Question 1 of 100

In the show | compare rollback 49 command, what is the purpose of the | ?

The | is used to represent an "either or" statement

The | is a shortcut to redirect output from a command line to a file

The | filters the output of the show command T

The | changes the command from an operational command to a configuration mode command

Correct Answer: C

The pipe character (|) is used to filter or modify the output of a command in many command-line interfaces, including those found in network operating systems like Junos OS. In the command show | compare rollback 49, the pipe filters the output of the show command by sending it to the compare rollback 49 command, which then compares the current configuration with the rollback configuration number 49.

Question 2 of 100

What are two benefits of a modular operating system? (Choose two.)

Each module runs in its own protected memory space

It enables the independent restart of each module as necessary

A malfunction in one module causes a full system shutdown

It enables CPU scheduling strictly using kernel system calls

Correct Answer: A, B

A modular operating system has significant benefits such as: each module runs in its own protected memory space, ensuring that the failure of one module does not affect the others. Additionally, it enables the independent restart of each module as necessary, making it easier to isolate and resolve issues without impacting the entire system.

Question 3 of 100

Referring to the exhibit, you are unable to see any traffic coming on interface ge-0/0/0. What is causing this problem?

The ge-0/0/0 interface is administratively down

The ge-0/0/0 interface has flow control disabled

The ge-0/0/0 interface s physical link is down

The ge-0/0/0 interface has the link-mode set to half-duplex

Correct Answer: C

The ge-0/0/0 interface's physical link is down. This is evident from the line in the output stating 'Physical link is Down'. Even though the interface is administratively enabled and configured correctly with full-duplex mode and a speed of 10Gbps, the physical link being down is preventing any traffic from being seen on the interface.

Question 4 of 100

Which command should you use to check real-time statistics of all active interfaces?

user@router> monitor interface traffic

user@router> show interface detail

user@router> show interface terse

user@router> monitor traffic extensive

Correct Answer: A

To check real-time statistics of all active interfaces, you should use the command 'monitor interface traffic'. This command provides a live display of the traffic data, including the number of packets, bytes, and errors, updating the statistics every second. It is specifically designed to monitor real-time traffic data for all interfaces.

Question 5 of 100

user@router> show interfaces | no-more

What happens when you filter the output of a command using the no-more parameter?

The output is displayed in XML format

The output is displayed with no page breaks

The last screen of information is displayed

The number of lines in the output are displayed

Correct Answer: B

When you filter the output of a command using the no-more parameter in Junos OS, the output is displayed with no page breaks. This means that the output is not displayed one screen at a time, and you can see all the output in a single continuous display.
