• Question 731:

  A technician notices a newly installed CAT5 cable is longer than the standard maximum length. Which of the following problems would this MOST likely cause?

  A. Split cable
  B. EMI
  C. DB loss
  D. Crosstalk
  C. DB loss

  The maximum length for a cable segment is 100 m per TIA/EIA 568-5-A. If longer runs are required, the use of active hardware such as a repeater or switch is necessary. The specifications for 10BASE-T networking specify a 100metre length between active devices. This allows for 90metres of solid-core permanent wiring, two connectors and two stranded patch cables of 5metres, one at each end.

• Question 732:

  Which of the following security appliances would be used to only analyze traffic and send alerts when predefined patterns of unauthorized traffic are detected on the network?

  A. Host based IPS
  B. Network based firewall
  C. Signature based IDS
  D. Behavior based IPS
  C. Signature based IDS

• Question 733:

  A SOHO company just installed new 802.11a wireless APs. All company laptops have gigabit LAN ports along with wireless-g cards. Which of the following is the issue with this setup?

  A. The laptops will have a max wireless speed of 300Mbps
  B. The wired network is likely not backwards compatible with the gigabit LAN ports on the laptops
  C. The wireless system will only function at a slow 11Mbps
  D. The laptops are only capable of functioning on 2.4GHz spectrum
  D. The laptops are only capable of functioning on 2.4GHz spectrum

• Question 734:

  C. AES
  D. 3DES
  A. PKI

• Question 736:

  The ISP needs to terminate the WAN connection. The connection should be located in the network server room where the company LAN equipment resides. Which of the following identifies the location?

  A. Smart jack
  B. MDF
  C. VPN
  D. 66 block
  B. MDF

  ---

  Short for main distribution frame, a cable rack that interconnects and manages the telecommunications wiring between itself and any number of IDFs. Unlike an IDF, which connects internal lines to the MDF, the MDF connects private or public lines coming into a building with the internal network.

• Question 737:

  Which of the following components of wiring distribution is referred to as the core communications closet for an organization?

  A. MDF
  B. Smart jack
  C. IDF
  D. Demarc extension
  A. MDF

  ---

  MDF stands for Main Distribution Frame and is the main computer room for servers, hubs, routers, DSL's, etc. to reside.

• Question 738:

  A customer wants to keep cost to a minimum and has only ordered a single static IP address from the ISP. Which of the following must be configured on the router to allow for all the computers to share the same public IP address?

  A. VLANs
  B. PoE
  C. PAT
  D. VPN
  C. PAT

  ---

  Port Address Translation (PAT), is an extension to network address translation (NAT) that permits multiple devices on a local area network (LAN) to be mapped to a single public IP address. The goal of PAT is to conserve IP addresses.

• Question 739:

  The application layer in the TCP/IP model is comparable to which of the following layers in the OSI model?

  A. Layer 2

• Question 740:

  A technician has been dispatched to investigate connectivity problems of a recently renovated office. The technician has found that the cubicles were wired so that the network cables were run inside the conduit with the electrical cabling. Which of the following would MOST likely resolve the connectivity issue?

  A. Power-cycle the computers and switches to re-establish the network connection.
  B. Re-run the network cabling through the ceiling alongside the lights to prevent interference.
  C. Test the wiring in the network jacks for faults using a cable verifier.
  D. Re-run the network cabling so that they are 12 inches or more away from the electrical lines.
  D. Re-run the network cabling so that they are 12 inches or more away from the electrical lines.
