Q11. 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
Q12. What is required before running an Activity Monitoring report?
A. Enable data collection on the NSX Controller.
B. Enable data collection on the vCenter Server.
C. Enable data collection on the NSX Manager.
D. Enable data collection on the virtual machine.
Q13. Where are the distributed NSX firewall decisions logged?
A. NSX Manager
B. vCenter Server
C. NSX Edge
D. ESXi host
Q14. -- Exhibit --Your data center clusters are configured as shown in the exhibit. Core0 uses Virtual SAN and hosts virtual machines running the following components:
. vCenter Server
. Single Sign-On Server
. Update Manager
. SQL Server database Core1, Core2, and Core3 use a single Fibre Channel attached storage array. Core1 hosts over 500 virtual machines. Core2 hosts over 400 virtual machines. Core3 hosts 100 virtual machines. Following VMware's best practices, NSX Controller components should be deployed to which location(s)?
A. Deploy three NSX Controllers, one on each host of Core0.
B. Deploy four NSX controllers, one on each cluster in the data center.
C. Deploy 27 NSX controllers, one for each host in the data center
D. Deploy three NSX controllers. Deploy one in Core1, one in Core2, and one in Core3.
Q15. Your data center is made up of two VMware vCenter Server instances. Each vCenter Server manages three clusters with 16 hosts per cluster. In preparing for your VMware NSX deployment, how many vShield Endpoint instances will you have?
Q16. Which two characteristics of the underlying physical network does VMware NSX require for robust IP transport? (Choose two.)
A. The physical network should provide scalable network I/O using Layer 2 Multipathing (L2MP) and Multichassis Link Aggregation (MLAG).
B. The physical network should provide scalable network I/O using Equal Cost Multipathing (ECMP).
C. QoS is not necessary since classification and marking will be done in the overlay.
D. QoS classification and marking is required to provide end-to-end flow control.
Answer: B, D
Q17. Which statement describes proper packet processing of layer 3 traffic in an NSX for vSphere topology?
A. All packets are processed by the distributed router. No packets are processed by the Logical Router Control VM.
B. Only packets requiring routing to another VM on the same host are processed by the distributed router. Other packets are processed by the Logical Router Control VM.
C. Only packets requiring routing to another VM on a different host are processed by the distributed router. Other packets are processed by the Logical Router Control VM.
D. All packets requiring routing are processed by performing a lookup in the Logical Router Control VM and then forwarded.
Q18. 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
Q19. When preparing a vSphere host cluster to work with VMware NSX, which two options show VIBs that are installed and registered with all hosts within the prepared cluster? (Choose two.)
A. NSX VXLAN
B. NSX Distributed Firewall
C. NSX Edge
D. NSX Data Security
Answer: A, B
Q20. Which NSX service or feature provides optimized management of virtual machine broadcast (ARP) traffic?
A. NSX Controller
B. NSX Manager
C. Edge Services Gateway
