2V0-21.23 Question 189
Select 3You are deploying a new VMware vCenter Server Appliance (VCSA) in your environment. During the deployment, you need to ensure that the appliance has proper DNS resolution and network connectivity to function correctly. Which of the following steps should you perform to ensure a successful deployment?
- A
Verify that forward and reverse DNS records are properly configured for the VCSA hostname.
- B
Assign the VCSA a static IP address or configure a DHCP reservation for consistent IP allocation.
- C
Directly connect the VCSA to the ESXi host's management network without using a port group.
- D
Ensure that the NTP server is reachable and configured to synchronize the VCSA's time during deployment.
- E
Disable the firewall on the ESXi host where the VCSA will be deployed to avoid connectivity issues.
Show answer and explanation
Correct answers: A, B, D
Explanation
Deploying the VMware vCenter Server Appliance (VCSA) requires careful attention to DNS configuration, IP address assignment, and time synchronization. Proper forward and reverse DNS resolution ensures seamless communication, while a static IP or DHCP reservation provides consistent network identification. Synchronizing time with an NTP server prevents issues related to time-sensitive operations. Avoiding incorrect practices, such as disabling firewalls or bypassing port groups, is critical to maintain network security and stability.
- A. Correct.
Proper forward and reverse DNS resolution are critical for the VCSA to communicate with other systems in the environment and to avoid issues during deployment.
- B. Correct.
Assigning a static IP or using a DHCP reservation ensures consistent IP allocation, which is necessary for the VCSA to maintain stable network connectivity.
- C. Incorrect.
Directly connecting the VCSA to the ESXi host's management network without using a port group is not a recommended practice. The VCSA should be connected to an appropriate port group for proper network segmentation and communication.
- D. Correct.
Time synchronization with an NTP server is essential for the VCSA to operate correctly, as time discrepancies can lead to issues with authentication and logs.
- E. Incorrect.
It is not recommended to disable the firewall on the ESXi host. Instead, proper firewall rules should be configured to allow necessary traffic.
