Explanation
52)A /29 that s 255.255.255.248 has a block size of eight in the 4thoctet. This means the subnets are 0,8,16,24and so 10 is in the 8 subnet. The next subnet is 16,

Therefore 15 is the broadcast address.

62)

We need to use the formula

2^hostid-2

2¹⁶-2

65536-2

65534

---
67)
A /27 that is 255.255.255.224 is three bits on and five bits off. This provides eight subnets, each with thirty hosts. The number of host bits would never change.

Therefore 30 is the correct answer
