NEW QUESTION # 61
Exhibit
The exhibit shows a snippet of a security flow trace.
In this scenario, which two statements are correct? (Choose two.)
- A. Destination NAT occurs.
- B. The capture is a packet from the source address 172.20.101.10 destined to 10.0.1.129.
- C. This packet arrived on interface ge-0/0/4.0.
- D. An existing session is found in the table.
Answer: C,D
Explanation:
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.
NEW QUESTION # 62

NEW QUESTION # 65
You want to enforce I DP policies on HTTP traffic.
In this scenario, which two actions must be performed on your SRX Series device? (Choose two )
- A. Match on application junos-http.
- B. Specify an action of None.
- C. Disable screen options on the Untrust zone.
- D. Choose an attacks type in the predefined-attacks-group HTTP-All.
Answer: A,D
Explanation:
To enforce IDP policies on HTTP traffic on an SRX Series device, the following actions must be performed:
Choose an attacks type in the predefined-attacks-group HTTP-All: This allows the SRX Series device to match on specific types of attacks that can occur within HTTP traffic. For example, it can match on SQL injection or cross-site scripting (XSS) attacks.
Match on application junos-http: This allows the SRX Series device to match on HTTP traffic specifically, as opposed to other types of traffic. It is necessary to properly identify the traffic that needs to be protected.
Disabling screen options on the Untrust zone and specifying an action of None are not necessary to enforce IDP policies on HTTP traffic. The first one is a feature used to prevent certain types of attacks, the second one is used to take no action in case of a match.

NEW QUESTION # 72
Exhibit
Referring to the exhibit, which two statements are true? (Choose two.)
- A. The 3uspiciou3_Endpoint3 feed is usable by any SRX Series device that is a part of the same realm as SRX-1
- B. You must manually create the suspicious_Endpoint3 feed in the Juniper ATP Cloud interface.
- C. The 3uspicious_Endpoint3 feed is only usable by the SRX-1 device.
- D. Juniper ATP Cloud automatically creates the 3uopi'cioua_Endpoints feed after you commit the security policy.
Answer: A,D
Explanation:
The suspicious_Endpoints feed is a dynamic address group that is created by Juniper ATP Cloud based on the IoT device discovery and policy enforcement feature. This feature allows the SRX Series device to send IoT traffic to Juniper ATP Cloud for analysis and classification. Juniper ATP Cloud then creates a threat feed that contains the IP addresses of the suspicious IoT devices and sends it back to the SRX Series device. The SRX Series device can then use this feed to create and enforce security policies for the IoT traffic. The suspicious_Endpoints feed is usable by any SRX Series device that is a part of the same realm as SRX-1, because the feed is shared among the devices that belong to the same Juniper ATP Cloud realm. Juniper ATP Cloud automatically creates the suspicious_Endpoints feed after you commit the security policy that references the feed, because the feed is dynamically generated based on the IoT traffic analysis. You do not need to manually create the feed in the Juniper ATP Cloud interface. Reference:

NEW QUESTION # 74
You are asked to deploy Juniper atp appliance in your network. You must ensure that incidents and alerts are sent to your SIEM.
In this scenario, which logging output format is supported?
- A. CEF
- B. WELF
- C. binay
- D. JSON
Answer: A
Explanation:
The Juniper ATP Appliance platform collects, inspects and analyzes advanced and stealthy web, file, and email-based threats that exploit and infiltrate client browsers, operating systems, emails and applications. Juniper ATP Appliance's detection of malicious attacks generates incident and event details that can be sent to connected SIEM platforms in CEF, LEEF or Syslog formats1. CEF (Common Event Format) is an open log management standard that improves the interoperability of security-related information from different vendors2. Juniper ATP Appliance supports CEF format for sending events and system audit notifications to SIEM servers. You can configure the CEF format in the Juniper ATP Appliance Central Manager WebUI Config > Notifications > SIEM Settings1. Therefore, the correct answer is C. CEF is a supported logging output format for Juniper ATP Appliance. The other options are incorrect because:
A) WELF (WebTrends Enhanced Log Format) is a proprietary log format developed by WebTrends Corporation for web analytics3. Juniper ATP Appliance does not support WELF format for SIEM integration.
B) JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans and machines to read and write4. Juniper ATP Appliance supports JSON format for HTTP API results, but not for SIEM notifications1.
D) Binary is a numeric system that uses only two digits: 0 and 1. Binary is not a logging output format for Juniper ATP Appliance or any SIEM platform.

