A. Create a lifecycle rule to transition the documents from the STANDARD storage class to the GLACIER storage class after 15 days.
B. Create a lifecycle rule to transition the documents from the STANDARD storage class to the STANDARD_IA storage class after 15 days, and then to the GLACIER storage class after an additional

質問 # 375
You need to set up a complex network infrastructure for your organization that will be reasonably easy to deploy, replicate, control, and track changes on. Which AWS service would be best to use to help you accomplish this?
A. Amazon Route 53
B. AWS Import/Export
C. AWS CloudFormation
D. Amazon CloudWatch
正解：C
解説：
AWS CloudFormation is a service that helps you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. You create a template that describes all the AWS resources that you want (like Amazon
EC2 instances or Amazon RDS DB instances), and AWS CloudFormation takes care of provisioning and configuring those resources for you. You don't need to individually create and configure AWS resources and figure out what's dependent on what. AWS CloudFormation handles all of that.

A company runs a stateless web application in production on a group of Amazon EC2 On-Demand Instances behind an Application Load Balancer. The application experiences heavy usage during an 8-hour period each business day. Application usage is moderate and steady overnight Application usage is low during weekends.
The company wants to minimize its EC2 costs without affecting the availability of the application.
Which solution will meet these requirements?
A. Use Reserved instances for the baseline level of usage Use Spot Instances for any additional capacity that the application needs.
B. Use Spot Instances for the entire workload.
C. Use On-Demand Instances for the baseline level of usage. Use Spot Instances for any additional capacity that the application needs
D. Use Dedicated Instances for the baseline level of usage. Use On-Demand Instances for any additional capacity that the application needs
正解：A
質問 # 377
An enterprise wants to use a third-party SaaS application. The SaaS application needs to have access to issue several API commands to discover Amazon EC2 resources running within the enterprise's account The enterprise has internal security policies that require any outside access to their environment must conform to the principles of least privilege and there must be controls in place to ensure that the credentials used by the SaaS vendor cannot be used by any other third party.
Which of the following would meet all of these conditions?
A. Create an IAM role for cross-account access allows the SaaS provider's account to assume the role and assign it a policy that allows only the actions required by the SaaS application.
B. Create an IAM user within the enterprise account assign a user policy to the IAM user that allows only the actions required by the SaaS application create a new access and secret key for the user and provide these credentials to the SaaS provider.
C. Create an IAM role for EC2 instances, assign it a policy that allows only the actions required tor the SaaS application to work, provide the role ARN to the SaaS provider to use when launching their application instances.
D. From the AWS Management Console, navigate to the Security Credentials page and retrieve the access and secret key for your account.

Explanation:
Granting Cross-account Permission to objects It Does Not Own
In this example scenario, you own a bucket and you have enabled other AWS accounts to upload objects.
That is, your bucket can have objects that other AWS accounts own.
Now, suppose as a bucket owner, you need to grant cross-account permission on objects, regardless of who the owner is, to a user in another account. For example, that user could be a billing application that needs to access object metadata. There are two core issues:
The bucket owner has no permissions on those objects created by other AWS accounts. So for the bucket owner to grant permissions on objects it does not own, the object owner, the AWS account that created the objects, must first grant permission to the bucket owner. The bucket owner can then delegate those permissions.
Bucket owner account can delegate permissions to users in its own account but it cannot delegate permissions to other AWS accounts, because cross-account delegation is not supported.
In this scenario, the bucket owner can create an AWS Identity and Access Management (IAM) role with permission to access objects, and grant another AWS account permission to assume the role temporarily enabling it to access objects in the bucket.
Background: Cross-Account Permissions and Using IAM Roles
IAM roles enable several scenarios to delegate access to your resources, and cross-account access is one of the key scenarios. In this example, the bucket owner, Account A, uses an IAM role to temporarily delegate object access cross-account to users in another AWS account, Account C.
Each IAM role you create has two policies attached to it:
A trust policy identifying another AWS account that can assume the role.
An access policy defining what permissions-for example, s3:GetObject-are allowed when someone assumes the role. For a list of permissions you can specify in a policy, see Specifying Permissions in a Policy.
The AWS account identified in the trust policy then grants its user permission to assume the role. The user can then do the following to access objects:
Assume the role and, in response, get temporary security credentials.
Using the temporary security credentials, access the objects in the bucket.
For more information about IAM roles, go to Roles (Delegation and Federation) in IAM User Guide.
The following is a summary of the walkthrough steps:
Account A administrator user attaches a bucket policy granting Account B conditional permission to upload objects.
Account A administrator creates an IAM role, establishing trust with Account C, so users in that account can access Account A.
The access policy attached to the role limits what user in Account C can do when the user accesses Account A.
Account B administrator uploads an object to the bucket owned by Account A, granting full-control permission to the bucket owner.
Account C administrator creates a user and attaches a user policy that allows the user to assume the role.
User in Account C first assumes the role, which returns the user temporary security credentials. Using those temporary credentials, the user then accesses objects in the bucket.
For this example, you need three accounts. The following table shows how we refer to these accounts and the administrator users in these accounts. Per IAM guidelines (see About Using an Administrator User to Create Resources and Grant Permissions) we do not use the account root credentials in this walkthrough.
Instead, you create an administrator user in each account and use those credentials in creating resources and granting them permissions
