Google Cloud Professional Cloud Network Engineer — Question 21

Your company has recently expanded their EMEA-based operations into APAC. Globally distributed users report that their SMTP and IMAP services are slow.
Your company requires end-to-end encryption, but you do not have access to the SSL certificates.
Which Google Cloud load balancer should you use?

Answer options

• A. SSL proxy load balancer
• B. Network load balancer
• C. HTTPS load balancer
• D. TCP proxy load balancer

Correct answer: D

Explanation

The TCP proxy load balancer is the correct choice because it can handle non-SSL traffic and provide end-to-end encryption without needing direct access to SSL certificates. The SSL proxy load balancer and HTTPS load balancer are not suitable here as they require SSL certificates, while the Network load balancer does not provide the necessary encryption.
