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.
The questions specifically asks "Which two layers of the OSI model do the TCP/IP protocols operate?"
Hence the correct answers would be (and from an OSI perspective):
Routers works in the network layer of the OSI model and choose the best ,shortest and optimized path to route the packets received from data link layer and requested by transport layer. BY Naghma
To be wan is to be faint or pale. An example sentence would be: She was so wan, it was starting to worry people.

WAN optimization is describes techniques that try to maximize data flow across a wide area network (WAN). WAN Optimization is important for improving access to critical applications and crucial information.
Which? Where are the Options?WAN Technologies operate & involve Layer1, Layer2 & Layer3 of OSI Model. Example of WAN Technology Protocols are Frame Relay, ATM & X.25 protocols.

WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
The X.25 standard specifies protocols at the Physical, Data Link, and Network Layers of the OSI Model.Broadband Cable functions at both the Physical, and Data Link Layers.ISDN functions at the Physical, Data Link, and Transport Layers.DSL, SONET, and T-Carriers function at the Physical Layer.Frame Relay, and ATM function at the Data Link Layer.

WAN generally means that there is a router involved, and thus IP routing is required to connect 2 end points. (OSI Layer 3 Network)LAN generally means that devices are directly connected to a switched network, where there is no router, and where MAC addresses are used to connect 2 end points. (OSI Layer 2 Network)However, originally, WAN referred to a physically wide area connection such as a T1 or Fibre Optic Ring, whereas LAN referred to computers connected within a short physical proximity.
ATM has (i) Fixed cell size, (ii) Implemented to meet the transport requirements for LAN,MAN and WAN applications, (iii) Connection-oriented, (iV) Cell size is fixed and is of 53 bytes 5 for header and 48 for payload, (V) Packet switching on private network that operate on data link layer on OSI. Whereas IP has (i) Variable cell size, (ii) Allow voice, data, fax and video signals to share a common networking infrastructure, (iii) Connection less, (iV) Cell size is upto 65535 bytes,and (V) Network addressing that operate on network layer on OSI frame relay.
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.
WAN. LAN is a short range connection, WAN is wide range.
