Routing Table and Equal-Cost Routes:When multiple routes to the same destination network have the same cost (e.g., metric or administrative distance), they are referred to as " equal-cost routes. " Routers use load balancing to distribute traffic across these routes​​.

Analysis of Options:

Option A: " Sub-optimal routes " are routes that are not preferred due to higher cost or less desirable metrics.

Option B: " Multipath routes " is a general term but does not specify equal cost, making it less precise.

Option C: " Equal-cost routes " is correct as the scenario specifies the same destination network with the same cost.

Option D: " Default routes " are used when no specific route matches the destination, which is unrelated to the given scenario​.

Correct Answer:The routes are C (Equal-cost routes).

Detailed Explanation:The 802.11ax standard, also known as Wi-Fi 6, supports theoretical speeds over 5 Gbit/s and is designed for high-efficiency wireless networking in dense environments. (Reference: HCIA-WLAN Training Material, IEEE 802.11 Standards)

Detailed Explanation:Small campus networks are characterized by simple architecture, limited user counts, and straightforward network requirements. Wide coverage is typically associated with larger campus or enterprise networks. (Reference: HCIA-Datacom Training Material, Campus Network Characteristics)

In the IP header at the network layer, the Protocol field specifies the transport layer protocol in use. The protocol number for UDP is 17, not 6. Protocol number 6 is reserved for TCP. This field allows IP packets to be correctly processed by the appropriate transport-layer protocol at the receiving device​.
