Question 1 of 1066
What is the difference between a RIB and a FIB?
Answer

Suggested Answer

The suggested answer is A.

The difference between a RIB and a FIB lies in their functions and the type of information they handle. The Routing Information Base (RIB) is essentially the routing table where all routing information, including multiple possible routes and routing metrics, is stored. On the other hand, the Forwarding Information Base (FIB) is a more streamlined structure used by the router to make actual packet forwarding decisions. The FIB is populated based on the information contained in the RIB, selecting the best routes decided by the routing algorithms. Thus, the FIB is derived from the RIB, and this forms the core distinction between the two.

Question 2 of 1066
Which QoS component alters a packet to change the way that traffic is treated in the network?
Answer

Suggested Answer

The suggested answer is C.

Marking is the QoS component that alters bits in the packet header to indicate its priority level or other attributes. This alteration allows network devices to treat the packet according to its assigned priority, thereby changing the way the traffic is handled within the network. Policing, classification, and shaping, while important QoS components, do not directly alter the packet itself to achieve this. Policing controls the rate of traffic, classification identifies traffic types, and shaping smooths traffic flows, but none of these directly modify the packet to influence its treatment like marking does.

Question 4 of 1066
Which statement about Cisco Express Forwarding is true?
Answer

Suggested Answer

The suggested answer is C.

Cisco Express Forwarding (CEF) maintains two tables in the data plane: the Forwarding Information Base (FIB) and the adjacency table. The FIB is used to make IP destination prefix-based switching decisions, while the adjacency table maintains the layer 2 next-hop information necessary for packet forwarding. This design allows CEF to improve the efficiency and speed of packet forwarding by pre-computing the necessary information and storing it in these tables.

Question 5 of 1066
What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment?
Answer

Suggested Answer

The suggested answer is D.

A benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment is lower latency between systems that are physically located near each other. This is because data does not need to travel over the internet, reducing delays and improving communication speed between systems.
