Which of the following distance vector features prevents routing loops by causing the routing protocol to advertise only a subset of known routes, as opposed to the full routing table, under normal stable conditions?
Answer
Route poisoning
Poison reverse
DUAL
Split horizon
Question 2
Question
Which of the following distance vector features prevents routing loops by advertising an infinite metric route when a route fails?
Answer
Dijkstra SPF
DUAL
Split horizon
Route poisoning
Question 3
Question
Routers A and B use EIGRP. How does router A watch for the status of router B so that router A can react if router B fails?
Answer
By using EIGRP Hello messages, with A needing to receive periodic Hello messages to believe B is still working
By using EIGRP update messages, with A needing to receive periodic update messages to believe B is still working
Using a periodic ping of B’s IP address based on the EIGRP neighbor timer
None listed
Question 4
Question
Which of the following affect the calculation of EIGRP metrics when all possible default values are used? (Choose two answers.)
Answer
bandwidth
delay
load
reliability
MTU
hop count
Question 5
Question
Which of the following is true about the concept of EIGRP feasible distance?
Answer
A route’s feasible distance is the calculated metric of a feasible successor route
A route’s feasible distance is the calculated metric of the successor route
The feasible distance is the metric of a route from a neighboring router’s perspective.
The feasible distance is the EIGRP metric associated with each possible route to reach a subnet.
Question 6
Question
Which of the following is true about the concept of EIGRP reported distance?
Answer
A route’s reported distance is the calculated metric of a feasible successor route.
A route’s reported distance is the calculated metric of the successor route.
A route’s reported distance is the metric of a route from a neighboring router’s perspective.
The reported distance is the EIGRP metric associated with each possible route to reach a subnet.
