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

Comprehensive and Detailed Explanation From Exact Extract:

Older tablets may not support newer app versions due toincompatible or unsupported operating systems. App developers often drop support for outdated OS versions.

FromTravis Everett – CompTIA A+ All-in-One Exam Guide:

“When an app won't install on an older device, check the OS version. Most apps require a minimum OS level for compatibility and security.”

Comprehensive and Detailed Explanation From Exact Extract:

A low-level format (also referred to as a zero-fill or full format) writes over every sector on a storage device, effectively destroying the existing data and making recovery nearly impossible. Unlike degaussing, which renders the drive unusable, a low-level format maintains the integrity of the device, allowing it to be repurposed or reused.

A. Deleting partitions does not fully erase data; it only removes references in the partition table.

B. EFS (Encrypting File System) encrypts files but does not securely wipe them.

D. Degaussing destroys the magnetic structure of a drive, making it inoperable and not reusable.

Most public Wi-Fi networks requireinteraction with a captive portal(e.g., terms of use or login). Dismissing it prevents the user from gaining internet access. Reconnecting and completing the portal page is essential.

FromAll-in-One Exam Guide:

“Many public hotspots require user acknowledgment or login via a captive portal. Skipping this step results in no internet access.”

The scenario involves an application that should retrieve data from a local database server but is failing to do so. This likely indicates a problem in communication between the application and the database server (such as a network issue, port misconfiguration, or service unavailability). The correct troubleshooting approach involves testing the network/service connectivity between the client and the database.

Let’s examine the options:

A. ipconfig:This command displays IP configuration details for Windows systems, such as IP address, subnet mask, and default gateway. While useful for diagnosing general network issues, it does not test service connectivity or the availability of a specific application port/service.

B. nslookup:Used to query DNS servers to resolve domain names to IP addresses. However, since the question references a local server (likely accessed via IP or static hostname), DNS is probably not involved. Also, it does not test application/service availability.

C. netstat:Displays active TCP connections, listening ports, and routing tables. It helps determine whether the local system is listening for or maintaining any network connections, but it does not initiate a connection to test availability. It’s diagnostic but not interactive for service testing.

D. curl:This is the most appropriate tool for this scenario. curl is used to test connectivity to services over protocols like HTTP, HTTPS, FTP, and more. If the application retrieves data via a web interface or API (common in database-driven applications), curl can be used to test if the application can successfully reach and retrieve data from the server. It provides immediate, testable feedback on whether the server and service are available and responsive.

Example usage:

curlhttp://localhost:8080/api/data

This command would test whether a local server's application programming interface (API) is available and responding on port 8080.

CompTIA A+ 220-1102 Reference Points:

Objective 2.4: Given a scenario, use appropriate tools to troubleshoot and support Windows OS issues.

Objective 3.3: Use appropriate tools to troubleshoot and resolve issues.

The CompTIA A+ Core 2 study guide references curl as a useful command-line utility for testing connectivity and troubleshooting application access to services.

Once the system is cleaned, the next priority is toeducate the useron safe practices to prevent recurrence.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Post-malware remediation should include user education to prevent reinfection and identify how the malware was introduced.”

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.”

Comprehensive and Detailed Explanation From Exact Extract:

If unauthorized or non-standard applications are appearing on systems and users are receiving licensing prompts, it’s likely users are installing software themselves. Removing users from the local administrators group will prevent them from installing software without approval and reduce the likelihood of introducing unapproved or malicious programs.

A. Deploying a PKI helps with secure communications but doesn’t address user software installation rights.

C. Blocking suspicious websites is helpful but doesn’t prevent local installations.

D. Stricter UAC may add prompts but can still be bypassed by admin users.

Comprehensive and Detailed Explanation From Exact Extract:

BitLocker To Go is a Microsoft encryption feature specifically designed for removable drives such as USB flash drives and external hard drives. It allows users to protect the data on these devices by requiring a password to decrypt the contents, thereby preventing unauthorized access in the event the device is lost or stolen.

A is correct because BitLocker To Go is directly tied to password-protecting removable media.

B and C are unrelated to BitLocker To Go; Secure Boot and VPN encryption are entirely different security layers.

D applies to BitLocker (not BitLocker To Go) and full disk encryption on internal drives using TPM.

In emotionally sensitive situations, it is critical that the technicianprojects confidenceand maintains a calm, positive demeanor to reassure the customer.

FromAll-in-One Exam Guide:

“Confidence and empathy are key when working with distressed users. Demonstrating competence can help ease the customer's anxiety.”

Comprehensive and Detailed Explanation From Exact Extract:

When an OS reaches its end of life (EOL), it no longer receives updates or support, including critical security patches.

From the Quentin Docter Study Guide:

“End-of-life means the manufacturer no longer supports the OS with updates or security patches, which exposes systems to vulnerabilities unless upgraded”.

All-in-One Exam Guide adds:

“End-of-life notifications serve as a final warning that continued use of the OS will be insecure and unsupported. It’s crucial for administrators to plan migration”.
