* Access to the Cloud NGFW for AWS console: This access is crucial for the initial setup, configuration, and ongoing management of the Cloud NGFW resources. Terraform templates automate
* the provisioning and management of these resources, but initial access to the console is necessary to configure and retrieve necessary information (such as API keys and configuration details) for the Terraform scripts.
質問 # 35
Which two features of CN-Series firewalls protect east-west traffic between pods in different trust zones?
(Choose two.)
- A. Communication with Panorama
- B. External load balancer (ELB)
- C. Intrusion prevention system (IPS)
- D. Layer 7 visibility
正解：C、D
解説：
* 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.

解説：
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.
質問 # 38
What is the appropriate file format for Kubernetes applications?
- A. .exe
- B. Json
- C. .xml
- D. .yaml
正解：D
解説：
In Kubernetes, configuration files are typically written in YAML (.yaml) format. YAML (Yet Another Markup Language) is preferred due to its readability and ease of use for defining complex data structures like those required for Kubernetes deployments. Kubernetes uses these YAML files to define resources such as pods, services, and deployments.

質問 # 40
Why are VM-Series firewalls and hardware firewalls that are external to the Kubernetes cluster problematic for protecting containerized workloads?
- A. They do not scale independently of the Kubernetes cluster.
- B. They are managed by another entity when located inside the 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.
正解：D
解説：
* 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.

正解：A
解説：
Advanced URL Filtering (AURLF) leverages machine learning (ML) to provide real-time analysis and defense against new and unknown threats:
* Real-time analysis: AURLF uses ML models to analyze web traffic in real-time, identifying malicious URLs and preventing access to harmful content before it reaches the user.
* Defending against new and unknown threats: The ML capabilities allow the system to detect and block previously unknown threats by analyzing patterns and behaviors associated with malicious URLs, ensuring a proactive security posture.
質問 # 45
What do tags allow a VM-Series firewall to do in a virtual environment?
- A. Integrate with security information and event management (SIEM) solutions.
- B. Provide adaptive reporting.
- C. Enable machine learning (ML).
