Q

AWS support plan:

A

In addition, customers with a Business or Enterprise support plan have access to these features:

  • Use-case guidance: what AWS products, features, and services to use to best support your specific needs.
  • AWS Trusted Advisor, which inspects customer environments. Then, Trusted Advisor identifies opportunities to save money, close security gaps, and improve system reliability and performance.
  • An API for interacting with Support Center and Trusted Advisor. This API allows for automated support case management and Trusted Advisor operations.
  • Third-party software support: help with Amazon Elastic Compute Cloud (EC2) instance operating systems and configuration. Also, help with the performance of the most popular third-party software components on AWS.

The AWS Support API provides access to some of the features of the AWS Support Center. This API allows programmatic access to AWS Support Center features to create, manage, and close your support cases, and operationally manage your Trusted Advisor check requests and status. AWS provides this access for AWS Support customers who have a Business or Enterprise support plan. Since the Business support plan is more affordable than the Enterprise, therefore, the most cost-effective support plan to use is Business.

216

Q

Among the following services, which is the most suitable one to use to store the results of I/O-intensive SQL database queries to improve application performance?

A

Amazon ElastiCache offers fully managed Redis and Memcached. Seamlessly deploy, run, and scale popular open source compatible in-memory data stores. With this service, you can build data-intensive apps or improve the performance of your existing apps by retrieving data from high throughput and low latency in-memory data stores.

The in-memory caching provided by Amazon ElastiCache can be used to significantly improve latency and throughput for many read-heavy application workloads (such as social networking, gaming, media sharing and Q&A portals) or compute-intensive workloads (such as a recommendation engine).

In-memory caching improves application performance by storing critical pieces of data in memory for low-latency access. Cached information may include the results of I/O-intensive database queries or the results of computationally-intensive calculations.

Hence, the correct answer in this scenario is: Amazon ElastiCache.

221
Q

AWS OptsWorks

A

AWS OpsWorks is a configuration management service that helps customers configure and operate applications, both on-premises and in the AWS Cloud, using Chef and Puppet.

222
Q

AWS Identity and Access Management (IAM)

A

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources. IAM has various identities such as IAM Users, IAM Groups, and IAM Roles.

An IAM group is a collection of IAM users. Groups let you specify permissions for multiple users, which can make it easier to manage the permissions for those users. For example, you could have a group called Admins and give that group the types of permissions that administrators typically need. Any user in that group automatically has the permissions that are assigned to the group. If a new user joins your organization and needs administrator privileges, you can assign the appropriate permissions by adding the user to that group. Similarly, if a person changes jobs in your organization, instead of editing that user’s permissions, you can remove him or her from the old groups and add him or her to the appropriate new groups.

227
Q

There is an incident with your team where an S3 object was deleted using an account without the owner’s knowledge. What can be done to prevent unauthorized deletion of your S3 objects?

A

By setting up MFA, you add an extra layer of protection for your AWS accounts. This is very useful for preventing unwanted access to your AWS resources. In S3, once versioning is enabled for your objects, you can also set up MFA delete so that deleting objects require an additional MFA authentication.

MFA delete can help prevent accidental bucket deletions by requiring the user who initiates the delete action to prove physical possession of an MFA device with an MFA code and adding an extra layer of friction and security to the delete action. Remember that only the bucket owner (root account) can enable MFA delete.

Hence, the correct answer is: Configure MFA delete on the S3 bucket.

228
Q

A

Some key design principles of the AWS Cloud include

scalability, 
disposable resources, 
automation, 
loose coupling managed services instead of servers,

229
Q

Instance metadata

A

Instance metadata is data about your instance that you can use to configure or manage the running instance. Instance metadata is divided into categories, for example, host name, events, and security groups.

