specifying a preferred coordinator server, whenever practical, helps eliminate the need to make frequent coordinator changes.
