CompTIA A+ Certification Exam: Core 1 Sample Questions (Q229-Q234):

NEW QUESTION # 229
A user needs a technician's help connecting a laptop to a projector The projector is old and only has analog input. Which of the following cable types should the technician use to connect the laptop to the proJector?

A. HDMI
B. DisplayPort
C. VGA
D. RS-232

Answer: C

Explanation:
VGA stands for Video Graphics Array, and it is a type of cable that can be used to transmit analog video signals between devices, such as laptops, monitors, or projectors. VGA cables have 15 pins arranged in three rows, and they are usually color-coded blue. VGA cables can support resolutions up to 2048 x 1536 pixels, but they have low quality and limited color depth compared to modern digital standards such as HDMI or DisplayPort .
A projector is a device that projects an image or a video onto a large surface, such as a wall or a screen. A projector can have different types of input ports, such as VGA, HDMI, DVI, or USB. A projector can also have different types of output technologies, such as LCD, DLP, or LED .
In this scenario, the user needs a technician's help connecting a laptop to a projector. The projector is old and only has analog input. This means that the projector can only accept analog video signals, and not digital ones.
Therefore, the technician should use a VGA cable to connect the laptop to the projector, as it is the most common type of analog video cable. The technician should also make sure that the laptop and the projector have compatible VGA ports, and that the laptop's display settings are adjusted to match the projector's resolution and aspect ratio.

NEW QUESTION # 230
Which of the following cables should be used to terminate ST connectors on each end?

A. Coaxial
B. Shielded twisted pair
C. HDMI
D. Optical fiber

Answer: D

Explanation:
Optical fiber is the type of cable that should be used to terminate ST connectors on each end. ST connectors are commonly used for fiber optic cables, which transmit data using light pulses.
Coaxial, shielded twisted pair, and HDMI are not types of cables that use ST connectors, but different types of connectors and transmission methods.

NEW QUESTION # 231
A video game developer is requesting a new desktop computer with eight sticks of memory. The developer wants the desktop computer to take advantage of all available memory bandwidth without sacrificing performance. Which of the following would be the BEST solution?

A. Quad-channel with DDR5 SODIMM
B. Quad-channel with DDR4 RAM
C. Dual-channel with DDR4 RAM
D. Triple-channel with DDR5 ECC RAM

Answer: B

Explanation:
Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops. ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel. References: https://www.comptia.org/certifications/a#examdetails

NEW QUESTION # 232
A user requested upgrades to a company-Issued laptop to increase its performance while working with a large database stored on drive C. Which of the following tasks should a systems administrator complete to BEST meet this goal? (Choose two.)

A. Install a hybrid drive.
B. Increase the RAM.
C. Upgrade to 1GB NIC.
D. Upgrade the power supply.
E. Migrate to a SSD.
F. Configure RAID 1.

Answer: B,E

Explanation:
To increase the performance of a laptop working with a large database stored on drive C, a systems administrator should increase the RAM and migrate to an SSD. Increasing the RAM will help the laptop to better handle the large database, while migrating to an SSD will improve the speed at which the laptop can access the database. Configuring RAID 1, installing a hybrid drive, upgrading to a 1GB NIC, and upgrading the power supply will not directly improve the laptop's performance when working with a large database.

NEW QUESTION # 233
A user with a self-configured, static IP address cannot connect to the internet. The technician runs an ipconfig command and receives the following output:

Which of the following should the technician edit?

A. IPv4 address
B. Default gateway
C. DHCP server
D. Subnet mask

Answer: B

Explanation:
Explanation
The correct answer is D. Default gateway.
A default gateway is the device that connects a local network to other networks, such as the internet. A default gateway is usually a router or a modem that has an IP address on the same subnet as the local network. A default gateway is necessary for a device to communicate with devices outside its local network.
In this case, the user has a self-configured, static IP address of 192.168.1.20, which belongs to the subnet
192.168.1.0/24 (with a subnet mask of 255.255.255.0). However, the default gateway is set to 192.168.0.1, which belongs to a different subnet (192.168.0.0/24). This means that the user's device cannot reach the default gateway, and therefore cannot connect to the internet.
The technician should edit the default gateway to match the correct subnet of the user's device, such as
192.168.1.1 or 192.168.1.254, depending on the configuration of the network.
