Q19IP Connectivity
A network engineer must configure an interface with IP address `10.10.10.145` and a subnet mask equivalent to `11111111.11111111.11111111.11111000`. Which subnet mask should the engineer use?

The subnet mask equivalent to 11111111.11111111.11111111.11111000 in dotted decimal notation is 255.255.255.248.
To figure out the right subnet mask for the given IP address and subnet mask, we need to find the number of bits in the network portion of the address.
In this case, the first 29 bits of the IP address are used for the network portion, and the remaining 3 bits are used for the host portion. Therefore, the correct subnet mask is /29.

/29 just calculate or add the number of bits

Selected Answer: A
11111000 = /29 in the last octet

Selected Answer: A
Block size >>128 (on) /25, block size>> 64 (on) /26, block size>> 32 (on) /27, block size>> 16 (on) /28, block size>> 8 (off) /29...Block size 8 /29 is your answer. Easy subnetting
A 1
Selected Answer: A
It's leaving three bits for the host, meaning the last 3 zeroes. 2^3=8. 32-8=29
A 1
Selected Answer: A
best way to count, full octet minus count of 0s.
In this case 32 - 3 = 29
A 1
Selected Answer: A
Count the number of 1's and that gives the answer.
