The following statements are true regarding tenant systems on SRX Series devices:

• Each tenant system runs its own instance of the routing protocol process. Each tenant system is isolated, and it has its own routing table, interfaces, and security policies.
• A maximum of 500 tenant systems can be configured on a physical SRX device. This allows for a high degree of flexibility and scalability, as each tenant system can be configured with its own set of features and security policies.

A maximum of 32 tenant systems can be configured on a physical SRX device and All tenant systems share a single routing protocol process are not correct statements

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 output of the traceoptions file called radius, the source of the problem is that the RADIUS server IP address is unreachable. This is indicated by the line FAILURE: sendto: No route to host, which shows that the SRX device cannot send the authentication request to the RADIUS server. This could be due to a network issue, such as a misconfigured route, a firewall blocking the traffic, or a physical link failure.

To troubleshoot this issue, the user should check the following:

• The RADIUS server IP address and port are correctly configured on the SRX device. The user can verify this by using the command show configuration access radius-server1.
• The SRX device can ping the RADIUS server IP address. The user can use the command ping  to test the connectivity2.
• The SRX device has a valid route to the RADIUS server IP address. The user can use the command show route  to check the routing table3.
• The SRX device and the RADIUS server are using the same shared secret key. The user can verify this by using the command show configuration access radius-server secret1.
• The SRX device and the RADIUS server are using the same authentication protocol. The user can verify this by using the command show configuration access profile 4.
• The firewall policies on the SRX device and any intermediate devices are allowing the RADIUS traffic. The user can use the command show security policies from-zone to-zone  to check the firewall policies5.
