JNCIS-DC Practice Questions - Juniper JNCIS-DC Specialist Data Center Exam - JNCIS-DC Practice Questions - Juniper JNCIS-DC Specialist Data Center Exam

Question 1

In a VXLAN-EVPN fabric, a VTEP advertises a Type 2 MAC/IP route primarily to achieve which outcome?

Distribute remote MAC and IP bindings so other VTEPs can perform ARP suppression locally Announce the availability of a new VTEP loopback for underlay ECMP Signal the establishment of a new VXLAN tunnel with a static VNI assignment Flush all remote MAC addresses associated with an Ethernet Segment during failover

Correct Answer:

Distribute remote MAC and IP bindings so other VTEPs can perform ARP suppression locally

Question 2

An EVPN Type 3 Inclusive Multicast Ethernet Tag (IMET) route is generated by a VTEP when:

The VTEP needs to join a BUM replication tree and advertise its ability to receive broadcast, unknown unicast, and multicast traffic for a given EVI A remote host's MAC address is learned dynamically through data-plane flooding An inter-DC EVPN gateway requires prefix routing to leak Type 5 routes between VRFs An ESI link failure triggers an immediate mass withdrawal of all MAC routes for that segment

Correct Answer:

The VTEP needs to join a BUM replication tree and advertise its ability to receive broadcast, unknown unicast, and multicast traffic for a given EVI

Question 3

Which EVPN route type carries an IP prefix (rather than a MAC address) and is used to leak Layer 3 routes between VRFs in a VXLAN fabric?

Type 5 IP Prefix Route Type 2 MAC/IP Advertisement Route Type 4 Ethernet Segment Route Type 3 Inclusive Multicast Ethernet Tag Route

Correct Answer:

Type 5 IP Prefix Route

Question 4

In EVPN multi-homing, the Type 1 Ethernet Auto-Discovery (A-D) route per-ESI is primarily used to:

Enable mass withdrawal of all MAC/IP routes for an Ethernet Segment when the uplink to that segment fails Advertise a host IP address to a remote VTEP for ARP suppression Announce VTEP reachability for BUM traffic replication across all VNIs Carry an IP prefix from a tenant VRF to a WAN gateway

Correct Answer:

Enable mass withdrawal of all MAC/IP routes for an Ethernet Segment when the uplink to that segment fails

Question 5

An Ethernet Segment Identifier (ESI) in EVPN multi-homing is configured on:

The interface(s) connecting the leaf switches to the multi-homed CE device, using the same ESI value on all participating leaf switches The BGP peer group between spine and leaf, to identify the underlay link bundle Each VXLAN tunnel interface on the leaf to uniquely identify the VNI-to-VRF mapping The loopback interface of each leaf to distinguish its VTEP from others in the same EVPN instance

Correct Answer:

The interface(s) connecting the leaf switches to the multi-homed CE device, using the same ESI value on all participating leaf switches
