NEW QUESTION # 36
Which two statements are correct about automated threat mitigation with Security Director?(Choose two.)
- A. Infected hosts are tracked by their IP address.
- B. Infected hosts are tracked by their MAC address.
- C. Infected hosts are tracked by their user identity.
- D. Infected hosts are tracked by their chassis serial number.
Answer: A,C
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 # 38
Exhibit:
You have deployed a pair of SRX series devices in a multimode HA environment. You need to enable IPsec encryption on the interchassis link.
Referring to the exhibit, which three steps are required to enable ICL encryption? (Choose three.)
- A. Install the Junos IKE package on both nodes.
- B. Enable HA link encryption in the IKE profile on both nodes,
- C. Enable OSPF for both interchassis link interfaces and tum on the dynamic-neighbors parameter.
- D. Configure a VPN profile for the HA traffic and apply to both nodes.
- E. Enable HA link encryption in the IPsec profile on both nodes.
Answer: A,D,E
Explanation:
A: Install the Junos IKE package on both nodes. While I previously stated that IKE is usually included in the base Junos OS image, it's essential to ensure that the necessary IKE package is indeed installed and enabled on both SRX nodes to support ICL encryption. C. Configure a VPN profile for the HA traffic and apply it to both nodes. This dedicated VPN profile defines the security parameters (encryption algorithms, authentication, etc.) specifically for the ICL traffic.

NEW QUESTION # 41
Referring to the exhibit,
which two statements about User1 are true? (Choose two.)
- A. User1 can add logical units to an interface that a primary administrator has not previously assigned.
- B. User1 has access to the configuration specific to their assigned logical system.
- C. User1 can view outputs from other user logical systems.
- D. User1 is logged in to logical system LSYS-1.
Answer: B,D
Explanation:
In this configuration, User1 is logged into logical system LSYS-1, which restricts access and visibility to that particular system. This ensures isolation between logical systems on the same physical device. Only a system administrator can assign additional permissions. For more details, see Juniper Logical Systems Guide.
From the exhibit, we see that User1 is logged into logical system LSYS-1:
* Access to Assigned Logical System (Answer A): User1, being logged into the logical system LSYS-1, only has access to the configuration and interfaces within that logical system. This is a key feature of logical systems in Junos, ensuring users are restricted to their respective environments.
* Logged into LSYS-1 (Answer B): The prompt shows that User1 is currently operating in LSYS-1, as indicated by the User1@SRX:LSYS-1> command line.
NEW QUESTION # 42

NEW QUESTION # 43
Exhibit:
Referring to the exhibit, what do you use to dynamically secure traffic between the Azure and AWS clouds?
- A. You can dynamically secure traffic between the clouds by using URL filtering in the security policies.
- B. You can dynamically secure traffic between the clouds by using advanced connection tracking in the security policies.
- C. You can dynamically secure traffic between the clouds by using user identities in the security policies.
- D. You can dynamically secure traffic between the clouds by using security tags in the security policies.
Answer: D
Explanation:
Security tags facilitate dynamic traffic management between cloud environments like Azure and AWS. Tags allow flexible policies that respond to cloud-native events or resource changes, ensuring secure inter-cloud communication. For more information, see Juniper Cloud Security Tags.
In the scenario depicted in the exhibit, where traffic needs to be dynamically secured between Azure and AWS clouds, the best method to achieve dynamic security is by using security tags in the security policies.
Security tags allow dynamic enforcement of security policies based on metadata rather than static IP addresses or zones. This is crucial in cloud environments, where resources and IP addresses can change dynamically.
Using security tags in the security policies, you can associate traffic flows with specific applications, services, or virtual machines, regardless of their underlying IP addresses or network locations. This ensures that security policies are automatically updated as cloud resources change.
NEW QUESTION # 44

