VMware Advanced Deploy VMware NSX-T Data Center 3.x 3V0-41.22 Exam Dumps: Updated Questions & Answers (October 2025)

To configure the NSX backups for the environment, you need to follow these steps:

Verify that an SFTP server is available on the network and obtain SFTP fingerprint. You can use thesearch_web("SFTP server availability")tool to find some information on how to set up and check an SFTP server. You can also use thessh-keyscancommand to get the fingerprint of the SFTP server. For example,ssh-keyscan -t ecdsa sftp_serverwill return the ECDSA key of the sftp_server. You can compare this key with the one displayed on the NSX Manager UI when you configure the backup settings.

Configure NSX Backups via NSX Appliance Backup. Log in to the NSX Manager UI with admin credentials. The default URL is https:// . Select System > Lifecycle Management > Backup & Restore. Click Edit under the SFTP Server label to configure your SFTP server. Enter the FQDN or IP address of the backup file server, such as 10.10.10.100. The protocol text boxis already filled in. SFTP is the only supported protocol. Change the default port if necessary. The default TCP port is 22. In the Directory Path text box, enter the absolute directory path where the backups will be stored, such as /data. The directory must already exist and cannot be the root directory (/). Avoid using path drive letters or spaces in directory names; they are not supported. In the Passphrase text box, enter a passphrase that will be used to encrypt and decrypt the backup files, such as VMware1!. Click Save to create the backup configuration.

Configure Scheduling Criteria. On the Backup & Restore page, click Edit under the Schedule label to configure your backup schedule. Select Enabled from the drop-down menu to enable scheduled backups. Select Daily from the Frequency drop-down menu to run backups once every 24 hours. Select a time from the Time drop-down menu to specify when the backup will start, such as 12:00 AM. Select Enabled from the Additional Backup Trigger drop-down menu to run backups when there are changes published to the NSX environment. Click Save to create the backup schedule.

Verify that a backup file has been created on the SFTP server. On the Backup & Restore page, click Start Backup to run a manual backup and verify that it completes successfully. You should see a message saying “Backup completed successfully”. You can also check the status and details of your backups on this page, such as backup size, duration, and timestamp.Alternatively, you can log in to your SFTP server and check if there is a backup file in your specified directory path, such as /data.

To run the GET call in the API using Postman and save the output to the desktop to a text file called API.txt, you need to follow these steps:

Open Postman and create a new request tab. Select GET as the method from the drop-down menu.

Enter the URL of the NSX-T Policy API endpoint for retrieving the BGP routing table, such as https:// /policy/api/v1/infra/tier-0s/vmc/routing-table?enforcement_point_path=/infra/sites/default/enforcement-points/vmc-enforcementpoint

Click the Authorization tab and select Basic Auth as the type from the drop-down menu. Enter your NSX-T username and password in the Username and Password fields, such as admin and VMware1!.

Click Send to execute the request and view the response in the Body tab. You should see a JSON object with the BGP routing table information, such as routes, next hops, prefixes, etc.

Click Save Response and select Save to a file from the drop-down menu. Enter API.txt as the file name and choose Desktop as the location. Click Save to save the output to your desktop.

You have successfully run the GET call in the API using Postman and saved the output to your desktop to a text file called API.txt.

To create a custom QoS profile to prioritize the traffic on the phoenix-VLAN segment and limit the rate of ingress traffic, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https:// .

Navigate to Networking > Segments > Switching Profiles and click Add Switching Profile. Select QoS as the profile type.

Enter a name and an optional description for the QoS profile, such as phoenix-QoS.

In the Mode section, select Untrusted as the mode from the drop-down menu. This will allow you to set a custom DSCP value for the outbound IP header of the traffic on the segment.

In the Priority section, enter 46 as the DSCP value. This will mark the traffic with Expedited Forwarding (EF) per-hop behavior, which is typically used for high-priority applications such as voice or video.

In the Class of Service section, enter 5 as the CoS value. This will map the DSCP value to a CoS value that can be used by VLAN-based logical ports or physical switches to prioritize the traffic.

In the Ingress section, enter 1000000 as the Average Bandwidth in Kbps. This will limit the rate of inbound traffic from the VMs to the logical network to 1 Mbps.

Optionally, you can also configure Peak Bandwidth and Burst Size settings for the ingress traffic, which will allow some burst traffic above the average bandwidth limit for a short duration.

Click Save to create the QoS profile.

Navigate to Networking > Segments and select the phoenix-VLAN segment that you want to apply the QoS profile to.

Click Actions > Apply Profile and select phoenix-QoS as the switching profile that you want to apply to the segment.

Click Apply to apply the profile to the segment.

You have successfully created a custom QoS profile and applied it to the phoenix-VLAN segment.

To deploy three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment, you need to follow these steps:

Log in to the NSX Manager UI with admin credentials. The default URL is https:// .

Navigate to Networking > Segments and click Add Segment.

Enter a name for the segment, such as Web-01.

Select Tier-1 as the connectivity option and choose an existing tier-1 gateway from the drop-down menu or create a new one by clicking New Tier-1 Gateway.

Enter the gateway IP address of the subnet in a CIDR format, such as 192.168.10.1/24.

Select an overlay transport zone from the drop-down menu, such as Overlay-TZ.

Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs.

Click Save to create the segment.

Repeat steps 2 to 8 for the other two overlay-backed segments, such as App-01 and DB-01, with different subnet addresses, such as 192.168.20.1/24 and 192.168.30.1/24.

To create a VLAN-backed segment, click Add Segment again and enter a name for the segment, such as Legacy-01.

Select Tier-0 as the connectivity option and choose an existing tier-0 gateway from the drop-down menu or create a new one by clicking New Tier-0 Gateway.

Enter the gateway IP address of the subnet in a CIDR format, such as 10.10.10.1/24.

Select a VLAN transport zone from the drop-down menu, such as VLAN-TZ, and enter the VLAN ID for the segment, such as 100.

Optionally, you can configure advanced settings such as DHCP, Metadata Proxy, MAC Discovery, or QoS for the segment by clicking Set Advanced Configs.

Click Save to create the segment.

To apply a segment security profile to block DHCP requests on the segments, navigate to Networking > Segments > Segment Profiles and click Add Segment Profile.

Select Segment Security as the profile type and enter a name and an optional description for the profile.

Toggle the Server Block and Server Block - IPv6 buttons to enable DHCP filtering for both IPv4 and IPv6 traffic on the segments that use this profile.

Click Save to create the profile.

Navigate to Networking > Segments and select the segments that you want to apply the profile to.

Click Actions > Apply Profile and select the segment security profile that you created in step 18.

Click Apply to apply the profile to the selected segments.

You have successfully deployed three layer 2 overlay-backed segments and one layer 2 VLAN-backed segment with DHCP filtering using NSX-T Manager UI.
