Hexaware Technologies Network Engineer Interview Questions and Answers

Q1. What is DNS please explain
Ans. 
DNS stands for Domain Name System, which translates domain names to IP addresses.
• DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to IP addresses (like 172.217.3.206).

• It helps users access websites by typing in easy-to-remember domain names instead of complex IP addresses.

• DNS servers store records of domain names and their corresponding IP addresses, allowing for effi...read more

Q2. What is DHCP please explain
Ans. 
DHCP stands for Dynamic Host Configuration Protocol, used to automatically assign IP addresses to devices on a network.
• DHCP eliminates the need for manual IP address configuration on each device

• It assigns IP addresses dynamically, allowing for efficient use of available addresses

• DHCP servers lease IP addresses to devices for a specific period of time

• DHCP also provides other network configuration information, such as su...read more

Q1. Tell about the SDWAN concept.
Ans. 
SDWAN is a software-defined approach to managing and optimizing WAN connections.
• SDWAN uses software to control and manage network traffic across multiple WAN connections.

• It can dynamically route traffic based on network conditions and application requirements.

• SDWAN can improve network performance, reduce costs, and simplify network management.

• Examples of SDWAN vendors include Cisco, VMware, and Silver Peak.

Q2. Difference between OSPF & EIGRP
Ans. 
OSPF is a link-state protocol while EIGRP is a hybrid protocol.
• OSPF uses Dijkstra's algorithm to calculate the shortest path while EIGRP uses a metric based on bandwidth, delay, reliability, load, and MTU.

• OSPF supports VLSM and route summarization while EIGRP supports only route summarization.

• OSPF is an open standard protocol while EIGRP is a Cisco proprietary protocol.

• OSPF has a higher convergence time than EIGRP.

• OSPF...read more

Q3. What is the cost of the default route?
Ans. 
The cost of default route varies depending on the network infrastructure and service provider.
• The cost of default route is usually included in the overall cost of the internet service provided by the ISP.

• The cost may also depend on the type of connection, such as fiber optic or cable.

• In some cases, the cost may be higher for businesses that require more bandwidth and faster speeds.

• The cost may also vary depending on th...read more

Q4. How OSPF neighbourship occuures?
Ans. 
OSPF neighbourship occurs when two OSPF routers establish a relationship to exchange routing information.
• OSPF routers send hello packets to discover neighbours

• If the hello packets are compatible, the routers become neighbours

• The routers exchange database descriptors to synchronize their link-state databases

• If the databases are the same, the routers become fully adjacent

• Neighbourship can be affected by network topology

Q5. What is AS path prepend?
Ans. 
AS path prepend is a technique used in BGP to influence the path selection of traffic.
• AS path prepend involves adding the same AS number multiple times to the AS path attribute of a BGP route advertisement.

• This makes the path appear longer and less desirable, causing traffic to prefer other paths.

• AS path prepend can be used to influence inbound or outbound traffic.

• Inbound traffic can be influenced by adding the local A...read more

Q6. What is the difference between overlay and underlay?
Ans. 
Overlay is a network virtualization technique that adds a layer of abstraction over the physical network, while underlay refers to the physical network infrastructure.
• Overlay is used to create virtual networks on top of the physical network infrastructure.

• Underlay refers to the physical network infrastructure that provides connectivity between devices.

• Overlay networks are used to provide network virtualization, multi-t...read more

Q7. What is VRF and how it works?
Ans. 
VRF stands for Virtual Routing and Forwarding. It is a technology that allows multiple instances of a routing table to coexist on the same router.
• VRF provides logical separation of routing tables, allowing multiple routing domains to exist on a single physical router.

• Each VRF has its own routing table and forwarding table, which allows for overlapping IP addresses to be used without conflict.

• VRFs are commonly used in M...read more

Q8. What is BGP damping?
Ans. 
BGP damping is a technique used to reduce the impact of unstable routes on the internet.
• BGP damping helps to prevent the propagation of unstable routes by temporarily suppressing them.

• It is used to reduce the impact of route flapping, which occurs when a route repeatedly alternates between available and unavailable states.

• BGP damping assigns a penalty value to unstable routes, and if the penalty exceeds a certain thres...read more
