e. Integrated IS-IS
2. Which of the following routing protocols use a metric that is, by default, at least partially
affected by link bandwidth? (Choose two answers.)
a. RIP-1
b. RIP-2
c. EIGRP
d. OSPF
3. Which of the following interior routing protocols support VLSM? (Choose four answers.)

4. Which of the following is true about how a router using a link-state routing protocol
chooses the best route to reach a subnet?
a. The router finds the best route in the link-state database.
b. The router calculates the best route by running the SPF algorithm against the information
in the link-state database.
c. The router compares the metrics listed for that subnet in the updates received from
each neighbor and picks the best (lowest) metric route.
d. The router uses the path that has the lowest hop count.

terms refer to that algorithm? (Choose two answers.)
a. SPF
b. DUAL
c. Feasible successor
d. Dijkstra
e. Good old common sense
