• Question 731:

  A SOHO with ten Wi-Fi equipped laptops needs a new network installed. Which of the following items would be used to setup the office using a new DSL line? (Select TWO).

  A. Router

  B. Wi-Fi Access point

  C. Cable modem

  D. Ten WiMAX adapters

  E. Ten CAT6 patch cables

  Correct Answer: AB

• Question 732:

  A network technician is hired to review all the devices within a network and make recommendations to improve network efficiency. Which of the following should the technician do FIRST before reviewing and making any recommendations?

  A. Capture a network baseline

  B. Perform an environmental review.

  C. Read the network logs

  D. Run a bandwidth test

  Correct Answer: A

  Before making any recommendations, a network technician should first capture a network baseline, which is a snapshot of the current performance of the network. This will give the technician a baseline to compare against after any changes are made. According to the CompTIA Network+ Study Manual, the technician should "capture the state of the network before making any changes and then compare the performance after the changes have been made. This will provide an accurate baseline to compare the performance of the network before and after the changes have been made."

• Question 733:

  A national cable company providing TV, telephone, and Internet service to home users over its IP network, has been tracking a large increase of network bandwidth due to P2P file sharing. Which of the following should the company deploy to ensure excellent TV and telephone service?

  A. QoS

  B. Load balancing

  C. High availability

  D. Fiber optics

  Correct Answer: A

• Question 734:

  Which of the following BEST describes the difference between layer 2 switching and layer 2 routing?

  A. Switching moves packets between hosts on different subnets, and routing moves packets between hosts on the same subnet.

  B. Routing moves packets between hosts on different subnets, and switching moves packets between hosts on the same subnet.

  C. Both routing and switching move packets between hosts on the same subnet, but routing does so at a faster pace.

  D. Both routing and switching move packets between hosts on different subnets, but switching does so at a faster pace.

  Correct Answer: B

• Question 735:

  Which of the following describes the ability of a corporate IT department to expand its cloud-hosted VM environment with minimal effort?

  A. Scalability

  B. Load balancing

  C. Multitenancy

  D. Geo-redundancy

  Correct Answer: A

  Scalability is the ability of a corporate IT department to expand its cloud- hosted virtual machine (VM) environment with minimal effort. This allows IT departments to quickly and easily scale up their cloud environment to meet increased demand. Scalability also allows for the efficient use of resources, as IT departments can quickly and easily scale up or down as needed.

• Question 736:

  B. Crimper

  C. Cable tester

  D. Punch down tool

  Correct Answer: C

  A. The arp table of the new customer's router.

  B. The route table of the next-hop router.

  C. The route table of the new customer's router.

  D. The arp table of a network user.

  Correct Answer: C

• Question 738:

  Lisa, a technician, is tasked to monitor various analog POTS lines for voice activity. Which of the following hardware tools would be used?

  A. Butt set

  B. Toner probe

  C. Wire mapper

  D. Cable certifier

  Correct Answer: A

• Question 739:

  An organization with one core and five distribution switches is transitioning from a star to a full-mesh topology. Which of the following is the number of additional network connections needed?

  A. 5

  B. 7

  C. 10

  D. 15

  Correct Answer: C

  10 additional network connections are needed to transition from a star to a full-mesh topology. A star topology is a network topology where each device is connected to a central device, such as a switch or a hub. A full-mesh topology is a network topology where each device is directly connected to every other device. The number of connections needed for a full-mesh topology can be calculated by the formula n(n-1)/2, where n is the number of devices. In this case, there are six devices (one core and five distribution switches), so the number of connections needed for a full-mesh topology is 6(6-1)/2 = 15. Since there are already five connections in the star topology (one from each distribution switch to the core switch), the number of additional connections needed is 15 - 5 = 10.

• Question 740:

  A local firm has hired a consulting company to clean up its IT infrastructure. The consulting company notices remote printing is accomplished by port forwarding via publicly accessible IPs through the firm's firewall. Which of the following would be the MOST appropriate way to enable secure remote printing?

  A. SSH

  B. VPN

  C. Telnet

  D. SSL

  Correct Answer: B

  VPN (Virtual Private Network) is the most appropriate way to enable secure remote printing. VPN is a technology that creates a secure and encrypted tunnel over a public network such as the Internet. It allows remote users or sites to access a private network as if they were directly connected to it. VPN can be used for various purposes such as accessing corporate resources, bypassing geo-restrictions, or enhancing privacy and security. VPN can also be used for remote printing by allowing users to connect to a printer on the private network and send print jobs securely over the VPN tunnel.
