HTTP Services

Which of the following statements are accurate about Server Name Indication (SNI)?

Choose two
  • A It supports transparent failover of TLS sessions from one web server to another.
  • B It allows multiple SSL/TLS secured virtual HTTP hosts to coexist on the same IP address.
  • C It enables HTTP servers to update the DNS of their virtual hosts' names using the X 509 certificates of the virtual hosts.
  • D It provides a list of available virtual hosts to the client during the TLS handshake.
  • E It submits the host name of the requested URL during the TLS handshake.
Explanation

SNI carries the requested server hostname in the TLS ClientHello. That lets a server select the correct certificate for the hostname and supports multiple SSL/TLS-secured virtual HTTP hosts at the same underlying IP address.
