Exam JN0-104 topic 1 question 79 discussion

Monitor traffic interface ge-0/0/0 only give specific interface statistics, Monitor interface traffic give all interface usages

he correct command to provide real-time usage statistics for the ge-0/0/0 interface in Junos operational mode is: B. monitor interface traffic This command will display real-time statistics for the specified interface, including traffic rates, packets, errors, and other related information.

B is the right answer

Outputs from real devices: monitor interface traffic <-real-time statstics from all interfaces (can be specified for one interface) DistributionSwitch Seconds: 27 Time: 10:40:52 Interface Link Input packets (pps) Output packets (pps) xe-0/0/0 Up 24866382907 (6692) 38405799606 (12162) xe-0/0/1 Up 26960064415 (7003) 39793158629 (10024) monitor traffic interface xe-0/0/0 <-monitors individual packets verbose output suppressed, use <detail> or <extensive> for full protocol decode Address resolution is ON. Use <no-resolve> to avoid any reverse lookup delay. Address resolution timeout is 4s. Listening on xe-0/0/0, capture size 96 bytes 10:37:49.430342 Out [|LLDP] 10:37:50.916334 In [|LLDP]

correct: B please check the documentation: https://www.juniper.net/documentation/us/en/software/junos/interfaces-ethernet-switches/icmp/topics/ref/command/monitor-interface.html https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/ref/command/monitor-traffic.html

They ask for real-time usage NOT real-time traffic (packets). B is correct

monitor interface traffic Bytes=b, Clear=c, Delta=d, Packets=p, Quit=q or ESC, Rate=r, Up=^U, Down=^D Interface Link Input packets (pps) Output packets (pps) gr-0/0/0 Up 0 (0) 0 (0) pfh-0/0/0 Up 0 0 xe-0/0/0 Up 0 (0) 0 (0) xe-0/0/1 Up 0 (0) 0 (0)

This command works with vSRX https://www.youtube.com/watch?v=0Fxu8hGbTbw&ab_channel=RAYKA

monitor interface ge-0/0/0 command which allows you to view interface usage details in real time, how much data is coming in, going out.etc monitor interface traffic which does something similar but gives you one line per interface, maybe useful if you’re looking at how much total data is going through a switch and which ports are most active? https://alexwilkins.dev/index.php/junos-ops-and-monitoring/

B doesnt let you specify an interface

Looks like B is correct. In A you can see a traffic capture, but B shows real-time statistics.

shouldn't be A?
