Comprehensive and Detailed Explanation From Exact Extract:
If a system becomes unresponsive while opening a specific spreadsheet, the issue is likely tied to the file's size or the complexity of its content (e.g., embedded formulas, macros, or graphics). High memory utilization caused by the file can lead to temporary freezing or application "Not Responding" messages. Checking the spreadsheet's file size and monitoring system memory in Task Manager will help isolate performance bottlenecks.
A: Anti-malware logs are important for security troubleshooting but less likely relevant to spreadsheet-related performance issues.
B: Workstation repair is for system-wide problems and not necessary for a single-file issue.
C: Bandwidth relates to network usage and wouldn't impact opening a local file.

The correct answer is B. SSID configuration, because controlling SSID visibility and behavior directly affects which wireless networks devices can see and attempt to join. In shared office environments, multiple Wi-Fi networks may be present, increasing the risk of users accidentally connecting to the wrong network.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, SSIDs define how wireless networks are advertised and discovered. By modifying SSID settings-such as disabling broadcast or restricting auto-join behavior-technicians can prevent devices from attempting to connect to unauthorized or unintended networks.
The Travis Everett & Andrew Hutz - All-in-One Exam Guide explains that MDM solutions often preconfigure approved wireless profiles. Adjusting SSID configuration ensures devices only recognize and connect to sanctioned networks, reducing accidental associations and security risks.
The Mike Meyers / Mark Soper Lab Manual clarifies that IP filtering, content filtering, and port forwarding are network traffic control mechanisms. They do not prevent a device from seeing or attempting to connect to nearby Wi-Fi networks.
Because the goal is to prevent accidental Wi-Fi access, not filter traffic after connection, modifying SSID configuration is the correct and most effective solution.

This is likely arogue antivirusor scareware tactic. The user shouldnot click "OK"and instead check Windows Security (or third-party antivirus) status and ensure real-time protection is enabled.
FromMark Soper - Mike Meyers' Lab Manual:
"Users should verify security center settings if receiving suspicious pop-ups. Clicking unknown software updates can install malware. It's safer to validate protection through legitimate system tools."

The correct answer is C. The default gateway is not set, and this is clearly indicated by the ipconfig output showing the Default Gateway: 0.0.0.0. In TCP/IP networking, the default gateway is the router address that allows a workstation to communicate with networks outside its local subnet, including the internet. Without a valid default gateway, a device can only communicate with other devices on the same local network.
According to the Quentin Docter - CompTIA A+ Complete Study Guide, a missing or incorrect default gateway is one of the most common causes of a system being unable to access external resources. The guide explains that when a destination IP address is outside the local subnet, the workstation forwards the traffic to the default gateway. If no gateway is defined, the traffic has nowhere to go and is dropped.
The Travis Everett & Andrew Hutz - CompTIA A+ All-in-One Exam Guide reinforces that an IP address such as 10.203.10.22 with a subnet mask of 255.255.255.0 is valid for internal communication. The DNS suffix comptia.org is also not responsible for routing failures. DNS resolves names to IP addresses, but routing still requires a gateway.
The Mike Meyers / Mark Soper Lab Manual further clarifies that a subnet mask error would prevent even local communication, which is not indicated here. Because only external websites are unreachable, the absence of a default gateway is the definitive root cause.

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."
