NEW QUESTION # 15
A user has been adding data to the same spreadsheet for several years. After adding a significant amount of data, they are now unable to open the file. Which of the following should a technician do to resolve the issue?

A. Revert the spreadsheet to the last restore point.
B. Upgrade the network connection speed.
C. Increase the amount of RAM.
D. Defragment the storage drive.

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When a spreadsheet becomes very large, opening and processing it requires more memory (RAM). If the system doesn't have sufficient memory, it may fail to load the file properly. Upgrading or increasing the available RAM can resolve performance and loading issues with very large files.
A: Restore points roll back system settings, not individual file content.
C: Defragmentation optimizes disk performance but won't help with memory issues.
D: Network speed has no effect if the file is stored and opened locally.
Reference:
CompTIA A+ 220-1102 Objective 3.3: Troubleshoot common application and performance issues.
Study Guide Section: Troubleshooting large-file performance and system resource limitations

NEW QUESTION # 16
A user recently installed an application that accesses a database from a local server. When launching the application, it does not populate any information. Which of the following command-line tools is the best to troubleshoot the issue?

A. netstat
B. ipconfig
C. nslookup
D. curl

Answer: D

Explanation:
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 networkissues, 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.

NEW QUESTION # 17
A technician is setting up a surveillance system for a customer. The customer wants access to the system's web interface on the LAN via the system's IP address. Which of the following should the technician use to prevent external log-in attempts from the internet?

A. Subnetting
B. Content filtering
C. Port mapping
D. Static IP

Answer: C

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To prevent external access, the technician should avoid exposing the surveillance system's port to the public internet. Port mapping (also known as port forwarding) is the method used to control which internal devices and ports are accessible from the outside. By not configuring port forwarding for the device, external login attempts are effectively blocked.
B: Subnetting organizes IP addresses but doesn't directly restrict access.
C: A static IP ensures consistent addressing but does not secure access.
D: Content filtering is used to restrict web content, not to block access to a web interface.
Reference:
CompTIA A+ 220-1102 Objective 2.2: Compare and contrast security measures and tools.
Study Guide Section: SOHO router security - port forwarding and blocking external access

NEW QUESTION # 18
A small office reported a phishing attack that resulted in a malware infection. A technician is investigating the incident and has verified the following:
# All endpoints are updated and have the newest EDR signatures.
# Logs confirm that the malware was quarantined by EDR on one system.
# The potentially infected machine was reimaged.
Which of the following actions should the technician take next?

A. Discuss the cause of the issue and educate the end user about security hygiene
B. Suggest alternate preventative controls that would include more advanced security software
C. Flash the firmware of the router to ensure the integrity of network traffic
D. Install network security tools to prevent downloading infected files from the internet

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
After containment and remediation, one of the final steps in incident response is user education. Since the root cause was a phishing attack, it is essential to educate users about identifying phishing attempts, safe browsing practices, and how to handle suspicious communications. This improves overall security posture and helps prevent future incidents.
A: Installing additional tools may be helpful but is a long-term step.
C: Flashing router firmware is not warranted unless the network hardware is known to be compromised.
D: Suggesting more advanced tools might be excessive given that the EDR successfully contained the incident.
