Which type of AWS storage is ephemeral and is deleted when an Amazon EC2 instance is
stopped or terminated?
A. Amazon Elastic Block Store (Amazon EBS) B. Amazon EC2 instance store C. Amazon Elastic File System (Amazon EFS) D. Amazon S3
Answer: B Explanation: Amazon EC2 instance store provides temporary block-level storage for your EC2 instance. This storage is located on disks that are physically attached to the host computer. Instance store is ideal for temporary storage of information that changes frequently, such as buffers, caches, scratch data,and other temporary content. It can also be used to store temporary data that you replicate across a fleet of instances, such as a load-balanced pool of web servers. An instance store consists of one or more instance store volumes exposed as block devices. The size of an instance store as well as the number of devices available varies by instance type and instance size. The virtual devices for instance store volumes are ephemeral[0-23]. Instance types that support one instance store volume have ephemeral0. Instance types that support two or more instance store volumes have ephemeral0, ephemeral1, and so on. Instance store pricing Instance store volumes are included as part of the instance’s usage cost. The data on an instance store volume persists even if the instance is rebooted. However, the data does not persist if the instance

Which AWS Cloud benefit is shown by an architecture’s ability to withstand failures with
minimal downtime?
A. Agility B. Elasticity C. Scalability D. High availability
Answer: D Explanation: Understanding High Availability: High availability (HA) refers to systems that are durable and likely to operate continuously without failure for a long time. HA ensures that an architecture can withstand failures with minimal downtime. Importance of High Availability: Redundancy: Systems are designed with redundancy to prevent single points of failure. Fault Tolerance: Ensures that failures do not result in significant downtime, maintaining service continuity.
Automated Recovery: Utilizes automated recovery mechanisms to quickly restore services
in the event of a failure.
AWS Services for High Availability:
Multi-AZ Deployments: Services like RDS, DynamoDB, and others support Multi-AZ
deployments for fault tolerance.
Elastic Load Balancing: Distributes traffic across multiple instances or availability zones to
ensure no single point of failure.
Auto Scaling: Automatically adjusts the number of instances based on demand, ensuring
availability even during traffic spikes.

Question # 270
Which task is the responsibility of the customer, according to the AWS shared responsibility
model?
A. Patch the Amazon DynamoDB operating system. B. Secure Amazon CloudFront edge locations by allowing physical access according to the principle of least privilege. C. Protect the hardware that runs AWS services. D. Use AWS Identity and Access Management (1AM) according to the principle of least privilege.
Answer: D Explanation: According to theAWS Shared Responsibility Model, AWS is responsible for the security "of" the cloud (such as protecting the infrastructure, including hardware, software, networking,
and facilities that run AWS Cloud services). In contrast, customers are responsible for
security "in" the cloud. This includes configuring and using AWS services securely.
D. Use AWS Identity and Access Management (IAM) according to the principle of least
privilegeis a customer's responsibility. Customers must manage their credentials, control
access to resources, and ensure that IAM policies follow the principle of least privilege,
which means granting only the permissions necessary to perform a task.
Why other options are not suitable:
A. Patch the Amazon DynamoDB operating system: AWS is responsible for managing and
patching the infrastructure for managed services like DynamoDB.
B. Secure Amazon CloudFront edge locations by allowing physical access according to the
principle of least privilege: AWS handles physical security of its edge locations.
C. Protect the hardware that runs AWS services: AWS is responsible for protecting the
physical hardware that runs AWS services.
