Which of the following statements are correct about the PKI system structure?
- A. A PKI entity is an end user of PKI products or services. It can be an individual, an organization, a device such as a router or firewall, or a process running on a computer.
- B. A CA is a trusted entity that issues and manages digital certificates.
- C. CAs are classified into the root CA and subordinate CAs according to the hierarchy of CAs.
- D. A PKI system consists of three parts: entity, certificate authority, and certificate registration authority.
Answer: A,B,C,D
Explanation:
Explanation From HCIA-Security documents:
All four statements describe standard PKI roles and structure. A PKI entity is any certificate holder or relying participant that uses PKI services, which includes people, organizations, network devices, servers, and even application processes, so A is correct. PKI trust is commonly built using a CA hierarchy, where the root CA anchors trust and subordinate CAs issue certificates under the root's authority, so B is correct. The CA is the core trusted component that signs (issues) certificates and manages their lifecycle activities such as renewal, suspension or revocation publication, and certificate status services, so C is correct. In many enterprise implementations, the PKI system is presented as three major roles: entities that request/use certificates, the RA that performs identity verification and approval of requests, and the CA that issues certificates based on validated requests, so D is also correct.

NEW QUESTION # 34
Devices that need to provide network services externally, such as WWW servers and FTP servers, can be placed in the DMZ.
- A. TRUE
- B. FALSE
Answer: A
Explanation:
This statement is TRUE . A DMZ is a special security zone used to place servers that must provide services to external users while still being isolated from the internal trusted network. Typical examples include WWW servers, FTP servers, mail servers, and DNS servers . These systems need to be accessible from outside networks such as the Internet, but placing them directly inside the internal network would increase security risk.
The purpose of the DMZ is to create a buffer area between the Untrust zone and the Trust zone. External users can be allowed to access the public-facing servers in the DMZ according to security policies, while access from the DMZ to the internal network can be more strictly restricted. This design helps reduce the chance that an attacker who compromises a public server can directly reach sensitive internal systems.
On Huawei firewalls, the DMZ is one of the default security zones and is specifically intended for such semi- public service devices. Therefore, devices that provide external network services, such as WWW and FTP servers, can correctly be deployed in the DMZ .
