Correct Answer: D

Servicing only administrative requests: Specifies that WebLogic Server make the application available in Administration Mode only. While in Administration mode, the application can be accessed only by internal clients through a configured Administration port.

Correct Answer: BC

The pool size has decreased from a maximum 20 to 10.

The workload has been 20. Now it is 10. The workload was higher.

Note: Current Capacity: The current count of JDBC connections in the connection pool in the data source.

Current Capacity High Count: Highest number of database connections available or in use (current capacity) in this instance of the data source since the data

source was deployed.

Note:

Incorrect answers:

E, F: The statement cache deals with statements. Current capacity and Current Capacity High Count deals with connections.

Statement Cache Size shows the total number of statements to cache for each connection in each instance of the data source. WebLogic Server can reuse

statements in the cache without reloading the statements, which can increase server performance. Each connection in the connection pool has its own cache of

statements.

Correct Answer: C

A managed server (not a CMO, not an administration server) is created.

Port is 8008.

Note: Listing: Creating a Managed Server

connect("username","password")

edit()

startEdit()

svr = cmo.createServer("managedServer")

svr.setListenPort(8001)

svr.setListenAddress("my-address")

save()

Correct Answer: C

File persistence use less memory than in-memory replication, and does not need access rights to the company's database.

Note:

You use session persistence to permanently store data from an HTTP session object to enable failover and load balancing across a cluster of WebLogic Servers.

When your applications stores data in an HTTP session object, the data must be serializable. There are five different implementations of session persistence:

*

Memory (single-server, non-replicated)

*

File system persistence

*

JDBC persistence

*

Cookie-based session persistence

*

In-memory replication (across a cluster)

Incorrect answers:

A: Using in-memory replication, WebLogic Server copies a session state from one server instance to another. The primary server creates a primary session state on the server to which the client first connects, and a secondary replica on another WebLogic Server instance in the cluster. The replica is kept up-to-date so that it may be used if the server that hosts the servlet fails.

D: JDBC persistence stores session data in a database table using a schema provided for this purpose. You can use any database for which you have a JDBC driver. You configure database access by using connection pools.

Note: When you use memory-based storage, all session information is stored in memory and is lost when you stop and restart WebLogic Server.

Correct Answer: B

A WebLogic domain can be composed of a number of WebLogic instances, and several of these servers may be grouped into clusters. For instance, you could set up a cluster of WebLogic servers, all of which host your web application and related resources. This cluster of servers could be fronted by a load balancer that distributes requests evenly across all the members of the cluster. The load balancer could itself be another WebLogic instance. All server instances must belong to the same WebLogic domain. Thus, a WebLogic cluster is a group of servers working together with services, such as clustered JNDI, to provide support for failover and load balancing. A domain may in turn have a number of WebLogic instances, several groups of which can be placed into different clusters.
