Troubleshooting Printers and Cloud Computing

Front

A technician is troubleshooting an all-in-one laser printer that prints a vertical line when making copies and scans. The issue only occurs during copying and scanning, not printing or faxing.

Back

The document feeder is the likely cause of the problem. The scanner assembly, specifically the glass used by the automatic document feeder (ADF), may be dirty, scratched, or have residue on it, causing vertical lines on scanned or copied documents.

An advantage of using a hybrid cloud instead of a public cloud.

Back

A hybrid cloud allows organizations to meet data residency requirements, providing flexibility to store sensitive data in private environments while leveraging public cloud resources for other tasks.

Front

The primary advantage of a hybrid cloud in meeting data residency requirements.

Back

A hybrid cloud allows organizations to keep sensitive or regulated data on-premises or in a private cloud while using the public cloud for less sensitive workloads. This is especially important for compliance with laws or regulations requiring data to remain in specific geographic locations or under direct organizational control.

Front

A public cloud alone may not guarantee data residency compliance.

Back

A public cloud alone may not guarantee where data is physically stored, whereas a hybrid cloud provides flexibility to control data placement while benefiting from cloud scalability.

Actions a technician can take to resolve a desktop PC losing system date/time after every power outage.

Back

1. Repair the backup power source. 2. Replace the CMOS battery.

Front

Role of the CMOS battery in a computer system

Back

The CMOS battery is responsible for maintaining the system clock and BIOS configuration. A failing battery can cause the date and time to reset after power loss.

Front

Action to take if the system date and time are lost after every power outage

Back

Repair the backup power source and replace the CMOS battery, as the motherboard is not receiving power to retain BIOS settings when the system is off.

Front

Impact of disabling NTP on time accuracy issues in a computer system

Back

Disabling NTP worsens time accuracy rather than fixing it, as NTP is used to synchronize the system clock with an accurate time source.

Front

Network configuration concept that ensures a printer is assigned a specific IP address even if all addresses are depleted

Back

Reservation ensures that a printer will still be assigned a specific IP address even if all addresses are depleted.

Front

A DHCP reservation ensures that a specific device always receives the same IP address based on its MAC address, even if the DHCP address pool is fully depleted.

Back

This guarantees consistent network addressing for devices that must remain reachable at a fixed IP, like printers or servers, without requiring manual static IP configuration.
