NEW QUESTION # 16
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?
- A. Delete the log-all term
- B. Modify the log-all term to add the next term action
- C. Apply a firewall filter to the loopback interface that blocks Telnet traffic
- D. Add a term before the log-all term that blocks Telnet
Answer: B
Explanation:
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:
B) Deleting the log-all term would prevent logging all traffic, which is one of the requirements. The log-all term matches all traffic from any source address and logs it to the system log file1.
C) Adding a term before the log-all term that blocks Telnet would also prevent logging all traffic, because the log-all term would never be reached. The firewall filter evaluates the terms in sequential order and applies the first matching term. If a term before the log-all term blocks Telnet, then the log-all term would not match any traffic and no logging would occur2.
D) Applying a firewall filter to the loopback interface that blocks Telnet traffic would not block inbound Telnet traffic on interface ge-0/0/3, which is another requirement. The loopback interface is a logical interface that is always up and reachable. It is used for routing and management purposes, not for filtering traffic on physical interfaces3.
Therefore, the correct answer is A. You need to modify the log-all term to add the next term action. The next term action instructs the firewall filter to continue evaluating the subsequent terms after matching the current term. This way, the log-all term would log all traffic and then proceed to the block-telnet term, which would block only inbound Telnet traffic on interface ge-0/0/34. To modify the log-all term to add the next term action, you need to perform the following steps:
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 Reference: log (Firewall Filter Action) Firewall Filter Configuration Overview loopback (Interfaces) next term (Firewall Filter Action)

NEW QUESTION # 22
you are connecting two remote sites to your corporate headquarters site. You must ensure that traffic passes corporate headquarter.
- A. In this scenario, which VPN should be used?
- B. a full mesh Layer 3 VPN with the BGP route reflector behind the corporate firewall device
- C. hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device
- D. full mesh IPsec VPNs with tunnels between all sites
- E. a Layer 3 VPN with the corporate firewall acting as the hub device
Answer: C
Explanation:
The most appropriate VPN topology when you need to ensure that all traffic from remote sites passes through the corporate headquarters would be a hub-and-spoke model. In this model, the corporate headquarters acts as the hub, and all remote sites (spokes) connect to it. This ensures that inter-site traffic goes through the headquarters, which can be important for security policy enforcement, logging, or other centralized services.
Hub-and-spoke IPsec VPN with the corporate firewall acting as the hub device - This setup will ensure that all traffic from the remote sites is routed through the corporate headquarters, allowing centralized control and inspection of the traffic.

NEW QUESTION # 32
A company wants to paron their physical SRX series firewall into multiple logical units and assign each unit (tenant) to a department within the organization. You are the primary administrator of firewall and a colleague is the administrator for one of the departments.
Which two statements are correct about your colleague? (Choose two)
- A. The colleague can access and view the resources of the tenant system.
- B. The colleague can modify the number of allocated resources for the tenant system
- C. The colleague can configure the resources allocated and routing protocols
- D. The colleague can create and assign logical interfaces to the tenant system
Answer: A,D
Explanation:
A)company wants to partition their physical SRX series firewall into multiple logical units and assign each unit (tenant) to a department within the organization. You are the primary administrator of the firewall and a colleague is the administrator for one of the departments.
The two statements that are correct about your colleague are:
B) The colleague can access and view the resources of the tenant system. A tenant system is a type of logical system that is created and managed by the primary administrator of the firewall. A tenant system has its own discrete administrative domain, logical interfaces, routing instances, security policies, and other features. The primary administrator can assign a tenant system to a department within the organization and delegate the administration of the tenant system to a colleague. The colleague can access and view the resources of the tenant system, such as the allocated CPU, memory, and bandwidth, and the configured interfaces, zones, and policies1.
C) The colleague can create and assign logical interfaces to the tenant system. A logical interface is a software interface that represents a subset of the physical interface. A logical interface can have its own address, encapsulation, and routing parameters. The primary administrator can allocate a number of logical interfaces to a tenant system and allow the colleague to create and assign logical interfaces to the tenant system. The colleague can configure the logical interfaces with the appropriate address, encapsulation, and routing parameters for the tenant system2.
The other statements are incorrect because:
A) The colleague cannot configure the resources allocated and routing protocols. The resources allocated and routing protocols are configured by the primary administrator of the firewall. The primary administrator can allocate a fixed amount of resources, such as CPU, memory, and bandwidth, to a tenant system and specify the routing protocols that are allowed for the tenant system. The colleague cannot modify the resources allocated or routing protocols for the tenant system1.
D) The colleague cannot modify the number of allocated resources for the tenant system. The number of allocated resources for the tenant system is configured by the primary administrator of the firewall. The primary administrator can allocate a fixed amount of resources, such as CPU, memory, and bandwidth, to a tenant system and monitor the resource usage of the tenant system. The colleague cannot modify the number of allocated resources for the tenant system1.

NEW QUESTION # 34
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 system permission flag to the operation class
- B. Add the interface-control permission flag to the operation class
- C. Add the system-control permission flag to the operation class
- D. Add the floppy permission flag to the operations 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: login (System) How to mount a USB drive on EX/SRX/MX/QFX Series platforms to import/export files
NEW QUESTION # 35
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.
In this scenario after a threat has been identified, which two components are responsible for enforcing MAC-level infected host?
- A. Policy Enforcer
- B. SRX Series device
- C. EX Series device
- D. Juniper ATP Appliance
Answer: A,C
Explanation:
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:
C) Policy Enforcer. Policy Enforcer is a software solution that integrates with Juniper ATP Cloud and Juniper ATP Appliance to provide automated threat remediation across the network. Policy Enforcer can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies on the SRX Series devices and the EX Series devices. Policy Enforcer can also enforce MAC-level infected host, which is a feature that allows you to quarantine a compromised host by blocking its MAC address on the switch port. Policy Enforcer can communicate with the EX Series devices and instruct them to apply the MAC-level infected host policy to the infected host1.
D) EX Series device. EX Series devices are Ethernet switches that can provide Layer 2 and Layer 3 switching capabilities and security features. EX Series devices can integrate with Policy Enforcer and Juniper ATP Cloud or Juniper ATP Appliance to provide automated threat remediation across the network. EX Series devices can support MAC-level infected host, which is a feature that allows them to quarantine a compromised host by blocking its MAC address on the switch port. EX Series devices can receive instructions from Policy Enforcer and apply the MAC-level infected host policy to the infected host2.
The other options are incorrect because:
A) SRX Series device. SRX Series devices are high-performance firewalls that can provide Layer 3 and Layer 4 security features and integrate with Juniper ATP Cloud or Juniper ATP Appliance to provide advanced threat prevention. SRX Series devices can receive threat intelligence feeds from Juniper ATP Cloud or Juniper ATP Appliance and apply them to the security policies. However, SRX Series devices cannot enforce MAC-level infected host, which is a feature that requires Layer 2 switching capabilities and is supported by EX Series devices3.
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.
