Question 170

A coding assistant must replace the implementation of one known function without disturbing adjacent logic. What file operation should it prefer?

  1. Delete and regenerate the repository's directory tree.
  2. Use a targeted Edit or patch, then inspect the diff and focused tests.
  3. Recreate the entire file using a generated replacement.
  4. Run a repository-wide text replacement of the function body fragment without checking exact callers and matching boundaries.

Explanation

Correct Answer

B:

Localized changes reduce accidental modifications elsewhere.

Incorrect Answers

A:

The request concerns only one function.

C:

Large rewrites risk deleting unrelated code.

D:

Broad textual replacement can alter similar but unrelated code. A scoped Edit against the known function and focused checks is safer.

Question 171

A test engineer needs a new, small fixture file in a known tests/fixtures directory. What operation should the agent use?

  1. Use Write for the new file after checking its target path and naming conventions.
  2. Use Edit on a nonexistent path without creating it.
  3. Overwrite a nearby production fixture as a shortcut.
  4. Run Grep and treat its output as a persisted fixture.

Explanation

Correct Answer

A:

Creating a new artifact differs from editing existing source.

Incorrect Answers

B:

Edit expects an existing target in typical file workflows.

C:

Destroying an existing artifact is unnecessary.

D:

Searching does not create the required file.

Question 172

A reviewer needs to execute an approved deterministic unit test for a changed function. Which tool choice is justified?

  1. Use Read on the test file and declare the suite passed.
  2. Run a destructive repository cleanup command first.
  3. Read the test file and treat its expected assertions as evidence the edited implementation passes.
  4. Run the narrowly scoped known test command through the permitted shell executor and inspect its actual result.

Explanation

Correct Answer

D:

A bounded test gives evidence of the edited behavior.

Incorrect Answers

A:

Reading code is not executing a test.

B:

Cleanup does not establish correctness of the function.

C:

A test description shows intended behavior, not execution outcome. A bounded test command must actually run to demonstrate a pass.

Question 173

A library maintainer must inspect exported symbols and find their callers before a rename. What search plan is most effective?

  1. Use only filename matching to infer every call site.
  2. Delete the named module from the proposed patch and use resulting test failures as the sole usage inventory.
  3. Rename all text in the repository before checking public exports.
  4. Read the module's exports and run targeted content search for references in the affected scope.

Explanation

Correct Answer

D:

Both declaration and usage evidence are required for a safe rename.

Incorrect Answers

A:

Symbol usages may occur in arbitrary files.

B:

Destructive experimentation is a poor substitute for searching references and exports. It also creates avoidable test noise and change risk.

C:

Blind edits may break unrelated identifiers.

Question 174

A developer joins an unfamiliar codebase and is asked to identify its configuration entry points. Select TWO early steps that avoid unnecessary context consumption while discovering an unfamiliar repository.

  1. Start changing settings based on common conventions.
  2. Open every configuration-looking file in the entire monorepo before narrowing the project scope.
  3. Run every package script to discover which one mentions configuration.
  4. Use Glob to inventory candidate configuration paths before opening files, rather than reading the whole repository.
  5. After the inventory, Grep for relevant configuration symbols within the candidate source directories, then read bounded matching content.

Explanation

Correct Answers

D:

Path inventory reduces the search area before any file contents enter context, protecting attention and token budget during repository discovery.

E:

Symbol-focused search further narrows which specific lines to inspect. This is distinct from the first step of locating file paths and avoids opening irrelevant configuration files.

Incorrect Answers

A:

Guessing risks altering the wrong file.

B:

Unbounded file reading consumes context and obscures the target. Discover candidate paths first, then inspect only relevant configuration entries.

C:

Executing unknown scripts is unsafe for simple discovery.

Question 175

A symbol search returns 6,000 matches including node_modules, but the requested code lives under src/. What adjustment should be made?

