CompTIA Network+ N10-009 Information

The CompTIA Network+ N10-009 certification exam is a key credential for IT professionals specializing in network technologies and infrastructure. This exam assesses a candidate's ability to design, configure, manage, and troubleshoot wired and wireless network devices. Unlike more specialized certifications, the Network+ offers a broad foundation, making it ideal for early-career network technicians and administrators. It covers emerging technologies like cloud computing and virtualization, while also emphasizing traditional networking concepts and practices. By passing the N10-009 exam, candidates demonstrate their expertise in these areas, proving their readiness for roles such as network administrator, network field technician, and help desk technician.

The exam's content is divided into several key areas. Network architecture forms a significant part, where candidates must understand the design and implementation of functional networks, including network components and their roles in network services. Network security is also crucial, requiring knowledge of security concepts and protocols, as well as the skills to implement security features on network devices. The exam also tests on network operations and troubleshooting, focusing on monitoring tools, network performance optimization, and problem-solving techniques. Moreover, it includes newer areas like cloud computing and virtualization, reflecting the evolving nature of network technology. This wide-ranging scope ensures that professionals holding the Network+ certification are equipped to support and manage modern network environments effectively.

Question 1 of 15

Tabletop exercises involve the physical deployment of recovery procedures and actual system failover to simulate a data recovery process.

  • False

  • True

Question 2 of 15

What principle does role-based access control (RBAC) primarily employ to manage user permissions and access within a network?

  • Implementing multifactor authentication for access verification

  • Granting every user individual permissions based on personal requests

  • Using a single master password for access control

  • Assigning permissions based on the specific roles within an organization

Question 3 of 15

What is the primary function of a VLAN?

  • To encrypt data traffic on a network.

  • To segment a network into different broadcast domains.

  • To increase the speed of network connections.

  • To physically connect different network devices.

Question 4 of 15

Which type of interface counter increase typically suggests data corruption issues during transmission?

  • Giants are frequently observed

  • Runts are increasing

  • Checksum errors are increasing

  • Collision rates are frequently high

Question 5 of 15

What is the primary role of an operating system in the management of network devices?

  • It is responsible for generating the internet protocol (IP) addresses allocated to each network device.

  • It physically manages network connections and cable setups.

  • It provides the fundamental software platform on which applications run and interact with the hardware.

  • It exclusively manages the security protocols for network devices.

Question 6 of 15

An enterprise network is experiencing poor VoIP call quality, and complaints are coming from multiple departments. No recent changes have been reported. Which approach would be most effective for initially investigating this network-wide issue?

  • Use a top-to-bottom OSI model approach to check each layer.

  • Use a Wi-Fi analyzer solely on the wireless networks.

  • Conduct an extensive audit of recent network changes despite reports.

  • Immediately replace VoIP hardware like phones and PBX systems.

Question 7 of 15

A network administrator at a large organization notices a rapid increase in the number of devices needing network access, pushing the network's capacity limits. Which solution best addresses this scenario to prevent running out of network addresses?

  • Implementing IPv6 addressing to expand the network address space

  • Assigning only private address ranges within the network

  • Using Network Address Translation

  • Applying more stringent subnetting strategies

Question 8 of 15

A telecommunications provider wants to upgrade its core network infrastructure to improve scalability and reduce operational expenses associated with physical network devices. The solution should enable dynamic management of network services such as VPNs and intrusion prevention systems. Which technology would best fulfill these requirements?

  • Software-defined Networking (SDN)

  • Network Functions Virtualization (NFV)

  • Multiprotocol Label Switching (MPLS)

  • Internet Protocol Security (IPSec)

Question 9 of 15

A network administrator notices that a switch port, which connects to a server, is no longer active and upon checking, finds that the port has been put into an 'error disabled' state. What is the MOST likely cause for this state?

  • The switch experienced a temperature anomaly exceeding operational thresholds.

  • The port security settings have been violated, such as exceeding the maximum number of allowed MAC addresses.

  • The DHCP server has run out of IP addresses to assign to clients.

  • There was an incorrect cable type used between the server and the switch.

Question 10 of 15

Port mirroring sends copies of network packets from one port on a switch to a specific destination port for analysis.

  • True

  • False

Question 11 of 15

A company plans to extend its Wi-Fi coverage to ensure seamless connectivity across its large, multi-floor office building without installing additional cabling. They are considering using a mesh network. Which of the following benefits is a primary reason for choosing a mesh network in this scenario?

  • It inherently provides better bandwidth utilization.

  • It ensures fiber optic or ethernet cabling is redundant and fail-safe

  • It significantly increases the amount of broadcast traffic.

  • It allows extensive coverage with minimal physical infrastructure.

Question 12 of 15

Which type of zone is responsible for mapping IP addresses back to their associated domain names?

  • Forward zone

  • Redirection zone

  • Security zone

  • Reverse zone

Question 13 of 15

In a medium-sized enterprise, the network administrator is configuring a new office network. The administrator needs to ensure that traffic intended for the internet is properly routed through the gateway. What is the primary function of the deployed router in this scenario?

  • To balance the load across multiple internet links.

  • To route data packets between different networks, including to the internet gateway.

  • To act as a DHCP server and assign IP addresses.

  • To perform deep packet inspection and content filtering.

Question 14 of 15

An organization has implemented SD-WAN to enhance network performance among its branch offices. The network administrator wants to ensure that specific types of network traffic are identified and given priority over others to meet performance requirements. Which SD-WAN feature enables this capability?

  • Traditional static routing

  • Application-aware routing

  • Link aggregation

  • Firewall filtering

Question 15 of 15

In the context of Infrastructure as Code (IaC), how does the application of configuration drift practices affect network upgrade processes?

  • It prevents the need for manual intervention in network troubleshooting post-upgrade.

  • It reduces the cost associated with physical components in network upgrades.

  • It helps identify unauthorized changes and ensures that the network configuration adheres to defined compliance standards during upgrades.
