Exhibit

[edit]

user@routerl set interfaces ge-0/1/2 unit 0 family inet address 172.16.101.1/24 [edit]

user@router# commit check

configuration check succeeds

[edit]

user@router#

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.

[edit] user@routeri rollback rescue
Answers
Suggested answer: A

Explanation:

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.

D.
It activates the rescue configuration.
Answers
Suggested answer: A

Explanation:

The request system configuration rescue save command in Junos OS saves the most recently committed configuration as the rescue configuration. This rescue configuration can be used to recover the device if future configurations cause issues. It ensures there is a stable, known-good configuration to fall back on, which is crucial in network management and troubleshooting.

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.)

Answers
D.
a direct route
D.
a direct route
Answers
Suggested answer: B, D

Explanation:

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.

Suggested answer: C, D

Explanation:

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.

Answers
Suggested answer: A

Explanation:

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.

D.
Routing tables are stored in the forwarding plane.
D.
Routing tables are stored in the forwarding plane.
Answers
Suggested answer: A, C

Explanation:

In Junos OS, as with many network operating systems, the control plane is responsible for processes that determine how to route traffic. This includes maintaining routing tables, which store information about network paths and protocols. Therefore, routing tables are indeed stored in the control plane.

Exception traffic refers to packets that cannot be processed by the normal fast-path processing of the Packet Forwarding Engine (PFE) in the forwarding plane, and thus are sent to the control plane for further processing. This might include packets destined for the router itself, packets that need to be fragmented, or packets that match certain firewall filter criteria, among other reasons.

Routing tables are not stored in the forwarding plane. However, the forwarding plane contains the forwarding table (sometimes referred to as the forwarding information base or FIB), which is a distilled version of the routing table optimized for fast packet forwarding. The forwarding plane uses this information to perform the actual transfer of packets across the network device interfaces.
