Question # 1



Recently, a gaming firm purchased a popular iOS game that is especially popular during
the Christmas season. The business has opted to include a leaderboard into the game,
which will be powered by Amazon DynamoDB. The application's load is likely to increase
significantly throughout the Christmas season.
Which solution satisfies these criteria at the lowest possible cost?

A.

DynamoDB Streams

B.

DynamoDB with DynamoDB Accelerator

C.

DynamoDB with on-demand capacity mode

D.

D.   

DynamoDB with provisioned capacity mode with Auto Scaling



Explanation: "On-demand is ideal for bursty, new, or unpredictable workloads whose
traffic can spike in seconds or minutes"
vs.
'DynamoDB released auto scaling to make it easier for you to manage capacity efficiently,
and auto scaling continues to help DynamoDB users lower the cost of workloads that have
a predictable traffic pattern."

Question # 6



A company is migrating a mission-critical 2-TB Oracle database from on premises to
Amazon Aurora. The cost for the database migration must be kept to a minimum, and both
the on-premises Oracle database and the Aurora DB cluster must remain open for write
traffic until the company is ready to completely cut over to Aurora.
Which combination of actions should a database specialist take to accomplish this
migration as quickly as possible? (Choose two.)

A.

Use the AWS Schema Conversion Tool (AWS SCT) to convert the source database
schema. Then restore the converted schema to the target Aurora DB cluster.

Explanation: https://docs.aws.amazon.com/redshift/latest/dg/concurrency-scaling.html
"With the Concurrency Scaling feature, you can support virtually unlimited concurrent users
and concurrent queries, with consistently fast query performance. When concurrency
scaling is enabled, Amazon Redshift automatically adds additional cluster capacity when
you need it to process an increase in concurrent read queries. Write operations continue as
normal on your main cluster. Users always see the most current data, whether the queries
run on the main cluster or on a concurrency scaling cluster. You're charged for concurrency
scaling clusters only for the time they're in use. For more information about pricing, see
Amazon Redshift pricing. You manage which queries are sent to the concurrency scaling
cluster by configuring WLM queues. When you enable concurrency scaling for a queue,
eligible queries are sent to the concurrency scaling cluster instead of waiting in line."
