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 the AWS service designed for speech-to-text conversion. It automatically converts audio from meetings, calls, or recordings into written text, making it suitable for creating meeting notes. The other options focus on text-to-speech (Polly), document text extraction (Textract), and image/video analysis (Rekognition).
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 the security *of* the cloud (physical data centers, hardware disposal, and hypervisor security), while customers are responsible for security *in* the cloud. This includes managing and patching the guest operating system running on their EC2 instances. Therefore, patching the guest OS with the latest security patches is the customer’s responsibility.
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 on‑premises infrastructure directly to AWS, bypassing the public internet. The other options do not create private physical connectivity (VPC is a virtual network within AWS, Route 53 is DNS, and AWS Config is a configuration management 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: Seasonal workload spikes require scaling resources up and down automatically and paying only for what is used. Auto Scaling policies dynamically adjust capacity to handle demand increases and decreases. Pay-as-you-go pricing ensures the company only pays for additional resources during peak seasons, making the solution cost-effective.
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, customers are responsible for security *in* the cloud. This includes protecting their data (such as encrypting data and ensuring data integrity) and managing identity and access management (IAM) controls like users, roles, and permissions. AWS is responsible for securing the underlying infrastructure, including the virtualization layer and Availability Zones, and for managed services like Amazon RDS, AWS handles OS patching.
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 is designed to collect configuration, usage, and dependency information from on-premises servers and applications to help plan a migration to AWS. The other options focus on data transfer, hybrid storage, or database migration rather than discovery and assessment.
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: The requirement is for a managed Network File System (NFS) that integrates with AWS compute resources. Amazon Elastic File System (Amazon EFS) is a fully managed file storage service that uses the NFS protocol and is designed to be mounted by Amazon EC2 and other AWS compute services. Amazon EBS is block storage, Storage Gateway Tape Gateway is for backup and archival, and S3 Glacier is archival object storage, not an NFS file system.
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 provision infrastructure for new applications in minutes. This directly aligns with the cloud computing advantage of increased speed and agility, which allows rapid provisioning and deployment of resources on demand. The other options address cost models, geographic reach, or capacity planning rather than setup speed.
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 sensitive information such as Amazon RDS database credentials and supports automatic, scheduled rotation of those credentials. It integrates directly with RDS to rotate passwords without application downtime, which the other options do not provide.
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 resources (targets) such as EC2 instances, containers, or IP addresses, typically across multiple Availability Zones. It does not automatically scale application resources itself (that is handled by Auto Scaling), does not span multiple AWS Regions, and does not balance traffic between internet gateways.
