CompTIA A+ Certification Exam: Core 1 Sample Questions (Q172-Q177):

NEW QUESTION # 172
A technician is configuring a new CAD workstation that has four large hard drives. The workstation will be used to edit large, critical files, so the storage configuration should be both fast and redundant. Which of the following RAID levels BEST meets these requirements?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: D


NEW QUESTION # 173
Following a scheduled power outage, users report they cannot access the local intranet. A technician is able to ping the IP address of the server that is hosting the website. Which of the following serves is MOST likely offline?

  • A. DNS
  • B. DHCP
  • C. Web
  • D. File

Answer: A

Explanation:
DNS stands for Domain Name System and is a service that translates domain names (such as www.example.com) into IP addresses (such as 192.168.1.100) that computers can use to communicate over a network. If the DNS server is offline, users may not be able to access websites or other network resources by using their domain names, even if they are online and reachable by their IP addresses. The technician should check if the DNS server is running and configured correctly, or use an alternative DNS server if possible.

NEW QUESTION # 174
Which of the following ports allows for secure communications?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
Explanation
The correct answer is B. 22.
Port 22 is the default port for SSH (Secure Shell), a protocol that allows secure and encrypted remote login and command execution over a network. SSH uses public key cryptography to authenticate the client and the server, and to encrypt the data exchanged between them. SSH can be accessed through different ports, depending on the configuration of the server and the client. The default port for SSH is 22, but it can be changed to any other port for security reasons1.
Port 20 is the default port for FTP (File Transfer Protocol) data transfer, a protocol that allows file transfer between a client and a server over a network. FTP uses two ports: one for data transfer (port 20) and one for control commands (port 21). FTP does not provide encryption or authentication, and it is vulnerable to various attacks, such as packet sniffing, spoofing, or brute force. To secure FTP connections, protocols such as FTPS (FTP over SSL) or SFTP (SSH File Transfer Protocol) can be used2.
Port 23 is the default port for Telnet, a protocol that allows remote login and command execution over a network. Telnet does not provide encryption or authentication, and it sends data in plain text, which can be easily intercepted or modified by attackers. Telnet is considered obsolete and insecure, and it should be replaced by SSH or other secure protocols3.
Port 25 is the default port for SMTP (Simple Mail Transfer Protocol), a protocol that allows sending and receiving email messages over a network. SMTP does not provide encryption or authentication, and it can be exploited by spammers or hackers to send malicious or unwanted emails. To secure SMTP connections, protocols such as SMTPS (SMTP over SSL) or STARTTLS (Transport Layer Security) can be used.
Therefore, port 22 is the only port that allows for secure communications by default, as it uses SSH protocol.
For more information about ports and their security, you can refer to the following web search results: How to secure your TCP/IP ports, What is an SSL port? A technical guide for HTTPS, HTTPS Port: What It Is, How to Use It, and More (2023).


NEW QUESTION # 175
A technician is asked to purchase and install a line-of-sight wireless system that provides a stable network connection between two buildings. Which of the following needs to be considered prior to purchasing the system?

  • A. Firewall rules
  • B. IP address range
  • C. Regulatory power limits
  • D. SSID broadcast

Answer: C

Explanation:
Explanation
A line-of-sight wireless system is a type of wireless communication that requires a clear and unobstructed path between the transmitter and the receiver. This can be achieved by using directional antennas that focus the radio signals in a narrow beam. A line-of-sight wireless system can provide a stable network connection between two buildings that are within the range and visibility of each other.
However, before purchasing and installing a line-of-sight wireless system, one of the factors that needs to be considered is the regulatory power limits. The power limit is the maximum amount of radio frequency (RF) energy that a transmitter can emit. Different countries and regions have different regulations and standards for the allowable power levels of wireless devices. Exceeding the power limit can cause interference with other wireless services, such as aviation, radio, television, etc. It can also pose health and safety risks to humans and animals.
Therefore, a technician should check the local laws and regulations for the power limits of the wireless system before buying and installing it. The technician should also use a proper tool to measure the actual power output of the transmitter and adjust it accordingly. The technician should also ensure that the transmitter and receiver are aligned properly and have a clear line of sight without any obstacles.
The other options are not relevant to the line-of-sight wireless system. The IP address range is a set of numerical identifiers that are assigned to devices on a network. It does not affect the physical transmission of wireless signals. The SSID broadcast is a feature that allows a wireless network to announce its name and availability to nearby devices. It does not affect the stability of the network connection between two buildings.
The firewall rules are a set of policies that control the incoming and outgoing traffic on a network. They do not affect the line-of-sight wireless system.

NEW QUESTION # 176
A large office is eliminating all personal primers for VIP staff members and replacing these devices with one enterprise MFP. Human resources staff members are concerned about printing confidential documents on the new device. Which of the following best addresses this concern?

  • A. Secure print
  • B. Audit logs
  • C. Wi-Fi direct printing
  • D. Central printer server

Answer: A

Explanation:
Secure print is the best option to address the concern of printing confidential documents on a shared enterprise multifunction printer (MFP). Secure print requires users to enter a PIN or use an copyright at the printer to release their print jobs. This ensures that documents are only printed when the user is physically present to collect them, preventing sensitive information from being left unattended or viewed by unauthorized individuals. While a central printer server, audit logs, and Wi-Fi direct printing have their own benefits, they do not provide the same level of immediate security for confidential documents as secure print does. A central printer server centralizes management but does not prevent unauthorized viewing. Audit logs provide a record of activity but do not prevent the initial security breach. Wi-Fi direct printing allows for a direct connection to the printer but does not secure the document during printing.
