Networking Protocols in Cloud Computing Questions and Answers for Viva

Answer-1: Networking protocols are standardized rules and conventions that govern data communication between devices in cloud environments.

Answer-2: They ensure reliable, secure, and efficient data transmission across distributed cloud infrastructure.

Answer-3: TCP/IP is the foundational suite of protocols enabling internet communication, ensuring data is sent and received accurately between cloud devices.

Answer-4: TCP is connection-oriented and reliable, while UDP is connectionless and faster but less reliable.

Answer-5: HTTP is the protocol used for transferring web pages and APIs, facilitating communication between clients and cloud servers.

Answer-6: HTTPS encrypts HTTP data using SSL/TLS for secure communication over cloud networks.

Answer-7: DNS translates human-readable domain names into IP addresses, allowing cloud resources to be easily accessed.

Answer-8: DHCP dynamically assigns IP addresses to cloud instances, simplifying network configuration.

Answer-9: IP addresses uniquely identify devices in the cloud, enabling proper routing and communication.

Answer-10: SSL/TLS protocols provide encryption and authentication to secure data in transit between cloud clients and servers.

Answer-11: FTP is used for transferring files between local systems and cloud storage or servers.

Answer-12: SMTP handles sending emails by routing messages between cloud email servers and clients.

Answer-13: SNMP monitors and manages cloud network devices by collecting and organizing information.

Answer-14: SSH provides secure remote command-line access to cloud instances for management and administration.

Answer-15: ICMP is used for sending error messages and operational information, such as ping requests, in cloud networks.

Answer-16: VPN protocols like IPsec and OpenVPN create encrypted tunnels to securely connect users to cloud resources.

Answer-17: BGP is used for routing data between different cloud data centers and external networks.

Answer-18: Load balancers distribute traffic using protocols like TCP, HTTP, and HTTPS to optimize cloud application performance.

Answer-19: A subnet divides a network into smaller segments, improving security and traffic management within cloud environments.

Answer-20: IPv4 uses 32-bit addresses with limited space, while IPv6 uses 128-bit addresses to support a larger number of devices.

Answer-21: NAT translates private IP addresses to public ones, allowing cloud instances to communicate externally while hiding internal IPs.

Answer-22: ARP maps IP addresses to MAC addresses, enabling communication within local cloud networks.

Answer-23: API Gateways manage, secure, and route API calls using protocols like HTTP/HTTPS in cloud services.

Answer-24: WebSocket enables full-duplex communication channels over a single TCP connection, ideal for real-time cloud applications.

Answer-25: MQTT is a lightweight messaging protocol used to connect IoT devices with cloud platforms efficiently.

Answer-26: REST uses HTTP methods to provide stateless, scalable communication between clients and cloud servers.

Answer-27: Multicast allows sending data to multiple recipients simultaneously, optimizing bandwidth in cloud networks.

Answer-28: FTPS adds SSL/TLS encryption to FTP, securing file transfers in cloud environments.

Answer-29: SMB enables shared access to files and printers across cloud networks.

Answer-30: Cloud networking uses layered protocol stacks like OSI or TCP/IP to organize communication functions.

Answer-31: HTTP/2 improves web performance in cloud apps by enabling multiplexing and header compression.

Answer-32: POP3 downloads emails from cloud servers to local clients for offline access.

Answer-33: IMAP allows synchronized email access across multiple devices with cloud-based email servers.

Answer-34: Firewalls filter traffic based on protocol rules to block unauthorized access to cloud resources.

Answer-35: SCTP provides reliable message-oriented communication, useful for telecommunication cloud services.

Answer-36: QUIC enhances transport layer security and reduces latency, improving cloud web service performance.

Answer-37: UDP is used in cloud services for applications like video streaming where speed is prioritized over reliability.

Answer-38: Telnet provides unencrypted remote access, mostly replaced by SSH due to security concerns.

Answer-39: LDAP queries and modifies directory services, supporting authentication and authorization in cloud.

Answer-40: ICMP tools like ping and traceroute help diagnose connectivity and latency issues in cloud networks.

Answer-41: SSL offloading improves performance by handling encryption/decryption at the load balancer instead of cloud servers.

Answer-42: Protocols enable secure, efficient communication and data transfer between on-premises and cloud resources.

Answer-43: SFTP provides secure file transfers using SSH encryption in cloud environments.

Answer-44: RESTful APIs use HTTP verbs like GET, POST, PUT, DELETE to perform operations on cloud resources.

Answer-45: ICMP redirects instruct hosts to use a different router for better network routing.

Answer-46: Protocols like HTTP/HTTPS and gRPC facilitate communication between cloud-based microservices.

Answer-47: DHCP relay forwards DHCP requests across different network segments in cloud environments.

Answer-48: Through adherence to open standards and use of protocol translation gateways.

Answer-49: Securing protocols prevents data interception, tampering, and unauthorized access in cloud networks.

Answer-50: Providers support multiple protocol versions to maintain compatibility while enabling new features.
