I passed the Juniper Security, Professional exam, and the Pass4Success practice questions were invaluable. One question that caught me off guard was related to Advanced Policy-Based Routing (APBR), asking about the use of route maps in traffic steering. I wasn't entirely sure of the syntax, but I managed to pass.

Successfully passing the Juniper Security, Professional exam was a great relief, and the Pass4Success practice questions were a big part of my study routine. A memorable question was about Multinode High Availability (HA), specifically the role of Virtual Chassis in ensuring redundancy. I hesitated on the specifics, but my preparation saw me through.

I am thrilled to have passed the Juniper Security, Professional exam, and I owe a lot to the Pass4Success practice questions. During the exam, I faced a question on Automated Threat Mitigation, which asked about the integration of threat intelligence feeds into security policies. I wasn't sure about the exact configuration steps, but my overall knowledge helped me succeed.

Passing the Juniper Security, Professional exam was a significant achievement for me, thanks in part to the Pass4Success practice questions. One challenging question was about Layer 2 Security, specifically focusing on the role of MACsec in securing Ethernet frames. I had to think hard about the encryption process, but I managed to pass regardless.

I recently cleared the Juniper Security, Professional exam, and the practice questions from Pass4Success were a great help. A tricky question I encountered involved Advanced Network Address Translation (NAT), asking about the differences between source NAT and destination NAT in a dual-homed environment. I wasn't entirely confident in my answer, but it seems my preparation paid off.

Having just passed the Juniper Security, Professional exam, I can say that the Pass4Success practice questions were instrumental in my preparation. One question that stood out was about configuring Advanced IPsec VPNs, specifically regarding the use of Perfect Forward Secrecy (PFS) in phase 2 negotiations. I was a bit unsure about the exact benefits of PFS, but thankfully, my overall understanding was enough to get me through.

Free Juniper JN0-637 Exam Actual Questions

Note: Premium Questions for JN0-637 were last updated On Jan. 18, 2025 (see below)

Question #1

Which encapsulation type must be configured on the lt-0/0/0 logical units for an interconnect

logical systems VPLS switch?

Reveal Solution Hide Solution
Correct Answer: C

Question #2

Referring to the exhibit, which two statements are true ?

Reveal Solution Hide Solution
Correct Answer: B, D

Question #3

You want to enable transparent mode on your SRX series device.

In this scenario, which three actions should you perform? (Choose three.)

Reveal Solution Hide Solution
Correct Answer: A, C, E

Question #4

You have a multinode HA default mode deployment and the ICL is down.

In this scenario, what are two ways that the SRX Series devices verify the activeness of their peers? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: A, D

Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference

Understanding the Scenario:

Multinode HA Default Mode Deployment:

In a chassis cluster, two SRX devices operate together to provide high availability.

ICL (Inter-Cluster Link) is Down:

The control and fabric links between the nodes are not operational.

Objective:

Determine how the SRX devices verify each other's activeness without the ICL.

Option A: Custom IP addresses may be configured for the activeness probe.

When the control link is down, SRX devices use an ICMP ping-based activeness probe to check the peer's status.

Custom IP addresses can be configured as probe targets to verify the peer's activeness.


'You can configure the SRX Series device to send activeness probes to a configured IP address to verify the peer's state when the control link is down.'

Source: Juniper Networks Documentation - Control Link Failure Detection

Option D: Each peer sends a probe with the virtual IP address as the source IP address and the upstream router as the destination IP address.

The SRX devices send ICMP probes to an upstream device using the redundancy group's virtual IP address as the source.

This helps determine if the peer node is still active by verifying network reachability.

'When the control link fails, each node sends ICMP pings to the configured probe addresses using the redundancy group's virtual IP address as the source.'

Source: Juniper Networks Documentation - Chassis Cluster Control Link Failure

Why Options B and C are Incorrect:

Option B: Fabric link heartbeats cannot be used because the ICL (which includes the fabric link) is down.

Option C: Probes are sent to upstream devices, not using the virtual IP address as the destination.

Conclusion:

The correct options are A and D because they accurately describe how SRX devices verify activeness without the ICL.

Question #5

Click the Exhibit button.

Referring to the exhibit. SRX-1 and SRX-3 have to be connected using EBGP. The BGP configuration on SRX-1 and SRX-3 is verified and correct.

Which configuration on SRX-2 would establish an EBGP connection successfully between SRX-1 and SRX-3?

Reveal Solution Hide Solution
Correct Answer: D

Comprehensive Detailed Step-by-Step Explanation with All Juniper Security Reference

Understanding the Scenario:

SRX-1 and SRX-3:

Need to establish an EBGP session through SRX-2.

Issue:

BGP session is not coming up despite correct configurations on SRX-1 and SRX-3.

Option D: The security policy to allow SRX-1 and SRX-3 to communicate on TCP port 179 should be configured.

BGP uses TCP port 179 for establishing sessions.

SRX-2 must have a security policy allowing traffic between SRX-1 and SRX-3 on TCP port 179.


'Security policies must permit BGP traffic (TCP port 179) to allow BGP sessions through the SRX device.'

Source: Juniper TechLibrary - Configuring Security Policies for Transit Traffic

Why Other Options Are Incorrect:

Option A: Host-inbound-traffic affects traffic destined to SRX-2, not transit traffic.

Option B and C: TCP ports 79 and 169 are unrelated to BGP.

Conclusion:

The correct option is D, configuring a security policy to allow TCP port 179.
