Snowflake SnowPro Advanced: Data Engineer Certification Exam Sample Questions (Q185-Q190):

NEW QUESTION # 185
A company analyzes data in a data lake every quarter to perform inventory assessments. A data engineer uses AWS Glue DataBrew to detect any personally identifiable formation (PII) about customers within the data. The company's privacy policy considers some custom categories of information to be PII. However, the categories are not included in standard DataBrew data quality rules.
The data engineer needs to modify the current process to scan for the custom PII categories across multiple datasets within the data lake.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: D


NEW QUESTION # 186
You are managing an Amazon S3 bucket used by your organization to store critical data files.
Recently, you've noticed that there have been accidental deletions and unintended modifications to important files. To address these issues, you need a strategy to ensure that you can recover previous versions of files and prevent data loss in the future.
Which S3 configuration is most suitable for protecting your data from accidental deletions and modifications while allowing you to recover previous versions of files?

Answer: A

Explanation:
Enabling S3 versioning allows you to preserve, retrieve, and restore every version of every object stored in your S3 bucket. This is the most effective method for protecting against accidental deletions and modifications because it maintains a history of changes, allowing you to recover previous versions of files.

NEW QUESTION # 187
Which Role that is dedicated to user and role management only?

Answer: D


NEW QUESTION # 188
A company hosts its applications on Amazon EC2 instances. The company must use SSL/TLS connections that encrypt data in transit to communicate securely with AWS infrastructure that is managed by a customer.
A data engineer needs to implement a solution to simplify the generation, distribution, and rotation of digital certificates. The solution must automatically renew and deploy SSL/TLS certificates.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: B

Explanation:
AWS Certificate Manager (ACM) simplifies the process of generating, distributing, and managing SSL/TLS certificates. ACM allows you to automatically renew and deploy certificates with minimal operational overhead. Once integrated with services like EC2, ACM can handle the entire lifecycle of the certificates, from creation to renewal and deployment, without manual intervention.
Managing certificates manually introduces significant operational overhead. You would need to handle generation, deployment, renewal, and rotation manually, which is error-prone and time- consuming.
While you could store certificates in AWS Secrets Manager, you would still need to implement custom scripts for certificate generation, rotation, and deployment, increasing operational complexity compared to ACM.
Amazon ECS Service Connect is used for simplifying service discovery and communication within ECS. While it can secure traffic between ECS services, it is not designed for managing SSL/TLS certificates on EC2 instances.


NEW QUESTION # 189
A company uses an Amazon QuickSight dashboard to monitor usage of one of the company's applications. The company uses AWS Glue jobs to process data for the dashboard. The company stores the data in a single Amazon S3 bucket. The company adds new data every day.
A data engineer discovers that dashboard queries are becoming slower over time. The data engineer determines that the root cause of the slowing queries is long-running AWS Glue jobs.
Which actions should the data engineer take to improve the performance of the AWS Glue jobs?
(Choose two.)

Answer: A,E
