Arco Lab Interview Questions and Answers

ISIS routing protocols are mostly used in service provider domain due to their scalability, fast convergence, and support for large networks.

• ISIS is preferred in service provider networks for its scalability, supporting larger networks compared to OSPF.

• ISIS has faster convergence times compared to OSPF, making it more suitable for service provider environments.

• ISIS supports multiple levels of hierarchy, allowing for better organization and management of large networks.

• ISIS is...read more

MOP preparation involves creating a Method of Procedure document for implementing changes in a system.

• MOP preparation involves documenting step-by-step instructions for carrying out a specific task or change in a system.

• It includes details such as prerequisites, actions to be taken, expected outcomes, and rollback procedures.

• MOPs are commonly used in IT and engineering fields to ensure changes are implemented correctly and efficiently.

• Examples of MOPs include network configur...read more

VPLS is used to create a virtual private network over a shared network infrastructure.

• VPLS allows multiple sites to communicate as if they are on the same LAN

• It provides a secure and private connection for data transmission

• VPLS is commonly used in enterprise networks to connect geographically dispersed locations

• It can support various types of traffic, including voice, video, and data

• VPLS uses MPLS technology to create the virtual network

VPLS is a Layer 2 service that connects multiple sites in a single bridged domain, while VPWS is a Layer 2 service that connects two sites directly.

• VPLS stands for Virtual Private LAN Service and connects multiple sites in a single bridged domain

• VPWS stands for Virtual Private Wire Service and connects two sites directly

• VPLS uses MAC learning to forward frames within the bridged domain

• VPWS provides point-to-point connectivity between two sites

• VPLS is more suitable for connect...read more

BGP stands for Border Gateway Protocol, used for routing between different autonomous systems.

• BGP is used to exchange routing information between different networks or autonomous systems.

• It helps in determining the best path for data packets to reach their destination.

• BGP is commonly used by Internet Service Providers (ISPs) to connect their networks.

• It is a key protocol for ensuring efficient and reliable routing on the internet.
