Question #: 7
Topic #: 1
Refer to the exhibit. The router has been configured with a supernet to accommodate the requirement for 380 users on a subnet. The requirement already considers 30% future growth. Which configuration verifies the IP subnet on router R4?
To accommodate 380 users plus 30% future growth (494 total users), a subnet must have at least 512 usable IP addresses. A subnet mask of 255.255.254.0 (/23) provides 510 usable host addresses (2,048 - 2 = 510), fitting the requirement. The correct configuration reflects this, with a usable range from 10.7.54.1 to 10.7.55.254 and a broadcast address of 10.7.55.255.
