Question 1
You need to deploy an AWS stack in a repeatable manner across multiple environments. You have selected CIoudFormation as the right tool to accomplish this, but have found that there is a resource type you need to create and model, but is unsupported by CIoudFormation. How should you overcome this chaHenge?
My answer: -
Reference answer: D
Reference analysis:

Custom resources provide a way for you to write custom provisioning logic in AWS CIoudFormation template and have AWS CIoudFormation run it during a stack operation, such as when you create, update or delete a stack. For more information, see Custom Resources.

Question 3
Which EBS volume type is best for high performance NoSQL cluster deployments?
My answer: -
Reference answer: A
Reference analysis:

io1 volumes, or Provisioned IOPS (PIOPS) SSDs, are best for: Critical business applications that require sustained IOPS performance, or more than 10,000 IOPS or 160 MiB/s of throughput per volume, like large database workloads, such as MongoDB.
Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVo|umeTypes.htm|

Question 4
What is the scope of an EBS volume?
My answer: -
Reference answer: D
Reference analysis:

An Amazon EBS volume is tied to its Availability Zone and can be attached only to instances in the same Availability Zone.
Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/resources.htmI

Question 5
Which major database needs a BYO license?
My answer: -
Reference answer: D
Reference analysis:

Oracle is not open source, and requires a bring your own license model.
Reference: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_OracIe.htm|

Question 6
There is a very serious outage at AWS. EC2 is not affected, but your EC2 instance deployment scripts stopped working in the region with the outage. What might be the issue?
My answer: -
Reference answer: B
Reference analysis:

S3 stores all snapshots. If S3 is unavailable, snapshots are unavailable.
Amazon EC2 also uses Amazon S3 to store snapshots (backup copies) of the data volumes. You can use snapshots for recovering data quickly and reliably in case of application or system failures. You can also use snapshots as a baseline to create multiple new data volumes, expand the size of an existing data volume, or move data volumes across multiple Availability Zones, thereby making your data usage highly scalable. For more information about using data volumes and snapshots, see Amazon Elastic Block Store.
Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/AmazonS3.htmI

Question 7

Question 8
You have a high security requirement for your AWS accounts. What is the most rapid and sophisticated setup you can use to react to AWS API calls to your account?
My answer: -
Reference answer: D
Reference analysis:

CloudWatch Events allow subscription to AWS API calls, and direction of these events into Kinesis Streams. This allows a unified, near real-time stream for all API calls, which can be analyzed with any tooI(s) of your choosing downstream.

Question 9
You are experiencing performance issues writing to a DynamoDB table. Your system tracks high scores for video games on a marketplace. Your most popular game experiences all of the performance issues. What is the most likely problem?
My answer: -
Reference answer: B
Reference analysis:

The primary key selection dramatically affects performance consistency when reading or writing to DynamoDB. By selecting a key that is tied to the identity of the game, you forced DynamoDB to create a hotspot in the table partitions, and over-request against the primary key partition for the popular game. When it stores data, DynamoDB dMdes a tabIe's items into multiple partitions, and distributes the data primarily based upon the partition key value. The provisioned throughput associated with a table is also dMded evenly among the partitions, with no sharing of provisioned throughput across partitions.

Question 11
You need to create a Route53 record automatically in CIoudFormation when not running in production during all launches of a Template. How should you implement this?
My answer: -
Reference answer: A
Reference analysis:

The best way to do this is with one template, and a Condition on the resource. Route53 does not allow null strings for records.
Reference:
http://docs.aws.amazon.com/AWSCIoudFormation/latest/UserGuide/conditions-section-structure.html

Question 12
When thinking of AWS OpsWorks, which of the following is not an instance type you can allocate in a stack layer?
My answer: -
Reference answer: B
Reference analysis:

AWS OpsWorks supports the following instance types, which are characterized by how they are started and stopped. 24/7 instances are started manually and run until you stop them.Time-based instances are run by AWS OpsWorks on a specified daily and weekly schedule. They allow your stack to automatically adjust the number of instances to accommodate predictable usage patterns. Load-based instances are automatically started and stopped by AWS OpsWorks, based on specified load metrics, such as CPU utilization. They allow your stack to automatically adjust the number of instances to accommodate variations in incoming traffic. Load-based instances are available only for Linux-based stacks. Reference: http://docs.aws.amazon.com/opsworks/latest/userguide/weIcome.htmI

Question 13
You need to scale an RDS deployment. You are operating at 10% writes and 90% reads, based on your logging. How best can you scale this in a simple way?
My answer: -
Reference answer: C
Reference analysis:

The high-availability feature is not a scaling solution for read-only scenarios; you cannot use a standby replica to serve read traffic. To service read-only traffic, you should use a Read Replica. For more information, see Working with PostgreSQL, MySQL, and NIariaDB Read Replicas.

Question 15
When thinking of AWS Elastic BeanstaIk's model, which is true?
My answer: -
Reference answer: C
Reference analysis:

Applications group logical services. Environments belong to Applications, and typically represent different deployment levels (dev, stage, prod, fo forth). Deployments belong to environments, and are pushes of bundles of code for the environments to run.
Reference: http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/\NeIcome.html

Question 16
Your API requires the ability to stay online during AWS regional failures. Your API does not store any state, it only aggregates data from other sources - you do not have a database. What is a simple but effective way to achieve this uptime goal?
My answer: -
Reference answer: D
Reference analysis:

standard volumes, or Magnetic volumes, are best for: Cold workloads where data is infrequently accessed, or scenarios where the lowest storage cost is important.
Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/EBSVoIumeTypes.htmI

Question 17
For AWS Auto Scaling, what is the first transition state an instance enters after leaving steady state when scaling in due to health check failure or decreased load?
My answer: -
Reference answer: A
Reference analysis:

When Auto Scaling responds to a scale in event, it terminates one or more instances. These instances are detached from the Auto Scaling group and enter the Terminating state.
Reference: http://docs.aws.amazon.com/AutoScaling/latest/DeveIoperGuide/AutoScaIingGroupLifecycIe.html

Question 18
What is the scope of an EC2 EIP?
My answer: -
Reference answer: C
Reference analysis:

An Elastic IP address is tied to a region and can be associated only with an instance in the same region. Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/resources.htmI

Question 19
You need to grant a vendor access to your AWS account. They need to be able to read protected messages in a private S3 bucket at their leisure. They also use AWS. What is the best way to accomplish this?
My answer: -
Reference answer: C
Reference analysis:

When third parties require access to your organization's AWS resources, you can use roles to delegate access to them. For example, a third party might provide a service for managing your AWS resources. With IAM roles, you can grant these third parties access to your AWS resources without sharing your AWS security credentials. Instead, the third party can access your AWS resources by assuming a role that you create in your AWS account.
