Juniper JN0-650 JNCIP-ENT Exam Questions Instant Access

Question 1

You have two multicast receivers connected to the same VLAN. You notice that the switch that they are connected to is forwarding multicast traffic out of all the ports in the same VLAN, instead of just the two ports for the connected multicast receivers

In this scenario, what would you configure to optimize multicast forwarding?

Apromiscuous mode

Bspanning tree

CIGMP snooping

DIRB interface

Answer : C

Question 2

You run a multivendor switching environment where you have configured VSTP. You have 450 VLANs and notice that some of your VLANs do not function properly. How should you change the configuration to get all 450 VLANs working?

AInclude the force-version stp; statement in your configuration

BEnable RSTP to handle additional VLANs.

CSet the VLAN max-age to 3600 or more.

DIncrease the bridge priority on all VLANs to at least 16k.

Answer : B

Question 3

Exhibit.

You have determined that traffic in your network is being routed through your route reflector instead of using the optimal path. Referring to the exhibit, what are two configuration changes on the route reflector that would solve the problem? (Choose two.)

Aset policy-options policy-statement NHS term 10 from route-type external

Bset protocols bgp group int-group import NHS

Cdelete protocols bgp group int-group export IfJHS

Dset policy-options policy-statement NHS term 10 from route-type internal

Answer : A, C

Question 4

You have created a private community VLAN called RND The private community VLAN works fine within switch S1, but traffic in the private RND community VLAN does not reach VLAN members connected to switch S2.

Which statement is correct in this scenario?

AThe RND Community VLAN needs to have the same 802.1Q tag as its parent VLAN

BThe RND community VLAN needs to have an associated 802.1Q tag associated with it.

CThe RND Community VLAN needs to be stripped of all 802.1Q tags.

DThe RND community VLAN needs to be defined as an isolated VLAN.

Answer : B

Question 5

Exhibit

Referring to the exhibit, what will enable active routes from both peers?

AConfigure neighbor 172.16.1.1 multipath under the ext-peers hierarchy.

BConfigure multipath under the ext-peers hierarchy

CConfigure neighbor 172.16.1.1 under the ext-peers hierarchy.

DConfigure neighbor 10.10.20.2 multipath under the ext-peers hierarchy.

Answer : A

Question 6

You are deploying IP phones in your enterprise networks. When plugged in. the IP phones must automatically be provided with their geographic location details by the EX Series switches.

In this scenario, which protocol should be used to enable this behavior?

ACDP

BLLDP-MED

CLLDP

DMP-BGP

Answer : B

Question 7

You are troubleshooting a multicast deployment in a network. Some multicast groups operate in PIM-ASM mode and others operate in PIM-SSM mode. While troubleshooting, you note the following:

- The network uses IGMPv2 for some segments and IGMPv3 for others.

- For group 232.1.1.1, receivers know the exact source IP of the multicast sender

- For group 239.10.10.10. receivers do not know the source address in advance.

Which two statements correctly describe the operational differences between these two modes in Junos OS? (Choose two.)

APIM-ASM supports multiple active sources for a group without requiring receivers to know them in advance, whereas PIM-SSM requires explicit source knowledge

BIn PIM-ASM. the DR first sends a PIM register message to the RP before switching to the shortest-path tree.

CPIM-SSM requires an RP for initial joins, whereas PIM-ASM can operate without one.

DPIM-SSM relies on IGMPv3 to signal both the source and the group in the join message, bypassing the RP entirely.
