Shown solved, with the whole explanation open: this is what every question here carries.

3-3Ensuring the successful operation of a cloud solution

An engineer writes a single VPC firewall rule meant to cover traffic entering and leaving a VM. What does one rule allow?

Both directions in one ruleA single rule cannot span the two directions.
Direction inferred from portsPorts narrow a rule rather than orienting it.
Direction chosen per targetTargets select which instances a rule reaches.
One direction only per ruleCorrect · your answerCorrect. Two rules are needed for both.

Correct.

Concept

A packet filter that lets one entry answer several questions at once becomes impossible to audit, because nobody can say what any single line permits. Narrow entries are what make a rule set reviewable.

Why D

Each VPC firewall rule applies to incoming connections or to outgoing connections, never to both. Covering both needs two rules.
