問題 #98
Which two tasks are performed by the Routing Engine in a Junos device? (Choose two.)
答案：A,D
解題說明：
The Routing Engine (RE) functions as the centralized processor and administrative core of any Junos OS-based platform. Its primary responsibility involves the execution and maintenance of the control plane, which includes running all active routing protocols such as OSPF, BGP, and IS- IS. Through these protocols, the RE exchanges topology information with neighboring routers, builds the Routing Information Base (RIB), and calculates the optimal paths for traffic. Once these paths are determined, the RE distributes the resulting Forwarding Information Base (FIB) to the Packet Forwarding Engine (PFE) for hardware-level execution.
In addition to its protocol duties, the Routing Engine manages the device configuration and the overall system environment. This includes providing the user interface (CLI or J-Web), managing the candidate and active configuration databases, and handling the commit process. While the PFE is specifically designed to forward transit traffic and evaluate that traffic against firewall filters at line rate, the RE focuses on the higher-level logic and management tasks. This architectural separation ensures that management functions--such as a complex configuration commit or a protocol re-convergence event--do not degrade the performance of the data plane, allowing the device to continue forwarding user traffic without interruption.
問題 #99
Which command would you use to gracefully power off a Junos device?
答案：B
解題說明：
Maintaining the integrity of the Junos OS file system is a critical operational requirement, especially during maintenance that involves removing power from the hardware. To achieve a graceful power-down, the request system halt command must be used. This command initiates a systematic shutdown of all running software processes and daemons, flushes any pending data from the system ' s volatile memory (RAM) to the solid- state storage or hard disk, and unmounts the file systems correctly. Once the software has safely shut down, the console will typically display a message indicating that it is safe to turn off the physical power switch or remove the power cables.
Using request system halt prevents potential file system corruption that can occur if power is abruptly cut while the OS is actively writing logs or configuration data. This is distinct from request system reboot, which restarts the OS, or request system logout, which merely terminates the current CLI session. As a Senior Architect, it is essential to follow this procedure to ensure that the device remains in a reliable state for its next power-on cycle. For devices equipped with dual Routing Engines, the command can often be directed to a specific member or both simultaneously to ensure a synchronized and safe shutdown of the entire chassis.

問題 #100
What does the Junos CLI prompt indicate when it ends with a hash symbol (#)?
答案：D
解題說明：
In Junos OS, a prompt ending with the hash symbol indicates configuration mode, where the user can make and commit configuration changes.
問題 #101
Click the Exhibit button.
Which command displays the output in the format shown in the exhibit?
答案：D
解題說明：
The exhibit illustrates a Junos configuration rendered as a sequence of flat, executable lines that each begin with the set keyword. This is commonly referred to as the " set format. " By default, Junos OS displays the configuration in a hierarchical, brace-delimited format (often called " staza " or " curly brace " format). While the default format is excellent for visualizing the structural relationship between different configuration objects, the set format is often preferred for documentation, scripting, or copying specific configuration snippets between different devices.
To produce the output seen in the exhibit, an administrator must append the pipe filter | display set to the show configuration command. This filter instructs the CLI parser to flatten the hierarchical structure and prepend the necessary context to every individual leaf statement. These lines are highly functional because they can be pasted directly into the CLI of another device while in configuration mode to recreate the exact settings. In contrast, display inheritance is used to reveal hidden settings applied via configuration groups, and display detail provides additional technical metadata about the objects. Neither of those options would transform the output into the discrete set command lines shown in the exhibit. Understanding how to toggle between these display formats is a fundamental skill for any architect managing Junos infrastructures through the Command Line Interface.

問題 #102
Which statement correctly describes the purpose of Class of Service (CoS) in Junos OS?
答案：B
解題說明：
Class of Service enables administrators to classify, prioritize, and manage network traffic differently based on requirements, helping to ensure critical traffic (such as voice or video) receives appropriate treatment during periods of congestion.
