A. Starts a Managed server

B. Starts a machine

C. Calls the startManagedWebLogic.sh script in the domains bin directory

Question 2

Which two statements are true about WebLogic data sources? (Choose two.)

A. Data sources are bound in the JNDI tree of a server.

B. Data sources are based on the JMS specification.

C. Data sources are targeted to a domain.

D. A domain requires at least one data source.

Question 3

You set up two network channels for server-to-server communication. You want channel X to be used more than channel Y, so you give channel X a higher Channel Weight. You want to see if indeed channel X is used more.
You use the administration console and look at both channels under each one's Monitoring tab. What scenario would best assure you that channel X has an overall higher connection rate?

A. Channel X Connections is higher.

B. Channel X Bytes Received is higher.

C. Channel X Accept Count is higher.

D. Channel X Bytes Sent is higher.

Correct Answer: A

Question 4

You are using the Configuration Wizard to create a new domain that will host an EJB application without a cluster. Remote EJB clients can therefore take advantage of WebLogic Server's load balancing and failover capabilities.
However, a proxy server exists between the EJB clients and this new cluster.
Which cluster attribute should you modify in the Configuration Wizard to ensure that external EJB clients are routed correctly through the proxy?

A. Cluster Type

B. Broadcast Channel

C. Messaging Mode

D. Replication Channel

E. Cluster Address

Correct Answer: E

Question 5

A domain defines four machines: host01, host02, host11, and host12. It also defines a dynamic cluster whose Machine Name Match Expression is set to the value "host1*".
Which of the machines will be used to host servers in this dynamic cluster?

A. host01 only

B. host11 and host12 only

C. all machines

D. host01 and host11 only

E. host11 only

F. the default machine of the domain

Correct Answer: B

Question 6

Consider an application that comprises both web and EJB components.
What are two benefits of implementing a multitier cluster architecture over a single-tier(basic) cluster architecture? (Chose two.)

A. All servers can be managed (started/stopped) together

B. Each cluster can be scaled independently

C. Dynamic clusters are only supported for the multitier architecture

D. Remote EJB access is blocked

E. Future web clusters can share the same EJB tier

Correct Answer: A,E

Question 7

One of your applications sends SQL requests to a back-end database. Today some of these requests are very slow to complete and users are waiting an unusually long time before getting the information back. You decided to take a look at a thread dump and found several threads with a stack similar to:

What should be your initial assumption and first action?

A. The response data provided by the database SQL is larger than the receive socket buffer, so you just need to increase the buffer

B. The Oracle JDBC driver got corrupted and needs to be reinstalled or replaces with a different driver

C. The activity on the database side needs to be checked with your DBA to verify if the connection request was received and how it's been handled by the database

D. The datasource connection was leaked and needs to be reset

E. A firewall is blocking the connection between WebLogic Server and the back-end database. This needs to be immediately addressed with your network administrator

F. The maximum capacity of the connection pool was reached due to higher load than usual and you just need to wait until new connections get released or increase the capacity of the pool. This can be done in the Admin Console.
