NEW QUESTION # 42
Exhibit

The show network-access aaa radius-servers command has been issued to solve authentication issues.
Referring to the exhibit, to which two authentication servers will the SRX Series device continue to send requests? (Choose TWO)

• A. 192.168.30.191
• B. 192.168.30.190
• C. 192.168.30.188
• D. 200l:DB8:0:f101;:2

Answer: A,B

Explanation:
The SRX Series device will continue to send requests to authentication servers 192.168.30.190 and 192.168.30.191. This is because the exhibit shows the output of the show network-access aaa radius-servers command. This command displays the status of the RADIUS servers configured on the device. In the output, we can see that there are three RADIUS servers configured - 192.168.30.190, 192.168.30.191, and 2001:DB8:0:f101::2. However, the status of the third server is shown as "DOWN". This means that the device is not able to communicate with this server. Therefore, the device will continue to send requests to the other two servers - 192.168.30.190 and 192.168.30.191.

NEW QUESTION # 44
you must find an infected host and where the a􀆩ack came from using the Juniper ATP Cloud. Which two monitor workspaces will return the requested information? (Choose Two)

• A. File Scanning
• B. Threat Sources
• C. Encrypted Traffic
• D. Hosts

Answer: B,D

Explanation:
To find an infected host and where the attack came from using the Juniper ATP Cloud, you need to use the Hosts and Threat Sources monitor workspaces. The other options are incorrect because:
B) The File Scanning monitor workspace shows the files that have been scanned by the Juniper ATP Cloud and their verdicts (clean, malicious, or unknown). It does not show the infected hosts or the attack sources1.
D) The Encrypted Traffic monitor workspace shows the encrypted traffic that has been decrypted by the Juniper ATP Cloud and the certificates that have been used. It does not show the infected hosts or the attack sources2.
Therefore, the correct answer is A and C. You need to use the Hosts and Threat Sources monitor workspaces to find an infected host and where the attack came from using the Juniper ATP Cloud. To do so, you need to perform the following steps:
For Hosts, you need to access the Hosts monitor workspace in the Juniper ATP Cloud WebUI by selecting Monitor > Hosts. You can see the list of hosts that have been detected by the Juniper ATP Cloud and their risk scores, infection levels, and threat categories. You can filter the hosts by various criteria, such as IP address, hostname, domain, or threat category. You can also drill down into each host to see the details of the files, applications, and incidents associated with the host. You can identify the infected host by looking for the host with the highest risk score, infection level, or threat category3.
For Threat Sources, you need to access the Threat Sources monitor workspace in the Juniper ATP Cloud WebUI by selecting Monitor > Threat Sources. You can see the list of threat sources that have been detected by the Juniper ATP Cloud and their risk scores, threat categories, and geolocations. You can filter the threat sources by various criteria, such as IP address, domain, or threat category. You can also drill down into each threat source to see the details of the files, applications, and incidents associated with the threat source. You can identify the attack source by looking for the threat source with the highest risk score, threat category, or geolocation that matches the infected host.

NEW QUESTION # 48
SRX Series device enrollment with Policy Enforcer fails To debug further, the user issues the following command show configuration services security-intelligence url
https : //cloudfeeds . argon . juniperaecurity . net/api/manifeat. xml
and receives the following output:
What is the problem in this scenario?

• A. Junos Space does not have matching schema based on the
• B. The SRX Series device does not have a valid license.
• C. The device is already enrolled with Policy Enforcer.
• D. The device is directly enrolled with Juniper ATP Cloud.

Answer: B

Explanation:
According to the output of the command show configuration services security-intelligence url, the SRX Series device is directly enrolled with Juniper ATP Cloud. This is indicated by the URL https://cloudfeeds.argon.junipersecurity.net/api/manifest.xml, which is the default URL for Juniper ATP Cloud1. This means that the device is not enrolled with Policy Enforcer, which would use a different URL that includes the IP address of the Policy Enforcer server2. Therefore, the problem in this scenario is that the device is directly enrolled with Juniper ATP Cloud, which prevents it from being enrolled with Policy Enforcer.
To enroll the device with Policy Enforcer, the user needs to disenroll the device from Juniper ATP Cloud first. This can be done by using the following command:
delete services security-intelligence url
This command will remove the Juniper ATP Cloud URL from the device configuration and stop the device from receiving threat feeds from Juniper ATP Cloud1. After that, the user can enroll the device with Policy Enforcer by using the Security Director GUI or the SLAX script2.