You can also use instance metadata to access user data that you specified when launching your instance. For example, you can specify parameters for configuring your instance, or include a simple script. You can build generic AMIs and use user data to modify the configuration files supplied at launch time. For example, if you run web servers for various small businesses, they can all use the same generic AMI and retrieve their content from the Amazon S3 bucket that you specify in the user data at launch. To add a new customer at any time, create a bucket for the customer, add their content, and launch your AMI with the unique bucket name provided to your code in the user data. If you launch more than one instance at the same time, the user data is available to all instances in that reservation. Each instance that is part of the same reservation has a unique ami-launch-index number, allowing you to write code that controls what to do. For example, the first host might elect itself as the original node in a cluster. For a detailed AMI launch example, see Example: AMI launch index value.

Q

Agility

A

The cloud allows you to innovate faster because you can focus your valuable IT resources on developing applications that differentiate your business and transform customer experiences rather than managing infrastructure and data centers. With cloud, you can quickly spin up resources as you need them, deploying hundreds or even thousands of servers in minutes. The cloud also makes it easy and fast to access a broad range of technology such as compute, storage, databases, analytics, machine learning, and many other services on an as-needed basis. As a result, you can very quickly develop and roll out new applications, and your teams can experiment and innovate more quickly and frequently. If an experiment fails, you can always de-provision resources without risk.

232
Q

Lambda@Edge

A

Lambda@Edge is a feature of Amazon CloudFront that lets you run code closer to users of your application, which improves performance and reduces latency. With Lambda@Edge, you don’t have to provision or manage infrastructure in multiple locations around the world. You pay only for the compute time you consume - there is no charge when your code is not running.

Policies and permissions in IAM
PDF
Kindle
RSS
You manage access in AWS by creating policies and attaching them to IAM identities (users, groups of users, or roles) or AWS resources. A policy is an object in AWS that, when associated with an identity or resource, defines their permissions. AWS evaluates these policies when an IAM principal (user or role) makes a request. Permissions in the policies determine whether the request is allowed or denied. Most policies are stored in AWS as JSON documents. AWS supports six types of policies: identity-based policies, resource-based policies, permissions boundaries, Organizations SCPs, ACLs, and session policies.

IAM policies define permissions for an action regardless of the method that you use to perform the operation. For example, if a policy allows the GetUser action, then a user with that policy can get user information from the AWS Management Console

234
Q

AWS cognito

A

Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Apple, Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0 and OpenID Connect.

235
Q

AWS Config

A

AWS Config continuously evaluates your resources as they are created, changed, or deleted.

AWS Config is a service thatenables 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.

236
Q

Where can you back up Amazon EBS volumes?

A

You can back up the data on your Amazon EBS volumes to Amazon S3 by taking point-in-time snapshots. Snapshots are incremental backups, which means that only the blocks on the device that have changed after your most recent snapshot are saved. This minimizes the time required to create the snapshot and saves on storage costs by not duplicating data. Each snapshot contains all of the information that is needed to restore your data (from the moment when the snapshot was taken) to a new EBS volume.

237
Q

Well-Architected Framework pillars

A

The Well-Architected Framework has been developed to help cloud architects build secure, high-performing, resilient, and efficient infrastructure for their applications. This is based on five pillars namely:

  1. Operational Excellence
  2. Security
  3. Reliability
  4. Performance Efficiency
  5. Cost Optimization
    1) Operational Excellence pillar focuses on running and monitoring systems to deliver business value and continually improving processes and procedures.
    3) Reliability pillar focuses on the ability to prevent and quickly recover from failures to meet business and customer demand.
    4) The performance efficiency pillar focuses on using IT and computing resources efficiently. It focuses on the ability to use computing resources efficiently to meet system requirements and to maintain that efficiency as demand changes and technologies evolve.
    5) Cost optimization pillar focuses on avoiding un-needed costs by choosing the right services for the job and by right-sizing them.
238
Q

AWS Well-Architected Framework helps just read

A

The AWS Well-Architected Framework helps you understand the pros and cons of decisions you make while building systems on AWS. By using this Framework, you will learn architectural best practices for designing and operating reliable, secure, efficient, and cost-effective systems in the cloud. It provides a way for you to consistently measure your architectures against best practices and identify areas for improvement. The process for reviewing an architecture is a constructive conversation about architectural decisions and is not an audit mechanism. Having well-architected systems greatly increases the likelihood of business success.

