CompTIA N10-006 Online Questions & Answers

• Question 1641:

  Which of the following connection types is used to terminate DS3 connections in a telecommunications facility?

  A. 66 block
  B. BNC
  C. F-connector
  D. RJ-11
  B. BNC

  ---

  A DS3 (Digital Signal 3) is also known as a T3 line with a maximum bandwidth of 44.736 Mbit/s. DS3 uses 75 ohm coaxial cable and BNC connectors.

• Question 1642:

  Which of the following switch features allows for both incoming and outgoing data across physical ports at the same time?

  A. Burst-frame
  B. Full-duplex
  C. Half-duplex
  D. VoIP
  B. Full-duplex

  ---

  Explanation Explanation/Reference:A full-duplex (FDX), or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex, since they allow both callers to speak and be heard at the same time

• Question 1643:

  Which of the following protocols would be used to send email to an email server?

  A. NTP
  B. FTP
  C. SNMP
  D. SMTP
  D. SMTP

• Question 1644:

  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 1645:

  Which of the following STP states indicates an inactivated port due to a loop?

  A. Disabled
  B. Learning
  C. Blocking
  D. Forwarding
  C. Blocking

• Question 1646:

  Which of the following is the only standard that can operate at either frequency?

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

  ---

  Only 802.11n can operate at 2.4 Ghz and 5Ghz

• Question 1647:

  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 1648:

  Ann, a technician, installs a wireless router in a network closet in a large office. She then configures all workstations in various offices on that floor to use the wireless connection. Maximum connection speed at each workstation is 54 Mbps. Some users complain that their network connection is very slow. Which of the following is MOST likely the problem?

  A. Workstations were configured with the wrong connection speed on the wireless adapter.
  B. Users with a slow connection are too far away from the wireless router.
  C. Users that cannot connect are configured on the wrong channel.
  D. Wireless network SSID is incorrect.
  B. Users with a slow connection are too far away from the wireless router.

• Question 1649:

  Which of the following is the OSI layer that handles file compression such as LZMA or DEFLATE?

  A. Layer 3
  B. Layer 5
  C. Layer 6
  D. Layer 7
  C. Layer 6

  ---

  The presentation level is translator between the application and network format. Unlike the lower layers, its concern is with the syntax and semantics of the information transmitted. Most user programs do not exchange random binary bit strings. They exchange data such as names, addresses, dates, etc. Different computers store the data in a different way. In order to allow these computers to transmit the data to each other the presentation layer translates the data into a standard form to be used on the network. Another function is data compression which can be used to reduce the number of bits needed to send the packet of information. Security is also added at this layer by using data encryption and decryption. This prevents others from intercepting the data and being able to decipher the meaning of the bits.

• Question 1650:

  An organization is moving to a new datacenter. During the move, several technicians raise concerns about a system that could potentially remove oxygen from the server room and result in suffocation. Which of the following systems are they MOST likely discussing?

  A. Fire suppression
  B. Mantraps at the entry
  C. HVAC
  D. UPS and battery backups
  A. Fire suppression

  ---

  Firesuppression systems are often deployed in server rooms to prevent a fire destroying all the I.T. equipment. Different fire suppression systems work in different ways. Obviously a fire suppression system that sprays water onto the fire is no good for a server room as the water would do as much damage as the fire. A common fire suppression system used in server rooms is one that suppresses the fire by starving it of oxygen. One way the oxygen can be removed from the server room is to fill the server room withan inert gas such as carbon dioxide.
