  1. 64
  2. 62
  3. 30
  4. 14
Explanation
Answer: B - A maximum of 62 hosts can reside on a subnet with subnet mask 255.255.255.192.

Key Takeaway: A subnet mask of 255.255.255.192 indicates a Class C network. The last octet being 192 indicates that 2 bits among the 8 are part of the network ID. This means 6 bits are used to identify the subnet. With 6 bits, the maximum number of hosts that are a part of the subnet is 26 − 2 = 62.
