Version: 3Refer to the exhibit. A developer runs a keytool command and sees the output above. Which command produced this output?
⚠ Common exam trap
Candidates often confuse `-list -v` (which shows keystore entry details) with `-printcert` (which shows certificate file details), or mistakenly think `-exportcert` or `-importcert` produce verbose console output.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
keytool -list -v -alias mykey -keystore keystore.jks
The `keytool -list -v -alias mykey -keystore keystore.jks` command displays detailed certificate information (including owner, issuer, serial number, validity, and fingerprint) for the specified alias in the JKS keystore. The `-v` flag produces verbose output, which matches the exhibit's detailed certificate listing.
