Answer: A
Q3. -- Exhibit --
-- Exhibit --An NSX administrator is examining an error in the Event Console as shown in the Exhibit.
Which condition would result in this error?
A. The configured MTU size on the physical network is too small.
B. The VTEP IP pool addresses are on the ESXi management network subnet.
C. VLANs are configured on the logical network.
D. A VXLAN segment ID pool is not configured.
Answer: B
Q4. Which statement best describes scaling a fault tolerant spine-leaf multipathing fabric architected for an NSX deployment?
A. Scaling should be performed by replacing 1Gbps links in the architecture with 10Gbps links.
B. Scaling should be performed by increasing the number of links from each leaf switch to the associated spine switches in the architecture.
C. Scaling should be performed by increasing the number of spine switches while maintaining point-to-point connectivity between leafs and spines.
D. Scaling should be performed by using layer 2 switching between the leaf and spine switches.
Answer: C
Q5. Based on VMware's best practices, what two statements define the best solution for scaling layer 2 services for the virtual network? (Choose two.)
A. Employ a layer 2 switched network.
B. Employ a layer 3 switched network.
C. Use GRE for an overlay network.
D. Use VXLAN for an overlay network.
Answer: B, D
Q6. What are two advantages for using NSX for vSphere's Logical Switching? (Choose two.)
A. Expands the number of available VLANs.
B. Allows for Layer 2 switching over Layer 3 infrastructure.
C. Distributes Layer 3 data across multiple hypervisors
D. Provides for 10,000 logical segments.
Answer: B, D
Q7. A company wants to deploy VMware NSX for vSphere with no PIM and no IGMP configured in the underlying physical network. This company also must ensure that non- ESXi hosts do not receive broadcast, unknown unicast or multicast (BUM) traffic. Which replication mode should the logical switches be deployed with?
A. Unicast Replication Mode B. Multicast Replication Mode C. Hybrid Replication Mode
D. Transport Zone Mode
Answer: A
Q8. Which two NSX Data Security roles could be assigned to view configured policies and violation reports? (Choose two.)

B. Default Port
C. Number of backups retained
D. Filename prefix
Answer: A, D
Q11. Which two actions take place when an active NSX Edge instance fails? (Choose two.)
A. Once the original NSX Edge instance is recovered, it preempts the other NSX Edge instance and takes over the active role.
B. The standby NSX Edge instance becomes the active instance and requests routing updates from the routing neighbors.
C. Once the original NSX Edge instance is recovered, the NSX Manager attempts to place it on a different host from the other NSX Edge instance.
D. The standby NSX Edge instance becomes the active instance and retains any routing neighbor adjacencies.
Answer: C, D
Q12. -- Exhibit --An administrator has configured an NSX network as shown in the Exhibit. Both VM-A and VM-B use the same Distributed Router for their default gateway. Based on the exhibit, if VM-A sends a packet to VM-B,what happens to the packet before it reaches VM-B?
A. Distributed Router in Host-A receives the packet from VM-A and forwards it to Logical Switch 7775 in Host-B, via a VXLAN frame, which delivers it to VM-B.
B. Logical Switch 7321 in Host-A receives the packet inside a frame from VM-A and forwards it to Logical Switch 7775 in Host-B, via a VXLAN frame, which delivers it to VM-
B.
C. Distributed Router in Host-A receives the packet from VM-A and forwards it to Logical Switch 7321 in Host-B, via a VXLAN frame, which delivers it to Logical Switch 7775 before it is delivered to VM-B.
D. Logical Switch 7321 in Host-A receives the packet from VM-A and forwards it to the Distributed Router in Host-B, which passes it along to Logical Switch 7775 in Host-B before it is delivered to VM-B.
Answer: A
