NEW QUESTION # 15
A customer in a VMware ESXi environment wants to add a VM-Series firewall and partition an existing group of virtual machines (VMs) in the same subnet into two groups. One group requires no additional security, but the second group requires substantially more security.
How can this partition be accomplished without editing the IP addresses or the default gateways of any of the guest VMs?
- A. Edit the IP address of all of the affected VMs.
- B. Create a Layer 3 interface in the same subnet as the VMs and then configure proxy Address Resolution Protocol (ARP).
- C. Send the VLAN out of the virtual environment into a hardware Palo Alto Networks firewall in Layer 3 mode. Use the same IP address as the old default gateway, then delete it.
- D. Create a new virtual switch and use the VM-Series firewall to separate virtual switches using virtual wire mode. Then move the guests that require more security into the new virtual switch.
Answer: D
Explanation:
Creating a New Virtual Switch:
* By creating a new virtual switch, you can segment the network within the ESXi environment. The VM-Series firewall can then be used to provide security controls between these virtual switches using virtual wire mode.
NEW QUESTION # 16
Which feature provides real-time analysis using machine learning (ML) to defend against new and unknown threats?
- A. Advanced URL Filtering (AURLF)
- B. DNS Security

NEW QUESTION # 19
Which two methods of Zero Trust implementation can benefit an organization? (Choose two.)
- A. Compliance is validated.
- B. Boundaries are established.
- C. Security automation is seamlessly integrated.
- D. Access controls are enforced.
Answer: C,D
Explanation:
Zero Trust implementation revolves around the principle that no entity, inside or outside the network, should be trusted by default. The primary methods that benefit an organization are:
* Security automation is seamlessly integrated: Zero Trust requires continuous monitoring and verification of every device and user attempting to access resources. Automation helps in efficiently managing these processes, ensuring that security policies are consistently enforced without human error.
Automated tools can quickly detect anomalies, respond to threats, and update access controls dynamically.
NEW QUESTION # 20
How does a CN-Series firewall prevent exfiltration?
- A. It inspects outbound traffic content and blocks suspicious activity.
- B. It distributes incoming virtual private cloud (VPC) traffic across the pool of VM-Series firewalls.
- C. It provides a license deactivation API key.
- D. It employs custom-built signatures based on hash.
Answer: C
Explanation:
The CN-Series firewall prevents data exfiltration by inspecting the content of outbound traffic. It uses advanced security features, such as threat prevention and data loss prevention (DLP), to detect and block suspicious activities and unauthorized data transfers, ensuring sensitive data remains within the secure environment.

NEW QUESTION # 21
Which solution is best for securing an EKS environment?
- A. CN-Series high availability (HA) pair
- B. PA-Series using load sharing
- C. API orchestration
- D. VM-Series single host
Answer: A
Explanation:
CN-Series for EKS Security:
* The CN-Series firewalls are specifically designed to secure Kubernetes environments, such as Amazon EKS. Deploying them in a high availability (HA) pair ensures robust, fault-tolerant security for containerized workloads, providing continuous protection and high availability.
NEW QUESTION # 22
What helps avoid split brain in active-passive high availability (HA) pair deployment?
- A. Using the management interface as the HA1 backup link
- B. Using a standard traffic interface as the HA3 link
- C. Using a standard traffic interface as the HA2 backup
- D. Enabling preemption on both firewalls in the HA pair
Answer: A
Explanation:
To avoid split brain scenarios in an active-passive high availability (HA) pair deployment, the management interface can be used as the HA1 backup link. This ensures reliable communication between the HA pair and prevents both firewalls from assuming the active role simultaneously, which can happen if they lose connectivity with each other on the primary HA1 link.

NEW QUESTION # 26
What does the number of required flex credits for a VM-Series firewall depend on?
- A. Network interface allocation
- B. vCPU allocation
- C. Memory allocation
- D. IP address allocation
Answer: B
Explanation:
The number of required flex credits for a VM-Series firewall primarily depends on the vCPU allocation. Flex credits are used to license VM-Series firewalls, and the number of credits required is determined by the number of virtual CPUs (vCPUs) allocated to the firewall. Higher vCPU allocations provide greater performance capabilities and thus require more flex credits.
