QUESTION 1
You are implementing AWS Direct Connect. You intend to use AWS public service end points such as
Amazon S3, across the AWS Direct Connect link. You want other Internet traffic to use your existing link to an Internet
Service Provider. What is the correct way to configure AWS Direct connect for access to services such as Amazon S3?
A. Configure a public Interface on your AWS Direct Connect link. Configure a static route via your AWS Direct Connect
link that points to Amazon S3 Advertise a default route to AWS using BGP.
B. Create a private interface on your AWS Direct Connect link. Configure a static route via your AWS Direct connect link
that points to Amazon S3 Configure specific routes to your network in your VPC,
C. Create a public interface on your AWS Direct Connect link. Redistribute BGP routes into your existing routing
infrastructure advertise specific routes for your network to AWS.
D. Create a private interface on your AWS Direct connect link. Redistribute BGP routes into your existing routing
infrastructure and advertise a default route to AWS.

QUESTION 3
A company will run different data analytics jobs on large petabyte-scale datasets, using standard SQL and existing
business intelligence tools. The data is mostly structured, but part of the data is unstructured and resides in Amazon S3.
What technology should be used to support this use case?
A. An Amazon Aurora database cluster with 15 replicas distributed across Availability Zones.
B. Amazon Redshift with Amazon Redshift Spectrum.
C. Amazon DynamoDB with Amazon DynamoDB Accelerator (DAX).
D. Amazon ElastiCache for Redis with cluster mode enabled.
Correct Answer: B
For data warehousing, Amazon Redshift provides the ability to run complex, analytic queries against petabytes of
structured data, and includes Redshift Spectrum that runs SQL queries directly against Exabytes of structured or
unstructured data in S3 without the need for unnecessary data movement.

QUESTION 8
A Solutions Architect is building an application on AWS that will require 20,000 IOPS on a particular volume to support a
media event. Once the event ends, the IOPS need is no longer required. The marketing team asks the Architect to build
the platform to optimize storage without incurring downtime.
How should the Architect design the platform to meet these requirements?
A. Change the Amazon EC2 instant types.
B. Change the EBS volume type to Provisioned IOPS.
