The exhibit shows the output of the command show ip bgp, which displays information about the BGP routes in the routing table. The output shows two routes for the destination 192.168.10.0/24, one from R1 and one from R2.
The route from R1 has a local preference of 200, while the route from R2 has a local preference of 100. Local preference is a BGP attribute that indicates the degree of preference for a route within an autonomous system (AS). A higher local preference means a more preferred route.
BGP uses a best path selection algorithm to choose the best route for each destination among multiple paths. The algorithm compares different attributes of the routes in a specific order of precedence. The first attribute that is compared is weight, which is a Cisco-specific attribute that is local to the router. If the weight is equal or not set, the next attribute that is compared is local preference.
In this case, both routes have the same weight of 0, which means that they are learned from external BGP (eBGP) peers. Therefore, the next attribute that is compared is local preference.
Since R1's route has a higher local preference than R2's route, it is chosen as the best path and installed in the routing table. The other attributes, such as origin code and AS path, are not considered in this case.

A is correct because RSTP alternate ports block traffic while receiving superior BPDUs from a neighboring switch. An alternate port is a backup port for a root port, which means it receives better BPDUs from another bridge than the current root port. However, an alternate port does not forward any traffic, as it is in a discarding state. It only listens to BPDUs and waits for the root port to fail. If the root port fails, the alternate port can immediately transition to a forwarding state and become the new root port.
C is correct because RSTP alternate ports provide an alternate higher cost path to the root bridge. An alternate port is selected based on the same criteria as the root port, which are the lowest bridge ID, the lowest path cost, the lowest sender port ID, and the lowest receiver port ID.
However, an alternate port receives a higher cost BPDU than the root port, otherwise it would be the root port itself. Therefore, an alternate port provides an alternate higher cost path to the root bridge than the root port.

In BGP, the path selection process is based on a set of attributes. The process starts by preferring the path with the highest weight, then the highest local preference, then the locally originated routes, and so on. If all these attributes are the same, then it prefers the path with the shortest AS path.
Referring to the exhibit, all four ISPs have the same weight, local preference, and origin.
However, ISP 4 has the shortest AS path. Therefore, ISP 4 will be selected as the active path.
So, option C is correct.
