Question: 9
An NSX administrator is creating a Tier-1 Gateway configured In Active-Standby High Availability Mode. In the
event of node failure, the failover policy should not allow the original tailed node to become the Active node upon
recovery.
Which failover policy meets this requirement?
A. Non-Preemptive
B. Preemptive
C. Enable Preemptive
D. Disable Preemptive
Answer: A
Explanation:
According to the VMware NSX Documentation, a non-preemptive failover policy means that the original failed node
will not become the active node upon recovery, unless the current active node fails again. This policy can help avoid
unnecessary failovers and ensure stability.
The other options are either incorrect or not available for this configuration. Preemptive is the opposite of non-
preemptive, meaning that the original failed node will become the active node upon recovery, if it has a higher priority
than the current active node. Enable Preemptive and Disable Preemptive are not valid options for the failover policy, as
the failover policy is a drop-down menu that only has two choices: Preemptive and Non-Preemptive.
Question: 10
A customer has a network where BGP has been enabled and the BGP neighbor is configured on the Tier-0 Gateway.
An NSX administrator used the get gateways command to retrieve this Information:
Which two commands must be executed to check BGP neighbor status? (Choose two.)
A. vrf 1
B. vrf 4
C. sa-nexedge-01(tier1_sr> get bgp neighbor
D. sa-nexedge-01(tier0_sr> get bgp neighbor
E. sa-nexedge-01(tier1_dr)> get bgp neighbor
F. vrf 3
Answer: B,D
Explanation:
According to the image that you sent, the BGP neighbor is configured on the tier-0 gateway with the UUID 9f8e3a7c-
5f9c-4d1a-bb6f-9c7f3d6f3d63 and the VRF ID 4. Therefore, to check the BGP neighbor status, you need to enter the
VRF context of 4 and execute the get bgp neighbor command on the tier-0 service router (SR) node.
The other options are either incorrect or not applicable for this scenario. vrf 1, vrf 3, and sa-nexedge-01(tier1_dr)> get
bgp neighbor are not related to the BGP neighbor configuration on the tier-0 gateway. sa-nexedge-01(tier1_sr> get bgp
neighbor is also not relevant, as there is no BGP neighbor configured on the tier-1 gateway.
Question: 11
Sort the rule processing steps of the Distributed Firewall. Order responses from left to right.

wrong
Answer: B,D
Question: 12
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB
virtual machines that reside on different segments?
A. Multicast
B. Unkrast
C. Anycast
D. Broadcast
Answer: C
Explanation:
According to the VMware NSX Documentation1, TraceFlow supports four types of traffic: Unicast, Broadcast,
Multicast, and Anycast. Unicast traffic is sent to a specific destination IP address. Broadcast traffic is sent to all hosts
on a network segment. Multicast traffic is sent to a group of hosts that have joined a multicast group. Anycast traffic is
sent to the nearest or best destination among a group of hosts that share the same IP address.
Anycast traffic is useful for validating connectivity between virtual machines that reside on different segments,
because it can test the routing and firewall rules that apply to the traffic. Anycast traffic can also help identify the
optimal path for the traffic based on factors such as latency, bandwidth, and load balancing.
Question: 13
Which two logical router components span across all transport nodes? (Choose two.)
A. SFRVICE_ROUTER_TJER0
B. TIERO_DISTRI BUTE D_ ROUTER
C. D1STRIBUTED_R0UTER_TIER1
D. DISTRIBUTED_ROUTER_TIER0
E. SERVICE_ROUTER_TIERl
Answer: B,C
Explanation:
According to the VMware NSX 4.x Professional documents and tutorials, NSX-T has two logical router components,
namely the Services Router (SR) and the Distributed Router (DR). As the names imply, SR is where centralized
services are provisioned such as NAT, DHCP, VPN, Perimeter Firewall, Load Balancing, etc., and DR performs
distributed routing across all hosts participating in a given transport zone3. The DR component is present in both Tier-
0 and Tier-1 logical routers, while the SR component is only present in Tier-1 logical routers or in active-standby
mode of Tier-0 logical routers4. Therefore, the logical router components that span across all transport nodes are
TIER0_DISTRIBUTED_ROUTER and DISTRIBUTED_ROUTER_TIER1.
Question: 14
Which command Is used to test management connectivity from a transport node to NSX Manager?
A)
B)
C)
D)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Explanation:
According to the web search results, the command that is used to test management connectivity from a transport node
to NSX Manager is get managers. This command displays the status, IP address, and thumbprint of the NSX Manager
that the transport node is connected to. It also shows the connection state, which can be UP or DOWN. If the
connection state is DOWN, it means that there is a problem with the management connectivity.
Question: 15

