NEW QUESTION # 37
What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
- A. Group
- B. Segment Port
- C. Segment
- D. Tier-1 Gateway
- E. DFW
Answer: A,C
Explanation:
Explanation
C). Segment. This is correct. A segment is a logical construct that represents a layer 2 broadcast domain and a layer 3 subnet in NSX. A segment can be used to group and connect virtual machines, containers, or bare metal hosts that belong to the same application or service. A segment can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that enters or exits the segment12
E). Group. This is correct. A group is a logical construct that represents a collection of objects in NSX, such as segments, segment ports, virtual machines, IP addresses, MAC addresses, tags, or security policies. A group can be used to define dynamic membership criteria based on various attributes or filters. A group can also be used as the scope of a distributed firewall rule, which means that the rule will apply to all the traffic that matches the group membership criteria32
NEW QUESTION # 38
What can the administrator use to identify overlay segments in an NSX environment if troubleshooting is required?
- A. Geneve ID
- B. Segment ID
- C. VNI ID
- D. VIAN ID
Answer: C
Explanation:
According to the VMware NSX Documentation1, a segment is mapped to a unique Geneve segment that is distributed across the ESXi hosts in a transport zone. The Geneve segment uses a virtual network identifier (VNI) as an overlay network identifier. The VNI ID can be used to identify overlay segments in an NSX environment if troubleshooting is required.
NEW QUESTION # 39
Which two choices are use cases for Distributed Intrusion Detection? (Choose two.)
- A. Quarantine workloads based on vulnerabilities.
- B. Use agentless antivirus with Guest Introspection.
- C. Gain Insight about micro-segmentation traffic flows.
- D. Identify risk and reputation of accessed websites.
- E. Identify security vulnerabilities in the workloads.
Answer: A,E
Explanation:
Explanation
According to the VMware NSX Documentation, these are two of the use cases for Distributed Intrusion Detection, which is a feature of NSX Network Detection and Response:
* Quarantine workloads based on vulnerabilities: You can use Distributed Intrusion Detection to detect vulnerabilities in your workloads and apply quarantine actions to isolate them from the network until they are remediated.
* Identify security vulnerabilities in the workloads: You can use Distributed Intrusion Detection to scan your workloads for known vulnerabilities and generate reports that show the severity, impact, and remediation steps for each vulnerability.
NEW QUESTION # 40
Which three NSX Edge components are used for North-South Malware Prevention? (Choose three.)
- A. Security Hub
- B. IDS/IPS
- C. Security Analyzer
- D. Thin Agent
- E. Reputation Service
- F. RAPID
Answer: B,E,F
Explanation:
The answer is B, D, and F.
B) RAPID. This is correct. RAPID stands for Real-time Anti-malware Protection with Intelligent Detection. It is a component of the NSX Edge node that provides malware prevention for the north-south traffic. RAPID extracts files from the network traffic and analyzes them for malicious behavior using hash-based detection, local analysis, and cloud analysis techniques1 D) IDS/IPS. This is correct. IDS/IPS stands for Intrusion Detection and Prevention System. It is a component of the NSX Edge node that provides intrusion detection and prevention for the north-south traffic. IDS/IPS monitors the network traffic and compares it against a known set of signatures that specify patterns for different types of network intrusions. IDS/IPS can generate alerts or block the traffic based on the matching signatures and the configured actions2 F) Reputation Service. This is correct. Reputation Service is a component of the NSX Edge node that provides reputation-based filtering for the north-south traffic. Reputation Service uses a cloud-based database of known malicious IP addresses and domains to block or allow the traffic based on the reputation score of the source or destination. Reputation Service can also integrate with third-party reputation providers to enhance the security coverage3 A) Thin Agent. This is incorrect. Thin Agent is not a component of the NSX Edge node, but rather a component of the NSX Guest Introspection platform that runs on the virtual machine endpoints in the distributed east-west traffic. Thin Agent enables communication between the virtual machines and the NSX Manager, and facilitates malware prevention and intrusion detection on the host level.
C) Security Hub. This is incorrect. Security Hub is not a component of the NSX Edge node, but rather a component of the VMware Cloud Services platform that provides a unified view of security posture across multiple cloud environments. Security Hub integrates with NSX Advanced Threat Prevention to collect and display security events, alerts, and recommendations from NSX IDS/IPS and NSX Malware Prevention features.
E) Security Analyzer. This is incorrect. Security Analyzer is not a real product name or component name related to NSX Edge or NSX Advanced Threat Prevention. It is a fictional name that does not exist in the VMware portfolio.
To learn more about NSX Edge components for North-South Malware Prevention, you can refer to the following resources:

