CNX-001 Exam Dumps - CompTIA CloudNetX Exam

Comprehensive and Detailed Explanation From Exact Extract:

When building infrastructure for business units that process financial transactions (such as in the retail or banking sector), the architect must first understand all relevant compliance and regulatory requirements. These may include PCI DSS, SOX, or GDPR, depending on the nature of the data and jurisdiction. These regulations influence design decisions regarding encryption, segmentation, data retention, and logging.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Compliance and Regulatory Considerations”:

“Regulatory requirements such as PCI DSS, HIPAA, and others dictate the security controls, logging, data protection, and architectural design of infrastructure handling sensitive or financial data.”

Other options:

B. Statement of Work defines project scope, but doesn't include legal/compliance mandates.

C. Business case studies illustrate value or ROI, not security or compliance needs.

D. Internal reference architectures may help with standards but are based on already defined requirements.

RADIUS (Remote Authentication Dial-In User Service) is the best-fit protocol for this requirement. It supports both authentication and authorization and is widely used in Wi-Fi network environments for client device authentication using credentials stored in centralized directories such as Active Directory.

RADIUS integrates seamlessly with enterprise authentication sources and supports EAP (Extensible Authentication Protocol), making it compatible with Wi-Fi-based client devices. It also allows for role-based access control, enabling policy enforcement specific to device types (e.g., inventory scanners).

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — “Authentication and Authorization Technologies”:

“RADIUS provides centralized authentication, authorization, and accounting (AAA) services and is commonly used for securing wireless access in conjunction with Active Directory.”

“Organizations use RADIUS to manage Wi-Fi authentication for user devices and enforce security policies during access attempts.”

Using a RADIUS server with 802.1X on the Wi-Fi infrastructure allows the scanners (and their users) to be authenticated against Active Directory and mapped to the correct authorization policies. TACACS+ is geared toward device management, LDAP alone doesn’t handle the Wi-Fi 802.1X handshake, and PKI by itself wouldn’t provide the user-to-device authorization flow needed. RADIUS gives you both authentication and authorization tied into AD.

To accommodate 200 devices in IT and 2,000 devices in Sales, subnetting must allow for appropriate address allocation:

/22 provides 1,024 addresses → sufficient for IT (200 users)

/15 provides 65,536 addresses → more than sufficient for Sales (2,000 users)

Option C ensures both departments are placed in separate, appropriately sized segments within the private 10.0.0.0/8 range.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “IP Addressing and Subnetting”:

“Proper subnetting ensures sufficient host addresses and supports future growth. Network segmentation improves manageability and security.”

Other options:

A. /30 provides only 2 usable IPs — insufficient for IT.

B & D: /24 and /25 do not support 2,000 users in Sales.

B & D also misallocate resources inefficiently.

Comprehensive and Detailed Explanation From Exact Extract:

Weighted load balancing allows distribution of traffic based on server capacity or assignedweights. In this case, the new node should receive a weight of 3, and each of the three older nodes a weight of 1. This ensures the new node handles the same total number of requests as the other three combined (3:1:1:1).

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Load Balancing Algorithms and Traffic Distribution”:

“Weighted load balancing accounts for node capacity, distributing requests proportionally according to performance capability or administrator-defined weights.”

Other options:

A. Round-robin sends traffic equally to all servers regardless of capacity.

B. Load-based requires dynamic performance measurement and is more complex.

C. Least connections may work in certain cases, but doesn’t guarantee proportional traffic split based on server performance.

================================================

Comprehensive and Detailed Explanation From Exact Extract:

Round-robin DNS is a simplistic form of load balancing that does not perform health checks. If one of the four servers is down, DNS will still resolve its IP to 25% of users, resulting in failed connections. This matches the symptom of 25% failure rate — 1 out of 4.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Load Balancing Techniques and Availability”:

“Round-robin DNS distributes requests without regard for health status. Without external health checks, failed servers will continue to receive traffic, leading to partial service disruptions.”

Other options:

B. The percentages do not align with a 25% failure rate.

C. Least-connection algorithms usually have integrated health checks.

D. If health checks are active, the load balancer would not forward requests to a failed server.

Comprehensive and Detailed Explanation From Exact Extract:

ipconfig /all on a Windows machine displays detailed network configuration, including the MACaddress (referred to as “Physical Address”) of the device’s network adapter. This is the most direct and accurate method for obtaining the MAC address of the device you are operating.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Device Identification and MAC Filtering”:

“MAC addresses can be identified locally using interface configuration tools such as ipconfig /all on Windows or ifconfig/ip on Linux.”

Other options:

B. netstat shows open network connections, not MAC addresses.

C. arp -a shows MAC addresses of other devices in the ARP cache, not the local system.

D. nslookup queries DNS records and doesn’t display MAC information.

Comprehensive and Detailed Explanation From Exact Extract:

A private service endpoint allows the API to be exposed securely to a customer’s Virtual Private Cloud (VPC) without making it publicly accessible over the internet. This enables secure, private communication over the cloud provider’s backbone network while maintaining isolation and control over API access.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Cloud Networking and Connectivity”:

“Private service endpoints allow secure communication between cloud resources and customer environments without traversing the public internet, reducing exposure and enhancing compliance.”

This method is essential for SaaS providers aiming to securely integrate services with customer environments.

Other options:

A. Transit gateways provide large-scale connectivity but are more suited for multi-VPC or hybrid cloud environments.

B. Firewall rules alone do not restrict access to private-only networks.

C. VPC peering can work, but private endpoints are designed specifically for service-to-service communication.

Comprehensive and Detailed Explanation From Exact Extract:

Data Loss Prevention (DLP) solutions scan messages and file transfers for sensitive data patterns, such as credit card numbers or social security numbers. DLP can block, log, or alert when such information is detected attempting to leave the organization.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “Data Protection and Compliance Controls”:

“DLP systems identify and restrict the transmission of sensitive data such as credit card numbers, enforcing organizational data handling policies.”

Other options:

A. IDS detects threats but doesn’t enforce data content policies.

B. Egress filtering restricts destinations but not content.

D. Encryption protects data in transit, not its content compliance.
