IP Interview questions Flashcards
Explain the concept of TCP/IP?
TCP/IP helps connect devices over the Internet and to transmit data from one device to another.” Primary purpose is to deliver packets
How many layers does TCP/IP architecture have?
4 Layers (NITA) Network, Internet, Transport, Application. New model has Network combined with physical and Data Link
What is a IP datagram?
Datagram allows IP to recognize the format of data. Includes header and footer information.
How does IP protect data on the network?
IP encrypts data going across the network and provides security and authentication
How can we measure performance of an IP link?
Through network monitoring and looking at logs
What is the difference between flow control and error control?
Flow control maintains proper transmission from sender to receiver and prevents data loss. Error control ensures the delivery of error-free data from sender to receiver detects and corrects errors.
What is a socket?
Primary purpose is to identify the network server’s unique IP address and the port number
What is the function of a router?
Router is a networking devices used to forward packets between computers and direct traffic.
What is the difference between OSI and TCP/IP?
OSI is a framework describing the functions of a network and TCP/IP is a protocol suite that allows devices to connect over the internet. OSI is connection oriented and TCP/IP is connectionless.
What are the advantages of using TCP/IP?
TCP/IP model supports a variety of applications, protocols, and devices that can communicate over the internet. TCP/IP model is also more adaptable and scalable, as it can handle different network architectures, topologies, and technologies.
What are some of the common problems with TCP/IP?
Routing and security. Cannot communicate with a host on the network
What is a VLAN?
A VLAN is a logical group of networking devices linked to defined ports on a switch. Enables two VLANs to communicate without a router.
What are the advantages of a VLAN?
Reduces broadcast traffic and provides an additional layer of security.
What are the different types of VLAN memberships?
Static VLAN (port based) and Dynamic VLAN (dynamically assigned based on IP address.
What is the range of VLAN?
The range of VLAN is 0–4096, with 0 being the first VLAN and 4096 being the last VLAN. Cannot use both the first and the last VLANs. 1 is the default VLAN, or the management VLAN
