Host 1 configuration: | Host 2 configuration:IP Address: 10.1.32.48 | IP Address: 10.1.40.96 Mask: 255.255.240.0 | Mask: 255.255.252.0 Gateway: 10.1.32.45 | Gateway: 10.1.40.255
Host 1 can not receive packets from Host 2. Assuming that RIP v1 is the routing protocol in use. What is wrong with the IP configuration information shown? (Choose two)
A. The fa0/1 interface of router R2 has been assigned a broadcast address.
B. The fa0/1 network on router R2 overlaps with the LAN attached to R1.
C. Host 2 has been assigned the incorrect subnet mask.
D. Host 1 has been configured with the 255.255.248.0 subnet mask.
E. Host 2 on router R2 is on a different subnet than its gateway.
Correct Answer: BC QUESTION 8
S0/0 on R1 is configured as a multipoint interface to communicate with R2 and R3 in the hub-and-spoke
Frame Relay topology.
While testing this configuration, a technician notes that pings are successfully from hosts on the
172.16.1.0/24 network to hosts on both the 172.16.2.0/25 and 172.16.2.128/25 networks.
However, pings between hosts on the 172.16.2.0/25 and 172.16.2.128/25 network are not successful.
What could explain this connectivity problem?
A. The ip subnet-zero command has been issued on the R1 router.
B. The RIPv2 dynamic routing protocol cannot be used across a Frame Relay network.
C. Split horizon is preventing R2 from learning about the R3 networks and R3 from learning about R2 networks.
D. The 172.16.2.0/25 and 172.16.2.128/25 networks are overlapping networks that can be seen by R1, but not between R2 and R3.
E. The 172.16.3.0/29 network used on the Frame Relay links is creating a discontiguous network between the R2 and R3 router subnetworks.
Correct Answer: C
