A company recently enabled two-factor authentication in order to enhance security. Users should be prompted for two-factor authentication when working outside of the office, but are also being prompted when connecting to the office Wi-Fi. Which of
the following should the technician do?
Correct Answer:
B
Allow listing is a security technique that allows only specific IP addresses or domains to access a network or a service. By adding the office IP address as an exception, the company can prevent two-factor authentication from being triggered when users are connected to the office Wi-Fi, since the office network is considered trusted. This way, users will only be prompted for two-factor authentication when working outside of the office, which enhances security.

A tier one technician has spent the past thirty minutes troubleshooting an Issue With an end user's network connection After a solution was implemented, the end user rebooted the system, tested the Issue, and confirmed the Issue was resolved. Which of the following should the technician do NEXT?
Correct Answer:
A
According to the Official CompTIA A+ Core 1 Study Guide (220-1101) 1, the correct answer is A. Document the findings, actions, and solution in the company knowledge base.
The explanation is that after resolving an issue, a technician should always document what was done and how it was fixed. This helps to create a record of the problem and its solution for future reference and also to share knowledge with other technicians. https://www.comptia.org/training/books/a-core-1-220-1101-study-guide
By documenting the findings, actions, and solution in the company knowledge base, it will help to ensure that if the Issue happens again, the technician or a different technician will be able to quickly and easily find the solution and resolve the Issue. Additionally, it is important to document the solution so that the same Issue does not need to be troubleshot multiple times in the future.

A laptop does not have any audio output from the built-in speakers. The Windows Device Manager shows a down arrow for the audio device. Which of the following will correct this audio issue?
Correct Answer:
C
Enabling the audio device is the correct action to correct an audio issue where a laptop does not have any audio output from the built-in speakers and Windows Device Manager shows a down arrow for the audio device. A down arrow indicates that the audio device is disabled and needs to be enabled by right-clicking on it and selecting Enable device. Replacing the speakers, increasing the volume, or updating the driver are unlikely to solve the issue if the audio device is disabled.

A user with a self-configured, static IP address cannot connect to the internet. The technician runs an ipconfig command and receives the following output:
Which of the following should the technician edit?
Correct Answer:
D
The correct answer is D. Default gateway.
A default gateway is the device that connects a local network to other networks, such as the internet. A default gateway is usually a router or a modem that has an IP address on the same subnet as the local network. A default gateway is necessary for a device to communicate with devices outside its local network.
In this case, the user has a self-configured, static IP address of 192.168.1.20, which belongs to the subnet 192.168.1.0/24 (with a subnet mask of 255.255.255.0). However, the default gateway is set to 192.168.0.1, which belongs to a different subnet (192.168.0.0/24). This means that the user’s device cannot reach the default gateway, and therefore cannot connect to the internet.
The technician should edit the default gateway to match the correct subnet of the user’s device, such as 192.168.1.1 or 192.168.1.254, depending on the configuration of the network.

A technician is upgrading the memory on a server that processes payment information online. Which of the following types of memory would the technician most likely install?
Correct Answer:
D
ECC stands for Error Correction Code, which is a type of memory that can detect and correct data errors that may occur during processing or transmission. ECC memory is commonly used in servers that handle sensitive or critical information, such as payment information online, because it can reduce the risk of data corruption, system crashes, or security breaches12.
DDR4 is a generation of DDR technology, which stands for Double Data Rate. DDR4 memory is faster and more power-efficient than its predecessors, but it does not necessarily have ECC functionality. DDR4 memory can be either ECC or non-ECC1. VRAM is Video RAM, which is a type of memory that is dedicated to storing graphics data for display. VRAM is usually found on graphics cards or integrated graphics processors, not on servers3.
SODIMM is Small Outline DIMM, which is a type of memory module that has a smaller size and lower profile than regular DIMMs. SODIMMs are typically used in laptops, notebooks, or other compact devices, not on servers3.
