Answer : B, C

Content filtering on SRX Series Firewalls is part of Juniper Content Security, but Juniper documentation states that content filtering does not require a separate license. Content filtering provides basic data loss prevention by filtering traffic based on MIME type, file extension, and protocol commands. Therefore, option C is correct because no separate content filtering license is required, and option B is correct because file extension is one of the supported filtering attributes. Option A is incorrect because it directly contradicts Juniper's content filtering documentation. Option D is not the best answer because content filtering is not described as full file-content inspection for determining file type; deeper inspection functions are associated with other Content Security services such as antivirus and AppID-based inspection.

Answer : B, D

Inbound Flow (before NAT):

Source = 10.20.30.40 (internal private IP)

Destination = 203.0.113.1 (public DNS server)

Outbound Flow (after NAT):

Source = 192.0.2.1 (translated IP)

Destination = 203.0.113.1 (unchanged)

Analysis:

The source IP (10.20.30.40) was translated to 192.0.2.1. This indicates Source NAT was applied Option B is correct.

The destination IP changed between the inbound and outbound view. Inbound it was 203.0.113.1, and outbound it is still 203.0.113.1 in appearance, but notice the reversal: the session entry shows it as the outbound 'source' side. This confirms Destination NAT translation has occurred for return flow consistency Option D is correct.

Option A: Incorrect. The original source IP was indeed translated.

Option C: Incorrect. The destination IP did change in the flow processing.

Correct Statements:

The original source IP address was translated to a new source IP address.

The original destination IP address was translated to a new destination IP address.

Answer : A, D

Functional zones (e.g., junos-host, management, null) are not used for forwarding transit traffic. They are used to manage traffic destined to or from the SRX device itself.

Option A: Correct. If traffic enters through a functional zone interface, it is meant for the SRX, not for transit, so it cannot exit another interface.

Option D: Correct. Transit interfaces handle forwarding traffic, but they cannot send that traffic out through a functional zone interface.

Option B and C: Incorrect, because functional zones are strictly control-plane, not transit forwarding zones.

Correct Statements: A and D

Answer : B, D

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

Answer : A, C

The session output shows traffic entering the SRX from 192.0.2.212/49862 to the public destination 203.0.113.199/22. The paired flow shows the translated internal server address as 10.10.101.10/22. This confirms destination NAT because the original destination IP address 203.0.113.199 is translated to the internal destination IP address 10.10.101.10. Juniper's destination NAT documentation shows the same interpretation of show security flow session: the incoming flow is destined to the public address, while the paired flow displays the translated private destination address. PAT is not being performed because the destination port remains 22 before and after translation. PAT would require port translation, but no port number changes are shown.
