Juniper JN0-649 JNCIP-ENT Exam Practice Test Instant Access

Question 1

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

AThe BGP neighbor can advertise L3 VPN related routes.

BThe BGP neighbor cannot advertise EVPN related routes.

CThe BGP neighbor can advertise EVPN related routes.

DThe BGP neighbor cannot advertise L3 VPN related routes.

Answer : A, C

Question 2

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

AThe maximum wattage that this switch can allocate to attached Ethernet devices is 100 watts.

BIf the total power consumption exceeds 90 watts, the ge-0/0/11 interface will continue to receive power.

CPoE is not enabled on the ge-0/0/0 interface.

DThe ge-0/0/10 interface supports PoE+.

Answer : A, D

POE is enabled in the interface ge-0/0/0 but nothing is connected to it. switch is in AT mode (poe+) and interface ge-0/0/11 supports poe+ judging by maximun wattage

Question 3

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

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

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

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

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

Answer : C, D

Bridge priority is to determine which bridge becomes the designated bridge.

Question 4

A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network.

Which two statements are correct in this scenario? (Choose two.)

ABoth the next hops will be used to forward traffic to R2.

BA routing policy will be required to forward traffic to both next hops.

CThe TTL value of 1 is set to limit the scope of the EBGP session.

DThe ttl statement must be configured to accommodate peering to a loopback address of a directly connected peer.

Answer : B, D

Question 5

Referring to the exhibit, ServerA sends a single IP packet destined to 10.0.0.127.

Which two statements correctly describe the behavior of the resulting outbound VXLAN packets that contain the original packet destined to 10.0.0.127? (Choose two.)

ARouter E will replicate and send a copy of the received VXLAN packet to router D.

BRouter C will send a VXLAN packet destined only to router D and router E.

CRouter D will not replicate and send a copy of the received VXLAN packet to router E.

DRouter C will send a single VXLAN packet to one remote VTEP.

Answer : A, D

Question 6

You enable the Multiple VLAN Registration Protocol (MVRP) to automate the creation and management of virtual LANs.

Which statement is correct in this scenario?

AThe forbidden mode does not register or declare VLANs.

BWhen enabled, MVRP affects all interfaces.

CTimers dictate when link state changes are propagated.

DMVRP works with RSTP and VSTP.

Answer : A

The forbidden mode does not register or declare VLANs. You can change the registration mode of a specific interface to forbidden. An interface in forbidden registration mode does not participate in MVRP even if MVRP is enabled on the switch.

https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/mvrp.html

MVRP is disabled by default on the switches and, when enabled, affects only trunk interfaces. Once you enable MVRP, all VLAN interfaces on the switch belong to MVRP (the default normal registration mode) and those interfaces accept PDU messages and send their own PDU messages. forbidden---The interface does not register or declare VLANS (except statically configured VLANs).

Question 7

Your enterprise network is running BGP VPNs to support multitenancy. Some of the devices with which you peer BGP do not support the VPN NLRI. You must ensure that you do not send BGP VPN routes to the remote peer.

Which two configuration steps will satisfy this requirement? (Choose two.)

AConfigure an import policy on the remote peer to reject the routes when they are received.

BConfigure an export policy on the local BGP peer to reject the VPN routes being sent to the remote peer.

CConfigure a route reflector for the VPN NLRI.

DConfigure the apply-vpn-export feature on the local BGP peer.

Answer : B, D

Apply both the VRF export and BGP group or neighbor export policies (VRF first, then BGP) before routes from the vrf or l2vpn routing tables are advertised to other PE routers.
