CompTIA CompTIA Mobility+ N10-005 Questions & Answers

• Question 571:

  A technician has been given the task to install a wireless network in a user's home.

  Which of the following should the technician consider when implementing the network? (Select TWO).

  A. That there is strong encryption enabled and configured on the access point.

  B. The user's home network has a correctly completed WHOIS entry.

  C. The access point is broadcasting the SSID based upon manufacturer's standards.

  D. There are no conflicts of channels in use by neighboring wireless networks.

  E. There are redundant internal DNS names set in the access point's settings.

  F. That the access point's MAC address is properly set in its configuration settings.

  Correct Answer: AD

  Strong encryption is required to keep the user's internet safe and secure so as to avoid misuse of the internet connection and to ensure that channel conflicts are not there so that the signals do not compete with each other and user start to face intermittent connection.

• Question 572:

  Some employees are unable to maintain a wireless network connection. The network's wireless infrastructure is comprised of three different buildings with the configurations listed below. Wireless network in Building A and C is used exclusively for internal employees and Building B is used for visitors and requires no additional configuration on their devices.

  Which of the following settings would need to be modified to provide the BEST wireless experience for all employees as they move between buildings?

  Building A Building B Building C Channel: 1 Channel: 6 Channel: 11 Encryption: WPA2 Encryption: Open Encryption: WPA2 SSID. Corp SSID. Guest SSID. Sales

  A. Change Channel in Building B to 7

  B. Change Encryption in Building B to match A and C

  C. Change Channel in Building C to 1

  D. Change SSID in Building C to match Building A

  Correct Answer: D

  The configuration difference between users in building A and C is that they have same encryption however the SSID is different so the user has to manually authenticate and connect to the network whenever he will move between buildings. If the SSID's are same then he will not have to authenticate himself again and he will get automatic connectivity.

• Question 573:

  Some visitors are unable to access the wireless network. The network's wireless infrastructure is comprised of three different buildings with the configurations listed below. Wireless network in Building A and C is used exclusively for internal employees and Building B is used for visitors and requires no additional configuration on their devices.

  Which of the following settings would need to be modified to provide wireless access to all visitors?

  Building A Building B Building C Channel: 2 Channel: 6 Channel: 11 Encryption: WPA2 Encryption: WPA2 Encryption: WPA2

  A. Encryption set to Open in all Buildings

  B. Encryption set to Open in Building B

  C. Encryption set to WEP in Building B

  D. Channel set to 11 in Building B

  Correct Answer: B

  Because the building B is in the middle, the wireless access router will have reachability to the building A and C. Now, the only thing that we need to do is to open the Wireless access on B for the guest users for the WAP in B so that the users coming to building A and C can get access to internet using the open connection.

• Question 574:

  A company has recently allowed its employees to telecommute two days a week. The employees MUST have a minimum of 1Mbps non-shared connection to the Internet. Which of the following MUST the employees have at their home in order to connect to the Internet?

  A. ISDN

  B. Cable modem

  C. DSL

  D. Dial-up networking

  Correct Answer: C

  Digital subscriber line (DSL, originally digital subscriber loop) is a family of technologies that provide Internet access by transmitting digital data over the wires of a local telephone network.

• Question 575:

  After a network technician has added a new workstation and cabling to the network, users report the network is very slow. The activity lights on all switches are blinking rapidly, showing large amounts of traffic. Which of the following is the BEST explanation for the traffic?

  A. The new user is downloading large files.

  B. The router failed, flooding the network with beacons.

  C. The new user's IP address is a duplicate.

  D. A switching loop was created.

  Correct Answer: D

  Switching loop or Bridge loop occurs in computer networks when there is more than one Layer 2 (OSI model) path between two endpoints (e.g. multiple connections between two network switches or two ports on the same switch connected to each other). The loop creates broadcast radiation as broadcasts and multicasts are forwarded by switches out every port, the switch or switches will repeatedly rebroadcast the broadcast messages flooding the network.

• Question 576:

  Which of the following performance benefits would multiple domain controllers BEST provide?

  A. Fault tolerance

  B. Caching engine

  C. Proxy server

  D. Quality of service

  Correct Answer: A

  Fault-tolerant design is a design that enables a system to continue its intended operation, possibly at a reduced level, rather than failing completely, when some part of the system fails. The term is most commonly used to describe computer-based systems designed to continue more or less fully operational with, perhaps, a reduction in throughput or an increase in response time in the event of some partial failure

• Question 577:

  After a new user moves furniture into a cubicle, the computer does not connect to the network any longer. Which of the following would be the MOST likely reason? (Select TWO).

  A. Bad Ethernet switch port

  B. TX/RX reversed

  C. Bad connectors

  D. Bad patch cable

  E. Mismatched MTU

  Correct Answer: CD

  It could be problem with the bad connector because the user just moved furniture to the cubicle and it is quite possible that the movement of the furniture has created problem by disrupting the cabling and connections. These two are the important things which can be broken down whenever there is a physical movement.

• Question 578:

  Ann, a technician, is installing network cables for an office building. Some of the cables are not showing active on the switch even when moved to different ports. Which of the following is MOST likely the cause?

  A. Port speed mismatch

  B. Faulty F-connectors

  C. Bad wiring

  D. Bad switch

  Correct Answer: C

  Bad wiring refers to the state when you do not follow a pattern and everything seems messed up and you are not able to figure out the cause.

• Question 579:

  A network administrator suspects a broadcast storm is causing performance issues on the network. Which of the following would be used to verify this situation?

  A. Environmental monitor

  B. Multimeter

  C. Toner probe

  D. Protocol analyzer

  Correct Answer: D

  A "Protocol analyzer" is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.

• Question 580:

  Which of the following is a terminal emulator used to manage a network device?

  A. VPN

  B. IDS

  C. PuTTY

  D. IPS

  Correct Answer: C

  PuTTY is a free and open-source terminal emulator, serial console and network file transfer application. It supports several network protocols, including SCP, SSH, Telnet and rlogin.
