Your company previously configured a heavily used, dynamically routed VPN connection between your onpremises data center and AWS. You recently provisioned a DirectConnect connection and would like to start
using the new connection. After configuring DirectConnect settings in the AWS Console, which of the following
options win provide the most seamless transition for your users?

A customer has established an AWS Direct Connect connection to AWS. The link is up and routes are beingadvertised from the customer’s end, however the customer is unable to connect from EC2 instances inside its
VPC to servers residing in its datacenter.
Which of the following options provide a viable solution to remedy this situation? (Choose two.)

Your system recently experienced down time during the troubleshooting process. You found that a new
administrator mistakenly terminated several production EC2 instances.
Which of the following strategies will help prevent a similar situation in the future?
The administrator still must be able to:
– launch, start stop, and terminate development resources.
– launch and start production instances.

Your company hosts a social media site supporting users in multiple countries. You have been asked to provide
a highly available design tor the application that leverages multiple regions tor the most recently accessed
content and latency sensitive portions of the wet) site The most latency sensitive component of the application
involves reading user preferences to support web site personalization and ad selection.
In addition to running your application in multiple regions, which option will support this application’s
requirements?

You have deployed a web application targeting a global audience across multiple AWS Regions under the
domain name.example.com. You decide to use Route53 Latency-Based Routing to serve web requests to
users from the region closest to the user. To provide business continuity in the event of server downtime you
configure weighted record sets associated with two web servers in separate Availability Zones per region.
Running a DR test you notice that when you disable all web servers in one of the regions Route53 does not
automatically direct all users to the other region. What could be happening? (Choose two.)

Your startup wants to implement an order fulfillment process for selling a personalized gadget that needs an
average of 3-4 days to produce with some orders taking up to 6 months you expect 10 orders per day on your
first day. 1000 orders per day after 6 months and 10,000 orders after 12 months.
Orders coming in are checked for consistency men dispatched to your manufacturing plant for production
quality control packaging shipment and payment processing If the product does not meet the quality standards
at any stage of the process employees may force the process to repeat a step Customers are notified via email
about order status and any critical issues with their orders such as payment failure.
Your case architecture includes AWS Elastic Beanstalk for your website with an RDS MySQL instance for
customer data and orders.
How can you implement the order fulfillment process while making sure that the emails are delivered reliably?

An ERP application is deployed across multiple AZs in a single region. In the event of failure, the Recovery
Time Objective (RTO) must be less than 3 hours, and the Recovery Point Objective (RPO) must be 15 minutes
the customer realizes that data corruption occurred roughly 1.5 hours ago.
What DR strategy could be used to achieve this RTO and RPO in the event of this kind of failure?

Your company currently has a 2-tier web application running in an on-premises data center. You have
experienced several infrastructure failures in the past two months resulting in significant financial losses. Your
CIO is strongly agreeing to move the application to AWS. While working on achieving buy-in from the other
company executives, he asks you to develop a disaster recovery plan to help improve Business continuity in the
short term. He specifies a target Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective
(RPO) of 1 hour or less. He also asks you to implement the solution within 2 weeks. Your database is 200GB insize and you have a 20Mbps Internet connection. How would you do this while minimizing costs?

Refer to the architecture diagram above of a batch processing solution using Simple Queue Service (SQS) to
set up a message queue between EC2 instances which are used as batch processors Cloud Watch monitors
the number of Job requests (queued messages) and an Auto Scaling group adds or deletes batch servers
automatically based on parameters set in Cloud Watch alarms. You can use this architecture to implement
which of the following features in a cost effective and efficient manner?

An International company has deployed a multi-tier web application that relies on DynamoDB in a single region.
For regulatory reasons they need disaster recovery capability In a separate region with a Recovery Time
Objective of 2 hours and a Recovery Point Objective of 24 hours They should synchronize their data on a
regular basis and be able to provision me web application rapidly using CloudFormation.
The objective is to minimize changes to the existing web application, control the throughput of DynamoDB used
for the synchronization of data and synchronize only the modified elements.
Which design would you choose to meet these requirements?
