What is the primary different between AAA authentication and authorization?

• A.Authentication verifies a username and password, and authorization handles the communication between the authentication agent and the user database.
• B.Authentication identifies a user who is attempting to access a system, and authorization validates the users password
• C.Authentication identifies and verifies a user who is attempting to access a system, and authorization controls the tasks the user can perform.
• D.Authentication controls the system processes a user can access and authorization logs the activities the user initiates

Which two actions influence the EIGRP route selection process? (Choose two)

• A.The router calculates the reported distance by multiplying the delay on the exiting Interface by 256.
• B.The router calculates the best backup path to the destination route and assigns it as the feasible successor.
• C.The router calculates the feasible distance of all paths to the destination route
• D.The advertised distance is calculated by a downstream neighbor to inform the local router of the bandwidth on the link
• E.The router must use the advertised distance as the metric for any given route

Correct Answer: B,C

The reported distance (or advertised distance) is the cost from the neighbor to the destination. It is calculated from the router advertising the route to the network. For example in the topology below, suppose router A & B are exchanging their routing tables for the first time. Router B says "Hey, the best metric (cost) from me to IOWA is 50 and the metric from you to IOWA is 90" and advertises it to router A.
Router A considers the first metric (50) as the Advertised distance. The second metric (90), which is from NEVADA to IOWA (through IDAHO), is called the Feasible distance.

The reported distance is calculated in the same way of calculating the metric. By default (K1 = 1, K2 = 0, K3 = 1, K4 = 0, K5 = 0), the metric is calculated as follows:
