At ValidExamDumps, we consistently monitor updates to the CompTIA 220-1102 exam questions by CompTIA. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the CompTIA A+ Core 2 Exam exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by CompTIA in their CompTIA 220-1102 exam. These outdated questions lead to customers failing their CompTIA A+ Core 2 Exam exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the CompTIA 220-1102 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
A technician is helping a customer connect to a shared drive. The technician notices some unused drives that have already been mapped and wants to disconnect those drives first. Which of the following commands should the technician use?
Detailed
The net use (Option D) command is used to manage network drives in Windows. It can be used to display and disconnect mapped network drives, making it the correct choice for removing unused network drives.
format (Option A) is used to format disks, not for managing network drives.
netstat (Option B) displays network connections but doesn't manage network drives.
diskpart (Option C) is used for disk partitioning, not network drive management.
rmdir (Option E) is used to remove directories, not network drives.
CompTIA A+ Core 2 Reference:
1.2 - Use the appropriate Microsoft command-line tool, including net use for managing network drives .
A company installed WAPs and deployed new laptops and docking stations to all employees. The docking stations are connected via LAN cables. Users are now reporting degraded network service. The IT department has determined that the WAP mesh network is experiencing a higher than anticipated amount of traffic. Which of the following would be the most efficient way to ensure the wireless network can support the expected number of wireless users?
When a WAP (Wireless Access Point) mesh network is experiencing a higher than anticipated amount of traffic, leading to degraded network service, upgrading the network to a more advanced wireless standard can help alleviate the problem. The 802.11n specification, also known as Wireless-N, offers significant improvements over earlier standards like 802.11b/g in terms of speed, range, and reliability. It allows for increased data throughput and better coverage, which can support a higher number of wireless users effectively.
Upgrading to 802.11n: This involves replacing existing WAPs with those that support the 802.11n standard or higher. The upgrade can result in improved network performance by accommodating more wireless connections with higher data rates, reducing congestion and improving overall network efficiency.
Replacing non-mobile users' laptops with wired desktop systems (A) could reduce wireless traffic but may not be feasible or desirable for all users. Increasing the wireless network adapter metric (B) would affect route priority but not overall network capacity. Adding wireless repeaters (C) can extend the range but might also introduce additional latency and does not necessarily increase the network's capacity to handle more users efficiently.
Which of the following best describes XFS?
XFS is a high-performance filesystem created by Silicon Graphics in 1994 and is commonly used by Linux operating systems. It supports large files and directories and is known for its robustness and scalability. Other filesystems like NTFS (Windows), APFS (macOS), and HFS (macOS) are used on different platforms.
A field technician applied a Group Policy setting to all the workstations in the network. This setting forced the workstations to use a specific SNTP server. Users are unable to log in now. Which of the following is the MOST likely cause of this issue?
The workstations and the authentication server have a system clock difference. If a Group Policy setting is applied that forces the workstations to use a specific SNTP server, but the system clock on the workstations and the authentication server are out of sync, then this can cause authentication issues and users will be unable to log in. In this case, the most likely cause of the issue is a difference in system clocks and the technician should ensure that the clocks on the workstations and the authentication server are in sync.
A technician wants to harden Windows workstations after a recent security audit indicated the company is vulnerable to brute-force attacks. Which of the following features should the technician implement to mitigate such attacks?
To mitigate brute-force attacks, implementing a failed log-in lockout feature is effective. This security measure temporarily disables user accounts after a specified number of unsuccessful login attempts, preventing attackers from continuously trying different password combinations to gain unauthorized access.
