Question 2
Which statement is true about default BGP route redistribution behavior?
- IBGP-learned routes are advertised only to other IBGP peers.
- EBGP-learned routes are redistributed into any IGPs.
- EBGP-learned routes are advertised only to other EBGP peers.
- EBGP-learned routes are advertised to other IBGP and EBGP peers.
Correct answer: D
Question 3
In a PIM-SM network, which type of node helps to build a tree towards an unknown multicast source?
- DIS
- RP
- DR
- BSR
Correct answer: B
Question 4
Which statement is true about MVRP?
- It allows you to split a broadcast domain into multiple isolated broadcast subdomains.
- It dynamically manages VLAN registration in a LAN.
- It maps multiple independent spanning-tree instances onto one physical topology.
- It is a Layer 2 protocol that facilitates network and neighbor discovery.
Correct answer: B

Question 5
Which statement is true about LLDP?
- It allows you to split a broadcast domain into multiple isolated broadcast subdomains.
- It dynamically manages VLAN registration in a LAN.
- It maintains a separate spanning-tree instance for each VLAN.
- It is a Layer 2 protocol that facilitates network and neighbor discovery.
Correct answer: D
Question 6
Which CoS feature avoids congestion in a device by limiting traffic on ingress interfaces?
- rewrite rule
- scheduler
- drop profile
- policer
Correct answer: A
Question 7
-- Exhibit –
Which statement is true about the IPv6 network shown in the exhibit?
- OSPFv2 must be configured to route IPv4 prefixes.
- Areas 1 and 2 cannot be a stub or NSSA.
- OSPFv3 can use MD5 authentication.
- OSPFv3 can route IPv4 prefixes.
Correct answer: D
Question 8
-- Exhibit –
Referring to the exhibit, what is the shortest path from R6 to R5?
- R6, R4, R2, R1, R3, R5
- R6, R4, R2, R3, R5
- R6, R4, R5
- R6, R5
Correct answer: D
Question 9
R1 and R2 are ASBRs in the same area, each with an equal cost external path to the same external network prefix. R1 advertises an external route into OSPF with a Type 1 metric. R2 advertises an external route into OSPF with a Type 2 metric.
Which route would be preferred?
- R1's route is preferred because Type 1 metrics take into account the external cost only.
- R1's route is preferred because Type 1 metrics take into account the internal and external cost.
- R2's route is preferred because Type 2 metrics take into account the internal and external cost.
- R2's route is preferred because Type 2 metrics take into account the external cost only.
Correct answer: D
Question 10
-- Exhibit –
Referring to the exhibit, which LSA type will Router R2 inject into Area 1?
- Type 3 LSA
- Type 4 LSA
- Type 5 LSA
- Type 7 LSA
Correct answer: A
