Each question shows the correct answer and an explanation of why it is right
You want to use Avira Antivirus.
Which two actions should you perform to satisfy this requirement? (Choose two.)
The SRX Series devices support third-party antivirus scanning engines such as Avira. To use the Avira antivirus engine, administrators must explicitly enable the engine and ensure that the required components are properly loaded.
Enable in configuration mode:
The Avira antivirus engine must be enabled under UTM configuration mode. This step ensures the SRX device uses the Avira scanning engine for antivirus inspection.
Example:
set security utm feature-profile anti-virus avira-engine enable
Reboot the SRX device:
A system reboot is required after enabling the Avira engine to load the Avira antivirus components into memory.
Without a reboot, the Avira engine will not become active.
Why not the others?
Restarting the mgd process (Option A) only reloads the management daemon and does not load antivirus engines.
Enabling in operational mode (Option B) is not supported; the configuration must be applied in configuration mode.
Therefore, the correct actions to use Avira Antivirus are: Enable the Avira engine in configuration mode (Option D) and reboot the SRX device (Option C).
You plan to use unified security policies to identify and control nested HTTP applications. In this scenario, which two actions must you perform on your SRX Series Firewall? (Choose two.)
Unified security policies use AppID to classify and control applications based on Layer 7 inspection, including applications nested within trusted services such as HTTP. Juniper documentation states that AppID identifies dynamic or real-time Layer 4 through Layer 7 applications and that dynamic applications can be added to unified security policy match criteria. To use AppID-based control, the SRX must have the required Application Identification feature license and application signature support. Dynamic application objects must then be referenced in the security policy so the firewall can match traffic by application identity rather than only by port or protocol. Unified policies do not have to be created only in the global zone, and disabling the default policy is not required.
Which two statements are correct about a Juniper Packet Forwarding Engine? (Choose two.)
The Packet Forwarding Engine is the forwarding-plane component responsible for high-speed packet handling. Juniper documentation states that the PFE performs Layer 2 and Layer 3 packet switching, route lookups, and packet forwarding. This makes option A correct because transit traffic is forwarded by the PFE rather than by the control plane. The Routing Engine manages and programs the PFE by building routing information and copying the forwarding table to the PFE, making option B correct. Option C reverses the relationship and is therefore incorrect. Option D is also incorrect because routing tables are created and maintained by the Routing Engine and routing protocol processes; the resulting forwarding information is then installed into the PFE for packet forwarding.
Which two statements are correct about security policies in SRX Series Firewalls? (Choose two.)
In the JNCIA-SEC SRX security policy context, standard security policies control transit traffic passing through the firewall. They are not the normal mechanism for permitting management or protocol traffic destined to the SRX itself; that type of self or exception traffic is controlled with host-inbound-traffic settings. Security policies can be configured between different zones, which is inter-zone policy, or within the same zone, which is intra-zone policy. Therefore, option C is correct because policies can apply to both intra-zone and inter-zone flows. Option D is correct in the standard SRX policy model because security policies are used to control traffic transiting the firewall. Options A and B are not correct for this topic scope.
Which UI enables you to manage, monitor, and maintain multiple firewalls using a single interface?
Security Director (Option B): A Junos Space application that provides a centralized interface for managing, monitoring, and maintaining multiple SRX firewalls.
Juniper Secure Analytics (Option A): Focuses on SIEM/log analysis, not centralized firewall management.
Identity Management Service (Option C): Provides user identity integration for policy enforcement, not a management UI.
Secure Connect (Option D): A VPN client solution, not a firewall management platform.
Correct UI: Security Director
You are asked to create a security policy that controls traffic allowed to pass between the Internet and private security zones. You must ensure that this policy is evaluated before all other policy types on your SRX Series device.
In this scenario, which type of security policy should you create?
Global policies (Option D): Evaluated before zone-based policies. They allow centralized control and can apply across all zones. Perfect for Internet-to-private traffic that must be enforced before other rules.
Routing policy (Option A): Controls routing decisions, not traffic forwarding/security.
Default policy (Option B): Denies all traffic by default, but cannot be customized for early evaluation.
Zone policy (Option C): Zone-based policies apply after global policies and are limited to specific zone pairs.
Correct Policy Type: Global policy
Exam domains verified against: Official Juniper JN0-232 exam guide, last checked September 2026.
Understand the foundational architecture and capabilities of SRX devices, including their role as unified threat management platforms. Learn about interfaces, hardware specifications, initial configuration, and the packet flow through security processing stages. Covers both physical SRX Series devices and the Juniper vSRX Virtual Firewall.
Sample question from this domain above: Q3
Master the core building blocks of security configuration on Junos OS. Study security zones, screen configurations for attack prevention, address objects for traffic identification, and application definitions including Application Layer Gateways that inspect and control specific application protocols.
Design and implement access control rules that protect network resources. Understand zone-based policies that control traffic between security zones, global policies that apply across the device, and unified security policies that provide a streamlined configuration model. Learn how policies determine which traffic is allowed or denied.
Configure IP address translation to manage address space and enhance security. Study source NAT to hide internal addresses, destination NAT to expose internal services to external networks, and static NAT for one-to-one address mapping. Learn when and why each translation type is used in network design.
Deploy unified threat management features to inspect and control traffic content. Implement content filtering to block unwanted material categories, web filtering to restrict web access, antivirus scanning to detect malicious files, and antispam to filter email threats. These features work together to protect against modern network threats.
Sample question from this domain above: Q1
Diagnose and resolve security issues using Junos OS tools and logs. Troubleshoot security policies to ensure traffic flows as intended, validate configured behaviors to confirm the device operates correctly, and monitor packet flow through the security processing pipeline. Learn to interpret logs and use command-line diagnostics to identify problems.
