Implementing _________ via identity certificates is a secure method to verify the identities of users and devices accessing network resources.

Question

Options

• Anetwork segmentation
• Bendpoint protection
• Cdata encryption
• Duser and device authentication

• A
  2% (1)
• B
  5% (2)
• C
  7% (3)
• D
  86% (37)

Explanation

User and device authentication (D) is correct because identity certificates - such as X.509/PKI certificates - are a standard mechanism for authenticating who a user is and what a device is before granting network access; this is the definition of authentication, not the other options. Network segmentation (A) is wrong because it divides a network into zones to limit lateral movement, but does not verify identity. Endpoint protection (B) refers to securing devices against malware and threats, not proving their identity. Data encryption (C) protects data confidentiality in transit or at rest, but does not establish who or what is connecting.

Memory tip: Think "certificates = ID cards" - just as a physical ID card proves your identity, a digital certificate proves a user's or device's identity. Authentication = "prove who you are," which is exactly what certificates do.
