Question 1 of 411
Which route summarization most efficiently reduces perceived network complexity that is composed of subnetworks ranging from 172.16.20.0/24 to
172.16.36.0/24?
Correct Answer: D

Question 2 of 411
What is the recommended subnet between two sites that have a point-to-point connection to conserve IP addresses?
Correct Answer: C

Question 3 of 411
In which OSI layer does IS-IS operate?
Correct Answer: C

IS-IS (Intermediate System to Intermediate System) is a routing protocol used to move information efficiently within a computer network and operates at OSI Layer 3, the Network Layer. It is primarily used in large service provider networks and is responsible for determining the best routing paths through a network.

Question 4 of 411
Which algorithm does IS-IS use to determine the shortest path through a network?
Correct Answer: C

IS-IS (Intermediate System to Intermediate System) uses Dijkstra's algorithm to determine the shortest path through a network. Dijkstra's algorithm is commonly used in link-state routing protocols, where each router maintains a complete map of the network and independently calculates the shortest path to each destination. This algorithm helps in efficiently determining the best path by considering various link states and their associated costs.

Question 5 of 411
Which unique EIGRP feature allows for faster Layer 3 convergence?
Correct Answer: B

Feasible successors are a unique feature of EIGRP that allows for faster Layer 3 convergence. When a route becomes unavailable, EIGRP can quickly switch to a feasible successor without the need to recalculate the entire routing table, significantly speeding up convergence time.
