Viasat Technical Lead Interview Questions and Answers

Routing process involves determining the optimal path for data packets to travel from source to destination.

• Routing is the process of selecting the best path for data packets to reach their destination.

• It involves analyzing network topology, traffic conditions, and routing protocols.

• Routing algorithms determine the most efficient path based on factors like hop count, bandwidth, latency, and cost.

• Routing tables are used...read more

Static route is a pre-configured path for network traffic to reach a specific destination.

• Static routes are manually configured by a network administrator.

• They are used to define a specific path for network traffic to follow.

• Static routes are commonly used in small networks with few routers.

• They are less flexible than dynamic routing protocols.

• Example: ip route 192.168.1.0 255.255.255.0 10.0.0.1

MPLS ping is a tool used to test connectivity between two MPLS-enabled devices by sending ICMP echo requests.

• MPLS ping works by encapsulating ICMP echo requests within MPLS packets.

• It uses the MPLS label stack to route the packets through the network.

• The receiving device responds with an ICMP echo reply, allowing the sender to verify connectivity.

• MPLS ping is commonly used for troubleshooting MPLS networks and verifyin

MPLS is required for efficient and reliable data packet forwarding in complex networks.

• MPLS allows for traffic engineering, prioritization, and quality of service in networks.

• It provides better performance and reliability compared to traditional IP routing.

• MPLS is essential for connecting multiple locations in a secure and efficient manner.

• It simplifies network management and troubleshooting by creating virtual paths f

SAP is a software company that provides enterprise resource planning (ERP) solutions for businesses.

• SAP stands for Systems, Applications, and Products in Data Processing

• SAP offers a wide range of software solutions for various business functions such as finance, HR, supply chain management, etc.

• SAP ERP system integrates different business processes and functions to streamline operations and improve efficiency

Jira System design involves creating workflows, issue types, custom fields, and permissions to optimize project management.

• Design workflows to track the progress of tasks from start to finish

• Create custom issue types to categorize different types of work

• Define custom fields to capture specific information for each issue

• Set up permissions to control who can view, edit, and transition issues

• Integrate Jira with other tool...read more

Networking devices are hardware devices that facilitate communication and data transfer between different devices in a network.

• Networking devices include routers, switches, hubs, modems, and firewalls.

• Routers are used to connect multiple networks together and direct traffic between them.

• Switches are used to connect devices within a network and direct traffic between them.

• Hubs are used to connect multiple devices within...read more

Routing protocols are used to determine the best path for data to travel between networks.

• There are two types of routing protocols: distance-vector and link-state.

• Distance-vector protocols are simpler but less efficient than link-state protocols.

• Examples of distance-vector protocols include RIP and IGRP.

• Examples of link-state protocols include OSPF and IS-IS.

• Routing protocols have different metrics to determine the bes...read more
