When a user is in the office, the user's mobile phone loads applications and web browses very slowly on a cellular connection. Which of the following is the best way to fix this issue?
Connect to the company's Wi-Fi network.
The best way to fix the issue of slow cellular connection in the office is to connect to the company's Wi-Fi network. This will allow the user's mobile phone to access the internet through a faster and more reliable wireless network, instead of relying on the cellular network. Connecting to the Wi-Fi network will also save the user's data usage and battery life.
Some of the factors that can affect the cellular connection speed are the distance from the cell tower, the obstructions between the phone and the tower, the network congestion, the network technology, and the features of the phone12. In the office, the user may experience a weak or unstable cellular signal due to the building structure, the location, or the interference from other devices. Therefore, switching to the Wi-Fi network can improve the performance of the phone's applications and web browsing.

A technician receives an invalid certificate error when visiting a website. Other workstations on the same local network are unable to replicate this issue. Which of the following is most likely causing the issue?
Date and time is the most likely cause of the issue. The date and time settings on a workstation affect the validity of the certificates used by websites to establish secure connections. If the date and time are incorrect, the workstation may not recognize the certificate as valid and display an invalid certificate error. Other workstations on the same local network may not have this issue if their date and time are correct. User access control, UEFI boot mode, and log-on times are not likely causes of the issue. User access control is a feature that prevents unauthorized changes to the system by prompting for confirmation or credentials. UEFI boot mode is a firmware interface that controls the boot process of the workstation. Log-on times are settings that restrict when a user can log in to the workstation. None of these factors affect the validity of the certificates used by websites.Reference:

A homeowner recently moved and requires a new router for the new ISP to function correctly. The internet service has been installed and has been confirmed as functional. Which of the following is the FIRST step the homeowner should take after installation of all relevant cabling and hardware?
When a homeowner moves and sets up a new router for the new ISP it is important to take appropriate security measures to protect their network from potential security threats. The FIRST step that the homeowner should take after installation of all relevant cabling and hardware is to change the default passwords on new network devices.
Most modern routers come with default usernames and passwords that are widely known to potential attackers. If these defaults are not changed, it could make it easier for external attackers to gain unauthorized access to the network. Changing the passwords on new network devices is a simple but effective way to improve the security posture of the network.
