Which two features are supported in a virtual machine using Intel Software Guard Extensions (Intel SGX) technology?

The correct choice identifies VM encryption as being supported in a virtual machine using Intel Software Guard Extensions (Intel SGX) technology. Intel SGX is designed to enhance security by creating isolated execution environments called enclaves within the CPU that protect sensitive data and code from other processes, including those running in the same system. This capability provides a strong foundation for VM encryption because it secures the sensitive cryptographic keys and data during encryption operations, safeguarding them from unauthorized access.

VM encryption typically involves encrypting the virtual machine's virtual disks and configuration files to protect data at rest, while Intel SGX can enhance this by securely managing encryption keys within its protected enclaves. This combination ensures that even if the host system is compromised, the encrypted data remains secure.

In contrast, features like fault tolerance, storage I/O control, and virtual machine suspend and resume are more related to resource management and availability rather than direct security enhancements. While these features are important for general virtual machine operation and management, they do not specifically utilize or leverage the unique security capabilities offered by Intel SGX.