NEW QUESTION # 45
Exhibit:
Your company uses SRX Series devices to establish an IPsec VPN that connects Site-1 and the HQ networks.
You want VoIP traffic to receive priority over data traffic when it is forwarded across the VPN.
Which three actions should you perform in this scenario? (Choose three.)
- A. Enable the copy-outer-dscp parameter so that DSCP header values are copied to the tunneled packets.
- B. Enable next-hop tunnel binding.
- C. Configure CoS forwarding classes and scheduling parameters.
- D. Create a firewall filter that identifies VoIP traffic and associates it with the correct forwarding class.
- E. Enable the multi-sa parameter to enable two separate IPsec SAs for the VoIP and data traffic.
Answer: B,C,D
Explanation:
In this scenario, you are prioritizing VoIP traffic over data traffic across an IPsec VPN. Here are the necessary actions:
* Enable next-hop tunnel binding (Answer A): This is required to bind the VPN traffic to a specific tunnel interface (like st0.0). It allows differentiated forwarding behavior (like prioritizing VoIP) for specific traffic types.
Command Example:
bash
Copy code
set interfaces st0.0 next-hop-tunnel-service
* Create a firewall filter (Answer B): The filter will match VoIP traffic based on criteria such as DSCP marking or ports (like port 5060 for SIP). Once identified, the traffic will be associated with a forwarding class, ensuring it gets prioritized.
Command Example:
bash
Copy code
set firewall family inet filter VoIP-Filter term VoIP from protocol udp set firewall family inet filter VoIP-Filter term VoIP from port 5060 set firewall family inet filter VoIP-Filter term VoIP then forwarding-class voice
* Configure CoS (Class of Service) forwarding classes (Answer C): CoS parameters define how the SRX handles different types of traffic (scheduling, shaping, etc.). VoIP traffic must be assigned a higher priority than data.
Command Example:
bash
Copy code
set class-of-service forwarding-classes voice
set class-of-service forwarding-classes data
set class-of-service schedulers voice_scheduler transmit-rate percent 50 These configurations ensure that VoIP traffic is identified, classified, and forwarded with priority.

NEW QUESTION # 50
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. Any external host will be able to initiate a session to the reflexive address.
- C. Both the internal and the external host can initiate a session after the initial translation.
- D. Only a specific host can initiate a session to the reflexive address after the initial session.
Answer: A,D
Explanation:
Persistent NAT with target-host restricts session initiation to specific addresses, enhancing security. Reflexive NAT supports multiple connections by preserving the original port. Refer to Juniper NAT Configuration Documentation.
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.
Explanation: 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 # 54
Which two statements are correct about the ICL in an active/active mode multinode HA environment?
(Choose two.)
- A. The ICL uses a separate routing instance to communicate with remote multinode HA peers.
- B. The ICL traffic can be encrypted.
- C. The ICL is the local device management interface in a multinode HA environment.
- D. The ICL is strictly a Layer 2 interface.
Answer: B,D
Explanation:
In an active/active HA environment, the Interchassis Link (ICL) is used primarily for Layer 2 communication between nodes. Encrypting the ICL traffic can enhance security as it carries critical HA state synchronization data. More details can be found in the Juniper HA Documentation.
In an active/active mode multinode HA (High Availability) setup, the Inter-Chassis Link (ICL) plays a crucial role in connecting SRX Series devices to ensure synchronized operation. Here are the key details:
* Layer 2 Interface (Answer A): The ICL operates as a Layer 2 interface, facilitating direct communication between the SRX devices in the HA cluster. This interface is essential for synchronizing session information, firewall states, and configuration data across the devices.
* ICL Traffic Encryption (Answer C): For security purposes, the traffic that passes through the ICL can be encrypted. This is particularly important in environments where the ICL traverses insecure or untrusted networks, ensuring that synchronization data, including session states and configurations, is protected from interception.
To configure encryption on ICL, use Junos OS commands to establish secure communication channels and IPsec tunnels if necessary, depending on the network design.
