Refer to the exhibits.
Exhibit 1.
Exhibit 2.
The exhibits show the current operational state for routes on Switch-3. The company wants Switch-3 to prefer the link to Switch-1 over the link to Switch-2 for all intra-area, inter-area, and external traffic.
What can the network administrator do to achieve this goal?
To ensure Switch-3 prefers the link to Switch-1 over the link to Switch-2 for intra-area, inter-area, and external traffic, the network administrator should adjust the OSPF cost on the relevant VLANs. Setting the OSPF cost on VLAN 108 higher than 1 on Switch-2 and Switch-3 will increase the cost associated with the route through Switch-2. This change will make the route through Switch-1 the preferred path, as OSPF will select the route with the lower cost.
Answer is A.
