B. route dampening of current customers

C. BGP suboptimal routing

D. routers and switches hardware capabilities

E. IPv4 exhaustion

F. multihoming policies of new customers

G. BGP blackholing when acting as transit autonomous system

Correct Answer: C,D,G

Question 2

A network engineer implements IS-IS authentication in a router. When the engineer implements the same password on the router's peer, the output below is displayed with the debug IS-IS authentication information:

Question 10

An engineer wants to define a route policy that sets MED to a given value in case the extended community attributes of a network prefix match at least one of the values:
65000:10, 65000:20, or 65000:30. Which configuration accomplishes this task?

A. extcommunity-set rt my-list
65000:10
65000:20
65000:30
end-set
route-policy my-list ($med)
if extcommunity rt matches-any my-list then
set met $med

B. extcommunity-set rt my-list
65000:10
65000:20
65000:30
end-set
route-policy my-list ($med)
if extcommunity rt matches-within my-list then
set met $med

C. extcommunity-set rt my-list
65000:10
65000:20
65000:30
end-set
route-policy my-list ($med)
if extcommunity rt matches-within my-list or med is $med is then
set met $med

D. extcommunity-set rt my-list
65000:10
65000:20
65000:30
end-set
route-policy my-list ($med)
if extcommunity rt matches-any my-list or med is $med then
pass
