CompTIA A+ Certification Exam: Core 2 Sample Questions (Q85-Q90):NEW QUESTION # 85
A technician is troubleshooting a PC that is unable to perform DNS lookups. Utilizing the following firewall output:
Protocol/Port        Action        Direction
1         Allow        Out
445         Block        Out
53         Block        Out
123         Block        Out
80         Block        Out
Which of the following ports should be opened to allow for DNS recursion?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
  • E. 4
Answer: E
Explanation:
DNS (Domain Name System) lookups are essential for translating human-friendly domain names into IP addresses that computers use to communicate. DNS typically uses port 53 for its communication.
In the provided firewall output, various ports are either allowed or blocked for outgoing traffic. For DNS recursion, which is the process of resolving domain names to IP addresses, port 53 must be open.
Port 53: This is the standard port used by DNS for queries and responses. The fact that it is currently blocked (as per the firewall output) is the reason why DNS lookups are failing. Opening port 53 will allow the DNS requests to pass through the firewall, enabling the resolution of domain names to IP addresses.
Other ports mentioned in the output are used for different services and protocols:
Port 1 is generally not used for standard services.
Port 445 is associated with SMB (Server Message Block) for file sharing in Windows environments.
Port 123 is used by NTP (Network Time Protocol) for time synchronization.
Port 80 is used for HTTP traffic, which is web traffic but not related to DNS lookups.

NEW QUESTION # 86
A technician is deploying a new Wi-Fi solution for the office and wants to ensure users can log in to the Wi-Fi with their existing network log-in and password. Which of the following methods should the technician use?
  • A. RADIUS
  • B. TKIP
  • C. AES
  • D. WPA3
Answer: A
Explanation:
Detailed
RADIUS (Remote Authentication Dial-In User Service) (Option B) is a network protocol that allows users to authenticate using their network credentials, such as usernames and passwords, typically stored in a central directory like Active Directory. It ensures that users can log in to the Wi-Fi using their existing network credentials.
AES (Option A) is an encryption standard but does not handle authentication.
TKIP (Option C) is a deprecated encryption protocol and not related to network login management.
WPA3 (Option D) is the latest Wi-Fi security standard but does not specifically handle centralized login management like RADIUS does.
CompTIA A+ Core 2 Reference:
2.2 - Compare and contrast wireless security protocols and authentication methods, including RADIUS.

Answer: A
Explanation:

Encrypting the laptop's hard drive will ensure that any sensitive data stored on the laptop is secure, even if the laptop is lost or stolen.

This is an important security measure for any laptop used by an employee who travels, as it helps to protect the data stored on the laptop from unauthorized access.

NEW QUESTION # 89
A technician is reimaging a desktop PC. The technician connects the PC to the network and powers it on. The technician attempts to boot the computer via the NIC to image the computer, but this method does not work. Which of the following is the MOST likely reason the computer is unable to boot into the imaging system via the network?
  • A. The computer's CMOS battery failed.
  • B. The PXE boot option has not been enabled
  • C. The computer's NIC is faulty.
  • D. The Ethernet cable the technician is using to connect the desktop to the network is faulty.
Answer: B
Explanation:
The most likely reason the computer is unable to boot into the imaging system via the network is that the PXE boot option has not been enabled. PXE (Preboot Execution Environment) is an environment that allows computers to boot up over the network, instead of from a local disk. In order for this to work, the PXE boot option must be enabled in the computer's BIOS settings. As stated in the CompTIA A+ Core 2 exam objectives, technicians should know how to enable PXE in BIOS to enable network booting on a computer.
