What activities does the Computer Misuse Act 1990 make illegal?

Answer: An Act which makes illegal a number of activities such as deliberately planting viruses, hacking, using ICT equipment for fraud.

The Computer Misuse Act 1990 is a landmark piece of UK legislation designed to criminalize various forms of unauthorized access and misuse of computer systems. It specifically makes illegal activities such as unauthorized access to computer material (hacking), unauthorized access with intent to commit further offenses, and unauthorized modification of computer material (like planting viruses or using computers for fraud). This act was crucial in establishing legal boundaries for computer-related crimes.

Contains the boot options for machines running the NT-based operating system before Windows Vista on BIOS firmware.

Answer: %SYSTEMDRIVE%\boot.ini

Before Windows Vista, NT-based operating systems on BIOS firmware used the `%SYSTEMDRIVE%\boot.ini` file to define boot options. This text file contained entries for each operating system installed, allowing users to select which OS to boot and configure various startup parameters. With Windows Vista and later, Microsoft transitioned to the Boot Configuration Data (BCD) store, replacing `boot.ini`.

Private Internet Protocol Addressing Automatically

Answer: APIPA

APIPA stands for Automatic Private IP Addressing. It is a feature in Windows operating systems that automatically assigns an IP address to a client when no DHCP server is available on the network. These IP addresses fall within the 169.254.0.0/16 range, allowing devices to communicate on a local segment even without a configured DHCP server.

Which network port number is commonly associated with the TACACS (Terminal Access Controller Access-Control System) protocol?

Answer: TACACS

The question asks for the network port number associated with TACACS, but the correct answer provided is 'TACACS' itself. TACACS (Terminal Access Controller Access-Control System) is an older authentication protocol. It typically uses TCP port 49 for communication, distinguishing it from its successor, TACACS+, which also uses port 49, and RADIUS, which uses UDP ports 1812/1813.

What does the acronym GWS typically refer to in the context of web servers?

Answer: Google Web Server

GWS stands for Google Web Server, which is proprietary web server software developed by Google. It is used to host Google's own websites and services. While not publicly available for general use, GWS is a significant player in the web server landscape, handling a vast amount of internet traffic for Google's ecosystem.

Which operating systems are commonly associated with the "IIS 8.5 Defaults" in the context of web server software?

Answer: Windows Server 2012 R2, Windows 8.1

IIS 8.5 was introduced with Windows Server 2012 R2 and Windows 8.1. This version brought enhancements such as enhanced logging, dynamic IP address restrictions, and idle worker process page-out, improving performance and security for web hosting environments. It was a significant update from IIS 8.0, which shipped with Windows Server 2012 and Windows 8.

A copy of each router's routing table is transmitted to its nearby neighbors. In order to account for the additional distance to the end network, the neighbor increases the metric when adding the route to its own table. The distance is specified as the number of hops, and the vector component contains the location of the following hop.

Answer: Distance Vector Routing

Distance Vector Routing is a class of routing protocols where each router maintains a routing table containing the 'distance' (e.g., hop count) and 'vector' (next hop) to reach other networks. Routers periodically exchange their entire routing tables with their directly connected neighbors, which then update their own tables by adding the neighbor's reported distance to their own cost to reach that neighbor. This iterative process allows routing information to propagate across the network.
