Which AWS service uses speech-to-text conversion to help users create meeting notes?
A. Amazon Polly
B. Amazon Textract
C. Amazon Rekognition
D. Amazon Transcribe
Show Answer
Correct Answer: D
Explanation: Amazon Transcribe is AWS's automatic speech recognition (ASR) service that converts spoken audio into text, making it suitable for generating meeting notes. Amazon Polly performs text-to-speech, Textract extracts text from documents, and Rekognition analyzes images and video.
Question 153
Under the AWS shared responsibility model, which of the following is a responsibility of the customer?
A. Shred disk drives before they leave a data center.
B. Prevent customers from gathering packets or collecting traffic at the hypervisor level.
C. Patch the guest operating system with the latest security patches.
D. Maintain security systems that provide physical monitoring of data centers.
Show Answer
Correct Answer: C
Explanation: Under the AWS Shared Responsibility Model, AWS is responsible for security of the cloud (physical infrastructure, data centers, hardware disposal, and hypervisor security), while customers are responsible for security in the cloud, including patching and securing the guest operating system on their EC2 instances.
Question 154
Which AWS service can create a private network connection from on premises to the AWS Cloud?
A. AWS Config
B. Virtual Private Cloud (Amazon VPC)
C. AWS Direct Connect
D. Amazon Route 53
Show Answer
Correct Answer: C
Explanation: AWS Direct Connect provides a dedicated private network connection from an on-premises environment to AWS, bypassing the public internet. Amazon VPC provides an isolated virtual network within AWS but does not itself create the private on-premises connection. AWS Config is a configuration auditing service, and Amazon Route 53 is a DNS service.
Question 155
An online retail company wants to migrate its on-premises workload to AWS. The company needs to automatically handle a seasonal workload increase in a cost-effective manner.
Which AWS Cloud features will help the company meet this requirement? (Choose two.)
A. Cross-Region workload deployment
B. Pay-as-you-go pricing
C. Built-in AWS CloudTrail audit capabilities
D. Auto Scaling policies
E. Centralized logging
Show Answer
Correct Answer: B, D
Explanation: Pay-as-you-go pricing helps control costs by charging only for the resources consumed, making it cost-effective for seasonal demand. Auto Scaling automatically adjusts compute capacity up or down based on workload, allowing the application to handle seasonal traffic increases without overprovisioning. Cross-Region deployment, CloudTrail auditing, and centralized logging do not directly address automatic scaling and cost optimization for seasonal workloads.
Question 156
Which tasks are responsibilities of the customer, according to the AWS shared responsibility model? (Choose two.)
A. Secure the virtualization layer.
B. Encrypt data and maintain data integrity.
C. Patch the Amazon RDS operating system.
D. Maintain identity and access management controls.
E. Secure Availability Zones.
Show Answer
Correct Answer: B, D
Explanation: Under the AWS shared responsibility model, AWS is responsible for security of the cloud, including the physical infrastructure, Availability Zones, and the virtualization layer, as well as patching the operating system for managed services such as Amazon RDS. Customers are responsible for security in the cloud, including encrypting and protecting their data and configuring and maintaining identity and access management (IAM) controls.
Question 157
A company plans to migrate to the AWS Cloud. The company wants to gather information about its on-premises data center.
Which AWS service should the company use to meet these requirements?
A. AWS Application Discovery Service
B. AWS DataSync
C. AWS Storage Gateway
D. AWS Database Migration Service (AWS DMS)
Show Answer
Correct Answer: A
Explanation: AWS Application Discovery Service collects configuration, usage, and dependency information from on-premises servers to help assess and plan migrations to AWS. The other services are used for data transfer (AWS DataSync), hybrid storage integration (AWS Storage Gateway), and database migration (AWS DMS), not for discovering and inventorying an on-premises environment.
Question 158
A company needs a managed NFS file system that the company can use with its AWS compute resources.
Which AWS service or feature will meet these requirements?
A. Amazon Elastic Block Store (Amazon EBS)
B. AWS Storage Gateway Tape Gateway
C. Amazon S3 Glacier Flexible Retrieval
D. Amazon Elastic File System (Amazon EFS)
Show Answer
Correct Answer: D
Explanation: Amazon Elastic File System (Amazon EFS) is a fully managed, elastic NFS file system for use with AWS compute resources such as Amazon EC2. It supports the NFS protocol and can be mounted concurrently by multiple instances. Amazon EBS provides block storage, Storage Gateway Tape Gateway is for tape backup workflows, and S3 Glacier Flexible Retrieval is archival object storage.
Question 159
A company needs to have the ability to set up infrastructure for new applications in minutes.
Which advantage of cloud computing will help the company meet this requirement?
A. Trade fixed expense for variable expense
B. Go global in minutes
C. Increase speed and agility
D. Stop guessing capacity
Show Answer
Correct Answer: C
Explanation: The requirement is to set up infrastructure for new applications in minutes. This aligns with the cloud computing advantage of increased speed and agility, which enables rapid provisioning of infrastructure and faster deployment compared to traditional environments.

Question 160
A company wants to securely store Amazon RDS database credentials and automatically rotate user passwords periodically.
Which AWS service or capability will meet these requirements?
A. Amazon S3
B. AWS Systems Manager Parameter Store
C. AWS Secrets Manager
D. AWS CloudTrail
Show Answer
Correct Answer: C
Explanation: AWS Secrets Manager is purpose-built to securely store, manage, and automatically rotate secrets such as Amazon RDS database credentials. Parameter Store can store secure parameters but automatic secret rotation for RDS is a core capability of Secrets Manager. Amazon S3 and AWS CloudTrail do not provide secure secret management with automatic credential rotation.
Question 161
What is a benefit of using an Elastic Load Balancing (ELB) load balancer with applications running in the AWS Cloud?
A. An ELB will automatically scale resources to meet capacity needs.
B. An ELB can balance traffic across multiple compute resources.
C. An ELB can span multiple AWS Regions.
D. An ELB can balance traffic between multiple internet gateways.
Show Answer
Correct Answer: B
Explanation: Elastic Load Balancing distributes incoming application traffic across multiple compute targets (such as EC2 instances, containers, and IP addresses) in one or more Availability Zones, improving availability and fault tolerance. ELB does not automatically scale application resources (Auto Scaling does), does not span multiple Regions as a single load balancer, and does not balance traffic between internet gateways.
