NEW QUESTION 2
Which of the following settings must be configured in an NSX environment before enabling stateful active-active SNAT?
- A. Tier-1 gateway in active-standby mode
- B. Tier-1 gateway in distributed only mode
- C. An Interface Group for the NSX Edge uplinks
- D. A Punting Traffic Group for the NSX Edge uplinks
Answer: C
Explanation:
To enable stateful active-active SNAT on a Tier-0 or Tier-1 gateway, you must configure an Interface Group for the NSX Edge uplinks. An Interface Group is a logical grouping of NSX Edge interfaces that belong to the same failure domain. A failure domain is a set of NSX Edge nodes that share the same physical network infrastructure and are subject to the same network failures. By configuring an Interface Group, you can ensure that the stateful services are distributed across different failure domains and can recover from network failures1
NEW QUESTION 3
Which two statements are true about IDS Signatures? (Choose two.)
- A. Users can upload their own IDS signature definitions.
- B. An IDS signature contains data used to identify known exploits and vulnerabilities.
- C. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
- D. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- E. An IDS signature contains a set of instructions that determine which traffic is analyzed.
Answer: BE
Explanation:
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker’s attempt to exploit a known vulnerability in both the operating system and applications. This implies that statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic. This implies that statement E is
true. Statement A is false because users cannot upload their own IDS signature definitions, they have to use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the following severity categories: Critical, High, Medium, Low, or Informational1.

NEW QUESTION 8
Which statement is true about an alarm in a Suppressed state?
- A. An alarm can be suppressed for a specific duration in seconds.
- B. An alarm can be suppressed for a specific duration in days.
- C. An alarm can be suppressed for a specific duration in minutes.
- D. An alarm can be suppressed for a specific duration in hours.
Answer: D
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:

An NSX administrator Is treating a NAT rule on a Tler-0 Gateway configured In active-standby high availability mode. Which two NAT rule types are supported for this configuration? (Choose two.)
- A. Reflexive NAT
- B. Destination NAT
- C. 1:1 NAT
- D. Port NAT
- E. Source NAT
Answer: BE
Explanation:
According to the VMware NSX Documentation, these are two NAT rule types that are supported for a tier-0 gateway configured in active-standby high availability mode. NAT stands for Network Address Translation and is a feature that allows you to modify the source or destination IP address of a packet as it passes through a gateway.
Destination NAT: This rule type allows you to change the destination IP address of a packet from an external IP address to an internal IP address. You can use this rule type to provide access to your internal servers from external networks using public IP addresses. Source NAT: This rule type allows you to change the source IP address of a packet from an internal IP address to an external IP address. You can use this rule type to provide access to external networks from your internal servers using public IP addresses.
NEW QUESTION 11
What are two valid options when configuring the scope of a distributed firewall rule? (Choose two.)
- A. DFW
- B. Tier-1 Gateway
- C. Segment
- D. Segment Port
- E. Group
Answer: CE
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 12
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. Use Edge as a firewall between tiers.
- B. Do a service insertion to accomplish the task.
- C. Group all by means of tags membership.
- D. Create an Ethernet based security policy.
Answer: C
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
NEW QUESTION 13
Which two statements are true for IPSec VPN? (Choose two.)
- A. VPNs can be configured on the command line Interface on the NSX manager.
- B. IPSec VPN services can be configured at Tler-0 and Tler-1 gateways.
- C. IPSec VPNs use the DPDK accelerated performance library.
- D. Dynamic routing Is supported for any IPSec mode In NSX.
Answer: BC
Explanation:
According to the VMware NSX 4.x Professional documents and tutorials, IPSec VPN secures traffic flowing between two networks connected over a public network through IPSec gateways called endpoints. NSX Edge supports a policy-based or a route-based IPSec VPN. Beginning with NSX-T Data Center 2.5, IPSec VPN services are supported on both Tier-0 and Tier-1 gateways1. NSX Edge also leverages the DPDK accelerated performance library to optimize the performance of IPSec VPN2.
NEW QUESTION 14
An NSX administrator would like to create an L2 segment with the following requirements:
• L2 domain should not exist on the physical switches.
• East/West communication must be maximized as much as possible.
Which type of segment must the administrator choose?
- A. VLAN
- B. Overlay
- C. Bridge
- D. Hybrid
Answer: B
Explanation:
An overlay segment is a layer 2 broadcast domain that is implemented as a logical construct in the NSX-T Data Center software. Overlay segments do not require any configuration on the physical switches, and they allow for optimal east/west communication between workloads on different ESXi hosts. Overlay segments use the Geneve protocol to encapsulate and decapsulate traffic between the hosts. Overlay segments are created and managed by the NSX Manager.

NEW QUESTION 15
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. Naming convention
- B. MTU of the Uplink
- C. Subnet mask
- D. Address of the neighbor
- E. Protocol and Port
- F. Area ID
Answer: BCF
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.
