Option ‘a’ is not in scope (10.10.1.0 10.10.1.15) ☹
Option ‘b is in scope to 30-bits (10.10.1.20 10.10.1.23) 😊
Option ‘c’ is not is scope (10.10.1.16 10.10.1.19) ☹
Option ‘d’ is not is scope (10.10.1.20 10.10.1.21) ☹
The correct answer is Option ‘b’.
We will use the longest prefix match inclusive of the destination address. Option B with a subnet mask of /30 will have 4 IP addresses (2 usable IPs)
10.10.1.20 --- 10.10.1.23
Option D has no usable IPs
options A and C don't include 10.10.20.22
This is B for example:
GROUP SIZE: 128 64 32 16 8 [ 4 ] 2 1
SUBNET: 128 192 224 240 248 [ 252 ] 254 255
CIDR: /25 /26 /27 /28 /29 [ /30 ] /31 /32
10.10.1.20
Group size is 4. Start at 0 and go up by 4. 4, 8, 12, 16, 20, 24.
We land on 20 so that's the network.
Notice I continued to .24 instead of stopping at .20.
.24 is the next subnet.
.23 is the broadcast.
.22 is the last usable host.
.21 is the first usable.
.20 is the network.
- the destined ip address is 10.10.1.22
A- the range is 10.10.1.0 to 10.10.1.15 --> wrong range
B- the range is 10.10.1.20 to 10.10.1.23 --> right range
C- the range is 10.10.1.16 to 10.10.1.19 --> wrong range
D- the range is 10.10.1.20 to 10.10.1.21 --> wrong range
So the only correct range is answer B, so B is the correct answer
if there are more than 1 correct range, then the correct answer will be the range with the longer prefix.
Router(config-if)#ip address 192.168.0.1 255.255.255.254
Bad mask /31 for address 192.168.0.1
.254 is broadcast address for /31 not valid
the longest prefix here is .252 /30
It's using the longest match rule. IE, the longest subnet will be routed first. 255.255.255.254 is /30, which is longer than any of the other ranges that still include the target address.
