Which two query types does a client send to a DNS server?

Choose two
  • A Inverse
  • B PTR
  • C AAAA
  • D ACK
  • E DISCOVER
Explanation

AAAA and PTR are DNS query types a client can request: AAAA obtains IPv6 address records, while PTR obtains pointer records used for reverse DNS resolution. Inverse (IQUERY) was an obsolete DNS operation, not a normal modern client lookup query; ACK and DISCOVER belong to DHCP.
