An administrator configures the following DNS records in the forward lookup zone acme.local: • A host (A) record with a blank name pointing to IP address 10.10.10.20 • A host (A) record named webserver pointing to IP address 10.10.10.30 • An alias (CNAME) record named www pointing to target host webserver.acme.local Which of the following statements accurately describes this configuration? Select all that apply.

The lab adds a host record with a blank name and address `10.10.10.20`, which represents the zone apex `acme.local`. It then adds `webserver` with address `10.10.10.30`. Finally, it creates the alias `www` targeting `webserver.acme.local`. No record assigns `10.10.10.40` to `www`; that address is intentionally useful as a test case for a name or address that has not been configured. **Key takeaway:** Read each DNS entry as a specific mapping; do not infer records that were never created.\n\n**Glossary:** **Zone apex**: The root name of a DNS zone. **CNAME**: An alias pointing to another canonical DNS name. **Target host**: The name to which an alias points.
