DBS-C01 Dumps Questions With Valid Answers

The Development team recently executed a database script containing several data definition language (DDL)
and data manipulation language (DML) statements on an Amazon Aurora MySQL DB cluster. The release
accidentally deleted thousands of rows from an important table and broke some application functionality. This
was discovered 4 hours after the release. Upon investigation, a Database Specialist tracked the issue to a
DELETE command in the script with an incorrect WHERE clause filtering the wrong set of rows.
The Aurora DB cluster has Backtrack enabled with an 8-hour backtrack window. The Database Administrator
also took a manual snapshot of the DB cluster before the release started. The database needs to be returned to
the correct state as quickly as possible to resume full application functionality. Data loss must be minimal.
How can the Database Specialist accomplish this?

A company has an ecommerce web application with an Amazon RDS for MySQL DB
instance. The marketing team has noticed some unexpected updates to the product and
pricing information on the website, which is impacting sales targets. The marketing team
wants a database specialist to audit future database activity to help identify how and when
the changes are being made.
What should the database specialist do to meet these requirements? (Choose two.)

A company wants to migrate its Microsoft SQL Server Enterprise Edition database instance
from on-premises to AWS. A deep review is performed and the AWS Schema Conversion
Tool (AWS SCT) provides options for running this workload on Amazon RDS for SQL
Server Enterprise Edition, Amazon RDS for SQL Server Standard Edition, Amazon Aurora
MySQL, and Amazon Aurora PostgreSQL. The company does not want to use its own SQL
server license and does not want to change from Microsoft SQL Server.
What is the MOST cost-effective and operationally efficient solution?

A Database Specialist is setting up a new Amazon Aurora DB cluster with one primary instance and three
Aurora Replicas for a highly intensive, business-critical application. The Aurora DB cluster has one
mediumsized primary instance, one large-sized replica, and two medium sized replicas. The Database
Specialist did not assign a promotion tier to the replicas.
In the event of a primary failure, what will occur?

A business need a data warehouse system that stores data consistently and in a highly
organized fashion. The organization demands rapid response times for end-user inquiries
including current-year data, and users must have access to the whole 15-year dataset
when necessary. Additionally, this solution must be able to manage a variable volume of
incoming inquiries. Costs associated with storing the 100 TB of data must be maintained to
a minimum.
Which solution satisfies these criteria?
