220-1202 Exam Dumps - CompTIA A+ Questions and Answers

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.

The Local Users and Groups Manager (lusrmgr.msc) is the utility for managing user accounts, including renaming the default Administrator.

From Quentin Docter – Complete Study Guide:

“The lusrmgr.msc snap-in allows renaming and managing local user accounts, including the default administrator.” .

The correct answer is C. Listen to the customer’s concerns and acknowledge their frustrations, because effective communication and empathy are critical components of professional help desk interactions—especially when customers are upset.

According to the Quentin Docter – CompTIA A+ Complete Study Guide, technicians should always demonstrate active listening, empathy, and professionalism. Acknowledging a user’s frustration helps de-escalate tense situations and builds trust.

The Travis Everett & Andrew Hutz – All-in-One Exam Guide emphasizes that users who feel unheard are less cooperative and more dissatisfied. Before troubleshooting or escalation, technicians should validate the customer’s experience and reassure them that the issue will be addressed.

The Mike Meyers / Mark Soper Lab Manual reinforces that blaming previous technicians or immediately escalating without communication can worsen the situation. Asking technical questions too early may come across as dismissive.

Because the goal is to communicate professionally and effectively, the technician should first listen and acknowledge the user’s frustration, making C the correct answer.

End-user education is crucial after malware removal to prevent recurrence. Teaching safe browsing habits and security awareness completes the remediation cycle.

Mark Soper – Mike Meyers' Lab Manualstates:

“Educating the user after malware remediation is part of the CompTIA malware response methodology. This includes training on phishing and safe practices.”

Comprehensive and Detailed Explanation From Exact Extract:

To work remotely without physically transporting a workstation, the user needs:

C. RDP (Remote Desktop Protocol): Allows graphical remote access to a Windows PC at the office.

D. VPN (Virtual Private Network): Establishes a secure tunnel to access the corporate network remotely, making the internal PC reachable.

A. SPICE is used in virtual machine environments and is not typically used for end-user remote desktop access.

B. SSH is a text-based remote access tool used mostly for Linux systems.

E. RMM (Remote Monitoring and Management) is used by IT administrators for support — not end-user remote access.

F. WinRM is used for Windows remote management via PowerShell, not for full desktop access.

Comprehensive and Detailed Explanation From Exact Extract:

The user’s issue likely stems from amobile data restriction or cap, especially since uploads work on Wi-Fi but not cellular. Checkingdata usage limitswill help determine if mobile uploads are blocked.

FromAll-in-One Exam Guide:

“When data-intensive functions fail on mobile networks but not on Wi-Fi, it’s often due to data caps or metered connection limits.”

Comprehensive and Detailed Explanation From Exact Extract:

This scenario describes a rogue access point — a malicious or unauthorized wireless access point that uses the same SSID as the legitimate network. Users may connect to it unknowingly, which can result in limited network access, data interception, or redirection of traffic. The inability to reach internal file servers supports this being an unauthorized AP with no connection to internal resources.

A. A DNS issue would impact name resolution, not connectivity to file servers directly.

B. VLAN issues generally affect segmentation, not mimic SSID problems.

C. An incorrect IP address could cause connectivity issues, but not in the presence of a malicious AP broadcasting the same SSID.

Comprehensive and Detailed Explanation From Exact Extract:

Group Policyis the standard administrative tool for enforcing security and configuration settings across domain-joined systems, including disabling guest accounts.

FromQuentin Docter – CompTIA A+ Study Guide:

“Disabling guest accounts and applying consistent security policies across multiple machines is best achieved through Group Policy on a Windows domain.”

Comprehensive and Detailed Explanation From Exact Extract:

Before any change is implemented, it must bedocumentedas part of change management procedures. This ensures transparency, review, and tracking.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Documenting a change is the first step in change management. This includes defining the scope, purpose, impact, and implementation plan before approval or scheduling.”

Comprehensive and Detailed Explanation From Exact Extract:

Windows Helloallows biometric and PIN-based login, which are easier and more user-friendly than passwords.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Windows Hello supports biometric authentication and PINs, providing easier and secure access especially for users who have trouble remembering passwords.”
