Refer to the exhibit. The router has been configured with a super net to accommodate the requirements for 380 users on a Subnet. The requirement already considers 30% future growth. Which configuration verifies the IP subnet on router R4?
A. Subnet: 10.7.54.0 Subnet mask: 255.255.128.0 Broadcast address: 10.5.55.255 Usable IP address range: 10.7.54.1 ג€" 10.7.55.254
B. Subnet: 10.7.54.0 Subnet mask: 255.255.255.0 Broadcast address: 10.7.54.255 Usable IP address range: 10.7.54.1 ג€" 10.7.55.254
C. Subnet: 10.7.54.0 Subnet mask: 255.255.254.0 Broadcast address: 10.7.54.255 Usable IP address range: 10.7.54.1 ג€" 10.7.55.254
D. Subnet: 10.7.54.0 Subnet mask: 255.255.254.0 Broadcast address: 10.7.55.255 Usable IP address range: 10.7.54.1 ג€" 10.7.55.254
Solution
Correct answer: D. Subnet: 10.7.54.0 Subnet mask: 255.255.254.0 Broadcast address: 10.7.55.255 Usable IP address range: 10.7.54.1 ג€" 10.7.55.254.
Subnet Mask: The mask 255.255.254.0 corresponds to a /23 network, which allows 510 usable IP addresses. This is sufficient for 380 users plus a 30% buffer, equating to approximately 494 addresses.
Broadcast Address: The correct broadcast address for the 10.7.54.0/23 network is 10.7.55.255.
Usable IP Range: The usable IP addresses range from 10.7.54.1 to 10.7.55.254.
The other options either have incorrect subnet masks, broadcast addresses, or IP ranges that do not match the requirements.