The operational excellence pillar focuses on running and monitoring systems to deliver business value, and continually improving processes and procedures. Key topics include managing and automating changes, responding to events, and defining standards to successfully manage daily operations.

Using tools such as AWS CodeDeploy to deploy small, incremental changes to your application ensures that you do not introduce drastic updates that may affect your application entirely. Performing monthly game days allows you to test your environment for different failure scenarios so you can quickly plan out ways to remediate them.

239
Q

Just read about system manager

A

AWS Systems Manager is incorrect because although you can remotely operate and deploy packages/scripts to your on-premises servers with this one, this service is still not suitable to be used for deploying your web application. It also doesn’t have a feature to easily rollback your deployments unlike OpsWorks. This service is primarily used to automate maintenance and deployment tasks on Amazon EC2 and on-premises instances, or automatically apply patches, updates, and configuration changes across any resource group.

240
Q

Which of the following services should you use to deploy and easily rollback a web application from your Git repository to your on-premises server?

A

AWS offers services that integrate application deployment and management across on-premises and cloud environments for a robust hybrid architecture. Below are the following services that you can use to manage or deploy applications to your servers running on-premises:

OpsWorks – AWS OpsWorks is a configuration management service that helps customers configure and operate applications, both on-premises and in the AWS Cloud, using Chef and Puppet.

CodeDeploy – AWS CodeDeploy automates code deployments to any instance, including Amazon EC2 instances and instances running on-premises. AWS CodeDeploy makes it easier to rapidly release new features, avoids downtime during application deployment, and handles the complexity of updating applications.

252
Q

Which of the following do you need to programmatically interact with your AWS environment? (Select TWO.)

A

You use can AWS SDKs to programmatically interact with your AWS resources. Using access keys, which are unique identifiers for your IAM user, you can connect to your resources in a secure manner.

The AWS Access Key ID and AWS Secret Access Key are your AWS credentials. They are associated with an AWS Identity and Access Management (IAM) user or role that determines what permissions you have.
Access keys are long-term credentials for an IAM user or the AWS account root user. You can use access keys to sign programmatic requests to the AWS CLI or AWS API (directly or using the AWS SDK). If you don’t have access keys, you can create them from the AWS Management Console. As a best practice, do not use the AWS account root user access keys for any task where it’s not required. Instead, create a new administrator IAM user with access keys for yourself.

253
Q

AWS golden AMI

A

A golden AMI is an AMI that contains the latest security patches, software, configuration, and software agents that you need to install for logging, security maintenance, and performance monitoring.

An AMI includes the following:

  • One or more EBS snapshots, or, for instance-store-backed AMIs, a template for the root volume of the instance (for example, an operating system, an application server, and applications).
  • Launch permissions that control which AWS accounts can use the AMI to launch instances.
  • A block device mapping that specifies the volumes to attach to the instance when it’s launched.

Hence, the correct answer is: Create a golden AMI of the instance and copy it to the other Region.

254
Q

AWS KMS or Key Management Service

A

AWS KMS or Key Management Service is incorrect because this is a central repository for encryption keys in your account. It is not used to protect your network from potential security threats.

Restricting access to Amazon S3 content by using an origin access identity (OAI)
PDF

Kindle

RSS

To restrict access to content that you serve from Amazon S3 buckets, follow these steps:

Create a special CloudFront user called an origin access identity (OAI) and associate it with your distribution.

Configure your S3 bucket permissions so that CloudFront can use the OAI to access the files in your bucket and serve them to your users. Make sure that users can’t use a direct URL to the S3 bucket to access a file there.

After you take these steps, users can only access your files through CloudFront, not directly from the S3 bucket.
