Q231. There are millions of insurance billing claims being sent out to hundreds of difference insurance carriers everyday, and with many different formats for claim forms and the need for error checking, there's a need for a service to manage electronic claims in one accessible format for billing offices to contact if there is a problem. If you have a problem with a billing transaction program, you will likely contact one of these services during your employment. What is the name of this kind of entity?
A. Medical Billing Clearinghouse
B. Insurance Server
C. Claims manager
D. Electronic traffic controller
Answer: A
Explanation: A healthcare billing clearinghouse receives from a healthcare provider's billing office an electronic claim and then scrubs it for potential errors, then the clearinghouse securely transmits the claim to the correct payer (insurer, government program, etc). Answer: D is incorrect. Although a clearinghouse may seem like an information "air traffic controller" this is not the proper name for the company. Answer: B is incorrect. This is not the correct term. Answer: C is incorrect. This is not what a claims manager does. A claims manager is a position within an insurance company.
Q232. Which of the following types of health insurance offers healthcare services for a prepaid, fixed amount of reimbursement?
A. Point of Service
B. Indemnity Plan
C. HMO
D. PPO
Answer: C
Explanation: Health Maintenance Organization (HMO) offers healthcare services for a prepaid fixed amount of reimbursement. In an HMO, providers and subscribers voluntarily enroll and the HMO assumes responsibility and financial risks. Answer: B is incorrect. Indemnity plan is incorrect as this type of plan allows you to visit any doctor, any hospital and direct your own care. Answer: D is incorrect. PPO or preferred provider organization is a network of physicians or healthcare organizations that provide healthcare at a discounted rate in return for higher patient volume. Answer: A is incorrect. Point of Service (POS) is an agreement where a patient is permitted to choose a provider each time healthcare service is required.
Q233. Which of the following typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet?
A. Terminal services
B. Application Virtualization
C. Thin client
D. Cloud computing
Answer: D
Explanation: Cloud computing typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. It provides common business applications online that are accessed from a web browser, while the software and data are stored on the servers. Answer: C is incorrect. A thin client is a low-cost computer, often legacy desktops, with limited resources. Thin clients run the latest operating systems (Windows 2000 Server and Windows Server 2003) and applications through special software such as the Terminal Services application. There is no requirement to install and configure applications on each computer, as the software are installeC, Donfigured in a centralized location on the server. Hence, the maintenance tasks are centralized. Answer: A is incorrect. Terminal Services is a multisession environment that provides remote computers access to Windows-based programs running on a server. When a user runs a program on a Terminal Server, the application execution takes place on the server, and only the keyboard, mouse and display information are transmitted over the network. Each user sees only his individual session, which is managed transparently by the server operating system, and is independent of any other client session. Answer: B is incorrect. Application virtualization is an umbrella term that describes software technologies that improve portability, manageability and compatibility of applications by encapsulating them from the underlying operating system on which they are executed.
Q234. Which of the following options of the IPCONFIG command is used to flush the leased IP address from Network Interface Card (NIC)?
A. /registerdns
B. /release
C. /showclassid
D. /renew
Answer: B
Explanation: The /release option of the IPCONFIG command is used to flush the leased IP address from Network Interface Card (NIC). Answer: D is incorrect. The /renew option is used to renew DHCP configuration for adapters or an specific adapter if the Adapter parameter is included. Answer: A is incorrect. The /registerdns option is used to initiate manual dynamic registration for the DNS names and IP addresses that are configured at a computer. Answer: C is incorrect. The /showclassid option of the IPCONFIG command is used to display the DHCP class ID for a specified adapter.
Q235. Your roommate is recovering from a cold, and you are feeling under the weather yourself. You are scheduled to update software on a workstation in the critical care center of a hospital. What should you do? Each correct answer represents a complete solution. Choose all that apply.
A. Wash hands thoroughly throughout the day, cover your mouth when you cough or sneeze and wash hands after any contact with bodily fluids.
