Cisco 300-425 Online Practice Questions and Exam Preparation

Cisco 300-425 Online Questions & Answers

• Question 111:

  Which Wi-Fi 6 feature allows multiple clients to share the same channel at the same time?

  A. MU-MIMO
  B. OFDMA
  C. Beamforming
  D. RRM
  B. OFDMA

• Question 112:

  An engineer must perform a Layer 2 survey for a mining facility. Which type of antenna does the engineer use in the mine shaft?

  A. omnidirectional
  B. patch
  C. internal
  D. dipole
  A. omnidirectional

  ---

  In a mining facility, especially within mine shafts where the environment can be long and narrow, an omnidirectional antenna is typically used for a Layer 2 survey. This type of antenna radiates RF signal equally in all directions, providing coverage along the length of the shaft.

• Question 113:

  In a stadium deployment, which WLAN design approach is most recommended?

  A. Few APs with maximum power on 2.4 GHz
  B. High-density design with sectorized directional antennas
  C. Ceiling-mounted omni antennas across the stadium bowl
  D. Deploying APs only on one side of the stadium
  B. High-density design with sectorized directional antennas

• Question 114:

  Refer to the exhibit.

  

  An engineer must design a mobility group that has these requirements:

  1.

  The mobility group must consist of five WLCs.

  2.

  All WLCs must run software version 8.0 or later.

  3.

  The WLCs must connect via an IPv4 network.

  4.

  Two of the WLCs must be in an SSO high availability pair.

  Which two configurations must be included in the design? (Choose two.)

  A. All the WLCs must be of the same model or type.
  B. Only WLCs in an SSO high availability pair must use the same virtual IP address.
  C. The WLAN SSID must be consistent across all the WLCs.
  D. All the WLCs must run the same software version.
  E. Each WLC must use the same mobility domain name.
  C. The WLAN SSID must be consistent across all the WLCs.
  E. Each WLC must use the same mobility domain name.

  Controllers do not have to be of the same model to be a member of a mobility group. Mobility groups can be comprised of any combination of controller platforms as long as the controllers are running compatible AireOS versions

• Question 115:

  An enterprise is using the wireless network as the main network connection for corporate users and guests. To wireless network availability. Two Standalone controllers are installed in the head office. APs are connected to the controllers using a round-robin approach to load balance the traffic. After a power cut, the wireless clients disconnect while roaming. An engineer tried eping from the controller but faits. Which protocol needs to be allowed between the networks that the controllers are installed?

  A. IP Protocol 67
  B. IP Protocol 77
  C. IP Protocol 87
  D. IP Protocol 97
  D. IP Protocol 97

  ---

  The protocol that needs to be allowed between the networks where the controllers are installed is IP Protocol 97, which is used for encapsulating IP within IP, often used in network mobility and IP tunneling.

• Question 116:

  Refer to the exhibit.

  

  What is the main reason why the Wi-Fi design engineer took a different approach than installing the APs in the offices, even though that installation provides better coverage?

  A. aesthetics
  B. transmit power considerations
  C. antenna gain
  D. power supply considerations
  A. aesthetics

• Question 117:

  A network engineer is configuring high availability on an access point. What is the maximum number of controllers that can be configured?

  A. 1
  B. 2
  C. 3
  D. 4
  C. 3

  ---

  Explanation Explanation/Reference:So max 2 will be supported on an AP.

• Question 118:

  APs in a remote office recently have been converted from local mode to FlexConnect to take advantage of the local switching. After the change, remote wireless users report voice quality issues and bad quality on wireless IP phones while roaming. A debug is performed, and it is noticed that the 802.11r Fast Transition is not working as expected, like on local mode AP, though the same WLAN configuration is in place. What is the cause of the issue regarding the FlexConnect APs?

  A. They do not support 802.11r FT.
  B. They must be added into AP groups along with a common RF profile.
  C. They must be in a FlexConnect group to support 802.11r FT.
  D. They must be added to AP groups to support fast roaming methods.
  C. They must be in a FlexConnect group to support 802.11r FT.

  ---

  FlexConnect APs must be in a FlexConnect group to support 802.11r Fast Transition (FT). This grouping allows for local authentication and key management, which are necessary for fast roaming methods that improve voice quality and wireless IP phone performance during roaming.

• Question 119:

  What is the recommended overlap percentage for 2.4 GHz coverage cells in a WLAN design?

  A. 5%
  B. 10%
  C. 15?0%
  D. 50%
  C. 15?0%

• Question 120:

  Why is Dynamic Frequency Selection (DFS) important in WLAN design?

  A. To allow use of radar-detected channels in 2.4 GHz
  B. To increase AP transmit power beyond regulations
  C. To enable usage of additional 5 GHz channels while avoiding radar interference
  D. To reduce co-channel interference on 6 GHz
  C. To enable usage of additional 5 GHz channels while avoiding radar interference
