CompTIA N10-005 Online Questions & Answers

• Question 701:

  A network technician is troubleshooting signal problems with certain WAPs in an office and finds consistently high ping times across the units. Such an issue is called which of the following?

  A. Latency
  B. Attenuation
  C. Crosstalk
  D. Frequency hopping
  A. Latency

  ---

  During the high ping time users are using most of the bandwidth that causes latency so signal strength get affected by this.

• Question 702:

  A Chief Executive Officer (CEO) decided that only a limited number of authorized company workstations will be able to connect to the Internet. Which of the following would BEST accomplish this goal?

  A. Use content filtering
  B. Install and configure IDS
  C. Enable MAC address filtering
  D. Enable RAS on the network firewall
  C. Enable MAC address filtering

  ---

  Most Wi-Fi access points and routers ship with a feature called hardware or MAC address filtering. This feature is normally turned "off" by the manufacturer, because it requires a bit of effort to set up properly. However, to improve the security of your Wi-Fi LAN (WLAN), strongly consider enabling and using MAC address filtering.

• Question 703:

  A user's computer is unable to access the Internet.

  Which of the following utilities can a technician use to determine if DNS is working?

  A. nbstat
  B. arp
  C. nslookup
  D. ipconfig
  C. nslookup

  ---

  nslookup is a network utility program used to obtain information about Internet servers. As its name suggests, the utility finds name server information for domains by querying DNS.

• Question 704:

  Which of the following attacks is spread by attaching themselves to files?

  A. Worms
  B. Botnet
  C. DDoS
  D. FTP bounce
  A. Worms

• Question 705:

  At which of the following layers of the OSI model is the Logical Link Control found?

  A. Layer 2
  B. Layer 3
  C. Layer 4
  D. Layer 5
  A. Layer 2

• Question 706:

  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 707:

  A company wants to have a security zone to isolate traffic within the firewall. Which of the following could be used?

  A. VPN
  B. ACL
  C. DMZ
  D. VLAN
  C. DMZ

• Question 708:

  A network administrator has decided to tighten company security after a recent data breach. The new scheme calls for a strong 10 character password, a special 4 digit pin code, and a one-time use dynamic token that is accessed via a smartphone application.

  Which of the following is being implemented?

  A. Two-factor authentication
  B. Biometric security
  C. Multi-factor authentication
  D. Single factor authentication
  A. Two-factor authentication

• Question 709:

  Under each network device, drag and drop the associated broadcast and/or collison description. Objects may be used multiple times, as needed.

  Select and Place:

  

  

• Question 710:

  A network administrator is tasked with deploying a company-wide wireless system which allows for accurate tracking of employees' wireless device locations via WAP triangulation. Which of the following is the MOST important aspect of the deployment?

  A. WAP placement
  B. TX/RX channel
  C. Signal strength
  D. Transmission power
  A. WAP placement

  ---

  Before going ahead with the deployment, the first thing that need to be check is where you are going to place your wireless router so that you can have internet connectivity from every location that you need.
