it may be network layer or transport layer.. it depends on the design of the firewall.. also depends on the requirement specification..
layer 1, or the physical layer
A firewall generally works at layer 3 and 4 of the OSI model. Layer 3 is the Network Layer where IP works and Layer 4 is the Transport Layer, where TCP and UDP function. Many firewalls today have advanced up the OSI layers and can even understand Layer 7 - the Application Layer.
Data link layer
i believe (not quite sure) that it is at the application layer (layer 1)
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.
Application layer.
A web browser is best associated with the application layer of the OSI Model.
DHCP runs at the application layer of the OSI model.

Data link layer of the OSI model..
OSI stands for Open system interconnection model. Application layer is the seventh layer in OSI model.
False.
The subnet mask is associated with the Network layer of the OSI model, which is the third layer. This layer is responsible for routing packets of data across different networks and determining the best path for them. The subnet mask helps in identifying the network portion of an IP address, which is essential for routing decisions within and between networks.
