- Savings Plans
Explanation
Correct Answer
A:EC2 On-Demand Instances fits the need because on-Demand pricing gives flexible capacity for irregular or new workloads, generally without the discounts of eligible commitments. The relevant capability or responsibility is: Pay for eligible compute usage without a long-term purchase commitment.
Incorrect Answers
B:On-Demand Capacity Reservations is associated with a different use case: a business needs assurance that EC2 capacity will be available in a chosen Availability Zone for a planned event. An On-Demand Capacity Reservation addresses EC2 capacity availability rather than by itself providing a commitment pricing reduction. The question instead focuses on a company needs compute capacity for a short unpredictable project and does not want a long commitment; EC2 On-Demand Instances is the more direct match.
C:Spot Instances is associated with a different use case: a research team runs flexible batch processing jobs that can tolerate interruption. EC2 Spot Instances offer discounted unused capacity but can be reclaimed with interruption notices. The question instead focuses on a company needs compute capacity for a short unpredictable project and does not want a long commitment; EC2 On-Demand Instances is the more direct match.
D:Savings Plans is associated with a different use case: a business expects steady eligible compute spending and can commit to a consistent hourly amount. Savings Plans provide discounts for covered usage in exchange for a one- or three-year commitment to an hourly spend amount. The question instead focuses on a company needs compute capacity for a short unpredictable project and does not want a long commitment; EC2 On-Demand Instances is the more direct match.
Question 666
Which AWS service or cloud principle is the BEST fit for this outcome or responsibility: support a managed relational database compatible with supported engines?

Explanation
Correct Answer
B:Amazon Aurora directly addresses this outcome. Aurora is an AWS-managed relational database designed for cloud operation and compatible with selected open-source SQL engines. A common relevant example is: a growing business wants a cloud-optimized managed relational engine compatible with MySQL or PostgreSQL.
Incorrect Answers
A:Amazon DynamoDB instead focuses on a different requirement, such as a game needs low-latency access to large volumes of key-value player state without managing servers. DynamoDB supports key-value and document data models and is not a general-purpose relational SQL database. It is not the primary match for the requirement described here: support a managed relational database compatible with supported engines.
C:Amazon RDS relational database instead focuses on a different requirement, such as a web application needs a managed relational database that supports SQL queries and transactions. RDS manages selected database infrastructure work for relational workloads, while users still control database schema and access. It is not the primary match for the requirement described here: support a managed relational database compatible with supported engines.
D:Amazon ElastiCache instead focuses on a different requirement, such as a shopping service needs fast in-memory access to frequently requested session information. ElastiCache reduces repeated backend reads by keeping appropriate data in memory for fast access. It is not the primary match for the requirement described here: support a managed relational database compatible with supported engines.
Question 667

C:AWS Security Hub fits the need because security Hub centralizes security posture information and findings rather than storing application business data. The relevant capability or responsibility is: Aggregate and prioritize security findings with AWS Security Hub.
Incorrect Answers
A:Amazon GuardDuty threat detection is associated with a different use case: a security team wants managed detection of suspicious activity from AWS account and workload signals. GuardDuty analyzes signals for suspicious or malicious behavior rather than acting as a general-purpose firewall. The question instead focuses on a security operations team wants a consolidated view of findings from multiple AWS security services; AWS Security Hub is the more direct match.
B:AWS Artifact compliance reports is associated with a different use case: an auditor asks a company for AWS third-party compliance and assurance documentation. AWS Artifact gives customers on-demand access to available AWS assurance reports and selected compliance agreements. The question instead focuses on a security operations team wants a consolidated view of findings from multiple AWS security services; AWS Security Hub is the more direct match.
D:Encryption in transit is associated with a different use case: a company wants to protect data while it moves between clients and an online service. Encryption in transit protects communications over networks; it differs from encryption of data stored on disks. The question instead focuses on a security operations team wants a consolidated view of findings from multiple AWS security services; AWS Security Hub is the more direct match.
