Holding a CompTIA CloudNetX Certification Exam CNX-001 Certification in a certain field definitely shows that one have a good command of the CNX-001 knowledge and professional skills in the related field. However, it is universally accepted that the majority of the candidates for the CompTIA CloudNetX Certification Exam exam are those who do not have enough spare time and are not able to study in the most efficient way.
NEW QUESTION # 34
A company hosts a cloud-based e-commerce application and only wants the application accessed from certain locations. The network team configures a cloud firewall with WAF enabled, but users can access the application globally. Which of the following should the network team do?
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A Web Application Firewall (WAF) is primarily used for inspecting HTTP/HTTPS requests and filtering out malicious traffic, such as SQL injection or cross-site scripting (XSS) attacks. However, WAFs do not restrict access based on geographical location by default.
To control access to the cloud-hosted application based on geographical location, the correct measure is to implement geo-restriction (geo-blocking). This technique limits access to cloud-based resources by using the source IP's geographical origin. Geo-restriction is typically enforced at the cloud firewall or load balancer level.
Relevant Extract from CompTIA CloudNetX CNX-001 Official Objectives:
"Cloud access control policies can enforce geo-restriction settings, ensuring applications and services are only accessible from authorized geographic regions." Also found under "Security Controls in Cloud Deployments" section:
"Geo-restriction uses IP geolocation data to restrict access to services based on geographic criteria, supporting compliance and security requirements."
NEW QUESTION # 35
An administrator needs to add a device to the allow list in order to bypass user authentication of an AAA system. The administrator uses MAC filtering and needs to discover the device's MAC address to accomplish this task. The device receives an IP address from DHCP, but the IP address changes daily. Which of the following commands should the administrator run on the device to locate its MAC address?
Answer: B
Explanation:
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.
NEW QUESTION # 36
A cloud network engineer needs to enable network flow analysis in the VPC so headers and payload of captured data can be inspected. Which of the following should the engineer use for this task?
Answer: A
Explanation:
VPC Traffic Mirroring lets you capture copies of inbound and outbound network traffic, full packet headers and payload, and send them to appliances or analysis tools for deep inspection, which goes beyond the metadata provided by standard flow logs.
NEW QUESTION # 37
Security policy states that all inbound traffic to the environment needs to be restricted, but all external outbound traffic is allowed within the hybrid cloud environment. A new application server was recently set up in the cloud. Which of the following would most likely need to be configured so that the server has the appropriate access set up? (Choose two.)
Answer: D,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
To meet the requirement of restricting inbound traffic and allowing outbound traffic, two components are most appropriate:
D: Firewall - A firewall enforces ingress and egress traffic policies. It can be configured to deny all inbound traffic by default and allow all outbound traffic, meeting the security policy requirement.
E: Network Security Group (NSG) - In cloud environments such as Azure, NSGs serve as virtual firewalls at the subnet or interface level. NSGs allow you to define rules that block or allow inbound and outbound traffic, and they are the preferred method for enforcing network access rules for cloud resources.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Cloud Network Security Configuration":
"Network security groups and firewalls are key to enforcing inbound and outbound traffic restrictions in hybrid and public cloud environments."
"NSGs are used to define network access control policies for cloud resources at the subnet or NIC level." Other options:
* A. Application gateway controls HTTP/S traffic at Layer 7 but does not manage full access policy.
* B. IPS detects/prevents malicious behavior but is not primarily used for general traffic restriction.
* C. Port security restricts MAC addresses on switch ports, applicable in LANs, not cloud.
* F. A screened subnet (DMZ) can provide additional isolation but is not required for basic traffic control.
NEW QUESTION # 38
A network architect is designing a new network for a rural hospital system. Given the following requirements:
* Highly available
* Consistent data transmission
* Resilient to simultaneous failures
Which of the following topologies should the architect use?
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A mesh topology provides multiple redundant paths between nodes. It offers the highest availability and fault tolerance by allowing communication to continue even if one or more links or nodes fail. This is especially important in rural healthcare systems where reliability and access to critical services are paramount.
Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide - under "Network Topologies and Redundancy Models":
"Mesh topologies provide optimal fault tolerance and support consistent data transmission through redundant links, ideal for mission-critical systems." Other options:
* A. Collapsed core is cost-efficient but not fully redundant.
* B. Hub-and-spoke introduces a single point of failure at the hub.
* D. Star also relies on a central node and is not fault tolerant.
