A systems administrator has migrated an internal application to a public cloud.
The new web server is running under a TLS connection and has the same TLS certificate as the internal application that is deployed.
However, the IT department reports that only internal users who are using new versions of the OSs are able to load the application home page.
Which of the following is the MOST likely cause of the issue?

A. B. C. D.C.
The most likely cause of the issue is option C, which states that the cloud web server is using a self-signed certificate that is not supported by older browsers.
A TLS (Transport Layer Security) connection is used to secure data in transit over the internet, and it relies on the use of digital certificates to establish trust between the client and server. When a user tries to connect to a website over TLS, the browser checks the certificate to make sure that it is issued by a trusted authority and that it matches the domain name of the website.
In this case, the systems administrator has migrated an internal application to a public cloud and has configured the web server to use a TLS connection with the same TLS certificate as the internal application. However, the IT department reports that only internal users who are using new versions of the OSs are able to load the application home page.
This suggests that older browsers or operating systems are not able to establish a secure connection with the cloud web server. One possible reason for this is that the web server is using a self-signed certificate that is not supported by older browsers.
A self-signed certificate is a digital certificate that is signed by the same entity that issues it, rather than a trusted third-party certificate authority. While self-signed certificates can be used for testing and development purposes, they are not suitable for production use as they do not provide the same level of trust as certificates issued by trusted authorities.
Older browsers and operating systems may not recognize or trust self-signed certificates, which can result in connection errors or security warnings. This can prevent users from accessing the application home page.
Therefore, option C is the most likely cause of the issue, as the cloud web server is using a self-signed certificate that is not supported by older browsers. The other options (A, B, and D) are less likely to be the cause of the issue as they do not directly relate to the use of TLS certificates. However, they could be potential causes if there are other configuration or network issues involved.