NEW QUESTION # 50
You are deploying a virtualization solution with the security devices in your network Each SRX Series device must support at least 100 virtualized instances and each virtualized instance must have its own discrete administrative domain.
In this scenario, which solution would you choose?

• A. virtual router instances
• B. tenant systems
• C. logical systems
• D. VRF instances

Answer: C

Explanation:
A logical system is a virtualization feature in SRX Series devices that allows you to create multiple, isolated virtual routers within a single physical device. Each logical system has its own routing table, firewall policies, and interfaces, and it can be managed and configured independently of the other logical systems. Logical systems are an effective way to isolate different administrative domains and to support a large number of virtualized instances.
According to the Juniper documentation, the solution that would best meet the requirements of deploying a virtualization solution with the security devices in the network is logical systems. Logical systems are a feature that allows the SRX Series device to be partitioned into multiple logical devices, each with its own discrete administrative domain, routing table, firewall policies, VPNs, and interfaces1. Each logical system can support up to 100 virtualized instances, depending on the SRX Series model and the available resources2.
The following solutions are not suitable or incorrect for this scenario:
VRF instances: VRF instances are a type of routing instance that allows the SRX Series device to maintain multiple routing tables for different VPNs or customers. However, VRF instances do not provide separate administrative domains, firewall policies, or interfaces for each instance3.
Virtual router instances: Virtual router instances are a type of routing instance that allows the SRX Series device to create multiple logical routers, each with its own routing table and interfaces. However, virtual router instances do not provide separate administrative domains or firewall policies for each instance.
Tenant systems: Tenant systems are a feature that allows the SRX Series device to create multiple logical devices, each with its own discrete administrative domain, routing table, firewall policies, VPNs, and interfaces. However, tenant systems are only supported on the SRX1500, SRX4100, and SRX4200 devices, and each tenant system can only support up to 10 virtualized instances.

NEW QUESTION # 51

NEW QUESTION # 52
You have noticed a high number of TCP-based attacks directed toward your primary edge device.
You are asked to configure the IDP feature on your SRX Series device to block this attack.
Which two IDP attack objects would you configure to solve this problem? (Choose two.)

• A. Signature
• B. host
• C. Network
• D. Protocol anomaly

Answer: A,D

NEW QUESTION # 53
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 system-control permission flag to the operation class
• D. Add the interface-control permission flag to the operation class

Answer: C

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 # 54
Refer to the exhibit,

which two potential violations will generate alarm ? (Choose Two)

• A. the ratio of policy violation traffic compared to accepted traffic.
• B. the number of policy violation by a destination TCP port
• C. the number of policy violations by a source network identifier
• D. the number of policy violation to an application within a specified period

Answer: C,D

Explanation:
The exhibit shows a security policy configuration with a threshold of 1000 policy violations by a source network identifier and a threshold of 10 policy violations to an application within a specified period. If either of these thresholds are exceeded, an alarm will be generated. Therefore, the correct answer is A and D. The other options are incorrect because:
B) The ratio of policy violation traffic compared to accepted traffic is not a criterion for triggering an alarm. The security policy configuration does not specify any ratio or percentage of policy violation traffic that would cause an alarm.
C) The number of policy violation by a destination TCP port is also not a criterion for triggering an alarm. The security policy configuration does not specify any threshold or duration for policy violation by a destination TCP port.

NEW QUESTION # 57
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 remote IKE gateway IP address is 203.0.113.100.
• C. The local peer is assigned a dynamic IP address.
• D. The local IKE gateway IP address is 203.0.113.100.

Answer: A,B

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.
