A university analyst inspects an object that shows a subject, an issuer, validity dates, and a subject alternative name, and the object does not include a private key. Which format family is this?
Select an answer to reveal the explanation.
Short Explanation
An identification card shows a name, an issuer, dates, and an alias, and it is not the pouch that also hides a house key. You are holding an X.509 certificate. The trap is calling those fields a cipher suite, a private-key bundle, or a flow template.
Full Explanation
Subject, issuer, validity, and subject alternative name are fields of an X.509 certificate. The object in front of the analyst shows those fields and does not include a private key, so the format family is the certificate itself. "An X.509 certificate, identified here by subject, issuer, validity dates, and a subject alternative name" matches the object. "A cipher suite string naming the algorithms negotiated for one TLS session" is an algorithm label and does not carry a subject or an issuer. "A PKCS#12 bundle, a store that also holds the matching private key material" can wrap a certificate together with a key, but this object has no private key. "A NetFlow template describing the fields carried in an exported flow record" describes flow columns, not certificate fields. Exam caveat: a key store can contain an X.509 certificate, and the fields listed here are still the certificate, not the store. Operational check: display the object and confirm subject, issuer, validity, and the subject alternative name, and confirm that no private key is included.
