Networking in Cloud Environments Flashcards

CompTIA Cloud+ CV0-004 (V4) Flashcards

Front	Back
How are public and private subnets used in a VPC	Public subnets are used for resources with direct internet access, while private subnets are for resources without internet exposure.
How can latency impact cloud networking	High latency can slow down data transfer, negatively affecting application performance in cloud systems.
What are some common cloud networking protocols	Common protocols include HTTP/HTTPS, TCP/IP, FTP, and SNMP.
What are the key considerations for secure cloud networking	Secure cloud networking involves encryption, identity management, firewalls, and monitoring to protect data and resources.
What is a cloud API gateway	A cloud API gateway manages API traffic, security, and scalability for cloud applications.
What is a network ACL (Access Control List)	A network ACL is a layer of security that controls traffic to and from subnets at the packet level.
What is a Virtual Private Cloud (VPC) in cloud networking	A VPC is a logically isolated section of the cloud where you can launch resources in a virtual network.
What is an elastic IP address in cloud networks	An elastic IP is a static, public IP address you can allocate to cloud resources for consistent communication.
What is an IAM role in the context of networking	An IAM role grants temporary permissions to resources or users to perform specific actions within the cloud environment.
What is CIDR and how is it used in cloud networks	CIDR is a notation for describing IP address ranges and is used to allocate IP blocks in VPCs.
What is cloud peering	Cloud peering allows direct connectivity between different cloud networks or regions without using the public internet.
What is DHCP and its role in cloud networking	DHCP automatically assigns IP addresses and configuration details to devices in a cloud network.
What is Direct Connect in cloud networking	Direct Connect provides a dedicated physical connection between a data center and the cloud for higher performance and security.
What is DNS and how does it work in cloud environments	DNS translates domain names to IP addresses, enabling networked devices to communicate in cloud settings.
What is multi-region networking	Multi-region networking connects and synchronizes resources across multiple cloud regions for redundancy and accessibility.
What is serverless networking	Serverless networking automates the scaling and management of networking tasks typically required for server-based services.
What is the benefit of auto-scaling in cloud networks	Auto-scaling adjusts resource capacity automatically to meet traffic demand, optimizing performance and cost.
What is the difference between stateful and stateless firewalls	Stateful firewalls track the state of connections and remember past requests, while stateless firewalls evaluate each packet separately.
What is the OSI model and why is it essential in cloud networking	The OSI model is a framework for understanding network communication layers, ensuring compatibility between systems.
What is the purpose of NAT gateways in a VPC	NAT gateways enable private subnet resources to access the internet without exposing them directly.
What is the purpose of security groups in cloud networking	Security groups act as virtual firewalls that control inbound and outbound traffic for resources.
What is the role of a load balancer in cloud networking	A load balancer distributes incoming network traffic across multiple servers to ensure reliability and performance.
What is the role of a VPN in cloud networking	A VPN allows secure remote access to cloud resources by creating encrypted tunnels over the internet.
What is the role of TLS/SSL in secure cloud communication	TLS/SSL encrypt data in transit to protect it from unauthorized access or interception.
