NEW QUESTION # 23
An administrator has deployed 10 Edge Transport Nodes in their NSX Environment, but has forgotten to specify an NTP server during the deployment.
What is the efficient way to add an NTP server to all 10 Edge Transport Nodes?
- A. Use a Node Profile
- B. Use the CU on each Edge Node
- C. Use a PowerCU script
- D. Use Transport Node Profile
Answer: A
Explanation:
Explanation
A node profile is a configuration template that can be applied to multiple NSX Edge nodes or transport nodes at once. A node profile can include settings such as NTP server, DNS server, syslog server, and so on1. By using a node profile, an administrator can efficiently configure or update the network settings of multiple NSX Edge nodes or transport nodes in a single operation2. The other options are incorrect because they are either not efficient or not supported. Using the CLI on each Edge node would require manual and repetitive commands for each node, which is not efficient. Using a Transport Node Profile would not work, because a Transport Node Profile is used to configure the NSX-T Data Center components on a transport node, such as the transport zone, the N-VDS, and the uplink profiles3. Using a PowerCLI script might work, but it would require writing and testing a custom script, which is not as efficient as using a built-in feature like a node profile.

NEW QUESTION # 25
What are the four types of role-based access control (RBAC) permissions? (Choose four.)
- A. None
- B. Execute
- C. Auditor
- D. Enterprise Admin
- E. Network Admin
- F. Full access
- G. Read
Answer: A,B,F,G
Explanation:
Explanation
The four types of role-based access control (RBAC) permissions are Read, None, Full access, and Execute1.
Read permission allows the user to view the configuration and status of the system. None permission denies any access to the system. Full access permission grants all permissions including Create, Read, Update, and Delete (CRUD). Execute permission includes Read and Update permissions1. Auditor, Enterprise Admin, and Network Admin are not types of permissions, but types of roles that have different sets of permissions. References: NSX Features There are four types of permissions. Included in the list are the abbreviations for the permissions that are used in the Roles and Permissions and Roles and Permissions for Manager Mode tables.
Full access (FA) - All permissions including Create, Read, Update, and Delete Execute (E) - Includes Read and Update Read (R) None NSX-T Data Center has the following built-in roles. Role names in the UI can be different in the API.
In NSX-T Data Center, if you have permission, you can clone an existing role, add a new role, edit newly created roles, or delete newly created roles.

NEW QUESTION # 26
Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?
- A. Broadcast
- B. Anycast
- C. Multicast
- D. Unkrast
Answer: B
Explanation:
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.

NEW QUESTION # 30
What must be configured on Transport Nodes for encapsulation and decapsulation of Geneve protocol?
- A. UDP
- B. STT
- C. VXIAN
- D. TEP
Answer: D
Explanation:
According to the VMware NSX Documentation, TEP stands for Tunnel End Point and is a logical interface that must be configured on transport nodes for encapsulation and decapsulation of Geneve protocol. Geneve is a tunneling protocol that encapsulates the original packet with an outer header that contains metadata such as the virtual network identifier (VNI) and the transport node IP address. TEPs are responsible for adding and removing the Geneve header as the packet traverses the overlay network.
NEW QUESTION # 31
When a stateful service is enabled for the first lime on a Tier-0 Gateway, what happens on the NSX Edge node'
- A. SR is instantiated and automatically connected with DR.
- B. SR and DR Is instantiated but requites manual connection.
- C. DR Is instantiated and automatically connected with SR.
- D. SR and DR doesn't need to be connected to provide any stateful services.
Answer: A
Explanation:
The answer is A. SR is instantiated and automatically connected with DR.
SR stands for Service Router and DR stands for Distributed Router. They are components of the NSX Edge node that provide different functions1 The SR is responsible for providing stateful services such as NAT, firewall, load balancing, VPN, and DHCP. The DR is responsible for providing distributed routing and switching between logical segments and the physical network1 When a stateful service is enabled for the first time on a Tier-0 Gateway, the NSX Edge node automatically creates an SR instance and connects it with the existing DR instance. This allows the stateful service to be applied to the traffic that passes through the SR before reaching the DR2 According to the VMware NSX 4.x Professional Exam Guide, understanding the SR and DR components and their functions is one of the exam objectives3 To learn more about the SR and DR components and how they work on the NSX Edge node, you can refer to the following resources:
VMware NSX Documentation: NSX Edge Components 1
VMware NSX 4.x Professional: NSX Edge Architecture

