[JN0-662 Free Questions] JN0-662 Service Provider Routing and Switching, Professional (JNCIP-SP)

1. Which two types of LSAs have a domain scope? (Choose two.)

Type 7

Type 2

Type 10

Type 5

2. You are asked to configure a new Layer 3 VPN.

In this scenario, which routing-instance type must be used?

vpls

evpn

vrf

12vpn

3. Which authentication strategy authenticates IS-IS hello PDUs only?

interface authentication

area authentication

domain authentication

level authentication

4. Which transport mechanism is required for Layer 3 VPNs?

GRE

VXLAN

IPsec

MPLS

5. You are asked to configure PIM-SM in your network. Your implementation must allow for load sharing between redundant RPs and, should an RP failure occur, the RP failover time should be minimized.

Which two configuration tasks are required in this scenario? (Choose two.)

Configure MSDP peering sessions between the routers designated as RPs.

Configure the shared anycast address on the RPs as the primary address on the loopback interface.

On the routers designated as RPs, configure the shared anycast address on the loopback interface.

Configure at least two static RPs and bundle them in an RP redundancy group under [edit protocols pim].

6. In a carrier-of-carrier VPN model, which type of network layer reachability information is used for the MP-BGP signaling between CE and PE routers?

flow

labeled-unicast

unicast

inet-vpn

7. You want to add a new OSPF area to your existing OSPF network, however, this area will not be directly connected to Area 0. Which feature would you use to complete this task?

a routing policy

not-so stubby area

virtual link

Type 10 LSA

8. Which statement is correct regarding BGP route reflectors?

The route reflectors must have a private AS number.

The route reflectors must have an EBGP peering session between each other.

The route reflectors must have a cluster ID configured.

The route reflectors must have a different AS number than the clients.

9. You want to use IS-IS on a GRE interface where the underlying Layer 3 MTU is 1500.

Which statement is correct in this scenario?

IS-IS can be used because every IS-IS interface must be capable of transmitting packets at least as large as 1476 bytes, and the GRE header is 24 bytes.

IS IS can be used, but the networking device directly attached to the circuit must be capable of fragmentation.

IS-IS cannot be used, but the router can enable a GRE key that serves the same function as IS-IS.

IS-IS cannot be used because the IS-IS hello is not allowed to be fragmented and has the DF bit set.

10. You are asked to deploy VPLS in your network as a new service for several customers, and you must identity the configuration and provisioning requirements for your customers. Which two statements are correct in this scenario? (Choose two.)

CE interfaces facing the service prowler must be Ethernet interfaces.

VLAN IDs defined on CE interfaces must be the same on both ends unless otherwise negotiated.

CE interfaces facing the service provider must be Layer 3 interfaces.

PE interfaces facing the core must have VPLS encapsulation enabled.
