When installing applications to IBM WebSphere Application Server, what is one important
difference between RAR files and SAR, WAR, EAR, and JAR files?
A.
They contain no Java code.
B.
They are deployed to the web server.
C.
They can be installed at different scopes.
D.
They use a different compression protocol
They are deployed to the web server.
What is the default location for heap dumps?
A.
/logs
B.
/profiles/logs
C.
/logs/server1
D.
<profile_root>/<profile>
<profile_root>/<profile>
How can an administrator deploy or update an EAR, JAR, WAR, or SAR file to an application server or cluster in a development environment?
A.
Place the file in the monitored directory.
B.
Place the file in the operating system defined temporary directory.
C.
Place the file in the operating system defined user home directory for the user that owns
the Java process.
D.
Email the file to wasadmin@hostname.com, where hotname.com is the host of the IBM WebSphere Application Server.
Place the file in the monitored directory.
Explanation:
You can install an enterprise application file on an application server or cluster by dragging
or copying an enterprise archive (EAR), web application archive (WAR), Java archive
(JAR), or Session Initiation Protocol (SIP) archive (SAR) to a monitored directory.

How can an administrator reduce overhead when utilizing monitored directories?
A.
Increase the polling interval so that the process runs less often.
B.
Decrease the amount of time that the monitored directory is accessible by users.
C.
Decrease the size of the monitored directory so that larger files will not be able to be stored in it.
D.
Configure the monitored directory settings to not automatically synchronize the
application once it is installed.

What can an administrator use to remotely manage multiple stand-alone (unfederated) application servers?
A.
Job Manager
B.
Administrative agent
C.
Deployment manager
D.
remoteServer.jacl script
Job Manager
Explanation:
Administering nodes remotely using the job manager
In a flexible management environment, you can asynchronously submit and administer jobs
for large numbers of stand-alone application servers, deployment managers, and host
computers over a geographically dispersed area. At the remote machines, you can use
jobs to manage applications, modify the product configuration, or do general purpose tasks
such as run a script.

In addition to logging changes, what can Cross Component Trace capture?
A.
The user agent of the browser that has initiated the request.
B.
The last time that the component was updated by a code deploy.
C.
The time that the component was started in the application server.
D.
Data snapshots that store entire request and response bodies on the file system.
The time that the component was started in the application server.
Explanation:
Cross Component Trace (XCT) annotates the logs so that log entries that are related to a
request that is serviced by more than one thread, process, or even server are identified as
belonging to the same unit of work.
XCT log records are typically added to the logs to:

An administrator notices a sudden increase in the user load that causes resource
contention on the database server.
What preventive measure can the administrator take to avoid database outage?
A.
Enable surge protection.
B.
Configure Stuck connection.
C.
Reduce connection pool size.
D.
Reduce WebContainer Thread pool size
Reduce connection pool size.
Explanation:
Maximum Connection Pool Size
When determining the maximum size of the database connection pool, consider the
following issues:
The total number of connections that the WebSphere Commerce cluster can open to the
database should not overwhelm your database.

When updating an application, what is important to keep in mind?
A.
The application is only updated during the next server restart.
B.
The application is automatically stopped, updated, and restarted.
C.
The application is only updated during the next restart of the application.
D.
The application is stopped, updated, and restarted at the scheduled time.
The application is automatically stopped, updated, and restarted.
Explanation:

automatically stops the application, updates the application logic and restarts the
application.
