NextGen Web Filtering (NGWF) requires SSL proxy functionality to inspect HTTPS traffic. To enable NGWF:
Option B: You can generate a self-signed certificate for SSL proxy functionality (or import a CA-signed certificate, but the course emphasizes self-signed for lab/demo purposes).
Option D: You must configure an SSL proxy profile so that HTTPS traffic can be decrypted and inspected.
Option A: A CA-signed certificate may be used in production but is not strictly required to enable NGWF.
Option C: SSL initiation profiles are used for outbound SSL inspection initiated by the SRX, not for NGWF traffic interception.
Correct Actions: Generate a self-signed certificate, Configure an SSL proxy profile

The session output shows traffic entering the SRX from 192.0.2.212/49862 to the public destination 203.0.113.199/22. The paired flow shows the translated internal server address as 10.10.101.10/22. This confirms destination NAT because the original destination IP address 203.0.113.199 is translated to the internal destination IP address 10.10.101.10. Juniper's destination NAT documentation shows the same interpretation of show security flow session: the incoming flow is destined to the public address, while the paired flow displays the translated private destination address. PAT is not being performed because the destination port remains 22 before and after translation. PAT would require port translation, but no port number changes are shown.

A feature profile in a UTM (Unified Threat Management) configuration defines how a specific UTM feature should operate. Examples include:
An antivirus feature profile that specifies the type of scanning to perform (streaming or full file-based).
A web filtering feature profile that defines filtering methods, categories, and actions.
An antispam profile that defines how spam detection and actions are performed.
Feature profiles do not directly apply to traffic or policies. Instead, they are referenced inside a UTM policy, and then that policy is applied to a security policy.
Therefore, a feature profile's purpose is to define the operation of a specific UTM feature.

Functional zones (e.g., junos-host, management, null) are not used for forwarding transit traffic. They are used to manage traffic destined to or from the SRX device itself.
Option A: Correct. If traffic enters through a functional zone interface, it is meant for the SRX, not for transit, so it cannot exit another interface.
Option D: Correct. Transit interfaces handle forwarding traffic, but they cannot send that traffic out through a functional zone interface.
Option B and C: Incorrect, because functional zones are strictly control-plane, not transit forwarding zones.
Correct Statements: A and D

When a packet enters an SRX interface, a route lookup is performed:
It determines the egress interface (Option B) by checking the destination IP against the routing table.
Once the egress interface is known, its associated egress security zone (Option D) is also determined.
The ingress interface (Option A) is already known when the packet arrives, so the route lookup does not determine it.
DNS name (Option C): DNS is unrelated to routing lookups.
Correct Results: egress interface, egress security zone
