Explanation:

The correct answer is C. OLED.
OLED stands for Organic Light-Emitting Diode, and it is a type of display technology that uses organic compounds to create light and color. Unlike LCD (Liquid Crystal Display) or Plasma displays, OLED does not require a backlight or a filter to produce images. This means that OLED can offer higher contrast, wider color gamut, and better viewing angles than other display types.
LCD displays use liquid crystals that are sandwiched between two polarizing filters and illuminated by a backlight. The liquid crystals can change their orientation and block or allow light to pass through the filters.
LCD displays can have different panel types, such as IPS (In-Plane Switching), VA (Vertical Alignment), or TN (Twisted Nematic), which affect the color accuracy, response time, and viewing angles of the display.
Plasma displays use gas-filled cells that are electrically charged to create plasma, which emits ultraviolet light.
The ultraviolet light then excites phosphors that emit visible light and color. Plasma displays can produce deep blacks and high contrast, but they are also prone to image retention, screen burn-in, and high power consumption.
VGA stands for Video Graphics Array, and it is not a display type but a video interface standard that was introduced in 1987. VGA can transmit analog signals from a computer to a monitor, but it has low resolution and limited color depth compared to modern digital standards such as HDMI or DisplayPort.
Therefore, OLED is the best display type for graphic designers who want the most accurate color spectrum and the widest viewing angles. OLED displays can also be thinner and lighter than LCD or Plasma displays, which makes them ideal for laptops. However, OLED displays are also more expensive and less durable than other display types, and they may suffer from image retention or burn-in over time.
NEW QUESTION # 169
An employee cannot connect to the wireless network at the office but can connect to a personal wireless network when at home. The technician verifies the wireless network name is correct, and the signal strength appears to be strong. Which of the following is the best action for the technician to take to resolve the issue?
Answer: D
Explanation:
802.1X is a network authentication protocol commonly used in enterprise environments. If the user cannot connect to the office wireless network but can connect at home, the issue is likely related to the 802.1X certificate required for authentication. Installing or updating the certificate will resolve the issue.
Why Not B (Check the wireless router settings): If other users can connect to the network, this step is unnecessary.
Why Not C (Update the wireless driver): Driver updates might resolve connectivity issues but are unrelated to
802.1X certificate authentication.
Why Not D (Disable the Windows firewall): The firewall does not affect 802.1X authentication.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.6, wireless network authentication.
NEW QUESTION # 170
A technician is attempting to log in to a local company portal. When the technician types the URL into the address bar, the browser is unable to resolve and display the web page. The technician tries at another workstation, and the result is the same. Other web pages are not having any issues. Which of the following should the technician check first?
Answer: A
Explanation:
The technician is unable to access the company portal website, but other websites work fine. This suggests an issue with resolving the specific URL of the company portal, which is a function of DNS.
Here's why other options are not the most likely cause:
DHCP reservations: This is not relevant as the issue persists even when the technician tries a different workstation, indicating a problem beyond individual device configuration.
Static IP addresses: Similar to DHCP reservations, static IPs are not likely the cause as both affected workstations are experiencing the issue.
Default gateway: While the default gateway is necessary for internet access, other websites are working, making it less likely to be the root cause.

NEW QUESTION # 171
A computer technician is investigating issues with a user's workstation. The user reports the following:
*Loading the operating system takes much longer than usual
*Clicking sounds are coming from inside the workstation
Which of the following is the most likely cause of the issue?
Answer: B
Explanation:
The symptoms described, such as the operating system taking longer than usual to load and hearing clicking sounds from within the workstation, are indicative of a failing hard drive. Clicking sounds, often referred to as the "click of death," signal the read/write head of the hard drive struggling to function properly. This mechanical failure leads to longer load times as the system struggles to read data from the disk. It is crucial to back up data and consider replacing the hard drive to prevent data loss.
