Trusted Computer System Evaluation Criteria (TCSEC)
Advanced Configuration and Power Interface (ACPI)
Answer: A Explanation:
Energy Star rating is an international standard for energy efficient consumer products.
The Energy Star rating is an international standard for energy efficient consumer products. Devices carrying the Energy Star logo are products, such as computerdevices, peripherals, kitchen appliances, etc. These products generally use 20% to 30% lesser energy than required by the federal standards. The Energy Star program was created by the #39;United
States Environmental Protection
Agency#39; (US EPA) as an attempt to reduce energy consumption and greenhouse gas emission by power plants. The program has helped in spreading the use of LED traffic lights, efficient fluorescent lighting, and power management systems for office equipments. Answer option C is incorrect. Trusted Computer System Evaluation Criteria (TCSEC), frequently referred to as the Orange Book, is the centerpiece of the DoD Rainbow Series publications. It is a
United States Government Department of Defense (DoD) standard that sets basic requirements forassessing the effectiveness of computer security controls built into a computer system. TCSEC was used to evaluate, classify and select computer systems being considered for the processing, storage and retrieval of sensitive or classified information. It was replaced with the development of the
Common Criteria international standard originally published in 2005.
Answer option B is incorrect. The standby mode is a power saving feature for computers. In this mode, a computer does not shut down completely. Thecomputer goes to low power state and, as a result, it consumes less power. When the computer resumes from the standby mode, full power is restored to its devices. During the standby mode, if the power supply is disconnected or interrupted, data might be lost. The standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do not need to enable this mode manually.
This mode is not available in non-ACPI and non-APM based computers.
Answer option D is incorrect. The Advanced Configuration and Power Interface (ACPI) is a powermanagement specification developed by Intel, Microsoft, and Toshiba. It enables an operating system to control the amount of power supplied to each device attached to a computer by turning off peripheral deviceswhen they are not in use. Itdefines power management on a wide range of mobile, desktop, and server computers and peripherals. It also enables manuurers to produce computers that automatically power up as soon as a user touches the keyboard. Reference. quot;http.//en.wikipedia.org/wiki/Energy_Starquot;

Which of the following storage device uses SRAM or DRAM?
USB flash drive
Solid-state drive (SSD)
Answer: B Explanation:
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive interface, thus easily replacing itin most applications. It is also known as solid-state hard disk drive. SSDs have no moving parts; hence, they are less fragile and silent than hard disks. As there are no mechanical delays, SSDs usually enjoy low access time and latency. An SSD using SRAMor DRAM (instead of flash memory) is often called a RAM-drive, which should not be confused with a RAM disk. Answer option C is incorrect. Blu-ray Disc, also known as Blu-ray or BD, is an optical disc
storage medium. It is designed to supersede the standard DVD format for storing high- definition video,
PlayStation 3 games, and other data, with up to 25 GB per single layered, and 50 GB per dual layered disc. Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. The disc has the same physical dimensions as standard DVDs and CDs. It is called Blu-ray Disc because of the blue-violet laser which is used to read the disc. Blu-ray uses ashorter wavelength, a 405 nm blue-violet laser, and allows for almost six times more data storage than on a DVD.
Answer option D is incorrect. CD drive is used for read/write operations on CDs. The CD drives that are capable of performing write operations on CDs are also known as CD burners. However, most of the CD drives on computers have read only capability. CD drives with read-only capability are also known as CD-ROM (Compact Disc Read-Only Memory) drives. A CD drive is installed inside the computer case and can be connected to IDE,SCSI, SATA, or firewire interface.
Answer option A is incorrect. A USB flash drive consists of flash memory data storage device integrated with a USB (Universal Serial Bus) 1.1 or

Your customer is very concerned about security for Wi-Fi at his home. He wants to make sure that only computers, he has authorized, can get on his Wi-Fi. What is the most appropriate security measure you can recommend?
Answer: C Explanation:
Mac filtering only allows computers, which have their MAC address listed with the router, to connect.
What is MAC address filtering?
MAC address filtering is a security method that enables a device to allow only certain MAC addresses to access a network. It can be configured on a Wireless Access Point (WAP) to allow only certainsystem MAC addresses to communicate with the rest of the network.
MAC address filtering can be performed using either of the two policies. exclude all by default, then allow only listed clients; or include all by default, then exclude listed clients. MACfiltering can also be used on a wireless network to prevent certain network devices from accessing the wireless network. MAC addresses are allocated only to hardware devices, not to persons.
Answer options D and B are incorrect. Any encryption will be based on password authentication, not on filtering specific computers. Only MAC filtering will do that. Answer option A is incorrect. A firewall will not prevent people or computers from connecting to your Wi-Fi. It will block certain, unwanted connections.
