I applied via Company Website and was interviewed before Nov 2020. There was 1 interview round.
A network is a group of interconnected devices that communicate with each other to share resources and information.
Networks can be wired or wireless
They can be local (LAN) or wide area (WAN)
They use protocols such as TCP/IP to facilitate communication
Examples include the internet, corporate networks, and home networks
The basic steps of network troubleshooting involve identifying the problem, gathering information, isolating the issue, testing solutions, and implementing fixes.
Identify the problem by gathering information from the user or monitoring tools
Isolate the issue by checking connectivity, configurations, and logs
Test potential solutions by implementing changes or using diagnostic tools
Implement fixes by applying changes to ...
VLAN stands for Virtual Local Area Network. It is a logical grouping of devices on a network based on function, project, or application.
VLANs allow network administrators to segment a network into smaller, more manageable groups.
Each VLAN is a separate broadcast domain, which means that broadcasts sent by a device in one VLAN are not seen by devices in other VLANs.
There are two types of VLANs: port-based VLANs and tag-...
STP stands for Spanning Tree Protocol. Port Fast is a feature in STP that allows a port to bypass the listening and learning states.
STP is a protocol used to prevent loops in a network by blocking redundant paths
It works by electing a root bridge and calculating the shortest path to it
Port Fast is a feature that allows a port to immediately transition to forwarding state, bypassing the listening and learning states
It i...
OSPF is a routing protocol used in IP networks to distribute IP routing information.
OSPF stands for Open Shortest Path First
It is a link-state routing protocol
OSPF packets include Hello, Database Description, Link State Request, Link State Update, and Link State Acknowledgement
Hello packets are used to establish and maintain neighbor relationships
Database Description packets are used to exchange information about the c...
A router is a networking device that forwards data packets between computer networks.
Routers operate at the network layer of the OSI model.
They use routing tables to determine the best path for data to travel.
Routers can connect different types of networks, such as LANs and WANs.
Examples of routers include Cisco, Juniper, and TP-Link.
Routers can provide security features such as firewalls and VPNs.
L2 switches operate at the data link layer and L3 switches operate at the network layer.
L2 switches forward traffic based on MAC addresses while L3 switches forward traffic based on IP addresses.
L2 switches are simpler and less expensive than L3 switches.
L3 switches can perform routing functions and support multiple VLANs while L2 switches cannot.
L3 switches are used in larger networks where routing and VLANs are neces...
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
Firewall acts as a barrier between a trusted internal network and an untrusted external network.
It filters network traffic based on IP addresses, ports, protocols, and other criteria.
Firewalls can be hardware-based or software-based.
They can be configured to allow or block speci...
Policy is a set of rules or guidelines that dictate how a network should be managed and used.
Identify the purpose of the policy
Define the scope of the policy
Determine the target audience
Create the policy document
Communicate the policy to all stakeholders
Enforce the policy and regularly review and update it

It offers zero trust network access, secure web gateway, firewall as a service, and more.
Implementation involves setting up policies, configuring connectors, and monitoring traffic.
Example: Configuring user authentication methods, defin...
IPsec and GRE tunnels can be used to securely migrate from existing network to SASE architecture.
IPsec tunnels can provide secure communication between on-premises network and SASE architecture by encrypting traffic.
GRE tunnels can be used to encapsulate and transport traffic between different network environments during migration.
Both IPsec and GRE tunnels can help ensure data confidentiality and integrity during the ...
IPsec provides secure communication over the internet, while GRE is a tunneling protocol for encapsulating various network layer protocols.
IPsec is a suite of protocols used to secure internet protocol (IP) communications by authenticating and encrypting each IP packet.
GRE is a tunneling protocol that encapsulates a wide variety of network layer protocols inside virtual point-to-point links.
IPsec can be used to create ...
