Select the ONE option that describes the mechanism used to extract metrics associated with deadlocks and multi threading problems SELECT ONE OPTION

• A. Scan server logs and compile metrics from them.
• B. Direct measurement from a dynamic performance test.
• C. Direct measurement through a performance monitoring tool.
• D. Analysis and elaboration of metrics from a dynamic performance test.

Which ONE of the following options represents a principle of performance testing?
SELECT ONE OPTION

• A. The tests must be aligned with the defined expectations of different stakeholder groups, users In particular, system designers and operations staff
• B. The tests can only be conducted, where resources allow, on complete systems and test environments that are representative of the production system.
• C. The tests must be reproducible. Identical results must be obtained by repeating the tests on an unchanged system.
• D. The tests must yield results that are both understandable and can be readily compared to the requirements desired by the technical team.

Identify the correspondences between architectures (from 1 to 4) and their characteristic risks (from A to D).
1. Dynamlc/cloud-based systems.
2. Client-server systems.
3. Multi-Tier systems.
4. Distributed systems.
1. Potential problems due to firewalls, packet inspection and server load balancing.
2. Critical workflows or dataflows to, from, or through unreliable or unpredictable remote servers, especially when such servers suffer periodic connection problems or intermittent periods of intense load.
3. Failures related to the correct configuration of features such as distribution, virtualization and scaling, during the Initial configuration or subsequent updates.
4. Inadequate bandwidth or capacity on any individual server.
SELECT ONE OPTION

• A. 1C-2A-3D-4B.
• B. 1C - 2B - 3D - 4A.
• C. 1A-2C-3D-4B.
• D. 1D-2A-3C-4B

Identify the correspondences between the different tools (listed from 1 to 3) and their objectives and characteristics (listed from A to F).
1. Load generator.
2. Load management console.
3. Monitoring tool.
1. It monitors, records and/or analyzes the behavior of the component or system under test.
2. It creates the load and also collects the metrics for later communication.
3. It provides the control to start and stop the creation and execution of the user simulation.
4. It aggregates metrics from the various transactions that are defined within the load instances
5. It creates and runs multiple client instances that simulate user behavior.
6. It can effectively support a root cause analysis of performance in a system under test.
