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

The antivirus feature on SRX relies on signature definition files that must be regularly updated. To check the status of these updates, the correct operational command is:

show security utm anti-virus status (Option D). This displays details such as:

Antivirus engine status

Last update time of virus definitions

Version of the signature database

Other options:

Content-filtering statistics (Option A) shows counters for file-type filtering, not antivirus updates.

Anti-spam status (Option B) shows spam filtering engine connectivity.

Web filtering status (Option C) shows SBL/web filter server connection details.

Correct Command: show security utm anti-virus status

SSH Access (Option B): Host-inbound-traffic controls traffic destined to the SRX device itself (management/control plane). If host-inbound-traffic is not configured to allow SSH, then SSH access to the firewall is blocked.

Explicit Zone Configuration (Option D): For user-defined security zones, host-inbound-traffic must be explicitly configured to allow specific services (SSH, ICMP, SNMP, etc.).

Console Access (Option A): Console access is not controlled by host-inbound-traffic. Console access is always available directly.

Management Zone (Option C): In the management functional zone, host-inbound-traffic is implicitly allowed for management services, so this is not explicitly required.

Correct Statements: B and D

For an SRX firewall interface to respond to management traffic such as ICMP pings:

The interface must be assigned to a security zone (Option A). If an interface is not part of any zone, it is placed into the null zone, which drops all traffic.

Additionally, the zone must be configured to allow management traffic types as host-inbound-traffic (Option D). For ICMP, the protocol must be explicitly allowed under host-inbound-traffic for that zone.

Other options:

Security policies (Option B) control traffic traversing the firewall, not traffic destined to the SRX device itself.

Assigning the interface to the null zone (Option C) prevents any communication, including management.

Correct Actions: Assign the interface to a zone and configure ICMP under host-inbound-traffic.
