A network administrator is configuring DNS resource records for a newly deployed service hostname `app.example.com`. The service requires mapping the domain directly to an IPv6 address and publishing domain ownership verification text. A diagnostic `dig` command yields the following output:
;; QUESTION SECTION:
;app.example.com. IN ANY
;; ANSWER SECTION:
app.example.com. 3600 IN A 192.0.2.45
Which TWO of the following DNS record types must the administrator add to the authoritative zone file to satisfy these technical requirements?
- AAAA recordCevap
- TXT recordCevap
- CPTR record
- DSRV record
- ECNAME record
Cevap
The administrator must add an AAAA record to resolve the hostname to an IPv6 address and a TXT record to publish domain ownership verification text.
To satisfy both requirements, an AAAA record is required to map the hostname to its corresponding 128-bit IPv6 address, and a TXT record is required to hold the domain verification text string.
