When deploying an NSX Edge Transport Node, what two valid IP address assignment options should be specified for the TEP IP addresses? (Choose two.)
Correct Answer:
AD
When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the u assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345.

Which two of the following features are supported for the Standard NSX Application Platform Deployment? (Choose two.)
Correct Answer:
CD
The NSX Application Platform Deployment features are divided into three form factors: Evaluation, Standard, and Advanced. Each form factor determines which NSX features can be activated or installed on the platform1. 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.

What needs to be configured on a Tler-0 Gateway lo make NSX Edge Services available to a VM on a VLAN-backed logical switch?
Correct Answer:
B
To make NSX Edge Services available to a VM on a VLAN-backed logical switch, you need to configure
a VLAN Uplink on the Tier-0 Gateway. A VLAN Uplink is a logical interface that connects the Tier-0 Gateway to the physical network and provides external connectivity for the NSX Edge Services1. A VLAN Uplink can be configured on the NSX Manager UI by selecting Networking > Tier-0 Gateways > Interfaces > Set > Add Interface1.

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?
Correct Answer:
C
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
Which NSX CLI command is used to change the authentication policy for local users?
Correct Answer:
D
According to the VMware NSX Documentation4, the set auth-policy command is used to change the authentication policy settings for local users, such as password length, lockout period, and maximum authentication failures. The other commands are either used to view the authentication policy settings (B), change the CLI session timeout (A), or change the hardening policy settings ©.
