BCS TM12 Exam - Topic 7 Question 93 Discussion

Actual exam question for BCS's TM12 exam

Question #: 93
Topic #: 7

[All TM12 Questions]

Assume you are the Test Manager in charge of independent testing for avionics applications.

You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):

- a BOOT-X CSCI that must be certified at level B of the DO-178B standard

- a DIAG-X CSCI that must be certified at level C of the DO-178B standard

- a DRIV-X CSCI that must be certified at level A of the DO-178B standard

These are three different software modules written in C language to run on a specific hardware platform.

You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.

Since there are significant budget constraints to purchase this tool, you are evaluating an open-source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).

The source code of the tool is available.

Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.

Which of the following are the three main concerns related to that open-source tool selection?

Number of correct responses: 3

(2 credits out of 3 credits correct, 1 credit point)

ADoes the tool support all the types of code coverage required from the three levels A, B, C of the DO-178B standard?

BDoes the tool have a good general usability?

CWhat are the costs to qualify the tool as a verification tool under the DO-178B?

DIs the installation procedure of the tool easy?

EDoes the tool require a system with more than 4GB of RAM memory?

FIs the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?

What about the costs to qualify it? That's a big deal!

Definitely need to check if it supports all coverage types for A, B, C.

I vaguely recall that installation ease isn't as crucial as ensuring the tool supports the necessary code coverage types for certification.

I feel like we practiced a similar question about tool selection, and I think the licensing scheme could be a big issue for confidentiality in avionics.

I'm not entirely sure, but I think usability might be less critical than ensuring the tool meets all coverage requirements for levels A, B, and C.

I remember discussing the importance of tool qualification under DO-178B, so I think we should be concerned about the costs to qualify the tool as a verification tool.

Customizing the open-source tool sounds like a good option, but I'm worried about the time and effort that would take. We need to make sure the tool can be easily integrated into our existing processes.

The budget constraint is a big concern here. We'll need to carefully evaluate the costs of qualifying the open-source tool as a verification tool under DO-178B. That could get expensive.

I'm a bit confused about the different CSCI levels and how that impacts the code coverage requirements. I'll need to review the DO-178B standard more closely to make sure I understand the nuances.

This seems like a tricky question, but I think I can handle it. The key is to focus on the DO-178B certification requirements and how the open-source tool can meet them.

Okay, let me see here. I think I can narrow this down by eliminating the options that don't seem quite right.

I think this question is asking about a tool that can help identify security vulnerabilities in package dependencies. SonarQube seems like the most relevant option here, as it can analyze code and dependencies for known security issues.

I think the answer is D, the Internet. Threat intelligence tools need to constantly monitor and analyze data from various online sources to stay on top of the latest threats. Searching customer data or an internal database wouldn't give them the comprehensive view they need.

Okay, I've got this. The key is to focus on the first step, which is to address the material shortage causing the production shortfall. Moving the time fence or overstating the plan wouldn't directly resolve the shortage, so I'll go with B - move in the time fence.

RAM requirements? Seriously? I bet the developers spent more time debating emojis in the commit messages than optimizing memory usage. This is avionics, not Candy Crush.

The key concern here is whether the open-source tool can meet the coverage requirements for all three CSCI levels - A, B, and C. That's critical for compliance with DO-178B.
