You need to configure interface ge-0/1/2 with an IP address of 172.16.100.1/24. You have accidentally entered 172.16.101.1/24 as shown in the exhibit.
Which command should you issue to solve the problem?
Correct Answer:
A
If you've committed a configuration and then need to revert to the previous configuration, the rollback command is used. Since the incorrect IP address has not been committed, as indicated by the commit check command being successful, issuing rollback 1 will undo the changes made in the current session, which includes the accidental entry of the IP address.
An administrator configures a router's interface with an IPv4 address and subnet mask. The administrator also confirms that this interface is in an up state.
In this scenario, which two route types are created on the local router? (Choose two.)
Correct Answer:
BD
When an interface on a router is configured with an IPv4 address and is in an up state, two types of routes are automatically created in the routing table: a local route and a direct route, making B and D the correct answers. The local route represents the interface's IP address itself, indicating that the router can directly receive packets addressed to this IP. The direct route represents the subnet or network segment to which the interface is connected, indicating that the router can directly forward packets to destinations within this subnet.
You received a new Junos device and are configuring the system-related settings. You must configure this device for the current date and time on the US West coast. You have set the time zone to America/Los_Angeies. however the time and date did not change.
In this scenario, which two additional actions would satisfy this requirement? (Choose two.)
Correct Answer:
AB
When configuring the system-related settings for the current date and time on a Junos device, especially for a specific time zone like America/Los_Angeles, and the time does not automatically adjust, two effective actions can be taken. Firstly, setting the date and time manually allows for immediate correction of the system clock. This can be done via the CLI with the appropriate set date and time command. Secondly, configuring the device to use an NTP server can provide ongoing synchronization with an accurate time source, ensuring that the device maintains the correct time and date automatically in the future, even in the case of restarts or minor drifts in the internal clock.
You are asked to convert the number 7 from decimal to binary. Which number is correct in this scenario?
Correct Answer:
C
To convert the decimal number 7 to binary, the correct representation is 00000111 (C). In binary, 7 is represented as 1+2+4 (2^0 + 2^1 + 2^2), which corresponds to the last three digits being 1 in the binary format, with leading zeros added for clarity.
You want to redeploy a Junos device by clearing the existing configuration and resetting it to factory defaults.
In this scenario, which command would help to accomplish this task?
Correct Answer:
D
The request system zeroize media command on a Junos device securely erases all data, including configuration and log files, and resets the device to its factory default settings. This command is used when redeploying a device to ensure no residual data remains from its previous deployment. It's a comprehensive and secure way to clear all configurations and data, making the device as if it were new. The other commands listed do not perform a full reset to factory defaults; for example, show system storage displays storage information, and request system storage cleanup offers to delete unnecessary files without resetting the device to factory settings.
