CompTIA A+ Certification Exam: Core 2 220-1202 Prüfungsfragen mit Lösungen (Q51-Q56):

51. Frage
A user reports that their internally hosted CRM application splash screen attempts to load, pauses for a few seconds, and then disappears. A technician installs the application software on their computer and is able to recreate the issue. When checking the application logs, the technician sees the following:
Windows could not start the CRM Service on Local Computer 10169. The
service did not start due to a log-on failure.
Which of the following would most likely cause this issue?

Antwort: C

Begründung:
The log entry indicates the CRM service cannot start due to a log-on failure, which most commonly occurs when the service account used to run the application (often an LDAP/domain service account) is disabled or has incorrect credentials. This prevents the required background service from starting and causes the application to close immediately.


52. Frage
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?

Antwort: D

Begründung:
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


53. Frage
When a corporate laptop is connected to the company network, it can reach external websites. However, it cannot reach any internal websites, displaying the error message "Cannot reach this page." Which of the following should a technician configure?

Antwort: B

Begründung:
Comprehensive and Detailed Explanation From Exact Extract:
If internal resources (such as intranet or internal apps) can't be accessed but external sites work, this often points to aDNS issue, where the system isn't resolving internal domain names correctly.
FromAll-in-One Exam Guide:
"When internet access is functional but internal sites fail to load, the issue usually lies with DNS resolution.
Internal resources often require internal DNS servers, which may not be configured correctly."


54. Frage
A technician must update a user's laptop to the latest OS. After multiple failed attempts, the technician confirms that the laptop is connected to Wi-Fi and supports the latest update. Which of the following should the technician do next to resolve the issue?

Antwort: C

Begründung:
The correct answer is A. Verify that storage space is available. The question already confirms two major requirements: the laptop has Wi-Fi connectivity and supports the latest update. The next most likely cause is insufficient storage. Quentin Docter's Complete Study Guide explains that when a mobile OS fails to update, the technician should check compatibility, connectivity, and storage. It specifically states that enough storage space must be available because, during an update, both the current operating system and the upgrade files may need to exist on the device. The Mike Meyers/Mark Soper material also identifies the df command as useful for listing used and available storage space on macOS or Linux systems, showing how important available storage is when diagnosing update and system issues. Airplane mode is unlikely because Wi-Fi was already confirmed. Antivirus scans and unauthorized software checks may be useful later, but storage should be checked next.


55. Frage
After a user installs a mobile application from an advertisement, the phone ' s battery dies a few hours later and becomes hot to touch, even when not in use. Which of the following should a technician do first?

Antwort: D

Begründung:
These symptoms strongly indicatemalware infectionor a malicious app running in the background. The first action should be torun a malware scanto identify and remove malicious components.
FromQuentin Docter - CompTIA A+ Complete Study Guide:
"If a mobile device is overheating and the battery drains rapidly after installing an app, this could point to malware. Begin by scanning the device with a mobile anti-malware application."
