Q36. You manage an IP fabric with an EVPN-VXLAN overlay. You have multiple tenants separated using multiple unique VRF instances. You want to determine the routing information that belongs in each routing instance’s routing table.
In this scenario, which property is used for this purpose?

the VRF target community

the routing instance type

the VRF table label

the route distinguisher value

Q37. You want to ensure that VXLAN traffic from the xe-0/0/12 interface is being encapsulated by logical vtep.32770 and sent to a remote leaf device.
In this scenario, which command would you use to verify that traffic is flowing?

monitor traffic interface xe-0/0/12

show interface terse vtep.32770

show interfaces terse vtep.32770 statistics

show interfaces vtep.32770 detail

Q38. Click the Exhibit button.

You are reviewing a configuration for an EVPN VLAN-bundle service. The configuration commits successfully, but the hosts connected to the MAC-VRF do not communicate correctly.
Referring to the exhibit, which two actions should you take to solve the problem? (Choose two.)

Use the delete routing-instances MAC-VRF-50 vlans v50 13-interface command.

Use the set routing-instances MAC-VRF-50 instance-type evpn-vpws command.

Use the delete routing-instances MAC-VRF-50 protocols evpn default-gateway command.

Use the set routing-instances MAC-VRF-50 service-type vlan-bundle command.

Q39. Which two statements are correct about an ERB architecture? (Choose two.)

The VTEPs in an ERB architecture terminate on the spine devices.

Routing in an ERB architecture occurs on the spine devices.

Routing in an ERB architecture occurs on the leaf devices.

The VTEPs in an ERB architecture terminate on the leaf devices.

Q40. You want to provide a OCI that keeps each data center routing domain isolated, while also supporting translation of VNIs. Which DCI scheme allows these features?

MPLS DCI label exchange

over the top (OTT) with VNI translation enabled

VXLAN stitching

over the top (OTT) with proxy gateways

Q41. You are asked for TX and RX traffic statistics for each interface to which an application server is attached. The statistics need to be reported every five seconds. Using the Junos default settings, which telemetry method would accomplish this request?

gNMI

SNMP

Native Sensors

OpenConfig

Q42. A local VTEP has two ECMP paths to a remote VTEP
Which two statements are correctwhen load balancing is enabled in this scenario? (Choose two.)

The inner packet fields are not used in the hash for load balancing.

The destination port in the UDP header is used to load balance VXLAN traffic.

The source port in the UDP header is used to load balance VXLAN traffic.

The inner packet fields are used in the hash for load balancing.

Q43. You are deploying an EVPN-VXLAN overlay. You must ensure that Layer 3 routing happens on the spine devices. In this scenario, which deployment architecture should you use?

ERB

CRB

bridged overlay

distributed symmetric routing

Q44. Exhibit.

A VXLAN tunnel has been created between leaf1 and Ieaf2 in your data center. Referring to the exhibit, which statement is correct?

Traffic sent from server1 to server2 will be dropped on Ieaf2.

Traffic sent from server1 to server2 will be tagged with VLAN ID 100 on Ieaf2 and forwarded to server2.

Traffic sent from server1 to server2 will be tagged with VLAN ID 200 on Ieaf2 and forwarded to server2.

Traffic sent from server1 to server2 will be dropped on leaf1.

Q45. Which two statements describe the function of the Designated Forwarder (DF) in an EVPN- VXLAN all-active multihoming scenario? (Choose two.)

It is elected per Ethernet Segment and VLAN.

It forwards all unicast known traffic for the segment.

It is responsible for forwarding BUM traffic to the multihomed segment.

It prevents duplicate BUM traffic from being sent to the multihomed CE device.

Q46. A customer wants any device-to-device link in the routed underlay infrastructure to fail over in less than two seconds. They do not want to adjust the routing protocol timers due to the size of the network. In this scenario, which feature should they use to satisfy the requirements?

BFD

LLDP

RSTP

MC-LAG

Q47. Given the configuration shown in the exhibit, why has the next hop remained the same for the EVPN routes advertised to the peer 203.0.113.2?

EVPN routes cannot have the next hop changed.

The export policy is incorrectly configured.

The vrf-export parameter must be applied.

The vpn-apply-export parameter must be applied to this peer.

Q48. Exhibit.

Connections between hosts connected to Leaf-1 and Leaf-2 are not working correctly.

Referring to the exhibit, which two configuration changes are required to solve the problem? (Choose two.)

Configure the setswitch-options vtep-source-interface irb.0parameter on Leaf-1.

Configure the set switch-options vrf-target target:65000:l parameteron Leaf-2.

Configure the setswitch-options route-distinguisher i92.168.100.50:i parameter on Leaf-1.

Configure the setswitch-options service-id 1 parameter on Leaf-2.

Q49. You are deploying an IP fabric using EBGP and notice that your leaf devices are advertising and receiving all the routes. However, the routes are not installed in the routing table and are marked as hidden.
Which two statements describe how to solve the issue? (Choose two.)

You need to configure as-override.

You need to configure a next-hop self policy.

You need to configure loops 2.

You need to configure multipath multiple-as.

Q50. Exhibit.

Given the configuration shown in the exhibit, why has the next hop remained the same for the EVPN routes advertised to the peer 203.0.113.2?

EVPN routes cannot have the next hop changed.

The export policy is incorrectly configured.

The vrf-export parameter must be applied.

The vpn-apply-export parameter must be applied to this peer.

Q51. Exhibit.

Referring to the exhibit, which statement is correct?

VNI 100 is not configured on the remote VTEP.

The MAC address is unknown and not in the forwarding table of the remote VTEP.

The remote VTEP is not responding.

The MAC address is known but not reachable by the remote VTEP

Q52. What are three actions available for MAC move limiting? (Choose three.)

drop

filter
