Create and manage WebLogic domains · Perform a "rolling upgrade" and differentiate it from other upgrade methods
A middleware engineering team is planning to apply a Critical Patch Update (CPU) to a highly available WebLogic 14c cluster without incurring application downtime. They intend to use the zero-downtime (ZDT) rolling upgrade feature. Which of the following accurately describes a requirement for executing a rolling patch upgrade?
Show answer & explanation
Correct answer: B
During a rolling upgrade, the Oracle best practice and requirement is to always upgrade/patch the Administration Server first. Once the Admin Server is running on the new patch level, the Managed Servers are patched and restarted sequentially (or in batches) to ensure zero downtime.

Create and manage WebLogic domains · Define the purpose and functionality of Managed Server Independence Mode
Company XYZ has a WebLogic 14c domain consisting of an Administration Server on Machine A and a Managed Server (Server_1) on Machine B.
Due to a network outage, Machine B loses connectivity to Machine A. The Administration Server crashes shortly after. While the network is still down, the OS on Machine B is rebooted. Node Manager attempts to start Server_1 automatically.
Under what condition will Server_1 successfully start despite the Administration Server being unavailable?

Correct answer: B
Managed Server Independence (MSI) allows a Managed Server to start without connecting to the Admin Server. It requires a cached copy of the domain's config.xml and a valid boot.properties (or serialized system.ini/Security credentials) to bypass the need to fetch configuration and authenticate against the Admin Server at startup.

Create and manage WebLogic domains · Use Pack and Unpack utilities to migrate a WebLogic domain to another system
You are tasked with expanding an existing WebLogic 14c domain to a new remote physical server. You decide to use the Pack and Unpack utilities. Which TWO of the following statements are correct regarding the use of these utilities for this purpose? (Select TWO)
Show answer & explanation
Correct answers: A, C
To create a template for a remote Managed Server, you must use
-managed=truewith the pack command so that it only includes the necessary files for a Managed Server, omitting Admin Server specific configurations.The unpack utility takes the JAR template created by the pack utility and extracts it on the target machine, creating the necessary domain directory structure required to start the Managed Server.
- Question 4Beginner
Create and manage WebLogic domains · Execute silent installation of WebLogic Server
When performing a silent installation of WebLogic Server 14c on a Linux environment, you must provide a pointer to the central inventory location. The file that defines this inventory pointer is typically named: _________
Show answer & explanation
Correct answer: B
The 'oraInst.loc' file contains the location of the Oracle Inventory directory and the OS group name that has write permissions to that directory. It is required during a silent installation on UNIX/Linux systems using the -invPtrLoc flag.
- Question 5Intermediate
Create and manage WebLogic domains · Differentiate between configured and dynamic clusters in WebLogic Server
A cloud architect is redesigning a legacy WebLogic application to support automatic elasticity based on traffic load. They are migrating from a traditional Configured Cluster to a Dynamic Cluster in WebLogic 14c. What is the fundamental mechanism that allows a Dynamic Cluster to easily scale out compared to a Configured Cluster?
Show answer & explanation
Correct answer: B
Dynamic clusters use a Server Template that contains common settings. WebLogic calculates the server configurations dynamically based on the template and the maximum number of servers specified, eliminating the need to manually configure each server instance.
- Question 6Advanced
Create and manage WebLogic domains · Configure and manage Coherence servers, ensuring high availability and scalability in a WebLogic environment
You are integrating Oracle Coherence with a WebLogic 14c domain to provide a highly available, distributed caching tier. To achieve this, you need to configure Managed Coherence Servers. Which operational step is required to properly associate the Coherence cluster with the WebLogic environment?
Show answer & explanation
Correct answer: A
To manage Coherence within WebLogic, you define a Coherence Cluster System Resource (which encapsulates the Coherence configuration) and target it to a WebLogic cluster or individual Managed Servers. These targeted servers then become Managed Coherence Servers.