NEW QUESTION # 76
In Juniper ATP Cloud, what are two different actions available in a threat prevention policy to deal with an infected host? (Choose two.)
- A. Quarantine the host.
- B. Drop the connection silently.
- C. Close the connection.
- D. Send a custom message
Answer: A,C
Explanation:
In Juniper ATP Cloud, a threat prevention policy allows you to define how the system should handle an infected host. Two of the available actions are:
Close the connection: This action will close the connection between the infected host and the destination to which it is trying to connect. This will prevent the host from communicating with the destination and will stop any malicious activity.
Quarantine the host: This action will isolate the infected host from the network by placing it in a quarantine VLAN. This will prevent the host from communicating with other devices on the network, which will prevent it from spreading malware or exfiltrating data.
Sending a custom message is used to notify the user and administrator of the action taken. Drop the connection silently is not an action available in Juniper ATP Cloud.
According to the Juniper documentation, the threat prevention policy in Juniper ATP Cloud is a configuration that defines the actions and notifications for different threat levels of the traffic. The threat levels are based on the verdicts returned by Juniper ATP Cloud after analyzing the files, URLs, and domains. The threat levels range from 1 to 10, where 1 is the lowest and 10 is the highest1.
The threat prevention policy allows the user to specify different actions for different threat levels. The actions can be applied to the traffic or to the infected host. The actions available for the traffic are:
Permit: Allows the traffic to pass through the SRX Series device without any interruption.
Block: Blocks the traffic and sends a reset packet to the client and the server.
Drop: Drops the traffic silently without sending any reset packet.
Redirect: Redirects the traffic to a specified URL, such as a warning page or a sinkhole server.
The actions available for the infected host are:
None: Does not take any action on the infected host.
Quarantine: Quarantines the infected host by applying a firewall filter that blocks all outbound traffic from the host, except for the traffic to Juniper ATP Cloud or the specified redirect URL.
Custom: Executes a custom script on the SRX Series device to perform a user-defined action on the infected host, such as sending an email notification or triggering an external system.
Therefore, the two different actions available in a threat prevention policy to deal with an infected host are:
Block: This action will block the traffic from or to the infected host and send a reset packet to the client and the server. This will prevent the infected host from communicating with the malicious server or spreading the malware to other hosts.
Quarantine: This action will quarantine the infected host by blocking all outbound traffic from the host, except for the traffic to Juniper ATP Cloud or the redirect URL. This will isolate the infected host from the network and allow the user to remediate the infection.
The following actions are not available or incorrect:
Send a custom message: This is not an action available in the threat prevention policy. However, the user can use the custom action to execute a script that can send a custom message to the infected host or the administrator.
Drop the connection silently: This is an action available for the traffic, not for the infected host. It will drop the traffic without sending any reset packet, which may not be effective in stopping the infection or notifying the user.
NEW QUESTION # 77
Exhibit:
Referring to the exhibit, the operator user is unable to save configuration files to a usb stick the is plugged into SRX. What should you do to solve this problem?
- A. Add the floppy permission flag to the operations class
- B. Add the system permission flag to the operation class
- C. Add the interface-control permission flag to the operation class
- D. Add the system-control permission flag to the operation class
Answer: D
Explanation:
To solve the problem of the operator user being unable to save configuration files to a USB stick that is plugged into SRX, you need to add the system-control permission flag to the operations class. The other options are incorrect because:
A) Adding the floppy permission flag to the operations class is not sufficient or necessary to save configuration files to a USB stick. The floppy permission flag allows the user to access the floppy drive, but not the USB drive. The USB drive is accessed by the system permission flag, which is already included in the operations class1.
C) Adding the interface-control permission flag to the operations class is also not sufficient or necessary to save configuration files to a USB stick. The interface-control permission flag allows the user to configure and monitor interfaces, but not to save configuration files. The configuration permission flag, which is also already included in the operations class, allows the user to save configuration files1.
D) Adding the system permission flag to the operations class is redundant and ineffective to save configuration files to a USB stick. The system permission flag allows the user to access the system directory, which includes the USB drive. However, the operations class already has the system permission flag by default1. The problem is not the lack of system permission, but the lack of system-control permission.
Therefore, the correct answer is B. You need to add the system-control permission flag to the operations class to solve the problem. The system-control permission flag allows the user to perform system-level operations, such as rebooting, halting, or snapshotting the device1. These operations are required to mount, unmount, and copy files to and from the USB drive2. To add the system-control permission flag to the operations class, you need to perform the following steps:
Enter the configuration mode: user@host> configure
Navigate to the system login class hierarchy: user@host# edit system login class operations Add the system-control permission flag: user@host# set permissions system-control Commit the changes: user@host# commit Reference:

