At ValidExamDumps, we consistently monitor updates to the Juniper JN0-636 exam questions by Juniper. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Juniper Security, Professional exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Juniper in their Juniper JN0-636 exam. These outdated questions lead to customers failing their Juniper Security, Professional exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Juniper JN0-636 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Exhibit:
Referring to the exhibit, which two statements are correct?
Referring to the exhibit, the following statements are correct:
The other statements are incorrect because:
A) All of the entries are not a threat level 8, but a threat level 10. The threat level is a numeric value that indicates the severity of the threat associated with a dynamic address entry. The higher the threat level, the more dangerous the threat. The SRX Series device can use the threat level to prioritize the actions for the dynamic address entries. The exhibit shows that all of the entries have the cc CN, which stands for country code China. According to the Juniper documentation, the country code China has a threat level of 10, which is the highest.
D) All of the entries are not a threat level 10, but they are. See the explanation for option A.

You are required to secure a network against malware. You must ensure that in the event that a compromised host is identified within the network, the host is isolated from the rest of the network. In this scenario, after a threat has been identified, the two components that are responsible for enforcing MAC-level infected host are:
The other options are incorrect because:
B) Juniper ATP Appliance. Juniper ATP Appliance is a hardware solution that provides advanced threat prevention by detecting and blocking malware, ransomware, and other cyberattacks. Juniper ATP Appliance can analyze the network traffic and identify the compromised hosts based on their behavior and communication patterns. Juniper ATP Appliance can also send threat intelligence feeds to Policy Enforcer and SRX Series devices to enable automated threat remediation across the network. However, Juniper ATP Appliance cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices.

Exhibit:
You are troubleshooting a firewall filter shown in the exhibit that is intended to log all traffic and block
only inbound telnet traffic on interface ge-0/0/3.
How should you modify the configuration to fulfill the requirements?
To modify the configuration to fulfill the requirements, you need to modify the log-all term to add the next term action. The other options are incorrect because:
Enter the configuration mode: user@host> configure
Navigate to the firewall filter hierarchy: user@host# edit firewall family inet filter block-telnet
Add the next term action to the log-all term: user@host# set term log-all then next term
Commit the changes: user@host# commit
Exhibit
You are implementing filter-based forwarding to send traffic from the 172.25.0.0/24 network through ISP-1 while sending all other traffic through your connection to ISP-2. Your ge-0/0/1 interface connects to two networks, including the 172.25.0.0/24 network. You have implemented the configuration shown in the exhibit. The traffic from the 172.25.0.0/24 network is being forwarded as expected to 172.20.0.2, however traffic from the other network (172.25.1.0/24) is not being forwarded to the upstream 172.21.0.2 neighbor.
In this scenario, which action will solve this problem?
The exhibit shows the configuration of filter-based forwarding on an SRX Series device. Filter-based forwarding is a feature that allows the device to use firewall filters to direct traffic to different routing instances based on the match criteria. In this scenario, the device has two routing instances - ISP-1 and ISP-2 - and two firewall filters - FBF and FBF-ISP-1. The FBF filter is applied to the ge-0/0/1 interface as an input filter. The FBF filter has one term that matches the traffic from the 172.25.0.0/24 network and directs it to the ISP-1 routing instance. The ISP-1 routing instance has a static route to the next hop 172.20.0.2. The FBF-ISP-1 filter is applied to the ge-0/0/0 interface as an output filter. The FBF-ISP-1 filter has one term that matches the traffic to the 172.20.0.2 next hop and sets the forwarding class to expedited-forwarding.
The problem in this scenario is that the traffic from the other network (172.25.1.0/24) is not being forwarded to the upstream 172.21.0.2 neighbor. This is because the FBF filter does not have a term that accepts the traffic from the 172.25.1.0/24 network. The FBF filter only has one term that matches the traffic from the 172.25.0.0/24 network and directs it to the ISP-1 routing instance. The traffic from the 172.25.1.0/24 network does not match this term and is therefore discarded by the implicit deny action at the end of the filter. The traffic from the 172.25.1.0/24 network should be forwarded to the ISP-2 routing instance, which has a static default route to the next hop 172.21.0.2.
To solve this problem, you must add another term to the FBF filter to accept the traffic from the 172.25.1.0/24 network. This term should have the action accept, which means that the traffic will be forwarded according to the routing table of the master routing instance. The master routing instance has a static default route to the ISP-2 routing instance, which in turn has a static default route to the next hop 172.21.0.2. By adding this term, the traffic from the 172.25.1.0/24 network will be forwarded to the upstream 172.21.0.2 neighbor as expected.
The configuration of the new term in the FBF filter could look something like this:
[edit firewall family inet filter FBF] term 2 { from { source-address { 172.25.1.0/24; } } then { accept; } }
Exhibit
You have configured the SRX Series device to switch packets for multiple directly connected hosts that are within the same broadcast domain However, the traffic between two hosts in the same broadcast domain are not matching any security policies
Referring to the exhibit, what should you do to solve this problem?
To change the global mode to transparent bridge mode, the user should use the following command:
set protocols l2-learning global-mode transparent-bridge
