Question 1

Which two statements are true for IPSec VPN? (Choose two.)



Answer : B, C

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.

Question 2

When collecting support bundles through NSX Manager, which files should be excluded for potentially containing sensitive information?



Answer : C

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.


Core files and Audit logs might contain sensitive information such as passwords or encryption keys. https://docs.vmware.com/en/VMware-NSX/4.1/administration/GUID-73D9AF0D-4000-4EF2-AC66-6572AD1A0B30.html

Question 3

Which TraceFlow traffic type should an NSX administrator use tor validating connectivity between App and DB virtual machines that reside on different segments?



Answer : B

Unicast is the traffic type that an NSX administrator should use for validating connectivity between App and DB virtual machines that reside on different segments.According to the VMware documentation1, unicast traffic is the traffic type that is used to send a packet from one source to one destination.Unicast traffic is the most common type of traffic in a network, and it is used for applications such as web browsing, email, file transfer, and so on2.To perform a traceflow with unicast traffic, the NSX administrator needs to specify the source and destination IP addresses, and optionally the protocol and related parameters1.The traceflow will show the path of the packet across the network and any observations or errors along the way3. The other options are incorrect because they are not suitable for validating connectivity between two specific virtual machines.Multicast traffic is the traffic type that is used to send a packet from one source to multiple destinations simultaneously2.Multicast traffic is used for applications such as video streaming, online gaming, and group communication4.To perform a traceflow with multicast traffic, the NSX administrator needs to specify the source IP address and the destination multicast IP address1.Broadcast traffic is the traffic type that is used to send a packet from one source to all devices on the same subnet2. Broadcast traffic is used for applications such as ARP, DHCP, and network discovery.To perform a traceflow with broadcast traffic, the NSX administrator needs to specify the source IP address and the destination MAC address as FF:FF:FF:FF:FF:FF1. Anycast traffic is not a valid option, as it is not supported by NSX Traceflow. Anycast traffic is a traffic type that is used to send a packet from one source to the nearest or best destination among a group of devices that share the same IP address. Anycast traffic is used for applications such as DNS, CDN, and load balancing.


Question 4

Refer to the exhibit.

An administrator would like to change the private IP address of the NAT VM I72.l6.101.il to a public address of 80.80.80.1 as the packets leave the NAT-Segment network.

Which type of NAT solution should be implemented to achieve this?



Answer : B

SNAT stands for Source Network Address Translation. It is a type of NAT that translates the source IP address of outgoing packets from a private address to a public address.SNAT is used to allow hosts in a private network to access the internet or other public networks1

In the exhibit, the administrator wants to change the private IP address of the NAT VM 172.16.101.11 to a public address of 80.80.80.1 as the packets leave the NAT-Segment network. This is an example of SNAT, as the source IP address is modified before the packets are sent to an external network.

According to the VMware NSX 4.x Professional Exam Guide, SNAT is one of the topics covered in the exam objectives2

To learn more about SNAT and how to configure it in VMware NSX, you can refer to the following resources:

Question 5

Which CLI command does an NSX administrator run on the NSX Manager to generate support bundle logs if the NSX UI Is inaccessible?



Answer : D

To generate the support bundle logs on the NSX Manager via API, the NSX administrator needs to use the POST method with the URL https://nsxmgr_ip/api/1.0/appliance-management/techsupportlogs/NSX, where nsxmgr_ip is the IP address of the NSX Manager1. This will create a tech support bundle file with a name like vcpnv.tgz.To download the generated tech support bundle file via CLI, the NSX administrator needs to use the get support-bundle file vcpnv.tgz command on the NSX Manager1. The other commands are incorrect because they either do not generate or download the support bundle logs, or they are not related to the NSX Manager.


Question 6

Which two steps must an NSX administrator take to integrate VMware Identity Manager in NSX to support role-based access control? (Choose two.)



Answer : C, E

https://docs.vmware.com/en/VMware-NSX-T-Data-Center/3.2/administration/GUID-EAAD1FBE-F750-4A5A-A3BF-92B1E7D016FE.html


Question 7

As part of an organization's IT security compliance requirement, NSX Manager must be configured for 2FA (two-factor authentication).

What should an NSX administrator have ready before the integration can be configured? O



Answer : B

To configure NSX Manager for two-factor authentication (2FA), an NSX administrator must have VMware Identity Manager (vIDM) with an OAuth Client added. vIDM provides identity management services and supports various 2FA methods, such as VMware Verify, RSA SecurID, and RADIUS. An OAuth Client is a configuration entity in vIDM that represents an application that can use vIDM for authentication and authorization. NSX Manager must be registered as an OAuth Client in vIDM before it can use 2FA.Reference: : VMware NSX-T Data Center Installation Guide, page 19. : VMware NSX-T Data Center Administration Guide, page 102.: VMware Blogs: Two-Factor Authentication with VMware NSX-T
