The question is asking you to identify three components that would improve network availability for users on a campus network with routed access, given a limited budget. Let's examine each option:
A. Redundant power supplies in the access routers: This option provides power redundancy in the access layer of the network, which can help ensure that network devices remain powered in the event of a power outage or failure of a power supply. While this is a useful feature, it does not directly improve network availability or address potential network failures.
B. Standby route processors for SSO in the core routers: This option provides standby route processors for Stateful Switchover (SSO) in the core routers. SSO is a feature that allows a router to quickly switch to a standby route processor in the event of a failure, minimizing disruption to network traffic. This is a useful feature that can improve network availability.
C. Standby route processors for SSO in the distribution routers: This option provides standby route processors for SSO in the distribution layer of the network. As with option B, this can improve network availability by allowing for quick failover in the event of a failure.
D. Standby route processors for SSO in the access routers: This option provides standby route processors for SSO in the access layer of the network. While this can provide some redundancy in the access layer, it is generally less critical than redundancy in the core or distribution layers.
E. Replace copper links between devices with fiber links: This option replaces copper links between network devices with fiber links. While this can provide some benefits, such as improved speed and distance, it does not directly improve network availability or address potential network failures.
Based on the above analysis, the three components that would be most beneficial for improving network availability in a campus network with routed access are:
These options provide redundancy and failover capabilities in critical areas of the network, helping to ensure that network traffic can continue to flow in the event of a failure.
