Important Palo Alto Networks Cybersecurity-Apprentice Exam Questions

Answer: C

Explanation:

SD-WAN provides centralized, software-defined control over wide area network connectivity. A major benefit is that administrators can create and deploy policies across many sites consistently, rather than manually configuring each traditional WAN device in isolation. SD-WAN can use multiple transport types, such as broadband, LTE, internet, and MPLS, so it does not remove reliance on diverse connection types; it manages them more intelligently. It also does not mean all physical WAN components disappear. Physical links, edge devices, and provider circuits still exist, but the control and policy model becomes more centralized and flexible. Electromagnetic interference is unrelated to the primary value of SD-WAN. SD-WAN is useful because it can steer application traffic based on performance, cost, availability, or security requirements. For security teams, centralized policy helps reduce configuration drift and supports consistent connectivity decisions across branches and cloud environments.

Answer: C

Explanation:

A HIDS directly integrates with an endpoint or host and monitors activity on that system. It can evaluate logs, file changes, processes, authentication activity, configuration changes, and local indicators that may not be visible on the network. This makes it a last line of defense because it can detect suspicious activity after traffic has reached the host or when malicious activity occurs locally. A NIDS monitors traffic on a network segment rather than being installed on each individual endpoint. Answer A incorrectly describes network-based detection as endpoint-installed. Answer B is awkwardly worded and less precise than answer C. Answer D incorrectly assigns endpoint integration to NIDS. HIDS and NIDS are complementary. NIDS provides broad network visibility, while HIDS provides deep host-level visibility. Security teams use both types of telemetry to understand attack scope and confirm whether suspicious network behavior resulted in endpoint compromise.

Answer: C

Explanation:

A VPN is created to encrypt data for secure transport across an untrusted or shared network. It establishes a protected tunnel between endpoints, users, sites, or networks so that traffic is less exposed to interception or tampering. Blocking malicious traffic is primarily the role of firewalls, IPS, secure web gateways, or other enforcement controls. Reducing traffic overhead is not the purpose of VPN; encryption can actually add overhead. Automating and correlating incidents is a SOAR or SIEM function, not VPN. VPNs are commonly used for remote user access and site-to-site connectivity. They can protect sensitive business communication between branch offices, cloud networks, and corporate resources. However, VPNs are not a complete security architecture by themselves. Strong authentication, access control, logging, least privilege, device posture validation, and segmentation are still necessary to ensure that encrypted access is also authorized and monitored.

Answer: A

Explanation:

A container is a self-sufficient executable package that includes application code and the dependencies needed to run consistently across environments. Containers usually package code, runtime, libraries, and system tools, while sharing the underlying host operating system kernel. This makes them lighter and faster to start than virtual machines. A host is the physical or virtual system that runs workloads. A server provides services to clients, but the term does not specifically describe packaged application dependencies. A virtual machine is a full isolated operating environment with its own guest OS, making it heavier than a container. Containers are central to cloud-native application design because they support portability, scalability, microservices, and automated deployment. From a security perspective, containers must be scanned for vulnerabilities, configured securely, run with least privilege, and monitored at runtime. Container security also depends on image integrity, registry controls, orchestration policy, and secrets handling.

Answer: D

Explanation:

Least privilege means users, services, and systems receive only the permissions required to perform their legitimate duties. This reduces risk because a compromised account or misused identity has a smaller blast radius. For example, an employee who only needs to read reports should not have administrator rights to modify databases or deploy code. Temporary access may be part of just-in-time access, but providing temporary access to all users is not least privilege. Granting permission to all resources is the opposite of least privilege. Giving every user the same access level may simplify administration, but it creates excessive privilege and increases exposure. Least privilege should be enforced through IAM policies, RBAC, privileged access management, access reviews, and strong authentication. It is one of the most important identity security principles because many breaches become severe only after attackers obtain accounts with broader permissions than necessary.