B. Where a surgical mask while working.
C. Call in to your supervisor and explain that you may be ill and may need to work on an alternate project today.
D. Take cold medicine.
Answer: AC
Explanation: Depending on hospital policy, you may be asked to stay home or the day or be assigned to work in a department that does not have at-risk individuals nearby. Nosocomial infections, or infections acquired while in the hospital are a common and deadly problem, and what may seem like a simply cold to you could be deadly to a patient with a compromise immune system. At all times, maintain proper hand washing technique, washing your hands after any contact with bodily fluids, coughing, sneezing, shaking hands, or dealing with equipment that may be frequently touched. Precautions like this could save lives. Answer: D is incorrect. Taking cold medicine will not prevent you from passing an infection on to a patient who may have a weakened immune system. Hand washing and isolating yourself from patients if you suspect you may be ill are the best policy. Answer: B is incorrect. A surgical mask might prevent some kinds of infections, but most infections are relayed through hand contact with bodily fluids. Hand washing and isolation if you are coughing, sneezing and sick are the best policies.

Q237. Which of the following devices is used to read smart cards for user authentication?
A. PunchCard reader
B. Key fob
C. Biometric reader
D. Smart card reader
Answer: D
Explanation: A smart card reader is an interface device, which is used to read information from or write information to a smart card. Answer: B is incorrect. Key fobs are security devices used by telecommuters to provide one part of a three way match for a user to log on to a secured network.
These are display-only devices that algorithmically generate security codes as part of a challenge/response authentication system. This code usually changes very quickly and is used with the PIN for authentication. Answer: C is incorrect. Biometric devices are used for reading physical appearances. Biometrics is a method of authentication that uses physical characteristics, such as fingerprints, scars, retinal patterns, and other forms of biophysical qualities to identify a user. Nowadays, the usage of biometric devices such as hand scanners and retinal scanners is becoming more common in the business environment. Answer: A is incorrect. PunchCard readers are used for reading punch cards.
Q238. Which of the following statements is true about the installation of Universal Serial Bus (USB) devices?
A. A computer has to be restarted to install a USB device.
B. Software drivers are not required for USB devices.
C. USB devices are non-Plug and Play.
D. A USB device can be plugged to a computer without restarting it.
Answer: D
Explanation: Universal Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. It provides the Plug and Play capability of Windows to external hardware devices. USB supports hot plugging, which means that a USB device can be installed or removed while the computer is running. A single USB port can be used to connect up to 127 peripheral devices, such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a maximum data transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer rate of 480 Mbps. USB 2.0 is fully backward compatible with USB 1.1. Answer: B is incorrect. Software drivers are required for USB devices. It is possible, though, that the drivers for your USB devices are already available on the computer. In this case, you do not need to provide a device driver separately. Answer: A is incorrect. It is not required to restart the computer to install USB devices.
Q239. Which of the following tools are used to determine the hop counts of an IP packet? Each correct answer represents a complete solution. Choose two.
A. Netstat
B. TRACERT
C. ping
D. IPCONFIG
Answer: BC
Explanation: The ping and TRACERT tools are used to determine the hop counts of an IP packet. The ping command-line utility is used to test connectivity with a host on a TCP/IP-based network. This is achieved by sending out a series of packets to a specified destination host. On receiving the packets, the destination host responds with a series of replies. These replies can be used to determine whether or not the network is working properly. TRACERT utility is used to trace the path taken by TCP/IP packets to a remote computer. It traces and reports each router or gateway crossed by a TCP/IP packet on its way to the remote host. The TRACERT utility can be used with the target computer's name or IP address. It is used to detect and resolve network connection problems. Answer: A is incorrect. The netstat command displays protocol-related statistics and the state of current TCP/IP connections. It is used to get information about the open connections on a computer, incoming and outgoing data, as well as the ports of remote computers to which the computer is connected. The netstat command gets all this networking information by reading the kernel routing tables in the memory. Answer: D is incorrect. IPCONFIG is a command-line utility that displays the current TCP/IP configuration, such as the IP address, subnet mask, default gateway, etc. of a networked computer. It refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. Users can run IPCONFIG from the command prompt whenever they need to know the status of a computer's TCP/IP configuration.
Q240. 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
Answer: C
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.
