NEW QUESTION # 13
What is a design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment?
- A. Resources are shared within the cluster.
- B. High availability (HA) clusters are limited to fewer than 8 virtual appliances.
- C. Special AWS plugins are needed for load balancing.
- D. Only active-passive high availability (HA) is supported.
Answer: D
Explanation:
In AWS, VM-Series firewalls support only active-passive high availability (HA) configuration. This means that one firewall is active and processing traffic, while the other remains passive and takes over in the event of a failure. This design consideration ensures continuous availability and reliability of firewall services in the AWS environment.

NEW QUESTION # 14
Which technology allows for granular control of east-west traffic in a software-defined network?
- A. Routing
- B. MAC Access Control List
- C. Microsegmentation
- D. Virtualization
Answer: C
Explanation:
Microsegmentation is a security technique that enables granular control of east-west traffic within a software-defined network. By dividing the network into smaller segments, each with its own security policies, microsegmentation allows for detailed control over communication between workloads, thereby reducing the attack surface and preventing lateral movement of threats within the network.

NEW QUESTION # 22
Why are VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster problematic for protecting containerized workloads?
- A. They are managed by another entity when located inside the cluster.
- B. They do not scale independently of the Kubernetes cluster.
- C. They function differently based on whether they are located inside or outside of the cluster.
- D. They are located outside the cluster and have no visibility into application-level cluster traffic.
Answer: D
Explanation:
* Visibility into application-level cluster traffic:
* VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster lack the necessary visibility into the traffic and communications occurring at the application level within the cluster. This limitation impedes their ability to effectively protect containerized workloads.

NEW QUESTION # 26
Which two features of CN-Series firewalls protect east-west traffic between pods in different trust zones?
(Choose two.)
- A. Layer 7 visibility
- B. Communication with Panorama
- C. External load balancer (ELB)
- D. Intrusion prevention system (IPS)
Answer: A,D
Explanation:
* Intrusion Prevention System (IPS):The CN-Series firewalls incorporate an Intrusion Prevention System to detect and prevent exploits and attacks on applications and systems. This feature is essential for securing east-west traffic, as it can identify and block threats within the data center traffic between pods in different trust zones.
* Layer 7 Visibility:CN-Series firewalls provide Layer 7 (application layer) visibility, enabling deep inspection of application traffic. This allows the firewall to understand and enforce policies based on the application and its behavior, rather than just ports and protocols, ensuring comprehensive security for east-west traffic within a Kubernetes environment.

This hierarchy ensures that the configurations are organized logically, with Kubernetes-specific settings at the top level, followed by the type of deployment, and then the specific environment.
NEW QUESTION # 29
Why are containers uniquely suitable for runtime security based on allow lists?
- A. Operations teams know which processes are used within a container.
- B. Containers have only a few defined processes that should ever be executed.
- C. Docker has a built-in runtime analysis capability to aid in allow listing.
- D. Developers define the processes used in containers within the Dockerfile.
Answer: B
Explanation:
Containers are typically designed to run a specific application or service, meaning they have a limited and well-defined set of processes. This makes it easier to implement and manage runtime security based on allow lists, as any deviation from the expected processes can be quickly identified and mitigated.
Reference: Security best practices for container environments emphasize the use of allow lists to enforce runtime security, leveraging the predictable nature of container processes.

NEW QUESTION # 30
Which element protects and hides an internal network in an outbound flow?
- A. App-ID
- B. User-ID
- C. NAT
- D. DNS sinkholing
Answer: C
Explanation:
NAT (Network Address Translation) protects and hides an internal network in an outbound flow by translating internal private IP addresses to a public IP address. This process masks the internal IP addresses from external networks, providing security and privacy for the internal network. NAT is commonly used in outbound traffic to allow multiple devices on a local network to communicate with external networks while appearing as a single IP address.

- C. Select Network > Interfaces.
- D. Select the Config tab, then select New Route from the Security Zone Route drop-down menu.
Answer: A,B
Explanation:
To configure a default route to an internet router, you need to perform the following steps:
* Select Network > Virtual Router, then select the default link to open the Virtual Router dialog.
* Select the Static Routes tab, then click Add to create a new static route.
These steps ensure that the default route is correctly added to the virtual router configuration, allowing traffic to be directed to the appropriate internet gateway.

NEW QUESTION # 32
What does the number of required flex credits for a VM-Series firewall depend on?
- A. IP address allocation
- B. Network interface allocation
- C. Memory allocation
- D. vCPU allocation
Answer: D
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.

NEW QUESTION # 36
What helps avoid split brain in active-passive high availability (HA) pair deployment?
- A. Enabling preemption on both firewalls in the HA pair
- B. Using a standard traffic interface as the HA3 link
- C. Using the management interface as the HA1 backup link
- D. Using a standard traffic interface as the HA2 backup
Answer: C
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.

- C. It quarantines containers that demonstrate increased CPU and memory usage.
- D. It automatically builds an allow-list security model for every container and service.
Answer: D
Explanation:
Allow-list Security Model:
* Prisma Cloud Compute provides runtime security by automatically creating an allow-list security model for each container and service. This model ensures that only expected and authorized behaviors are allowed, effectively preventing unauthorized activities.
