Oracle WebLogic Server 12c: Advanced Administrator II Free Sample Questions

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?

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?

Case Study: FinCorp Global

FinCorp is migrating a legacy banking application to WebLogic 12c. The new architecture uses a Dynamic Cluster with 8 Managed Servers distributed across 4 machines. The requirement is to automate the installation of the domain on all 4 machines using a standard template.

You have created a domain template fincorp_domain.jar using the Template Builder on the first machine.

Which WLST command or utility should be used on the remaining three machines to create the domain configuration based on this template, and what is the primary consideration for the user_projects directory?

You are creating a custom Domain Template using the Domain Template Builder. You need to ensure that certain sensitive files (like custom keystores) in the source domain are included in the template, while temporary cache files are excluded.

Which configuration section of the Template Builder handles this requirement?

Which of the following statements accurately describes the difference between a Domain Template and an Extension Template in WebLogic Server 12c? (Select TWO)

You are configuring the Node Manager on a Linux host to manage three WebLogic domains. You want to ensure that if the physical server reboots, the Node Manager starts automatically, and subsequently restarts the Managed Servers that were running prior to the crash.

Which combination of actions achieves this?

True or False: When using the Java-based Node Manager, you must configure a separate Node Manager instance for every WebLogic domain on the same physical machine.

A Managed Server (MS1) is in the FAILED state. The Node Manager is configured to monitor this server.

What logic does the Node Manager follow to attempt a restart?

You need to update the MaxCapacity of a JDBC Data Source in a production environment without restarting the servers. You decide to use WLST.

Which WLST mode and command sequence is appropriate for this task?

Part 2: Automation

The operations team needs a WLST script to automate the creation of a new Managed Server and add it to the existing 'BankingCluster'. The script must handle the case where the server might already exist.

Below is a snippet of the script:

connect('weblogic', 'password', 't3://adminhost:7001')
edit()
startEdit()
cd('/')
if getMBean('Servers/NewServer') is None:
cmo.createServer('NewServer')
# MISSING CODE BLOCK
print 'Server created'
else:
print 'Server exists'
activate()

Which code block correctly assigns the new server to the cluster?

You are writing a WLST script to monitor the heap usage of a specific Managed Server. You are currently connected to the Administration Server.

Which MBean hierarchy must you navigate to access the runtime metrics of a Managed Server named 'MS1'?

In a WLST script, you need to encrypt a database password before setting it in a Data Source configuration.

Which command or method provides this functionality?

You want to record a WLST script based on your actions in the Administration Console to learn the correct MBean navigation and attribute names.

Where in the Administration Console do you enable this feature?

You are configuring Two-Way SSL (Client Certificate Authentication) for a WebLogic Server. You have imported the server's identity into the Identity Keystore.

What additional step is strictly required to allow the server to validate client certificates?

A WebLogic Server is behind a hardware load balancer (LBR). The LBR terminates SSL and forwards requests to WebLogic over HTTP. However, the application generates self-referential links using the 'http' protocol instead of 'https', causing browser warnings.

Which configuration setting on the WebLogic Server resolves this?

You have a domain with a Custom Identity Keystore and the Default Trust Keystore. You need to update the private key alias used by the server.

Which command line tool is used to manage the key-pair in the JKS file?

Part 3: Deployment

The development team has delivered a new version (v2) of the 'CoreBanking' application. The current version (v1) is running in production with active user sessions. You need to deploy v2 such that:

1. Existing users continue on v1 until their sessions expire.
2. New users are directed to v2.
3. You can rollback if v2 shows errors.

Which feature should you utilize?

You are planning a Zero Downtime Patching (ZDT) workflow for a WebLogic Server 12c domain containing a cluster of four Managed Servers. You intend to use the rolloutUpdate WLST command.

Which of the following prerequisites must be met before executing this command to ensure a successful rolling update without service interruption?