  1. Expand the search to the whole filesystem to be comprehensive.
  2. Delete dependency directories without checking the project.
  3. Copy all matches into a single prompt and expect the model to remember them.
  4. Narrow Grep to project source paths or exclusion filters, then inspect relevant matches.

Explanation

Correct Answer

D:

Scoped search improves signal and reduces context cost.

Incorrect Answers

A:

Broader noise makes the actual code harder to locate.

B:

Destructive changes are not needed for filtering.

C:

Large unfiltered results exceed useful reasoning context.

Question 176

A proposed auto-fix suggests running rm -rf against the repository root. The user asked only to inspect a failing test. What should the assistant do?

  1. Run the command because the model proposed it confidently.
  2. Hide the command output so the user is not alarmed.
  3. Refuse the destructive execution and use a bounded read/test inspection path consistent with the task.
  4. Execute as administrator to avoid permission errors.

Explanation

Correct Answer

C:

Read-only investigation does not justify deleting user data.

Incorrect Answers

A:

Confidence does not constitute authorization for irreversible deletion.

B:

Concealing a destructive action cannot make it safe.

D:

Higher privileges amplify unnecessary risk.

Question 177

A pull request modifies one condition in an existing module. The team wants a concise reviewable diff. Select TWO practices that keep this one-condition change reviewable and safe.

  1. Replace the whole file using an old cached snapshot.
  2. Regenerate every module in the package to keep formatting uniform.
  3. Apply a focused Edit to the condition and check only changed lines plus dependent tests.
  4. Disable version-control diff checks to save seconds.
  5. Compare the resulting diff against the intended behavior and inspect any changed interface assumptions before accepting it.

Explanation

Correct Answers

C:

A narrow patch preserves unrelated code and makes review straightforward.

E:

A focused edit limits the mechanical surface area; reviewing the behavioral delta helps detect a condition inversion or a dependency that unit tests did not cover.

Incorrect Answers

A:

Stale input can discard intervening edits.

B:

A broad rewrite obscures the actual change and may introduce regressions.

D:

The diff is critical evidence of what changed.

Question 178

A repository search finds a large compiled binary. The agent tries to inspect it with a text Read command and gets garbage. What is the better approach?

  1. Continue dumping binary bytes into the conversation until a pattern appears.
  2. Rewrite the binary as UTF-8 text to make it readable.
  3. Use metadata or an appropriate binary-aware tool and avoid treating binary bytes as source text.
  4. Assume it contains no code or useful metadata because Read failed.

Explanation

Correct Answer

C:

Text decoding cannot reliably reveal compiled artifact semantics.

Incorrect Answers

A:

Uninterpretable output wastes context.

B:

Changing encoding would corrupt the artifact.

D:

Text-read failure is not evidence about the file's contents.

Question 179

A CI runner returns a 200,000-line log, but only failures related to one test suite matter. What should the agent pass to its reasoning context?

  1. Pick the last line as the complete cause of all errors.
  2. Paste the complete log repeatedly at every subsequent turn.
  3. Persist the complete log externally and supply bounded, source-linked failure excerpts with relevant stack traces.
  4. Remove all stack traces and report only 'tests failed'.

Explanation

Correct Answer

C:

Focused evidence avoids flooding context while keeping full logs available.

Incorrect Answers

A:

The last line may be unrelated to the root failure.

B:

Repeated massive input obscures actionable failures.

D:

An unqualified status cannot support targeted fixes.

Question 180

A developer cannot find handleAuth because the search command uses case-sensitive matching and code spells it handleAUTH. What is the appropriate adjustment?

  1. Run a speculative code edit to force the symbol into existence.
  2. Rename every source file before searching again.
  3. Declare the function absent after one case-sensitive query.
  4. Use the supported content search tool's case-insensitive or appropriately configured matching, then inspect actual hits.

Explanation

Correct Answer

D:

Case-aware search finds variants without mutating source.

Incorrect Answers

A:

Creating new symbols is unrelated to locating the existing implementation.

B:

Filename changes do not solve symbol lookup.

C:

The result only shows that exact capitalization was not matched.
