Juniper JN0-636 Exam With Confidence Using Practice Dumps

The exhibit shows the output of the show security intelligence category summary command on the SRX-1 device. This command displays the status of the security intelligence categories configured on the device. In the output, we can see that there are two categories configured - Proxy_Nodes and Proxy_Node3. The Proxy_Nodes category is a custom category that is created by the SRX-1 device using the adaptive threat profiling feature. The Proxy_Node3 category is a third-party category that is downloaded from the Juniper ATP Cloud service. The Proxy_Nodes category contains the IP addresses that match the security policy named Proxy-ATP on the SRX-1 device. The Proxy_Node3 category contains the IP addresses that are associated with the Tor network.

The two statements that are true based on the exhibit are:

• The SRX-1 device creates the Proxy_Nodes feed, so it cannot use it in another security policy. This is because the adaptive threat profiling feature does not allow the device that creates the feed to use it in another security policy. The feed is intended to be shared with other devices in the same realm through the Juniper ATP Cloud service. The SRX-1 device can only use the feeds that are created by other devices or downloaded from third-party sources.
• You can only use the Proxy_Node3 feed as the destination-address match criteria of another security policy on a different SRX Series device. This is because the Proxy_Node3 feed is a third-party feed that is downloaded from the Juniper ATP Cloud service. The SRX-1 device can use this feed as a dynamic address object in its security policies. However, the feed is configured with the destination-only option, which means that it can only be used as the destination-address match criteria of a security policy. The source-address match criteria of a security policy cannot use this feed.

According to the security flow trace shown in the exhibit, which is a snippet of a packet capture on an SRX Series device, the two statements that are correct are:

• This packet arrived on interface ge-0/0/4.0. This is indicated by the line In: 10.0.1.129/22 -> 10.0.1.129/3382;1,0x0, which shows that the ingress interface of the packet is ge-0/0/4.0, as the interface name is prefixed to the source and destination IP addresses and ports of the packet1.
• An existing session is found in the table. This is indicated by the line Found: session id 0x12. sess tok 28685, which shows that the packet matches an existing session in the session table with the session ID 0x12 and the session token 286852.

The following statements are incorrect or not supported by the output:

• Destination NAT occurs. This is not supported by the output, as there is no indication of destination NAT being applied to the packet. The destination IP address of the packet is 10.0.1.129, which is the same as the destination IP address of the original packet. If destination NAT was applied, the destination IP address of the packet would be different from the destination IP address of the original packet.
• The capture is a packet from the source address 172.20.101.10 destined to 10.0.1.129. This is false, as the output shows that the source address of the packet is 10.0.1.129, not 172.20.101.10. The source IP address of the packet is prefixed to the ingress interface name ge-0/0/4.0.
