- A: IP protocol number 89
- B: TCP port 179
- C: UDP port 179
- D: IP protocol number 6
Correct Answer: A
Which statement is true about default BGP route redistribution behavior?
- A: IBGP-learned routes are advertised only to other IBGP peers.
- B: EBGP-learned routes are redistributed into any IGPs.
- C: EBGP-learned routes are advertised only to other EBGP peers.
- D: EBGP-learned routes are advertised to other IBGP and EBGP peers.
Correct Answer: D
In a PIM-SM network, which type of node helps to build a tree towards an unknown multicast source?
- A: DIS
- B: RP
- C: DR
- D: BSR
Correct Answer: B
Which statement is true about MVRP?
- A: It allows you to split a broadcast domain into multiple isolated broadcast subdomains.
- B: It dynamically manages VLAN registration in a LAN.
- C: It maps multiple independent spanning-tree instances onto one physical topology.
- D: It is a Layer 2 protocol that facilitates network and neighbor discovery.
Correct Answer: B
Which statement is true about LLDP?
- A: It allows you to split a broadcast domain into multiple isolated broadcast subdomains.
- B: It dynamically manages VLAN registration in a LAN.
- C: It maintains a separate spanning-tree instance for each VLAN.
- D: It is a Layer 2 protocol that facilitates network and neighbor discovery.
Correct Answer: D

Which statement is true about the IPv6 network shown in the exhibit?
- A: OSPFv2 must be configured to route IPv4 prefixes.
- B: Areas 1 and 2 cannot be a stub or NSSA.
- C: OSPFv3 can use MD5 authentication.
- D: OSPFv3 can route IPv4 prefixes.
Correct Answer: D
-- Exhibit –
Referring to the exhibit, what is the shortest path from R6 to R5?
- A: R6, R4, R2, R1, R3, R5
- B: R6, R4, R2, R3, R5
- C: R6, R4, R5
- D: R6, R5
Correct Answer: D
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?
- A: R1's route is preferred because Type 1 metrics take into account the external cost only.
- B: R1's route is preferred because Type 1 metrics take into account the internal and external cost.
- C: R2's route is preferred because Type 2 metrics take into account the internal and external cost.
- D: R2's route is preferred because Type 2 metrics take into account the external cost only.
Correct Answer: D
-- Exhibit –
Referring to the exhibit, which LSA type will Router R2 inject into Area 1?
- A: Type 3 LSA
- B: Type 4 LSA
- C: Type 5 LSA
- D: Type 7 LSA
Correct Answer: A
