NEW QUESTION # 16
You want to enable inter-tenant communicaon with tenant system.
In this Scenario, which two solutions will accomplish this task?
- A. interconnect EVPN switch
- B. external router
- C. logical tunnel interface
- D. interconnect VPLS switch
Answer: B,C
Explanation:
To enable inter-tenant communication with tenant system, you need to use an external router or a logical tunnel interface.
The other options are incorrect because:
A) Interconnecting EVPN switch is not a valid solution for inter-tenant communication with tenant system.
EVPN (Ethernet VPN) is a technology that provides layer 2 connectivity over an IP network. It can be used to connect different logical systems on the same device, but not tenant systems. Tenant systems are isolated from each other and do not share the same layer 2 domain1.
B) Interconnecting VPLS switch is also not a valid solution for inter-tenant communication with tenant system. VPLS (Virtual Private LAN Service) is another technology that provides layer 2 connectivity over an IP network. It can also be used to connect different logical systems on the same device, but not tenant systems. Tenant systems are isolated from each other and do not share the same layer 2 domain1.
Therefore, the correct answer is C and D. You need to use an external router or a logical tunnel interface to enable inter-tenant communication with tenant system.
To do so, you need to perform the following steps:
For external router, you need to connect the external router to the interfaces of the tenant systems that you want to communicate with. You also need to configure the routing protocols and policies on the external router and the tenant systems to exchange routes and traffic. The external router acts as a gateway between the tenant systems and provides layer 3 connectivity2.
For logical tunnel interface, you need to create a logical tunnel interface on the device and assign it to a tenant system. You also need to configure the IP address and routing protocols on the logical tunnel interface and the tenant systems that you want to communicate with. The logical tunnel interface acts as a virtual link between the tenant systems and provides layer 3 connectivity3.

NEW QUESTION # 20
you must create a secure fabric in your company's network
In this Scenario, which three statements are correct? (Choose Three)
- A. Switches and connectors cannot be added to the same site
- B. A switch must be assigned to the site to enforce an infected host policy within the network
- C. MX Series device associated with tenants can belong to only one site
- D. SRX Series devices can belong to only one site
- E. SRX Series devices can belong to multiple sites
Answer: B,C,D
Explanation:
To create a secure fabric in your company's network, you need to know the following facts:
A secure fabric is a collection of sites that contain network devices (switches, routers, firewalls, and other security devices) that are used in policy enforcement groups. A site is a grouping of network devices that contribute to threat prevention. When threat prevention policies are applied to policy enforcement groups, the system automatically discovers to which sites those groups belong. This is how threat prevention is aggregated across your secure fabric1.
MX Series devices associated with tenants can belong to multiple sites. Tenants are logical partitions of the network that can have their own security policies and enforcement points. Sites that are associated with tenants do not need switches as enforcement points, because MX Series devices can perform tenant-based policy enforcement1.
SRX Series devices can belong to only one site. SRX Series devices are firewalls that can act as perimeter enforcement points for the secure fabric. They can send potentially malicious objects and files to the Juniper ATP Cloud for analysis and receive threat intelligence from the Juniper ATP Cloud to block malicious traffic. SRX Series devices cannot belong to multiple sites, because they do not support tenant-based policy enforcement1.
A switch must be assigned to the site to enforce an infected host policy within the network. An infected host policy is a policy that blocks or quarantines hosts that are identified as infected by the Juniper ATP Cloud. A switch can act as an internal enforcement point for the secure fabric by applying the infected host policy to the hosts that are connected to it. A switch must be assigned to the site where the infected hosts are located, because SRX Series devices cannot enforce infected host policies1.
Switches and connectors cannot be added to the same site. Connectors are software agents that can be installed on Windows or Linux servers to enable them to act as enforcement points for the secure fabric.
