NEW QUESTION # 45
Which of the following is not an application scenario for PKI?
- A. SSL VPN
- B. Web login through HTTPS
- C. IPv6 SEND
- D. IPsec VPN
Answer: D
Explanation:
Explanation From HCIA-Security documents:
PKI is mainly used where digital certificates are needed to prove identity, distribute public keys safely, and support functions such as authentication, encryption, and digital signatures . HTTPS web login relies on server certificates (and sometimes client certificates) to build trust and establish encrypted sessions, so D is a classic PKI scenario. SSL VPN also typically uses certificates for gateway identity and often for user/device authentication, so A fits PKI usage as well. IPv6 SEND Secure Neighbor Discovery uses cryptographic mechanisms (such as CGA and signature-based protection) that depend on certificates, making C another PKI- related scenario.
By contrast, IPsec VPN does not necessarily depend on PKI in all deployments. IPsec can authenticate peers using pre-shared keys or other methods without certificates, so it is commonly treated as not strictly a PKI application scenario in basic classification questions. In many training outlines, PKI scenarios are highlighted as HTTPS, SSL VPN, and IPv6 SEND, while IPsec is presented as a separate VPN technology that may or may not integrate certificates. Therefore, the best answer is B .
