Learning knowledge is not only to increase the knowledge reserve, but also to understand how to apply it, and to carry out the theories and principles that have been learned into the specific answer environment. The Security, Specialist (JNCIS-SEC) exam dumps are designed efficiently and pointedly, so that users can check their learning effects in a timely manner after completing a section. Good practice on the success rate of JN0-336 Quiz guide is not fully indicate that you have mastered knowledge is skilled, therefore, the JN0-336 test material let the user consolidate learning content as many times as possible, although the practice seems very boring, but it can achieve the result of good consolidate knowledge.
NEW QUESTION # 56
Which two statements are correct about cluster components? (Choose two.)
Answer: B,D
Explanation:
The correct answers are A and B. In an SRX chassis cluster, the cluster ID identifies the chassis cluster itself, while the node ID identifies the individual SRX device inside that two-node cluster. Juniper states that a cluster is identified by a cluster-id value from 1 through 255, and that setting the cluster ID to 0 is equivalent to disabling clustering. Therefore, option A is correct and option C is wrong.
Option B is also correct because Juniper states that a cluster node is identified by a node ID specified as a number from 0 through 1. A normal SRX chassis cluster has two nodes: node0 and node1. The two devices must use the same nonzero cluster ID so they belong to the same cluster, but each device must use a different node ID so Junos can apply node-specific configuration, interface numbering, redundancy-group ownership, and management settings correctly. Option D is wrong because node IDs do not range from 1 through 255; that range applies to cluster IDs, not node IDs. Reference topics: HA Clustering, cluster ID, node ID, chassis cluster formation, node0/node1 identification.
NEW QUESTION # 57
You want to show tabular data for operational mode commands.
In this scenario, which logging parameter will provide this function?
Answer: D
Explanation:
The correct answer is B. count. In Junos security policy configuration, count is the policy parameter used for accounting and tabular operational visibility. Juniper's security policy configuration rules state that accounting and auditing elements can be specified with count and log, while logging itself is enabled at either session-init or session-close.
The operational result is visible through commands such as show security policies hit-count, which displays a table of policy hit counters, including fields such as index, from-zone, to-zone, policy name, policy count, and action. Juniper defines this command as displaying the number of times a security policy rule matches traffic, and the sample output is explicitly tabular. Option A, permit, is an action, not a counter or logging/accounting parameter. Option C, session-init, logs at the beginning of a session, and option D, session-close, logs at session teardown. Those two parameters generate logs, but they do not provide the tabular policy-count view being asked about. Reference topics: security policy accounting, count parameter, hit-count, operational-mode policy monitoring, session-init/session-close logging.
NEW QUESTION # 58
Which two statements are correct about the Junos IPS feature? (Choose two.)
Answer: A,C
Explanation:
Junos IPS is a feature that provides intrusion prevention and detection services on SRX Series devices.
It monitors network traffic and compares it against predefined signatures or custom rules to identify and block malicious or unwanted packets. Two statements that are correct about the Junos IPS feature are:
IPS is integrated as a security service on SRX Series devices: Junos IPS is not a separate platform or device, but a security service that runs on SRX Series firewalls. It can be enabled and configured as part of the security policy on the SRX Series device and applied to specific zones, interfaces, or traffic flows.
IPS uses protocol anomaly rules to detect unknown attacks: Junos IPS uses two types of rules to detect attacks: signature rules and protocol anomaly rules. Signature rules match traffic against known attack patterns or signatures and block them based on predefined actions. Protocol anomaly rules detect deviations from the expected behavior or structure of common protocols, such as TCP, UDP, ICMP, etc.
Protocol anomaly rules can help identify unknown or zero-day attacks that may not have a signature yet.

NEW QUESTION # 59
Exhibit
You are trying to create a security policy on your SRX Series device that permits HTTP traffic from your private 172 25.11.0/24 subnet to the Internet You create a policy named permit-http between the trust and untrust zones that permits HTTP traffic. When you issue a commit command to apply the configuration changes, the commit fails with the error shown in the exhibit.
Which two actions would correct the error? (Choose two.)
Answer: C,D
Explanation:
The error message indicates that the Junos-http application is not defined, so you need to either create a custom application or modify the security policy to use the built-in Junos-http application. Doing either of these will allow you to successfully commit the configuration.
NEW QUESTION # 60
You have configured a new site-to-site VPN tunnel. The exhibit shows the security IPsec statistics output for the specific tunnel index from one of the tunnel-end devices.
Which two statements are correct in this scenario? (Choose two.)
Answer: C,D
Explanation:
The correct answers are C and D. The exhibit shows ESP encrypted bytes = 0, ESP decrypted bytes = 0, encrypted packets = 0, and decrypted packets = 0. That means no traffic is successfully passing through the IPsec tunnel. Juniper's show security ipsec statistics command displays ESP encrypted/decrypted packet and byte counters, so zero values on these counters indicate that the tunnel is not successfully carrying protected ESP traffic.
Option C is also correct because the output shows ESP authentication failures and ESP decryption failures.
Since ESP is the IPsec protocol responsible for encrypted payload handling, failures in ESP authentication
/decryption point to an ESP/IPsec Phase 2 mismatch or incorrect configuration, such as mismatched authentication algorithm, encryption algorithm, keys, proposal parameters, or incompatible negotiated SA settings. Juniper's IPsec overview explains that Phase 2 negotiates the IPsec SA used to authenticate traffic flowing through the tunnel, so ESP-related failures belong to the IPsec/ESP configuration path rather than AH.
Option A is wrong because the AH counters and AH authentication failures are zero; the evidence is not pointing to AH. Option B is unsupported because the output does not show peer reboot behavior. Reference topics: IPsec VPN, ESP statistics, Phase 2/IPsec SA negotiation, ESP authentication failures, ESP decryption failures.
