NEW QUESTION # 36
A company deployed new applications in the cloud and configured a site-to-site VPN to connect the internal data center with the cloud. The IT team wants the internal servers to connect to those applications without using public IP addresses. Which of the following is the best solution?

  • A. Configure proxy service in the site-to-site VPN to allow internal servers to access applications through the proxy.
  • B. Create a DNS server in the cloud. Configure the DNS server in the customer data center to forward DNS requests for cloud resources to the cloud DNS server.
  • C. Configure a NAT server on the cloud to allow internal servers to connect to the applications through the NAT server.
  • D. Register applications on the cloud with a public DNS server and configure internal servers to connect to them using their public DNS names.

Answer: B

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To allow private IP-based communication between internal servers and cloud applications over asite-to-site VPN, private DNS resolution is necessary. The internal DNS server can be configured to forward specific DNS queries (for cloud-based applications) to a DNS server located in the cloud. This ensures applications can be resolved to private IPs, not public ones.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Hybrid Networking and DNS Integration":
"To support name resolution over hybrid connections like site-to-site VPN, enterprises should configure conditional forwarding to cloud-based DNS servers. This allows internal devices to resolve private IP addresses for cloud-based resources." Other options:
* B. NAT introduces complexity and may hide source IPs, which is not required in this case.
* C. Public DNS names map to public IPs, violating the requirement.
* D. A proxy is not needed if direct private IP-based access is available via VPN.

NEW QUESTION # 41
A network architect is choosing design options for a new SD-WAN installation that has the following requirements:
* All network traffic from the cloud must pass through inspection devices in a dedicated data center.
* Ensure redundancy.
* Centralize egress traffic.
Which of the following network topologies best meets these requirements?

  • A. Star
  • B. Partial mesh
  • C. Point-to-point
  • D. Hub-and-spoke

Answer: D

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Hub-and-Spoke topology is ideal for SD-WAN environments where traffic from branch offices or cloud workloads must route through a central location (the hub) for inspection, monitoring, or security enforcement.
This structure centralizes egress and allows for redundant spoke paths via the hub. It also simplifies control and enforces compliance policies.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "SD-WAN Topologies and Cloud Egress Strategies":
"In a hub-and-spoke topology, spokes (remote offices or cloud nodes) connect through a central hub, allowing for centralized egress, traffic inspection, and simplified routing." Other options:
* A. Point-to-point doesn't scale and lacks centralized control.
* C. Star topology is similar to hub-and-spoke but is more rigid and less suited for SD-WAN scalability.
* D. Partial mesh allows direct spoke-to-spoke communication, bypassing centralized inspection.


NEW QUESTION # 42
End users are getting certificate errors and are unable to connect to an application deployed in a cloud. The application requires HTTPS connection. A network solution architect finds that a firewall is deployed between end users and the application in the cloud. Which of the following is the root cause of the issue?

  • A. The firewall has an expired certificate while SSL/HTTPS inspection is enabled.
  • B. The firewall on the application server has port 443 blocked.
  • C. The end users do not have certificates on their laptops.
  • D. The firewall has port 443 blocked while SSL/HTTPS inspection is enabled.

Answer: A

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
When SSL/HTTPS inspection is enabled on a firewall, it intercepts and decrypts HTTPS traffic. This requires the firewall to present its own trusted certificate to the client device. If that certificate is expired, the client browser will display a certificate error and block access to the application. This is a common misconfiguration that breaks HTTPS communication.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "TLS/SSL Inspection and Certificate Management":
"SSL inspection appliances must have valid certificates installed. Expired or untrusted certificates will result in browsers rejecting the HTTPS session and displaying errors to users." Other options:
* A. Would prevent connection, but not result in certificate errors.
* B. Blocked port 443 would prevent any connection, not cause cert errors.
* C. Client-side certificates are not required unless mutual TLS is configured, which is not stated here.


