Internet Services Providers ISPs through the world C. Internet Service Providers ISPs throughout the world D. Internet Service Providers ISPs throughout the world. To improve the integrity of asynchronous communications in the realm of personal computers, the Microcom Networking Protocol MNP uses a highly effective communications error control technique known as A. Cyclic redundancy check. B. Vertical redundancy check. C. Checksum. D. Echoplex. Organizations should consider which of the following first before connecting their LANs to the InternetA. WS locking mechanisms B. C. plan for providing the user with his account usage information D. Which x. DSL flavour delivers both downstream and upstream speeds of 1. Mbps over two copper twisted pairs A. HDSL B. SDSL C. ADSL D. VDSLAnswer A HDSL High Data Rate Digital Subscriber Line 1. Mbps each way over 2 copper twisted pair. Which of the following statements pertaining to Asynchronous Transfer Mode ATM is falseA. It can be used for voice B. It can be used for data C. It carries various sizes of packets D. It can be used for video. Answer C Asynchronous transfer mode ATM is a cell switching technology, as opposed to a packet switching technology like Frame Relay. ATM uses virtual circuits much like Frame Relay, but because it uses fixed size frames or cells, it can guarantee throughput. This makes ATM an excellent WAN technology for voice and video conferencing. Satellite communications are easily intercepted because A. How To Manage Hidden Updates On Skype'>How To Manage Hidden Updates On Skype. B. a satellite footprint is narrowly focused. C. a satellite footprint is very large. D. a satellite footprint does not change. Answer C I think it may have to do with the footprint of the satellite. Footprint The area of Earth with sufficient antenna gain to receive a signal from a satellite. Not A Granted Satellites transmit but they may not do it 2. Which one of the following protocols CANNOT be used for full duplex Wide Area Network WAN communications A. Synchronous Data Link Control SDLC B. Serial Line Internet Protocol SLIP C. Point to Point Protocol PPP D. High Level Data Link Control HDLCAnswer B By exclusion SLIP is the correct answer. Note Serial Line Internet Protocol SLIP is an older technology developed to support TCPIP communications over asynchronous serial connections, such as serial cables or modem dial up. SLIP is serial protocol opposed to WAN protocol. Not SDLC SDLC is full duplex. SDLC was developed to enable mainframes to communicate with remote locations. This is a WAN protocol. Not C. PPP is a full duplex protocol that provides bi directional links over synchronous, asynchronous, ISDN, frame relay and SONET connections. PPP is full duplex. Not D. HDLC is an extension of SDLC, which is mainly used in SNA environments. HDLC provides high throughput because it supports full duplex transmissions and is used in point to point and multipoint connections. PPP is full duplex. Fast ethernet operates at which of the following A. Mbps B. 1. Mbps C. Mbps D. All of the above. Answer B Fast Ethernet 1. Mbps IEE 8. 02. Which of the following statements about the Intranet is NOT trueA. It is an add on to a local area network. B. It is unrestricted and publicly available. C. It is usually restricted to a community of users D. MANS or WANSAnswer B An intranet is a private network that uses Internet technologies, such as TCPIP. The company has Web servers and client machines using Web browsers, and it uses the TCPIP protocol suite. The Web pages are written in Hypertext Markup Language HTML or Extensible Markup Language XML and are accessed via HTTP. Frame relay and X. A. Circuit switched services B. Cell switched services C. Packet switched services D. Dedicated digital services. Answer C Packet Switched Technologies X. Link Access Procedure Balanced LAPB Frame Relay Switched Multimegabit Data Service SMDS Asynchronous Transfer Mode ATM Voice over IP Vo. IPA Wide Area Network WAN may be privately operated for a specific user community, may support multiple communication protocols, or may provide network connectivity and services via A. Virtual Private Networks B. Virtual Private Networks C. BIOS segments extranets, intranets, and Virtual Private Networks D. Net. BIOS segments extranets, interest, and Virtual Private NetworksWhat is the proper term to refer to a single unit of Ethernet data A. Ethernet segment B. Ethernet datagram C. Ethernet frame D. Ethernet packet. Answer C When the Ethernet software receives a datagram from the Internet layer, it performs the following steps 1. Breaks IP layer data into smaller chunks if necessary which will be in the data field of ethernet frames. Which of the following is a LAN transmission protocolA. Ethernet B. Ring Topology C. Unicast D. Polling. Answer C Reference LAN Transmission Methods. LAN data is transmitted from the sender to one or more receiving stations using either a unicast, multicast, or broadcast transmission. Which of the following access methods is used by Ethernet A. CSMACD B. CSUDSU C. TCPIP D. FIFOAnswer A Under the Ethernet CSMACD media access process, any computer on a CSMACD LAN can access the network at any time. Which one of the following data transmission technologies is NOT packet switch based A. X. 2. 5 B. ATM Asynchronous Transfer Mode C. CSMACD Carrier Sense Multiple AccessCollision Detection D. Frame Relay. Answer B Examples of packet switching networks are X. Link Access Procedure Balanced LAPB, Frame Relay, Switched Multimegabit Data Systems SMDS, Asynchronous Transfer Mode ATM, and Voice over IP Vo. IP. Unshielded UTP does not require the fixed spacing between connections that is A. B. necessary with coaxial type connections C. D. necessary with fiber optic type connections. Answer B Fixed spacing between connections is referring to the fixed sized insulation that separates the inner wire from the shielding. What type of cable is used with 1. Base TX Fast EthernetA. Fiber optic cable B. Four pairs of Category 3, 4, or 5 unshielded twisted pair UTP wires. C. Two pairs of Category 5 unshielded twisted pair UTP or Category 1 shielded twisted pair STP wires D.