Connectors can apply infected host policies to the hosts that are connected to them. However, connectors cannot coexist with switches in the same site, because they use different methods of policy enforcement. Switches use VLANs and ACLs, while connectors use IPtables and WFP1. Therefore, the correct answer is B, D, and E. The other options are incorrect because:
A) MX Series devices associated with tenants can belong to multiple sites, not only one site1.
C) SRX Series devices can belong to only one site, not multiple sites1.

NEW QUESTION # 22
You are asked to control access to network resources based on the identity of an authenticated device.
Which three steps will accomplish this goal on the SRX Series firewalls? (Choose three)
- A. Configure the authentication source to be used to authenticate the device
- B. Configure an end-user-profile that characterizes a device or set of devices
- C. Reference the end-user-profile in the security policy.
- D. Reference the end-user-profile in the security zone
- E. Apply the end-user-profile at the interface connecting the devices
Answer: A,B,C
Explanation:
To control access to network resources based on the identity of an authenticated device on the SRX Series firewalls, you need to perform the following steps:
A) Configure an end-user-profile that characterizes a device or set of devices. An end-user-profile is a device identity profile that contains a collection of attributes that are characteristics of a specific group of devices, or of a specific device, depending on the attributes configured in the profile. The end-user- profile must contain a domain name and at least one value in each attribute. The attributes include device-identity, device-category, device-vendor, device-type, device-os, and device-os-version1. You can configure an end-user-profile by using the Junos Space Security Director or the CLI2.
C) Reference the end-user-profile in the security policy. A security policy is a rule that defines the action to be taken for the traffic that matches the specified criteria, such as source and destination addresses, zones, protocols, ports, and applications. You can reference the end-user-profile in the source-end-user- profile field of the security policy to identify the traffic source based on the device from which the traffic issued. The SRX Series device matches the IP address of the device to the end-user-profile and applies the security policy accordingly3. You can reference the end-user-profile in the security policy by using the Junos Space Security Director or the CLI4.
E) Configure the authentication source to be used to authenticate the device. An authentication source is a system that provides the device identity information to the SRX Series device. The authentication source can be Microsoft Windows Active Directory or a third-party network access control (NAC) system.
You need to configure the authentication source to be used to authenticate the device and to send the device identity information to the SRX Series device. The SRX Series device stores the device identity information in the device identity authentication table5. You can configure the authentication source by using the Junos Space Security Director or the CLI6.
The other options are incorrect because:
B) Referencing the end-user-profile in the security zone is not a valid step to control access to network resources based on the identity of an authenticated device. A security zone is a logical grouping of interfaces that have similar security requirements. You can reference the user role in the security zone to identify the user who is accessing the network resources, but not the end-user-profile7.
D) Applying the end-user-profile at the interface connecting the devices is also not a valid step to control access to network resources based on the identity of an authenticated device. You cannot apply the end- user-profile at the interface level, but only at the security policy level. The end-user-profile is not a firewall filter or a security policy, but a device identity profile that is referenced in the security policy1.

NEW QUESTION # 23
you configured a security policy permitting traffic from the trust zone to the untrust zone but your traffic not hitting the policy.
In this scenario, which cli command allows you to troubleshoot traffic problem using the match criteria?
- A. request security policies check
- B. show security application-tracking counters
- C. show security match-policies
- D. show security policy-report
Answer: C
Explanation:
To troubleshoot the traffic problem using the match criteria, you need to use the show security match- policies CLI command.
The other options are incorrect because:
A) The show security policy-report CLI command displays the policy report, which is a summary of the policy usage statistics, such as the number of sessions, bytes, and packets that match each policy. It does not show the match criteria or the reason why the traffic is not hitting the policy1.
B) The show security application-tracking counters CLI command displays the application tracking counters, which are the statistics of the application usage, such as the number of sessions, bytes, and packets that match each application. It does not show the match criteria or the reason why the traffic is not hitting the policy2.
D) The request security policies check CLI command checks the validity and consistency of the security policies, such as the syntax, the references, and the conflicts. It does not show the match criteria or the reason why the traffic is not hitting the policy3.
