You decide to use the 'Record' feature in the WebLogic Administration Console to generate a WLST script based on your configuration actions.
Which of the following is a limitation of this recording feature?
Show answer details
Correct answer: A
The Script Recording feature in the WebLogic Console captures changes made to the configuration MBeans (config.xml). Operations involving the Security Realm (users, groups, roles) interact with the LDAP server or security providers directly and are NOT recorded by the configuration recorder.
- 2
You are configuring Two-Way SSL for a WebLogic Server. The server needs to map the client certificate presented by the browser to a specific WebLogic user based on the Common Name (CN) field.
Which WebLogic security provider component must be configured to achieve this?
Show answer details
Correct answer: A
The Identity Asserter is responsible for validating tokens (like X.509 certificates) and mapping them to a WebLogic user. Specifically, you configure the Default Identity Asserter to support the 'X.509' token type and define 'User Name Mapper' logic (or use the default logic) to extract the user from the certificate Subject.
- 3
Your security team requires that all WebLogic Servers enforce TLS 1.2 as the minimum protocol version for SSL connections. You are using the JSSE provider.
Which Java system property should be added to the server startup arguments?
Show answer details
Correct answer: A
This system property explicitly instructs the WebLogic JSSE provider to use TLS 1.2. While there are other properties for older SSL implementations, this is the standard for enforcing protocol versions in modern WebLogic JSSE configurations.
- 4
You are creating a Deployment Plan (
plan.xml) for a web application. You need to override thecontext-rootdefined in theweblogic.xmldescriptor for the production environment.Which element in the deployment plan is used to define the new value?
Show answer details
Correct answer: B
In a WebLogic deployment plan,
- 5
You are performing Production Redeployment of an application. The 'Retirement Policy' is set to 'Graceful'.
What happens to the existing active sessions on the old version (Version A) when the new version (Version B) is started?
Show answer details
Correct answer: A
This is the core behavior of Production Redeployment. Existing sessions remain 'pinned' to the old version to ensure continuity. New sessions are routed to the new version. The old version is only retired once all sessions end or the timeout occurs.
- 6
You are deploying a shared Java EE library named
CommonUtils. TheMANIFEST.MFof the library JAR contains:Extension-Name: CommonUtilsSpecification-Version: 2.0Implementation-Version: 2.0.1An application referencing this library requests
Specification-Version: 2.0.Later, you deploy a new version of the library with
Implementation-Version: 2.0.2(same Specification Version).Which library version will the application use upon restart?
Show answer details
Correct answer: A
When an application requests a library by Specification Version (and does not specify an exact Implementation Version), WebLogic Server will automatically select the deployed library with the highest Implementation Version that matches the requested Specification Version.
- 7
You want to configure a Work Manager to prioritize requests from users belonging to the 'GoldMember' group over standard users. Which type of Request Class should you configure?
Show answer details
Correct answer: C
A Context Request Class allows you to define request priority based on context information, such as the current user's group or Principal. This is specifically designed for 'Gold/Silver/Bronze' user segmentation scenarios.
- 8
You have a Work Manager configured with a
Capacity Constraintof 50. What happens when the 51st concurrent request arrives for that Work Manager?Show answer details
Correct answer: A
A Capacity Constraint limits the total number of requests that can be queued or executing. Once this limit is reached, WebLogic Server rejects subsequent requests immediately to prevent server overload.
- 9
You are configuring an Active GridLink Data Source to connect to an Oracle RAC database. You need to ensure the WebLogic Server receives Fast Application Notification (FAN) events from the database.
What specific component within the GridLink configuration must be properly configured to enable this?
Show answer details
Correct answer: D
GridLink Data Sources rely on the Oracle Notification Service (ONS) to receive asynchronous FAN events (like 'Service Down' or 'Load Balancing Advisory') from the RAC cluster. You must configure the ONS node list and potentially the ONS wallet.
- 10
You have a Multi Data Source configured with the Failover algorithm containing
DS1(primary) andDS2(secondary).DS1fails, and WebLogic switches toDS2.When
DS1becomes available again, what determines if and when WebLogic switches back toDS1?Show answer details
Correct answer: A
By default in the Failover algorithm, WebLogic does not automatically 'fail back' to the primary just because it recovers. It stays on the secondary until the secondary fails (or the server is restarted/reset). This prevents 'flapping' between data sources.
- 11
A financial institution is performing a rolling upgrade of a WebLogic Server 12c cluster hosting a critical payment processing application. The cluster spans four Managed Servers across two physical machines (Machine A and Machine B). The administrator has already upgraded the Oracle Home on Machine A.
Which sequence of steps ensures the application remains available to clients throughout the process while upgrading Machine A's servers?
Show answer details
Correct answer: D
In a rolling upgrade, you upgrade a subset of the cluster (Machine A) while the others (Machine B) continue to service requests. After patching/upgrading the Oracle Home for Machine A, you restart those servers pointing to the new binaries. Once they are running and verified, you proceed to Machine B. This maintains availability.
- 12
You are designing a Zero Downtime Patching strategy for a WebLogic domain. The domain currently shares a single Middleware Home on a shared NAS storage device mounted by all UNIX hosts.
Why is this architecture unsuitable for a rolling patch upgrade, and what is the required architectural change?
Show answer details
Correct answer: D
If all servers share a single Middleware Home directory, you cannot patch it without shutting down all servers effectively (or risking corruption/locks). For a rolling upgrade, you need at least two installation directories (or redundant homes) so one can be patched while the other runs the active servers.
