Question 480
The organization plans to rely on GRE tunnel. Which caveat should the engineer document before deployment?
Explanation
Correct Answer
The limitation applies directly to GRE tunnel: GRE alone does not encrypt an untrusted transport path. Without considering that boundary, success for forward office traffic to a cloud security service when the edge supports GRE and the design permits it can be overstated.
Incorrect Answers
For IPsec tunnel, an established IKE negotiation alone does not prove traffic selectors and routing are correct. It is not the specific constraint the reviewer needs to assess for GRE tunnel.
For Z-Tunnel forwarding, A PAC-only mode may not capture traffic outside proxy-aware protocols. It is not the specific constraint the reviewer needs to assess for GRE tunnel.
For PAC file forwarding, PAC files do not control every non-proxy-aware application or all UDP traffic. It is not the specific constraint the reviewer needs to assess for GRE tunnel.
