Under the shared responsibility model, which of the following is the customer responsible for?

1) Ensuring that firmware is updated on hardware devices.

2) Ensuring that disk drives are wiped after use.

3) Ensuring that data is encrypted at rest.

4) Ensuring that network cables are category six or higher.

Answer:

3) Ensuring that data is encrypted at rest.

Explanation:

“Data configuration (i.e. encrypting data at rest and in transit) is the responsibility of the customer”

According to the Shared Responsibility Model, AWS is responsible for the underlying integrity and security of AWS physical resources, but not the integrity of the data and configurations added by customers.

Which allows companies to track and categorize spending on a detailed level?

1) Cost allocation tags

2) Consolidated billing

3) AWS Budgets

4) AWS Marketplace

Answer:

1) Cost allocation tags

Explanation:

“After you activate cost allocation tags, AWS uses the cost allocation tags to organize your resource costs on your cost allocation report, to make it easier for you to categorize and track your AWS costs”

Reference:

Stores objects, provides real-time access to those objects, and offers versioning and lifecycle capabilities:

1) Amazon Glacier

2) AWS Storage Gateway

3) Amazon S3

4) Amazon EBS

Answer:

3) Amazon S3

Explanation:

Compared to block storage, object storage is much newer. With object storage, data is bundled with customizable metadata tags and a unique identifier to form objects. The metadata tags are a key advantage with object storage — they allow for much better identification and classification of data.

Example of object storage: Amazon S3

Versioning in Amazon S3 is a means of keeping multiple variants of an object in the same bucket. You can use the S3 Versioning feature to preserve, retrieve, and restore every version of every object stored in your buckets. With versioning, you can recover more easily from both unintended user actions and application failures. After versioning is enabled for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of those objects.

Answer is NOT EBS because that stores blocks, not objects

Block storage is the oldest and simplest form of data storage. Block storage stores data in fixed-sized chunks called — you guessed it — ‘blocks’. By itself, a block typically only houses a portion of the data.

Distributing workloads across multiple Availability Zones supports which cloud architecture design principle?

1) Implement automation.

2) Design for agility

3) Design for failure.

4) Implement elasticity.

Answer:

3) Design for failure

Explanation:

Using multiple-AZs removes single points of failure, which is part of design for failure (part of ‘Reliability Design Principles and Best Practices’)

Each Availability Zone is engineered to be independent of failures in other Availability Zones.

An example of an implementation designed for failure:

A fleet of application servers can be distributed across multiple Availability Zones and be attached to ELB.

When the EC2 instances of a particular Availability Zone fail their health checks, ELB stops sending traffic to those nodes.

In addition, AWS Auto Scaling ensures that the correct number of EC2 instances are available to run your application, launching and terminating instances based on demand and defined by your scaling policies.
