Frame relay and PPP is used with WAN encapsulation.
Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember
that the word "frame" describes the data link layer protocol data unit (PDU), it will be
easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols,
Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.
What else can I help you with?
Which four are WAN data-link layer protocols?
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
Which statement accurately describes a role that is played in establishing a WAN connection?
Data link layer protocols like PPP and HDLC define how data is encapsulated for transmission across a WAN link.
Which layers of the OSI model does a WAN operate?
According to Cisco Curriculum Semester 4 1.2.1.1 As described in relation to the OSI reference model, WAN operations focus primarily on Layer 1 and Layer 2. WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
Router port that connects a wan link?
Data Terminal Eqipment (DTE)
Is ATM a WAN technology that functions in the Data Link layer?
Yes, True
Different types of WAN encapsulation?
Wide Area Network (WAN) encapsulation refers to the methods used to package and transmit data over long distances. Common types include Point-to-Point Protocol (PPP), which provides a standard method for encapsulating network layer protocols; Frame Relay, which offers a more efficient way to send data by using frames; and Multiprotocol Label Switching (MPLS), which directs data from one node to the next based on short path labels rather than long network addresses. Each encapsulation method has its own advantages and is suited for different network requirements and performance needs.
Can several lans be part of a wan connected by dsl?
Yes it could
Which device encodes data for transmission across the WAN service provider transmission link?
DCE
What do WAN Data link protocols describe?
Here's what you should know: Data link layer protocols must be concerned with the rules for transmitting data across the network media, particularly with encoding and carrying "frames" of data. Although this layer includes providing error detection and notification by adding the Cyclic Redundancy Check (CRC), the Transport Layer is primarily responsible for end-to-end error-free message delivery. WAN Data-Link protocols primarily define how data frames should be packaged for different types of networks. To quote: The data link protocols available for WAN communications define how networks will carry the data frames on a given data link. The data link protocols used for WANs come in three categories: 1. Interface to IBM enterprise data centers: SDLC 2. WAN connections using peer devices: HDLC & PPP 3. Switched or relayed services: X.25/LAPB, Frame Relay, ISDN/LAPD, ATM. Some of these protocols provide functionality as high as in the Network layer of the OSI, and all of these protocols transfer data over a WAN data link.