NEW QUESTION # 43
A network architect is designing a solution to place network core equipment in a rack inside a data center.
This equipment is crucial to the enterprise and must be as secure as possible to minimize the chance that anyone could connect directly to the network core. The current security setup is:
In a locked building that requires sign in with a guard and identification check.
In a locked data center accessible by a proximity badge and fingerprint scanner.
In a locked cabinet that requires the security guard to call the Chief Information Security Officer (CISO) to get permission to provide the key.
Which of the following additional measures should the architect recommend to make this equipment more secure?

  • A. Make all engineers with access to the data center sign a statement of work.
  • B. Have the CISO accompany any network engineer that needs to do work in this cabinet.
  • C. Require anyone entering the data center for any reason to undergo a background check.
  • D. Set up a video surveillance system that has cameras focused on the cabinet.

Answer: D

Explanation:
Recording and monitoring all activity at the cabinet greatly strengthens security by providing a real-time deterrent, an audit trail of who accessed it and when, and forensic evidence if an incident ever occurs.


NEW QUESTION # 44
A company provides an API that runs on the public cloud for its customers. A fixed number of VMs host the APIs. During peak hours, the company notices a spike in usage that results in network communication speeds slowing down for all customers. The management team has decided that access for all customers should be fair and accessible at all times. Which of the following is themostcost-effective way to address this issue?

  • A. Use an allow list for customers using APIs.
  • B. Enable throttling on APIs.
  • C. Increase the MTU on the VMs.
  • D. Increase the number of VMs running APIs.

Answer: B

Explanation:
Implementing request throttling (rate limiting) lets you cap how many requests each customer can make per time unit. This ensures no single user can saturate the API servers, providing fair access across all customers without the recurring costs of adding more VMs.


NEW QUESTION # 45
An architect needs to deploy a new payroll application on a cloud host. End users' access to the application will be based on the end users' role. In addition, the host must be deployed on the 192.168.77.32/30 subnet.
Which of the following Zero Trust elements are being implemented in this design? (Choose two.)

  • A. MFA
  • B. Least privilege
  • C. Device trust
  • D. WAF
  • E. Microsegmentation
  • F. CASB

Answer: B,E

Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A: Least privilege - This Zero Trust principle ensures users can only access the resources necessary for their job roles. Role-based access control (RBAC), as mentioned in the scenario, is a textbook implementation of least privilege.
C: Microsegmentation - Deploying the application in a small subnet (192.168.77.32/30 provides only 2 usable host IPs) limits lateral movement and isolates the host at a network level. This is a key characteristic of microsegmentation, where resources are placed in small, tightly controlled network segments.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Zero Trust Security Architecture":
"Least privilege enforces access permissions based on job responsibilities."
"Microsegmentation applies granular isolation policies between resources to reduce the attack surface and lateral movement." Other options:
* B. Device trust involves assessing device posture and compliance before granting access.
* D. CASB (Cloud Access Security Broker) governs cloud access, not access control or subnetting.
* E. WAF protects web applications but is not a Zero Trust element directly related to access control.
* F. MFA supports identity verification but is not directly evidenced in the scenario.


NEW QUESTION # 46
A network engineer is setting up guest access on a Wi-Fi network. After a recent network analysis, the engineer discovered that a user could access the guest network and attack the corporate network, since the networks share the same VLAN. Which of the following should the engineer do to prevent an attack like this one from happening?

  • A. Configure Layer 2 client isolation for the wireless network.
  • B. Set up a strong password on the guest wireless network.
  • C. Set up a MAC filtering rule and add the MAC addresses of all corporate devices to the allow list.
  • D. Set up a captive portal so all guest users have to register before gaining access to the wireless network.

Answer: A

Explanation:
By enabling client isolation at Layer 2, guest clients can still reach the Internet but cannot directly communicate with any other device on that VLAN, including your corporate endpoints, stopping lateral attacks without needing MAC whitelists or overly complex captive-portal setups.
