最新的 A+ 220-1202 免費考試真題 (Q155-Q160):

問題 #155
A user is seeing authentication errors in applications and certificate errors when browsing. A technician verifies the following:
* The gateway is reachable.
* The local server fileshares are accessible without issue.
Which of the following is the issue?

答案：D

解題說明：
Because the gateway and internal file shares work, the device has basic network connectivity. The two symptoms that remain- certificate errors and authentication errors -share a very common underlying cause: incorrect system time. Quentin Docter explains that certificate problems often come from " the proper setting of time and date ," stating that " The time on the host should always be checked along with the expiration of the SSL certificate." If the clock is wrong, certificates can appear "not yet valid" or "expired," triggering browser certificate warnings even when the site is fine.
Mike Meyers also ties time drift directly to authentication failures: " All clocks-including those in computers-experience time drift... This clock drift can cause problems with time-sensitive applications and services (especially authentication services). " That matches the exact scenario: apps show authentication errors while browsing shows certificate errors. Duplicate IP or DHCP "bad address" typically causes intermittent or total connectivity problems (which would likely break file shares), not specifically certificate/auth failures. Therefore, time drift is the best diagnosis.


問題 #156
A technician verifies that a malware incident occurred on some computers in a small office. Which of the following should the technician do next?

答案：D

解題說明：
Once a malware incident has been confirmed, the immediate next step is to contain the threat. Quarantining infected systems prevents the malware from spreading to other devices and isolates the malicious code for further analysis or remediation.
B). Educating end users is important but occurs later in the incident response process.
C). Disabling System Restore is part of cleanup, not containment.
D). Updating and scanning should occur after the system is quarantined to prevent further infection or spread.

問題 #157
A small non-profit organization is looking to replace its aging desktop computers. The organization has a very limited budget and wants to avoid expensive per-seat licensing fees. Additionally, the customer is concerned about data privacy and strictly requires that all files be kept locally on the devices rather than in the cloud. Which of the following operating systems should the technician recommend?

答案：C

解題說明：
The key requirements are (1) avoid expensive licensing fees and (2) keep files locally . Linux best matches both. Quentin Docter explains that open source software is "freer than free," meaning the application is free and the source code is shared, and he explicitly lists " OSs such as Linux " as open source examples. That directly supports the licensing-cost goal. By contrast, Windows and macOS are commercial, licensed operating systems.
Chrome OS often works best when users rely heavily on cloud-based services and synchronization, which conflicts with the customer's preference that "all files be kept locally" (even though local storage exists, Chrome OS is commonly positioned around cloud workflows). Linux supports fully local file storage and gives the organization control over storage location, backup choices, and offline access.
The All-in-One guide reinforces the idea that some developers (including Linus Torvalds for Linux) made software "freely available for everyone," highlighting Linux as a no-licensing-fee option compared with commercial licensing models. Therefore, the best recommendation is Linux (A) .


問題 #158
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?

答案：B

解題說明：
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."


問題 #159
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?

答案：A

解題說明：
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.
