DS0-001 Exam Dumps : CompTIA DataSys+ Certification Exam

The correct answer is B. 40%. CompTIA DataSys+ explains that Resource Governor is used to manage and allocate CPU and memory resources among multiple workloads or resource pools within a database system. When configuring resource pools, administrators must ensure that the total allocation of minimum resources does not exceed 100%, as all resource pools share the same finite system resources.

In this scenario, the first resource pool has a minimum CPU and memory allocation of 25%, and the second resource pool has a minimum allocation of 35%. Together, these minimum guarantees account for 60% of total available resources. Resource Governor enforces these minimums to ensure that critical workloads always receive their reserved share of system resources, even under heavy load.

The remaining resources are calculated by subtracting the total minimum allocation from 100%.

100% − 60% = 40%

This remaining 40% represents the maximum CPU and memory that can be safely assigned to the third resource pool without violating Resource Governor rules. Assigning a higher value would exceed the total available system resources and would not be permitted under proper configuration guidelines emphasized in DataSys+.

Option A (20%) underutilizes available resources and is unnecessarily restrictive. Option C (60%) and D (100%) are invalid because they would cause the combined minimum allocations to exceed system capacity, leading to misconfiguration or enforcement failures. DataSys+ stresses careful capacity planning when using Resource Governor to balance performance, fairness, and system stability.

Resource Governor is especially useful in multi-tenant or mixed-workload environments, where critical applications must be protected from resource starvation. Proper calculation of minimums and maximums ensures predictable performance and prevents one workload from monopolizing system resources.

Therefore, the correct maximum allocation for the third resource pool is 40%, making option B the correct and fully verified answer aligned with CompTIA DataSys+ guidance.

The characteristic of all non-relational databases is unstructured data. Unstructured data is data that does not have a predefined or fixed format, schema, or structure. Unstructured data can include various types of data, such as text, images, audio, video, etc. Non-relational databases, also known as NoSQL databases, are databases that store and manage unstructured data using different models, such as key-value, document, graph, columnar, etc. Non-relational databases are suitable for handling large volumes, variety, and velocity of data that do not fit well in the relational model. The other options are either characteristics of relational databases or not related to database types at all. For example, columns with the same data type, logical record groupings, and tabular schema are characteristics of relational databases, which are databases that store and manage structured data using tables, rows, columns, and constraints. References: CompTIA DataSys+ Course Outline, Domain 1.0 Database Fundamentals, Objective 1.1 Given a scenario, identify common database types.

The two options that can be used to protect physical database appliances from damage in a server room are fire suppression systems and cooling systems. Fire suppression systems are systems that detect and extinguish fires in a server room using water, gas, foam, or other agents. Fire suppression systems help prevent damage to physical database appliances caused by fire hazards such as overheating, electrical faults, or flammable materials. Cooling systems are systems that regulate the temperature and humidity in a server room using fans, air conditioners, chillers, or other devices. Cooling systems help prevent damage to physical database appliances caused by excessive heat or moisture that may affect their performance or lifespan. The other options are either not related or not effective for this purpose. For example, biometric access systems, camera systems, and key card systems are systems that control the access to a server room using fingerprints, facial recognition, video surveillance, or magnetic cards; these systems help prevent unauthorized entry or theft of physical database appliances, but not damage caused by environmental factors; database control systems are systems that manage the functionality and security of databases using software tools or commands; these systems help protect logical database appliances from errors or attacks, but not physical damage caused by environmental factors. References: CompTIA DataSys+ Course Outline, Domain 5.0 Business Continuity, Objective 5.4 Given a scenario, implement disaster recovery methods.
