CompTIA 220-1202 PDF Dumps - Effective Tips To Pass

The CompTIA 220-1202 practice exam software of BraindumpQuiz has questions that have a striking resemblance to the queries of the CompTIA A+ Certification Exam: Core 2 (220-1202) real questions. It has a user-friendly interface. You don't require an active internet connection to run it once the 220-1202 Practice Test software is installed on Windows computers and laptops.

CompTIA A+ Certification Exam: Core 2 Sample Questions (Q297-Q302):

NEW QUESTION # 297
An end user ' s computer is unable to start. A technician examines the machine and does not hear any unusual noises but determines that no OS is found. Which of the following is most likely corrupt?

A. Trusted Platform Module
B. New Technology File System
C. Master boot record
D. Basic input/output system

Answer: C

Explanation:
"No OS found" commonly indicates the firmware can't locate boot instructions for the installed OS. If the drive isn't obviously failing (no unusual noises) and BIOS/UEFI settings are reasonable, a classic cause is a corrupt Master Boot Record (MBR) (on MBR-partitioned disks). Mike Meyers' Lab Manual explains that when BIOS can't find an OS, causes may include configuration issues or drive problems, but also states: "If the correct drive is already first in the boot sequence, the master boot record... may be corrupt and need to be rebuilt." The Lab Manual also explains what the MBR does: the first sector contains boot code that informs the system about installed operating systems, and "without this bit of code, your OS will never load." The All-in-One guide describes the same: BIOS looks at the first sector for instructions, and without the MBR code, the OS won't load.
NTFS corruption wouldn't typically present as "no OS found" at the firmware stage, and TPM issues usually create different security/boot errors. Therefore, MBR (D) is most likely.

NEW QUESTION # 298
A company wants to prevent unauthorized physical access to its mobile devices. Which of the following should the company do? (Choose two.)

A. Configure VPN software.
B. Enable screen timeout.
C. Turn on location services.
D. Disable built-in hotspots.
E. Install an antivirus application.
F. Use PIN authentication.

Answer: B,F

Explanation:
A PIN prevents unauthorized users from unlocking the device, and a screen timeout ensures the device locks automatically when unattended, protecting it from physical access.

NEW QUESTION # 299
A user's PC is performing slowly after the user clicked on a suspicious email attachment. The technician notices that a single process is taking 100% of RAM, CPU, and network resources.
Which of the following should the technician do first?

A. Reboot the computer
B. Educate the user about cybersecurity best practices
C. Run an antivirus scan
D. Disconnect the computer from the network

Answer: D

Explanation:
The technician should disconnect the computer from the network (Option A) first to prevent any further spread of the infection or data loss. Once the machine is isolated from the network, the technician can safely investigate the malware without risking infection to other systems.

NEW QUESTION # 300
A user hears an unexpected noise coming from their desktop computer. To troubleshoot the issue, a technician needs to open the case. Which of the following actions should the technician take next?

A. Ground the system
B. Disconnect the power
C. Open the system cover
D. Remove any peripheral devices

Answer: B

Explanation:
The correct answer is C. Disconnect the power, because safety is the first priority when working inside a computer case. Before opening the system, all power sources must be removed to prevent electrical shock and hardware damage.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, technicians should always shut down the system and disconnect the power cable before opening a computer. Even powered-off systems can still carry electrical current if they remain plugged in.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that unexpected noises are often caused by fans, loose cables, or failing hard drives. Opening the case while the system is powered can cause injury or damage sensitive components.
The Mike Meyers / Mark Soper Lab Manual reinforces the standard safety sequence: power off the system, unplug it, discharge residual power, and then apply grounding measures before touching internal components.
Because disconnecting power eliminates electrical hazards and protects both the technician and the equipment, C is the correct answer.

NEW QUESTION # 301
Welcome to your first day as a Fictional Company, LLC helpdesk employee. Please work the tickets in your helpdesk ticket queue.
INSTRUCTIONS
Click on individual tickets to see the ticket details, and view applicable attachments to determine the problem.
Select the appropriate issue from the ' Issue ' drop-down menu. Then, select the most efficient resolution from the ' Resolution ' drop-down menu. Finally, select the proper command or verification to remediate or confirm your fix of the issue from the
' Verify/Resolve ' drop-down menu.

Answer:

Explanation:

Explanation:
Ticket #8675310
* Issue: Limited network connectivity
* Resolution: Refresh DHCP
* Verify/Resolve: ipconfig /renew
For the Low priority ticket #8675310 (" A small yellow triangle appeared in the taskbar. I am no longer able to access network resources. "), the Windows yellow triangle on the network icon is the classic indicator of limited connectivity (often caused by a bad/expired DHCP lease, APIPA address, missing default gateway, or DNS info not being assigned).
Correct PBQ Selections (Ticket #8675310)
Issue
Limited network connectivity
Why (CompTIA logic):
That yellow warning triangle means the NIC is connected at Layer 2 (link is up), but the system likely doesn't have valid Layer 3 config (IP/gateway/DNS), so it can't reach network resources.
Resolution
Refresh DHCP
Why this is the most efficient fix:
When a Windows PC can't access network resources and shows "limited connectivity," the fastest, lowest- risk fix is to renew DHCP so the PC can pull:
* a valid IP address
* default gateway
* DNS servers
This directly resolves the most common root cause behind that icon.
Verify / Resolve
ipconfig /renew
Why this is the correct verification/remediation command:
ipconfig /renew is the direct command to request a fresh DHCP lease . After renewal, the user should regain access to network resources if DHCP was the issue.
What this fixes (what you'd expect to see)
Before the fix, the attachment ( Output.txt ) in these PBQs typically shows symptoms like:
* 169.254.x.x (APIPA) # DHCP failed
* Missing/blank Default Gateway
* DNS not present or incorrect
After ipconfig /renew, you should see a normal private IP (like 192.168.x.x / 10.x.x.x / 172.16-31.x.x ) and a valid gateway/DNS.
