How to determine whether a DMARC record exists, or not?

mx flag

A quick search at mxtoolbox.com shows:

Category    Host    Result  
dmarc   example.com     No DMARC Record found    More Info
spf     example.com     No SPF Record found      More Info
mx      example.com     No DMARC Record found    More Info
mx      example.com     DMARC Quarantine/Reject policy not enabled   More Info
dns     example.com     SOA Expire Value out of recommended range    More Info

for a particular domain (not "example.com" obviously).

I was seeing that to lookup DMARC records, for example, with dig the syntax is like:

dig TXT  _dmarc.example.com

But how is the existence of a DMARC record established from dig?

According this support topic How to Use dig/nslookup to Find SPF, DKIM and DMARC Records for a Domain? from CISCO, the syntax to use dig to look up DMARC status is:

dig _dmarc.domain txt

Substitute domain with the domain you want to look up.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
