| Which level of the OSI model does full duplex mode of transmission get decided?
• [A] Application
• [B] Presentation
• [C] Session (your response)
• [D] Transport (correct answer)
Points possible: 1 Points earned: 0
ý think my responce was right.isn't it? | |

| Well according to the Lammle 2nd edition book you are right in choosing the session layer. Page 9 in the book 4th sentence down from the Bolded out Session Layer. | |

| thanks. What about clock rate command.Which command show clockrate.I tried sh int command but ý didn't saw.I amazing which command...(in router simulate not real router ) | |
|
| show run or show int s0 or s1 , and you should see the clockrate there | |

| Hmmm this may complicate the issue, I found this on ciscos website:

DECnet Media Access
DECnet Phase IV and DECnet/OSI support a variety of media-access implementations at the physical and data link layers. This has contributed to the relatively wide acceptance of DECnet in the computer networking industry. As explained in the following sections, both DECnet Phase IV and Phase V can support many of the common physical and data-link technologies in use today.
At the physical layer, DECnet Phase IV and DECnet/OSI support most of the popular physical implementations, including Ethernet/IEEE 802.3, Token Ring/IEEE 802.5, and Fiber Distributed Data Interface (FDDI). In addition, DECnet/OSI supports Frame Relay and X.21bis.
At the data link layer, DECnet Phase IV and DECnet/OSI support IEEE 802.2 Logical Link Control (LLC), Link Access Procedure, Balanced (LAPB), Frame Relay, and High-Level Data Link Control (HDLC). Both DECnet Phase IV and DECnet/OSI also support the proprietary Digital data-link protocol, Digital Data Communications Message Protocol (DDCMP), which provides point-to-point and multipoint connections; full-duplex or half-duplex communication over synchronous and asynchronous channels; and error correction, sequencing, and management.

AppleTalk Data Stream Protocol
The AppleTalk Data Stream Protocol (ADSP) is a session layer protocol in the AppleTalk protocol suite that establishes and maintains full-duplex communication between two AppleTalk sockets. ADSP guarantees that data is correctly sequenced and that packets are not duplicated. ADSP also implements a flow-control mechanism that allows a destination to slow source transmissions by reducing the size of the advertised receive window. ADSP runs directly on top of the DDP.

They all point to the SESSION LAYER | |

| On REAL router sh int s0 works, but on sim and exams you must type full sentence!
sh int s0
show interface serial0 | |

| So which is correct, accordint to me it is Transport layer too. |
