Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 111

Which two query types does a client make to a DNS server? (Choose two.)

Answer options

• A. Inverse
• B. PTR
• C. AAAA
• D. ACK
• E. DISCOVER

Correct answer: B, C

Explanation

The correct answers are B (PTR) and C (AAAA) because these are specific types of DNS queries used for resolving domain names to IP addresses and vice versa. Options A (Inverse) and D (ACK) are not standard DNS query types, and E (DISCOVER) is related to DHCP, not DNS.
