Anthropic CCA-F Exam Dumps, Practice Test Questions

Creating billing records just to read reference material reintroduces a side effect that a catalog should not have. The problem is stale cached content, not missing ability to mutate business state. Retain a read-only resource and track content versions or update events to refresh clients safely.

Infrequent changes are still changes, and the case states a published update has already occurred. An indefinite cache would continue to show old instructions as current. A supported freshness policy or change notification must make the client invalidate its former version before relying on it.

Renaming a locally cached item does not alter its content or prove it represents the publisher’s latest revision. The important identity is the resource and its verified version. A client should refresh and validate the updated resource rather than cosmetically altering a stale title.

Clearing dialogue state cannot force an MCP resource cache to fetch a newer body if the caching policy still accepts the old version. It also loses unrelated context. Resource change notification or explicit version-aware refresh solves the actual stale-template problem.

Project-scoped configuration ensures teams use a common server endpoint but does not guarantee they run compatible client SDK/protocol versions or validate the same result schema.

Ignoring untrusted remediation text is crucial for prompt-injection defense; it cannot resolve shape drift introduced by different SDK versions on otherwise valid tool calls.

Narrowing integration visibility controls which users or projects can access it, but authorized users may still receive incompatible object shapes when their SDKs diverge.

Tenant authentication inside the server protects against cross-customer data access, but a globally registered connector can still appear in every agent’s tool menu and invite confusion or unnecessary calls.

A project-shared configuration is suitable only if the project is the correct authorized boundary. Putting the same customer-specific connector into every project configuration would retain the overbroad exposure.

Distinguishing connection failure from an empty catalog is useful in troubleshooting, but the catalog is improperly visible globally. Availability diagnostics do not fix the scope.

Better tool metadata improves selection but does not protect against malicious instructions appearing inside a legitimate-looking tool result after invocation.

Tool discovery errors and an empty catalog are separate operational states; neither addresses the prompt-injection content being returned by a connected MCP server.

Tenant authentication restricts data access inside a service, but it does not ensure Claude rejects malicious language in authorized tool output. An attacker may inject content into an otherwise accessible resource.

Model-output trust boundaries matter after a server returns data, but here the MCP transport never initialized. Rejecting malicious output does not tell the user whether capability discovery succeeded. The client must represent initialization failure as an error rather than the valid but empty list of tools.

Namespaces can distinguish similarly named tools across multiple healthy servers, but there are no valid tool descriptions to disambiguate until the crashed MCP process is recovered. Renaming capabilities cannot fix a transport initialization failure. The orchestration layer should surface that failure explicitly.

Clear tool metadata improves tool selection once tools/list is available. In this case the server dies before initialization completes, so the client has no reliable catalog to interpret. The correct safeguard is to preserve the error state rather than claiming an empty supported-tool set.

Separating read resources from mutating tools reduces permission mistakes after the server is connected. It cannot establish whether a crashed server supports tools at all. An accurate status must distinguish failed setup from a successful connection returning zero tools.

MCP resources are useful for passive reference content, but choosing resource versus tool does not repair failure during connection setup. The agent still needs a truthful indicator that discovery never finished. A successful empty catalog is a different state from a failed initialization.

Offering a catalog as a resource gives clients a clean way to list and read it, but the question also asks for a write-enabled editor under the same server. A resource declaration alone does not define who may edit documents or how write calls are authorized. Separate the editor as a controlled tool with enforced privileges.

Tenant authorization is essential for both read and write requests, but a single server-wide allow decision can still expose an edit action to read-only users. The design must distinguish the semantics and permissions of a catalog lookup from a document mutation. Enforce the relevant decision per operation.

Converting reference content to an MCP resource is appropriate for the read-only portion, yet that proposal does not specify an editing tool or prevent unauthorized writes. The actual architecture contains two different access modes that need distinct contracts. Pair passive resources with scoped, controlled mutation tools.

Clear namespaces and descriptions reduce accidental selection of the wrong backend tool, but tool naming is not a permission boundary. A malicious or mistaken call could still edit a document if the server does not enforce rights. Split catalog and editor contracts and validate write authority in the handler.

Schema/version compatibility makes protocol exchanges reliable, but a malicious URL can be perfectly valid data in a well-formed tool result. Type validation alone cannot authenticate a requested admin action.

Checking the transport command detects missing executables or runtime dependencies; it does not establish whether a URL returned by a malicious remote server is safe.

Project-scoped configuration limits exposure of local integrations but cannot authenticate an external server’s new remediation message. The attack takes place at the content/trust boundary after communication succeeds.

Project scope makes the server definition visible to the team, which is useful for reproducibility, but does not identify the bytes executed by an unpinned package command. Every engineer may still run a different or compromised release. The missing safeguard is reviewable executable provenance and an approved version boundary.

Separate service credentials constrain what a stolen token can do, but they do not protect the developer machine from code executed when an arbitrary updated MCP server starts. The newly downloaded package could still run malicious initialization logic before any API authentication. Pinning and verifying its origin addresses the supply-chain change.

Detailed logs might help reconstruct which package ran, but their creation occurs after the unreviewed executable has already started. An attacker-controlled update could access local files or credentials at initialization. Logging is detective evidence, not a substitute for a verified, pinned startup artifact and controlled upgrade process.

Quoting a path is important when passing it to a shell, but the case does not report a path-escaping problem. A correctly quoted path is still not evidence that the code was inspected before editing.

Bash is appropriate for running tests after a change; it does not replace inspection of the source line that needs patching and may introduce needless command execution before a simple read.

Glob discovers file paths, not the contents of a known small file. Pattern searching adds an unnecessary discovery step and does not establish the precise line to change.

Regenerating the entire module may alter imports, comments and unrelated code despite finding the correct function name. The request is limited to one implementation. An exact context-anchored Edit preserves unaffected code and should fail cleanly if the function body has changed since inspection.

Matching only a name can affect a call site or comment rather than the intended implementation, and it provides no check that the source has not changed. A targeted Edit against the expected original body is safer when the rest of the module must remain intact.

Path parsing errors should not turn a targeted read into a different command or file. The stated situation is that a code agent must replace one function implementation while preserving the rest of its module. Scoped edits minimize unrelated drift and ease verification. The alternative would pass the exact quoted path to a safe read operation, but the implementation still must use Edit or an exact targeted file-edit operation instead of rewriting the whole file to correct that specific failure.

Reading an existing file provides context but cannot create the required new configuration artifact. A quoted read path helps avoid shell mistakes, yet there is no file to read at the requested destination. The operation must be an authorized creation with validated content.

An anchored Edit replaces text in an existing document, which the scenario says does not yet exist. Attempting Edit against a new path may fail or act on the wrong file. Use a controlled creation operation rather than pretending the artifact is an edit.

A filesystem move is suitable when an existing source artifact should change location. The task instead requires creating a genuinely new configuration file from approved content. Moving an unrelated file could destroy its original location and still fail to produce the intended configuration.

Filename globbing can reveal whether a proposed configuration path collides with another artifact, but it performs no file creation. Once path safety is established, Write the approved bytes and verify the result. Discovery is a preliminary check, not the required operation.
