local network but is now hosted as a SaaS solution. Which of the following records should be used to
accomplish the task?
A imo, TXT records can hold extra info but aren’t used to redirect or alias names like CNAMEs. Since the goal is redirection, TXT and PTR don’t really fit here.
It’s D because CNAMEs are perfect for pointing an existing hostname to a new one, like a SaaS provider’s domain. A and AAAA only map names to IPs, so they don’t handle hostname redirection.
B tbh, AAAA records handle IPv6 addresses, so if the SaaS provides an IPv6 IP, you'd use this instead of CNAME. It’s a solid alternative if you’re dealing with IPs and not hostnames.
D Using a CNAME record is the simplest way to redirect requests from your old local resource name to the new SaaS domain, since it points one hostname to another directly.
Is there a specific DNS zone or domain mentioned where this redirection should happen? Also, does the SaaS use a different hostname or just a new IP? That might help decide if CNAME is the right choice.
