While monitoring a cluster in the cell, the administrator notices that one server in the cluster periodically loses connections to the database. When this happens, requests to the server have a significantly decreased response time and various error conditions are listed in the log files for the server. Since the error codes are returned quickly, the server starts returning responses faster than the average service times for the application. Due to this, the weight for the server is increased and a large percentage of incoming requests are being routed to the erroneous server and the server is getting overloaded with requests.
How can the administrator detect these conditions in the future and take action to prevent this problem?

• A. Monitor the JVM heap usage to determine a new server weight.
• B. Enable the PMI Extended statistic set and use the Connection Pool summary report.
• C. Configure the on demand router (ODR) transport chain to tune inbound connections.
• D. Configure the storm drain health policy.

There are many applications deployed in a large WebSphere Application Server cluster. A system administrator is required to give Configurator role access to a developer for a single application deployed in that cluster.
How should the administrator meet this requirement and restrict Configurator role access for a single application?

• A. Create an administrative authorization group, scope it only for that application and create an Administrative user or group role to give Configurator access to the developer.
• B. Create a J2C authentication alias for that developer.
• C. Create an Administrative user role and provide Configurator access to the developer.
• D. Create an Administrative group role and provide Configurator access to the developer.

A system administrator ran the backupConfig command to backup the configuration using the -nostop option. The administrator changed the properties for the service integration environment by modifying the sib.properties file. During testing the administrator noticed
Service Integration Bus related errors and wanted to restore the service integration environment. The administrator used the restoreConfig command, but the tuning properties for the service integration environment were not restore.
How can the administrator prevent this issue?

• A. Use the manageprofiles command for both the backup and the restore.
• B. Use the restoreConfig command without -nostop for the restore.
• C. Use full repository checkpoint for both the backup and the restore.
• D. Use the restoreConfig command with -nostop for the restore.
• E. Use the backupConfig command without -nostop for the backup

Which one of the following options describes the runtime flow starting from the client browser in a clustered WebSphere Application Server Network Deployment topology?

• A. Application server -> node agent -> deployment manager -> load balancer
• B. Deployment manager -> node agent -> HTTP server plug-in -> HTTP server
• C. Load balancer -> HTTP server -> HTTP server plug-in -> application server
• D. HTTP server -> job manager -> admin agent -> HTTP server plug-in

In a test environment, a system administrator has configured an external HTTP server in the DMZ that is routing to a cluster of application servers.
The administrator wants to achieve higher performance when routing and prioritizing incoming requests to the back- end cluster.
How can the system administrator achieve this task?

• A. Set up a Caching Proxy server between the external web server and the application server.
• B. Place an On Demand Router (ODR) between the external web server and the application servers.
• C. Enable the prefer local option on the cluster members.
• D. Configure a cluster of external HTTP servers.
