NEW QUESTION 185
Two empty-configured MSR routers RTA and RTB are interconnected back-to-back through their Serial1/0 interfaces. Do the following configuration on the two routers:
RTA: skip
[RouterA-Serial1/0] link-protocol fr ietf
[RouterA-Serial1/0] ip address 10.1.1.1 30
[RouterA-Seria11/0] fr map ip 10.1.1.2 30
RTB: [RouterB-Serial1/0] link-protocol fr ietf
[RouterB-Serial1/0] interface serial0/0.1
[RouterB-Serial1/0.1] ip address 10.1.1.2 30
[RouterB-Serial1/0.1] fr map ip 10.1.1.1 30
The physical link between the routers is good, so the correct statement below is ______. (Multiple choice)

DLCI is not configured on the two routers, and RTB cannot be pinged on RTA

Can’t ping 10.1.1.2 on RTA

You can ping 10.1.1.2 on RTA

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then you cannot ping 10.1.1.2 on RTA.

In the above configuration, if you only change the type of sub-interface serial0/0.1 on RTB to P2MP, then you can ping 10.1.1.2 on RTA

NEW QUESTION 186
The routing table seen on an MSR router is as follows:
Destination/Mask Proto Pre Cost NextHop Interface
6.6.6.0/24 Static 60 0 100.1.1.1 GE0/0
8.8.8.8/32 Direct 0 0 127.0.0.1 InLoop0
20.1.1.0/24 Static 60 0 100.1.1.1 GE0/0
30.0.0.0/8 RIP 100 1 100.1.1.1 GE0/0
Then the correct analysis of this routing table is ______.

The IP address of GE0/0 on the router is 100.1.1.1

The next hop interface of the route whose destination network segment is 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

The routing table is not the complete routing table of the router, and the complete routing table should have at least the direct network segment route of interface GE0/0