Therefore, the correct answer is C. You need to use the show security match-policies CLI command to troubleshoot the traffic problem using the match criteria. The show security match-policies CLI command displays the policies that match the specified criteria, such as the source and destination addresses, the zones, the protocols, and the ports. It also shows the action and the hit count of each matching policy.
You can use this command to verify if the traffic is matching the expected policy or not, and if not, what policy is blocking or rejecting the traffic4

You must setup a Ddos solution for your ISP. The solution must be agile and not block legitimate traffic.
Which two products will accomplish this task? (Choose two.)
- A. Corero Smartwall TDD
- B. MX Series device
- C. SRX Series device
- D. Contrail Insights
Answer: A,B
Explanation:
You must set up a DDoS solution for your ISP. The solution must be agile and not block legitimate traffic.
The two products that will accomplish this task are:
B) MX Series device. MX Series devices are high-performance routers that can provide DDoS protection at the network edge by integrating with Corero SmartWall Threat Defense Director (TDD) software. MX Series devices can leverage the packet processing capabilities of the MX-SPC3 Services Card to perform real-time DDoS detection and mitigation at line rate, scaling from 50 Gbps to 40 Tbps. MX Series devices can also use Juniper Networks Security Intelligence (SecIntel) to receive threat intelligence feeds from Juniper ATP Cloud or Juniper Threat Labs and apply them to the security policies.
MX Series devices can provide an agile and effective DDoS solution for your ISP without blocking legitimate traffic12.
C) Corero SmartWall TDD. Corero SmartWall TDD is a software solution that runs on MX Series devices and PTX Series devices to provide DDoS protection at the network edge. Corero SmartWall TDD uses behavioral analytics and detailed network visibility to detect and block DDoS attacks in seconds, without affecting the normal traffic. Corero SmartWall TDD can also provide advanced protection from "carpet bombing" attacks, 5G DDoS visibility, and multi-tenant portal for as-a-service offerings or views by department within an enterprise. Corero SmartWall TDD can provide an agile and effective DDoS solution for your ISP without blocking legitimate traffic34.
The other options are incorrect because:
A) Contrail Insights. Contrail Insights is a software solution that provides network analytics and visibility for cloud and data center environments. Contrail Insights can help you monitor, troubleshoot, and optimize the performance and security of your network, but it does not provide DDoS protection by itself.
Contrail Insights can integrate with other Juniper products, such as Contrail Enterprise Multicloud, Contrail Service Orchestration, and AppFormix, to provide a comprehensive network management solution, but it is not a DDoS solution for your ISP5.
D) SRX Series device. SRX Series devices are high-performance firewalls that can provide DDoS protection at the network perimeter by integrating with Juniper ATP Cloud and Juniper Threat Labs. SRX Series devices can use SecIntel to receive threat intelligence feeds from Juniper ATP Cloud or Juniper Threat Labs and apply them to the security policies. SRX Series devices can also use IDP to detect and prevent application-level attacks, such as SQL injection, cross-site scripting, and buffer overflow. SRX Series devices can provide a robust and effective DDoS solution for your network, but they are not designed to handle high-volume DDoS attacks at the network edge, as MX Series devices and Corero SmartWall TDD are.

NEW QUESTION # 29
Which two security intelligence feed types are supported?
- A. custom feeds
- B. Command and Control feed
- C. malicious URL feed
- D. infected host feed
Answer: A,D
Explanation:
The two security intelligence feed types that are supported are:
A) Infected host feed. An infected host feed is a security intelligence feed that contains the IP addresses of hosts that are infected by malware or compromised by attackers. The SRX Series device can download the infected host feed from the Juniper ATP Cloud or generate its own infected host feed based on the detection events from IDP. The SRX Series device can use the infected host feed to block or quarantine the traffic to or from the infected hosts based on the security policies1.
