QUESTION: 25

What are two environments supported by the CN-Series firewall? (Choose two.)

Positive K
OpenShift
OpenStack
Native K8

Answer(s): B,D

Explanation:

The two environments supported by the CN-Series firewall are:
OpenShift
Native K8
The CN-Series firewall is a containerized firewall that integrates with Kubernetes and provides visibility and control over container traffic. The CN-Series firewall can be deployed in various environments that support Kubernetes, such as public clouds, private clouds, or on-premises data centers. OpenShift is an environment supported by the CN-Series firewall. OpenShift is a platform that provides enterprise-grade Kubernetes and container orchestration, as well as developer tools and services. Native K8 is an environment supported by the CN-Series firewall. Native K8 is a term that refers to the standard Kubernetes distribution that is available from the Kubernetes project website, without any vendor-specific modifications or additions. Positive K and OpenStack are not environments supported by the CN-Series firewall, but they are related concepts that can be used for other purposes.

QUESTION: 26

Why are VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster problematic for protecting containerized workloads?

They are located outside the cluster and have no visibility into application-level cluster traffic.
They do not scale independently of the Kubernetes cluster.
They are managed by another entity when located inside the cluster.
They function differently based on whether they are located inside or outside of the cluster.

Answer(s): A

Explanation:

VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster are problematic for protecting containerized workloads because they are located outside the cluster and have no visibility into application-level cluster traffic. Kubernetes is a platform that provides orchestration, automation, and management of containerized applications. Kubernetes cluster traffic consists of traffic between containers within a pod, across pods, or across namespaces. VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster cannot inspect or control this traffic, as they only see the encapsulated or aggregated traffic at the network layer. This creates blind spots and security gaps for containerized workloads. VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster are not problematic for protecting containerized workloads because they do not scale independently of the Kubernetes cluster, are managed by another entity when located inside the cluster, or function differently based on whether they are located inside or outside of the cluster, as those are not valid reasons or scenarios for firewall deployment in a Kubernetes environment.

QUESTION: 27

What is a benefit of network runtime security?

It more narrowly focuses on one security area and requires careful customization integration and maintenance
It removes vulnerabilities that have been baked into containers.
It is siloed to enhance workload security.
It identifies unknown vulnerabilities that cannot be identified by known Common Vulnerability and Exposure (CVE) lists.

Answer(s): D

Explanation:

A benefit of network runtime security is that it identifies unknown vulnerabilities that cannot be identified by known Common Vulnerability and Exposure (CVE) lists. Network runtime security is a type of security that monitors and analyzes network traffic in real time to detect and prevent malicious activities or anomalous behaviors. Network runtime security can identify unknown vulnerabilities that cannot be identified by known CVE lists, such as zero-day exploits, advanced persistent threats, or custom malware. Network runtime security can also provide visibility and context into network activity, such as application dependencies, user identities, device types, or threat intelligence. Network runtime security does not more narrowly focus on one security area and requires careful customization, integration, and maintenance, remove vulnerabilities that have been baked into containers, or is siloed to enhance workload security, as those are not benefits or characteristics of network runtime security.

QUESTION: 28

What is a design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment?

Special AWS plugins are needed for load balancing.
Resources are shared within the cluster.
Only active-passive high availability (HA) is supported.
High availability (HA) clusters are limited to fewer than 8 virtual appliances.

Answer(s): C

Explanation:

A design consideration for a prospect who wants to deploy VM-Series firewalls in an Amazon Web Services (AWS) environment is that only active-passive high availability (HA) is supported. High availability (HA) is a feature that provides redundancy and failover protection for firewalls in case of hardware or software failure. Active-passive HA is a mode of HA that consists of two firewalls in a pair, where one firewall is active and handles all traffic, while the other firewall is passive and acts as a backup. Active-passive HA is the only mode of HA that is supported for VM-Series firewalls in an AWS environment, due to the limitations of AWS networking and routing. Active-active HA, which is another mode of HA that consists of two firewalls in a pair that both handle traffic and synchronize sessions, is not supported for VM-Series firewalls in an AWS environment. A design consideration for a prospect who wants to deploy VM-Series firewalls in an AWS environment is not that special AWS plugins are needed for load balancing, resources are shared within the cluster, or high availability (HA) clusters are limited to fewer than 8 virtual appliances, as those are not valid or relevant factors for firewall deployment in an AWS environment.
