Question
View the exhibit. Area 1 and Area 2 in the topology are associated with/21 subnets, shown in Exhibit 1. All of the switches in this topology are HP Provision ASIC switches, and they have established the appropriate adjacencies. In Area 1, one of the/24 subnets within the/21 range, 10.1.19.0/24, is not used. The network administrator must prevent unnecessary traffic from entering Area 1 if users attempt to reach an address in the unused range. What can the administrator do that meets this requirement without disrupting the solution? HP HP0-Y43 Exam
