CompTIA N10-006 Online Questions & Answers

• Question 1431:

  Malicious users have used multiple workstations to target a single server with the intent of preventing legitimate users from accessing the server. This server suffered which of the following types of attack?

  A. DDoS
  B. Trojan
  C. Cross-site scripting
  D. Man in the middle
  E. Replay attack
  A. DDoS

• Question 1432:

  A company wants to ensure that a wireless signal from their WAP only sends down one specific corridor. Which of the following can be done to achieve this?

  A. Disable the SSID.
  B. Change the broadcast channel.
  C. Lower the signal strength.
  D. Change the antennas.
  D. Change the antennas.

• Question 1433:

  Which of the following helps prevent routing loops?

  A. Routing table
  B. Default gateway
  C. Route summarization
  D. Split horizon
  D. Split horizon

  ---

  Routing loops occur when the routing tables on the routers are slow to update and a redundant communication cycle is created between routers. Split horizon, which prevents the router from advertising a route back to the other router from whichit was learned, can be used to resist routing loops. Poison reverse, also known as split horizon with poison reverse, is also used to resist routing loops.

• Question 1434:

  A contractor is setting up and configuring conference rooms for a convention. The contractor sets up each room in the conference center to allow wired Internet access going to individual tables. The contractor measured the distance between the hotel's patch panel to the jack, and the distance is within Cat 5e specifications. The contractor is concerned that the room will be out of speculation if cables are run in each room from the wall jacks. Witch of the following actions should the contractor take to ensure the cable runs meet speculations and the network functions property?

  A. Place a switch at the hotel's patch panel for connecting each room's cables.
  B. Place a switch on each table to ensure strong connectivity.
  C. Place repeaters between the patch panel and the rooms.
  D. Place a switch at the wall jack and run the cables in the room from there.
  A. Place a switch at the hotel's patch panel for connecting each room's cables.

• Question 1435:

  A user with an 802.11n WLAN card is connected to a SOHO network and is only able to connect at 11 Mbps with full signal strength. Which of the following standards is implemented on the network?

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

  ---

  802.11 is a set of IEEE standards that govern wireless networking transmission methods. The 802.11 standards commonly used today to provide wireless connectivity in home or office wireless networks are 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac. 802.11b supports speeds up to 11Mbps and uses the 2.4GHz frequency. In this question, the user is using an 802.11n WLAN card. Although the 802.11n WLAN card can support speeds up to 300Mbps, the user is only able to connect at 11Mbps because the user is connected to a wireless network configured to use 802.11b.

• Question 1436:

  192.168.0.7/8 notation denotes which of the following IPv4 subnet masks?

  A. 255.0.0.0
  B. 255.255.0.0
  C. 255.255.255.0
  D. 255.255.255.255
  A. 255.0.0.0

• Question 1437:

  A technician needs multiple networks, high speeds, and redundancy on a system. Which of the following configurations should be considered for these requirements? (Select TWO).

  A. Routing table
  B. Next hop
  C. Port mirroring
  D. Port monitoring
  E. VLANs
  C. Port mirroring
  E. VLANs

  ---

  Explanation Explanation/Reference:Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic, such as an intrusion detection system, passive probe or real user monitoring (RUM) technology that is used to support application performance management (APM). In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

• Question 1438:

  Which of the following wireless standards would BEST allow a company to utilize new and old devices on the 5GHz spectrum while allowing for the highest possible speeds?

  A. A
  B. B
  C. G
  D. N
  D. N

  ---

  802.11n is an amendment which improves upon the previous 802.11 standards by adding multiple-input multiple-output antennas (MIMO). 802.11n operates on both the 2.4 GHz and the lesser used 5 GHz bands

• Question 1439:

  Which of the following is rated for speeds over 800Mbps?

  A. Coaxial
  B. DB-9
  C. CAT6
  D. CAT5e
  C. CAT6

• Question 1440:

  On which of the following OSI model layers would a MAC address be used?

  A. Network
  B. Data Link
  C. Transport
  D. Physical
  B. Data Link

  ---

  Explanation Explanation/Reference:The ITU-T G.hn standard, which provides high-speed local area networking over existing wires (power lines, phone lines and coaxial cables), includes a complete data link layer which provides both error correction and flow control by means of a selective repeat Sliding Window Protocol.
