問題 #121
Users who leave the office with a wireless headset must be able to hand oft the voice call with minimal disruption. The engineer drafted four possible Door plans for AP placement:
* red dots and arrows represent the direction of travel
* blue dots represent the AP placements
Which floor plan provides the requested functionality?
A)

B)

C)

D)

  • A. Floor plan A
  • B. Floor plan D
  • C. Floor plan C
  • D. Floor plan B

答案：D

解題說明：
VoWLAN handoff quality is fundamentally determined by the AP placement strategy relative to the direction of user movement. When a user is in motion carrying an active voice call, the roaming event must occur before signal quality degrades below the minimum acceptable VoWLAN threshold (typically -67 dBm for voice, with a minimum SNR of 25 dB). This requires the user to encounter increasing signal strength from a neighboring AP before the current AP ' s signal drops below the threshold. The optimal AP placement follows the principle of overlapping coverage along the predicted path of travel - APs must be positioned so that as a user moves, they progressively enter the coverage zone of the next AP while still within adequate range of the current one. Floor plan B represents the correct design where APs are positioned along the travel path with sufficient cell overlap (typically 15-20%) to ensure seamless 802.11r fast BSS transitions. Incorrect floor plans place APs perpendicular to travel direction, at path endpoints only, or with insufficient overlap zones - all of which create roaming dead zones where the handoff occurs too late, causing voice call disruption.

問題 #122
An engineer is designing a wireless network in a historic building that has large rooms and ornate wall coverings. Which approach must be considered first when placing access points?

  • A. RF coverage
  • B. aesthetics
  • C. RF interference
  • D. cell overlap

答案：A

解題說明：
When designing a wireless network for any environment, including a historic building with ornate wall coverings and aesthetic constraints, RF coverage must always be considered first when placing access points.
RF coverage is the fundamental requirement - without adequate signal strength throughout the space, no other design objective can be met. The engineer must first determine AP locations that provide the required signal strength and coverage to all areas before addressing aesthetics, overlap calculations, or interference mitigation. In a historic building specifically, the ornate wall coverings and dense construction materials may cause unexpected signal attenuation, making it even more important to model RF coverage before committing to AP positions. Once RF coverage requirements are established, aesthetic concerns (Option A) can guide the choice of AP form factor, enclosures, or cabling routes. Cell overlap (Option C) is derived from coverage calculations. RF interference (Option D) analysis follows after RF coverage baseline is established.

問題 #123
A customer has two Cisco 5520 WLCs that manage all APs throughout the network. The WLCs are in different locations to provide geographical redundancy. A mobility group has been configured on both WLCs and has an UP status on both controllers. The APs in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline, the APs successfully join the WLC in location B, but they do not fail over to their primary configured controller when it recovers.
Which configuration task fixes the issue?

  • A. Configure the WLC in location A as primary using the CAPWAP AP Controller IP Address command on all the location A access points.
  • B. Change the AP Failover Priority to critical.
  • C. Enable AP fallback globally on the WLC.
  • D. Use DHCP Option 43 and specify WLC in location A as primary.

答案：C

解題說明：
Enabling AP fallback globally on the WLC allows access points to reconnect to their primary controller after they have connected to a secondary controller due to the primary being offline. This is the exact behavior described in the scenario - APs successfully fail over to the secondary WLC but do not return to the primary WLC when it recovers. AP Fallback is a WLC-level setting that monitors the availability of each AP ' s configured primary controller and initiates a reconnection when the primary becomes reachable again.
Without AP Fallback enabled, APs remain on whatever controller they most recently joined - in this case, the secondary - even after the primary recovers. The CAPWAP AP Controller IP Address command (Option A) permanently changes the primary controller configuration on the AP, which is not the intended solution - the AP already has the correct primary configured. DHCP Option 43 (Option B) is used for initial AP discovery, not fallback. AP Failover Priority (Option D) controls which APs are processed first during a failover event, not whether APs return to their primary controller. Reference: WLSD Study Guide - AP Fallback Configuration, N+1 Redundancy Recovery, Controller Primary/Secondary Hierarchy.


問題 #124
A wireless engineer is getting ready to perform a predictive site survey. The new network needs to support data and voice over wireless. Which two Cisco recommendations should be considered for the design? (Choose two.)

  • A. Set -19 dBm of separation between APs on the same channel.
  • B. Use the 5 GHz radio band due to the 24 non-overlapping channels.
  • C. Use the 5 GHz radio band due to 40 MHz bandwidth capability.
  • D. Set the cell overlap to 15%
  • E. Set the cell boundary to -67 dBm.

答案：C,E

解題說明：
For a network supporting both data and voice over wireless, two key Cisco design recommendations apply. First, the 5 GHz radio band is recommended for voice over wireless due to its wider channel bandwidths, allowing for higher data rates and better quality of service for latency-sensitive applications. 40 MHz channels in the 5 GHz band provide significantly higher throughput than 20 MHz channels in 2.4 GHz, making Option B correct for the bandwidth reason stated. Second, setting the cell boundary to -67 dBm ensures sufficient signal strength for reliable voice communication at the cell edge, which is the Cisco standard threshold for VoWLAN coverage.


問題 #125
A conference center is designing a Wi-Fi 6 deployment for a room holding 2000 attendees, most of whom will use low-bandwidth applications. Which Wi-Fi 6 capability most directly improves efficiency in this scenario?

  • A. 160 MHz channel bonding
  • B. 1024-QAM modulation
  • C. OFDMA subcarrier allocation
  • D. Target Wake Time

答案：C

解題說明：
The defining problem in a high-density room with many low-bandwidth clients is not raw per-client throughput but the overhead of medium contention - under 802.11ac, each small packet requires a full channel access cycle, so the channel spends most of its airtime on contention and preamble rather than payload. OFDMA divides the channel into resource units so the AP can serve multiple clients within a single transmit opportunity, dramatically reducing per-frame overhead when the traffic mix is many small transmissions. This is precisely the profile of a conference audience running chat, email, and browsing. 1024-QAM raises peak modulation but only benefits clients already at very high signal levels and does nothing for contention. 160 MHz channel bonding is counterproductive in high density because it collapses the number of reusable channels. Target Wake Time improves client battery life by scheduling wake intervals, which is valuable for IoT but does not address the airtime efficiency problem in this design.
