Switch-based network monitoring requires additional monitoring software or hardware because switches operate at the data link layer of the OSI model and do not inherently provide monitoring capabilities. To monitor traffic through a switch, network administrators must use port mirroring or a network tap, which involves configuring the switch to send a copy of the network packets to a monitoring device. This allows the monitoring device to analyze the traffic passing through the switch without interfering with the network's normal operation. This technique is essential for deep packet inspection, intrusion detection systems, and for gaining visibility into the traffic between devices in a switched network.

The NIST Risk Management Framework (RMF) is a structured process that integrates security, privacy, and cyber supply chain risk management activities into the system development life cycle (SDLC). It provides a disciplined and structured process that integrates information security and risk management activities into the SDLC. The RMF is designed to help organizations manage the security of their information systems by guiding them through a step-by-step process that includes categorizing information systems, selecting and implementing appropriate security controls, assessing the effectiveness of the controls, authorizing information system operation, and continuously monitoring the security state of the system.

To allow a file to be editable, viewable, and deletable by everyone, Henry needs to set the file permissions to the most permissive value. In Linux and Unix systems, file permissions are represented by three sets of three bits, each set representing permissions for the owner, the group, and others.
The permission value of 777 means:
The first digit (7) grants read (4), write (2), and execute (1) permissions to the owner. The second digit (7) grants read, write, and execute permissions to the group. The third digit (7) grants read, write, and execute permissions to others. Setting the permissions to 777 ensures that everyone (owner, group, and others) can read, write, and execute the file. This aligns with the requirement for the file to be editable, viewable, and deletable by everyone.

The 802.11b protocol is the correct choice for the network administrator to satisfy the specified requirements. This protocol operates in the 2.4 GHz frequency band, uses Direct-Sequence Spread Spectrum (DSSS) for modulation, and provides a data rate of up to 11 Mbits/s, which is well above the minimum requirement of 2 Mbits/s. The 802.11b standard also uses a channel width of 22 MHz, which matches the given specification. It was designed to be backward compatible with the original 802.11 standard and is widely used due to its range and compatibility with many devices.
