CCNA AI and Network Operations Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  Because HTTPS provides encrypted transport for sensitive API communication.

  Why this is correct

  HTTPS uses TLS to encrypt the entire HTTP conversation, ensuring that sensitive payloads like authentication tokens, personal data, or financial records cannot be read or tampered with in transit. This protects API communication from eavesdropping and man-in-the-middle attacks, which is the primary reason it is preferred for sensitive exchanges over unencrypted HTTP.

• ✗

  Because HTTPS provides better throughput for API responses

  Why it's wrong here

  HTTPS does not improve throughput; the TLS handshake adds round trips and encryption/decryption consumes CPU cycles, which can slightly reduce data transfer speed relative to plaintext HTTP. Its purpose is to provide confidentiality and integrity, not to accelerate API responses. Therefore, claiming better throughput is incorrect.

  When this WOULD be correct

  In a question focused on network management or configuration, where the context involves the automatic assignment of VLANs based on traffic types or protocols, this option could be correct if discussing a specific technology that integrates VLAN assignment with secure protocols.

• ✗

  Because HTTPS replaces the need for authentication.

  Why it's wrong here

  HTTPS only secures the communication channel between client and server; it does not verify the identity of the calling user or determine whether the caller is authorized to access the API. Authentication mechanisms, such as API keys, OAuth tokens, or mutual TLS, are still required separately. Relying solely on HTTPS would leave the API open to unauthorized access.

  When this WOULD be correct

  In a different exam scenario, a question might ask about the benefits of using HTTPS in a context where authentication methods are being discussed. If the question implied that HTTPS simplifies the authentication process by providing a secure channel, this option could be considered correct.

• ✗

  Because HTTPS is the only protocol that can carry JSON.

  Why it's wrong here

  JSON is a text-based data interchange format that can be transmitted over any transport protocol, including both HTTP and HTTPS. The encryption provided by HTTPS has no bearing on the protocol's ability to carry JSON; a plain HTTP request can equally include a JSON body. Thus, HTTPS is not the only protocol capable of carrying JSON.

  When this WOULD be correct

  In a question specifically asking about protocols that can transmit JSON data, where the context is limited to comparing HTTPS with other protocols that cannot carry JSON, this option could be correct. For example, a question might ask which protocol is exclusively used for JSON transmission, making D the right choice.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
