A company is implementing a wireless solution in a high-density environment. Which of the following 802.11 standards is used when a company is concerned about device saturation and converage?
802.11ax, also known as Wi-Fi 6, is designed for high-density environments and improves device saturation and coverage compared to previous standards.
802.11ac: While it offers high throughput, it is not optimized for high-density environments as effectively as 802.11ax.
802.11ax (Wi-Fi 6): Introduces features like OFDMA, MU-MIMO, and BSS Coloring, which enhance performance in crowded environments, reduce latency, and increase the number of devices that can be connected simultaneously.
802.11g and 802.11n: Older standards that do not offer the same level of efficiency or support for high device density as 802.11ax.
Network Reference:
CompTIA Network+ N10-007 Official Certification Guide: Covers the 802.11 standards and their capabilities.
Cisco Networking Academy: Provides training on Wi-Fi technologies and best practices for high-density deployments.
Which of the following is the most likely reason an insurance brokerage would enforce VPN usage?
The most likely reason an insurance brokerage would enforce VPN usage is to encrypt sensitive data in transit. VPNs (Virtual Private Networks) create a secure tunnel between the user's device and the corporate network, ensuring that data is encrypted and protected from interception.
Encryption: VPNs encrypt data, preventing unauthorized access and ensuring data privacy during transmission over public or unsecured networks.
Data Protection: Essential for industries handling sensitive information, such as insurance brokerages, to protect customer data and comply with regulatory requirements.
Security: Enhances overall network security by providing secure remote access for employees.
Network Reference:
CompTIA Network+ N10-007 Official Certification Guide: Discusses the role of VPNs in securing data in transit.
Cisco Networking Academy: Provides training on VPN technologies and their importance in data security.
Network+ Certification All-in-One Exam Guide: Explains VPN usage and its benefits in protecting sensitive information.
A network administrator for a small office is adding a passive IDS to its network switch for the purpose of inspecting network traffic. Which of the following should the administrator use?
Port mirroring, also known as SPAN (Switched Port Analyzer), is used to send a copy of network packets seen on one switch port (or an entire VLAN) to another port where the IDS is connected. This allows the IDS to passively inspect network traffic without interfering with the actual traffic flow. Port mirroring is an essential feature for implementing IDS in a network for traffic analysis and security monitoring. Reference: CompTIA Network+ study materials.
A company's marketing team created a new application and would like to create a DNS record for newapplication.comptia.org that always resolves to the same address as www.comptia.org. Which of the following records should the administrator use?
The DNS section of the CompTIA Network+ materials describes the use of CNAME records for creating domain aliases.
An organization has a security requirement that all network connections can be traced back to a user. A network administrator needs to identify a solution to implement on the wireless network. Which of the following is the best solution?
Enterprise authentication (such as WPA2-Enterprise) utilizes unique credentials for each user, typically integrating with an authentication server like RADIUS. This allows for tracking and logging user activity, ensuring that all connections can be traced back to individual users. PSKs (Pre-Shared Keys) are shared among users and do not provide individual accountability. Captive portals can identify users but are less secure than enterprise authentication, and Wired Equivalent Privacy (WEP) is outdated and not recommended for security purposes.
CompTIA Network+ materials highlight enterprise authentication methods as the preferred solution for secure and accountable wireless network access.
