CompTIA N10-005 Online Questions & Answers

• Question 91:

  Which of the following connectors are MOST commonly used on a POTS line?

  A. RJ-45
  B. MTRJ
  C. DB-9
  D. RJ-11
  D. RJ-11

  ---

  The six-position plug and jack commonly used for telephone line connections may be used for RJ11, RJ14 or even RJ25, all of which are actually names of interface standards that use this physical connector. The RJ11 standard dictates a 2wire connection, while RJ14 uses a 4-wire configuration, and RJ25 uses all six wires. The RJ abbreviations, though, only pertain to the wiring of the jack (hence the name "registered jack"); it is commonplace but not strictly correct to refer to an unwired plug connector by any of these names. Typically you'll find the RJ-11 and RJ-14 on your Plain Old Telephone Service (POTS)

• Question 92:

  A technician enters a username and password once and can access multiple databases without being prompted to reenter their password. This is an example of which of the following?

  A. Two-factor authentication
  B. Network access control
  C. Multifactor authentication
  D. Single sign-on
  D. Single sign-on

• Question 93:

  Which of the following network access security methods ensures communication occurs over a secured, encrypted channel, even if the data uses the Internet?

  A. MAC filtering
  B. RAS
  C. SSL VPN
  D. L2TP
  C. SSL VPN

  ---

  SSL VPN consists of one or more VPN devices to which the user connects by using his Web browser. The traffic between the Web browser and the SSL VPN device is encrypted with the SSL protocol or its successor, the Transport Layer Security (TLS) protocol.

• Question 94:

  A consultant has been hired to wire a simple small office of ten computers to a layer 2 Ethernet 100BaseT switch. Which of the following cabling will be needed for the installation?

  A. Multimode fiber
  B. RG-59 coaxial
  C. CAT6a
  D. CAT3
  C. CAT6a

• Question 95:

  At which of the following layers do frames exist? (Select TWO).

  A. OSI model Data link layer
  B. TCP/IP model Network Interface layer
  C. OSI model Physical layer
  D. OSI model Network layer
  E. TCP/IP model Internet layer
  A. OSI model Data link layer
  B. TCP/IP model Network Interface layer

  ---

  The data link layer is concerned with local delivery of frames between devices on the same LAN. Data-link frames, as these protocol data units are called, do not cross the boundaries of a local network. Inter-network routing and global addressing are higher layer functions, allowing data-link protocols to focus on local delivery, addressing, and media arbitration. In this way, the data link layer is analogous to a neighborhood traffic cop; it endeavors to arbitrate between parties contending for access to a medium, without concern for their ultimate destination.

• Question 96:

  A technician installs a new CAT6 cable from one end of the office building to another, a total distance of 600 feet (182.88 meters). When a laptop is connected to the cable, it cannot connect to the Internet.

  Which of the following is MOST likely the cause of this problem?

  A. Bad connectors
  B. Crosstalk
  C. DB loss
  D. TXRX reversed
  C. DB loss

• Question 97:

  Which of the following wireless standards uses a block encryption cipher rather than a stream cipher?

  A. WPA2-CCMP
  B. WPA
  C. WEP
  D. WPA2-TKIP
  A. WPA2-CCMP

  ---

  Counter Cipher Mode with Block Chaining Message Authentication Code Protocol or CCMP (CCM mode Protocol) is an encryption protocol designed for Wireless LAN products that implement the standards of the IEEE 802.11i amendment to the original IEEE 802.11 standard. CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC-MAC (CCM) of the AES standard. It was created to address the vulnerabilities presented by WEP, a dated, insecure protocol.

• Question 98:

  Which wireless standard works at a MAXIMUM data rate of up to 54Mbps?

  A. 802.11b
  B. 802.11g
  C. 802.11n
  D. 802.1q
  B. 802.11g

• Question 99:

  A company would like to use the enterprise RADIUS server to authenticate and identify their secure wireless users. Which of the following standards should the company use to facilitate this?

  A. Stateful inspection
  B. WEP
  C. WPA
  D. Open with EAP
  C. WPA

• Question 100:

  A technician would like to connect two separate LAN networks at a small business for a short period of time, to share files. The connection needs to be temporary, and is physically impossible using standard network cabling. Which of the following is the BEST way to connect the networks in this situation?

  A. Wireless repeater
  B. Wireless bridge
  C. Bluetooth
  D. RADIUS server
  B. Wireless bridge
