CompTIA N10-008 Online Questions & Answers

• Question 751:

  A technician is installing a high-density wireless network and wants to use an available frequency that supports the maximum number of channels to reduce interference. Which of the following standard 802.11 frequency ranges should the technician look for while reviewing WAP specifications?

  A. 2.4GHz
  B. 5GHz
  C. 6GHz
  D. 900MHz
  B. 5GHz

  ---

  Explanation/Reference:

  5GHz is the frequency range that supports the maximum number of channels and reduces interference in a high-density wireless network. The 802.11 standard for this range offers more non-overlapping channels, which reduces the likelihood of interference with other devices and improves overall network performance.

• Question 752:

  A customer wants to segregate the traffic between guests on a hypervisor. Which of the following does a technician need to configure to meet the requirement?

  A. Virtual switches
  B. OSPF routing
  C. Load balancers
  D. NIC teaming
  E. Fibre Channel
  A. Virtual switches

  ---

  Explanation/Reference:

  A virtual switch is a software-based switch that connects virtual machines on a hypervisor. A virtual switch can create and manage VLANs, which are logical segments of a network that isolate traffic between different groups of devices. A

  customer can use virtual switches to segregate the traffic between guests on a hypervisor by creating a separate VLAN for each guest and assigning it to a virtual switch port.

• Question 753:

  A network is experiencing extreme latency when accessing a particular website. Which of the following commands will BEST help identify the issue?

  A. ipconfig
  B. netstat
  C. tracert
  D. ping
  C. tracert

  ---

  Explanation/Reference:

  "tracert" command is short for "traceroute," the CLI command which determines the route a packet takes to its destination. Knowing which networks a packet travels through is essential in identifying latency when visiting a website.

• Question 754:

  Which of the following is an example of on-demand scalable hardware that is typically housed in the vendor's data center?

  A. DaaS
  B. IaaS
  C. PaaS
  D. SaaS
  B. IaaS

• Question 755:

  Which of the following protocols would allow a secure connection to a Linux-based system?

  A. SMB
  B. FTP
  C. RDP
  D. SSH
  D. SSH

• Question 756:

  A network administrator is deploying a new switch and wants to make sure that the default priority value was set for a spanning tree. Which of the following values would the network administrator expect to see?

  A. 4096
  B. 8192
  C. 32768
  D. 36684
  C. 32768

  ---

  Explanation/Reference:

  The default priority value for spanning tree is 32768, regardless of the STP version (legacy STP, RSTP, MSTP, Per-VLAN STP, Per-VLAN RSTP). This value can be modified by the network administrator to influence the root bridge election. The priority value must be set in increments of 4096, which is the minimum unit of change for the priority value.

• Question 757:

  A workstation on the network is configured as follows. A user reports that they are unable to print to a device located on a different subnet. Which of the following is the MOST likely problem? IP address: 172.16.204.12 Subnet Mask:

  255.255.0.0 Default Gateway: 172.15.204.254 DNS address: 172.16.204.1 Broadcast address: 172.16.255.255

  A. DNS address
  B. Subnet mask
  C. Default gateway
  D. Broadcast address
  E. IP address
  C. Default gateway

• Question 758:

  Which of the following would an organization MOST likely have employees sign before granting access to confidential data?

  A. An AUP
  B. A BYOD policy
  C. An NDA
  D. A PUA

• Question 759:

  Which of the following architectures is used for FTP?

  A. Client-server
  B. Service-oriented
  C. Connection-oriented
  D. Data-centric
  A. Client-server

  ---

  Explanation/Reference:

  FTP (File Transfer Protocol) is a client-server based protocol, meaning that the two computers involved communicate with each other in a request-response pattern. The client sends a request to the server and the server responds with the requested data. This type of architecture is known as client-server, and it is used for many different types of applications, including FTP. Other architectures, such as service-oriented, connection- oriented, and data-centric, are not used for FTP.

• Question 760:

  A company has multiple site-to-site VPN connections using a pre-shared key. The Chief Information Security Officer (CISO) is concerned about the long-term security of the tunnels and has asked the network technicians to develop a plan to ensure the best security of the tunnels. Which of the following should the network technicians implement?

  A. Purchase dedicated MPLS circuits between each of the sites.
  B. Request a change of IP addresses from the ISP semiannually.
  C. Perform annual key rotations on the site-to-site VPNs.
  D. Terminate tunnels when they are not actively being used.
  C. Perform annual key rotations on the site-to-site VPNs.
