Comptia Network+ n10-008 exam Questions with 100% Correct Answers

OSI Correct Answer 7 - Application 6 - Presentation 5 - Session 4 - Transport 3 - Network 2 - Data Link 1 - Physical TCP/IP Correct Answer 4 - Application 3 - Transport 2 - Internet 1 - Network Interface Smart jack Correct Answer a type of network interface device that adds circuitry. This circuitry adds such features as converting between framing formats on a digital circuit (for example, a T1), supporting remote diagnostics, and regenerating a digital signal. Demarc/demarcation point/demarc extension Correct Answer this is the point in a telephone network where the maintenance responsibility passes from a telephone company to a subscriber (unless the subscriber purchased an inside wiring plan). This demarc is typically a box mounted to the outside of a customer's building (for example, a residence). This box is called a network interface device (NID). tip and ring Correct Answer The red and green wires found in an RJ-11 wall jacks, which carry voice, ringing voltage, and signaling information between an analog device (for example, a phone or a modem) and an RJ-11 wall jack. NT1 Correct Answer ISDN device that interconnects a 4-wire ISDN circuit with a 2-wire ISDN circuit. PPP Point-to-Point Protocol. Correct Answer Used to create remote access connections. very commonly used over dedicated leased lines HDLC (High-level Data Link Control) Correct Answer A bit-oriented synchronous data link layer protocol developed by the International Organization for Standardization (ISO). much less popular because it lacks the robust features of PPP ADSL (asymmetric digital subscriber line) Correct Answer One of many DSL technologies, is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream. used to provide high-speed WAN links DSL (digital subscriber line) Correct Answer A method of connecting to the Internet via a phone line. uses copper telephone lines but is able to relay data at much higher speeds than modems and does not interfere with telephone use. used to provide high-speed WAN links virtual PBX virtual private branch exchange Correct Answer Usually a VoIP telephony solution hosted by a service provider, which interconnects with a company's existing telephone system. virtual switch Correct Answer allows you to have Layer 2 control (for example, VLAN separation and filtering) for virtual servers co-resident on a single physical server hub-and-spoke Correct Answer enables you to minimize costs by not directly connecting any two locations a network design where we have a central device that is connected to multiple other devices mGRE Correct Answer is one of the key technologies in the Dynamic Multipoint VPN (DMVPN) solution. makes the tunnels that are formed dynamically between spokes and the hubs (and spokes to spokes) SAN (storage area network) Correct Answer You can construct a high-speed, highly reliable network for the express purpose of transmitting stored data. Metropolitan Area Network (MAN) Correct Answer More widespread than a CAN and less widespread than a WAN, a interconnects locations scattered throughout a the area SD-WAN - software-defined wide area network Correct Answer provides a simple policy and profile approach to managing the WAN. It also gives you tools to have new levels of visibility into and control over the use of the varied WAN circuits in the typical enterprise today T1 and T3 lines Correct Answer leased line Frame Relay Correct Answer packet-switch WAN ISDN (Integrated Services Digital Network) Correct Answer circuit switched
