B. Web addresses
C. Fax numbers
D. Birth year if the patient(s) is under the age of 89
Explanation: Year information must only be deleted if patients are over the age of 90; however they can be aggregated into a single category "90 or older."
Q263. Which of the following stores document copies and backup media away from the computer center?
A. Storage area network
B. Network attached storage
C. On-site storage
D. Off-site storage
Explanation: Off-site storage refers to a location away from the computer center where document copies and backup media are kept. This storage method is more secure but less convenient and more costly. Answer: C is incorrect. On-site storage refers to the same location where the work place is. It is considered more convenient but less secure in case of disaster. Answer: A is incorrect. A storage area network (SAN) is an architecture to attach remote computer storage devices (such as disk arrays, tape libraries, and optical jukeboxes) to servers in such a way that the devices appear as locally attached to the operating system. Answer: B is incorrect. Network attached storage (NAS), in contrast to SAN, uses file-based protocols such as NFS or SMB/CIFS where it is clear that the storage is remote, and computers request a portion of an abstract file rather than a disk block.

Q265. Which of the following IEEE standards defines Ethernet and the use of copper cabling in a network?
A. ISO/IEC 11801
B. IEEE 802.1X
C. IEEE 802.3
D. IEEE 802.11i
Explanation: The IEEE 802.3 standards define the physical layer and the media access control (MAC) sublayer of the data link layer of a wired Ethernet. These standards are made for physical connections between nodes and infrastructure devices by various types of copper or fiber cable. Infrastructure devices include hubs, switches, routers, etc. The IEEE 802.3 standard also defines the use of copper cabling in a network. Answer: D is incorrect. 802.11i, also referred to as IEEE 802.11i-2004, is a standard for wireless local area networks (WLANs). It provides improved encryption for networks that use the popular 802.11a, 802.11b (which includes Wi-Fi), and 802.11g standards. It is an amendment to the original IEEE 802.11. The 802.11i standard requires new encryption key protocols, known as Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES). The 802.11i specification offers a level of security sufficient to satisfy most government agencies. However, AES requires a dedicated chip, and this may mean hardware upgrades for most existing Wi-Fi networks. Other features of 802.11i are key caching, which facilitates fast reconnection to the server for users who have temporarily gone offline, and pre-authentication, which allows fast roaming and is ideal for use with advanced applications such as Voice over Internet Protocol (VoIP). Answer: B is incorrect. IEEE 802.1X is an IEEE Standard for port-based Network Access Control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN, either establishing a point-to-point connection or preventing it if authentication fails. IEEE 802.1X defines the encapsulation of the Extensible Authentication Protocol (EAP) over IEEE 802 which is known as "EAP over LANs" or EAPOL. EAPOL was originally designed for IEEE 802.3 Ethernet in 802.1X-2001, but was clarified to suit other IEEE 802 LAN technologies such as IEEE 802.11 wireless and Fiber Distributed Data Interface (ISO 9314-2) in 802.1X-2004. The EAPOL protocol was also modified for use with IEEE 802.1AE (MACSec) and IEEE 802.1AR (Secure Device Identity / DevID) in 802.1X-2010. Answer: A is incorrect. International standard ISO/IEC 11801 specifies general-purpose telecommunication cabling systems (structured cabling) that are suitable for a wide range of applications (analog and ISDN telephony, various data communication standards, building control systems, factory automation). This standard is defined by ISO/IEC. It covers both balanced copper cabling and optical fiber cabling. The standard was designed for use within commercial premises that may consist of either a single building or of multiple buildings on a campus. It was optimized for premises that span up to 3 km, up to 1 km2 office space, with between 50 and 50,000 persons, but can also be applied for installations outside this range. A corresponding standard for small-office/home-office (SOHO) environments is ISO/IEC 15018, which also covers 1.2 GHz links for cable and satellite TV applications.
Q266. You are asked to install an information system in the Nuclear Medicine department in order to record the use of radioisotopes. Which type of information system would you install for this purpose?
A. Enterprise System
B. Departmental System
C. Intradepartmental System
D. External System
Explanation: A departmental information system is a system that is that is limited and serves the purposes of one department or domain. Examples are dose management systems that are used by pharmacies. Answer: A is incorrect. Enterprise system is incorrect as this type of system is designed for use for all departments that encompass a large health system including hospitals, clinics and nursing homes. Answer: D is incorrect. External system is incorrect as this type of system is shared by many health organizations to report information required by regulatory agencies or as an information exchange for regional health information networks. Answer: C is incorrect. Intradepartmental system is incorrect as this type of system is primarily used by one department but shares functions and information with other departments.

Q267. David, the Network Administrator for Portal Software Inc., is configuring his network for Internet connectivity. Which protocol should he use?
Explanation: TCP/IP is a very clean and efficient suite of standard protocols that governs how data passes between networks. It can be used on, both, local and wide-area networks (WANs), to provide communication between all the basic operating systems on the network. It is considered the primary protocol of the Internet and the World Wide Web. NetBEUI is a non-routed, broadcast-based protocol. The master browser on TCP/IP networks cannot see, or display, computers that use NetBEUI to communicate with the network in the network browser list. NetBEUI was used as a legacy protocol for networking between Windows 3.1 and MS-DOS clients.IPX/SPX is Novell's primary network protocol, used for the interchange of files between NetWare and other networking clients. Although it has many positive features to its credit, such as that it is easy to install and is dynamic in that it requires no configuration changes for either mobile or relocated network nodes; it is not considered a good protocol for use on WANs. This is because it relies on network-wide broadcasts, which makes overhead unreasonably high for effective WAN implementations. Hence it is not considered an Internet protocol.Microsoft developed NWLink, it is an IPX/SPX-compatible protocol, and again is not the choice for Internet. Reference. TechNet, Contents.

Q268. Which of the following statements is true about modem?
A. It converts digital signals into analog signals and vice versa.
B. It converts AC current to DC current and vice versa.
C. It reduces the noise in analog signal.
D. It amplifies the digital signals.
Explanation: Modem converts digital signals into analog signals and vice versa. Modem is a device used by computers to communicate over long distances through Public Service Telephone Lines (PSTN). Modem stands for Modulator and Demodulator. When a computer sends data, it uses digital signals. Modem converts these digital signals into analog signals and transmits the data over PSTN. At the receiving end, modem converts the analog signals back to digital signals and delivers to the receiving computer.
