Juniper JN0-231 Exam Practice Questions (P. 3)

GPT-4o - Answer

The concept of global NAT address persistence primarily focuses on ensuring a consistent public IP address assignment for all sessions from a specific host. By implementing the persistent-nat feature, a stable and predictable IP mapping is maintained, which is crucial for applications sensitive to address variations, enhancing both connectivity stability and tracking simplicity. This is particularly useful in scenarios where external servers or applications require the recognition of returning clients based on IP addresses.

GPT-4o - Answer

For this task, Geo IP is indeed the way to go. This tool is perfect because it not only blocks traffic based on the geographic IP locations of senders but crucially also offers automatic updates as new IP addresses are allocated to different countries. This means your blocking stays accurate over time without needing manual adjustment. So, just set it up, and it’ll keep your network safety in check with minimal fuss.

GPT-4o - Answer

Absolutely! The correct statements regarding IKE security associations are that they are set up during Phase 1 negotiations and are inherently bidirectional. That means each end can establish, negotiate, and send information within the same security framework, enhancing communication reliability and efficiency. This bidirectionality is crucial for the dynamic environment of network security, where rapid updates in security parameters may be necessary.

GPT-4o - Answer

When setting up a NAT where you need specific one-to-one IP mappings without altering port numbers, you should opt for pool-based NAT without PAT. This method ensures each internal IP directly correlates to a unique external IP from a predefined pool. This setup is critical in situations where applications or services depend on consistent external IP representation, perfect for environments demanding predictability and simplicity in traffic routing and policy enforcement.
