1. Which AWS service is used to provide a logically isolated section of the AWS
Cloud where you can launch AWS resources in a virtual network that you define?
A. AWS Direct Connect
B. Amazon VPC
C. AWS VPN
D. Amazon Route 53
🟢B
🔴 Explanation: Amazon Virtual Private Cloud (VPC) allows you to provision a logically
isolated section of the AWS Cloud where you can launch AWS resources in a virtual
network that you define. Direct Connect (A) is a dedicated network connection, AWS VPN
(C) connects networks securely, and Route 53 (D) is a DNS service.
2. A company is looking to store data that is infrequently accessed but must be
immediately available when requested. Which Amazon S3 storage class is the
MOST cost-effective for this use case?
A. S3 Standard
B. S3 Glacier Deep Archive
C. S3 One Zone-IA
D. S3 Standard-IA
🟢D
🔴 Explanation: S3 Standard-IA (Infrequent Access) is designed for data that is accessed
less frequently but requires rapid access when needed. S3 Standard (A) is for frequently
accessed data, S3 Glacier Deep Archive (B) is for long-term archival with retrieval hours,
and S3 One Zone-IA (C) is less resilient as it does not replicate across Availability Zones.
3. Under the AWS Shared Responsibility Model, which of the following is the
responsibility of the customer?
A. Patching the operating system of Amazon RDS instances
B. Securing the physical infrastructure of AWS data centers
C. Managing the hypervisor layer for EC2 instances
D. Configuring security groups and network access control lists
🟢D
🔴 Explanation: The customer is responsible for security in the cloud, which includes
configuring security groups and NACLs. Patching the OS of RDS instances (A) and
,managing the hypervisor (C) are AWS's responsibility. Securing physical infrastructure (B)
is also AWS's responsibility.
4. What is the primary benefit of using AWS Global Accelerator?
A. It caches content at edge locations for faster delivery.
B. It provides a static IP address that acts as a fixed entry point to an application.
C. It translates domain names to IP addresses.
D. It improves the availability and performance of applications by directing traffic over
the AWS global network.
🟢D
🔴 Explanation: AWS Global Accelerator improves application performance and availability
by directing user traffic over the AWS global network to the optimal endpoint. CloudFront
(A) caches content. Route 53 (C) translates domain names. While it does provide static IPs
(B), the primary benefit is performance and availability via the AWS network.
5. Which of the following is a characteristic of AWS Regions?
A. They are a single data center.
B. They are a collection of Availability Zones.
C. They are geographically isolated from each other by default.
D. They are interconnected with high-bandwidth, low-latency networks, but are
physically separated.
🟢B
🔴 Explanation: An AWS Region is a physical location in the world where AWS clusters
data centers, which are called Availability Zones. Regions are a collection of these zones.
While they are geographically separate and interconnected, their defining characteristic
for the exam is that they are a collection of Availability Zones.
6. A company wants to run a high-performance computing (HPC) workload that is
tightly coupled and requires very low latency between nodes. Which EC2
placement group should they use?
A. Cluster Placement Group
B. Partition Placement Group
C. Spread Placement Group
D. Auto Scaling Group
🟢A
🔴 Explanation: A Cluster Placement Group is designed for HPC applications that require
low network latency and high network throughput within a single Availability Zone.
Partition (B) distributes instances across partitions, Spread (C) distributes across distinct
hardware, and Auto Scaling (D) is for scaling capacity.
, 7. Which AWS service allows you to allocate and manage Elastic IP addresses?
A. AWS Shield
B. Amazon VPC
C. AWS WAF
D. AWS Config
🟢B
🔴 Explanation: Elastic IP addresses are allocated and managed within the context of a
Virtual Private Cloud (VPC). They are a feature of the VPC service, not Shield (A), WAF (C),
or Config (D), which are security and compliance services.
8. A developer needs a fully managed document database that supports JSON-like
data. Which AWS service should they use?
A. Amazon RDS
B. Amazon DynamoDB
C. Amazon DocumentDB
D. Amazon Aurora
🟢C
🔴 Explanation: Amazon DocumentDB is a fully managed document database service that
is compatible with MongoDB and is designed to store, query, and index JSON-like data.
RDS (A) and Aurora (D) are relational databases, while DynamoDB (B) is a key-value and
document database, but DocumentDB is explicitly designed for JSON-like workloads.
9. What is the primary purpose of AWS Organizations?
A. To provide a single, unified billing for multiple AWS accounts.
B. To provide a firewall for a single AWS account.
C. To manage virtual private networks.
D. To provide a global content delivery network.
🟢A
🔴 Explanation: The primary purpose of AWS Organizations is to centrally manage billing
and governance across multiple AWS accounts. This includes consolidated billing and
policy-based management. It is not a firewall (B), VPN manager (C), or CDN (D).
10. Which of the following is a benefit of the AWS Well-Architected Framework?
A. It guarantees a 100% uptime for all applications.
B. It provides a set of best practices to help architects build secure, high-performing,
resilient, and efficient infrastructure.
C. It automatically optimizes AWS costs.
D. It is a mandatory compliance requirement for all AWS users.
🟢B
🔴 Explanation: The AWS Well-Architected Framework provides a set of best practices and
guidelines to help architects build secure, high-performing, resilient, and efficient
