Passing the Amazon AWS Certified Database - Specialty exam was a great achievement for me, and I couldn't have done it without the help of Pass4Success practice questions. The exam covered topics like managing the operational environment of a database solution and determining authentication mechanisms. One question that I recall was about designing database solutions for performance. It required a deep understanding of database optimization techniques, but I was able to answer it correctly and pass the exam.

Aced the AWS Database Specialty exam! One key area was Aurora serverless configuration. Expect questions on auto-scaling, capacity units, and use cases for serverless databases. Understand the benefits and limitations of this technology. Grateful to Pass4Success for providing relevant practice questions that helped me prepare efficiently.

Successfully completed the AWS Database Specialty cert! A challenging topic was DynamoDB design patterns. Be ready for scenarios on choosing partition keys, managing hot keys, and implementing secondary indexes. Study these concepts thoroughly. Pass4Success's exam prep materials were invaluable in covering these areas comprehensively.

Free Amazon DBS-C01 Exam Actual Questions

Note: Premium Questions for DBS-C01 were last updated On 30-07-2024 (see below)

Question #1

A company is deploying a solution in Amazon Aurora by migrating from an on-premises system. The IT department has established an AWS Direct Connect link from the company's data center. The company's Database Specialist has selected the option to require SSL/TLS for connectivity to prevent plaintext data from being set over the network. The migration appears to be working successfully, and the data can be queried from a desktop machine.

Two Data Analysts have been asked to query and validate the data in the new Aurora DB cluster. Both Analysts are unable to connect to Auror

a. Their user names and passwords have been verified as valid and the Database Specialist can connect to the DB cluster using their accounts. The Database Specialist also verified that the security group configuration allows network from all corporate IP addresses.

What should the Database Specialist do to correct the Data Analysts' inability to connect?

Reveal Solution Hide Solution
Correct Answer: B

* To connect using SSL:

* Provide the SSLTrust certificate (can be downloaded from AWS)

* Provide SSL options when connecting to database

* Not using SSL on a DB that enforces SSL would result in error

Question #2

A company wants to migrate its on-premises MySQL databases to Amazon RDS for MySQL. To comply with the company's security policy, all databases must be encrypted at rest. RDS DB instance snapshots must also be shared across various accounts to provision testing and staging environments.

Which solution meets these requirements?

Correct Answer: A

Question #3

A Database Specialist is designing a disaster recovery strategy for a production Amazon DynamoDB table. The table uses provisioned read/write capacity mode, global secondary indexes, and time to live (TTL). The Database Specialist has restored the latest backup to a new table.

To prepare the new table with identical settings, which steps should be performed? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: B, C

The following items need to be reconfigured after restoring the DynamoDB table.

--AutoScaling policy

--IAM policy

--CloudWatch settings

--Tags

--Stream settings

--TTL

Question #4

A company is running Amazon RDS for MySQL for its workloads. There is downtime when AWS operating system patches are applied during the Amazon RDS-specified maintenance window.

What is the MOST cost-effective action that should be taken to avoid downtime?

Reveal Solution Hide Solution
Correct Answer: D

https://aws.amazon.com/premiumsupport/knowledge-center/rds-required-maintenance/

To minimize downtime, modify the Amazon RDS DB instance to a Multi-AZ deployment. For Multi-AZ deployments, OS maintenance is applied to the secondary instance first, then the instance fails over, and then the primary instance is updated. The downtime is during failover. For more information, see Maintenance for Multi-AZ Deployments. https://aws.amazon.com/rds/faqs/ The availability benefits of Multi-AZ also extend to planned maintenance. For example, with automated backups, I/O activity is no longer suspended on your primary during your preferred backup window, since backups are taken from the standby. In the case of patching or DB instance class scaling, these operations occur first on the standby, prior to automatic fail over. As a result, your availability impact is limited to the time required for automatic failover to complete.


Question #5

A Database Specialist needs to speed up any failover that might occur on an Amazon Aurora PostgreSQL DB cluster. The Aurora DB cluster currently includes the primary instance and three Aurora Replicas.

How can the Database Specialist ensure that failovers occur with the least amount of downtime for the application?
