Q1. Can resource record sets in a hosted zone have a different domain suffix (for example, www.bIog. acme.com and www.acme.ca)?

A. Yes, it can have for a maximum of three different TLDs.

B. Yes

C. Yes, it can have depending on the TLD.

D. No

Answer: D

Explanation:

The resource record sets contained in a hosted zone must share the same suffix. For example, the exampIe.com hosted zone can contain resource record sets for www.exampIe.com and wvvw.aws.exampIe.com subdomains, but it cannot contain resource record sets for a www.exampIe.ca subdomain.

Q2. You are the new IT architect in a company that operates a mobile sleep tracking application

When activated at night, the mobile app is sending collected data points of 1 kilobyte every 5 minutes to

your backend

The backend takes care of authenticating the user and writing the data points into an Amazon DynamoDB table.

Every morning, you scan the table to extract and aggregate last night's data on a per user basis, and store the results in Amazon 53.

Users are notified via Amazon 5NI5 mobile push notifications that new data is available, which is parsed and visualized by (The mobile app Currently you have around IOOk users who are mostly based out of North America.

You have been tasked to optimize the architecture of the backend system to lower cost what would you recommend? (Choose 2 answers}

A. Create a new Amazon DynamoDB (able each day and drop the one for the previous day after its data is on Amazon 53.

B. Have the mobile app access Amazon DynamoDB directly instead of J50N files stored on Amazon 53.

C. Introduce an Amazon SQS queue to buffer writes to the Amazon DynamoDB table and reduce provisioned write throughput.

D. Introduce Amazon Elasticache Io cache reads from the Amazon DynamoDB table and reduce provisioned read throughput.

E. Write data directly into an Amazon Redshift cluster replacing both Amazon DynamoDB and Amazon 53.

Answer: B, D

Q4. 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. AWS Import/Export

B. AWS CIoudFormation

C. Amazon Route 53

D. Amazon CIoudWatch

Answer: B

Explanation:

AWS CIoudFormation 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 CIoudFormation takes care of provisioning and configuring those resources for you. You don't need to indMdually create and configure AWS resources

and figure out what's dependent on what. AWS CIoudFormation handles all of that.

Q5. What happens to the 1/0 operations while you take a database snapshot?

A. 1/0 operations to the database are suspended for a few minutes while the backup is in progress.

B. 1/0 operations to the database are sent to a Replica (if available) for a few minutes while the backup is in progress.

C. 1/0 operations will be functioning normally

D. 1/0 operations to the database are suspended for an hour while the backup is in progress

Answer: A

Q6. You are using Amazon SES as an email solution but are unsure of what its limitations are. Which statement below is correct in regards to that?

A. New Amazon SES users who have received production access can send up to 1,000 emails per 24-hour period, at a maximum rate of 10 emails per second.

B. Every Amazon SES sender has a the same set of sending limits

C. Sending limits are based on messages rather than on recipients

D. Every Amazon SES sender has a unique set of sending limits

Answer: D

Explanation:

Amazon Simple Email Service (Amazon SES) is a highly scalable and cost-effective email-sending

service for businesses and developers. Amazon SES eliminates the complexity and expense of building an in-house email solution or licensing, installing, and operating a third-party email service for this type of email communication.

Every Amazon SES sender has a unique set of sending limits, which are calculated by Amazon SES on an ongoing basis:

Sending quota — the maximum number of emails you can send in a 24-hour period. Maximum send rate — the maximum number of emails you can send per second.

New Amazon SES users who have received production access can send up to 10,000 emails per 24-hour period, at a maximum rate of 5 emails per second. Amazon SES automatically adjusts these limits upward, as long as you send high-quality email. If your existing quota is not adequate for your needs and the system has not automatically increased your quota, you can submit an SES Sending Quota Increase case at any time.

Sending limits are based on recipients ratherthan on messages. You can check your sending limits at any time by using the Amazon SES console.

Note that if your email is detected to be of poor or QUESTION able quality (e.g., high complaint rates, high bounce rates, spam, or abusive content), Amazon SES might temporarily or permanently reduce your permitted send volume, or take other action as AWS deems appropriate.

Q7. An administrator is using Amazon CIoudFormation to deploy a three tier web application that consists of a web tier and application tier that will utilize Amazon DynamoDB for storage when creating the CIoudFormation template which of the following would allow the application instance access to the DynamoDB tables without exposing API credentials?

A. Create an Identity and Access Management Role that has the required permissions to read and write from the required DynamoDB table and associate the Role to the application instances by referencing an instance profile.

