Q1) In the TCP/IP model, the best path through the network is determined at the ______________ layer. In the OSI model, the same function is carried out at the ______________ layer.
To find the answer to this question, let's first understand the TCP/IP and OSI models and the purpose of each layer.
The TCP/IP model is a conceptual framework used for network protocol design and communication. It is composed of four layers - Application, Transport, Internet, and Network Access. Each layer has its specific functions and protocols.
The OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a communication system into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
To determine the best path through the network, we need to consider the function of each layer in both models.
In the TCP/IP model, the layer responsible for determining the best path through the network is the Internet layer. This layer handles IP addressing, routing, and packet forwarding based on destination addresses. So, the answer options C and D can be eliminated.
In the OSI model, the layer responsible for the same function is the Network layer. The Network layer provides network addressing, routing, and traffic control. By considering this, we can eliminate answer options F as it does not match.
Based on the explanations above, the correct answer is A. In the TCP/IP model, the best path through the network is determined at the network access layer, whereas, in the OSI model, the same function is carried out at the network layer.
Q2) ______________ is a protocol that enables network devices to share a pool of IP addresses. This protocol operates at the ______________ layer of the OSI model.
To find the answer, let's understand the protocols and OSI layers involved.
The options provided are DNS, DHCP, and SMTP.
DNS (Domain Name System) is a protocol used for translating domain names into IP addresses. It operates at the application layer (Layer 7) of the OSI model. So, answer options A and B can be eliminated.
SMTP (Simple Mail Transfer Protocol) is a protocol used for sending emails between servers. It operates at the application layer (Layer 7) of the OSI model. So, answer options E and F can be eliminated.
DHCP (Dynamic Host Configuration Protocol) is a protocol used for dynamically assigning IP addresses to network devices. It enables devices to share a pool of IP addresses. DHCP operates at the network layer (Layer 3) of the OSI model.
Based on the explanations above, the correct answer is D. DHCP is a protocol that enables network devices to share a pool of IP addresses, and it operates at the network layer of the OSI model.
