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

Question 1

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 2

Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.

How would you accomplish this task?

AConfigure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.

BConfigure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.

CConfigure interface ge-0/0/3 to a mode trunk to assign the VLANs.

DConfigure VSTP on interface ge-0/0/1 to assign the VLANs.

Answer : C

Question 3

You are asked to implement fault tolerant RPs in your multicast network.

Which two solutions would accomplish this behavior? (Choose two.)

AUse BFD with statically defined RPs.

BUse MSDP with statically defined RPs.

CUse anycast PIM with statically defined RPs.

DUse IGMPv3 with statically defined RPs.

Answer : B, C

Question 4

A Layer 2 connection does not expend across data centers. The IP subnet in a Layer 2 domain is confined within a single data center.

Which EVPN route type is used to communicate prefixes between the data centers?

AType 1

BType 2

CType 4

DType 5

Answer : D

Question 5

You must provide network connectivity to hosts that fail authentication.

In this scenario, what would be used in a network secured with 802.1X to satisfy this requirement?

AConfigure the native-vlan-id parameter on the port.

BUse the server-reject-vlan command to specify a guest VLAN.

CConfigure a secondary IP address on the port for unauthenticated hosts.

DConfigure the port as a spanning tree edge port.

Answer : B

For a device configured for 802.1X authentication, specify that when the device receives an Extensible Authentication Protocol Over LAN (EAPoL) Access-Reject message during the authentication process between the device and the RADIUS authentication server, supplicants attempting to access the LAN are granted access and moved to a specific bridge domain or VLAN. Any bridge domain, VLAN name or VLAN ID sent by a RADIUS server as part of the EAPoL Access-Reject message is ignored.

Question 6

Which three statements are correct about EVPN route types? (Choose three.)

AType 3 routes carry replication information.

BType 2 routes carry endpoint MAC address information.

CType 2 routes carry endpoint IP address information.

DType 5 routes carry replication information.

EType 1 routes carry endpoint MAC address information.

Answer : A, B, C

Cisco explains it better: The EVPN control plane advertises the following types of information:

Route type 1 -- This is an Ethernet Auto-Discovery (EAD) route type used to advertise Ethernet segment identifier, Ethernet Tag ID, and EVPN instance information. EAD route advertisements may be sent for each EVPN instance or for each Ethernet segment.

Route type 2 -- This advertises endpoint reachability information, including MAC and IP addresses of the endpoints or VTEPs.

Route type 3 -- This performs multicast router advertisement, announcing the capability and intention to use ingress replication for specific VNIs.

Route type 4 -- This is an Ethernet Segment route used to advertise the Ethernet segment identifier, IP address length, and the originating router's IP address.

Route type 5 -- This is an IP prefix route used to advertise internal IP subnet and externally learned routes to a VXLAN network.

Question 7

Which two multicast listener registration protocols are supported in the Junos operating system? (Choose two.)

AMLD

BDVMRP

CIGMP

DPIM

Answer : A, C

internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the Multicast Group Membership Discovery (MGMD) protocols
