3V0-41.22 Practice Exam Questions and Answers

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 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 /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 troubleshoot the bridge configuration and restore access to the application, 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 select the overlay segment that is bridged to the VLAN-backed port group. For example, select Web-01 segment that you created in Task 2.
• Click Bridge > Set and verify the configuration details of the bridge. Check for any discrepancies or errors in the parameters such as bridge name, bridge ID, VLAN ID, edge node, etc.
• If you find any configuration errors, click 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 overlay segment and the VLAN-backed port group. You can use ping or traceroute commands from the NSX Edge CLI or the vSphere Web Client to test the connectivity. You can also use show service bridge command to check the status of the bridge 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 vSphere Distributed Switch.
• After resolving the issues, verify that the bridge is functioning and the Bridge-VM is responding to ICMP requests from the main console.You can also check the MAC addresses learned by the bridge on both sides of the network using show service bridge mac command on the NSX Edge CLI.

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.
