Question #: 8
Topic #: 1

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You use Azure Pipelines to build and test a React js application.

You have a pipeline that has a single job.

You discover that installing JavaScript packages from npm takes approximately five minutes each time you run the pipeline.

You need to recommend a solution to reduce the pipeline execution time.

Solution: You recommend enabling parallel jobs for the pipeline.

Does this meet the goal?

AYes

BNo

Show Suggested Answer

Suggested Answer: B

Instead enable pipeline caching.

Note:

npm-cache is a command line utility that caches dependencies installed via npm, bower, jspm and composer.

It is useful for build processes that run [npm|bower|composer|jspm] install every time as part of their build process. Since dependencies don't change often, this often means slower build times. npm-cache helps alleviate this problem by caching previously installed dependencies on the build machine.

Nope, just speeds up different tasks, not npm installs.

I thought parallel jobs could help with overall execution time?

Enabling parallel jobs won't speed up npm installs.

I vaguely recall something about optimizing the pipeline by using a cache task for npm. I wonder if that’s what we should be focusing on instead of parallel jobs.

I’m a bit confused. Wouldn’t caching the npm packages be a better solution? I feel like that could really cut down the time.

I think enabling parallel jobs might not help with the npm install time since it's a single job. I feel like I saw a similar question about caching dependencies.

I remember reading that parallel jobs can help with running multiple tasks at once, but I'm not sure if it specifically speeds up npm installs.

This looks like a question on performance measures. I think the key is to identify which measure includes both profits and the investment base. Residual income seems like the most likely answer, since it takes into account the cost of capital and the investment base.

Okay, I've got this. The two primary elements are fixed pay, like a salary, and variable pay, like bonuses or commissions. I'm confident that A is the right answer here.

This question seems straightforward - I think the answer is C, applying a risk-based approach to determine major programs.

I think the vBond orchestrator manages connections with vSmart controllers, but I'm not completely sure which option it is.
