CompTIA A+ Certification Exam: Core 2 認定 220-1202 試験問題 (Q122-Q127):

質問 # 122
Which of the following depends on system time accuracy to function properly?

A. Terminal Access Controller Access-control System
B. Wi-Fi Protected Access
C. Remote Authentication Dial-in User Service
D. Kerberos token

正解：D

解説：
Kerberos relies on accurate system time to validate authentication tickets, as it uses time- stamped tokens with strict expiration windows to prevent replay attacks. If system clocks are not synchronized, authentication fails.

質問 # 123
Which of the following is the best reason for a network engineering team to provide a help desk technician with IP addressing information to use on workstations being deployed in a secure network segment?

A. The network allow list is set to a specific address.
B. DHCP services are not enabled for this subnet.
C. Only specific DNS servers are allowed outbound access.
D. NAC servers only allow for security updates to be installed.

正解：B

解説：
When a subnet does not offer DHCP, workstations cannot automatically obtain IP configuration.
Supplying help desk technicians with the correct static IP address, subnet mask, gateway, and DNS ensures the newly deployed machines can communicate on the secure network segment without relying on DHCP.

質問 # 124
A user ' s application only works with a legacy version of the OS. The OS is reaching its end-of-life date. For security reasons, the company is migrating to the current version of the OS. Which of the following is the most efficient way to complete the migration while maintaining accessibility to the application?

A. Terminal server
B. Virtualization
C. Bare-metal server
D. Multiboot

正解：B

解説：
Virtualizationallows the legacy OS to be run in a virtual machine (VM) on top of the newer OS. This method provides backward compatibility without requiring outdated operating systems on physical hardware.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"Using virtualization is a preferred method when legacy applications are needed after migrating to newer operating systems. It allows legacy environments to exist securely within a modern OS framework."

質問 # 125
Which of the following threats is shoulder surfing an example of?

A. Social engineering
B. Evil twin
C. Brute-force
D. Zero-day

正解：A

A. Remote monitoring and management
B. Remote Desktop Protocol
C. Virtual private network
D. File Transfer Protocol

正解：C

解説：
A virtual private network provides secure, encrypted remote access to internal resources across both Linux and Windows systems, making it the best choice for remote users connecting from home.
