Juniper JN0-336 Dumps Questions Answers

The correct answers are B and C. In Junos route-based IPsec VPNs, the default proxy ID is broad: local 0.0.0.0/0, remote 0.0.0.0/0, and service any. This default behavior allows routed traffic entering the secure tunnel interface to determine what is protected by the VPN rather than requiring a narrow policy-based encryption domain. Juniper’s IPsec VPN configuration guidance also states that proxy IDs are used in Phase 2 negotiations, and that a proxy ID mismatch is one of the common causes of Phase 2 failure. For interoperability with some third-party VPN peers, Juniper notes that proxy IDs may need to be manually configured to match the peer.

Option A is wrong because proxy IDs can override default route-based behavior when manually configured, especially when a peer requires specific local and remote protected subnets. Option D is wrong because proxy IDs are not created during IKE Phase 1. Phase 1 builds the secure IKE channel; proxy IDs belong to Phase 2/IPsec SA negotiation, where the peers agree on traffic selectors for encrypted traffic.

The correct answers are A and C. Juniper ATP Cloud uses a malware-analysis pipeline. When a file is submitted, the first step is a cache lookup based on the file hash. Juniper explains that if the file has already been analyzed, the stored verdict is returned to the SRX Series Firewall and there is no need to re-analyze the file. That directly supports C and eliminates B, because analysis does not continue when a cached verdict is found.

If the cache lookup does not return a verdict, the remaining ATP Cloud analysis techniques are used. Juniper describes the pipeline model in which each analysis technique creates a verdict number, and those verdicts are combined into a final verdict score from 0 to 10. That final threat score is what the SRX compares against ATP Cloud policy settings to permit or block the session.

Option D is wrong because ATP Cloud does not simply return the first score generated by any one feature. The expected behavior is cumulative/final scoring across the remaining analysis pipeline.

The correct answers are B and D. On SRX Series Firewalls, SSL proxy is configured by creating an SSL proxy profile and then applying that profile to the relevant security policy as an application service. Juniper’s SSL proxy configuration overview lists the required workflow: configure certificates and CA profile material, configure the SSL proxy profile, create a security policy matching the traffic to be inspected, and apply the SSL proxy profile to that security policy. Juniper further states that SSL proxy is enabled as an application service within a security policy, where the policy match criteria identify the traffic and the SSL proxy profile is applied to that traffic.

Option A is wrong because enabling the SSL ALG is not the required control point for SSL proxy. SSL proxy is a decryption/inspection service applied through policy, not simply an ALG toggle. Option C is wrong because creating a separate SSL application object is not the mandatory SSL proxy configuration action. The policy can match the desired traffic and then invoke SSL proxy through then permit application-services ssl-proxy profile-name. Juniper’s example explicitly shows applying the SSL proxy profile under the security policy action.
