CompTIA N10-008 Online Questions & Answers

• Question 721:

  A user reports that a new VoIP phone works properly, but the computer that is connected to the phone cannot access any network resources. Which of the following MOST likely needs to be configured correctly to provide network connectivity to the computer?

  A. Port duplex settings
  B. Port aggregation
  C. ARP settings
  D. VLAN tags
  E. MDIX settings
  D. VLAN tags

  ---

  Explanation/Reference:

  VLAN (virtual LAN) tags are used to identify packets as belonging to a particular VLAN. VLANs are used to segment a network into logical sub-networks, and each VLAN is assigned a unique VLAN tag. If the VLAN tag is not configured correctly, the computer may not be able to access network resources.

• Question 722:

  A senior administrator has been directed to incorporate AAA services within a domain environment for regulatory compliance purposes. Which of the following standards will enable the use of an AAA server in a domain environment?

  A. 802.1Q
  B. 802.1X
  C. 802.3bt
  D. 802.11h
  B. 802.1X

  ---

  Explanation/Reference:

  802.1X is a standard that enables the use of an AAA server in a domain environment by providing port-based network access control. 802.1X authenticates users or devices before granting them access to the network resources, and can also authorize them based on their roles or policies. 802.1X can work with different AAA protocols, such as RADIUS or TACACS+, to communicate with the AAA server.

• Question 723:

  Which of the following is the MOST appropriate use case for the deployment of a clientless VPN?

  A. Secure web access to internal corporate resources.
  B. Upgrade security via the use of an NFV technology.
  C. Grant out-of-band access for partners accessing corporate resources.
  D. Increase VPN availability by using a SDWAN technology.
  A. Secure web access to internal corporate resources.

  ---

  Explanation/Reference:

  Clientless VPNs are typically used for providing secure remote access to internal resources without requiring the installation of a dedicated client software on the user's device. They are well-suited for scenarios where users need to access internal resources, such as web applications, files, or services, securely from remote locations using standard web browsers.

• Question 724:

  Which of the following is the first step a network administrator should take in the troubleshooting methodology?

  A. Establish a plan of action.
  B. Document findings and outcomes.
  C. Test the theory to determine cause.
  D. Identify the problem.
  D. Identify the problem.

  ---

  Explanation/Reference:

  According to the network troubleshooting methodology, the first step a network administrator should take is to identify the problem. This involves gathering information from the users, the network devices, and the symptoms of the issue.

  Identifying the problem helps to narrow down the scope and the possible causes of the network issue.

  A. Mesh
  B. Star
  C. Bus
  D. Ring
  A. Mesh

  ---

  Explanation/Reference:

  Mesh topology requires the MOST connections when designing a network as it uses a point-to-point connection between every pair of devices in the network, resulting in a large number of connections.

• Question 727:

  Which of the following refers to a weakness in a mechanism or technical process?

  A. Vulnerability
  B. Risk
  C. Exploit
  D. Threat
