About the Oracle WebLogic Server 12c: Administration I Exam

WebLogic administration involves understanding how domain configuration is managed and how managed servers support deployed applications. Practice topics include identifying the Administration Server’s role, configuring data sources and their JNDI names for application access, and distinguishing network channels used for traffic handling, including secure listening. Cluster-wide JNDI supports resource and application lookup across cluster members, while work managers help allocate server resources to work. Operational decisions also include setting JVM heap boundaries and avoiding inconsistent configuration edits when making changes outside the Administration Console. Deployment-state checks help administrators verify whether an application is available without inspecting its source code. These concepts connect configuration choices to application connectivity, traffic routing, resource use, and routine troubleshooting in a WebLogic Server environment.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

In a WebLogic Server cluster, what is the role of a cluster-wide JNDI tree?

  1. AIt provides a shared naming view for resources and objects across cluster members
  2. BIt synchronizes operating-system user accounts across hosts
  3. CIt stores replicated application source code
  4. DIt replaces each server's local configuration file
Show answerCorrect answer: A

Cluster members can expose and access clustered naming information through a cluster-wide JNDI tree, allowing clients and applications to locate resources across the cluster.

Question 2

An administrator needs to create a JDBC connection pool for applications in a domain. Which resource should be configured?

  1. AA JDBC data source
  2. BA JMS connection factory
  3. CA virtual host
  4. DA server log filter
Show answerCorrect answer: A

A JDBC data source provides applications with database connectivity and manages a pool of database connections. Its configuration includes database connection properties and targets.

Question 3

Which statement describes the role of a WebLogic Server network channel?

  1. AIt defines a logical communication path with settings such as protocol, address, and port
  2. BIt specifies which database tables an application may access
  3. CIt records the sequence of edits made in the Administration Console
  4. DIt determines the JVM garbage-collection algorithm for a server
Show answerCorrect answer: A

A network channel represents a configured communication path for server traffic. Its settings can include the protocol, listen address, port, and related connection properties.

Question 4

In a WebLogic Server domain, what is the primary role of the Administration Server?

  1. AIt hosts all application traffic for every managed server by default
  2. BIt provides a central point for configuring and monitoring the domain
  3. CIt automatically replicates every application database
  4. DIt replaces the Node Manager on each machine
Show answerCorrect answer: B

The Administration Server hosts the domain’s central administration tools and configuration service. Managed Servers can host application workloads independently.

Question 5

What does a WebLogic Server work manager primarily help administrators control?

  1. AHow application work is prioritized and scheduled for execution
  2. BHow domain configuration files are encrypted
  3. CHow server listen ports are assigned automatically
  4. DHow application archives are compressed during deployment
Show answerCorrect answer: A

Work managers provide policy-based control over the scheduling and allocation of threads for application work, helping manage execution priorities and constraints.

Question 6

What is the primary function of a WebLogic Server data source's JNDI name?

  1. AIt identifies the server's network interface
  2. BIt gives applications a lookup name for obtaining the data source
  3. CIt specifies the database's transaction log location
  4. DIt selects which JVM will host the data source
Show answerCorrect answer: B

Applications commonly look up a data source by its JNDI name through a naming context, then use the returned resource to obtain connections.

Question 7

A server is configured with a minimum and maximum heap size for its JVM. What is the main operational reason to set the minimum and maximum heap sizes to the same value in some deployments?

  1. ATo reduce heap resizing during operation and provide a predictable heap allocation
  2. BTo enable application staging automatically
  3. CTo make the server join a cluster without a restart
  4. DTo encrypt the domain configuration file
Show answerCorrect answer: A

Setting equal initial and maximum heap sizes can avoid JVM heap expansion and provide more predictable memory allocation behavior, though the appropriate values depend on workload and JVM guidance. Heap settings do not control staging, cluster membership, or configuration-file encryption.

How to use this practice test

Access is free. A session presents up to 20 random questions from the 50-question bank, covering WebLogic administration vocabulary and scenarios. Results appear after the session, so use them to identify concepts to revisit, such as JNDI lookup, data source configuration, channels, or deployment-state checks.

Preparation tips

  • Map the relationship among a WebLogic domain, its Administration Server, managed servers, and cluster members; note which server role handles domain configuration.
  • Practice tracing an application’s database access from a JDBC data source through its JNDI name, and distinguish that lookup from cluster-wide JNDI behavior.
  • Compare network-channel settings for traffic handling with the configuration needed for an HTTPS listening channel.
  • Review how work managers control work allocation and how JVM minimum and maximum heap settings affect server operations.
  • For troubleshooting scenarios, connect deployment-state reporting and disciplined offline configuration edits to safe verification and change management.
