PPP has three main components: a way to encapsulate multiprotocol datagrams; a Link Control Protocol to establish, configure and test the data-link connection; and a group of network control protocols that establish and configure different types of network-layer protocols.
What are the three components of PPP?
PPP has three main components: a way to encapsulate multiprotocol datagrams; a Link Control Protocol to establish, configure and test the data-link connection; and a group of network control protocols that establish and configure different types of network-layer protocols.
How much total bandwidth is provided by a T1 line?
A T1 line can transmit data at a speed of 1.544 Mbps. Compared to standard telephone lines that used a modem to transfer voice and data at a mere 56 kbps, the T1 was an important step forward in delivering higher speed connections.
What is the advantage of using PPP on a serial link instead of HDLC?
Which is an advantage of using PPP on a serial link instead of HDLC? Authentication, multilink, and compression are options on PPP that are advantages over HDLC.What is a PPP frame?
PPP frames encapsulate packets of information that contain either configuration information or data.
What device forwards data and operates at layer three?
Router; A router is a device that knows how to forward data between independent networks and operates at layer three.
What is SLIP and PPP?
PPP replaces Serial Line Internet Protocol (SLIP) as the protocol of choice for point-to-point connections. PPP enables interoperability among the remote access software of different manufacturers. PPP also enables multiple network communication protocols to use the same physical communication line.
Which WAN technology can switch any type of payload based on labels?
MPLS is based on short path labels rather than IP network addresses. MPLS has several defining characteristics. It is multiprotocol, meaning it has the ability to carry any payload including IPv4, IPv6, Ethernet, ATM, DSL, and Frame Relay traffic. It uses labels that tell a router what to do with a packet.What are two common types of circuit switched WAN technologies?
The two most common types of circuit-switched WAN technologies are the public switched telephone network (PSTN) and the Integrated Services Digital Network (ISDN).
What is the recommended technology to use over a public WAN infrastructure when a branch office is connected to the corporate site?What is the recommended technology to use over a public WAN infrastructure when a branch office is connected to the corporate site? ISDN and ATM are Layer 1 and 2 technologies that are typically used on private WANs. Municipal WiFi is a wireless public WAN technology.
Article first time published onWhat are two reasons a company would use a VPN choose two?
What are two reasons a company would use a VPN? (Choose two.) Organizations use VPNs to have a reliable secure method to connect remote users, branch offices, and suppliers to the company network. To implement VPNs, a VPN gateway is necessary.
What is the protocol that provides ISPS the ability to send PPP frames over DSL networks?
PPPoE is implemented extensively by providers offering digital subscriber line (DSL) services. Providers that use PPPoE can connect multiple hosts on a single Ethernet local area network to a remote site via a common device such as a cable or DSL modem.
What is used by BGP to determine the best path to a destination?
If there are no specific settings that can affect the outcome, BGP Best Path Selection Algorithm determines the best route by selecting the shortest path to the destination. An Autonomous System is a single network or a set of networks and routers, which are under the control of one administrative entity.
What are the two components of PPP?
Key Concept PPP has two components: LCP that is responsible establishing, configuring, maintaining, and terminating the connection, and NCP which is specific to the Layer 3 protocol encapsulated by PPP.
Which of the following sub protocols are used by PPP?
PPP is designed to allow the simultaneous use of multiple network layer protocols, including IPv4 and v6, IPX, and AppleTalk. PPP operates using different network layer protocols (e.g., IPX and AppleTalk), whereas SLIP uses only TCP/IP-based IP.
What are the different fields in PPP frame?
PPP basically uses the same basic format as that of HDLC. PPP usually contains one additional field i.e. protocol field. This protocol field is present just after control field and before information or data field. PPP frame similar to HDLC frame, always begins and ends with standard HDLC flag.
What are the key elements of protocol?
A protocol is a set of rules that govern data communications. It defines what is communicated, how it is communicated, and when it is communicated. The key elements of a protocol are syntax, semantics, and timing.
What are PPP and SLIP most commonly used for?
Both SLIP and PPP are most common TCPIP modem protocols used for establishing dial-up internet connection. SLIP stands for Serial Line Internet protocol and PPP stands for Point-to-Point Protocol.
What is a TCP IP model?
TCP/IP Reference Model is a four-layered suite of communication protocols. … TCP stands for Transmission Control Protocol and IP stands for Internet Protocol. The four layers in the TCP/IP protocol suite are − Host-to- Network Layer −It is the lowest layer that is concerned with the physical transmission of data.
What is a layer three device?
Simply put, a layer 3 switch combines the functionality of a switch and a router. It acts as a switch to connect devices that are on the same subnet or virtual LAN at lightning speeds and has IP routing intelligence built into it to double up as a router.
Which of the following is Layer 3 device?
Joined:18/02/2011Points:633
Which of the following is a Layer 3 protocol?
The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks–hence, the name internet.
What is a characteristic of a WAN?
It connects multiple networks that are geographically separated. It spans across a campus or city to enable sharing of regional resources. It is typically owned and managed by a single home or business. It requires a wireless access point to connect users to the network.
Which two WAN infrastructure services are examples of private connections choose two *?
Private WANs can use T1/E1, T3/E3, PSTN, ISDN, Metro Ethernet, MPLS, Frame Relay, ATM, or VSAT technology.
What is a WAN Cisco quiz?
What is a WAN? a network infrastructure that provides access to other networks over a large geographic area. Refer to curriculum topic: 1.2.2. A WAN provides access to other networks over a large geographic area.
What are the three core components of the Cisco ACI Architecture?
- Application Network Profile (ANP) – Collection of end-point groups (EPG), their connections, and the policies that define those connections.
- Application Policy Infrastructure Controller (APIC) – The brains of the ACI architecture.
Which three pieces of information are identified by a URL choose three?
URLs typically consist of three pieces: The name of the protocol used to transfer the resource over the Web. The name of the machine hosting the resource. The name of the resource itself, given as a path.
Which two technologies are private WAN technologies choose two?
Private WAN technologies include leased lines, dialup, ISDN, Frame Relay, ATM, Ethernet WAN (an example is MetroE), MPLS, and VSAT.
Which three options are classified as Internet based WAN connectivity options choose three?
- Dark fiber. Connecting remote sites using dark fiber provides the greatest amount of flexibility and control. …
- MPLS. …

- Broadband. …
- Legacy T1.
What communication method is used in all WAN connections?
Communication medium used by WAN are PSTN or Satellite links. WAN operates on low data rates.
Which technology is required when switched?
Which technology is required when switched networks are designed to include redundant links? Spanning Tree Protocol (STP) is required when switched networks include redundant Layer 2 links.