- A. Audit Files
- B. Core Files
- C. Controller Files
- D. Management Files
Answer: A,B
Explanation:
According to the VMware NSX Documentation1, core files and audit logs can contain sensitive information and should be excluded from the support bundle unless requested by VMware technical support. Controller files and management files are not mentioned as containing sensitive information.
NEW QUESTION # 45
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
* WKS-WEB-SRV-XXX
* WKY-APP-SRR-XXX
* WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A. Create an Ethernet based security policy.
- B. Use Edge as a firewall between tiers.
- C. Do a service insertion to accomplish the task.
- D. Group all by means of tags membership.
Answer: D
Explanation:
Explanation
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1 In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers. The naming convention will be:
* WKS-WEB-SRV-XXX
* WKY-APP-SRR-XXX
* WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2 Using tags membership has several advantages over the other options:
* It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3
* It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
* It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.
To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to the following resources:
* VMware NSX Documentation: Security Tag 1
* VMware NSX Micro-segmentation Day 1: Chapter 4 - Security Policy Design 2
* VMware NSX 4.x Professional: Security Groups
* VMware NSX 4.x Professional: Security Policies

- A. Read
- B. Full Access
- C. LB Operator
- D. Auditor
- E. None
- F. Enterprise Admin
- G. Network Admin
Answer: A,C,D,G
Explanation:
Explanation
According to the VMware NSX Documentation, these are four of the NSX built-in role-based access control (RBAC) roles:
* Network Admin: This role has full access to all NSX features and functions, such as creating and managing segments, gateways, firewall rules, load balancers, VPNs, and more.
* Read: This role has read-only access to all NSX features and functions, such as viewing segments, gateways, firewall rules, load balancers, VPNs, and more.
* LB Operator: This role has limited access to only the load balancer features and functions, such as creating and managing load balancer pools, virtual servers, monitors, and profiles.
* Auditor: This role has read-only access to only the audit logs and reports of NSX features and functions, such as viewing system events, alarms, statistics, and compliance.
NEW QUESTION # 47
Which CLI command shows syslog on NSX Manager?
- A. show log manager follow
- B. get log-file syslog
- C. /var/log/syslog/syslog.log
- D. get log-file auth.lag
Answer: B
Explanation:
According to the VMware NSX CLI Reference Guide, this CLI command shows the syslog messages on the NSX Manager node. You can use this command to view the system logs for troubleshooting or monitoring purposes.
The other options are either incorrect or not available for this task. get log-file auth.log is a CLI command that shows the authentication logs on the NSX Manager node, not the syslog messages. /var/log/syslog/syslog.log is not a CLI command, but a file path that may contain syslog messages on some Linux systems, but not on the NSX Manager node. show log manager follow is not a valid CLI command, as there is no show log command or manager option in the NSX CLI.
NEW QUESTION # 48
Which of the two following characteristics about NAT64 are true? (Choose two.)
- A. NAT64 is supported on Tier-1 gateways only.
- B. NAT64 requires the Tier-1 gateway to be configured in active-active mode.
- C. NAT64 requires the Tier-1 gateway to be configured in active-standby mode.
- D. NAT64 is stateless and requires gateways to be deployed in active-standby mode.
- E. NAT64 is supported on Tier-0 and Tier-1 gateways.
Answer: B,E
Explanation:
Explanation
NAT64 is a type of NAT that allows IPv6-only hosts to communicate with IPv4-only hosts by translating the IPv6 addresses to IPv4 addresses and vice versa.
C: NAT64 is supported on Tier-0 and Tier-1 gateways. This is stated in the first result1, which says
"Three types of NAT are supported, in addition to NAT64."
E: NAT64 requires the Tier-1 gateway to be configured in active-active mode. This is implied by the third result2, which says "Stateful NAT is not supported in active-active mode." Since NAT64 is stateless, it can be supported in active-active mode.
NEW QUESTION # 49
Which VPN type must be configured before enabling a L2VPN?
- A. SSL-bosed IPSec VPN
- B. Route-based IPSec VPN
- C. Policy based IPSec VPN
- D. Port-based IPSec VPN
Answer: B
Explanation:
Explanation
According to the VMware NSX Documentation, this VPN type must be configured before enabling a L2VPN.
L2VPN stands for Layer 2 VPN and is a feature that allows you to extend your layer 2 network across different sites using an IPSec tunnel. Route-based IPSec VPN is a VPN type that uses logical router ports to establish IPSec tunnels between sites.

