The application needs high-performance hardware disks that provide fast I/O performance. As a Cloud Practitioner, which of the following storage options would you recommend as the MOST cost-effective solution?

Answer:

Instance Store An instance store provides temporary block-level storage for your instance. This storage is located on disks that are physically attached to the host computer. This is a good option when you need storage with very low latency, but you don't need the data to persist when the instance terminates or you can take advantage of fault-tolerant architectures. For this use-case, the computation application itself has a fault tolerant architecture, so it can automatically handle any failures of Instance Store volumes.As the Instance Store volumes are included as part of the instance's usage cost, therefore this is the correct option.

Question 2: Which of the following is a serverless AWS service?

Answer:

Lambda - AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability.

Answer:

Replacing faulty hardware of Amazon EC2 instances

• Replacing faulty hardware of Amazon EC2 instances comes under the infrastructure maintenance "of"

the cloud. This is the responsibility of AWS.Maintaining Amazon S3 data in different availability zones to keep it durable

• AWS is responsible for keeping data on AWS Cloud Secure, Durable, Available and Reliable. Keeping

data infrastructure safe from failures is the responsibility of AWS.According to the AWS Shared Responsibility Model, AWS is responsible for "Security of the Cloud".This includes protecting the infrastructure that runs all of the services offered in the AWS Cloud. This infrastructure is composed of the hardware, software, networking, and facilities that run AWS Cloud services.Question 5: Which of the following AWS services should be used to automatically distribute incoming traffic across multiple targets?

Answer:

AWS Elastic Load Balancing Elastic Load Balancing is used to automatically distribute your incoming application traffic across all the EC2 instances that you are running. You can use Elastic Load Balancing to manage incoming requests by optimally routing traffic so that no one instance is overwhelmed. Your load balancer acts as a single point of contact for all incoming web traffic to your application. When an instance is added, it needs to register with the load balancer or no traffic is routed to it. When an instance is removed, it must

deregister from the load balancer or traffic continues to be routed to it.Question 6: Which of the following are the storage services offered by the AWS Cloud? (Select two)

Answer:

S3

• Amazon Simple Storage Service (Amazon S3) is an object storage service that offers industry-leading

scalability, data availability, security, and performance.

EFS

• Amazon Elastic File System (Amazon EFS) provides a simple, scalable, fully managed elastic NFS file

system for use with AWS Cloud services and on-premises resources. It is built to scale on-demand to petabytes without disrupting applications, growing and shrinking automatically as you add and remove files, eliminating the need to provision and manage capacity to accommodate growth.Question 7: A unicorn startup is building an analytics application with support for a speech-based interface. The application will accept speech-based input from users and then convey results via speech. As a Cloud Practitioner, which solution would you recommend for the given use-case?

Answer:

Use Amazon Transcribe to convert speech to text for downstream analysis. Then use Amazon Polly to convey the text results via speech You can use Amazon Transcribe to add speech-to-text capability to your applications. Amazon Transcribe uses a deep learning process called automatic speech recognition (ASR) to convert speech to text quickly and accurately. Amazon Transcribe can be used to transcribe customer service calls, to automate closed captioning and subtitling, and to generate metadata for media assets.You can use Amazon Polly to turn text into lifelike speech thereby allowing you to create applications that talk. Polly's Text-to-Speech (TTS) service uses advanced deep learning technologies to synthesize natural sounding human speech.Amazon Translate is used for language translation. Amazon Translate uses neural machine translation via deep learning models to deliver more accurate and more natural-sounding translation than traditional statistical and rule-based translation algorithms.Question 8: An e-commerce company has deployed an RDS database in a single Availability Zone. The engineering team wants to ensure that in case of an AZ outage, the database should continue working on the same endpoint without any manual administrative intervention. Which of the following solutions can address this use-case?

Answer:

Configure the database in RDS Multi-AZ deployment with automatic failover to the standby When you provision a Multi-AZ DB Instance, Amazon RDS automatically creates a primary DB Instance and synchronously replicates the data to a standby instance in a different Availability Zone (AZ). In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby (or to a read replica in the case of Amazon Aurora), so that you can resume database operations as soon as the

failover is complete. Since the endpoint for your DB Instance remains the same after a failover, your application can resume database operation without the need for manual administrative intervention.Question 9: A multi-national corporation wants to get expert professional advice on migrating to AWS and managing their applications on AWS Cloud. Which of the following entities would you recommend for this engagement?
