Question 1 (8 points)

 

OSI Model has 7 layers as following:

7. Application Layer

6. Presentation Layer

5. Session Layer

4. Transport Layer

3. Network Layer

2. Data Link Layer

1. Physical Layer

Identify the corresponding layer of the OSI model each group of protocols belong to by filling in the number for the layer.

____ NFS, SAP, SQL

____ TCP, UDP

____ AES, CDR

____ DSL, ISDN,

____ IP, ICMP, OSPF, RIP

____ CSMA/CD, PPP, ARP, 802.x

____ DNS, FTP, LDAP, HTTP
