Juniper Security, Professional (JNCIP-SEC) Sample Questions (Q95-Q100):

NEW QUESTION # 95
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. EX Series device
B. SRX Series device
C. Juniper ATP Appliance
D. Policy Enforcer

Answer: A,D

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.

NEW QUESTION # 96
You want to enable inter-tenant communicaon with tenant system.
In this Scenario, which two solutions will accomplish this task?

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

Answer: A,B

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 # 97
Which two statements are correct about automated threat mitigation with Security Director?(Choose two.)

A. Infected hosts are tracked by their MAC address.
B. Infected hosts are tracked by their user identity.
C. Infected hosts are tracked by their chassis serial number.
D. Infected hosts are tracked by their IP address.

Answer: B,D

Explanation:
Security Director provides an integrated security management solution for Juniper devices, including SRX Series Firewalls. Automated threat mitigation refers to the system's capability to react dynamically to security incidents such as malware infections, based on predefined policies. Let's dive into the details behind each selected option:
* IP Address Tracking (Correct: Option A):Infected hosts are tracked by their IP address because the firewall and threat mitigation systems use the IP address as a key identifier for network traffic and routing. IP addresses are fundamental in identifying which device on the network is exhibiting malicious behavior. Security Director can automatically track and block these infected hosts using their IP addresses by correlating threat logs and incident data with a specific device's network activities.
* User Identity Tracking (Correct: Option D):Security Director integrates with identity management solutions and LDAP directories to correlate security incidents with specific user identities. This capability allows the security system to track threats not only by device but also by the authenticated user currently associated with that device. This feature is particularly useful in environments where multiple users share devices, or where network access is granted based on user credentials.
Now, let's discuss why the other options are incorrect:
* MAC Address Tracking (Incorrect: Option C):While MAC addresses can be used for identifying devices on the same local network, they are not a primary tracking method for infected hosts in the broader network managed by Security Director. MAC addresses are not visible once traffic passes through routers since Layer 2 information is stripped off. Therefore, Juniper's automated threat mitigation focuses more on IP and user identity tracking rather than MAC addresses.
* Chassis Serial Number Tracking (Incorrect: Option B):Tracking infected hosts by chassis serial number is not a common practice in automated threat mitigation. Serial numbers are primarily used for inventory and hardware management purposes, rather than for identifying infected hosts or mitigating threats in real time.
Juniper References:
* Juniper Security Director Documentation explains how IP addresses and user identities are tracked for threat mitigation, highlighting the importance of dynamic response based on these identifiers.
* Security Director supports dynamic blocklists and real-time mitigation strategies based on both IP and user-based tracking, leveraging integration with Active Directory (AD) or LDAP for identity-based policies.

NEW QUESTION # 98
You are asked to see if your persistent NAT binding table is exhausted. Which show command would you use to accomplish this task?

A. show security nat source persistent-nat-table summary
B. show security nat source summary
C. show security nat source persistent-nat-table all
D. show security nat source pool all

Answer: C

Explanation:
The command show security nat source persistent-nat-table all provides a comprehensive view of all entries in the persistent NAT table, enabling administrators to monitor and manage resource exhaustion.
In Junos OS, when persistent NAT is configured, a binding table is created to keep track of NAT sessions and ensure that specific hosts are allowed to initiate sessions back to internal hosts. To check if the persistent NAT binding table is full or exhausted, the correct command must display the entire table.
The command show security nat source persistent-nat-table all will display the entire persistent NAT binding table. This allows you to check whether the table is exhausted or if there is space available for new persistent NAT sessions.
