Refer to the exhibit. The internetwork is using subnets of the address 192.168.1.0 with a subnet mask of 255.255.255.224. The routing protocol in use is RIP version 1.
Which address could be assigned to the FastEthernet interface on RouterA?
A. 192.168.1.31
B. 192.168.1.64
C. 192.168.1.127
D. 192.168.1.190
E. 192.168.1.192
Answer: D
Explanation:
Subnet mask 255.255.255.224 with CIDR of /27 which results in 32 hosts per.
192.168.1.31 is the broadcast address for sunbet ‘0’ 192.168.1.64 is the network address for subnet ‘2’ 192.168.1.127 is the broadcast address for subnet ‘3’ 192.168.1.192 is the network address for subnet ‘6’
why isnt the answer also B? both .64 and .192 are possible network address for a /27 subnet
Because it is a subnet ID. Only D can be assigned to an interface.
FYI: RIPv1 is a is a Classful routing protocol, it cannot handle subnetting – this question is mistaken using VLSM
VLSM should use more than one mask, but this network only use one mask. So I think question is fine.
