A user has configured ELB with SSL using a security policy for secure negotiation between the client and load balancer. The ELB security policy supports various ciphers. Which of the below mentioned options helps identify the matching cipher at the client side to the ELB cipher list when client is requesting ELB DNS over SSL?

  • Cipher Protocol
  • Client Configuration Preference
  • Server Order Preference
  • Load Balancer Preference
Explanation:
Elastic Load Balancing uses a Secure Socket Layer (SSL. negotiation configuration which is known as a Security Policy. It is used to negotiate the SSL connections between a client and the load balancer. When client is requesting ELB DNS over SSL and if the load balancer is configured to support the Server Order Preference, then the load balancer gets to select the first cipher in its list that matches any one of the ciphers in the client’s list. Server Order Preference ensures that the load balancer determines which cipher is used for the SSL connection.
