Question 1

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

Accepted Answer

An Extension Template is used to add applications, services, or resources to an existing domain.

Accepted Answer

A Domain Template defines the full infrastructure of a domain, including the Administration Server.

Answer

Extension Templates always overwrite the Administration Server configuration.

Answer

An Extension Template can be used to create a new domain from scratch.

Answer

A Domain Template cannot contain JDBC resources.

Question 2

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?

Accepted Answer

Set `CrashRecoveryEnabled=true` in `nodemanager.properties` and add the `startNodeManager.sh` script to the OS initialization system (e.g., systemd or init.d).

Answer

Set `AutoRestart=true` in `config.xml` for each server and run `installNodeManagerService.sh`.

Answer

Configure the `PostBindUID` and `PostBindGID` in `nodemanager.properties`.

Answer

Use the WLST command `nmEnroll` with the `autoStart` flag set to true.

Question 3

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.

Accepted Answer

False

Answer

True

Question 4

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?

Accepted Answer

It attempts to restart the server up to a configured `RestartMax` number of times within a `RestartInterval`. If it fails more than this limit, the state is left as FAILED.

Answer

It immediately kills the Java process and restarts it indefinitely.

Answer

It waits for an Administrator to issue a `nmStart` command via WLST.

Answer

It migrates the server to another machine immediately.

Question 5

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?

Accepted Answer

Online Mode: `connect`, `edit`, `startEdit`, `cd` to the JDBCSystemResource, `cmo.setMaxCapacity`, `save`, `activate`.

Answer

Offline Mode: `readDomain`, `cd`, `set`, `updateDomain`, `closeDomain`.

Answer

Offline Mode: `readTemplate`, `create`, `writeDomain`.

Answer

Online Mode: `connect`, `config`, `cd` to JDBC, `set`, `save`.

Question 6

Case Study: FinCorp Global

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:

```python
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?

Accepted Answer

cd('/Servers/NewServer')
cmo.setCluster(getMBean('/Clusters/BankingCluster'))

Answer

cd('/Servers/NewServer')
set('Cluster', 'BankingCluster')

Answer

assign('Server', 'NewServer', 'Cluster', 'BankingCluster')

Answer

cd('/Clusters/BankingCluster')
cmo.addServer('NewServer')

Question 7

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'?

Accepted Answer

`domainRuntime()` -> `ServerRuntimes` -> `MS1` -> `JVMRuntime`

Answer

`config()` -> `Servers` -> `MS1`

Answer

`edit()` -> `Servers` -> `MS1`

Answer

`serverRuntime()` -> `JVMRuntime`

Question 8

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?

Accepted Answer

encrypt()

Answer

loadProperties()

Answer

weblogic.Admin

Answer

storeUserConfig()

Question 9

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?

Accepted Answer

Click the 'Record' button in the toolbar of the console header.

Answer

User Preferences -> General -> Record Script

Answer

It is not possible in the Console; you must use the `record()` command in WLST.

Answer

Domain Structure -> Configuration -> Scripting

Question 10

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?

Accepted Answer

Set the 'Client Certs Requested and Enforced' attribute and populate the Trust Keystore with the CA certificates that signed the client certificates.

Answer

Configure a WebLogic Proxy Plug-in to terminate SSL.

Answer

Enable 'Hostname Verification' on the server.

Answer

Import the client's private key into the server's Identity Keystore.

Question 11

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?

Accepted Answer

Enable 'WebLogic Plugin Enabled' on the Server or Cluster configuration.

Answer

Enable JSSE SSL implementation.

Answer

Configure the Frontend HTTP Port to 443.

Answer

Import the LBR certificate into the WebLogic Identity Keystore.

Question 12

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?

Accepted Answer

keytool

Answer

wlconfig

Answer

CertGen

Answer

openssl
