Answer

Suggested Answer

The suggested answer is 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.

The suggested answer is 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.

Question 3 of 103
Exam JN0-104: Question 3 - Image 1
Referring to the exhibit, you are unable to see any traffic coming on interface ge-0/0/0. What is causing this problem?
Answer

Suggested Answer

The suggested answer is 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.
