A Review Of Validated CLF-C01 Latest Exam

On-demand EC2 instances are exactly that, on-demand. There are no upfront or termination fees, and you are charged for each second of usage (based on an hourly rate).

RDS offers the following SQL options: Aurora MySQL MariaDB PostreSQL Oracle Miscrosft SQLServer

EC2 instance have several different hard drive options. However, Elastic Block Store (EBS), which is a type of Network Attached Storage, is the most popular and widely used.

Identity and Access Management (IAM) is the AWS service where password policies and user credentials are managed. (Policy and Access Management as a service does not exist).

An Elastic Load Balancer is responsible for evenly distributing incoming web traffic between all the EC2 instances associated with it. This help prevent one server from becoming overloaded with traffic, while another server remains underutilized.

AWS Organizations is where you can manage multiple AWS accounts in one place (including it\'s billing features, such as consolidated billing).

Route 53 is AWS\'s domain and DNS management service. You can use it to register new domain names, as well as manage DNS record sets.

None

AWS services with built-in DDoS migigation/protection include: 1) Route 53 2) CloudFront 3) WAF (web application firewall) 4) Elastic Load Balancing 5) VPCs and Security Groups

Scaling is much faster and cost-effecting on the AWS cloud. With on-demand instances and autoscaling, future growth does not have to be predicted. More compute capacity can be added gradually
as demand increases.

CloudFront is a content caching service provided by AWS that utilizes "Edge Locations," which are AWS data centers located all around the world.

Simple Notification Service (SNS) is what publishes messages to SMS and/or email endpoints.

CloudFront allows you to cache content at edge locations. When a request is made for that content, the request is sent to an edge location (not your applications hardware), so the edge locations will absorb any DDoS attack and protect your underlining hardware.

S3 Standard Storage class has a rating of 99.999999999% durability (referred to as 11 nines) and 99.99% availability.

AWS has two main compute services, EC2 (server-based) and Lambda (serverless).

None

In SNS, there are two types of clients: publishers and subscribers. Publishers send the message, and subscribers receive the message.

None

You can easily share objects uploaded into S3 by provided others with the object\'s URL.

An AWS region is an isolated geographical area that is is comprised of three or more AWS Availability Zones.

DynamoDB is AWS\'s NoSQL database offering. NoSQL databases are for non-structured data that are typically stored in JSON-like, name-value documents.

DynamoDB does not use/support other NoSQL database engines. You only have access to use DynamoDB\'s built-in engine.

As part of AWS\' global infrastructure, Regions and Availability Zones allow for backups and duplicate components to be placed in seperate (isolated) areas of the globe. If one region/Availability Zone
were to fail, duplicates in other regions/Availability Zones can be used.

RDS offers SQL database options - otherwise known as relational databases.

Auto scaling is the feature that automated the process of adding/removing server capacity from a system (based on usage demand). Auto scaling creates a very cost effective system by never having too much or too little server capacity.
