Front End Development Risk Assessment & Management 2

Question 1

A third-party npm package your front-end relies on is found to have a critical XSS vulnerability. What is the FIRST action you should take?

Accepted Answer

Check if a patched version exists and upgrade immediately

Answer

Upgrading to a patched release is the fastest way to close the known vulnerability while preserving functionality.

Question 2

Which metric best quantifies the potential financial impact of a risk event when performing a quantitative risk assessment?

Accepted Answer

Expected Monetary Value (EMV)

Answer

EMV multiplies the probability of a risk by its monetary impact to produce a single comparable figure.

Question 3

A feature toggle (feature flag) system can reduce front-end deployment risk primarily by:

Accepted Answer

Allowing instant rollback of a feature without redeployment

Answer

Feature flags let teams disable a problematic feature server-side instantly, eliminating the need for an emergency redeploy.

Question 4

You discover that 40% of your users are on slow 3G connections and your bundle is 4 MB. What risk does this pose?

Accepted Answer

Performance risk leading to high bounce rates and revenue loss

Answer

A 4 MB bundle on 3G can take 10+ seconds to load, causing users to abandon the page before it becomes interactive.

Question 5

Which risk mitigation strategy is applied when a team decides to use a well-tested UI component library instead of building custom components from scratch?

Accepted Answer

Risk reduction

Answer

Using a battle-tested library reduces the probability of introducing bugs compared to untested custom code.
