Exhibit
user@router> show route 192.168.36.1
inet.O: 5 destinations, 6 routes (5 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both
192.168.36.1/32 *[Static/5] 00:00:31
> to 10.1.1.2 via ge-0/0/10.0 [OSPF/IO] 00:02:21, metric 1 > to 10.1.1.2 via ge-0/0/10.0
Referring to the exhibit, which route(s) will be selected by Junos for packet forwarding?
Junos OS selects routes based on the route preference (also known as administrative distance). Static routes typically have a lower route preference than OSPF routes, meaning they are more preferred. Since the static route to 192.168.36.1/32 is shown with a preference of 5, it will be selected over the OSPF route for packet forwarding, assuming no other factors such as route filters or policies affect the routing decision.
What is a benefit of using J-Web?
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.
Which statement is correct when multiple users are configuring a Junos device using the configure private command?
When multiple users are configuring a Junos device using the 'configure private' command, each user gets their own candidate configuration (C). This allows for isolated configuration sessions, where changes made by one user do not impact or interfere with the changes made by another user in their private session.
Which protocol is responsible for learning an IPv4 neighbor's MAC address?
The Address Resolution Protocol (ARP) is a fundamental protocol used in IPv4 networking to map an IP address to its corresponding MAC (Media Access Control) address. When an IPv4 device wants to communicate with another device on the same local network, it uses ARP to find out the MAC address associated with the target device's IP address. This ensures that IP packets can be encapsulated into Ethernet frames and delivered to the correct hardware address on the local network segment. ARP does not apply to IPv6, where Neighbor Discovery Protocol (NDP) performs a similar function.
Which statement is correct when multiple users are configuring a Junos device using the configure private command?
When multiple users are configuring a Junos device using the 'configure private' command, each user gets their own candidate configuration (C). This allows for isolated configuration sessions, where changes made by one user do not impact or interfere with the changes made by another user in their private session.
