220-1101 Practice Test

Explanation: Client virtualization involves installing an application on a server and enabling multiple users to run the application simultaneously via virtualized sessions. This eliminates the need for individual installations on local machines.
✑ Why Not B (Software as a Service): SaaS delivers software over the internet and does not require local installations but is managed by a third party, not the organization itself.
✑ Why Not C (Sandboxing): Sandboxing is for isolating applications for security testing, not for concurrent user access.
✑ Why Not D (Embedded software): Embedded software is installed on hardware devices, not shared across multiple users.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 4.2, virtualization concepts.

Explanation: VDI (Virtual Desktop Infrastructure) allows users to access a desktop environment that is running on a server in the data center rather than on the local machine. This is particularly useful for employees who need to work remotely on various devices (A), as it provides a consistent and secure environment regardless of the endpoint device. For a bank with security concerns regarding employee activity (D), VDI offers a centralized management of desktops, enhancing security by keeping sensitive data and applications within the data center and not on the local devices, thus reducing the risk of data breaches.

Explanation: Two-factor authentication (2FA) significantly enhances security by requiring two forms of verification before granting access to company resources, making it harder for unauthorized users to gain access even if they have one of the credentials. PIN code enforcement adds an additional layer of security by ensuring that devices are protected by a PIN, making physical access to the device more challenging for unauthorized users. While the other options provide various benefits, 2FA and PIN code enforcement directly enhance the security of remote users accessing company resources.

✑ CompTIA A+ Core 1 Exam Objectives Section 2.7: Compare and contrast Internet connection types, network types, and their features.

Explanation: The connection type that the technician should recommend is Satellite. Satellite internet is a good option for people who travel around the world and want to have connectivity while visiting remote camping locations. It works by using terminals which can give you internet access in remote locations as long as they have a line of sight to the satellite in orbit above12.

Since the customer travels to remote camping locations with limited or unreliable cellular service, the best recommendation is satellite internet connection. Satellite internet uses a dish to connect to satellites orbiting the earth, which can provide coverage anywhere in the world as long as there is a clear line of sight to the satellite. This is especially useful in remote areas where traditional terrestrial connections are not available.

Explanation: The MOST efficient next step the technician should complete is to check the printer paper path to locate any obstructions1. The error message “Paper Jam, Jam in fuser” indicates that there is a paper jam in the fuser2. The fuser is one of the parts of a laser printer most likely to fail without giving any explicit message2. The printer LCD screen indicates a paper jam in the fuser. The most efficient next step the technician should complete is to check the printer paper path to locate any obstructions. Applying a maintenance kit or replacing the fuser may not be necessary if the issue is caused by a paper jam.
