To determine the number of partitions using one-dimensional equivalence partitioning, we need to consider each aspect of the ID requirement individually.

Length of the ID:

Valid partitions: 5 to 10 characters (1 partition)

Invalid partitions: Less than 5 characters, more than 10 characters (2 partitions)

Type of characters:

Valid partitions: Alphanumeric characters (1 partition)

Invalid partitions: Non-alphanumeric characters (1 partition)

Type of first character:

Valid partitions: First character is a letter (1 partition)

Invalid partitions: First character is not a letter (1 partition)

Adding these together, we have a total of 1 (valid length) + 2 (invalid lengths) + 1 (valid type) + 1 (invalid type) + 1 (valid first character) + 1 (invalid first character) = 7 partitions.

Planning poker is a consensus-based estimation technique used in Agile. It involves team members selecting cards with their estimate for a user story, then discussing the differences in estimates.

Option A:Incorrect. While three-point estimation is valid, planning poker focuses on team consensus rather than individual estimation techniques.

Option B:Incorrect. The goal of planning poker is not to force unanimity but to reach a reasonable consensus.

Option C:Incorrect. Averaging estimates is not how planning poker works.

Option D:Correct. The members with the highest and lowest estimates discuss their reasoning to foster understanding and adjust estimates accordingly in subsequent rounds.

A factor that contributes to a successful review is ensuring that all participants are trained to understand the review type and its objectives. This training helps participants to effectively contribute to the review process, identify issues, and suggest improvements. Proper training also fosters a constructive and collaborative review environment.

Checklist-based testing, as defined in the ISTQB CTFL syllabus, is indeed a review technique used within formal review processes. During these reviews, reviewers individually inspect work products to identify defects based on predefined checklists. These checklists serve as guidelines to ensure thorough examination and to cover important aspects consistently.

The other options do not accurately describe the checklist-based testing technique. Option A describes a technique for managing review meetings rather than the checklist-based testing itself. Option C incorrectly emphasizes the level of detail in checklists as a factor in reproducibility of test cases, which is not the primary focus of checklist-based testing. Option D, while true about the necessity of periodic review, is not the core aspect of the checklist-based testing technique itself.
