Blue Coat Proxy Practice Exam

The choice to select "Detect Protocol" for the Explicit HTTP service to handle SSL traffic is based on its capability to identify and manage the types of protocols being used over the connection. When SSL traffic is encountered, it is essential to properly detect and manage it to ensure that the proxy can apply the appropriate rules, security policies, and content filtering.

By selecting "Detect Protocol," the proxy can automatically identify SSL-encrypted traffic as it aims to handle HTTP and HTTPS requests correctly. This allows the service to perform actions such as decryption, traffic inspection, or policy application based on the detected protocol. This capability is crucial in environments where SSL is commonly used to protect sensitive communications.

Other options like "Enable Security" and "Require Encryption" do not specifically imply the ability to manage SSL traffic through protocol detection, and while "Allow SSL passthrough" might suggest handling SSL traffic, it indicates that it would not interfere with the encrypted traffic at all. Thus, protocol detection is the most appropriate function for enabling the management of SSL traffic within this context.
