Demo Questions

Question 1
An engineer is implementing a Cisco MPLS TE tunnel to improve the streaming experience for the clients of a video-on-demand server. Which action must the engineer perform to configure extended discovery to support the MPLS LDP session between the headend and tailend routers?
  1. Configure the interface bandwidth to handle TCP and UDP traffic between the LDP peers
  2. Configure a Cisco MPLS TE tunnel on both ends of the session
  3. Configure an access list on the interface to permit TCP and UDP traffic
  4. Configure a targeted neighbor session.
Correct answer: B
Question 2
What is a characteristic of a next-generation firewall?
  1. only required at the network perimeter
  2. required in each layer of the network
  3. filters traffic using Layer 3 and Layer 4 information only
  4. provides intrusion prevention   
Correct answer: D
Explanation:
The feature set for NGFWs build upon traditional firewall features by including critical security functions like intrusion prevention, VPN, and anti-virus, and even encrypted web traffic inspection to help prevent packets containing malicious content from entering the network

Question 3
What is the difference between a RIB and a FIB?
  1. The RIB is used to make IP source prefix-based switching decisions
  2. The FIB is where all IP routing information is stored
  3. The RIB maintains a mirror image of the FIB
  4. The FIB is populated based on RIB content 
Correct answer: D
Explanation:
CEF uses a Forwarding Information Base (FIB) to make IP destination prefix-based switching decisions. The FIB is conceptually similar to a routing table or information base. It maintains a mirror image of the forwarding information contained in the IP routing table. When routing or topology changes occur in the network, the IP routing table is updated, and those changes are reflected in the FIB. The FIB maintains next-hop address information based on the information in the IP routing table. Because there is a one-to-one correlation between FIB entries and routing table entries, the FIB contains all known routes and eliminates the need for route cache maintenance that is associated with earlier switching paths such as fast switching and optimum switching. Note: In order to view the Routing information base (RIB) table, use the “show ip route” command. To view the Forwarding Information Base (FIB), use the “show ip cef” command. RIB is in Control plane while FIB is in Data plane.
