Rosalie

I passed. I would like to tell all students that they should definitely give Cramkey Dumps a try.

Maja Aug 17, 2026

That sounds great. I'll definitely check them out. Thanks for the suggestion!

River

Hey, I used Cramkey Dumps to prepare for my recent exam and I passed it.

Lewis Aug 1, 2026

Yeah, I used these dumps too. And I have to say, I was really impressed with the results.

Lennie

I passed my exam and achieved wonderful score, I highly recommend it.

Emelia Aug 13, 2026

I think I'll give Cramkey a try next time I take a certification exam. Thanks for the recommendation!

Madeleine

Passed my exam with my dream score…. Guys do give these dumps a try. They are authentic.

Ziggy Aug 27, 2026

That's really impressive. I think I might give Cramkey Dumps a try for my next certification exam.

Hassan

Highly Recommended Dumps… today I passed my exam! Same questions appear. I bought Full Access.

Kasper Aug 4, 2026

Hey wonderful….so same questions , sounds good. Planning to write this week, I will go for full access today.

Question 13

Exhibit:

Questions 13

You have deployed an SRX Series device as shown in the exhibit. The devices in the Local zone have recently been added, but their SRX interfaces have not been configured. You must configure the SRX to meet the following requirements:

Devices in the 10.1.1.0/24 network can communicate with other devices in the same network but not with other networks or the SRX.

You must be able to apply security policies to traffic flows between devices in the Local zone.

Which three configuration elements will be required as part of your configuration? (Choose three.)

Options:

set security zones security-zone Local interfaces ge-0/0/1.0

set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan-members 10

set protocols l2-learning global-mode switching

set protocols l2-learning global-mode transparent-bridge

set security zones security-zone Local interfaces irb.10

Discussion

Answer:

A, B, D

Explanation:

In this scenario, we need to configure the SRX Series device so that devices in the Local zone (VLAN 10, 10.1.1.0/24 network) can communicate with each other but not with other networks or the SRX itself. Additionally, you must be able to apply security policies to traffic flows between the devices in the Local zone.

Explanation of Answer A (Assigning Interface to Security Zone):

You need to assign the interface ge-0/0/1.0 to the Local security zone. This is crucial because the SRX only applies security policies to interfaces assigned to security zones. Without this, traffic between devices in the Local zone won't be processed by security policies.

Configuration:

set security zones security-zone Local interfaces ge-0/0/1.0

Explanation of Answer B (Configuring Ethernet-Switching for VLAN 10):

Since we are using Layer 2 switching between devices in VLAN 10, we need to configure the interface to operate in Ethernet switching mode and assign it to VLAN 10.

Configuration:

set interfaces ge-0/0/1 unit 0 family ethernet-switching vlan-members 10

Explanation of Answer D (Transparent Bridging Mode for Layer 2):

The global mode for Layer 2 switching on the SRX device must be set to transparent-bridge. This ensures that the SRX operates in Layer 2 mode and can switch traffic between devices without routing.

Configuration:

set protocols l2-learning global-mode transparent-bridge

Summary:

Interface Assignment: Interface ge-0/0/1.0 is assigned to the Local zone to allow policy enforcement.

Ethernet-Switching: The interface is configured for Layer 2 Ethernet switching in VLAN 10.

Transparent Bridging: The SRX is configured in Layer 2 transparent-bridge mode for switching between devices.

Juniper Security Reference:

Layer 2 Bridging and Switching Overview: This mode allows the SRX to act as a Layer 2 switch for forwarding traffic between VLAN members without routing. Reference: Juniper Transparent Bridging Documentation.
