CCNA: Cisco Certified Network Associate — Question 516

Which two components comprise part of a PKI? (Choose two.)

Answer options

• A. preshared key that authenticates connections
• B. one or more CRLs
• C. RSA token
• D. CA that grants certificates
• E. clear-text password that authenticates connections

Correct answer: B, D

Explanation

The correct answers are B and D because a Certificate Revocation List (CRL) is essential for managing digital certificates within a Public Key Infrastructure (PKI), and the Certificate Authority (CA) is responsible for issuing those certificates. The other options, such as preshared keys and clear-text passwords, do not directly relate to the fundamental components of PKI.