B. Use the Parameter section in the Cloud Formation template to nave the user input Access and Secret Keys from an already created IAM user that has me permissions required to read and write from the required DynamoDB table.

C. Create an Identity and Access Management Role that has the required permissions to read and write from the required DynamoDB table and reference the Role in the instance profile property of the application instance.

D. Create an identity and Access Management user in the CIoudFormation template that has permissions to read and write from the required DynamoDB table, use the GetAtt function to retrieve the Access and secret keys and pass them to the application instance through user-data.

Answer: C

Q8. A user has set up the CIoudWatch alarm on the CPU utilization metric at 50%, with a time interval of 5 minutes and 10 periods to monitor. What will be the state of the alarm at the end of 90 minutes, if the CPU utilization is constant at 80%?

A. ALERT

B. ALARM

C. OK

D. INSUFFICIENT_DATA

Answer: B

Explanation:

In this case the alarm watches a metric every 5 minutes for 10 intervals. Thus, it needs at least 50 minutes to come to the "OK" state.

Till then it will be in the |NSUFFUCIENT_DATA state.

Since 90 minutes have passed and CPU utilization is at 80% constant, the state of alarm will be "ALARNI". Reference: http://docs.aws.amazon.com/AmazonCIoudWatch/latest/DeveloperGuide/AlarmThatSendsEmaiI.html

Q9. You have just set up a large site for a client which involved a huge database which you set up with Amazon RDS to run as a Mu|ti-AZ deployment. You now start to worry about what will happen if the database instance fails. Which statement best describes how this database will function if there is a database failure?

A. Updates to your DB Instance are synchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.

B. Your database will not resume operation without manual administrative intervention.

C. Updates to your DB Instance are asynchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.

D. Updates to your DB Instance are synchronously replicated across S3 to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.

Answer: A

Explanation:

Amazon Relational Database Service (Amazon RDS) is a managed service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity, while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.

When you create or modify your DB Instance to run as a MuIti-AZ deployment, Amazon RDS automatically provisions and maintains a synchronous "standby" replica in a different Availability Zone. Updates to your DB Instance are synchronously replicated across Availability Zones to the standby in order to keep both in sync and protect your latest database updates against DB Instance failure.

During certain types of planned maintenance, or in the unlikely event of DB Instance failure or Availability Zone failure, Amazon RDS will automatically failover to the standby so that you can resume database writes and reads as soon as the standby is promoted. Since the name record for your DB Instance

remains the same, you application can resume database operation without the need for manual administrative intervention. With Mu|ti-AZ deployments, replication is transparent: you do not interact directly with the standby, and it cannot be used to serve read traffic. If you are using Amazon RDS for MySQL and are looking to scale read traffic beyond the capacity constraints of a single DB Instance, you can deploy one or more Read Replicas.

Q10. A gaming company comes to you and asks you to build them infrastructure for their site. They are not sure how big they will be as with all start ups they have limited money and big ideas. What they do tell you is that if the game becomes successful, like one of their previous games, it may rapidly grow to millions of users and generate tens (or even hundreds) of thousands of writes and reads per second. After

considering all of this, you decide that they need a fully managed NoSQL database service that provides fast and predictable performance with seamless scalability. Which of the following databases do you think would best fit their needs?

A. Amazon DynamoDB

B. Amazon Redshift

C. Any non-relational database.

D. Amazon SimpIeDB

Answer: A

Explanation:

Amazon DynamoDB is a fully managed NoSQL database service that provides fast and predictable

performance with seamless scalability. Amazon DynamoDB enables customers to offload the administrative burdens of operating and scaling distributed databases to AWS, so they don’t have to worry about hardware provisioning, setup and configuration, replication, software patching, or cluster scaHng.

Today’s web-based applications generate and consume massive amounts of data. For example, an

online game might start out with only a few thousand users and a light database workload consisting of 10 writes per second and 50 reads per second. However, if the game becomes successful, it may rapidly grow to millions of users and generate tens (or even hundreds) of thousands of writes and reads per second. It may also create terabytes or more of data per day. Developing your applications against Amazon DynamoDB enables you to start small and simply dial-up your request capacity for a table as your requirements scale, without incurring downtime. You pay highly cost-efficient rates for the request capacity you provision, and let Amazon DynamoDB do the work over partitioning your data and traffic over sufficient server capacity to meet your needs. Amazon DynamoDB does the database management and administration, and you simply store and request your data. Automatic replication and failover provides built-in fault tolerance, high availability, and data durability. Amazon DynamoDB gives you the peace of mind that your database is fully managed and can grow with your application requirements. Reference: http://aws.amazon.com/dynamodb/faqs/
