JN0-637 Referring Practice Questions
The free JN0-637: Security - Professional (JNCIP-SEC) questions that deal with referring, with answers and explanations. The full bank and the timed practice test cover every topic the exam asks about.
Question #2
Exhibit: Referring to the exhibit, which two statements are correct? (Choose two.)
Select 2 answers.
Correct answer: C, D
Explanation
The interfaces are active and respond to ARP for virtual IP as long as the node is the primary or active node in the SRG group. This ensures high availability and proper traffic forwarding. For information, refer to Juniper SRX HA Documentation. The exhibit shows information about a chassis cluster and its services redundancy group (SRG1). Let's analyze the relevant details: • Explanation of Answer B (Backup Node for SRG1): • Explanation of Answer A (Interfaces Not Active): Juniper Security Reference: • Chassis Cluster Redundancy Overview: In a chassis cluster, the backup node does not respond to ARP requests for the virtual IP. Only the active node handles such requests to ensure seamless traffic forwarding. Reference: Juniper Chassis Cluster Documentation. ==========
Question #7
Exhibit: The Ipsec VPN does not establish when the peer initiates, but it does establish when the SRX series device initiates. Referring to the exhibit, what will solve this problem?
Correct answer: C
Question #8
Exhibit: You have deployed a pair of SRX series devices in a multimode HA environment. You need to enable IPsec encryption on the interchassis link. Referring to the exhibit, which three steps are required to enable ICL encryption? (Choose three.)
Select 3 answers.
Correct answer: A, C, D
Explanation
• A. Install the Junos IKE package on both nodes. While I previously stated that IKE is usually included in the base Junos OS image, it's essential to ensure that the necessary IKE package is indeed installed and enabled on both SRX nodes to support ICL encryption. • C. Configure a VPN profile for the HA traffic and apply it to both nodes. This dedicated VPN profile defines the security parameters (encryption algorithms, authentication, etc.) specifically for the ICL traffic. • D. Enable HA link encryption in the IPsec profile on both nodes. Within the IPsec profile, you must explicitly enable ICL encryption to ensure that all traffic traversing the interchassis link is protected. Why E is incorrect: • E. Enable HA link encryption in the IKE profile on both nodes. While securing IKE negotiations is important, it's typically handled within the IPsec profile itself when configuring ICL encryption on SRX devices.
