A 3-tier e-commerce web application is current deployed on-premises and will be
migrated to AWS for greater scalability and elasticity The web server currently
shares read-only data using a network distributed file system The app server tier
uses a clustering mechanism for discovery and shared session state that depends
on IP multicast The database tier uses shared-storage clustering to provide
database fall over capability, and uses several read slaves for scaling Data on all
servers and the distributed file system directory is backed up weekly to off-site tapes
Which AWS storage and database architecture meets the requirements of the
application?
A. Web servers, store read-only data in S3, and copy from S3 to root volume at boot
time App servers snare state using a combination or DynamoDB and IP unicast

B
Your website is serving on-demand training videos to your workforce. Videos are
uploaded monthly in high resolution MP4 format. Your workforce is distributed
globally often on the move and using company-provided tablets that require the
HTTP Live Streaming (HLS) protocol to watch a video. Your company has no video
transcoding expertise and it required you may need to pay for a consultant.
How do you implement the most cost-efficient architecture without compromising
high availability and quality of video delivery'?
,A. Elastic Transcoder to transcode original high-resolution MP4 videos to HLS S3 to
host videos with Utecycle Management to archive original flies to Glacier after a few
days
CloudFront to serve HLS transcoded videos from S3
B. A video transcoding pipeline running on EC2 using SQS to distribute tasks and
Auto Scaling to adjust the number or nodes depending on the length of the queue S3

You are migrating a legacy client-server application to AWS The application
responds to a specific DNS domain (e g www example com) and has a 2-tier
architecture, with multiple application servers and a database server Remote clients
use TCP to connect to the application servers. The application servers need to know
the IP address of the clients in order to function properly and are currently taking that
information from the TCP socket A Multi-AZ RDS MySQL instance will be used for
the database.
During the migration you can change the application code but you have to file a
change request.
How would you implement the architecture on AWS In order to maximize scalability
and high ability?
File a change request to implement Proxy Protocol support In the application Use an
EL8 with a TCP Listener and Proxy Protocol enabled to distribute load on two
application servers in different AZs.
File a change r - Answer-D
A web company is looking to implement an intrusion detection and prevention
system into their deployed VPC. This platform should have the ability to scale to
thousands of instances running inside of the VPC.
How should they architect their solution to achieve these goals?
A. Configure an instance with monitoring software and the elastic network interface
(ENI) set to promiscuous mode packet sniffing to see an traffic across the VPC.
B. Create a second VPC and route all traffic from the primary application VPC
through the second VPC where the scalable virtualized IDS/IPS platform resides.
C. Configure servers running in the VPC using the host-based 'route' commands to
send all traffic through the platform to a scalable virtualized IDS/IPS.
D. Configure each host with an agent that collects all network traffic and sends that
traffic to the IDS/IPS platform for inspection. - Answer-C
Your customer wishes to deploy an enterprise application to AWS which will consist
of several web servers, several application servers and a small (50GB) Oracle
database
information is stored, both in the database and the file systems of the various
servers. The backup system must support database recovery whole server and
whole disk restores, and individual file restores with a recovery time of no more than
two hours. They have chosen to use RDS Oracle as the database
Which backup architecture will meet these requirements?

dependencies without being reconfigured? (Choose 3 answers)
An AWS Direct Connect link between the VPC and the network housing the internal
services.
An Internet Gateway to allow a VPN connection.
An Elastic IP address on the VPC instance

A. Use AWS data Pipeline to schedule a DynamoDB cross region copy once a day.
create a Lastupdated' attribute in your DynamoDB table that would represent the
timestamp of the last update and use it as a filter.
B. Use EMR and write a custom script to retrieve d - Answer-C
