Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q87-Q92):

NEW QUESTION # 87
Referring to the exhibit,

Which two statements are correct about the NAT configuration? (Choose two.)

  • A. The original destination port is used for the source port for the session.
  • B. Only a specific host can initiate a session to the reflexive address after the initial session.
  • C. Any external host will be able to initiate a session to the reflexive address.
  • D. Both the internal and the external host can initiate a session after the initial translation.

Answer: A,B

Explanation:
Persistent NAT with target-host restricts session initiation to specific addresses, enhancing security. Reflexive NAT supports multiple connections by preserving the original port.
Referring to the NAT configuration shown in the exhibit:
Specific Host Can Initiate a Session (Answer B): The configuration uses persistent NAT with the permit target-host-port statement. This allows a specific external host (based on the target host and port used in the initial session) to initiate a session back to the internal host after the initial session has been established.
Persistent NAT ensures that the translation state is maintained, allowing external hosts to connect back only under specific conditions (e.g., the same target host and port as used in the original connection).
Original Destination Port (Answer D): The original destination port used by the internal host is retained as the source port when the session is established from outside to inside. This behavior is a result of how persistent NAT binds the internal and external sessions, ensuring that communication occurs over the same port used for the initial session.


NEW QUESTION # 88
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 SRX Series firewalls to limit who has access
  • B. Enable Juniper ATP Cloud to share threat intelligence
  • C. Enable SRX Series firewalls to share Threat intelligence with third party tool.
  • D. Configure application tokens in the Juniper ATP Cloud to limit who has access

Answer: B,D

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 # 89
Exhibit:

Referring to the exhibit, which two statements are correct? (Choose two.)

  • A. The device cannot pass Layer 2 and Layer 3 traffic at the same time.
  • B. You cannot secure intra-VLAN traffic with a security policy on this device.
  • C. The device can pass Layer 2 and Layer 3 traffic at the same time.
  • D. You can secure inter-VLAN traffic with a security policy on this device.

Answer: C,D

Explanation:
The exhibit provides information about an SRX Series device operating intransparent mode(Layer 2) and Layer 3routing at the same time. Let's break down the correct answers:
* Explanation of Answer B (Secure Inter-VLAN Traffic with a Security Policy):
* The SRX device can secureinter-VLAN trafficbecause it supports security policies for Layer 3 traffic between different VLANs. In this case, traffic moving between different VLANs (i.e., Layer 3 traffic) can be processed and controlled using security policies.
* Explanation of Answer C (Pass Layer 2 and Layer 3 Traffic Simultaneously):
* The SRX device can handle both Layer 2 and Layer 3 traffic simultaneously. Inmixed mode, the device is capable of switching traffic at Layer 2 (intra-VLAN) while also routing traffic at Layer
3 (inter-VLAN). This is evident from the global configuration showingtransparent bridge mode and Layer 3 interfaces.
Juniper Security Reference:
* Mixed Mode Overview: Juniper SRX devices in mixed mode can operate as both a Layer 2 switch and a Layer 3 router, allowing it to pass traffic at both layers simultaneously. Reference: Juniper Mixed Mode Documentation.


NEW QUESTION # 90
Exhibit

You are using traceoptions to verify NAT session information on your SRX Series device.
Referring to the exhibit, which two statements are correct? (Choose two.)

  • A. This is the last packet in the session.
  • B. The SRX Series device is performing both source and destination NAT on this session.
  • C. The SRX Series device is performing only source NAT on this session.
  • D. This is the first packet in the session.

Answer: A,B


NEW QUESTION # 91
You need to set up source NAT so that external hosts can initiate connections to an internal device, but only if a connection to the device was first initiated by the internal device.
Which type of NAT solution provides this functionality?

  • A. Address persistence
  • B. Static NAT
  • C. Persistent NAT with any remote host
  • D. Persistent NAT with target host

Answer: D

Explanation:
Persistent NAT with target host allows external hosts to establish connections only when the internal device initiates a session first, ideal for specific interactive applications. Refer to Juniper Persistent NAT Documentation.
The scenario requires that external hosts be able to initiate a connection only if the internal device has already initiated a connection. The correct solution is Persistent NAT with target host, which ensures that a specific external host can initiate new connections back to the internal device, but only after the internal device has established a session first.
* Persistent NAT with Target Host (Answer C): This allows the internal device to initiate a connection, and once established, the specified external host can also initiate new connections to the internal device on the same NAT mapping.
Example Configuration:
bash
set security nat source persistent-nat permit target-host-port
This solution is appropriate when controlled bidirectional communication is required based on an internal- initiated connection.
