Juniper JN0-232 Exam With Confidence Using Practice Dumps

Content filtering on SRX devices inspects and controls specific file types transferred across certain application protocols:

SMTP (Option A): Supported. Content filtering can block specific file attachments in emails.

HTTP (Option D): Supported. Content filtering can block downloads of specific file types over web traffic.

SNMP (Option B): Not supported; SNMP is a management protocol, not a content delivery protocol.

TFTP (Option C): Not supported by content filtering.

Correct Protocols: SMTP and HTTP

From the exhibit:

The user attempted to access

The block page indicates:

CATEGORY: NG_Reference

REASON: BY_PRE_DEFINED

The header states: “Juniper Web Filtering has been set to block this site.”

Analysis of options:

Option A: Correct. The log shows “REASON: BY_PRE_DEFINED,” which means the site was blocked because it matched a predefined category in the Web filtering database.

Option B: Correct. The category “NG_Reference” indicates that the NextGen (Enhanced/Cloud-based) Web Filtering type is being used.

Option C: Incorrect. The exhibit does not provide any information about SSL proxy configuration; it only shows that the HTTPS site was blocked.

Option D: Incorrect. The block page shown is the standard Juniper default block page, not a custom message.

Correct Statements: The URL matches a predefined Web filtering category, and the NextGen Web Filtering type is being used.

The exhibit shows the output of show security nat source rule source-NAT-rule-1. The rule belongs to the source NAT rule set and has rule position 1, so it is the first NAT rule in that rule set. The match section shows the source address range as 0.0.0.0 - 255.255.255.255, meaning any IPv4 source address matches. The rule also specifies traffic from the Trust zone to the Untrust zone. Therefore, all traffic entering through the Trust zone and leaving through the Untrust zone matches this source NAT rule. The output also shows translation hits and successful sessions, confirming that traffic has matched the rule. It is not limited to only traffic matching the default route. Juniper documents that NAT rule sets use source/destination zone or interface matching and can be verified with show security nat source rule.
