Free Zscaler ZDTA Actual Exam Questions - Question 2 Discussion

D imo, HTTP Connect tunnels work well in restrictive network environments where other protocols might be blocked. It could be the fallback or main method depending on the config.

C for sure, dTLS/TLS is designed for secure, efficient tunneling in Tunnel 2.0.

It’s C since Tunnel 2.0 prioritizes secure, low-latency tunnels like dTLS over older methods.

It’s C since Tunnel 2.0 focuses on modern encrypted tunnels, and dTLS/TLS offers lower latency than IPSec or GRE, which are older and less flexible for this use case.

C/D. Main transport is definitely dTLS/TLS for better encryption and efficiency, while HTTP Connect serves as a fallback on restricted networks. GRE and IPSec don’t fit typical Tunnel 2.0 setups here.

C/D? The main tunnel is dTLS/TLS for encryption and performance, but HTTP Connect can be used as a fallback on restrictive networks. So the primary method is definitely C, with D as backup.

It’s C because dTLS/TLS is designed for secure, reliable client-to-cloud tunnels here.

I’m thinking options A and B can be dropped since GRE and IPSec are less common for client-side tunnels here. D feels like a fallback method, so C seems like the main protocol. Could there be scenarios where D is preferred though?

Yeah, I’m thinking C too. GRE tunnels (A) don’t really fit because they don’t encrypt, which is a big no for Zero Trust. IPSec (B) is strong but usually for site-to-site, not client connectors. HTTP Connect (D) feels more like a fallback method when other tunnels can’t be established. So dTLS/TLS (C) seems like the main protocol used for secure, efficient traffic forwarding in Tunnel 2.0.

C. Tunnel 2.0 aims for secure, low-latency connections, which dTLS/TLS provides better than IPSec or GRE; HTTP Connect is more of a last resort, so it’s mainly about dTLS/TLS by design.

C for sure, since dTLS/TLS is designed exactly for this client-to-cloud secure tunnel.

B imo, IPSec tunnels are widely used for secure site-to-site connections and might be considered for robust encryption, even if dTLS/TLS is common. GRE tunnels (A) seem less likely since they offer no encryption.

C/D? I agree that dTLS/TLS (C) is the main method since Tunnel 2.0 focuses on secure, lightweight encryption. But the presence of HTTP Connect (D) as a fallback can’t be totally ignored—it’s usually triggered in environments where dTLS is blocked or restricted. Since the question doesn’t specify fallback scenarios explicitly, I’d go with C as the primary transport, but keep D in mind as a backup under certain network conditions. A and B seem outdated for Tunnel 2.0’s design.

C imo, dTLS/TLS fits Tunnel 2.0’s secure, modern approach better than IPSec or GRE.

It’s C because Tunnel 2.0 is designed around using dTLS/TLS tunnels for encapsulating traffic, which offers both security and performance benefits compared to GRE or IPSec. GRE and IPSec are more traditional, but Zscaler moved away from those to reduce overhead and improve connection stability. HTTP Connect (D) doesn’t really fit here since it’s more about proxying rather than tunneling at this layer. So, the key is that Tunnel 2.0 focuses on modern secure transport protocols, making dTLS/TLS the right choice.

C makes the most sense here since Tunnel 2.0 uses dTLS/TLS for secure, reliable transport. Options A and B are older or different methods.
