B. Change the paper type

* Check the toner level and replace the toner cartridge if it is low or empty1.
* Remove the toner cartridge and inspect the drum unit for any signs of damage, such as scratches, cracks, or toner buildup. Clean the drum unit with a soft cloth or replace it if it is damaged23.

NEW QUESTION # 262
A server administrator is building a new application server. Which of the following, RAID levels provides MAXIMUM performance and redundancy?
A. RAID 5
B. RAID 0
C. RAID 1
D. RAID 10
Answer: D
Explanation:
Explanation
RAID 10 is a combination of RAID 1 and RAID 0, which provides both performance and redundancy. RAID
1 mirrors data across two or more disks, while RAID 0 stripes data across two or more disks. RAID 10 combines these two methods to create a mirrored stripe set, which can tolerate multiple disk failures as long as they are not in the same mirror. RAID 10 requires at least four disks and offers better performance than RAID
5, which uses parity to provide redundancy. References: https://www.comptia.org/blog/what-is-raid-0-1-5-6-10
NEW QUESTION # 263
A colleague has a laptop that has been working as expected for several years wall outlet. The MOST likely component that needs to be replaced is the:
A. battery.
B. system fan.
C. hard drive.
D. power adapter.
Answer: A
Explanation:
Explanation
Based on the information provided in the question, the MOST likely component that needs to be replaced is A.
power adapter. If a laptop has been working as expected for several years but suddenly stops working when it is plugged into a wall outlet, it is possible that the power adapter has failed and is no longer able to provide power to the laptop. In this case, replacing the power adapter would likely resolve the issue.
The other components listed in the options (battery, system fan, and hard drive) could also potentially fail and cause issues with a laptop's performance. However, based on the specific scenario described in the question (the laptop suddenly stops working when plugged into a wall outlet), it seems most likely that the issue is related to the power adapter.
If the laptop has been working as expected for several years and suddenly stops working, the power adapter is the most likely component that needs to be replaced. Over time, the power adapter can become worn or damaged, resulting in a loss of power to the laptop. References: CompTIA A+ Certification Exam Guide, Ninth Edition, Chapter 3
NEW QUESTION # 264
To control costs a company provides a limited number or users with company phones One of these users opens a support ticket because the phone no longer allows internet Drowsing over a cellular connection The user acknowledges that the phone worked before the user's child streamed several movies using the device Which of the following describes why the phone cannot browse the Internet?
A. The device's plan has been unpaid
B. The company's group policy disabled the device
C. The child accidentally connected to a neighbor's WLAN
D. The device has a data cap and has reached that limit
Answer: D
Explanation:
It is common for companies to place a data cap on the devices they provide to their employees, to control costs. If a user has exceeded the data cap, the phone may no longer allow internet browsing over a cellular connection. This is usually because the cellular data usage has exceeded the allotted amount for the particular plan the device is on, and the service provider has temporarily suspended the data connection.
It is unlikely that the child accidentally connected to a neighbor's WLAN because this would not affect the cellular data connection. Similarly, it is unlikely that the company's group policy has disabled the device, as this would likely affect all devices under the same policy. If the device's plan has been unpaid, the service provider would likely temporarily suspend all services, not just the cellular data connection.
