SIMULATION Task 9 TO prepare for Virtual machine migration from VLAN-backed port groups to an overlay segment in NSX. a test bridge has been configured. The bridge is not functioning, and the -Bridge-VM- is not responding to ICMP requests from the main console. You need to: * Troubleshoot the configuration and make necessary changes to restore access to the application. 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 IS minutes to complete.
정답:
See the Explanation part of the Complete Solution and step by step instructions Explanation: 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://<nsx-manager-ip-address>. 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.

SIMULATION 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.

See the Explanation part of the Complete Solution and step by step instructions Explanation: 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. 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.
