NEW QUESTION # 42
Exhibit
You configure a traceoptions file called radius on your returns the output shown in the exhibit What is the source of the problem?
- A. The authentication order is misconfigured.
- B. The RADIUS server IP address is unreachable.
- C. The RADIUS server suffered a hardware failure.
- D. An incorrect password is being used.
Answer: D
Explanation:
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 <RADIUS-server-IP> 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 <RADIUS-server-IP> 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 <profile-name>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 <source-zone> to-zone <destination-zone> to check the firewall policies5.
NEW QUESTION # 43
Exhibit
Which two statements are correct about the output shown in the exhibit? (Choose two.)
- A. The packet matches the default security policy.
- B. The packet matches a configured security policy.
- C. The packet is processed in the first path packet flow.
- D. The packet is processed as host inbound traffic.
Answer: C,D
Explanation:
The packet is processed as host inbound traffic because the traceoptions output shows that the destination IP address 10.10.10.1 belongs to the SRX device itself, which is configured with the ge-0/0/1.0 interface. The traceoptions output also shows the flag flow_host_inbound, which indicates that the packet is destined to the device.
The packet matches the default security policy because the traceoptions output shows that the policy name is default-deny, which is the implicit system-default security policy that denies all packets. The traceoptions output also shows the flag flow_policy_deny, which indicates that the packet is denied by the policy.

NEW QUESTION # 44
While troubleshooting security policies, you added the count action. Where do you see the result of this action?
- A. In the show security flow statistics command output.
- B. In the show security policies detail command output.
- C. In the show firewall log command output.
- D. In the show security policies hit-count command output.
Answer: B
Explanation:
The result of adding the count action to a security policy can be seen in the show security policies detail command output. The count action is a feature that allows you to enable statistics collection for sessions that enter the device for a given policy, and for the number of packets and bytes that pass through the device in both directions for a given policy. The count action can help you to monitor the traffic that matches a security policy and to troubleshoot security policy issues. The show security policies detail command displays the detailed information about the security policies configured on the device, including the count statistics. The output shows the number of packets and bytes that have been processed by the policy in both directions, as well as the number of sessions that have been created by the policy. You can use this command to verify that the count action is working as expected and to see the traffic volume and session count for each policy.

NEW QUESTION # 49
Exhibit
Which two statements are correct about the output shown in the exhibit? (Choose two.)
- A. The packet is part of a new session.
- B. The packet is explicitly rejected.
- C. The packet is part of an existing session.
- D. The packet is silently discarded.
Answer: A,D
Explanation:
The packet is silently discarded because the traceoptions output shows that the packet is dropped with the flag flow_spu_drop, which indicates that the packet is dropped by the SPU without sending any response to the sender. The traceoptions output also shows the reason for the drop as "no session found, start first path. in_tunnel - 0, from_cp_flag - 0" which means that the packet does not match any existing session and is not part of a tunnel or a control plane traffic1.
The packet is part of a new session because the traceoptions output shows that the packet is the first packet of a TCP connection with the flag flow_tcp_syn, which indicates that the packet has the SYN flag set. The traceoptions output also shows that the packet is processed in the first path packet flow with the message "no session found, start first path" which means that the packet is initiating a new session1.

NEW QUESTION # 54
You are asked to download and install the IPS signature database to a device operating in chassis cluster mode. Which statement is correct in this scenario?
- A. The IPS signature package must be downloaded and installed on the primary and backup nodes.
- B. The first synchronization of the backup node and the primary node must be performed manually.
- C. The first time you synchronize the IPS signature package from the primary node to the backup node, the primary node must be rebooted.
- D. You must download and install the IPS signature package on the primary node.
Answer: D
Explanation:
The IPS signature database is one of the major components of the intrusion prevention system (IPS). It contains definitions of different objects, such as attack objects, application signature objects, and service objects, that are used in defining IDP policy rules. As a response to new vulnerabilities, Juniper Networks periodically provides a file containing attack database updates on the Juniper Networks website. You can download this file to protect your network from new threats. Note: IPS does not need a separate license to run as a service on the SRX Series Firewall; however, a license is required for IPS updates1.
When you configure a chassis cluster, the two nodes back up each other, with one node acting as the primary device and the other as the secondary device, ensuring stateful failover of processes and services in the event of system or hardware failure. If the primary device fails, the secondary device takes over processing of traffic2.
To download and install the IPS signature database to a device operating in chassis cluster mode, you must perform the following steps:
Download the IPS signature package from the Juniper Networks website to the primary node of the chassis cluster. You can use the request security idp security-package download CLI command or the Security Director user interface to download the package. Note: You must have a valid license key installed on the device to download the package3.
Install the IPS signature package on the primary node of the chassis cluster. You can use the request security idp security-package install CLI command or the Security Director user interface to install the package. Note: You must reboot the primary node after installing the package3.
Synchronize the IPS signature package from the primary node to the backup node of the chassis cluster. You can use the request security idp security-package install-backup CLI command or the Security Director user interface to synchronize the package. Note: You do not need to reboot the backup node after synchronizing the package3.
Therefore, the correct answer is A. You must download and install the IPS signature package on the primary node. The other options are incorrect because:
B) The first synchronization of the backup node and the primary node is performed automatically after you install the package on the primary node. You do not need to perform it manually3.
C) The first time you synchronize the IPS signature package from the primary node to the backup node, the primary node does not need to be rebooted. You only need to reboot the primary node after installing the package3.
D) The IPS signature package does not need to be downloaded and installed on the primary and backup nodes separately. You only need to download and install it on the primary node and then synchronize it to the backup node3.

NEW QUESTION # 59
Refer to the Exhibit:
which two statements about the configuration shown in the exhibit are correct ?
- A. The remote peer is assigned a dynamic IP address.
- B. The local peer is assigned a dynamic IP address.
- C. The local IKE gateway IP address is 203.0.113.100.
- D. The remote IKE gateway IP address is 203.0.113.100.
Answer: A,D
Explanation:
The two statements about the configuration shown in the exhibit are correct are:
A) The remote IKE gateway IP address is 203.0.113.100. The exhibit shows that the address option under the gateway statement is set to 203.0.113.100, which specifies the IP address of the primary IKE gateway. The address option is used to configure the IP address or the hostname of the remote peer that has a static IP address1.
D) The remote peer is assigned a dynamic IP address. The exhibit shows that the dynamic option under the gateway statement is configured with various attributes, such as general-ikeid, ike-user-type, and user-at-hostname. The dynamic option is used to configure the identifier for the remote gateway with a dynamic IP address. The dynamic option also enables the SRX Series device to accept multiple connections from remote peers that have the same identifier2.
The other statements are incorrect because:
B) The local peer is not assigned a dynamic IP address, but a static IP address. The exhibit shows that the local-address option under the gateway statement is set to 192.0.2.100, which specifies the IP address of the local IKE gateway. The local-address option is used to configure the IP address of the local peer that has a static IP address1.
C) The local IKE gateway IP address is not 203.0.113.100, but 192.0.2.100, as explained above.
