NEW QUESTION # 853
Which of the following network types is used for pairing a Bluetooth device to a smartphone?

A. WAN
B. MAN
C. PAN
D. LAN

Answer: C

Explanation:
A PAN, or Personal Area Network, is the network type that is used for pairing a Bluetooth device to a smartphone. A PAN is a network that connects personal devices, such as phones, tablets, laptops, headphones, speakers, or printers, over a short distance, usually less than 10 meters or 33 feet. A PAN can use wireless technologies, such as Bluetooth, Wi-Fi, or infrared, to enable communication and data exchange between the devices. A Bluetooth PAN, also known as a piconet, can consist of up to eight devices, one of which acts as the master and the others as slaves. The master device initiates the pairing process with the other devices and controls the data transmission. The devices use radio waves in the 2.4 GHz frequency band to communicate with each other. Bluetooth is a low-power, low-cost, and secure technology that is widely used for creating PANs.

NEW QUESTION # 854
A technician is troubleshooting a computer that has a loud system fan and randomly freezes and reboots.
Which of the following is the most likely cause of these issues?

A. Incompatible hardware
B. Overheating processor
C. Defective power supply
D. Failing hard drive

Answer: B

Explanation:
Explanation
An overheating processor is the most likely cause of a computer that has a loud system fan and randomly freezes and reboots. A processor generates heat when it performs calculations, and if the heat is not dissipated properly, it can damage the processor or cause it to malfunction. A loud system fan indicates that the fan is working harder to cool down the processor, but it may not be enough to prevent overheating. A computer that freezes and reboots randomly is a common symptom of an overheating processor, as the system tries to protect itself from further damage by shutting down or restarting.
The other options are not as likely to cause these issues. A failing hard drive may cause data loss, corruption, or slow performance, but it does not affect the system fan or the processor temperature. A defective power supply may cause the computer to shut down unexpectedly, but it does not cause the system fan to be loud or the processor to overheat. Incompatible hardware may cause the computer to fail to boot, display errors, or crash, but it does not cause the system fan to be loud or the processor to overheat.
To troubleshoot and resolve an overheating processor issue, the technician should check and clean the air vents, provide proper ventilation, apply thermal paste, replace the fan or the heat sink, or upgrade the processor if necessary. The technician should also update the BIOS and the device drivers, adjust the power settings, and monitor the system temperature using diagnostic tools.

NEW QUESTION # 855
A technician is setting up a device to use two-factor authentication. Which of the following meets this requirement?

A. Password/thumbprint
B. Password/password
C. Password/PIN
D. Thumbprint/retinal scan

Answer: A

Explanation:
Explanation
Two-factor authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity. This means that in addition to providing something they know (such as a password or PIN), they must also provide something they have (such as a smart card or token) or something they are (such as a fingerprint or retinal scan).
In this case, the correct answer would be . This option meets the requirement for two-factor authentication because it combines two different types of authentication factors: something the user knows (the password) and something the user is (the thumbprint). The other options do not meet the requirement for 2FA because they either use only one type of authentication factor (A and D) or use two instances of the same type of factor (B).

NEW QUESTION # 856
While troubleshooting a user's smartphone issue, a technician notices that the display is visible but extremely hard to see. Which of the following is the most likely issue?

A. LCD glass
B. Inverter
C. IPS panel
D. Digitizer

Answer: B

Explanation:
An inverter failure commonly causes dim screens as it fails to power the backlight, which is crucial for visibility. The LCD glass, IPS panel, and digitizer relate to touch and image display, not brightness. According to CompTIA A+ Core 1 objectives, understanding mobile device display issues, including inverter-related problems, is essential for effective troubleshooting.

NEW QUESTION # 857
Which of the following is considered a connectionless protocol?

A. UDP
B. HTTPS
C. SSH
D. TCP

Answer: A

Explanation:
The correct answer is D. UDP.
UDP (User Datagram Protocol) is a connectionless protocol that does not establish a connection before sending or receiving data. UDP simply sends datagrams to the destination without checking if the receiver is ready or not. UDP does not guarantee reliable delivery, error correction, or in-order arrival of the data. UDP is faster and more efficient than connection-oriented protocols for applications that do not require reliability, such as streaming audio or video1 A) SSH (Secure Shell) is not a correct answer. SSH is a connection-oriented protocol that uses TCP (Transmission Control Protocol) as its transport layer. SSH establishes a secure and encrypted connection between two network endpoints before exchanging data. SSH provides authentication, confidentiality, and integrity for remote login and command execution2 B) TCP (Transmission Control Protocol) is not a correct answer. TCP is a connection-oriented protocol that establishes a connection before sending or receiving data. TCP ensures reliable delivery, error correction, and in-order arrival of the data. TCP is slower and more complex than connectionless protocols, but it provides more reliability and quality of service for applications that require it, such as web browsing or email1 C) HTTPS (Hypertext Transfer Protocol Secure) is not a correct answer. HTTPS is a connection-oriented protocol that uses TCP as its transport layer and SSL/TLS as its security layer. HTTPS establishes a secure and encrypted connection between a web browser and a web server before exchanging data. HTTPS provides authentication, confidentiality, and integrity for web transactions, such as online banking or shopping1
