Answer analysis

Option-by-option breakdown

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

• ✗

  The Wi-Fi adapter is faulty.

  Why it's wrong here

  A faulty Wi-Fi adapter typically manifests as an inability to detect any wireless networks, intermittent disconnections, or a complete failure to enable the Wi-Fi radio. If the tablet displays "Saved, secured," it indicates that the adapter successfully detected the network, authenticated with the access point using the saved credentials, and established a Layer 2 connection. Therefore, the adapter itself is likely functional, as it has progressed beyond the initial physical and data link layer connection failures associated with a hardware fault.

• ✓

  The tablet has a static IP address configured that conflicts with the network.

  Why this is correct

  If a tablet is manually configured with a static IP address that conflicts with the network's DHCP range, is already in use by another device, or is on a different subnet than the gateway, it will fail to establish proper network communication. The "Saved, secured" status confirms successful authentication with the access point (Layer 2), but the incorrect static IP prevents the device from communicating at the network layer (Layer 3). This scenario perfectly explains why a device is connected but cannot access network resources or the internet.

• ✗

  The corporate network requires a VPN profile that is missing.

  Why it's wrong here

  A missing VPN profile would not prevent an Android tablet from obtaining an IP address from the local Wi-Fi network. VPNs operate at a higher layer (typically Layer 3 or 4) than the initial Wi-Fi connection and IP address acquisition process. The device would still successfully connect to the access point, acquire an IP address via DHCP, and then attempt to establish the VPN tunnel. Failure to establish the VPN would prevent access to specific corporate resources, but not the fundamental ability to obtain a local IP address.

• ✗

  The tablet's MAC address is blocked by the router.

  Why it's wrong here

  MAC address filtering is a Layer 2 security mechanism that controls which devices are permitted to associate with an access point based on their unique hardware address. If the tablet's MAC address were blocked by the router or access point, it would be denied association with the Wi-Fi network entirely. Consequently, the tablet would not be able to reach the "Saved, secured" state, which signifies successful authentication and establishment of a Layer 2 connection.
