Before starting the installation of the vCenter Server Appliance, the administrator must complete the following actions: C. Create a reverse DNS A record for the vCenter Server (vcsa01). A reverse DNS A record associates an IP address with a hostname. Creating this record ensures that the IP address 172.20.10.100 resolves to the hostname vcsa01.corp.local. E. Create a forward DNS A record for the vCenter Server (vcsa01). A forward DNS A record maps a hostname to an IP address. Creating this record ensures that the hostname vcsa01.corp.local resolves to the IP address 172.20.10.100. These actions ensure proper DNS resolution for the vCenter Server Appliance during installation. Therefore, the correct actions to complete before starting the installation are C and E.

CE is the correct answer. A & B are CNAME records, which are aliases...useless. D is to exclude too, having a DNS record for the ESXi host is not necessary for vCenter deployment.

To use an FQDN for the appliance system name, make sure the FQDN can be resolved by a DNS server. Add forward and reverse DNS A records for verification. https://docs.vmware.com/en/VMware-vSphere/8.0/vsphere-vcenter-upgrade/GUID-752FCA83-1A9B-499E-9C65-D5625351C0B5.html#GUID-24D34C53-B00E-47B7-92A7-6B0155DF6889__GUID-D5BC40DF-91CA-4B56-A041-BFCED5FA2806:~:text=If%20you%20plan%20to%20use%20an%20FQDN%20for%20the%20appliance%20system%20name%2C%20you%20must%20verify%20that%20the%20FQDN%20is%20resolvable%20by%20a%20DNS%20server%2C%20by%20adding%20forward%20and%20reverse%20DNS%20A%20records.
