Question 1 of 96

Which command verifies configuration syntax without applying the changes?

commit confirmed

commit check

commit comment

commit and-quit

Correct Answer: B

The command 'commit check' verifies the configuration syntax without applying the changes. This command checks the syntax for any potential errors or issues, ensuring that the configuration is valid before any changes are actually committed. This helps in preventing incorrect configurations from being applied.

Question 3 of 96

You are considering an upgrade from 19.1R1 and want to ensure that only bug fixes are included.

Which two software versions should you consider in this situation? (Choose two.)

19.3R1-S1

19.3R2

19.1R3

19.1R1-S2

Correct Answer: A, C

To ensure that only bug fixes are included, you should focus on maintenance releases within the same major version. Versions like 19.1R3 and 19.1R1-S2 are designed to provide ongoing bug fixes without introducing new features. Maintenance releases (e.g., the R3 in 19.1R3) and spin releases (e.g., the S2 in 19.1R1-S2) are intended to address specific issues and provide stability improvements.

Question 4 of 96

Which two statements are true about static routes in the Junos OS? (Choose two.)

Static routes remain in the routing table until you remove them or until they become inactive.

Static routes must have a next hop defined.

Static routes are learned by neighboring devices and added to their routing tables.

Static routes are defined at the [edit routing-instances] hierarchy.

Correct Answer: A, B

Static routes remain in the routing table until you remove them or until they become inactive, ensuring persistent routing decisions based on predefined criteria. Additionally, static routes must have a next hop defined to specify where packets should be forwarded for a particular destination, as this is crucial for proper routing function.

Question 5 of 96

When multiple users are editing the configuration on a Junos device, what is the default behavior when a user issues a commit command?

All valid configuration changes made by all users will take effect.

The user's configuration changes are committed; other users' configuration changes are still pending.

The user will receive an error message disallowing a commit of the configuration.

The user's configuration changes are committed; other users will be exited from configuration mode.

Correct Answer: B

When multiple users are editing the configuration on a Junos device and a user issues a commit command, only that user's configuration changes are committed. The configuration changes made by other users remain pending. The default behavior ensures that each user's changes are handled independently to prevent conflicts and maintain the integrity of the configuration process.
