CompTIA Updated 220-1202 Exam Questions and Answers by rayyan

Comprehensive and Detailed Explanation From Exact Extract:

Remote wipe is the best option to prevent unauthorized access to data when a mobile device is lost or stolen—especially if the user is unaware of the loss. It allows administrators or mobile device management (MDM) systems to remotely erase all data on the device, rendering it unusable for unauthorized users.

A. Encryption protects the data, but if the device remains powered and logged in, it may still be accessible.

C. Geofencing can restrict features based on location but does not erase data.

D. Facial recognition helps secure access but can be bypassed in some cases or fail in practical situations.

Comprehensive and Detailed Explanation From Exact Extract:

Windows 11 features a“Do Not Disturb”mode under Notification settings, which is designed to suppress interruptions during tasks like videoconferencing.

FromQuentin Docter – CompTIA A+ Complete Study Guide:

“Windows 11 introduces Do Not Disturb and Focus Assist under notification settings, enabling users to mute alerts during presentations or calls.”

Comprehensive and Detailed Explanation From Exact Extract:

An evil twin is a rogue wireless access point set up to mimic a legitimate Wi-Fi network. Unsuspecting users may connect to it, giving attackers the opportunity to intercept traffic, steal credentials, or install malware. The evil twin often uses the same SSID as the real network to fool users.

A. Stalkerware is spyware installed to track user activity, typically on personal devices.

C. Tailgating is a physical security breach involving unauthorized entry behind someone with access.

D. Shoulder surfing involves observing a person entering confidential data, such as PINs or passwords.

Comprehensive and Detailed Explanation From Exact Extract:

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.
