Oracle claims to support existing installations of RHEL for less. What should you tell customers to correct that perception?

$($Choose all correct answers$)$

When Oracle takes over support for RHEL, they add Oracle$-$compiled RHEL packages which invalidates third$-$party application vendor support in most cases

Only Red Hat has the resources and expertise to support RHEL

All RHEL security, hardware, and software certifications are null and void when running Oracle Linux

Mixing OS packages from multiple vendors is supported by Red Hat or its certified partners
