In an EVPN multicast environment, which two route types facilitate IGMP join and IGMP leave behavior for multihomed sites? (Choose two.)
After configuring an IP fabric using EBGP as you protocol, you notice that not all of the routers are showing up in the routing tables. You have verified that all adjacencies have formed, and place and configured properly.
In this scenario, which statement is true?
Referring to the exhibit, what would cause the problem on VCP 0/50?

Which two statements describe EVPN based VXLAN implementations? (Choose two.)
Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor
using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load- share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B.
Which two actions must be performed to accomplish this task? (Choose two.)
You are required to create an IP fabric for your new data center. In this scenario, which protocol would be used to support EVPN?
Referring to the exhibit,
what happens when you initiate ZTP on a QFX5120 switch running Junos
21.3R1.9?
You are troubleshooting a problem with traffic not reaching a remote VTEP. Referring to the
exhibit, what is the reason for the problem?
Referring to the exhibit, which two statements are correct?(Choose two.)
Your colleague has begun working on the base configuration for an active-active multihomed
EVPN connection shown in the exhibit.
Which two actions will ensure a successful implementation? (Choose two.)
Which statement is correct about the highlighted code segment and VXLAN frame shown in the exhibit?
You are building a new IP fabric data center underlay network and want to ensure predicted load- balancing behavior for traffic, traversing the fabric. What are two approaches you should take to satisfy the requirement in this scenario? (Choose two.)
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?
You have a data center design with multiple tenants using routing instances.
In this scenario, what are two ways to provide inter-tenant communications? (Choose two.)
Which statement is true about a Data center interconnect over an IP network?

In this scenario, which two juniper best practices would accomplish this task? (Choose two.)
You host a multitenant data center that runs VMware. You must perform deep packet inspection
on all inter-tenant traffic that is flowing between the VMs within the same hypervisor. Your solution must provide the security services without needing to leave the physical device. In this scenario, what should you do to solve this problem?
A VTEP requires which two interfaces? (Choose two.)
Referring to the exhibit, which statement is correct?
You are troubleshooting a connectivity issue across a VXLAN overlay network. In the exhibit, you are using the ping overlay command from a local VTEP residing on a OFX 5120 to a remote VTEP residing on a separate QFX5120.
What is the problem in this situation?
You are deploying a data center switch using ZTP. You want the switch to be upgraded to a specific software image and you want a specific configuration file applied when the switch boots with its factory default configuration.
