CompTIA N10-006 Online Questions & Answers

• Question 161:

  A host has been assigned the address 169.254.0.1. This is an example of which of the following address types?

  A. APIPA
  B. MAC
  C. Static
  D. Public
  A. APIPA

  ---

  APIPA stands for Automatic Private IP Addressing and is a feature of Windows operating systems. When a client computer is configured to use automatic addressing (DHCP), APIPA assigns a class B IP address from 169.254.0.0 to 169.254.255.255 to the client when a DHCP server is unavailable. When a client computer configured to use DHCP boots up, it first looks for a DHCP server to provide the client with IP address and subnet mask. If the client is unable to contact a DHCP server, it uses APIPA to automatically configure itself with an IP address from a range that has been reserved especially for Microsoft. The client also configures itself with a default class Bsubnet mask of 255.255.0.0. The client will use the self-configured IP address until a DHCP server becomes available.

• Question 162:

  After a company rolls out software updates, Ann, a lab researcher, is no longer able to use lab equipment connected to her PC. The technician contacts the vendor and determines there is an incompatibility with the latest IO drivers. Which of the following should the technician perform so that Ann can get back to work as quickly as possible?

  A. Reformat and install the compatible drivers.
  B. Reset Ann's equipment configuration from a backup.
  C. Downgrade the PC to a working patch level.
  D. Restore Ann's PC to the last known good configuration.
  E. Roll back the drivers to the previous version.
  E. Roll back the drivers to the previous version.

  ---

  By rolling back the drivers Ann would be able touse her lab equipment again. To roll back a driver in Windows means to return the driver to the version that was last installed for the device. Rolling back a driver is an easy way to return a driver to a working version when a driver update fails to fix aproblem or maybe even causes a new problem. Think of rolling back a driver as a quick and easy way to uninstall the latest driver and then reinstall the previous one, all automatically.

• Question 163:

  After an employee connected a switch port of a home router to the wall jack in the office, other employees in the office started losing connectivity. Which of the following can be implemented on the company switch to prevent loss of connectivity in the future?

  A. Loop prevention
  B. ARP inspections
  C. DHCP snooping
  D. MAC address filtering
  A. Loop prevention

• Question 164:

  Which of the following standards can operate at either 20MHz or 40MHz channel spacing?

  A. 802.11a
  B. 802.11b
  C. 802.11g
  D. 802.11n
  D. 802.11n

  ---

  The 2.4 GHz ISM band is fairly congested. With 802.11n, there is the option to double the bandwidth per channel to 40 MHz which results in slightly more than double the data rate. However, when in 2.4 GHz, enabling this option takes up to 82%[10] of the unlicensed band, which in many areas may prove to be infeasible. The specification calls for requiring one primary 20 MHz channel as well as a secondary adjacent channel spaced ?0 MHz away. The primary channel is used for communications with clients incapable of 40 MHz mode. When in 40 MHz mode, the center frequency is actually the mean of the primary and secondary channels.

• Question 165:

  Which of the following WAN technologies decreases bandwidth performance as the distance from the provider increases?

  A. DSL
  B. T1
  C. Frame relay
  D. ISDN
  A. DSL

• Question 166:

  Please refer to the attached exhibit. Which of the following types of configuration management documentation is represented?

  

  A. Network security policy
  B. Network baseline
  C. Logical network diagram
  D. Wiring schematic
  C. Logical network diagram

• Question 167:

  A network technician was in the process of configuring a network device. After restarting the device, it was unresponsive. Additionally, a hard reset did not restore the device to factory defaults, and it did not display any output. Which of the following was the technician MOST likely performing?

  A. Driver update
  B. Firmware update
  C. OS update
  D. Security update
  B. Firmware update

• Question 168:

  A technician is setting up a computer lab. Computers on the same subnet need to communicate with each other using peer to peer communication. Which of the following would the technician MOST likely configure?

  A. Hardware firewall
  B. Proxy server
  C. Software firewall
  D. GRE tunneling
  C. Software firewall

  ---

  A host-based firewall is a computer running firewall softwarethat can protect the computer itself. A software firewall would be the most cost effective in a lab scenario.

• Question 169:

  Which of the following technologies is used to connect public networks using POTS lines?

  A. OC3
  B. OC12
  C. PSTN
  D. Cable
  C. PSTN

  ---

  The PSTN consists of telephone lines, fiber optic cables, microwave transmission links, cellular networks, communications satellites, and undersea telephone cables, all interconnected by switching centers, thus allowing any telephone in the world to communicate with any other

• Question 170:

  A technician is installing new PCs on the network. After installing the latest patches and OS updates, a user is receiving an "unsupported version" error message when accessing a web-based application. Which of the following should the technician perform to fix this issue?

  A. Upgrade SNMP to SNMPv3
  B. Switch from HTTP to HTTPS
  C. Roll back the web browser to a previous version
  D. Roll back the OS to a previous version
  D. Roll back the OS to a previous version
