NEW QUESTION # 53
Exhibit:

Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated Ip address list to the SRX.
Which three actions are required to complete the requirement? (Choose three)

A. Configure Security Director to create a dynamic address feed
B. Create a security policy that uses the dynamic address feed to allow access
C. Configure server feed URL as https://172.25.10.254/myprinters.
D. Configure Security Director to create a C&C feed.
E. Configure the server feed URL as http://172.25.10.254/myprinters

Answer: A,B,E

Explanation:
Referring to the exhibit, your company's infrastructure team implemented new printers. To make sure that the policy enforcer pushes the updated IP address list to the SRX, you need to perform the following actions:
A) Configure the server feed URL as http://172.25.10.254/myprinters. The server feed URL is the address of the remote server that provides the custom feed data. You need to configure the server feed URL to match the location of the file that contains the IP addresses of the new printers. In this case, the file name is myprinters and the server IP address is 172.25.10.254, so the server feed URL should be
http://172.25.10.254/myprinters1.
B) Create a security policy that uses the dynamic address feed to allow access. 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 need to create a security policy that uses the dynamic address feed as the source or destination address to allow access to the new printers. A dynamic address feed is a custom feed that contains a group of IP addresses that can be entered manually or imported from external sources. The dynamic address feed can be used in security policies to either deny or allow traffic based on either source or destination IP criteria2.
C) Configure Security Director to create a dynamic address feed. Security Director is a Junos Space application that enables you to create and manage security policies and objects. You need to configure Security Director to create a dynamic address feed that contains the IP addresses of the new printers.
You can create a dynamic address feed by using the local file or the remote file server option. In this case, you should use the remote file server option and specify the server feed URL as
http://172.25.10.254/myprinters3.
The other options are incorrect because:
D) Configuring Security Director to create a C&C feed is not required to complete the requirement. A C&C 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 C&C feed is not related to the new printers or the dynamic address feed.
E) Configuring the server feed URL as https://172.25.10.254/myprinters is not required to complete the requirement. The server feed URL can use either the HTTP or the HTTPS protocol, depending on the configuration of the remote server. In this case, the exhibit shows that the remote server is using the HTTP protocol, so the server feed URL should use the same protocol1.

NEW QUESTION # 54
Exhibit

Referring to the exhibit, which type of NAT is being performed?

A. Persistent NAT
B. Static NAT
C. Destination NAT
D. Source NAT

Answer: D

NEW QUESTION # 55
You are asked to share threat intelligence from your environment with third party tools so that those tools can be identify and block lateral threat propagation from compromised hosts.
Which two steps accomplish this goal? (Choose Two)

A. Configure application tokens in the Juniper ATP Cloud to limit who has access
B. Enable SRX Series firewalls to share Threat intelligence with third party tool.
C. Enable Juniper ATP Cloud to share threat intelligence
D. Configure application tokens in the SRX Series firewalls to limit who has access

Answer: A,C

Explanation:
To share threat intelligence from your environment with third party tools, you need to enable Juniper ATP Cloud to share threat intelligence and configure application tokens in the Juniper ATP Cloud to limit who has access. The other options are incorrect because:
A) Configuring application tokens in the SRX Series firewalls is not necessary or sufficient to share threat intelligence with third party tools. Application tokens are used to authenticate and authorize requests to the Juniper ATP Cloud API, which can be used to perform various operations such as submitting files, querying C&C feeds, and managing allowlists and blocklists1. However, to share threat intelligence with third party tools, you need to enable the TAXII service in the Juniper ATP Cloud, which is a different protocol for exchanging threat information2.
D) Enabling SRX Series firewalls to share threat intelligence with third party tools is not possible or supported. SRX Series firewalls 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 traffic3.
However, SRX Series firewalls cannot directly share threat intelligence with third party tools. You need to use the Juniper ATP Cloud as the intermediary for threat intelligence sharing. Therefore, the correct answer is B and C. You need to enable Juniper ATP Cloud to share threat intelligence and configure application tokens in the Juniper ATP Cloud to limit who has access.
To do so, you need to perform the following steps:
Enable and configure the TAXII service in the Juniper ATP Cloud. TAXII (Trusted Automated eXchange of Indicator Information) is a protocol for communication over HTTPS of threat information between parties.
STIX (Structured Threat Information eXpression) is a language used for reporting and sharing threat information using TAXII. Juniper ATP Cloud can contribute to STIX reports by sharing the threat intelligence it gathers from file scanning. Juniper ATP Cloud also uses threat information from STIX reports as well as other sources for threat prevention2. To enable and configure the TAXII service, you need to select Configure > Threat Intelligence Sharing in the Juniper ATP Cloud WebUI, move the knob to the right to Enable TAXII, and move the slidebar to designate a file sharing threshold2. Configure application tokens in the Juniper ATP Cloud. Application tokens are used to authenticate and authorize requests to the Juniper ATP Cloud API and the TAXII service. You can create and manage application tokens in the Juniper ATP Cloud WebUI by selecting Configure > Application Tokens. You can specify the name, description, expiration date, and permissions of each token. You can also revoke or delete tokens as needed. You can use the application tokens to limit who has access to your shared threat intelligence by granting or denying permissions to the TAXII service1.

