AWS-SysOps Practice Test

An organization's security policy requires multiple copies of all critical data to be replicated
across at least a primary and backup data center. The organization has decided to store
some critical data on Amazon S3.
Which option should you implement to ensure this requirement is met?

A.

Use the S3 copy API to replicate data between two S3 buckets in different regions

B.

You do not need to implement anything since S3 data is automatically replicated
between regions

C.

Use the S3 copy API to replicate data between two S3 buckets in different facilities
within an AWS Region

D.

You do not need to implement anything since S3 data is automatically replicated
between multiple facilities within an AWS Region

Your application currently leverages AWS Auto Scaling to grow and shrink as load
Increases/ decreases and has been performing well Your marketing team expects a steady
ramp up in traffic to follow an upcoming campaign that will result in a 20x growth in traffic
over 4 weeks Your forecast for the approximate number of Amazon EC2 instances
necessary to meet the peak demand is 175.
What should you do to avoid potential service disruptions during the ramp up in traffic?

A.

Ensure that you have pre-allocated 175 Elastic IP addresses so that each server will be
able to obtain one as it launches

B.

Check the service limits in Trusted Advisor and adjust as necessary so the forecasted
count remains within limits.

C.

Change your Auto Scaling configuration to set a desired capacity of 175 prior to the
launch of the marketing campaign

D.

Pre-warm your Elastic Load Balancer to match the requests per second anticipated
during peak demand prior to the marketing campaign

You are attempting to connect to an instance in Amazon VPC without success You have
already verified that the VPC has an Internet Gateway (IGW) the instance has an
associated Elastic IP (EIP) and correct security group rules are in place.
Which VPC component should you evaluate next?

A.

The configuration of a NAT instance

B.

The configuration of the Routing Table

C.

The configuration of the internet Gateway (IGW)

D.

The configuration of SRC/DST checking

The majority of your Infrastructure is on premises and you have a small footprint on AWS
Your company has decided to roll out a new application that is heavily dependent on low
latency connectivity to LOAP for authentication Your security policy requires minimal
changes to the company's existing application user management processes.
What option would you implement to successfully launch this application1?

A.

Create a second, independent LOAP server in AWS for your application to use for
authentication

B.

Establish a VPN connection so your applications can authenticate against your existing
on-premises LDAP servers

C.

Establish a VPN connection between your data center and AWS create a LDAP replica
on AWS and configure your application to use the LDAP replica for authentication

D.

Create a second LDAP domain on AWS establish a VPN connection to establish a trust
relationship between your new and existing domains and use the new domain for
authentication

A media company produces new video files on-premises every day with a total size of
around 100GBS after compression All files have a size of 1 -2 GB and need to be uploaded
to Amazon S3 every night in a fixed time window between 3am and 5am Current upload
takes almost 3 hours, although less than half of the available bandwidth is used.
What step(s) would ensure that the file uploads are able to complete in the allotted time
window?

A.

Increase your network bandwidth to provide faster throughput to S3

B.

Upload the files in parallel to S3

C.

Pack all files into a single archive, upload it to S3, then extract the files in AWS

D.

Use AWS Import/Export to transfer the video files
