The diagram lists various types of operating systems (LNX, W2K, WSP), databases (ORA, MSQ, SQL), and application servers (JBS, WSP) supported by the application under test. To test all possible combinations of these types, we need to multiply the number of options in each category. In this case, we have:

• 3 options for operating systems
• 3 options for databases
• 2 options for application servers

Therefore, we have 3 x 3 x 2 = 18 possible combinations to test.

However, if we look closely at the diagram, we can see that some combinations are not valid or feasible because they are not connected by lines. For example, we cannot test LNX with WSP as an application server because there is no line between them. Similarly, we cannot test W2K with JBS as an application server because there is no line between them. Therefore, we need to exclude these invalid combinations from our calculation.

If we count only the valid combinations that are connected by lines in the diagram, we get:

• 5 combinations for LNX (LNX-ORA-JBS, LNX-ORA-WSP, LNX-MSQ-JBS, LNX-MSQ-WSP, LNX-SQL-JBS)
• 5 combinations for W2K (W2K-ORA-WSP, W2K-MSQ-WSP, W2K-SQL-WSP)
• 5 combinations for WSP (WSP-ORA-JBS, WSP-ORA-WSP, WSP-MSQ-JBS, WSP-MSQ-WSP)

Therefore, we have 5 + 5 + 5 = 15 valid combinations to test.

A potential infinite loop is a type of defect that can be typically identified using static analysis by tools1. Static analysis is a technique that examines the source code or other software artifacts without executing them, and can detect defects, vulnerabilities, code smells, and deviations from standards early in the development process1. Static analysis tools are software tools that automate the static analysis technique and provide various features and functionalities to support it1. Static analysis tools can identify a potential infinite loop by analyzing the control flow and data flow of the source code and checking for conditions or statements that may cause an endless repetition or iteration1. A potential infinite loop can cause serious problems in software performance, functionality, reliability, and security1. Therefore, a potential infinite loop is a type of defect that can be typically identified using static analysis by tools.

Managing the incidents in a spreadsheet posted on the intranet is the best option for a QA manager of a start-up company who needs to implement within a week a low cost incident management tool. A spreadsheet is a simple and flexible tool that can be used to record, track, and report incidents. Posting the spreadsheet on the intranet can make it accessible and visible to the relevant stakeholders. This option can be implemented quickly and cheaply, without requiring much training or maintenance3 suggests this as follows:

A spreadsheet is a common tool that can be used for incident management, especially for small or simple projects. A spreadsheet can be used to create an incident report template that includes the necessary information and fields for each incident. The spreadsheet can also be used to sort, filter, group, or analyze the incidents based on various criteria. The spreadsheet can be shared or published on a network or web location that can be accessed by the project team and other stakeholders.

A, C, and D are not good options for a QA manager of a start-up company who needs to implement within a week a low cost incident management tool. Managing the incidents through E-mails and phone calls (A) is not a good option, as it can be inefficient, unreliable, and inconsistent. E-mails and phone calls can be easily lost, overlooked, or forgotten, and they do not provide a centralized or structured way of recording, tracking, or reporting incidents. Purchasing and deploying an incident management tool © is not a good option, as it can be expensive, time-consuming, and complex. An incident management tool may require licensing fees, installation costs, configuration efforts, training sessions, and maintenance support. Documenting incidents on a large board in the lab (D) is not a good option, as it can be impractical, insecure, and incomplete. A large board in the lab may not have enough space or structure to document all the incidents in detail, and it may not be accessible or visible to all the stakeholders. A large board in the lab may also expose confidential or sensitive information to unauthorized people.
