Question 1

Exhibit:

Referring to the exhibit, a default static route on SRX-1 sends all traffic to ISP-

AYou have configured APBR to send all requests for streaming video traffic to ISP-B. However, the return traffic from the streaming video server is coming through ISP-A, and the traffic is being dropped by SRX-1. You can only make changes on SRX-1.
How do you solve this problem?

APlace both ISP-facing interfaces in the same zone.

BChange the APBR routing instance from a forwarding instance to a virtual router instance.

CEnable AppTrack to keep track of the sessions and zones for the streaming video traffic.

DConfigure BGP to control the return path of the streaming video traffic.

Answer : D

Question 2

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?

ASecure wire

BTenant system

CTransparent mode

DLogical system

Answer : D

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 3

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.)

AEnroll the SRX Series device with Juniper ATP Cloud.

BUse a third-party connector.

CDeploy Security Director with Policy Enforcer.

DConfigure AppTrack on the SRX Series device.

EDeploy Juniper Secure Analytics.

Answer : A, B, C

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 4

Referring to the exhibit,

which statement about TLS 1.2 traffic is correct?

ATLS 1.2 traffic will be sent to routing instance R1 but not forwarded to the next hop.

BTLS 1.2 traffic will be sent to routing instance R1 and forwarded to next hop 10.1.0.1.

CTLS 1.2 traffic will be sent to routing instance R2 but not forwarded to the next hop.

DTLS 1.2 traffic will be sent to routing instance R2 and forwarded to next hop 10.2.0.1.

Answer : A

Question 5

You are asked to configure tenant systems.

Which two statements are true in this scenario? (Choose two.)

AA tenant system can have only one administrator.

BAfter successful configuration, the changes are merged into the primary database for each tenant system.

CTenant systems have their own configuration database.

DYou can commit multiple tenant systems at a time.

Answer : C, D

Each tenant system maintains its own configuration database, isolating configurations from others, enhancing security and operational efficiency. Junos OS supports multiple concurrent commit operations across tenant systems. Further details are covered in the Juniper Tenant System Guide.

When configuring tenant systems on an SRX device, the following principles apply:

Tenant Systems Have Their Own Configuration Database (Answer C): Each tenant system has its own isolated configuration database, ensuring that changes made in one tenant system do not affect others. This allows for multi-tenant environments where different tenants can have independent configurations.

Commit Multiple Tenant Systems Simultaneously (Answer D): The system allows for multiple tenant systems to be committed at the same time, simplifying management when working with multiple tenants. This is particularly useful in large environments where multiple logical systems or tenants need updates simultaneously.

Question 6

You have configured the backup signal route IP for your multinode HA deployment, and the ICL link fails.

Which two statements are correct in this scenario? (Choose two.)

AThe current active node retains the active role.

BThe active node removes the active signal route.

CThe backup node changes the routing preference to the other node at its medium priority.

DThe active node keeps the active signal route.

Answer : A, C

Question 7

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?

AChassis cluster

BSecure wire

CMultinode HA

DVirtual chassis
