Which two actions happen when multiple users issue the configure exclusive command to enter configuration mode on a Junos device? (Choose two.)

1. A. Other users can enter configuration mode.
2. B. The candidate configuration is unlocked.
3. C. The candidate configuration is locked.
4. D. Other users cannot enter configuration mode.

Correct Answer: CD
In Junos OS, when a user issues the configure exclusive command, it locks the candidate configuration for that user, preventing other users from making concurrent configuration changes. This exclusive lock ensures that configuration changes are managed in a controlled manner, reducing the risk of conflicting changes. As a result, while one user is in exclusive configuration mode, other users are prevented from entering configuration mode until the lock is released, either by the user committing the changes or exiting configuration mode.

Click the Exhibit button.

Referring the exhibit, what does the highlighted number indicate?

1. A. route preference is 5
2. B. hop count is 5
3. C. cost is 5
4. D. metric is 5

Correct Answer: A
In the exhibit shown, the highlighted number next to the route type (Static) within the square brackets indicates the route preference, also known as the administrative distance. In Junos, the route preference is a value that determines the priority of the route source. Lower numbers indicate a higher priority when the routing table is being calculated. The route preference is used to select the best route when multiple paths to the same destination exist from different routing sources. The number 5 is unusually low for a static route by default, suggesting it has been manually configured to override other route types.

Which criteria does the Junos OS use to select an active route when two entries exist in the routing table?

1. A. the route with the lowest preference number
2. B. the most recently learned dynamic route
3. C. the route with the highest preference number
4. D. the route with the highest metric

Correct Answer: A
In Junos OS, when two entries for the same destination exist in the routing table, the route with the lowest preference number is selected as the active route. This preference number, also known as the route preference or administrative distance, is used to prioritize routes received from different routing protocols.

You issue the telnet 10.10.10.1 source 192.168.100.1 command. Which two statements are correct in this scenario? (Choose two.)

1. A. The telnet session will have a source address of 10.10.10.1.
2. B. The telnet session will have a destination address of 192.168.100.1.
3. C. The telnet session will have a destination address of 10.10.10.1.
4. D. The telnet session will have a source address of 192.168.100.1.

Correct Answer: CD
In the given telnet command, "telnet 10.10.10.1 source 192.168.100.1," the destination address of the telnet session is 10.10.10.1, and the source address of the session is specified as 192.168.100.1, making C and D the correct answers. This command instructs the telnet client to use the specified source IP address when establishing the connection to the destination.

You have logged on to a Junos device and are at the operational mode prompt. Which two commands are used at this prompt? (Choose two.)

1. A. show interface ge-0/0/0
2. B. request system shutdown
3. C. set interface ge-0/0/0 unit 0 family inet
4. D. run show interface terse

Correct Answer: A
At the operational mode prompt on a Junos device, you can use various commands to view the device's status and request system operations. The show interface ge-0/0/0 command is used to display information about a specific interface, while the request system shutdown command is used to properly shut down the device. The set command is used in configuration mode, not operational mode, and the run command is used to execute operational mode commands from configuration mode.