B) Command and Control feed. A command and control feed is a security intelligence feed that contains the IP addresses of servers that are used by malware or attackers to communicate with infected hosts.
The SRX Series device can download the command and control feed from the Juniper ATP Cloud or generate its own command and control feed based on the detection events from IDP. The SRX Series device can use the command and control feed to block or log the traffic to or from the command and control servers based on the security policies2.
The other options are incorrect because:
C) Custom feeds. Custom feeds are not a security intelligence feed type, but a feature that allows you to create your own security intelligence feeds based on your own criteria and sources. You can configure custom feeds by using the Junos Space Security Director or the CLI. Custom feeds are not supported by the Juniper ATP Cloud or the IDP3.
D) Malicious URL feed. Malicious URL feed is not a security intelligence feed type, but a feature that allows you to block or log the traffic to or from malicious URLs based on the security policies. The SRX Series device can download the malicious URL feed from the Juniper ATP Cloud or the Juniper Threat Labs. Malicious URL feed is not supported by the IDP4.

NEW QUESTION # 30
Exhibit:
Referring to the exhibit, which two statements are correct?
- A. All of the entries are a threat level 10.
- B. All of the entries are Dshield entries
- C. All of the entries are command and control entries.
- D. All of the entries are a threat level 8
Answer: B,C
Explanation:
Referring to the exhibit, the following statements are correct:
B) All of the entries are command and control entries. Command and control entries are dynamic addresses that represent the IP addresses of servers that are used by malware to communicate with infected hosts. The SRX Series device can block or log the traffic to or from these IP addresses based on the security policies. The exhibit shows that all of the entries have the category DC/1, which stands for command and control1.
C) All of the entries are Dshield entries. Dshield is a feed source that provides a list of IP addresses that are associated with malicious activities, such as scanning, spamming, or attacking. The SRX Series device can download the Dshield feed and use it to populate the dynamic address entries. The exhibit shows that all of the entries have the feed dshield, which indicates that they are from the Dshield feed source2.
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 want traffic to avoid the flow daemon for administrative task.
In this scenario which two stateless service are available with selective stateless packet based service. (Choose Two)
- A. IPv4 routing
- B. IPsec
- C. Layer 2 switching
- D. IPv6 routing
Answer: A,D
Explanation:
You want traffic to avoid the flow daemon for administrative tasks. In this scenario, the two stateless services that are available with selective stateless packet-based services are:
A) Layer 2 switching. Layer 2 switching is a stateless service that forwards packets based on the MAC addresses of the source and destination hosts. Layer 2 switching does not require any routing or flow processing, and can be performed by the Packet Forwarding Engine (PFE) of the SRX Series device.
You can use selective stateless packet-based services to enable Layer 2 switching for traffic that matches a stateless firewall filter. The firewall filter must have the packet-mode action modifier to bypass the flow daemon1.
B) IPv4 routing. IPv4 routing is a stateless service that forwards packets based on the IP addresses of the source and destination hosts. IPv4 routing does not require any flow processing, and can be performed by the PFE of the SRX Series device. You can use selective stateless packet-based services to enable IPv4 routing for traffic that matches a stateless firewall filter. The firewall filter must have the packet-mode action modifier to bypass the flow daemon1.
The other options are incorrect because:
C) IPsec. IPsec is a stateful service that provides security and encryption for IP packets. IPsec requires flow processing, and cannot be performed by the PFE of the SRX Series device. You cannot use selective stateless packet-based services to enable IPsec for traffic that matches a stateless firewall filter. The firewall filter cannot have the packet-mode action modifier to bypass the flow daemon2.
D) IPv6 routing. IPv6 routing is a stateful service that forwards packets based on the IP addresses of the source and destination hosts. IPv6 routing requires flow processing, and cannot be performed by the PFE of the SRX Series device. You cannot use selective stateless packet-based services to enable IPv6 routing for traffic that matches a stateless firewall filter. The firewall filter cannot have the packet-mode action modifier to bypass the flow daemon3.