two.)
A. NSX Intrusion Detection and Prevention
B. NSX Intelligence
C. NSX Network Detection and Response
D. NSX Malware Prevention Metrics
E. NSX Intrinsic Security
Answer: C,E
Explanation:
According to the VMware NSX Documentation, these are two of the features that are supported for the Standard NSX
Application Platform Deployment:
- NSX Network Detection and Response: This feature provides advanced threat detection and response capabilities for
network and application security. It includes features such as Distributed Intrusion Detection and Prevention
(IDS/IPS), Web Reputation Analysis, File and Process Analysis, and NSX Advanced Threat Prevention.
- NSX Intrinsic Security: This feature provides built-in security for applications and workloads across clouds. It
includes features such as Distributed Firewall, Identity Firewall, Service Insertion, Micro-segmentation, and Policy-
based Automation.
Question: 16
Which is an advantages of a L2 VPN In an NSX 4.x environment?
A. Enables Multi-Cloud solutions
B. Achieve better performance
C. Enables VM mobility with re-IP
D. Use the same broadcast domain
Answer: D
Explanation:
L2 VPN is a feature of NSX that allows extending Layer 2 networks across different sites or clouds over an IPsec
tunnel. L2 VPN has an advantage of enabling VM mobility with re-IP, which means that VMs can be moved from one
site to another without changing their IP addresses or network configurations. This is possible because L2 VPN allows
both sites to use the same broadcast domain, which means that they share the same subnet and VLAN.
Question: 17
Which two CLI commands could be used to see if vmnic link status is down? (Choose two.)
A. esxcfg-nics -1
B. excli network nic list
C. esxcli network vswitch dvs wmare list
D. esxcfg-vmknic -1
E. esxcfg-vmsvc/get.network
Answer: A,B
Explanation:
esxcfg-nics -l and esxcli network nic list are two CLI commands that can be used to see the vmnic link status on an
ESXi host. Both commands display information such as the vmnic name, driver, link state, speed, and duplex mode.
The link state can be either Up or Down, indicating whether the vmnic is connected or not.
For example, the output of esxcfg-nics -l can look like this:
Name PCI Driver Link Speed Duplex MAC Address MTU Description
vmnic0 0000:02:00.0 igbn Up 1000Mbps Full 00:50:56:01:2a:3b 1500 Intel Corporation I350 Gigabit Network

Which command on ESXI is used to verify the Local Control Plane connectivity with Central Control Plane?
A)
B)
C)
D)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B
Explanation:
According to the web search results, the command that is used to verify the Local Control Plane (LCP) connectivity
with Central Control Plane (CCP) on ESXi is get control-cluster status. This command displays the status of the LCP
and CCP components on the ESXi host, such as the LCP agent, CCP client, CCP server, and CCP connection. It also
shows the IP address and port number of the CCP server that the LCP agent is connected to. If the LCP agent or CCP
client are not running or not connected, it means that there is a problem with the LCP connectivity.
Question: 19
An NSX administrator wants to create a Tler-0 Gateway to support equal cost multi-path (ECMP) routing.
Which failover detection protocol must be used to meet this requirement?
A. Bidirectional Forwarding Detection (BFD)
B. Virtual Router Redundancy Protocol (VRRP)
C. Beacon Probing (BP)
D. Host Standby Router Protocol (HSRP)
Answer: A
Explanation:
According to the VMware NSX 4.x Professional documents and tutorials, BFD is a failover detection protocol that
provides fast and reliable detection of link failures between two routing devices. BFD can be used with ECMP routing
to monitor the health of the ECMP paths and trigger a route change in case of a failure12. BFD is supported by both
BGP and OSPF routing protocols in NSX-T3. BFD can also be configured with different timers to achieve different
detection times3.
Question: 20

A. From VMware Identity Manager the status of the remote access application must be green.
B. From the NSX UI the status of the VMware Identity Manager Integration must be "Enabled".
C. From the NSX CLI the status of the VMware Identity Manager Integration must be "Configured".
D. From the NSX UI the URI in the address bar must have "locaNfatse" part of it.
Answer: B
Explanation:
From the NSX UI the status of the VMware Identity Manager Integration must be âEnabledâ. According to the
VMware NSX Documentation1, after configuring VMware Identity Manager integration, you can validate the
functionality by checking the status of the integration in the NSX UI. The status should be âEnabledâ if the integration
is successful. The other options are either incorrect or not relevant.
