Post Exam Practice Flashcards
RDS
The Amazon Relational Database Service (RDS AWS) is a web service that makes it easier to set up, operate, and scale a relational database in the cloud. It provides cost-efficient, re-sizable capacity in an industry-standard relational database and manages common database administration tasks.
Direct Connect
AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. … AWS Direct Connect lets you establish a dedicated network connection between your network and one of the AWS Direct Connect locations.
AWS Artifact
AWS Artifact is a portal that provides an enterprise with access to security and compliance reports that apply to the Amazon Web Services (AWS) public cloud.
A user can download reports and other internal AWS documents via Artifact to ensure and demonstrate to auditors or regulators that the AWS offerings he or she uses meet security and compliance standards. These reports can also provide guidance to team members, such as developers, to ensure that they also adhere to these standards.

AWS NAT
NAT is a networking technique commonly used to give an entire private network access to the internet without assigning each host a public IPv4 address. The hosts can initiate connections to the internet and receive responses, but not receive inbound connections initiated from the internet.
When a host in the private network initiates an internet-bound connection, the NAT device’s public IP address becomes the source IP address for the outbound traffic. The response traffic from the internet therefore uses that public IP address as the destination IP address. The NAT device then routes the response to the host in the private network that initiated the connection.
AWS Storage Gateway
AWS Storage Gateway is a hybrid cloud storage service that gives you on-premises access to virtually unlimited cloud storage. … Your applications connect to the service through a virtual machine or hardware gateway appliance using standard storage protocols, such as NFS, SMB, and iSCSI.
AWS EFL
Amazon EFS (Elastic File System) is a cloud-based file storage service for applications and workloads that run in the Amazon Web Services (AWS) public cloud. AWS automatically deploys and manages the infrastructure for EFS, which is distributed across an unconstrained number of servers to avoid performance bottlenecks.
AWS Config
AWS Config is a service that enables you to assess, audit, and evaluate the configurations of your AWS resources. Config continuously monitors and records your AWS resource configurations and allows you to automate the evaluation of recorded configurations against desired configurations.

AWS Rekognition
AWS Rekognition is a service that lets developers working with Amazon Web Services add image analysis to their applications. With AWS Rekognition your apps can detect, remember and recognize objects, scenes, and faces in images.
Application Load Balancer
Application Load Balancers support content-based routing, and supports applications that run in containers. They support a pair of industry-standard protocols (WebSocket and HTTP/2) and also provide additional visibility into the health of the target instances and containers
Elastic Load Balancer
Elastic Load Balancing automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. It can handle the varying load of your application traffic in a single Availability Zone or across multiple Availability Zones.
What is difference between NAT instance and NAT gateway?
When a connection times out, a NAT gateway returns an RST packet to any resources behind the NAT gateway that attempt to continue the connection (it does not send a FIN packet). When a connection times out, a NAT instance sends a FIN packet to resources behind the NAT instance to close the connection.
