NEW QUESTION # 35

Answer: C
NEW QUESTION # 36
A developer has a web server running with Node.js. The command to start the web server is node server.js. The web server started having
latency issues. Instead of a one second turnaround for web requests, the developer now sees a five second turnaround.
Which command can the web developer run to see what the module is doing during the latency period?
Answer: C
NEW QUESTION # 37
Refer to the code below:
01 let first = ' Who ' ;
02 let second = ' What ' ;
03 try {
04 try {
05 throw new Error( ' Sad trombone ' );
06 } catch (err) {
07 first = ' Why ' ;
08 throw err;
09 } finally {
10 second = ' When ' ;
11 }
12 } catch (err) {
13 second = ' Where ' ;
14 }
What are the values for first and second once the code executes?
Answer: A
Explanation:
Initial values:
* first = ' Who '
* second = ' What '
Execution:
Inner try/catch/finally:
* Line 05: throw new Error( ' Sad trombone ' );
* Control goes to the inner catch.
* Inner catch (lines 06-08):
catch (err) {
first = ' Why ' ;
throw err;
}
* first is set to ' Why ' .
* The error is rethrown.
* Inner finally (lines 09-11):
finally {
second = ' When ' ;
}
* finally runs whether or not there was an error.
* second becomes ' When ' .
After inner finally, the rethrown error continues to propagate to the outer catch.
Outer catch (lines 12-14):
} catch (err) {
second = ' Where ' ;
}
* Because the inner try rethrew, the outer catch runs.
* It sets second = ' Where ' .
Final values:
* first was changed to ' Why ' in the inner catch and never changed again.
* second became ' When ' in the inner finally, and then ' Where ' in the outer catch.
So:
* first is ' Why '
* second is ' Where '
Option B is correct.
Concepts: nested try/catch/finally, rethrowing errors, order of execution for catch vs finally, variable mutation through error propagation.
NEW QUESTION # 38
A developer is leading the creation of a new web server for their team that will fulfill API requests from an existing client. The team wants a web server that runs on Node.js, and they want to use the new web framework Minimalist.js. The lead developer wants to advocate for a more seasoned back-end framework that already has a community around it.
Which two frameworks could the lead developer advocate for?
Answer: B,C
Explanation:
The question is about:
* Web frameworks that run on Node.js
* Used to build servers and APIs
* With established communities.
From the given options:
* Angular:
* A front-end framework running in the browser, not a Node.js server framework.
* Gatsby:
* A React-based static site generator; uses Node tooling but is not primarily a Node server framework.
* Next / Next.js:
* Server-side rendering / full-stack frameworks built on Node.js and React.
* Used to create both server-rendered pages and APIs.
* They have active communities and are "seasoned" compared to a hypothetical Minimalist.js.
Although typical Node back-end frameworks would include Express.js, Koa, or NestJS, given the options provided, the best fits for server-side frameworks with Node.js and an ecosystem are:
* Next (interpreted as Next.js)
* Next.js
Thus, the correct pair from the list is B and D.
Concepts: Node.js web frameworks, server-side rendering, community-backed frameworks vs minimal/new frameworks.
