CCNA Subnetting Question with answer: What will be the broadcast IP for the Network 10.1.1.0/24?

As the Network IP address is 10.1.1.0

Second Octet Block Size = 256-255 =1
Third Octet Block Size    = 256-255 =1
Fourth Octet Block Size  = 256-0 = 256

Therefore Subnetwork address will be like this

10.0.0.0 Nw
10.0.0.1
10.0.0.2....255 B
10.0.1.0 Nw
10.0.1.1
10.0.1.2....255 B
10.0.2.0 Nw
10.0.2.1
10.0.2.2....255 B
so on
10.0.255.0 NW
10.0.255.1
10.0.255.2.....255 B
10.1.0.0 Nw
10.1.0.1
10.1.0.2....255 B
10.1.1.0 Nw
10.1.1.1
10.1.1.2....254 Last Valid Host
10.1.1.255------------------- This will be the Broadcast IP address for 10.1.1.0/24
10.1.2.0
