NEW QUESTION # 61
Exhibit

Referring to the exhibit, an internal host is sending traffic to an Internet host using the 203.0.113.1 reflexive address with source port 54311.
Which statement is correct in this situation?

• A. Any host on the Internet can initiate traffic to reach the internal host using the 203.0.113.1 address, source port 54311, and a random destination port.
• B. Any host on the Internet can initiate traffic to reach the internal host using the 203.0.113.1 address, a random source port, and destination port 54311.
• C. Only the Internet host that the internal host originally communicated with can initiate traffic to reach the internal host using the 203.0 113.1 address, a random source port, and destination port 54311.
• D. Only the Internet host that the internal host originally communicated with can initiate traffic to reach the internal host using the 203.0.113.1 address, source port 54311, and a random destination port.

Answer: C

Explanation:
According to the Juniper documentation, reflexive NAT is a type of source NAT that allows an internal host to communicate with an external host using a single public IP address and port. The reflexive NAT session is created when the internal host initiates the traffic to the external host, and the session is deleted when the traffic stops. The reflexive NAT session is bidirectional, meaning that the external host can send traffic back to the internal host using the same public IP address and port that the internal host used to reach the external host. However, the external host cannot initiate a new session to the internal host using the same public IP address and port, unless the internal host has already established a session with the external host. Therefore, only the Internet host that the internal host originally communicated with can initiate traffic to reach the internal host using the 203.0.113.1 address, a random source port, and destination port 54311.

NEW QUESTION # 65
While troubleshooting security policies, you added the count action. Where do you see the result of this action?

• A. In the show security policies hit-count command output.
• B. In the show security policies detail command output.
• C. In the show security flow statistics command output.
• D. In the show firewall log command output.

Answer: B

Explanation:
The result of adding the count action to a security policy can be seen in the show security policies detail command output. The count action is a feature that allows you to enable statistics collection for sessions that enter the device for a given policy, and for the number of packets and bytes that pass through the device in both directions for a given policy. The count action can help you to monitor the traffic that matches a security policy and to troubleshoot security policy issues. The show security policies detail command displays the detailed information about the security policies configured on the device, including the count statistics. The output shows the number of packets and bytes that have been processed by the policy in both directions, as well as the number of sessions that have been created by the policy. You can use this command to verify that the count action is working as expected and to see the traffic volume and session count for each policy.

NEW QUESTION # 70
You want to enable inter-tenant communica􀆟on with tenant system.
In this Scenario, Which two solutions will accomplish this task?

• A. logical tunnel interface
• B. interconnect EVPN switch
• C. interconnect VPLS switch
• D. external router

Answer: A,D

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 # 71
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. Send a custom message
• C. Drop the connection silently.
• D. Close the connection.

Answer: A,D

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 # 72
You configure Source NAT using a pool of addresses that are in the same subnet range as the external ge-0/0/0 interface on your vSRX device. Traffic that is exiting the internal network can reach external destinations, but the return traffic is being dropped by the service provider router.
Referring to the exhibit, what must be enabled on the vSRX device to solve this problem?

• A. STUN

Answer: D

NEW QUESTION # 73
All interfaces involved in transparent mode are configured with which protocol family?

• A. bridge
• B. inet
• C. mpls
• D. ethernet - switching

Answer: A

Explanation:
In transparent mode, all interfaces involved are configured with the bridge protocol family. This allows the SRX device to act as a bridge between the interfaces and forward traffic transparently without any modification. The bridge interfaces can be configured to forward traffic based on layer 2 headers, such as MAC addresses, without the need for routing or IP addressing.
