| 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. |
About the Flashcards
Flashcards for the CompTIA Cloud+ exam provide a focused review of cloud networking terminology, architectures, and core concepts. The deck covers VPCs and subnets, IP addressing (CIDR, DHCP, elastic IPs), DNS and common protocols, plus connectivity options such as VPN, Direct Connect, and cloud peering to reinforce exam vocabulary and system-level relationships.
Students can use the cards to drill security controls (security groups, network ACLs, IAM roles, TLS/SSL), traffic management (load balancers, NAT gateways), performance topics like latency and auto-scaling, and conceptual frameworks such as the OSI model and serverless networking. Focused prompts and concise answers make it easy to memorize definitions and understand how components interact under exam scenarios.
Topics covered in this flashcard deck:
- VPCs and subnets
- Security groups and NACLs
- IAM roles and TLS/SSL
- VPN, Direct Connect, peering
- CIDR, DHCP, DNS
- Load balancing and auto-scaling
