A user installs a wireless router and opens a browser to modify the settings. Which of the following installation types does this describe?
Correct Answer: A
A web-based installation is a type of installation that uses a web browser to access and configure the settings of a device, such as a wireless router. A web-based installation typically requires the user to enter the IP address of the device in the browser's address bar, and then log in with a default username and password. The user can then modify the settings of the device according to their preferences and needs. A web-based installation is different from other types of installations, such as plug-and-play, driver-based, and server-based, which do not use a web browser to configure the device.

Question 62
Which of the following should have the HIGHEST expectation of privacy?
Correct Answer: C
A locally stored word processing document would have the highest expectation of privacy among the given options. Privacy is the right or ability of individuals or groups to control or limit the access or disclosure of their personal information by others. A locally stored word processing document is a file that contains text, images, or other data that is created and saved on a device's internal storage, such as a hard drive or SSD. A locally stored word processing document can have a higher level of privacy than a file that is shared, uploaded, or transmitted over the Internet or a network, because it is less exposed to potential threats or breaches. However, a locally stored word processing document may still require additional security measures, such as encryption, password protection, or backup, to ensure its privacy and integrity.

Question 63
Which of the following would be the most cost-effective method to increase availability?
Correct Answer: D
Availability is the measure of how accessible a system or service is to its users. Availability can be affected by various factors, such as hardware failures, software bugs, network outages, natural disasters, human errors, and malicious attacks. To improve availability, organizations can use various methods, such as redundant equipment, disaster recovery sites, continuity plans, and scheduled maintenance. However, not all methods have the same cost-effectiveness. Redundant equipment is the practice of having backup or spare components that can take over the function of a failed component. This can improve availability by reducing the impact of hardware failures, but it also increases the cost of purchasing, installing, and maintaining the extra equipment. Disaster recovery site is a location where an organization can resume its operations after a major disruption, such as a fire, flood, or earthquake. This can improve availability by allowing the organization to continue providing its services in the event of a catastrophic event, but it also requires a significant investment in infrastructure, security, and data replication. Continuity plan is a document that outlines the procedures and resources needed to restore normal operations after a disruption. This can improve availability by ensuring that the organization has a clear and consistent plan to follow in case of an emergency, but it also requires time and effort to develop, test, and update the plan. Scheduled maintenance is the practice of performing regular checks and repairs on the system or service to prevent or fix potential issues. This can improve availability by reducing the likelihood and severity of failures, but it also requires planning, coordination, and downtime. Among these methods, scheduled maintenance is the most cost-effective, because it does not require additional equipment, infrastructure, or data replication, and it can prevent or mitigate many common causes of unavailability. Scheduled maintenance can also help extend the lifespan and performance of the existing components, reducing the need for replacements or upgrades.

Question 64
A building has two legacy APs. A new AP was recently installed within 30ft (9m) of the legacy APs. Multiple users have been reporting intermittent internet connectivity since the new AP was installed. Which of the following explains what is happening?
Correct Answer: B
The intermittent internet connectivity experienced by users since the installation of the new AP is likely due to interference and attenuation. When wireless access points are placed too closely together (in this case, within 30 feet), they can cause interference, especially if they are operating on overlapping channels. Attenuation refers to the weakening of wireless signals as they travel through obstacles or over distance. A . WEP is enabled is related to security and is unlikely to cause connectivity issues. C . There are speed limitations would cause slow performance, not intermittent connectivity. D . The passwords are not synced would result in connectivity denial, not intermittent access.

Question 65
Which of the following is an advantage of installing an application to the cloud?
