Exhibit

Exhibit
[edit]
root# set system host-name TEST_DEVICE [edit]
root# commit
[edit]
'system'
Missing mandatory statement: 'root-authentication' error: commit failed: (missing mandatory statements) [edit] root#

You are configuring a new device.
Which action solves the error shown in the exhibit?

  1. configuring a non-root username and password
  2. configuring a password for the root account
  3. loading the factory-default configuration
  4. reinstalling Junos

Answer(s): B

Explanation:

The error message in the exhibit indicates that the root-authentication statement is missing, which is mandatory for committing the configuration. In Junos OS, it is required to set a password for the root account to commit any configuration changes. This is a security measure to ensure that unauthorized users cannot access the device's configuration mode. To solve the error shown in the exhibit, configuring a password for the root account is necessary. This can be done by using the set system root-authentication plain-text-password command, after which the user will be prompted to enter a new password for the root account.



Exhibit user@router> show route 192.168.100.2
inet.O: 15 destinations, 17 routes (15 active, 0 holddown, 0 hidden) Limit/Threshold:
1048576/1048576 destinations
+ = Active Route, - = Last Active, * = Both 192.168.100.2/32 *[OSPF/IO] 00:14:29, metric 1 > to 172.16.1.6 via ge-0/0/1.0 [BGP/170] 00:06:49, localpref 100 AS path: 65102 I, validation-state: unverified > to 172.16.1.6 via ge-0/0/1.0

Referring to the exhibit, which statement is correct?

  1. The BGP path is the only active route.
  2. The BGP route is preferred over the OSPF route.
  3. The OSPF path is the only active route.
  4. / Traffic is load-balanced across two routes.

Answer(s): C

Explanation:

Referring to the exhibit, the presence of the "+" symbol next to the OSPF route for 192.168.100.2/32 indicates that this is the active route being used to forward traffic. The BGP route, although present, does not have the "+" symbol, indicating it is not the active route. In Junos OS, the routing table displays the active route with a "+" symbol, and the fact that the OSPF route has this symbol means it is the preferred path based on the routing protocol's decision process, which takes into account factors such as route preference (administrative distance) and metrics.



Exhibit
[edit system archival] user@router# show configuration { transfer-on-commit; archive-sites {
"scp://user@172.15.100.2 : /archive" password ## SECRET-DATA "ftp://user@10.210.9.178:/archive" password "$9..."; ## SECRET-DATA

Referring to the exhibit, where are the configuration backup files stored?

  1. Files are stored to the SCP site and the FTP site in a round-robin manner.
  2. Files are stored to the SCP site and the FTP site simultaneously.
  3. Files are stored to any site as selected by Junos internally.
  4. Files are stored to the SCP site but if the transfer fails, then to the FTP site.

Answer(s): B

Explanation:

In Junos OS, the archival configuration under [edit system] allows for the automatic backup of configuration files to designated locations upon commit.
When multiple archive-sites are specified, as shown in the exhibit with both SCP and FTP sites listed, the device does not choose between them or use them in a round-robin manner. Instead, it attempts to transfer the configuration backup files to all specified sites simultaneously upon each commit. This ensures redundancy and increases the likelihood that a backup will be successfully stored even if one of the transfer methods or destinations fails.



You want to find out the chassis serial number of a Junos device.
Which command would display this information?

  1. show chassis environment
  2. show chassis hardware
  3. show chassis routing-engine
  4. show chassis location

Answer(s): B

Explanation:

The show chassis hardware command in Junos OS displays detailed information about the hardware installed in the device, including the chassis itself. This command provides a list of all hardware components, their serial numbers, part numbers, and version information.
When looking for the chassis serial number specifically, this command is the most direct and comprehensive way to retrieve that information, as it includes the serial number of the chassis among the details provided.
