1. Your organization has recently acquired another company. You must carry all of the company’s existing VLANs across the corporate backbone to the existing branch locations without changing addressing and with minimal configuration.

Which technology will accomplish this task?

Q-in-Q all-in-one bundling

PVLAN isolated VLAN

MVRP registration normal

EVPN-VXLAN anycast gateway

2. There are two BGP routes to 10.200.200.0/24 received from two external peers. Route 1 comes from a neighbor with a router ID of 10.10.100.1 and a peer IP address of 10.10.30.1, and route 2 comes from a neighbor with a router ID of 10.10.200.1 and a peer IP address of 10.10.50.1. Both routes have the same MED value, origin value, AS path length, and local preference number.

In this scenario, which statement is correct about the active route?

Route 1 will be active because of the peer IP address.

Route 2 will be active because of the peer IP address.

Route 1 will be active because of the router I

Route 2 will be active because of the router I

3. You are deploying new Juniper EX Series switches in a network that currently is using Cisco’s Per-VLAN spanning tree plus (PVST+) and you must provide compatibility with this environment.

Which spanning tree protocol do you deploy in this scenario?

STP

MSTP

VSTP

RSTP

4. The connection between DC1 and DC2 is routed as shown in the exhibit.

In this scenario, which statement is correct?

The border devices must be able to perform Layer 3 routing and provide IRB functionality.

L3VPN must be enabled to advertise reachability.

An IP prefix route provides encoding for intra-subnet forwarding.

Type 2 and Type 5 routes will be exchanged between DC1 and DC2.

5. Referring to the exhibit, which LSA type is used to advertise 192.168.1.0/24 to R5?

Type 5

Type 4

Type 3

Type 7

6. Referring to the exhibit, which two statements are correct? (Choose two.)

BPDUs from the root bridge for VLAN 10 have been received on the ge-0/0/7.0 interface.

DS-1 is the root bridge for VLAN 10.

BPDUs from the root bridge for VLAN 20 have been received on the ge-0/0/7.0 interface.

Default VSTP bridge priority values are configured.

7. BGP multipath or multihop are not configured in your network.

In this scenario, what is the correct sequence for BGP active route selection?

higher local preference shortest AS path lowest peer address lowest router ID lower origin code

higher local preference shortest AS path lower origin code lowest router ID lowest peer address

higher local preference lowest router ID lowest peer address lower origin code shortest AS path

higher local preference shortest AS path lowest router ID lowest peer address lower origin code

8. Your enterprise network uses routing instances to support multitenancy. Your Junos devices use BGP to peer to multiple BGP devices. You must ensure that load balancing is achieved within the routing instance.

Which two statements would accomplish this task? (Choose two.)

Configure the multipath option at the [edit protocols bgp group <group-name> neighbor] hierarchy.

Configure the multipath option at the [edit protocols bgp group] hierarchy.

Configure a load-balance per-packet policy and apply it at the [edit routing-options forwarding-table] hierarchy.

Configure the multipath option at the [edit routing-instances <instance-name> routing-options] hierarchy.

9. When using wide metrics, which two statements about route advertisement between IS-IS levels are correct? (Choose two.)

Level 1 and Level 2 routers do not advertise Level 2 routes into the Level 1 area by default.

Level 1 routes are advertised to Level 2 routers by default.

If wide-metrics-only is configured, Level 1 routes are not advertised to Level 2 routers by default.

Level 1 routes advertised as external routes into Level 1 are not advertised to any Level 2 routers by default.

10. Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.

Which action would solve this problem?

Configure the links between the access switches and the distribution switch as a trunk port.

Disable the BPDU block function on the access switches.

Disable the BPDU block function on the distribution switch.

Configure a GRE tunnel to encapsulate the L2PT traffic across the WA

11. Which two statements are correct regarding the behavior shown in the exhibit? (Choose two.)

The ge-1/1/0 interface is configured as secondary for Area 0.

The router is an AB

The router is not an AB

The ge-1/1/0 interface is configured as secondary for Area 100.

12. Referring to the exhibit, a PIM-SM network is set up to enable communication between multicast devices.

Which two statements are true? (Choose two.)

Before the formation of the rendezvous-point tree, a join message is sent from R1 to R3.

Before the formation of the rendezvous-point tree, an IGMP is sent from the Receiver to R1.

Before the formation of the rendezvous-point tree, an IGMP is sent from the Source to R5.

Before the formation of the rendezvous-point tree, a join message is sent from R1 to R5.

13. Referring to the outputs shown in the exhibit, which two statements are correct about the IS-IS adjacency? (Choose two.)

R1 is configured to participate in both Level 1 and Level 2.

R2 is configured to participate in both Level 1 and Level 2.

R1 is configured to participate in Level 2 only.

R2 is configured to participate in Level 2 only.

14. Referring to the exhibit, which two statements are correct? (Choose two.)

The DS-2 switch will be root bridge for MSTI 2.

The DS-1 switch will be root bridge for MSTI 1.

The DS-1 switch will be root bridge for MSTI 2.

The DS-2 switch will be root bridge for MSTI 1.

15. What are two similarities between OSPFv2 and OSPFv3? (Choose two.)

virtual links

support for multiple instances per link

32-bit router ID

protocol processing per link, not per subnet

16. You are deploying IP phones in your enterprise network that must receive their power through their Ethernet connection. You are using your EX Series switch's PoE ports that support IEEE 802.3af.
