In a Monolithic application, what issue can arise due to multiple applications being dependent on the same library?

• A. All applications upgrade together
• B. Changing the library version for one application might negatively affect the other
• C. No cross-app effects
• D. Each app uses a different runtime

Answer: (B)

In a monolithic setup, several parts of the application share the same library dependencies, all deployed as one unit. Because those components rely on the same library version, changing that library for one part can ripple through the others. If the library introduces a breaking change or modifies a behavior, other modules that expected the old API or behavior may fail or behave incorrectly, even though they didn’t directly request the change. That shared dependency coupling makes updates risky across the entire monolith, so a change to the library for one area might negatively affect the rest. The other options don’t capture this cross-component ripple effect: upgrading all parts together can happen in a monolith but isn’t the specific issue described; and cross-app effects and separate runtimes aren’t characteristic of the typical monolithic model.