NEW QUESTION # 80
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?
- A. You must add another term to the firewall filter to accept the traffic from the 172.25.1.0/24 network.
- B. You must create the static default route to neighbor 172.21 0.2 under the ISP-1 routing instance hierarchy.
- C. You must apply the firewall filter to the lo0 interface when using filter-based forwarding.
- D. You must specify that the 172.25.1.1/24 IP address is the primary address on the ge-0/0/1 interface.
Answer: A
Explanation:
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; } }
NEW QUESTION # 81
Your company wants to use the Juniper Seclntel feeds to block access to known command and control servers, but they do not want to use Security Director to manage the feeds.
Which two Juniper devices work in this situation? (Choose two)
- A. MX Series devices
- B. QFX Series devices
- C. EX Series devices
- D. SRX Series devices
Answer: A,D
Explanation:
Juniper MX and SRX series devices support the integration of Seclntel feeds, which provide information about known command and control servers, for the purpose of blocking access to them. These devices can be configured to use the Seclntel feeds without the need for Security Director to manage the feeds.
EX series and QFX series devices are not capable of working in this situation, as they do not support the integration of Seclntel feeds.
According to the Juniper documentation, the two Juniper devices that work in this situation are MX Series devices and SRX Series devices. These devices can use the Juniper SecIntel feeds to block access to known command and control servers without using Security Director to manage the feeds. The Juniper SecIntel feeds are curated and verified threat intelligence data that are continuously collected from Juniper ATP Cloud, Juniper Threat Labs, and other sources. The SecIntel feeds include command and control IPs, URLs, certificate hashes, and domains that are used by attackers to control malware or maintain their connection to the network1.
The MX Series devices and the SRX Series devices can subscribe to the SecIntel feeds by using the following steps:
Configure the SecIntel service on the device by specifying the SecIntel URL, the SecIntel policy, and the SecIntel license2.
Configure the SecIntel policy on the device by specifying the SecIntel feeds, the SecIntel actions, and the SecIntel logging3.
Apply the SecIntel policy to the security zones or the firewall policies on the device by using the secintel-policy option4.
Once the SecIntel service is configured and applied, the MX Series devices and the SRX Series devices will receive the SecIntel feeds from Juniper ATP Cloud and use them to block the traffic from or to the command and control servers. The SecIntel service will also send the SecIntel logs to Juniper ATP Cloud or a third-party SIEM solution for further analysis and reporting.
The following devices are not suitable or incorrect for this situation:
EX Series devices: EX Series devices are Ethernet switches that can integrate with SecIntel to block infected hosts at the switch port. However, they cannot use the SecIntel feeds to block command and control servers, as they do not support the SecIntel service or policy.
QFX Series devices: QFX Series devices are Ethernet switches that can integrate with SecIntel to block infected hosts at the switch port. However, they cannot use the SecIntel feeds to block command and control servers, as they do not support the SecIntel service or policy.
NEW QUESTION # 82
You are asked to detect domain generation algorithms
Which two steps will accomplish this goal on an SRX Series firewall? (Choose two.)
- A. Define a security-metadata-streaming policy under [edit
- B. Attach the security-metadata-streaming policy to a security
- C. Attach the advanced-anti-malware policy to a security policy.
- D. Define an advanced-anti-malware policy under [edit services].
Answer: A,B
Explanation:
According to the Juniper documentation, the steps to detect domain generation algorithms (DGA) on an SRX Series firewall are as follows:
Define a security-metadata-streaming policy under [edit services]. A security-metadata-streaming policy is a configuration that enables the SRX Series firewall to collect and stream security metadata, such as DNS queries and responses, to Juniper ATP Cloud for analysis. Juniper ATP Cloud uses machine learning models and known pre-computed DGA domain names to provide domain verdicts, which helps in-line blocking and sinkholing of DNS queries on SRX Series firewalls1. You can define a security-metadata-streaming policy by using the following command:
set services security-metadata-streaming policy <policy-name>
Attach the security-metadata-streaming policy to a security zone. A security zone is a logical grouping of interfaces that have similar security requirements. You can attach the security-metadata-streaming policy to a security zone by using the following command:
set security zones security-zone <zone-name> services security-metadata-streaming policy <policy-name> The following steps are not required or incorrect:
Define an advanced-anti-malware policy under [edit services]. An advanced-anti-malware policy is a configuration that enables the SRX Series firewall to scan files for malware using Juniper ATP Cloud. It is not related to DGA detection2.
Attach the advanced-anti-malware policy to a security policy. A security policy is a configuration that defines the rules for permitting or denying traffic between security zones. It is not related to DGA detection3.