NEW QUESTION # 56
Exhibit:

You are configuring NAT64 on your SRX Series device. You have committed the configuration shown in the exhibit. Unfortunately, the communication with the 10.10.201.10 server is not working. You have verified that the interfaces, security zones, and security policies are all correctly configured.
In this scenario, which action will solve this issue?

A. Configure proxy-NDP on the IPv6 interface for the 2001:db8::1/128 address.
B. Configure source NAT to translate return traffic from IPv4 address to the IPv6 address of your source device.
C. Configure proxy-ARP on the external IPv4 interface for the 10.10.201.10/32 address.
D. Configure destination NAT to translate return traffic from the IPv4 address to the IPv6 address of your source device.

Answer: B

Explanation:
In the scenario described, you are configuring NAT64, which allows communication between IPv6 and IPv4 networks by translating IPv6 packets to IPv4 and vice versa. The configuration in the exhibit shows an attempt to translate traffic coming from the IPv6 address 2001:db8::1/128 and destined for the IPv4 address
10.10.201.10/32.
However, the issue here is related to the return traffic. For NAT64 to function correctly, you must ensure that the return traffic (from the IPv4 network) is translated back to the original IPv6 source address. Without proper translation of the return traffic, the communication will not be successful. In this case, you needsource NATto handle the return traffic correctly.
Detailed Solution:
* In NAT64, when traffic originates from an IPv6 network and is translated to IPv4, the return traffic from the IPv4 network must be translated back to the original IPv6 address usingsource NAT.
* The source NAT configuration must include translation for the return path from IPv4 to IPv6 to ensure bidirectional communication.
Configuration Example:
To resolve the issue, you can configure source NAT on the SRX device to handle the translation of the return traffic as follows:
* Configure Source NAT for Return Traffic:You need to configure source NAT on the interface handling the return traffic. This will translate the IPv4 address back to the IPv6 source address.
Example:
bash
Copy code
set security nat source rule-set ipv4-source-rule from zone untrust
set security nat source rule-set ipv4-source-rule to zone trust
set security nat source rule-set ipv4-source-rule rule source-nat-translation match source-address 10.10.201.10
/32
set security nat source rule-set ipv4-source-rule rule source-nat-translation then source-nat pool ipv6-source- pool
* Ensure Proper Routing and Security Policy Configuration:Make sure that both the IPv4 and IPv6 routes are correctly defined, and that security policies are allowing the return traffic through.
Use the following commands to verify the NAT and policy configurations:
bash
Copy code
show security nat source
show security policies
By configuring source NAT to translate the return traffic back to IPv6, the communication between the IPv6 host and the IPv4 server should now work correctly.
Juniper Security Reference:
* NAT64 Overview: This functionality allows IPv6 clients to communicate with IPv4-only servers. For successful translation, NAT64 requires both source NAT and destination NAT to handle the bidirectional traffic. Reference: Juniper Networks Documentation on NAT64.
