Ingrid P.May 6, 2026The answer is B, SRV. Citrix email-based auto discovery works by having the Receiver or Workspace app query DNS for a service record in the format _citrixreceiver._tcp.yourdomain.com, and that SRV record points to the StoreFront FQDN on port 443, so the client resolves the store automatically when a user types their email address. MX is for routing email to mail servers, CNAME is just an alias, and CERT stores cryptographic certificates in DNS, none of which give the client a service endpoint to locate StoreFront. This is a card worth making: front side is "what DNS record type does Citrix email-based auto discovery require and what is the record name format," back side is "SRV, _citrixreceiver._tcp.domain, port 443, target is StoreFront FQDN" because the exam will sometimes give you the scenario without using the word SRV and expect you to recognize the pattern.
Mei-Ling H.May 8, 2026Good add on the flashcard, and worth noting the domain portion of that SRV name must match the domain suffix of the email address the user types, so if the user enters [email protected] the client queries _citrixreceiver._tcp.subsidiary.com, not the parent domain, which is the kind of scenario detail the exam uses to trip people up.
Lena V.Apr 23, 2026Took me a second on this one because I almost second-guessed myself toward CNAME, but the SRV record is what StoreFront email-based discovery actually needs, since it lets the client resolve both the hostname and port for the discovery service in a single lookup. On my exam I remembered the Citrix docs specifically calling out the _citrixreceiver._tcp SRV record format and that locked it in.
Mei-Ling H.May 8, 2026SRV is correct, but do you know what the actual record name format is?
Yusuf A.May 10, 2026Yeah, that tripped me up too, the format is _service._proto.name so something like _sip._tcp.example.com, with those underscores in front being required or the record just gets ignored.
Yusuf A.Apr 19, 2026I went with C, CERT, because my senior told me that when you're tying email identity to a service discovery process, the DNS layer needs to carry some kind of certificate or credential record so the client can validate the StoreFront endpoint it lands on, and CERT felt like the only option that made sense in that security context. Maybe I'm overthinking it but MX is just for mail routing, SRV felt too generic, and CNAME is just an alias so none of those seem specific enough for what StoreFront auto discovery is actually doing.
Mei-Ling H.Apr 21, 2026Yusuf, I see where you were going but StoreFront auto-discovery relies on a DNS SRV record because SRV is the record type designed to advertise a specific service, port, and host all in one entry, which is exactly what the Receiver or Workspace app queries to locate the StoreFront endpoint from the email domain. CERT sounds security-related but it stores cryptographic certificates in DNS, not service location data, so it does not fit the discovery mechanism here.
