Static NAT is bidirectional on SRX Series Firewalls. It creates a fixed one-to-one translation between an original address and a translated address, allowing sessions to be initiated from either side of the gateway. Destination NAT, by contrast, allows inbound access to internal resources but is not inherently bidirectional in the same way. Source NAT translates the source address for outbound connections, commonly allowing private hosts to access public networks, and return traffic is handled by the session table. Source NAT without PAT still does not provide the automatic reverse mapping behavior of static NAT. Juniper documentation notes that static NAT mappings allow connections to be established from either side, which makes static NAT the correct answer.

In Junos OS, traffic is classified into three main categories:

Transit traffic:

Defined as traffic that enters one interface and exits another interface .

It is handled entirely in the forwarding plane (Packet Forwarding Engine) .

Example: User data packets moving between trust and untrust zones.

Correct → Option A .

Exception traffic:

Traffic requiring processing by the Routing Engine (control plane) , such as routing updates or management traffic.

Matches Option C/D , but that is not transit traffic.

Control traffic:

Management or routing-related, handled by the control plane.

Rate-limiting (Option B):

This applies specifically to exception traffic to protect the Routing Engine, not to transit traffic.

Correct Statement: Transit traffic is traffic that is processed solely through the forwarding plane.

The correct command is show security utm web-filtering status. This operational mode command verifies whether the web-filtering service connection is up. For NGWF, the SRX sends URL or destination IP information to the Juniper NGWF cloud, where the URL is categorized and reputation information is returned to the device. Because NGWF depends on cloud connectivity, checking web-filtering status is the appropriate troubleshooting and verification step. The anti-spam and anti-virus status commands verify different Content Security services, and content-filtering statistics show content-filter counters rather than cloud web-filtering connectivity. Juniper documentation also notes that this command can confirm whether web filtering is down because of a missing license or service condition.
