Juniper Updated JN0-232 Exam Questions and Answers by lily-may

Afeature profilein a UTM (Unified Threat Management) configuration defines how a specific UTM feature should operate. Examples include:

Anantivirus feature profilethat specifies the type of scanning to perform (streaming or full file-based).

Aweb filtering feature profilethat defines filtering methods, categories, and actions.

Anantispam profilethat defines how spam detection and actions are performed.

Feature profiles do not directly apply to traffic or policies. Instead, they arereferenced inside a UTM policy, and then that policy is applied to a security policy.

Therefore, a feature profile’s purpose is todefine the operation of a specific UTM feature.

When source NAT uses a pool of addresses from thesame subnet as the egress interface, the firewall must respond to ARP requests for those NAT pool IPs. Without this, upstream devices would not know how to forward traffic destined for those IPs.

Proxy ARPis required (Option D). It enables the SRX to answer ARP requests on behalf of the NAT pool addresses.

Static NAT (Option A)is unrelated and maps one-to-one, not required here.

Dynamic DNS (Option B)has no relation to NAT pools.

Destination NAT (Option C)applies to inbound translations, not outbound source NAT pools.

Correct Feature:Proxy ARP

NextGen Web Filtering (NGWF) requires SSL proxy functionality to inspect HTTPS traffic. To enable NGWF:

Option B:You can generate aself-signed certificatefor SSL proxy functionality (or import a CA-signed certificate, but the course emphasizes self-signed for lab/demo purposes).

Option D:You must configure anSSL proxy profileso 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

On high-end SRX platforms, control-plane (Routing Engine–destined) traffic transits the loopback (lo0) and is best captured by applying afirewall filter on lo0 with the then sample action, together withtraffic samplingunder forwarding-options to write packets to a file.

sample sends matched control-plane packets to the sampling process, which can record them for analysis.

datapath-debug capture focuses on data-plane/SPC paths and is not the tool for generic control-plane packet capture.

tcpdump from shell is not the supported workflow on SRX; the operational command is monitor traffic, but forhigh-endcontrol-plane capture, the recommended and scalable method islo0 filter + sampling.

Port mirroring mirrors transit data-plane traffic, not RE-destined control-plane packets.
