• Question 265:

  Which of the following is the FASTEST Ethernet technology?

  A. 10GBaseSR
  B. 10BaseT
  C. 100BaseFX
  D. 1000BaseT
  A. 10GBaseSR

  ---

  10GBASE-SR ("short range") is a port type for multi-mode fiber and uses 850 nm lasers. Its Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its Physical Medium Dependent PMD in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbit/s.

• Question 266:

  Which of the following can be used to compromise a WPA encrypted wireless network when the rainbow table does not contain the key?

  A. Evil twin
  B. War chalking
  C. Buffer overflow
  D. Virus
  A. Evil twin

  ---

  An evil twin is the wireless version of the phishing scam. An attacker fools wireless users into connecting a laptop or mobile phone to a tainted hotspot by posing as a legitimate provider.This type of evil twin attack may be used to steal the passwords of unsuspecting users by either snooping the communication link or by phishing, which involves setting up a fraudulent web site and luring people there.

• Question 267:

  Which of the following 802.11 standards can operate at both 2.4Ghz and 5.0Ghz?

  A. Reservations
  B. Lease times
  C. Removing IPs from the active leases
  D. Configuring the DNS options

• Question 269:

  Which of the following protocols resolves IP addresses to MAC addresses?

  A. DNS
  B. ARP
  C. RARP
  D. NTP
  B. ARP

  ---

  ARP is used to convert an IP address to a physical address such as an Ethernet address. ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4, Chaosnet, DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 standards, FDDI, X.25, Frame Relay and Asynchronous Transfer Mode (ATM). IPv4 over IEEE 802.3 and IEEE 802.11 is the most common case.

• Question 270:

  A small company is looking to install a wireless network to enable its relatively old fleet of laptops to have limited internet access internally.
