InOpTra Digital L2 Network Engineer Interview Questions and Answers

BGP and OSPF are both routing protocols, but BGP is used for inter-domain routing while OSPF is used for intra-domain routing.

• BGP is important in respect of OSPF because it allows for communication between different autonomous systems (AS)

• BGP is used to exchange routing information between different AS, while OSPF is used within a single AS

• BGP is used to determine the best path for traffic to take between different AS,...read more

BGP is used for routing between different autonomous systems, while IBGP is used for routing within the same autonomous system.

• BGP (Border Gateway Protocol) is an exterior gateway protocol used for routing between different autonomous systems.

• IBGP (Internal Border Gateway Protocol) is used for routing within the same autonomous system.

• BGP is used to exchange routing information between different autonomous systems (ASe...read more

No, SVIs cannot be created in L2 switches.

• SVI stands for Switched Virtual Interface.

• It is a virtual interface that represents a VLAN on a Layer 3 switch.

• L2 switches operate at Layer 2 of the OSI model and do not support routing or Layer 3 functionality.

• SVIs are used for routing between VLANs, which is a Layer 3 function.

• L2 switches can only create VLANs and assign ports to them for Layer 2 switching.

• To enable Layer 3 f...read more

The best link of OMP route depends on the specific needs and requirements of the network.

• Internet may be a better option for cost-effectiveness and flexibility, but MPLS may offer better reliability and security.

• Consider factors such as bandwidth, latency, traffic volume, and application requirements.

• Evaluate the pros and cons of each option before making a decision.

• For example, if the network requires low latency and ...read more

TLOC in Viptela SDWAN stands for Transport Locator and is used to identify the physical or virtual location of a device in the network.

• TLOC is a unique identifier assigned to each device in the SDWAN network.

• It helps in determining the optimal path for traffic routing.

• TLOCs can be based on various parameters such as interface, IP address, or VPN.

• They are used to define the connectivity between different sites in the ne...read more

I prefer not to disclose my current CTC. As for expected salary, I am open to negotiation based on the job requirements and market standards.

• I am looking for a fair compensation based on my skills and experience

• I am open to negotiation based on the job requirements and market standards

• I prefer not to disclose my current CTC

EIGRP Authentication is a security feature that ensures only authorized routers can participate in EIGRP routing.

• EIGRP Authentication uses a shared secret key between routers to authenticate each other.

• It can be configured in two modes - MD5 authentication and SHA authentication.

• MD5 authentication is more commonly used and provides better security.

• SHA authentication is newer and provides stronger security.

• EIGRP Authent...read more

OSPF DR and BDR are routers elected to manage communication within a multi-access network.

• DR stands for Designated Router and BDR stands for Backup Designated Router.

• They are elected by OSPF routers on a multi-access network to manage communication.

• DR and BDR are responsible for maintaining the topology database and forwarding updates to other routers.

• They reduce the amount of OSPF traffic on the network by acting as a...read more

VLAN stands for Virtual Local Area Network. It is a logical grouping of devices on a network based on their function, project or application.

• VLANs allow network administrators to segment a network into smaller, more manageable groups.

• Devices in a VLAN can communicate with each other as if they were on the same physical network, even if they are physically located on different switches.

• VLANs can improve network security...read more

A packet flows over the internet by being encapsulated in various network layers and routed through different devices.

• Packet is created at the application layer with data and destination IP address

• Packet is then encapsulated in a frame at the data link layer with source and destination MAC addresses

• Frame is transmitted over physical medium to the next hop based on routing table

• At each hop, the frame is decapsulated and...read more

BGP (Border Gateway Protocol) and OSPF (Open Shortest Path First) are routing protocols used in computer networks.

• BGP is an exterior gateway protocol used to exchange routing information between different autonomous systems.

• OSPF is an interior gateway protocol used to determine the best path for data packets within an autonomous system.

• BGP operates at the network layer and is commonly used in large-scale networks, such...read more

VLAN and VTP are both networking concepts, but they serve different purposes.

• VLAN (Virtual Local Area Network) is used to logically divide a single physical network into multiple virtual networks.

• VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used to manage VLAN configurations across a network of switches.

• VLANs provide segmentation, security, and broadcast control, while VTP simplifies VLAN management by ...read more
