There will only be route B in the routing table of this router because dynamic routing takes precedence

There is only route A in the routing table of this router because route A has a high priority.

The next hop interface of the route with the destination network segment 8.8.8.8/32 is InLoop0, indicating that the next hop of the route is a virtual interface similar to Null0, and the route is a black hole route.

The router is running RIPv1 because the mask of the destination network segment 30.0.0.0 is a natural mask.

This routing table is not the complete routing table of the router. The complete routing table should at least have the directly connected network segment route of interface GE0/0.

138. The customer’s network connection looks like:

142. An empty-configured MSR router connects to local LAN users through the GE0/0 interface and directly connects to the remote router through the S1/0 interface. The IP addresses of the GE0/0 interface and the S1/0 interface are 10.1.1.1/24 and 172.16.1.1/30 respectively.

In order to ensure intercommunication with remote LAN users, the following routes are configured on the MSR:

[MSR] ip route 10.20.0.0 255.255.255.0 s1/0

After configuration, MSR receives a data packet sent to the destination address 10.20.0.254/24. After finding the static route in the routing table, how will MSR process the data packet next?

Drop the packet because the destination host is not listed in the routing table

Drop the packet because the next hop address is not listed in the routing table

Encapsulate the IP packet into a frame that conforms to the S1/0 interface link, and then forward it out from the S1/0 interface.

Analyze the MAC address of the S1/0 interface, update the destination MAC address, and then re-encapsulate the IP packet.

Find the IP address corresponding to interface S1/0, and then forward the IP packet from interface S1/0

143. Assume that an MSR router obtains two routes to the destination network segment 100.120.10.0/24. The costs of these two routes are 120 and 10 respectively, and the priorities are 10 and 150 respectively.

Prioritize matching of routes with Cost 120

Prioritize matching of routes with Cost 10

Prioritize matching of routes with priority 10

Prioritize matching of routes with priority 150

144. Router MSR-1 is interconnected with MSR-2 and MSR-3 respectively. In the routing table of MSR-1, there is a RIP route learned from MSR-2 to the destination network segment 120.10.12.0/24. Its Cost is 3; at this time, MSR-1 also receives a RIP route from MSR-3 that is still destined for the destination network segment 120.10.12.0/24, and its Cost is 15, then ______.

The routing table of MSR-1 will not be updated, and the routes for this network segment learned from MSR-2 will still be retained.

The routing table of MSR-1 will be updated to the route with a cost of 15 learned from MSR-3.

The routing table of MSR-1 will be updated because the RIP route with Cost 15 means that there may be a loop in the network.

The routing table of MSR-1 will not be updated because a RIP route with a Cost of 15 means an unreliable route and RIP will not write it into its own routing table.

145. How does RIP avoid routing loops by combining suppression time and route poisoning?

After learning a route from an interface, set the metric value of the route to infinity and send it back to the neighbor router from the original interface.

After learning a route from an interface, set the suppression time for the route and send it back to the neighbor router from the original interface.

Actively set the suppression time for the route of the faulty network segment, set its metric value to infinity, and send it to other neighbors.

After learning a route from an interface, set the metric value of the route to infinity and set the suppression time, and then send it back to the neighbor router from the original interface.
