Question 1

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.

Question 2

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

AR1 is configured to participate in both Level 1 and Level 2.

BR2 is configured to participate in both Level 1 and Level 2.

CR1 is configured to participate in Level 2 only.

DR2 is configured to participate in Level 2 only.

Answer : A, D

Question 3

Which address range is used for source-specific multicast?

A239.0.0.0/8

B233.0.0.0/8

C232.0.0.0/8

D224.2.0.0/16

Answer : C

PIM SSM introduces new terms for many of the concepts in PIM sparse mode. PIM SSM can technically be used in the entire 224/4 multicast address range, although PIM SSM operation is guaranteed only in the 232/8 range (232.0.0/24 is reserved). The new SSM terms are appropriate for Internet video applications and are summarized in Table 1. https://www.juniper.net/documentation/us/en/software/junos/multicast/topics/concept/multicast-pim-ssm.html

Question 4

You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS.

Which well-known BGP community should be assigned to these addresses to accomplish this task?

Ano-export

Bno-peer

Cinternet

Dno-advertise

Answer : A

For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997:

no-advertise---Routes containing this community name are not advertised to other BGP peers.

no-export---Routes containing this community name are not advertised outside a BGP confederation boundary.

no-export-subconfed---Routes containing this community are advertised to IBGP peers with the same AS number, but not to members of other confederations.

llgr-stale---Adds a community to a long-lived stale route when it is readvertised.

no-llgr---Marks routes which a BGP speaker does not want to be retained by LLGR. The Notification message feature does not have any associated configuration parameters.

Question 5

You are deploying an 802.1X solution and must determine what would happen if clients are unable to re-authenticate to the RADIUS server.

In this scenario, which configuration would provide access to the network if the supplicant is already authenticated?

Amove

Bpermit

Cdeny

Dsustain

Answer : D

Question 6

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 7

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).
