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?
Correct Answer: D
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.
Question 257
Which of the following would typically require the most computing resources from the host computer?
Correct Answer: B
Windows is the operating system that typically requires the most computing resources from the host computer, compared to the other options. Computing resources include hardware components such as CPU, RAM, disk space, graphics card, and network adapter. The minimum system requirements for an operating system indicate the minimum amount of computing resources needed to install and run the operating system on a computer. The higher the minimum system requirements, the more computing resources the operating system consumes. According to the web search results, the minimum system requirements for Windows 10 and Windows 11 are as follows12: CPU: 1 GHz or faster with two or more cores (Windows 10); 1 GHz or faster with two or more cores on a compatible 64-bit processor (Windows 11) RAM: 1 GB for 32-bit or 2 GB for 64-bit (Windows 10); 4 GB (Windows 11) Disk space: 16 GB for 32-bit or 32 GB for 64-bit (Windows 10); 64 GB (Windows 11) Graphics card: DirectX 9 or later with WDDM 1.0 driver (Windows 10); DirectX 12 compatible with WDDM 2.0 driver (Windows 11) Network adapter: Ethernet or Wi-Fi (Windows 10); Ethernet or Wi-Fi that supports 5 GHz (Windows 11) The minimum system requirements for macOS Ventura are as follows: CPU: Intel Core i3 or higher, or Apple M1 chip RAM: 4 GB Disk space: 35.5 GB Graphics card: Metal-capable Network adapter: Ethernet or Wi-Fi The minimum system requirements for Chrome OS are as follows: CPU: Intel Celeron or higher RAM: 2 GB Disk space: 16 GB Graphics card: Integrated Network adapter: Ethernet or Wi-Fi The minimum system requirements for Android are as follows: CPU: 1 GHz or higher RAM: 512 MB Disk space: 8 GB Graphics card: OpenGL ES 2.0 Network adapter: Ethernet or Wi-Fi The minimum system requirements for Linux vary depending on the distribution, but a common example is Ubuntu, which has the following minimum system requirements: CPU: 2 GHz dual core processor or better RAM: 4 GB Disk space: 25 GB Graphics card: 1024 x 768 screen resolution Network adapter: Ethernet or Wi-Fi Based on the comparison of the minimum system requirements, Windows has the highest requirements for CPU, RAM, disk space, and graphics card, while Chrome OS and Android have the lowest requirements. macOS and Linux have moderate requirements, depending on the hardware and software configuration. Therefore, Windows is the operating system that typically requires the most computing resources from the host computer.

Question 258
A technician needs to recommend the best backup method that will mitigate ransomware attacks. Only a few files are regularly modified, however, storage space is a concern. Which of the following backup methods would BEST address these concerns?
Correct Answer: B
The differential backup method would best address these concerns. Differential backups only back up files that have changed since the last full backup, which means that only a few files would be backed up each time. This would help to mitigate the risk of ransomware attacks, as only a few files would be affected if an attack occurred. Additionally, differential backups require less storage space than full backups.
Question 259
Which of The following refers to the steps to be taken if an Issue occurs during a change Implementation?
Correct Answer: B
Rollback refers to the steps to be taken if an issue occurs during a change implementation. It means restoring the system to its previous state before the change was applied, using backup data or configuration files. It can minimize the impact and downtime caused by a failed change. Testing refers to the steps to be taken before a change implementation, to verify that the change works as expected and does not cause any errors or conflicts. Risk refers to the potential negative consequences of a change implementation, such as data loss, security breach, performance degradation, etc. Acceptance refers to the steps to be taken after a change implementation, to confirm that the change meets the requirements and expectations of the stakeholders.

Question 260
A user contacts a technician about an issue with a laptop. The user states applications open without being launched and the browser redirects when trying to go to certain websites. Which of the following is MOST likely the cause of the user's issue?
Correct Answer: D
Explanation The most likely cause of the user's issue of applications opening without being launched and browser redirects when trying to go to certain websites is malware. Malware is a general term that refers to any software or code that is malicious or harmful to a computer or system. Malware can perform various unwanted or unauthorized actions on a computer or system, such as opening applications, redirecting browsers, displaying ads, stealing data, encrypting files or damaging hardware. Malware can infect a computer or system through various means, such as email attachments, web downloads, removable media or network connections. Keylogger is a type of malware that records and transmits the keystrokes made by a user on a keyboard. Keylogger can be used to steal personal or sensitive information, such as passwords, credit card numbers or chat messages. Keylogger does not typically open applications or redirect browsers but only captures user inputs. Cryptominers are a type of malware that use the computing resources of a computer or system to mine cryptocurrency, such as Bitcoin or Ethereum. Cryptominers can degrade the performance and increase the power consumption of a computer or system. Cryptominers do not typically open applications or redirect browsers but only consume CPU or GPU cycles. Virus is a type of malware that infects and replicates itself on other files or programs on a computer or system.
