CLF-C02 Cloud Technology and Services Practice Test 16 — 15 Questions

Question 1

Which AWS service provides a fully managed message broker supporting ActiveMQ and RabbitMQ protocols for migrating on-premises messaging systems to the cloud?

Accepted Answer

Amazon MQ. Amazon MQ is a fully managed message broker service that supports industry-standard protocols like AMQP (ActiveMQ) and MQTT/STOMP (RabbitMQ), making it ideal for migrating on-premises messaging systems without rewriting code. Unlike Amazon SQS or SNS, which are proprietary AWS services, Amazon MQ provides compatibility with existing ActiveMQ and RabbitMQ-based applications, enabling a seamless lift-and-shift migration to the cloud.

Answer

Amazon SQS

Answer

Amazon SNS

Answer

Amazon Kinesis Data Streams

Question 2

A company needs to implement a disaster recovery strategy where data is continuously replicated to AWS but AWS compute resources are only started during a declared disaster. Which DR strategy does this describe?

Accepted Answer

Pilot Light. The Pilot Light strategy involves continuously replicating data to AWS (e.g., using AWS Database Migration Service or S3 replication) while keeping only a minimal core set of AWS resources (like a small EC2 instance or RDS database) running. Compute resources are not fully provisioned until a disaster is declared, at which point they are scaled up to handle production traffic. This matches the description of data being continuously replicated but compute only started during a declared disaster.

Answer

Backup and Restore

Answer

Warm Standby

Answer

Multi-Site Active/Active

Question 3

Which AWS service provides a managed Kubernetes service that removes the overhead of installing, operating, and maintaining a Kubernetes control plane?

Accepted Answer

Amazon EKS. Amazon EKS (Elastic Kubernetes Service) is the correct answer because it is a managed Kubernetes service that handles the provisioning, scaling, and maintenance of the Kubernetes control plane (including the API server, etcd, and controller manager). This removes the operational overhead of installing and operating the control plane yourself, allowing you to focus on deploying and managing containerized applications.

Question 9

A company wants to deploy AWS services in a specific geographic location within a metropolitan area to reduce latency for end users in that city, while still using standard AWS APIs. Which AWS infrastructure type addresses this?

Accepted Answer

AWS Local Zones. AWS Local Zones are an infrastructure type that places compute, storage, and other select AWS services closer to end users in a specific metropolitan area, enabling single-digit millisecond latency for latency-sensitive applications while using the same AWS APIs and tools as in an AWS Region. This directly meets the requirement of reducing latency within a city without requiring custom APIs or on-premises hardware.

Answer

AWS Outposts

Answer

CloudFront Edge Locations

Answer

AWS Wavelength Zones

Question 10

Which AWS storage service is designed for shared file storage accessible simultaneously by multiple EC2 instances using the NFS protocol?

Accepted Answer

Amazon EFS. Amazon EFS (Elastic File System) is a fully managed, scalable NFS file system that can be mounted concurrently on multiple EC2 instances. It uses the NFSv4.1 protocol, enabling shared access across Availability Zones and instances, which is exactly what the question describes.

Answer

Amazon EBS

Answer

Amazon S3

Question 11

A company needs to integrate their on-premises Active Directory with AWS to enable SSO for employees accessing AWS services. Which AWS service provides this federation capability?

Accepted Answer

AWS IAM Identity Center. AWS IAM Identity Center (formerly AWS SSO) is the correct service for integrating on-premises Active Directory with AWS to enable single sign-on (SSO) for employees accessing AWS services. It supports federation via SAML 2.0 or SCIM protocols, allowing you to connect your existing AD identity source and centrally manage user access to multiple AWS accounts and business applications.

Answer

Amazon Cognito

Answer

Question 12

Which AWS service provides a private connection from an on-premises network to AWS that bypasses the public internet and provides consistent network performance?

Accepted Answer

AWS Direct Connect. AWS Direct Connect is the correct answer because it provides a dedicated, private network connection from an on-premises data center to AWS, completely bypassing the public internet. This ensures consistent network performance, lower latency, and higher bandwidth, as the connection is established through a standard 1 Gbps or 10 Gbps Ethernet fiber-optic cable linked to an AWS Direct Connect location.

Question 14

Which Amazon EC2 instance family is optimized for memory-intensive workloads such as in-memory databases, real-time big data analytics, and high-performance computing?

Accepted Answer

Memory-optimized instances (R and X family). Memory-optimized instances (R and X families) are designed for workloads that require large amounts of RAM and high memory bandwidth, such as in-memory databases (e.g., Redis, Memcached), real-time big data analytics (e.g., Apache Spark), and high-performance computing (HPC) tasks. These instances offer a high memory-to-vCPU ratio and support for large instance sizes, enabling efficient processing of data sets that reside primarily in memory.

Answer

Compute-optimized instances (C family)

Answer

Storage-optimized instances (I and D family)

Answer

Accelerated computing instances (P and G family)

Question 15

A company is running their application on EC2 instances behind an Application Load Balancer. They want to ensure the application remains available during an AZ outage. What is the minimum architecture configuration required?

Accepted Answer

EC2 instances distributed across at least two Availability Zones behind an ALB. To remain available during an Availability Zone outage, the application must be resilient to the failure of an entire AZ. An Application Load Balancer distributes traffic across healthy targets, but it cannot route to instances in a failed AZ. Therefore, EC2 instances must be deployed in at least two separate Availability Zones, and the ALB must be configured with subnets in those same AZs to route traffic and perform health checks, ensuring continuous availability if one AZ goes down.

Answer

Multiple EC2 instances in a single Availability Zone

Answer

A single large EC2 instance with enhanced networking

Answer

EC2 instances in a single Region across multiple subnets in the same AZ
