At ValidExamDumps, we consistently monitor updates to the VMware 3V0-41.22 exam questions by VMware. Whenever our team identifies changes in the exam questions, objectives, focus areas or requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these up to date and 100% exam domain coverage questions, our customers can successfully pass the VMware Advanced Deploy VMware NSX-T Data Center 3.x exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by VMware in their 3V0-41.22 exam. These outdated questions lead to customers failing their VMware Advanced Deploy VMware NSX-T Data Center 3.x exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions. Our main priority is your success in the VMware 3V0-41.22 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

Task 2
You are asked to deploy three Layer 2 overlay-backed segments to support a new 3-tier app and one Layer 2 VLAN-backed segment for support of a legacy application. The logical segments must block Server DHCP requests. Ensure three new overlay-backed segments and one new VLAN-backed logical segment are deployed to the RegionA01-COPMOI compute cluster. All configuration should be done utilizing the NSX UI.
You need to:
Complete the requested task.
Notes: Passwords are contained in the user_readme.txt. Task 2 is dependent on the completion of Task 1. Other tasks are dependent on completion of this task. You may want to move to the next tasks while waiting for configuration changes to be applied. This task should take approximately 10 minutes to complete.
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://<nsx-manager-ip-address>.
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.

Task 13
You have been asked to configure the NSX backups for the environment so that if the NSX Manager fails it can be restored with the same IP address to the original primary Data Center that is in an Active / Standby configuration. Backups should be scheduled to run once every 24 hours as well as when there are changes published to the NSX environment. Ensure that backups are completed on their respective environment. Verify the backup file has been created on the SFTP server.
* Credentials needed to complete the task:
You need to:
* Verify that an SFTP server is available on the network and obtain SFTP Fingerprint.
* Configure NSX Backups via NSX Appliance Backup
* Configure Scheduling Criteria
Backup Configuration Criteria
Complete the requested task.
Notes: Passwords are contained in the user_readme.txt. This task is not dependent on other tasks. This task should take approximately 15 minutes to complete.
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 the search_web('SFTP server availability') tool to find some information on how to set up and check an SFTP server. You can also use the ssh-keyscan command to get the fingerprint of the SFTP server. For example, ssh-keyscan -t ecdsa sftp_server will 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://<nsx-manager-ip-address>. 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 box is 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 /dat
a. 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.

Complete the requested task.
Notes: Passwords are contained in the user_readme.txt. This task is not dependent on another. This task Should take approximately 15 minutes to complete.
To troubleshoot the NSX IPSec VPN service that has been reported down, you need to follow these steps:
Log in to the NSX Manager UI with admin credentials. The default URL is https://<nsx-manager-ip-address>.
Navigate to Networking > VPN > IPSec VPN and select the IPSec VPN session that is down. You can identify the session by its name, local endpoint, remote endpoint, and status.
Click Show IPSec Statistics and view the details of the IPSec VPN session failure. You can see the error message, the tunnel state, the IKE and ESP status, and the statistics of the traffic sent and received.
Compare the configuration details of the IPSec VPN session with the expected configuration as provided below. Check for any discrepancies or errors in the parameters such as local and remote endpoints, local and remote networks, IKE and ESP profiles, etc.
If you find any configuration errors, click Actions > Edit and modify the parameters accordingly. Click Save to apply the changes.
If you do not find any configuration errors, check the connectivity and firewall rules between the local and remote endpoints. You can use ping or traceroute commands from the NSX Edge CLI to test the connectivity. You can also use show service ipsec command to check the status of IPSec VPN service on the NSX Edge.
If you find any connectivity or firewall issues, resolve them by adjusting the network settings or firewall rules on the NSX Edge or the third-party device.
