A Virtual Private Network (VPN) is the best solution for providing encrypted remote access to email, file, and application servers. A VPN allows secure communication over a public network, such as the internet, by encrypting the data transmitted between the remote user and the company's internal network. This enables employees to access resources as if they were directly connected to the local network, while ensuring data privacy and security.

A. Disk-level encryption secures data on a physical disk but does not enable remote access.

B. Secure web gateway provides filtered internet access but is not designed for encrypted remote access to internal servers.

D. AES (Advanced Encryption Standard) is a specific encryption algorithm, but it is not a remote access solution on its own.

To view videos stored on a DVD, you need an optical drive. Optical drives are hardware devices capable of reading (and sometimes writing) data from optical discs like CDs, DVDs, and Blu-ray discs. These drives use a laser light to read the data encoded on the discs. For viewing DVD videos, the optical drive must support DVD media, which it decodes and sends to the computer for playback.

References: The use of optical drives for reading DVDs is commonly found in resources like the CompTIA IT Fundamentals exam guide, where they explain the functionality and necessity of different types of drives in computer systems.

Pseudocode is a high-level description of an algorithm or code that is used to outline a program in a way that is easily understood by humans without getting into the specifics of syntax in programming languages. It is often used for planning and discussing algorithms before coding begins. This makes it ideal for providing a rough draft of output or explaining how software processes should work.

References: The use of pseudocode is frequently emphasized in programming and software development documentation, including CompTIA IT Fundamentals study materials, as a vital step in the software development process.

The 802.11ac standard supports higher data rates, improved capacity, and better performance in dense environments. It offers significant improvements over previous standards like 802.11a, 802.11b, 802.11g, and 802.11n, with support for speeds up to several gigabits per second under optimal conditions. For a range of 115ft indoors and a speed of 700Mbps, 802.11ac is the most suitable choice due to its enhanced capabilities to handle higher speeds and greater ranges than its predecessors.References: Details about various Wi-Fi standards including their range and speed capabilities are covered in IT certifications such as CompTIA Network+ and are essential knowledge for IT professionals.
