What are two reasons why MPLS would be used a transport for this DCI solution? (Choose two.)

Question15:
You are attempting to deploy a VCF as shown in the exhibit. SW-1 and SW-2 are functioning as the spine devices and SW-3 and SW-4 are functioning as the leaf devices. However, the VCF is not functioning properly.
Which two actions would solve this problem? (Choose two.)

Question16:
Spine 1 and Spine 2 are MX Series devices configured to act as redundant VXLAN Layer 3 Gateways using the virtual-gateway-address 10.0.1.254statement, Referring to the exhibit, how will a spine node react to receiving the ARP request from Host A?

Question17:
Referring to the exhibit, R1 and R2 are QFX5100s and are acting as VXLAN Layer 2 Gateways for VLAN
100 using PIM-SM signaling. R2 currently has only the (*.G) state established for VNI 5100.
Which event will cause R2 to establish the (S,G) state for VNI 5100 using R1 as the multicast source?

Question18:
You are deploying a VXLAN using EVPN signaling overlay network. PE1 and PE2 are multihomed to the connected CE device. You notice that the traffic is not load-balancing as expected.
Referring to the exhibit, which two actions will solve this problem? (Choose two.)

Question19: You are having management connectivity problems with a mixed-mode Virtual Chassis.
Which statement is correct in this scenario?

Question20:
Referring to the exhibit, VMs on Server-1 are sending traffic to VMs on Server-2. All VCPs in the VCF have
40Gbps of bandwidth available and automatic fabric trunking is bundling multiple VCPs together.
Which statement is correct in this scenario?

Question21:
Referring to the exhibit, what is the MAC address of the IRB interface on router PE1?

Question22: You are deploying an EVPN service between your data centers to enable Layer 2 stretch and Virtual Machine Traffic Optimization (VMTO) operations. You want to minimize the recovery time in the event of a failure.
In this scenario, which action must be performed on the IRB interface to accomplish this task?

Question23: What are two methods used to scale an IBGP IP Fabric? (Choose two.)

Question24:
Referring to the VCF shown in the exhibit, what is the remote destination trunk weight for the SW-4, SW-1, SW-5 path?

Question25: You created an IP Fabric based on IBGP. You noticed that ECMP load sharing is not working.
In this scenario, what is the problem?

Question26:
Referring to the exhibit, which two MAC addresses are learned from the local side of the MC-LAG link?

Question27: You are performing an in-service software upgrade (ISSU) on an QFX5100 Series device.
Which two statements are correct in this scenario? (Choose two.)

Question28: You are configuring VXLAN on a network of QFX5100s, and are using the set vlans vlan100 vxlan unreachable-vtep-aging-timer 600command.
What does this command do?

Question29: Which two technologies provide Layer 2 services across data centers in two remote locations? (Choose two.)

Question30:
The exhibit shows an output from a QFX5100 Series switch serving as an MC-LAG peer.
Which two statements are true in this scenario? (Choose two.)

Question31: You are building a mixed-mode Virtual Chassis with two QFX5100-24Qs, four QFX3500-48s, two EX4600-
