Suppose You Have Hired A Team Of Devops Freelancers To Set Up Your Infrastructure You Create An Iam Group Called Devops And Add The Team To That Group After The Team Finishes Setting Your Infrastructure Up They Leave Your Project What Actions Should You Take
You should delete only the user accounts from the developers, and keep the IAM group. It is possible that, in the future, you will want to hire more DevOps freelancers to change your infrastructure.
Keeping the IAM group will mean you kept the underlying set of policies, and therefore, future users can reuse those policies.
What Type Of Performance Can You Expect From Elastic Block Storage Service How Do You Back It Up And Enhance The Performance
The performance of elastic block storage varies, i.e., it can go above the SLA performance level and drop below it. SLA provides an average disk I/O rate which can, at times, frustrate performance experts who yearn for reliable and consistent disk throughput on a server. Virtual AWS instances do not behave this way. One can back up EBS volumes through a graphical user interface like elasticfox or the snapshot facility through an API call. Also, the performance can be improved by using Linux software raid and striping across four volumes.
What Is Amazon Dynamodb

Can We Disable Versioning On A Version
- No, we cannot disable versioning on a version-enabled bucket in Amazon S3. We can just suspend the versioning on a bucket in S3.
- Once we suspend versioning, Amazon S3 will stop creating new versions of the object. It just stores the object with null version ID.
- On overwriting an existing object, it just replaces the object with null version ID. So any existing versions of the object still remain in the bucket. But there will be no more new versions of the same object except for the null version ID object.

What Are The Best Practices You Would Follow While Creating Any Iam Policy
When granting permissions, we should follow the least privileged principle. We should avoid giving users or roles more permissions than they need to accomplish their tasks by following this principle. For example, if an employee needs only access to a specific EC2 instance, specify the instance in the IAM policy. Rather than granting an employee access to every instance in your AWS account.
Name And Explain Some Security Products And Features Available In Vpc
Here is a selection of security products and features:
- Security groups – This acts as a firewall for the EC2 instances, controlling inbound and outbound traffic at the instance level.

- Use AWS identity and access management to control access to your AWS resources
- Restrict access by allowing only trusted hosts or networks to access ports on your instance
- Review the rules in your security groups regularly
- Only open up permissions that you require
- Disable password-based login, for example, launched from your AMI
What Are The Best Practices You Will Follow While Creating Iam Users
We should always create individual IAM users for each person needing access to AWS services. Even if there are many employees who require the same access, we should create individual IAM users for all of them. This increases the security posture by providing every user of IAM a unique set of credentials.

What Is The Relation Between The Availability Zone And Region
An AWS Availability Zone is a physical location where an Amazon data center is located. On the other hand, an AWS Region is a collection or group of Availability Zones or Data Centers.
This setup helps your services to be more available as you can place your VMs in different data centers within an AWS Region. If one of the data centers fails in a Region, the client requests still get served from the other data centers located in the same Region. This arrangement, thus, helps your service to be available even if a Data Center goes down.

Effective Iam For Aws
Q2. What are the core elements of an AWS IAM policy statement and what is each elements purpose?
Principal: Identifies the principals that the statement applies to, most importantly and commonly an AWS IAM principal.
Effect: whether to Allow or Deny access if the statement applies Deny always wins when multiple statements apply.
Action: one or more AWS API actions the statement will Allow or Deny the Principal to invoke as a string or list of strings. Supports wildcards, ? and *.
Resource: one or more AWS resources the statement applies to, specified as ARNs. Supports wildcards, ? and *.
Q3. What identities can you specify in the Principal element?
The most important kind of identities are AWS IAM identities from within your AWS accounts: IAM roles & roles. You can also specify an entire AWS account, role sessions, and federated users.
The second most important kind of principal is an AWS service such as ec2, cloudtrail, or dynamodb.
Q4. What happens if you have one IAM statement that allows a principal to perform an operation on a resource and another statement that denies that same operation on the same resource?
The Deny effect always wins when multiple statements apply.
Q5. What are the basic differences between IAM roles and users? When should you use each?
You should prefer using IAM roles so that youre always using short term credentials. Using short term credentials minimizes risk of abuse if those credentials are leaked or stolen.
When You Need To Move Data Over Long Distances Using The Internet For Instance Across Countries Or Continents To Your Amazon S3 Bucket Which Method Or Service Will You Use
