Question #11
An engineer plugs in a Cisco Aironet 2700 Series Access Point and it is running in low power. Which three power requirements should be verified? (Choose three.)
  1. A
    802.3ac compliant
  2. B
    802.3at compliant
  3. C
    AP requires 43 VDC to function in full power.
  4. D
    AIR-PWRINJ3 power injector should be used.
  5. E
    AP requires 57 VDC to function in full power.
  6. F
    AIR-PWRINJ4 power injector should be used.

Correct Answer:
BEF
The access point should be powered by any 802.3at compliant device.
The recommended external power supply for the access point is the Cisco AIR-PWR-B power supply. The access point can also be powered by the following optional external power sources:

Access point power injector (AIR-PWRINJ4)


Any 802.3af compliant power injector is supported, but in this case the access point will dynamically shift from 3x4 to 3x3.

Question #12
An 802.11n implementation is being discussed. Users are satisfied with the potential 300-450 Mbps throughput of new 802.11n APs. Which three bandwidth requirements are used to calculate per client bandwidth through an 802.11n AP network? (Choose three.)
  1. A
    450 Mbps throughput is the client max for 5-GHz radio.
  2. B
    Channel bonding on 5 GHz is required for a client to have a 300 Mbps WiFi link.
  3. C
    300 Mbps throughput is the client max for 2.4-GHz radio.
  4. D
    The remaining bandwidth is divided per device when more clients are connected to one AP.
  5. E
    100 Mbps Ethernet switch port is a potential bottleneck.
  6. F
    CleanAir helps clear noise for 802.11n channel bonding to work.

Correct Answer:
ACE

Question #13
As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which three areas is the engineer most likely expect to find sources of 2.4 GHz and 5 GHz RF noise? (Choose three.)
  1. A
    emergency room
  2. B
    magnetic resonance imaging
  3. C
    laboratory
  4. D
    X-ray radiography
  5. E
    Gamma Knife radiation treatment
  6. F
    kitchen

Correct Answer:
ACF

Question #14
What is the recommended minimum speed at the edge of the cells in an 802.11g network for a good Cisco VoWLAN deployment?
  1. A
    11 Mb/s
  2. B
    36 Mb/s
  3. C
    12 Mb/s
  4. D
    18 Mb/s

Correct Answer:
C

Question #15
An engineer is installing a wireless network in an industrial area with extreme temperatures and a significant amount of dust. Which enclosure should be used to protect the APs?
  1. A
    ACU
  2. B
    ADU
  3. C
    NEMA
  4. D
    WLSE

Correct Answer:
C
Sometimes access points (APs) are located in areas where they are subject to extreme moisture, temperatures, dust and particles. These APs might need to be mounted inside a sealed enclosure. The NEMA has a rating system for these enclosures, which are generally called NEMA enclosures.
