The flow-session resource is needed in order to ensure adequate and secure communication between the two logical systems.

The flow-session resource must be defined in the security profile for the interconnect logical system because the interconnect logical system is responsible for forwarding traffic between other logical systems. The flow-session resource determines the maximum number of sessions that the interconnect logical system can create and maintain.If the flow-session resource is not allocated or is insufficient, the interconnect logical system might drop packets or fail to establish sessions1.

The NAT resources are not needed to be allocated to the interconnect logical system because the interconnect logical system does not perform any NAT operations on the traffic.The NAT resources are only relevant for the logical systems that need to translate the source or destination IP addresses or ports of the traffic1.

No resources are not needed to be allocated to the interconnect logical system is incorrect because the interconnect logical system still requires some resources to function properly, such as the flow-session resource.The interconnect logical system cannot operate without any resources allocated to it1.

The resources must be calculated based on the amount of traffic that will flow between the logical systems is partially correct, but not the best answer. The resources must be calculated based on the amount of traffic and the type of traffic that will flow between the logical systems.For example, the flow-session resource depends on the number and duration of sessions, the security-log-stream-number resource depends on the number and size of logs, and the NAT resource depends on the number and type of NAT rules1.

The two valid modes for the Juniper ATP Appliance are all-in-one and core. The all-in-one mode is a single appliance that performs both the collector and the core functions. The collector function collects traffic from the network and sends it to the core function for analysis and detection. The core function performs the threat detection, mitigation, and analytics. The all-in-one mode is suitable for small to medium-sized networks that do not require high scalability or performance. The core mode is a dedicated appliance that performs only the core function. The core mode is used in conjunction with one or more collector appliances that collect traffic from the network and send it to the core appliance for analysis and detection. The core mode is suitable for large-scale networks that require high scalability and performance.Reference: Juniper Security, Professional (JNCIP-SEC) Reference Materials source and documents: https://www.juniper.net/documentation/en_US/junos/topics/concept/security-atp-appliance-overview.html

To troubleshoot the traffic problem using the match criteria, you need to use the show security match-policies CLI command. The other options are incorrect because:

A) The show security policy-report CLI command displays the policy report, which is a summary of the policy usage statistics, such as the number of sessions, bytes, and packets that match each policy.It does not show the match criteria or the reason why the traffic is not hitting the policy1.

B) The show security application-tracking counters CLI command displays the application tracking counters, which are the statistics of the application usage, such as the number of sessions, bytes, and packets that match each application.It does not show the match criteria or the reason why the traffic is not hitting the policy2.

D) The request security policies check CLI command checks the validity and consistency of the security policies, such as the syntax, the references, and the conflicts.It does not show the match criteria or the reason why the traffic is not hitting the policy3.

Therefore, the correct answer is C. You need to use the show security match-policies CLI command to troubleshoot the traffic problem using the match criteria. The show security match-policies CLI command displays the policies that match the specified criteria, such as the source and destination addresses, the zones, the protocols, and the ports. It also shows the action and the hit count of each matching policy.You can use this command to verify if the traffic is matching the expected policy or not, and if not, what policy is blocking or rejecting the traffic4

According to the Juniper documentation, a tenant system is a logical system that supports routing, services, and security features. A tenant system can be configured to log binary security events to a remote server using the pi security profile. The pi security profile specifies the tenant name, the server address, the server port, and the protocol for logging binary security events. In the exhibit, the pi security profile is configured with the server address 10.0.0.1, the server port 514, and the protocol UDP. However, the tenant name is missing from the configuration. To complete the configuration, the tenant name must be configured as local for the pi security profile. This is because the local tenant name is used to identify the tenant system that is sending the binary security events to the remote server. Therefore, the correct statement to complete the configuration is D.Configure the tenant as local for the pi security profile.Reference: [Tenant Systems Overview]1, [Configuring Binary Security Event Logging for Tenant Systems]2

The exhibit shows the output of the 'show interfaces ge-0/0/5.0 extensive' command on an SRX Series device. The output includes a section called 'Security' that lists the protocols that are allowed on the ge-0/0/5.0 interface. The protocols that are allowed on the ge-0/0/5.0 interface are:

OSPF

DHCP

NTP

It's important to notice that the output don't have IBGP, IPsec, so these protocols are not allowed on the ge-0/0/5.0 interface.
