Read the first 6 ACS Apple Networking & Connectivity flashcards as text

  1. What Bluetooth version do iPhone 15 models support, and what improvement does it offer over previous versions?

    Answer: Bluetooth 5.3 with improved coexistence and lower power

    iPhone 15 models support Bluetooth 5.3, which improves coexistence with other wireless signals, enhances connection reliability, and reduces power consumption.

  2. What does 'Private Wi-Fi Address' do on iPhone when connecting to Wi-Fi networks?

    Answer: Uses a randomized MAC address per network to prevent tracking across different networks

    Private Wi-Fi Address assigns a unique, randomized MAC address for each Wi-Fi network the iPhone joins, preventing third parties from tracking the device across networks.

  3. Which protocol does iPhone use for eSIM provisioning, allowing carriers to activate a SIM remotely without a physical card?

    Answer: GSMA RSP (Remote SIM Provisioning)

    eSIM on iPhone uses GSMA's Remote SIM Provisioning (RSP) standard, which allows carriers to deliver and activate a SIM profile over the internet without a physical card.

  4. What should an ACS specialist check first when a customer reports that their iPhone won't connect to a specific Wi-Fi network?

    Answer: Forget the network and reconnect, then check router settings and IP configuration

    Starting with 'Forget This Network' and reconnecting resolves most Wi-Fi issues; if that fails, checking IP configuration and router compatibility follows before hardware assessment.

  5. What is 'iCloud Private Relay' and which Apple subscription includes it?

    Answer: A privacy feature that routes Safari traffic through two servers to hide IP, included in iCloud+

    iCloud Private Relay routes Safari browsing through Apple and a third-party server so neither knows both the user's identity and what they're visiting; it's included with iCloud+ plans.

  6. Which port does Apple use for its AirPlay protocol for wireless audio and video streaming from iPhone to Apple TV or speakers?

    Answer: TCP/UDP port 7000 and related ports

    AirPlay primarily uses TCP port 7000 (and additional ports for specific functions) for device communication, with Bonjour (port 5353) for device discovery.
