Cloud Networking Foundations (CloudNetX CNX-001) Flashcards
CompTIA CloudNetX CNX-001 Flashcards
| Front | Back |
| How do cloud providers ensure high availability in networking | By utilizing redundant network paths and failover mechanisms. |
| How does a cloud CDN improve security | By providing protection against DDoS attacks and securing the origin server. |
| How does auto-scaling impact networking in the cloud | Auto-scaling adjusts network resources dynamically to match changes in workload demands. |
| Name a type of load balancing commonly used in cloud platforms | Application Load Balancers or Network Load Balancers. |
| Name one advantage of using virtual networks | Flexibility to scale and configure network environments. |
| What does an Elastic IP address provide in cloud networking | A static, public IP address that can be assigned to resources as needed. |
| What does latency mean in cloud networking | The delay in data transmission between two systems or networks. |
| What is a bastion host in cloud networking | A secure and controlled entry point for accessing virtual machines in a private network. |
| What is a Cloud VPN | A secure connection between on-premises networks and cloud resources over the internet. |
| What is a common protocol used for cloud routing | Border Gateway Protocol (BGP). |
| What is a Dedicated Cloud Interconnect | A private, high-bandwidth connection between on-premises networks and a cloud provider’s network. |
| What is a firewall in cloud networking | A security barrier that monitors and controls network traffic based on predefined rules. |
| What is a multi-region architecture in cloud networking | A design where resources and services are distributed across multiple geographic regions for availability and redundancy. |
| What is a network gateway in cloud networking | A gateway allows communication between different networks or subnets within and outside the cloud. |
| What is a service endpoint in cloud networking | A direct connection to a cloud service from a virtual network without the need for a public IP address. |
| What is a subnet | A smaller division within a virtual network that segments and organizes resources. |
| What is a virtual network | A logically isolated network within a cloud service provider's infrastructure. |
| What is a Virtual Private Cloud (VPC) | An isolated cloud resource environment built within a public cloud provider. |
| What is an IP whitelist in network security | A list of IP addresses allowed to access specific resources or services. |
| What is cloud load balancing | The distribution of incoming network traffic across multiple servers to ensure reliability and performance. |
| What is egress traffic in cloud networking | Data leaving a virtual network or cloud service to travel to an external network. |
| What is hybrid cloud networking | A networking approach that integrates on-premises infrastructure with public and private cloud resources. |
| What is ingress traffic in cloud networking | Data entering a virtual network or cloud service from an external source. |
| What is Network Address Translation (NAT) used for | To enable private IPs in a virtual network to communicate with external services without exposing private IP addresses. |
| What is peering in cloud networking | Establishing a direct network link between two virtual networks without the need for a public internet connection. |
| What is route propagation in a virtual network | The automatic update of routing tables based on changes in connected networks. |
| What is the benefit of using Content Delivery Networks (CDNs) | Faster content delivery by caching data in locations closer to users. |
| What is the difference between a private and a public IP address | A private IP is used within a virtual network, while a public IP is accessible over the internet. |
| What is the difference between stateful and stateless firewalls | Stateful firewalls track active connections, while stateless firewalls filter traffic based only on predefined rules. |
| What is the function of a DNS in cloud networking | To resolve domain names to IP addresses for easy resource access. |
| What is the principle of least privilege in network security | Granting only the necessary access to users or systems required for their functions. |
| What is the purpose of a network ACL | A network Access Control List provides stateless filtering of traffic to and from subnets based on rules. |
| What is the purpose of a virtual network interface (NIC) | To enable communication between a virtual machine and a network. |
| What is the purpose of routing in cloud networking | To direct data packets between different networks or subnets. |
| What is the purpose of Traffic Monitoring in cloud networking | To analyze and monitor data flow for performance and security optimization. |
| What is the role of a load balancer's health probe | To monitor and determine the availability or health of backend resources. |
| What is the role of a Network Security Group (NSG) | To control inbound and outbound traffic to cloud resources based on security rules. |
| What is the role of an API gateway in cloud networking | To manage and secure API traffic between services and users. |
| What is traffic encryption in cloud networking | The process of securing data in transit to protect it from being intercepted or tampered with. |
| Why is network security important in the cloud | To protect data and resources from unauthorized access and attacks. |
