CompTIA N10-006 Online Questions & Answers

• Question 661:

  Which of the following is the MAXIMUM data transmission rate of 802.11a?

  A. 8Mbps
  B. 11Mbps
  C. 54Mbps
  D. 107Mbps
  C. 54Mbps

• Question 662:

  Which of the following LAN technologies is used to provide a MAXIMUM bandwidth of 1Gbps through singlemode fiber?

  A. 10GBaseLR
  B. 100BaseFX
  C. 100BaseTX
  D. 1000BaseX
  D. 1000BaseX

  ---

  Explanation Explanation/Reference:1000BaseX identifies various Gigabit Ethernet physical layer standards as defined in IEEE802.3z, such as 1000BaseLX, 1000BaseSX, 1000BaseCX and 1000BaseLH. Basically, all standards included in 1000BaseX uses 8B/10B coding scheme with 8 bits of data and 2 bits of error-correction data. Each specification allows various cable (fiber or copper) lengths, and uses different cable media.

• Question 663:

  A technician is helping a SOHO determine where to install the server. Which of the following should be considered FIRST?

  A. Compatibility requirements
  B. Environment limitations
  C. Cable length
  D. Equipment limitations
  B. Environment limitations

  ---

  SOHO stands for Small Office / Home Office. A SOHO network istypically a small network. Being a small network, it is unlikely that it will have a datacenter or even a dedicated server room. Any servers installed in the network will still have the same environmental requirements as servers in a large network. The servers should be in a secure isolated area if required. The servers also need to be kept cool and dry. Therefore, the first consideration in a SOHO office is "Environment limitations": where the servers and other network hardware will be located.

• Question 664:

  A technician finds that the network card is no longer functioning. At which of the following OSI layers is the problem occurring?

  A. Layer 1
  B. Layer 3
  C. Layer 5
  D. Layer 7
  A. Layer 1

• Question 665:

  An assistant systems analyst reports the following findings of an investigation of slow Internet connections in a remote office to the senior systems analyst:

  

  Which of the following devices is causing the issue?

  A. Router
  B. Firewall
  C. Switch 1
  D. Switch 2
  C. Switch 1

• Question 666:

  A strong network firewall would likely support which of the following security features for controlling access? (Select TWO).

  A. War driving
  B. War chalking
  C. MAC filtering
  D. FTP bouncing
  E. Port filtering
  C. MAC filtering
  E. Port filtering

  ---

  MAC filtering set the security level at layer 2 and port filtering will set the security level on layer 4 so by filtering the traffic on both layers our network will get secure.

• Question 667:

  A network engineer is designing a wireless network that uses multiple access point for complete coverage. Which of the following channel selections would result in the LEAST amount of interference between each access point?

  A. Adjacent access point should be assigned channels 1, 6, and 11 with a 20MHz channel width.
  B. Adjacent access points should be assigned channels 2,6, and 10 with a 20MHz channel width.
  C. Adjacent access points should be assigned channels 7 and 11 with a 40MHz channel width.
  D. Adjacent access points should be assigned channels 8 and 11 with a 40MHz channel width.
  A. Adjacent access point should be assigned channels 1, 6, and 11 with a 20MHz channel width.

  B. ACL
  C. DMZ
  D. VLAN
  C. DMZ
