QUESTION: 13

You are asked to create multiple virtual routers using a single SRX Series device. You must ensure that each virtual router maintains a unique copy of the routing protocol daemon (RPD) process.
Which solution will accomplish this task?

Secure wire
Tenant system
Transparent mode
Logical system

Answer(s): D

Explanation:

Logical systems on SRX Series devices allow the creation of separate virtual routers, each with its unique RPD process. This segmentation ensures that routing and security policies are isolated across different logical systems, effectively acting like independent routers within a single SRX device. For further information, see Juniper Logical Systems Documentation.

To create multiple virtual routers on a single SRX Series device, each with its own unique copy of the routing protocol daemon (RPD) process, you need to use logical systems. Logical systems allow for the segmentation of an SRX device into multiple virtual routers, each with independent configurations, including routing instances, policies, and protocol daemons.

Explanation of Answer D (Logical System):
A logical system on an SRX device enables you to create multiple virtual instances of the SRX, each operating independently with its own control plane and routing processes. Each logical system gets a separate copy of the RPD process, ensuring complete isolation between virtual routers. This is the correct solution when you need separate routing instances with their own RPD processes on the same physical device.
Configuration Example:
bash set logical-systems <logical-system-name> interfaces ge-0/0/0 unit 0 set logical-systems <logical-system-name> routing-options static route 0.0.0.0/0 next-hop 192.168.1.1

QUESTION: 14

Click the Exhibit button.

Referring to the exhibit, which three actions do you need to take to isolate the hosts at the switch port level if they become infected with malware? (Choose three.)

Enroll the SRX Series device with Juniper ATP Cloud.
Use a third-party connector.
Deploy Security Director with Policy Enforcer.
Configure AppTrack on the SRX Series device.
Deploy Juniper Secure Analytics.

Answer(s): A,B,C

Explanation:

A. Enroll the SRX Series device with Juniper ATP Cloud. This is essential for the SRX to receive threat intelligence from ATP Cloud, enabling it to identify infected hosts and take action. B. Use a third-party connector. In this specific scenario, a third-party connector is required to integrate the SRX with the third-party switch.
While Juniper has native integration for its EX switches, a connector is necessary to communicate with and manage the third-party switch. C. Deploy Security Director with Policy Enforcer. Security Director orchestrates the automated response, and Policy Enforcer translates the policies into device-specific commands for the SRX and the third-party switch (via the connector).

QUESTION: 15

You want to deploy two vSRX instances in different public cloud providers to provide redundant security services for your network. Layer 2 connectivity between the two vSRX instances is not possible.
What would you configure on the vSRX instances to accomplish this task?

Chassis cluster
Secure wire
Multinode HA
Virtual chassis

Answer(s): C

QUESTION: 16

You are asked to connect two hosts that are directly connected to an SRX Series device. The traffic should flow unchanged as it passes through the SRX, and routing or switch lookups should not be performed. However, the traffic should still be subjected to security policy checks.
What will provide this functionality?

MACsec
Mixed mode
Secure wire
Transparent mode

Answer(s): C

Explanation:

Secure wire mode on SRX devices allows traffic to flow transparently through the firewall without being routed or switched, while still applying security policies. This is ideal for scenarios where traffic inspection is required without altering the traffic path or performing additional routing decisions. For further details on Secure Wire, refer to Juniper Secure Wire Documentation.

In this scenario, you want traffic to pass through the SRX unchanged (without routing or switching lookups) but still be subject to security policy checks. The best solution for this requirement is Secure

Wire.
Explanation of Answer C (Secure Wire):
Secure Wire allows traffic to flow through the SRX without any Layer 3 routing or Layer 2 switching decisions. It effectively bridges two interfaces at Layer 2 while still applying security policies. This ensures that traffic remains unchanged, while security policies (such as firewall rules) can still be enforced.
This is an ideal solution when you need the SRX to act as a "bump in the wire" for security enforcement without changing the traffic or performing complex network lookups.
