SoftNet Microsystems Interview Questions and Answers

Yes, I am familiar with OSI model, MPLS links, etc.

• I have a strong understanding of the OSI model and its seven layers

• I am experienced in configuring and troubleshooting MPLS links

• I have worked with various networking protocols and technologies related to OSI and MPLS

Spanning Tree Protocol is a network protocol that ensures a loop-free topology in Ethernet networks.

• Prevents loops in Ethernet networks by blocking redundant paths

• Designated switches are elected as root bridge

• Uses Bridge Protocol Data Units (BPDUs) for communication

• Common variants include STP, RSTP, and MSTP

Routing protocol is a set of rules used by routers to determine the best path for data packets to reach their destination.

• Routing protocols help routers communicate with each other to share information about network topology.

• They determine the optimal path for data packets based on factors like network congestion, speed, and cost.

• Examples of routing protocols include RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and BGP (Border Gateway Protocol).

OSPF is a link-state routing protocol while BGP is a path vector routing protocol.

• OSPF is used within an autonomous system, while BGP is used between autonomous systems.

• OSPF calculates the shortest path based on link cost, while BGP selects the best path based on policies and attributes.

• OSPF uses Dijkstra's algorithm for route calculation, while BGP uses the path vector algorithm.

• OSPF is typically used in internal networks, while BGP is used for interconnecting different netw...read more

OSI (Open Systems Interconnection) model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven abstraction layers.

• OSI model divides network communication into seven layers

• Each layer has specific functions and interacts with adjacent layers

• Layers include physical, data link, network, transport, session, presentation, and application

• Example: Sending an email involves application layer for email client, transport layer fo...read more
