CompTIA Updated 220-1201 Exam Questions and Answers by erick

The correct answer is B. Elasticity.

According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud Concepts:

Elasticity refers to the cloud computing capability to automatically allocate and deallocate resources based on current demand. This ensures that applications have the necessary compute, storage, and network capacity during peak loads, and resources can be scaled down when demand decreases, optimizing efficiency and cost.

Why the other options are incorrect:

A. Hybrid deployment: Refers to using a combination of public and private clouds; it does not describe dynamic resource allocation.

C. Multitenancy: Describes the architecture where multiple users share the same infrastructure securely.

D. Metered utilization: Refers to charging based on resource consumption; it is a billing mechanism, not a dynamic allocation feature.

correct answer is " Overclocking " and " Reduce CPU Clock speed " CPU is at 4.5 Ghz when normal is 3.2 Ghz. Overclocking too much can cause freezes, and this is a gaming computer sothe user probably took it too far. http://blog.logicalincrements.com/2018/12/4-troubleshooting-tips-overclocking-pc/

The correct answer is A. Loopback plug.

According to CompTIA A+ Core 1 220-1201 objectives under Networking:

A loopback plug is used to test a network interface card (NIC) port by sending a signal out of the port and back into the same port, verifying that the NIC can send and receive data properly.

This is a common diagnostic tool when troubleshooting network connectivity issues on individual devices.

Why the other options are incorrect:

B. Toner probe: Used for tracing and locating cables, not for testing NIC ports.

C. Cable tester: Checks the integrity of network cables but does not verify NIC send/receive functionality.

D. Network tap: Passively monitors network traffic but does not test the NIC port itself.

The correct answer is B. Inspect and replace the printer rollers.

According to CompTIA A+ Core 1 220-1201 objectives under Printers:

Frequent paper jams with no visible obstruction are often caused by worn or dirty feed rollers, which fail to grip and feed paper properly.

Inspecting and replacing the rollers ensures smooth paper feeding and prevents repeated jams, particularly in high-use network printers.

Why the other options are incorrect:

A. Check for firmware updates: Firmware updates address software or functionality issues, not mechanical paper feeding problems.

C. Reseat the fuser assembly: Fuser issues typically cause smudging or incomplete toner adhesion, not paper jams.

D. Clean the corona wire: The corona wire affects toner adhesion and print quality, not paper feeding.
