JN0-232 Exam Dumps : Security, Associate (JNCIA-SEC)

Adding interfaces (Option A):An interface must be assigned to a security zone before it can pass traffic. By default, interfaces are in the null zone and cannot send or receive traffic.

Exception traffic (Option B):Security zones define host-inbound-traffic settings, which determine what types of management or control-plane traffic (SSH, ICMP, SNMP) are permitted.

Routing instances (Options C and D):Security zones arespecific to a routing instanceand cannot include interfaces from multiple instances. Therefore, interfaces in the same zone cannot belong to different routing instances.

Correct Statements:A and B

After confirming correct routing:

The next step is toverify security zone assignments (Option A). If interfaces are not correctly assigned to zones, traffic will not be evaluated against proper inter-zone or intra-zone security policies, causing drops.

Option B:The routing protocol is irrelevant once the correct route lookup is confirmed.

Option C:NAT is checked later in the flow, not the immediate next step after routing.

Option D:ALG is only needed for specific applications (FTP, SIP), not general troubleshooting.

Correct Next Step:Verify that interfaces are assigned to the correct security zones.

License Requirement (Option B):NextGen Web Filtering (NGWF) is a licensed feature on SRX devices. Without a license, the service cannot operate.

Local vs. Cloud Lists (Option C):NGWF checkslocal block/allow lists first. If the URL does not match locally, the request is then checked against the Juniper cloud database.

Option A:Incorrect, since the cloud is only consulted if the URL is not in the local list.

Option D:Incorrect, as NGWF requires a valid subscription/license.

Correct Statements:NGWF requires a license, and it checks local lists before cloud lookup.
