City Guilds Model Questions Vol1 2019 Information Technology Question 19
Practice objective / multiple choice question 19 from the 2019 City Guilds Model Questions Vol1 Information Technology examination.
The authoritative name server for the domain \(example.com\) holds a CNAME record that maps \(example.com\) to \(www.example.com\) with a TTL of \(43200\) seconds, and an A record for \(www.example.com\) with IP address \(203.0.113.5\) and a TTL of \(86400\) seconds. A recursive resolver cached both records at exactly 12:00 PM. At 3:30 PM the resolver receives another query for \(example.com\). Assuming no other caching events, what IP address will be returned, and what are the remaining TTL values (in seconds) for the A record and the CNAME record at that moment?
