Q51. 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
Q52. Where is the layer 2 bridge instance deployed when configuring a bridge connection between a logical switch and a VLAN?
A. On the ESXi host running the logical router
B. On the ESXi host running the logical switch
C. On both ESXi hosts that make up the layer 2 bridge
D. On each virtual machine that will utilize the layer 2 bridge
Q53. An administrator configures the IPSec VPN service on an NSX Edge instance, but the negotiation fails. Examining the log file, the administrator notices the following messagE. INVALID_ID_INFORMATION Which misconfiguration caused the error?
A. Pre-shared key (PSK) does not match.
B. Diffie-Hellman (DH) Group does not match.
C. Perfect Forward Secrecy (PFS) does not match.
D. VPN tunnel address is incorrect.
Q54. 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?
Q55. An administrator wishes to control traffic flow between two virtual machines. The virtual machines are in the same subnet, but are located on separate ESXi hosts. The administrator deploys an Edge Firewall to one of the hosts and verifies the default firewall rule is set to deny, but the two virtual machines can still communicate with each other. What task will correct this issue?
A. Configure both ESXi host firewalls to deny traffic from the virtual machine on the other host.
B. Deploy another Edge Firewall on the host running the second virtual machine.
C. Remove any other firewall appliances that may exist on either of the ESXi hosts.
D. Deploy a Distributed Firewall with firewall rules to prevent traffic between the virtual machines.

A. vSphere Web Client -> Networking & Security -> Installation -> Service Deployments tab
B. vSphere Web Client -> Networking & Security -> Service Composer -> Service Deployments tab
C. vSphere Web Client -> Networking & Security -> Service Definitions
D. vSphere Web Client -> Networking & Security -> Distributed Firewall -> Service Definitions
Q57. Which component automates the consumption of third-party services and provides mapping to virtual machines using a logical policy?
A. NSX Manager
B. Cloud Management Platform (CMP)
C. Service Composer
D. NSX Data Security
Q58. A company wants to deploy VMware NSX for vSphere and ensure the least amount of bandwidth consumption in the underlying physical architecture. Which replication mode should the logical switches be deployed with?
A. Multicast Replication Mode
B. Unicast Replication Mode
C. Hybrid Replication Mode
D. vSphere Replication Mode
Q59. Layer 2 Multipathing (L2MP) and Multi-chassis Etherchannel (MEC) features have distinct scaling differences with the network switching and routing services provided by NSX. Which two statements provide a proper contrast of these services? (Choose two.)
A. Multi-chassis Etherchannel features provide higher utilization of Ethernet links within a defined L2/L3 distribution area.
B. Multi-Chassis Etherchannel features provide an easy ability to scale a VLAN across the data center.
C. NSX provides a method to transparently deploy L2MP protocols upon existing data center installations without service disruption.
D. NSX provides a method to deploy scalable L2/L3 services on existing data center installations.
Answer: A, D
Q60. A vSphere administrator added a new interface to a Distributed Router with a subnet of 172.16.10.0/24 and wants to make this subnet reachable to the rest of the network. How can the vSphere administrator achieve this?
A. Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and redistribute into OSPF the 172.16.10.0/24 subnet.
B. Enable OSPF on the Distributed Router. Configure the uplink interface in the normal area and the new interface with the subnet 172.16.10.0/24 in a Backbone area.
C. Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and redistribute from OSPF the 172.16.10.0/24 subnet.
D. Enable OSPF on the Distributed Router. Configure the uplink interface in the Backbone area and the new interface with the subnet 172.16.10.0/24 in a normal area.
