Your domain consists of 30 servers. You are using the Administration Console. Which is the quickest way to identify the servers that are in a Failed health state?

The WebLogic Server Administration Console provides a centralized view for monitoring the entire domain. The most efficient method to identify servers in a specific health state, such as "Failed," is to navigate to the domain's main monitoring page. The Domain > Monitoring > Health tab displays a summary table of the health states for all servers. This page includes a "Filter" or "Customize this table" feature, allowing an administrator to quickly display only the servers that match a specific criterion, such as "Health State is Failed." This approach is significantly faster than checking each of the 30 servers individually.

B. Use the Monitoring >Health tab for each server in the domain. This is incorrect because it requires manually navigating to each of the 30 servers' individual monitoring pages, which is highly inefficient and time-consuming.
C. Write a custom WLST script to print out failed server. While possible, writing and running a WLST script is not the "quickest" way compared to using the built-in, real-time GUI feature, especially when already using the Administration Console.
D. Capture a diagnostic snapshot. This is incorrect as a diagnostic snapshot is a heavyweight tool for deep, offline troubleshooting and post-failure analysis, not for a quick, real-time status check of server health. ---

Chapter 6: Monitoring a WebLogic Server Domain.

Section: Monitor server health: This section details the process of using the Administration Console to view server health. It states

"The Server Health page displays monitoring information for each server in the domain... You can see the server's current health state..." The page also describes the "Customize this table" link

which allows for filtering the results shown. This directly supports option A as the quickest method.

Chapter 2: Understanding the WebLogic Diagnostic Framework.

Section: Diagnostic Image Capture: This document describes a diagnostic image as a capture of server state primarily used for "post-failure analysis." This confirms that generating a diagnostic image is not a quick method for real-time health monitoring

making option D incorrect.

state command.

The documentation for the state command shows it can be used to retrieve the current state of a server. While this confirms the technical feasibility of option C

it is a command-line approach that requires scripting

which is generally not faster for a simple visual check than using the dedicated monitoring UI in the console.
