AWS Certified Solutions Architect – Associate Questions and Answers (Dumps and Practice Questions)
Question : You have hosted your web application named www.HadoopExam.com. You are receiving logs as a continuous stream of data. For daily data analysis
you want to store this data in Redshift as well as Elastic Search Servers. Which of the following is best suitable option
1. Use AWS SQS service
2. Use AWS SNS Service
3. Use AWS CloudFront
4. Use Amazon Kinesis Firehose
Correct Answer : Get Lastest Questions and Answer :
Explanation: Amazon Kinesis is a platform for streaming data on AWS, offering powerful services to make it easy to load and analyze streaming
data, and also providing the ability for you to build custom streaming data applications for specialized needs. Web applications, mobile devices,
wearables, industrial sensors, and many software applications and services can generate staggering amounts of streaming data - sometimes TBs per hour - that need
to be collected, stored, and processed continuously. Amazon Kinesis services enable you to do that simply and at a low cost.
Firehose loads streaming data continuously into S3, redshift and Elasticsearch domains.
Question : Which of the following can be used with the Provisioned IOPS Storage
1. Multi-AZ
2. Read Replicas
3. Snapshots
4. VPC
5. All of the above
Correct Answer : Get Lastest Questions and Answer :
Using Provisioned IOPS Storage with Multi-AZ, Read Replicas, Snapshots, VPC, and DB Instance Classes
For production OLTP use cases, we recommend that you use Multi-AZ deployments for enhanced fault tolerance and Provisioned IOPS storage for fast and
predictable performance. In addition to Multi-AZ deployments, Provisioned IOPS storage complements the following features:
Amazon VPC for network isolation and enhanced security.
Read Replicas The type of storage on a read replica is independent of that on the master DB instance. For example, if the master DB instance uses
standard storage, you can add read replicas that use Provisioned IOPS storage and vice versa. If you use standard storage based read replicas with a master DB
instance that uses Provisioned IOPS storage, the performance of your read replicas may differ considerably from that of a configuration in which both the
master DB instance and the read replicas are using Provisioned IOPS storage.
DB Snapshots If you are using a DB instance that uses Provisioned IOPS storage, you can use a DB snapshot to restore an identically configured DB
instance, regardless of whether the target DB instance uses standard storage or Provisioned IOPS storage. If your DB instance uses standard storage, you can use a
DB snapshot to restore only a DB instance that uses standard storage.
You can use Provisioned IOPS storage with any DB instance class that runs the DB engine you want; however, smaller DB instance classes will not
consistently make the best use Provisioned IOPS storage. We recommend that you use Provisioned IOPS Optimized storage.
Question : As per the Government law, you have to store years sale/purchase history on www.HadoopExam.com , which is not the best solution for this
requirement. However, please note that data volume is quite high in few Tera Bytes , recent 6 month data needs to be available to use immediately and
solution should be cost effective.
1. You will be using S3
2. You will be using Amazon Redshift
3. You will be using Glacier Vault
4. You will be using both S3 and Glacier
5. You will be using EMR and Redshift
Correct Answer : Get Lastest Questions and Answer :
Explanation: As we need storage so we can use both S3 and Glacier because both are cost effective. Any data which is older than 6 month
which is less frequently used can be deleted from S3 and moved to Glacier (You can create policy ). After 5 years data can be deleted from Glacier. Please note
that data stored in Glacier will higher retrieval time like 4-5 hours.

Question : How to use Route to direct your domain to an Elastic Load Balancer fronting your web servers.
Which of the following record set, you will create ?
1. AAAA
2. A
3. Access Mostly Uused Products by 50000+ Subscribers
4. MX
Ans : 3
Exp : The AWS::Route53::RecordSet type can be used as a standalone resource or as an embedded property in the AWS::Route53::RecordSetGroup type.
Note that some AWS::Route53::RecordSet properties are valid only when used within AWS::Route53::RecordSetGroup.
Note that before you use AWS CloudFormation to add a recordset to hosted zone, that hosted zone must already be created in Amazon Route 53.
AWS CloudFormation does not create new hosted zones.
