You need to configure a server that is on the subnet The router has the first available host address. Which of the following should you assign to the server?
Answer: Option
A /29 is, which is a block size of 8 in the fourth octet. The subnets are 0, 8, 16, 24, 32, 40, etc. is the 24 subnet, and since 32 is the next subnet, the broadcast address for the 24 subnet is 31. is the only correct answer.

C is the correct answer because the first available host has been assigned to the router and 2nd available host can be assigned to server.
So, the correct answer is C

As I solved this question :

Nework id :-
First vaild host :-
Last vaild host -
Broadcost IP address :-
Subnet mask :-

Please check it.

The first host address should be :

Because up to 29 bits it is fixed part and the remaining part is 3 bits. -> subnet block id.
.00011001-> this will be the first host for this subnet.

I think here first usable host is Because here is the network address.

First host address is assigned to the router as said in the question, after that next available address is (as given in options) which would assign to the server.

I think it the range coming in to

So the 1st host coming is

Please check it.

I think answer is (D).


Given CIDR is which means the NID is 29 bits and HID is 3 bits.

So the subnet mask becomes

Given that the router has the first available host address (i.e, SubnetID), which is given by:

( AND ( =, which is the IP address of the router.

We know that =

Here the NID part is (29 bits) and host id part is remaining 3 bits.

In order to get the broadcast address (address of the server), set all host id bits to 1. Then it becomes

i.e, which is the IP address of the server.
