220-1202 CompTIA A+ Core 2 2025 Exam Free Practice Exam Questions (2026 Updated)

The correct answer is A. Detailed guides for resolving common issues, because effective deployment documentation must support ongoing troubleshooting and support, not just initial installation. Including known issues and resolution steps allows future technicians to resolve problems efficiently and consistently.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, high-quality technical documentation should include error conditions, common failure points, and step-by-step remediation procedures. This information significantly reduces mean time to resolution (MTTR) and improves service quality.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that help desk documentation should evolve over time, incorporating lessons learned from previous incidents. Troubleshooting guides turn deployment documentation into a practical reference rather than a static record.

The Mike Meyers / Mark Soper Lab Manual further clarifies that email logs are informal and unstructured, vendor contact information is supplementary, and end-user manuals are not intended for technical troubleshooting. None of these provide actionable guidance for technicians resolving future issues.

Because the goal is to ensure long-term supportability and effective troubleshooting, the most important inclusion is detailed guides for resolving common issues, making A the correct answer.

Comprehensive and Detailed Explanation From Exact Extract:

In a domain environment, printers are typically deployed via a print server. Users can browse available printers on the server and install them directly.

All-in-One Exam Guidementions:

“In a corporate domain, printers are managed via a centralized print server. Users can select the desired printer from the server’s shared list.”

Comprehensive and Detailed Explanation From Exact Extract:

Memory usage is critically high, suggesting many applications or background processes. Closing unnecessary programs will immediately free up RAM.

FromTravis Everett – All-in-One Exam Guide:

“High memory usage with moderate CPU load usually means too many applications are open. Close unnecessary apps or use Task Manager to end processes.”

Comprehensive and Detailed Explanation From Exact Extract:

An "OS Not Found" error typically indicates that the computer is attempting to boot from a drive that doesn't contain a valid operating system or bootable partition. The presence of a USB drive might be confusing the boot order. Therefore, the first step a technician should take is to verify and adjust the boot sequence in the system’s firmware (BIOS or UEFI). It's possible that the USB drive is being prioritized over the internal hard drive, which may cause the system to miss the OS entirely.

A. Running data recovery tools is premature before confirming boot order.

B. Repartitioning the disk would destroy existing data—this should not be done until confirmed the OS is actually missing.

D. Switching between UEFI and BIOS (legacy mode) might help in rare cases, but it is not the first step in standard OS boot issue troubleshooting.

Issue: Limited network connectivity

Resolution: Refresh DHCP

Verify/Resolve: ipconfig

Issue (drop-down)

Limited network connectivity

Why this matches:

“Internet Down” most commonly indicates the workstation has lost valid Layer 3 connectivity (bad/expired DHCP lease, APIPA address, wrong gateway, etc.). In CompTIA A+ terms, this aligns best with limited connectivity symptoms (can’t reach internet resources).

Resolution (drop-down)

Refresh DHCP

Why this is the most efficient fix:

If the client has:

an expired lease

an APIPA address (169.254.x.x) because DHCP failed

an incorrect IP/gateway from a bad lease

…then the fastest first remediation is to renew DHCP to obtain a correct IP address, default gateway, and DNS servers. This is a standard CompTIA A+ troubleshooting action (quick, low-risk, high-success).

Verify/Resolve (drop-down)

ipconfig

Why this is the correct verification tool:

ipconfig is the primary Windows CLI tool to:

check current IP settings (ipconfig /all)

release/renew DHCP (ipconfig /release and ipconfig /renew)

confirm you received a valid IP + gateway + DNS, which is required for internet access.

What you would do (mapped to those choices)

Using ipconfig to complete “Refresh DHCP” and confirm the fix:

Check current addressing

ipconfig /all

Look for:

Valid IPv4 (not 169.254.x.x)

Valid Default Gateway

DNS servers present

Refresh the DHCP lease

ipconfig /release

ipconfig /renew

Verify outcome

Run ipconfig again to confirm:

You now have a correct IP for the network

Default gateway is populated

If the gateway/DNS populate correctly, internet access typically returns.

First Chat Response:When the user mentions setting up a new router, the best initial response to maintain a helpful and professional tone is:

>Select reply:"I am happy to assist you today."

Second Chat Response:When the user states that they need to set up basic security settings:

>Select reply:"Is this the first router in your office?"

Third Chat Response:After learning it's a replacement router and the user is logged into the router's web page:

>Select reply:"The first thing you need to do is change the default password."

Fourth Chat Response:For the response about password settings:

>Select reply:"Create a new password with an uppercase, a lowercase, and a special character."

Fifth Chat Response:When the router prompts to reboot:

>Select reply:"Yes, reboot please."

Study Guide Reference: The CompTIA A+ Core 2 guide highlights the importance of changing default credentials and using strong password policies, particularly in SOHO environments where routers are often targeted.

1st CLI Resolution

copy "C:\Program Files\Testing\msvcp100.dll" "User-PC02\C$\Windows\System32" /v /y

2nd CLI Resolution

regsvr32 msvcp100.dll

Why These Are the Correct Choices (Exam Logic)

Why the COPY command is first

The error explicitly states MSVCP100.dll is missing

Other users can run the app → the DLL exists on another system

The fastest, least disruptive fix (preferred by CompTIA) is to:

Copy the known-good DLL into C:\Windows\System32

The /v switch verifies the copy, and /y suppresses prompts — both are enterprise-safe defaults

This restores the missing runtime dependency immediately.

Why REGSVR32 is second

After copying a DLL, Windows may not recognize or properly load it

regsvr32 registers the DLL with the operating system

This ensures:

The Testing application can properly call the runtime library

The fix persists after reboot

The completed configuration:

1. Wireless AP (LAN side)

1. LAN IP: 192.168.10.1

2. Encryption: WPA2 PSK

2. Router (port-forward rule)

1. Allow TCP Any 3389

This forwards inbound RDP traffic (TCP/3389) from the Internet to the Windows PC, enabling Remote Desktop access.

3. Firewall (screened subnet side)

1. LAN IP: 10.100.0.1

4. Device placement

1. PC: place behind the router (where the port-forward rule points).

2. Game console: place on the Wireless AP (so it can use chat and extra services over WPA2 PSK).

3. Firewall: place in front of the screened subnet (with its 10.100.0.1 IP facing that subnet).

The Windows PC is placed in the screened subnet (behind the firewall) for enhanced security. Remote access to this PC requires port forwarding of TCP port 3389 (RDP), which is correctly configured through the router.

The Game Console is placed on the Wireless AP LAN, using WPA2 PSK for a secure wireless connection. Game consoles typically use peer-to-peer chat and online services that require open access without firewall restrictions, which is why the console is not placed behind the firewall.

CompTIA A+ 220-1102 Reference Points:

Objective 3.4: Given a scenario, implement best practices associated with data and device security.

Objective 2.4: Given a scenario, use appropriate tools to support and configure network settings.

Study Guide Reference: CompTIA A+ Core 2 guides recommend using screened subnets (a type of DMZ) for systems needing controlled external access, such as remote desktops, while placing gaming and media devices on less restricted networks for full functionality.

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.
