Demo Questions
Question 1
After a redundant route processor failure occurs on a Layer 3 device, which mechanism allows for packets to be forwarded from a neighboring router based on the most recent tables?
- RPVST+
- RP failover
- BFD
- NSF
Correct answer: D
Question 2
What is the differences between TCAM and the MAC address table?
- Router prefix lookups happens in CAM. MAC address table lookups happen in TCAM
- The MAC address table supports partial matches. TCAM requires an exact match
- The MAC address table is contained in CAM. ACL and QoS information is stored in TCAM
- TCAM is used to make Layer 2 forwarding decisions. CAM is used to build routing tables
Correct answer: C
Explanation:
When using Ternary Content Addressable Memory (TCAM) inside routers it’s used for faster address lookup that enables fast routing. In switches Content Addressable Memory (CAM) is used for building and lookup of mac address table that enables L2 forwarding decisions. Besides Longest-Prefix Matching, TCAM in today’s routers and multilayer Switch devices are used to store ACL, QoS and other things from upper-layer processing.

Question 3
Which two southbound interfaces originate from Cisco DNA Center and terminate at fabric underlay switches? (Choose two)
- UDP 67: DHCP
- ICMP: Discovery
- TCP 23: Telnet
- UDP 162: SNMP
- UDP 6007: NetFlow
Correct answer: BD
Explanation:
In the figure below, we can see ICMP & SNMP can reach to underlay switches. In the figure below, we can see ICMP & SNMP can reach to underlay switches.
