A video analytics organization has been acquired by a leading media company. The
analytics organization has 10 independent applications with an on-premises data
footprint of about 70TB for each application. The CTO of the media company has set a
timeline of two weeks to carry out the data migration from on-premises data center to
AWS Cloud and establish connectivity.
Which of the following are the MOST cost-effective options for completing the data
transfer and establishing connectivity? (Select two)
,Order 1 Snowmobile to complete the one-time data transfer
Setup Site-to-Site VPN to establish connectivity between the on-premises data center
and AWS Cloud
Order 70 Snowball Edge Storage Optimized devices to complete the one-time data
transfer
Setup AWS direct connect to establish connectivity between the on-premises data
center and AWS Cloud
Order 10 Snowball Edge Storage Optimized devices to complete the one-time - Correct
Answers -Setup Site-to-Site VPN to establish connectivity between the on-premises
data center and AWS Cloud
Order 10 Snowball Edge Storage Optimized devices to complete the one-time data
transfer
____
Explanation
Correct options:
Order 10 Snowball Edge Storage Optimized devices to complete the one-time data
transfer
Snowball Edge Storage Optimized is the optimal choice if you need to securely and
quickly transfer dozens of terabytes to petabytes of data to AWS. It provides up to 80
TB of usable HDD storage, 40 vCPUs, 1 TB of SATA SSD storage, and up to 40 Gb
network connectivity to address large scale data transfer and pre-processing use cases.
As each Snowball Edge Storage Optimized device can handle 80TB of data, you can
order 10 such devices to take care of the data transfer for all applications.
Exam Alert:
The original Snowball devices were transitioned out of service and Snowball Edge
Storage Optimized are now the primary devices used for data transfer. You may see the
Snowball device on the exam, just remember that the original Snowball device had
80TB of storage space.
Setup Site-to-Site VPN to establish connectivity between the on-premises data center
and AWS Cloud
AWS Site-to-Site VPN enables you to securely connect your on-premises network or
branch office site to your Amazon Virtual Private Cloud (Amazon VPC). You can
securely extend your data center or branch office network to the cloud with an AWS
Site-to-Site VPN connection. A VPC VPN Connection utilizes IPSec to establish
encrypted network connectivity between your intranet and Amazon VPC over the
Internet. VPN Connections can be configured in minutes and are a good solution if you
have an immediate need, have low to modest bandwidth requirements, and can tolerate
the inherent variability in Internet-based connectivity.
Therefore this option is the right fit for
A company manages a multi-tier social media application that runs on EC2 instances
behind an Application Load Balancer. The instances run in an EC2 Auto Scaling group
,across multiple Availability Zones and use an Amazon Aurora database. As a solutions
architect, you have been tasked to make the application more resilient to periodic spikes
in request rates.
Which of the following solutions would you recommend for the given use-case? (Select
two)
Use AWS Direct Connect
Use AWS Global Accelerator
Use AWS Shield
Use Aurora Replica
Use CloudFront distribution in front of the Application Load Balancer - Correct Answers
-Use Aurora Replica
(Correct)
Use CloudFront distribution in front of the Application Load Balancer
(Correct)
_____
Explanation
Correct options:
You can use Aurora replicas and CloudFront distribution to make the application more
resilient to spikes in request rates.
Use Aurora Replica
Aurora Replicas have two main purposes. You can issue queries to them to scale the
read operations for your application. You typically do so by connecting to the reader
endpoint of the cluster. That way, Aurora can spread the load for read-only connections
across as many Aurora Replicas as you have in the cluster. Aurora Replicas also help
to increase availability. If the writer instance in a cluster becomes unavailable, Aurora
automatically promotes one of the reader instances to take its place as the new writer.
Up to 15 Aurora Replicas can be distributed across the Availability Zones that a DB
cluster spans within an AWS Region.
Use CloudFront distribution in front of the Application Load Balancer
Amazon CloudFront is a fast content delivery network (CDN) service that securely
delivers data, videos, applications, and APIs to customers globally with low latency, high
transfer speeds, all within a developer-friendly environment. CloudFront points of
presence (POPs) (edge locations) make sure that popular content can be served
quickly to your viewers. CloudFront also has regional edge caches that bring more of
your content closer to your viewers, even when the content is not popular enough to
stay at a POP, to help improve performance for that content.
CloudFront offers an origin failover feature to help support your data resiliency needs.
CloudFront is a global service that delivers your content through a worldwide network of
, data centers called edge locations or points of presence (POPs). If your content is not
already cached in an ed
A major bank is using SQS to migrate several core banking applications to the cloud to
ensure high availability and cost efficiency while simplifying administrative complexity
and overhead. The development team at the bank expects a peak rate of about 1000
messages per second to be processed via SQS. It is important that the messages are
processed in order.
Which of the following options can be used to implement this system?
Use Amazon SQS FIFO queue in batch mode of 4 messages per operation to process
the messages at the peak rate
Use Amazon SQS standard queue to process the messages
Use Amazon SQS FIFO queue in batch mode of 2 messages per operation to process
the messages at the peak rate
Use Amazon SQS FIFO queue to process the messages - Correct Answers -Use
Amazon SQS FIFO queue in batch mode of 4 messages per operation to process the
messages at the peak rate
(Correct)
_____
Correct option:
Use Amazon SQS FIFO queue in batch mode of 4 messages per operation to process
the messages at the peak rate
Amazon Simple Queue Service (SQS) is a fully managed message queuing service that
enables you to decouple and scale microservices, distributed systems, and serverless
applications. SQS offers two types of message queues - Standard queues vs FIFO
queues.
For FIFO queues, the order in which messages are sent and received is strictly
preserved (i.e. First-In-First-Out). On the other hand, the standard SQS queues offer
best-effort ordering. This means that occasionally, messages might be delivered in an
order different from which they were sent.
By default, FIFO queues support up to 300 messages per second (300 send, receive, or
delete operations per second). When you batch 10 messages per operation (maximum),
FIFO queues can support up to 3,000 messages per second. Therefore you need to
process 4 messages per operation so that the FIFO queue can support up to 1200
messages per second, which is well within the peak rate.
The development team at an e-commerce startup has set up multiple microservices
running on EC2 instances under an Application Load Balancer. The team wants to route
traffic to multiple back-end services based on the URL path of the HTTP header. So it
