Generally speaking, the clients will pass the test if they have finished learning our JN0-336 test guide with no doubts. The odds to fail in the test are approximate to zero. But to guarantee that our clients wonโt suffer the loss we will refund the clients at once if they fail in the test unexpectedly. The procedures are very simple and the clients only need to send us their proofs to fail in the JN0-336 test and the screenshot or the scanning copies of the clientsโ failure scores. The clients can consult our online customer staff about how to refund, when will the money be returned backed to them and if they can get the full refund or they can send us mails to consult these issues.
NEW QUESTION # 26
You need to secure communications from a mobile command center which uses a 5G mobile ISP behind CGNAT to an SRX Series Firewall at headquarters.
Which two actions should be performed on the SRX Series Firewall in this scenario? (Choose two.)
Answer: B,D
Explanation:
The correct answers are A and D. A mobile command center using a 5G ISP behind CGNAT is operating behind dynamic address translation. For IPsec to work reliably through NAT, the SRX must support NAT Traversal, which encapsulates IKE and ESP traffic in UDP/4500 after NAT is detected. Juniper states that NAT-T is used when NAT devices exist in the datapath and that NAT keepalives are required because NAT devices age out UDP translations. Juniper's Security Director VPN workflow also specifically says to enable NAT-T when the dynamic endpoint is behind a NAT device.
DPD is also required because mobile and carrier-grade NAT connections can disappear, roam, or become stale without a clean tunnel teardown. Juniper defines Dead Peer Detection as the method used by IPsec peers to verify whether the remote peer is still present and responsive by sending encrypted IKE notification payloads and waiting for acknowledgements. Option B is not the best answer because IKEv1 aggressive mode is weaker and does not provide identity protection; Juniper also notes that aggressive mode applies only to IKEv1. Option C is invalid because IKEv2 aggressive mode does not exist. Reference topics: IPsec VPN, NAT-T, CGNAT, dynamic endpoints, DPD, IKE peer availability.
NEW QUESTION # 27
Click the Exhibit button.
You are asked to create a security policy that will automatically add infected hosts to the infected hosts feed and block further communication through the SRX Series device.
What needs to be added to this configuration to complete this task?
Answer: A
Explanation:
To create a security policy that will automatically add infected hosts to the infected hosts feed and block further communication through the SRX Series device, you need to add a security intelligence policy to the permit portion of the security policy. A security intelligence policy is a policy that allows you to block or monitor traffic from malicious sources based on threat intelligence feeds from Juniper ATP Cloud or other providers. One of the feeds that you can use is the Infected-Hosts feed, which contains IP addresses of hosts that are infected with malware and communicate with command-and-control servers.
You can create a profile and a rule for the Infected-Hosts feed and specify the threat level and the action to take for the infected hosts. Then, you can link the security intelligence policy with the firewall policy and apply it to the traffic that you want to protect.

NEW QUESTION # 28
A pair of branch SRX Series devices are booted up in cluster mode.
Referring to the exhibit, which statement is correct?
Answer: A
Explanation:
The correct answer is C. fxp0 or fxp1 on either device has an existing configuration. The exhibit shows each node reporting itself in hold state and the peer as lost under redundancy group 0. Juniper's chassis cluster troubleshooting documentation shows this same hold/lost symptom and states that when a node is in hold, it is not ready to operate in a chassis cluster. For branch SRX devices, when cluster mode is enabled, specific physical interfaces are automatically converted into fxp0 for out-of-band management and fxp1 for the HA control link. These interfaces cannot retain normal transit or standalone interface configuration. If the ports that become fxp0 or fxp1 already have configuration, the cluster can enter the hold/lost condition shown in the exhibit.
Option A is wrong because the output does not indicate a Junos version mismatch. Option B is wrong because hardware mismatch is not the symptom being shown. Option D is too specific: a factory-default configuration can cause this problem because it may include configuration on interfaces that become fxp0/fxp1, but the exhibit does not prove specifically that node1 alone is running factory-default configuration. The tested issue is the existing configuration on the interfaces reserved for chassis-cluster management/control. Reference topics: HA Clustering, chassis cluster hold/lost state, fxp0, fxp1, branch SRX cluster initialization.
NEW QUESTION # 29

Exam4Tests designed this prep material to help you pass the exam on the first try. It may sound complicated, but once you go through regular study and intensive practice, passing the final exam would be a piece of cake. The cost of Security, Specialist (JNCIS-SEC) (JN0-336) certification itself is expensive, ranging from $100 to $1000, so you can't risk wasting that amount. Exam4Tests ensures that this does not happen by providing you with reliable and updated preparation material.