The Evaluation form factor supports only NSX Intelligence, which provides network visibility and analytics for NSX-T environments2. The Standard form factor supports both NSX Intelligence and NSX Network Detection and Response, which provides network threat detection and response capabilities for NSX-T environments3. The Advanced form factor supports all four features: NSX Intelligence, NSX Network Detection and Response, NSX Malware Prevention, and NSX Metrics1.
NEW QUESTION # 51
Where in the NSX UI would an administrator set the time attribute for a time-based Gateway Firewall rule?
- A. The option to set time-based rule is a clock Icon in the policy.
- B. The option to set time based rule is a field in the rule Itself.
- C. The option to set time-based rule is a clock Icon in the rule.
- D. There Is no option in the NSX UI. It must be done via command line interface.
Answer: A
Explanation:
Explanation
According to the VMware documentation1, the clock icon appears on the firewall policy section that you want to have a time window. By clicking the clock icon, you can create or select a time window that applies to all the rules in that policy section. The other options are incorrect because they either do not exist or are not related to the time-based rule feature. There is no option to set a time-based rule in the rule itself, as it is a policy-level setting. There is also an option to set a time-based rule in the NSX UI, so it does not require using the command line interface.
NEW QUESTION # 52

- A. Through the OVF command line tool
- B. Through the NSXUI
- C. Through the vSphere Web Client
- D. Through automated or Interactive mode using an ISO
Answer: B
Explanation:
Through the NSX UI. According to the VMware NSX Documentation2, you can deploy NSX Edge nodes as virtual appliances through the NSX UI by clicking Add Edge Node and providing the required information. The other options are either outdated or not applicable for virtual NSX Edge nodes.
NEW QUESTION # 53
Which statement is true about an alarm in a Suppressed state?
- A. An alarm can be suppressed for a specific duration in hours.
- B. An alarm can be suppressed for a specific duration in seconds.
- C. An alarm can be suppressed for a specific duration in days.
- D. An alarm can be suppressed for a specific duration in minutes.
Answer: A
Explanation:
The answer is D. An alarm can be suppressed for a specific duration in hours.
According to the VMware NSX documentation, an alarm can be in one of the following states: Open, Acknowledged, Suppressed, or Resolved12 An alarm in a Suppressed state means that the status reporting for this alarm has been disabled by the user for a user-specified duration12 When a user moves an alarm into a Suppressed state, they are prompted to specify the duration in hours. After the specified duration passes, the alarm state reverts to Open. However, if the system determines the condition has been corrected, the alarm state changes to Resolved13 To learn more about how to manage alarm states in NSX, you can refer to the following resources:
VMware NSX Documentation: Managing Alarm States 1

NEW QUESTION # 54
NSX improves the security of today's modern workloads by preventing lateral movement, which feature of NSX can be used to achieve this?
- A. Network Segmentation
- B. Virtual Security Zones
- C. Dynamic Routing
- D. Edge Firewalling
Answer: A
Explanation:
According to the web search results, network segmentation is a feature of NSX that improves the security of today's modern workloads by preventing lateral movement. Lateral movement is a technique used by attackers to move from one compromised system to another within a network, exploiting vulnerabilities or credentials . Network segmentation prevents lateral movement by dividing a network into smaller segments or zones, each with its own security policies and controls. This way, if one segment is compromised, the attacker cannot access other segments or resources . NSX enables network segmentation by using micro-segmentation, which applies granular firewall rules at the virtual machine level, regardless of the physical network topology .
NEW QUESTION # 55
Which three DHCP Services are supported by NSX? (Choose three.)
- A. Segment DHCP
- B. DHCP Relay
- C. Port DHCP per VNF
- D. Gateway DHCP
- E. VRF DHCP Server
Answer: A,B,D
Explanation:
Explanation
According to the VMware NSX Documentation1, NSX-T Data Center supports the following types of DHCP configuration on a segment:
* Local DHCP server: This option creates a local DHCP server that has an IP address on the segment and provides dynamic IP assignment service only to the VMs that are attached to the segment.
* Gateway DHCP server: This option is attached to a tier-0 or tier-1 gateway and provides DHCP service to the networks (overlay segments) that are directly connected to the gateway and configured to use a gateway DHCP server.
* DHCP Relay: This option relays the DHCP client requests to the external DHCP servers that can be in any subnet, outside the SDDC, or in the physical network.
NEW QUESTION # 56
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. Disable Preemptive
- B. Preemptive
- C. Non-Preemptive
- D. Enable Preemptive
Answer: C
Explanation:
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 # 57
When configuring OSPF on a Tler-0 Gateway, which three of the following must match in order to establish a neighbor relationship with an upstream router? (Choose three.)
- A. Area ID
- B. Address of the neighbor
- C. Subnet mask
- D. Naming convention
- E. Protocol and Port
- F. MTU of the Uplink
Answer: A,C,F
Explanation:
ccording to the VMware NSX Documentation, these are the three parameters that must match in order to establish an OSPF neighbor relationship with an upstream router on a tier-0 gateway:
MTU of the Uplink: The maximum transmission unit (MTU) of the uplink interface must match the MTU of the upstream router interface. Otherwise, OSPF packets may be fragmented or dropped, causing neighbor adjacency issues.
Subnet mask: The subnet mask of the uplink interface must match the subnet mask of the upstream router interface. Otherwise, OSPF packets may not reach the correct destination or be rejected by the upstream router.
Area ID: The area ID of the uplink interface must match the area ID of the upstream router interface. Otherwise, OSPF packets may be ignored or discarded by the upstream router.