In CloudFront, an alternate domain name, also known as a CNAME, lets you use your own domain name (for example, www.example.com)
for links to your objects instead of using the domain name that CloudFront assigns to your distribution.
Both web and RTMP distributions support alternate domain names.
When you create a distribution, CloudFront returns a domain name for the distribution, for example:
d111111abcdef8.cloudfront.net
When you use the CloudFront domain name for your objects, the URL for an object called /images/image.jpg is:
http://d111111abcdef8.cloudfront.net/images/image.jpg
If you want to use your own domain name, such as www.example.com, instead of the cloud
front.net domain name
that CloudFront assigned to your distribution, you can add an alternate domain name to your distribution for www.example.com.
You can then use the following URL for /images/image.jpg:
http://www.example.com/images/image.jpg
Question : Key Pairs consist of a public and private key where you use the private key to create a digital signature,
and then AWS uses the corresponding public key to validate the signature , select the correct statement which applies correctly ?
1. Key pairs are used for all Amazon services
2. Key pairs are used only for Amazon SDKs
3. Access Mostly Uused Products by 50000+ Subscribers
4. Key pairs are used only for Elastic Load Balancing and AWS IAM
Ans : 3
Exp :
Key pairs consist of a public and private key, where you use the private key to create a digital signature,
and then AWS uses the corresponding public key to validate the signature. Key pairs are used only for Amazon EC2 and Amazon CloudFront.
For Amazon EC2, you use key pairs to access Amazon EC2 instances, such as when you use SSH to log in to a Linux instance.
For Amazon CloudFront, you use key pairs to create signed URLs for private content,
such as when you want to distribute restricted content that someone paid for.
Question : For which of the following you can apply Multifactor Authentication ?
1. Root Users
2. IAM Users
3. Access Mostly Uused Products by 50000+ Subscribers
4. Only 1,2 are correct
5. All 1,2,3 are correct
Ans : 2
Exp :AWS Multi-Factor Authentication (AWS MFA) provides an extra level of security that you can apply to your AWS environment.
With AWS MFA enabled, when you sign in to an AWS website, you are prompted for your user name and password, as well as for an
authentication code from an MFA device. Taken together, these multiple factors provide increased security for your AWS account settings and resources.
You can enable MFA for the root account and for IAM users.
Question : You are closely working with AWS solution architect and he suggested to implement auto scaling for your, website hosted on EC. Why he suggested
to use auto scaling configured for website?
A. Using Auto scaling you can divert traffic to particular instances eg 30%, 30% and 40% on three different EC2 instances.
B. You can have dynamism in your EC2 instances need, so whenever more instances required it will be launched and whenever not then they will be not
used and not charged.
C. Using auto scaling you can monitor the entire fleet of EC2 instances e.g. CPU monitoring
D. Using auto scaling will help you to send alert on your mobile using SNS. So you will get real time picture of EC2 instances.
E. Using auto scaling you can configure your own AMI and minimum number of EC2 instances.

Question : While setting up new VPC , you find only a public VPN is in place. After you created your VPC, you created a new subnet,
a new internet gateway and attached your internet gateway with your VPC. As you created your first instance in to your VPC,
you realized that you can not connect the instance even it is configured with elastic IP. What should be done to access the instance?
1. A proper KeyPair has to be setup.
2. A proper Security Group needs to be created to allow inbound and outbound traffic.
3. Access Mostly Uused Products by 50000+ Subscribers
4. A EC2 instance should be created and all traffic should be forwarded to EC2 instance.
Ans : 3
Exp : Your VPC has an implied router ,
the VPC wizard creates a route table that routes all traffic destined for an address outside the VPC to the Internet gateway,
and associates this route table with the subnet. Otherwise, you'd need to create and associate the route table yourself.
The following table shows what the route table looks like for the example addresses used in the configuration diagram
for this scenario. The first row shows the entry for local routing in the VPC; this entry enables the instances in this VPC
to communicate with each other. The second row shows the entry for routing all other subnet traffic to the Internet gateway,
which is specified using its AWS-assigned identifier.
Destination 10.0.0.0/16 Target local
Destination 0.0.0.0/0 Target igw-xxxxxxxx
