NO.23 You want to enable an EBGP-based IP fabric to allow ECMP routes to be populated into the RIB. In this scenario, which action will accomplish this task?

Enable the forwarding-options ecmp-do-local-lookup parameter.

Enable the multipath multiple-as BGP parameter.

Enable the routing-options multipath global parameter.

Enable the chassis ecmp-alb parameter.

NO.24 What happens when a packet is encapsulated by a VXLAN before being placed in the overlay?

The TTL is decremented by two and placed in the VXLAN header.

The QoS marketing are placed in the VXLAN header.

The VLAN-ID is placed in the VXLAN header.

A VNI that maps to the VLAN-ID placed in the VXLAN header.

When a packet is encapsulated by VXLAN, a VXLAN Network Identifier (VNI) is placed in the VXLAN header. This VNI is crucial as it maps to the VLAN-ID, ensuring that the packet is correctly identified and routed within the overlay network.

NO.25 Exhibit.

Which statement is true about the route shown in the exhibit?

The route target on this route is 1000

The route is an EVPN type-1 route.

The route uses a type-1 route distinguisher.

The VNI for this route is 304.

NO.26 You are configuring an EVPN overlay network. You want to ensure that leaf devices can respond to ARP
requests from locally connected hosts, when the leaf device knows the MAC of the intended destination.
In this scenario, what should you configure on the leaf devices to accomplish this task?

Proxy ARP

Static ARP entries

Persistent MAC learning

IGMP snooping

NO.27 Exhibit.

Referring to the exhibit, which statement is correct?

Leaf1 has not learned any MAC addresses

Leaf3 is the remote tunnel endpoint.

One tunnel is servicing multiple VLANs

Spanning Tree Protocol is disabled

NO.28 Exhibit.

Referring to the exhibit, which statement is correct?

The exhibit shows a 5-stage IP fabric architecture.

The exhibit shows a collapsed fabric architecture.

The exhibit does not represent a valid fabric architecture.

The exhibit shows a 3-stage IP fabric architecture.

NO.29 You work in a data center where VMs and hosts are frequently moved. Your design needs to eliminate
inefficient traffic flows.
In this scenario, which two solutions will satisfy this requirement? (Choose two.)

VXLAN

EVPN

VMTO

VPLS

Explanation
https://www.juniper.net/documentation/en_US/junos/topics/concept/evpn-ingress-vmto.html

NO.30 Exhibit.

Referring to the exhibit, you have a data center in which only the spine devices are using EVPN and VXLAN.
The leaf nodes are multihomed in active-active mode to the spine nodes through ESI LAG interfaces. In this design, a link failure on the interface connecting the spine nodes would also cause all traffic from the spine to the leaf nodes to drop.
In this scenario, which command configured on which nodes would solve this problem?

the disable protocols evpn no-core-isolation command on the spine nodes

the set protocols evpn no-core-isolation command on the spine nodes

the disable protocols evpn no-core-isolation command on the leaf nodes

the set protocols evpn no-core-isolation command on the leaf nodes

NO.31 You are asked to deploy an Ethernet bridging design in a data center with the following criteria:
– routing must occur on the leaf devices.
– VTEPs must terminate on the leaf devices.
– facilitate inter-VLAN communication.
– lower latency with East-West traffic.
Which architecture should you use in this scenario?

collapsed spine architecture

edge-routed bridging architecture

bridge overlay architecture

centrally-routed bridging architecture

Edge-routed bridging architecture fits all the criteria: routing occurs on leaf devices, VTEPs terminate on the leaf devices, facilitates inter-VLAN communication, and provides lower latency for East-West traffic due to its distributed nature.

NO.32 You are implementing an EVPN overlay in your IP fabric data center. The IP fabric was stable before configuring the overlay group and EVPN-related settings. After committing the configuration shown in the exhibit on your spine device, you are no longer exchanging any routes in your underlay fabric.

In this scenario, what will solve this problem?

You must move the EVPN NLRI family declaration to be applied under the overlay BGP group.

You must remove the export policy applied to your fabric group.

You must remove the multipath parameter from the overlay group.

You must change the overlay group to establish an EBGP peering instead of IBGP.

NO.33 You are deploying an EBGP IP fabric. In this scenario, which statement is true?

Each spine should peer with every other spine using physical addresses.

Each spine should peer with each leaf using loopback addresses.

Each spine should peer with every other spine using loopback addresses.

Each spine should peer with each leaf using physical addresses.

NO.34 You are attempting to configure filter-based forwarding in your data center. All traffic from Host1 that is going to Host2 should be inspected by the data center firewall. You have verified that the traffic is being forwarded from router leaf L1’s VRF-1 to its INSPECT-VRF. However, the traffic is not reaching service L2.
Referring to the exhibit, which two steps should you take to troubleshoot the problem? (choose two.)

Examine the INSPECT-VRF.evpn 0 route table on L1 for a default route that will direct the traffic to L2.

Examine the INSPECT-VRF.inet. 0 route table on L1 for a default route that will direct the traffic to L2.

Ensure that VRF-1 and INSPECT-VRF route targets on L1 and L2 match.

Ensure that the route target in the INSPECT-VRF of L1 matches the route target of the INSPECT-VRF of L2.

NO.35 Which two statements are correct about VXLAN domains? (Choose two.)

With Layer 2 traffic, the VLAN ID is discarded before the packet is sent.

With Layer 3 traffic, the VLAN ID is discarded before the packet is sent.

With Layer 2 traffic, the VLAN ID is transmitted within the packet.

With Layer 3 traffic, the VLAN ID is transmitted within the packet.

In VXLAN domains, when dealing with Layer 2 traffic, the original VLAN ID of the packet can be either transmitted within the VXLAN packet or discarded, depending on the specific implementation and configuration. When the VLAN ID is preserved, it allows for VLAN transparency, enabling the VXLAN to transport VLAN-tagged frames across the network. On the other hand, discarding the VLAN ID can simplify the encapsulation process but removes the original VLAN information from the packet. Reference: Juniper Networks VXLAN Implementation Guide.

NO.36 You are asked to deploy an Ethernet bridging design in a data center with the following criteria:
–routing must occur on the leaf devices.
–VTEPs must terminate on the leaf devices.
–facilitate inter-VLAN communication, — lower latency with East-West traffic.
Which architecture should you use in this scenario?

collapsed spine architecture

edge-routed bridging architecture

bridge overlay architecture

centrally-routed bridging architecture

NO.37 Which two statements define the use of route targets and route distinguishers in an EVPN? (Choose two.)

Route distinguishers ensure that routes from different client remain unique within the data center
domain

Route targets ensure that routes from different clients remain unique within the data center domain

Route distinguishers identify the VRF into which the route should be placed

Route targets identify the VRF into which the route should be placed

NO.38 Your manager asks you to secure ARP and DHCP traffic across your local Ethernet links In this scenario, which technology will accomplish this task?

SSL

MAC sec

IPsec

A firewall filter
