CX Switches come with trusted platform modules (TPM). What is the function of TPM?

Question

Options

• ATPM stores a certificate signed by an HPE Aruba Networking Certification Authority (CA).
• BTPM prevents customers from loading certificates signed by the CA of their choice to the switches
• CTPM is just a convenient name to allow users to connect to the switch securely
• DTPM stores a certificate signed by GeoTrust Certification Authority (CA).

• A
  86% (37)
• B
  2% (1)
• C
  2% (1)
• D
  9% (4)

Explanation

Option A is correct because a Trusted Platform Module (TPM) is a dedicated hardware security chip that securely stores cryptographic keys and certificates - on HPE Aruba CX Switches, it holds a device identity certificate signed by HPE Aruba Networking's own Certificate Authority, enabling hardware-level authentication and supply chain integrity verification.

Option B is wrong because TPM doesn't restrict what certificates customers can load; it specifically stores the factory-provisioned HPE Aruba CA-signed certificate for device identity, not a customer access control mechanism.

Option C is wrong because TPM is not just a name or a user-facing login feature - it's a physical hardware component (defined by the TCG standard) with a specific cryptographic purpose, not a connectivity convenience label.

Option D is wrong because GeoTrust is a public commercial CA used for general TLS/SSL certificates; HPE Aruba uses its own internal CA to sign TPM device identity certificates, ensuring only genuine HPE Aruba hardware holds valid certificates.

Memory tip: Think of TPM as a tamper-proof ID badge baked into the hardware at the factory - the badge is issued and signed by the manufacturer's own CA (HPE Aruba), not a third-party commercial one.
