A developer creates a new application, but the application must be tested before being released to a customer. When a mobile phone that uses 4G is used to access the application, the request fails…

Question

Options

• AThe application is hosted on premises and VPN connectivity is required
• BThe application must be added to the production server before testing.
• CThe application must be moved to the cloud before testing is possible.
• DThe application connectivity is limited to HTTPS protocol.

• A
  72% (36)
• B
  8% (4)
• C
  16% (8)
• D
  4% (2)

Explanation

When an application is hosted on-premises (within a corporate network), it sits behind firewalls and is not directly accessible from the public internet or cellular networks like 4G. A VPN (Virtual Private Network) is required to create a secure tunnel from the external device (the 4G phone) into the corporate network to reach the on-premises application. This is a common testing scenario where developers forget that on-premises apps are not publicly reachable. Options B and C are incorrect because testing does not require moving an app to production or the cloud. Option D is incorrect because HTTPS is a standard protocol supported over 4G.
