Answer-12: Using managed DNS services ensures reliable and scalable domain name resolution.
Question-13. What are the benefits of using Content Delivery Networks (CDNs)?
Answer-13: CDNs reduce latency and offload traffic by caching content closer to users.
Question-14. What is the principle of least privilege in cloud networking?
Answer-14: Granting only the necessary network access to reduce security risks.
Question-15. How do you secure data in transit within a cloud network?
Answer-15: By using encryption protocols like TLS and IPsec.
Question-16. What is an Internet Gateway in AWS?
Answer-16: A gateway that allows communication between VPC and the internet.
Question-17. How do cloud providers support multi-region networking?
Answer-17: They provide global backbone networks and inter-region connectivity options.
Question-18. What is a peering connection in cloud networking?
Answer-18: It is a networking connection between two VPCs that allows routing traffic privately.
Question-19. How does network latency affect cloud applications?
Answer-19: High latency degrades application performance and user experience.
Question-20. What are best practices for IP address management in cloud?
Answer-20: Plan address ranges carefully, avoid overlaps, and use DHCP or static IPs appropriately.
Question-21. How do firewalls enhance cloud network security?
Answer-21: By filtering traffic based on rules to allow or deny access.
Question-22. What is the difference between stateful and stateless firewalls?
Answer-22: Stateful firewalls track connection states; stateless do not.
Question-23. How do you manage cloud network costs?
Answer-23: Optimize traffic flow, minimize data transfer, and use reserved network resources.
Question-24. What is a Bastion Host?
Answer-24: A server used to securely access instances in private networks.
Question-25. How can you automate cloud network management?
Answer-25: Using Infrastructure as Code (IaC) tools like Terraform or AWS CloudFormation.
Question-26. Why is regular network auditing important?
Answer-26: It ensures compliance and uncovers misconfigurations or vulnerabilities.
Question-27. What is the significance of DNSSEC in cloud DNS?
Answer-27: DNSSEC protects against DNS spoofing and cache poisoning attacks.
Question-28. How can Distributed Denial of Service (DDoS) attacks be mitigated in the cloud?
Answer-28: By using DDoS protection services and traffic filtering.
Question-29. What is a Cloud Router and when is it used?
Answer-29: A managed service to dynamically route traffic between on-premises and cloud networks.
Question-30. How does software-defined networking (SDN) benefit cloud deployments?
Answer-30: It enables flexible, programmable network management and automation.
Question-31. What are common network performance metrics to monitor?
Answer-31: Latency, packet loss, throughput, and jitter.
Question-32. How do private endpoints enhance security in cloud networking?
Answer-32: They allow secure access to cloud services without using public IP addresses.
Question-33. What is the role of service meshes in cloud networking?
Answer-33: Service meshes manage internal service-to-service communications securely and reliably.
Question-34. How does cloud networking handle IPv6?
Answer-34: Most providers support IPv6 for expanded address space and improved routing.
Question-35. What is an Endpoint Security Group?
Answer-35: It restricts inbound and outbound traffic at the endpoint level.
Question-36. How do you ensure high availability in cloud networks?
Answer-36: By using redundant paths, failover mechanisms, and load balancers.
Question-37. What is the function of a Transit Gateway?
Answer-37: It connects multiple VPCs and on-premises networks through a central hub.
Question-38. How is Quality of Service (QoS) applied in cloud networks?
Answer-38: QoS prioritizes critical traffic to maintain application performance.
Question-39. What are network service tiers in cloud?
Answer-39: They offer different performance and pricing levels for network traffic.
Question-40. How do you secure APIs in cloud networking?
Answer-40: By using API gateways, authentication, rate limiting, and encryption.
Question-41. What are common cloud network misconfigurations?
Answer-41: Open ports, overly permissive security groups, and unencrypted traffic.
Question-42. How can micro-segmentation improve cloud security?
Answer-42: It isolates workloads at a granular level to contain breaches.
Question-43. What role does cloud-native monitoring play in networking?
Answer-43: It provides real-time insights and automated alerts on network health.
Question-44. How do you manage hybrid cloud networking?
