100BaseTX is a 100-Mbps baseband Fast Ethernet specification using two pairs of either UTP or STP wiring. The first pair of wires is used to receive data; the second is used to transmit. To guarantee proper signal timing, a 100BaseTX segment cannot exceed 100 meters in length. This specification of Ethernet is based on the IEEE 802.3 standard.

Asymmetric digital subscriber line (ADSL) is designed to provide more bandwidth downstream (1 to 8 Mbps) than upstream (16 to 800Kb). DSL (Digital Subscriber Line) is a modem technology for broadband data access over ordinary copper telephone lines (POTS) from homes and businesses. xDSL refers collectively to all types of DSL, such as ADSL (and G.Lite), HDSL, SDSL, IDSL and VDSL etc. They are sometimes referred to as last-mile (or first mile) technologies because they are used only for connections from a telephone switching station to a home or office, not between switching stations.
xDSL is similar to ISDN in as much as both operate over existing copper telephone lines (POTS)
using sophisticated modulation schemes and both require the short runs to a central telephone

The following are incorrect answers:
Single-line Digital Subscriber Line (SDSL) deliver 2.3 Mbps of bandwidth each way.
High-rate Digital Subscriber Line (HDSL) deliver 1.544 Mbps of bandwidth each way.
Very-high data-rate Digital Subscriber Line (VDSL) can deliver up to 52 Mbps downstream over a
single copper twisted pair over a relatively short distance (1000 to 4500 feet).

The primary benefits of employing an incident-handling capability are containing and repairing damage from incidents and preventing future damagE. Additional benefits related to establishing an incidenthandling capability are: Enhancement of the risk assessment process. An incidenthandling capability will allow organizations to collect threat data that may be useful in their risk assessment and safeguard selection processes (e.g., in designing new systems). Statistics on the numbers and types of incidents in the organization can be used in the risk-assessment process as an indication of vulnerabilities and threats. Enhancement of internal communications and the readiness of the organization to respond to any type of incident, not just computer security incidents. Internal communications will be improved, management will be better organized to receive communications, and contacts within public affairs, legal staff, law enforcement, and other groups will have been preestablished. Security training personnel will have a better understanding of users knowledge of security issues. Trainers can use actual incidents to vividly illustrate the importance of computer security. Training that is based on current threats and controls recommended by incident-handling staff provides users with
information more specifically directed to their current needs,
thereby reducing the risks to the organization from incidents.
*Answer "An individual acting alone would not be able to subvert a security process or control" is a
benefit of employing separation of duties controls.
