Oracle 1Z0-133 Sample Questions:

01. In-memory HTTP session replication in a production WebLogic Server 12c cluster has become slow. You find that replication traffic is competing with heavy application request traffic on the members' default network channel and single network interface. You decide to define a dedicated replication channel so that replication traffic uses a separate network interface.
Which statement correctly describes what is required for this to work?
a) The replication channel is configured just once on the Administration Server, which then relays all of the cluster's replication traffic between the managed servers on their behalf.
b) Defining the replication channel only on the cluster's primary server is sufficient, because at runtime that server automatically pushes the channel definition out to each of the secondary members that store session copies.
c) A network channel reserved for replication must be defined with the same channel name on every member of the cluster, and the cluster must be configured to use that channel for replication.
d) You must first switch the cluster from in-memory replication to JDBC session persistence before a dedicated replication network channel can take effect at all.
 
02. Two administrators, working in separate Administration Console sessions in a production-mode domain, are troubleshooting a configuration problem. The first administrator clicks Lock & Edit and begins changing several attributes. Shortly after, the second administrator tries to click Lock & Edit to make his own edits.
Which two statements correctly describe this situation and how to resolve it?
(Choose two.)
a) Production mode allows editing without any lock, so this contention cannot occur
b) The two sets of pending changes are merged automatically when the second administrator saves
c) The second administrator's Lock & Edit silently seizes and keeps the first administrator's pending changes
d) Both administrators can hold the edit lock at the same time as long as they edit different resources
e) The second administrator cannot acquire the edit lock, because only one edit session can hold it at a time
f) Once the first administrator activates or undoes the pending changes and releases the lock, the second administrator can then edit
 
03. After a production redeployment you need to confirm that the new version is actually processing traffic, by watching per-application runtime measurements such as request throughput and response time over the next several minutes.
Which facility is designed to chart these live application metrics?
a) The domain's config.xml file opened and read directly on disk in a plain text editor.
b) The Monitoring Dashboard, which can graph runtime metrics for the deployed application as time-series charts.
c) The Change Center, by repeatedly locking, editing, and then activating the pending domain configuration changes.
d) The Configuration Wizard's final summary screen that is shown right after a domain is created or extended.
 
04. Your team applies periodic domain updates and reconfigurations. You must add several entries to the server CLASSPATH and set a couple of environment variables, and you want these customizations applied automatically at every server start and preserved across future domain updates rather than overwritten.
Which approach should you use?
a) Edit the domain's startWebLogic.sh script directly and append your extra CLASSPATH entries and environment variables to it so they load at each start.
b) Edit commEnv.sh under the WebLogic product home so the CLASSPATH and variable changes apply to every domain on the machine.
c) Create a setUserOverrides.sh script in the domain's bin directory, which the generated domain environment scripts source automatically at startup.
d) Edit the domain's setDomainEnv.sh script directly and add your extra CLASSPATH entries and environment variables to its existing settings.
 
05. While editing configuration in the Administration Console, an administrator has made several changes during the current edit session but has not yet activated them. He decides the edits are wrong and wants to abandon all of them at once, leaving the running configuration untouched.
Which Change Center action accomplishes this?
a) Undo All Changes
b) Release Configuration
c) Activate Changes
d) Lock & Edit
 
06. A developer's web application borrows connections from a WebLogic data source during each request. Under sustained load the application begins throwing errors that the pool has reached its maximum capacity, even though the database itself is healthy and responsive.
Which two statements describe correct use of a WebLogic data source that avoids this problem?
(Choose two.)
a) The data source should be obtained through a JNDI lookup of its configured JNDI name, then getConnection() called to borrow a pooled connection.
b) The connection should be released in a finally block; calling close() returns it to the pool rather than physically closing the database connection.
c) Each request should load the JDBC driver class and open its own connection directly to guarantee isolation from other requests.
d) Calling close() should be avoided because it destroys the physical database connection and forces the pool to grow again.
e) Keeping a connection open across successive requests improves performance by avoiding repeated pool lookups.
 
07. Examine the following server log entry:
####<Jun 3, 2013 2:14:07 AM UTC> <Critical> <WebLogicServer> <host07> <managed3> ... <The server health has changed to FAILED.>
Which statement is the correct interpretation of this entry?
a) The message was logged at Critical severity by the WebLogicServer subsystem, reporting that the server's health state changed to FAILED
b) It is a routine Informational-severity notice emitted by the JDBC subsystem reporting that a connection pool has reached its maximum capacity
c) The token Critical identifies the log rotation policy that archived and reset the log file
d) The token WebLogicServer names the physical machine or host that produced and emitted the message
 
08. Rather than introduce a separate web server, your team wants to use a dedicated WebLogic Server instance as the HTTP proxy that load-balances and fails over client requests across the cluster's managed servers.
Which approach implements this?
a) Enable the mod_wl_ohs plug-in module on the proxy WebLogic Server instance so that it front-ends the cluster
b) Configure a dedicated network channel on each managed server in the cluster that forwards incoming client traffic to the proxy instance
c) Add the proxy instance as a member of the cluster itself so that it multicasts each incoming client request out to the other managed-server members for handling
d) Deploy a web application that maps HttpClusterServlet on the proxy WebLogic Server instance, configured with the cluster's managed-server addresses
 
09. An organization publishes several web applications from one WebLogic Server instance and wants incoming requests directed to the correct application based on the DNS host name used to reach the server.
Which WebLogic Server feature routes requests to targeted web applications according to the requested host name?
a) Virtual host
b) Replication channel
c) Administration port
d) Network channel
 
10. You must install WebLogic Server on a host that has no graphical display, and you want the installation to complete without prompting the user for any input.
Which mode of the generic JAR installer meets this requirement?
a) Graphical mode, run through the windowed installer
b) Silent mode, driven by a response file
c) Reconfiguration mode, used to upgrade an existing domain
d) Configuration Wizard mode, used after the product is installed
