JN0-637 Sample Exam Questions and Answers
| QUESTION: 1 |
| Which two statements about transparent mode and Ethernet switching mode on an SRX series device are correct. Option A: In Ethernet switching mode, Layer 2 interfaces must be placed in a security zone. Option B: In Ethernet switching mode, IRB interfaces must be placed in a security zone. Option C: In transparent mode, Layer 2 interfaces must be placed in a security zone. Option D: In transparent mode, IRB interfaces must be placed in a security zone. |
| Correct Answer: B,C |
| QUESTION: 2 |
| You want to configure the SRX Series device to map two peer interfaces together and ensure that there is no switching or routing lookup to forward traffic. Which feature on the SRX Series device is used to accomplish this task? Option A: Transparent mode Option B: Secure wire Option C: Mixed mode Option D: Switching mode |
| Correct Answer: B |
| Explanation/Reference: Comprehensive Detailed Step-by-Step Explanation with All Juniper Security References Understanding Secure Wire: Secure Wire Feature: Connects two interfaces directly without any Layer 2 or Layer 3 processing. No routing or switching lookup occurs. Use Case: Ideal for scenarios where traffic needs to pass through the SRX device transparently. Option B: Secure wire |
| QUESTION: 3 |
| You are deploying IPsec VPNs to securely connect several enterprise sites with ospf for dynamic routing. Some of these sites are secured by third-party devices not running Junos. Which two statements are true for this deployment? (Choose two.) Option A: OSPF over IPsec can be used for intersite dynamic routing. Option B: Sites with overlapping address spaces can be supported. Option C: OSPF over GRE over IPsec is required to enable intersite dynamic routing Option D: Sites with overlapping address spaces cannot be supported. |
| Correct Answer: B,C |
| Explanation/Reference: Understanding the Scenario: Objective: Deploy IPsec VPNs connecting multiple enterprise sites using OSPF for dynamic routing. Challenge: Some sites use third-party devices not running Junos OS. Considerations: Compatibility between Juniper and third-party devices. Support for dynamic routing protocols (OSPF) over IPsec VPNs. Handling overlapping IP address spaces. Option Analysis: Option A: OSPF over IPsec can be used for intersite dynamic routing. Explanation: OSPF Characteristics: OSPF uses multicast addresses (224.0.0.5 and 224.0.0.6) for neighbor discovery and routing updates. IPsec Limitations: Standard IPsec tunnel mode does not support multicast traffic natively. Multicast traffic cannot traverse IPsec tunnels unless encapsulated. Juniper Solution: Juniper devices can use routed VPNs (route-based VPNs) with st0 interfaces, allowing OSPF over IPsec. However, this requires support from both ends of the VPN tunnel. Third-Party Devices: May not support OSPF over IPsec without additional configurations. Conclusion: Option A is not universally true in this scenario due to third-party device limitations. |
| QUESTION: 4 |
| You have deployed automated threat mitigation using Security Director with Policy Enforcer, Juniper ATP Cloud, SRX Series devices, and EX Series switches. In this scenario, which device is responsible for blocking the infected hosts? Option A: Policy Enforcer Option B: Security Director Option C: Juniper ATP Cloud Option D: EX Series switch |
| Correct Answer: A |
| Explanation/Reference: Policy Enforcer interacts with other network elements like EX switches to enforce blocking of infected hosts based on threat intelligence from ATP Cloud and other sources. For more information, refer to Juniper Policy Enforcer Documentation. In a Juniper automated threat mitigation setup involvingSecurity Director,Policy Enforcer,Juniper ATP Cloud,SRX Series, andEX Seriesswitches, thePolicy Enforceris the component responsible for blocking infected hosts. The role of each component is as follows: Policy Enforcer (Correct: Option A):Policy Enforcer receives threat intelligence from Juniper ATP Cloud and instructs SRX devices and EX Series switches to block or quarantine infected hosts. Policy Enforcer pushes policies to these devices to enforce the mitigation actions. Security Director (Incorrect):Security Director provides centralized management and visibility but does not directlyenforce policies. Juniper ATP Cloud (Incorrect):Juniper ATP Cloud is responsible for analyzing threats and providing intelligence but does not take direct mitigation actions. EX Series Switch (Incorrect):EX Series switches can enforce the policy pushed by Policy Enforcer but are not responsible for deciding which hosts to block. Juniper References: Juniper ATP Cloud and Policy Enforcer Documentation: Details the roles of each component in the automated threat mitigation architecture. |

Option D: The GRE interface must be placed in a zone and must have OSPF configured in is host Option E: Overlapping addresses should not exist between remote networks. |
| Correct Answer: B,D,E |
| QUESTION: 6 |
| You want to bypass IDP for traffic destined to social media sites using APBR, but it is not working and IDP is dropping the session. What are two reasons for this problem? (Choose two.) Option A: The session did not properly reclassify midstream to the correct APBR rule. Option B: IDP disable is not configured on the APBR rule. Option C: The application services bypass is not configured on the APBR rule. Option D: The APBR rule does a match on the first packet. |
| Correct Answer: A,C |
| Explanation/Reference: Explanation of Answer A (Session Reclassification): APBR (Advanced Policy-Based Routing) requires the session to be classified based on the specified rule, which can change midstream as additional packets are processed. If the session was already established before the APBR rule took effect, the traffic may not be correctly reclassified to match the new APBR rule, leading to IDP (Intrusion Detection and Prevention) processing instead of being bypassed. This can occur especially when the session was already established before the rule change. Explanation of Answer C (Application Services Bypass): For APBR to work and bypass the IDP service, theapplication services bypassmust be explicitly configured. Without this configuration, the APBR rule may redirect the traffic, but the IDP service will still inspect and potentially drop the traffic. This is especially important for traffic destined for specific sites like social media platforms where bypassing IDP is desired. Example configuration for bypassing IDP services: bash Copy code set security forwarding-options advanced-policy-based-routing profile application-servicesbypass Step-by-Step Resolution: Reclassify the Session Midstream: If the traffic was already being processed before the APBR rule was applied, ensure that the session is reclassified by terminating the current session or ensuring the APBR rule is applied from the start. Command to clear the session: bash Copy code clear security flow session destination-prefix Configure Application Services Bypass: Ensure that the APBR rule includes the application services bypass configuration to properly bypass IDP or any other security services for traffic that should not be inspected. Example configuration: bash Copy code set security forwarding-options advanced-policy-based-routing profile application-servicesbypass Juniper Security Reference: Session Reclassification in APBR: APBR requires reclassification of sessions in real-time to ensure midstream packets are processed by the correct rule. This is crucial when policies change dynamically or new rules are added. Application Services Bypass in APBR: This feature ensures that security services such as IDP are bypassed for traffic that matches specific APBR rules. This is essential for applications where performance is a priority and security inspection is not necessary. |
