Question 2

What is the purpose of 'route distinguishers' (RDs) in MPLS Layer 3 VPNs?

Accepted Answer

Make overlapping customer IP prefixes unique in the BGP table

Question 3

Which Cisco IOS feature allows traffic to be directed to a service (such as a firewall) transparently before forwarding, based on a policy map?

Accepted Answer

Policy-Based Routing (PBR)

Answer

Policy-Based Routing (PBR) uses route-maps to forward traffic based on match criteria (source IP, protocol, port) rather than the routing table destination.

Question 4

A wireless engineer notices that 5 GHz clients are connecting to 2.4 GHz due to strong RSSI. Which feature should be enabled to push capable clients to 5 GHz?

Accepted Answer

Band steering

Answer

Band steering monitors client probes and discourages dual-band clients from associating to the more-congested 2.4 GHz band, steering them toward 5 GHz.

Question 5

Which field in the IP header does DSCP marking use to classify traffic for QoS?

Accepted Answer

ToS byte (DSCP bits)