- B. esxcfg-vmknic -1
- C. excli network nic list
- D. esxcfg-vmsvc/get.network
- E. esxcli network vswitch dvs wmare list
Answer: A,C
Explanation:
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:

- A. Compares the management plane configuration states containing control plane traffic and error reporting from transport node agents.
- B. Injects ICMP traffic into the data plane and observes the results in the control plane.
- C. Injects synthetic traffic into the data plane and observes the results in the control plane.
- D. Compares intended network state in the control plane with Tunnel End Point (TEP) keepalives in the data plane.
Answer: C
Explanation:
Explanation
The Traceflow tool identifies issues in a network by injecting synthetic traffic into the data plane and observing the results in the control plane. This allows the tool to identify any issues in the network and provide a detailed report on the problem. You can use the Traceflow tool to test connectivity between any two endpoints in your NSX-T Data Center environment.
NEW QUESTION # 34
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. Preemptive
- B. Enable Preemptive
- C. Non-Preemptive
- D. Disable Preemptive
Answer: C
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.
NEW QUESTION # 35
Which steps are required to activate Malware Prevention on the NSX Application Platform?
- A. Select Cloud Region and Deploy Network Detection and Response.
- B. Activate NSX Network Detection and Response and run Pre-checks.
- C. Select Cloud Region and run Pre-checks.
- D. Activate NSX Network Detection and Response and Deploy Malware Prevention.
Answer: C
Explanation:
Explanation
To activate Malware Prevention on the NSX Application Platform, the steps are:
In the NSX Manager UI, select System and in the Configuration section, select NSX Application Platform.
Navigate to the Features section, locate the NSX Malware Prevention feature card, and click Activate or anywhere in the card.
In the NSX Malware Prevention activation window, select one of the available cloud regions from which you can access the NSX Advanced Threat Prevention cloud service.
Click Run Prechecks. This precheck process can take some time as the system validates that the minimum license requirement is met and that it is eligible for use with the NSX Advanced Threat Prevention cloud service. The system also validates that the selected cloud region is reachable.
Click Activate. This step can take some time1. Therefore, the correct answer is D. The other options are incorrect because they involve activating or deploying NSX Network Detection and Response, which is a different feature from Malware Prevention. References: Activate NSX Malware Prevention

Refer to the exhibit.
An administrator configured NSX Advanced Load Balancer to load balance the production web server traffic, but the end users are unable to access the production website by using the VIP address.
Which of the following Tier-1 gateway route advertisement settings needs to be enabled to resolve the problem? Mark the correct answer by clicking on the image.
Answer:
Explanation:
Explanation
The correct answer is to enable the option All LB VIP Routes on the Tier-1 gateway route advertisement settings. This option allows the Tier-1 gateway to advertise the NSX Advanced Load Balancer LB VIP routes to the Tier-0 gateway and other peer routers, so that the end users can reach the production website by using the VIP address1. The other options are not relevant for this scenario.
To mark the correct answer by clicking on the image, you can click on the toggle switch next to All LB VIP Routes to turn it on. The switch should change from gray to blue, indicating that the option is enabled. See the image below for reference:
NEW QUESTION # 38
An administrator wants to validate the BGP connection status between the Tier-O Gateway and the upstream physical router.
What sequence of commands could be used to check this status on NSX Edge node?
- A. enable <LR-D>
get vrf <ID>
show bgp neighbor - B. set vrf <ID>
show logical-routers
show <LR-D> bgp - C. get gateways
vrf <number>
get bgp neighbor - D. show logical-routers
get vrf
show ip route bgp
Answer: C
Explanation:
Explanation
The sequence of commands that could be used to check the BGP connection status between the Tier-O Gateway and the upstream physical router on NSX Edge node is get gateways, vrf <number>, get bgp neighbor. These commands can be executed on the NSX Edge node CLI after logging in as admin6. The first command, get gateways, displays the list of logical routers (gateways) configured on the Edge node, along with their IDs and VRF numbers7. The second command, vrf <number>, switches to the VRF context of the desired Tier-O Gateway, where <number> is the VRF number obtained from the previous command7. The third command, get bgp neighbor, displays the BGP neighbor summary for the selected VRF, including the neighbor IP address, AS number, state, uptime, and prefixes received8. The other options are incorrect because they either use invalid or incomplete commands or do not switch to the correct VRF context.
