Cisco 300-425 Online Questions & Answers

• Question 171:

  Which statement about creating a mobility group is true, excluding mobility anchors?

  A. Each WLC must use the same mobility name and be defined as a peer in each other's static mobility members list.
  B. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair considered separately as a mobility peer.
  C. The WLCs do not have to be of the same model or type to be a member of a mobility group, however each member should be running different software versions.
  D. A mobility groups does not require all WLCs in the group to use the same virtual IP address.
  A. Each WLC must use the same mobility name and be defined as a peer in each other's static mobility members list.

  ---

  Creating a mobility group requires that all Wireless LAN Controllers (WLCs) share the same mobility group name. This allows them to recognize each other as peers and participate in client mobility events. The WLCs must be defined as peers in each other's static mobility members list to facilitate inter-controller communication and roaming.

• Question 172:

  A network engineer must design a new wireless solution for a company, but the budget can only stretch to include a single Cisco 9800-40 WLC. The company requires high availability between the WLC and the core switch in the event of a cable failure. The WLC must dynamically manage port redundancy and perform load balancing between APs transparently. Which design approach must the engineer take to meet the requirements?

  A. LAG
  B. Multi-LAG
  C. LACP
  D. PAgP
  A. LAG

  ---

  Link Aggregation Group (LAG) allows multiple physical ports to be combined into a single logical channel. In the scenario where only one Cisco 9800-40 WLC is available and high availability is required, LAG can be used to manage port redundancy and perform load balancing between APs transparently. This ensures that if one cable fails, the others can continue to carry the traffic without any perceived downtime

• Question 173:

  Refer to the exhibit.

  

  Client A is roaming from AP1 on WLC1 to AP2 on WLC2. The client roams between two APs registered to two different controllers. The WLAN on the two controllers is on a different subnet. Which scenario explains the client's roaming behavior?

  A. The client database entry is different than that of Layer 2 roam. (Instead of copying, it moves the database to the new controller.)
  B. The client database entry is different than that of Layer 2 roam. (Instead of moving, it copies the database to the new controller.)
  C. The client database entry is different than that of Layer 2 roam because the client database is neither moved nor copied into the new controller.
  D. The client database remains in the mobility anchor controller and it is not copied or moved.
  B. The client database entry is different than that of Layer 2 roam. (Instead of moving, it copies the database to the new controller.)

  ---

  When Client A roams from AP1 on WLC1 to AP2 on WLC2 across different subnets, this is considered a Layer 3 roam. Unlike Layer 2 roaming where the client's database entry moves with them, in Layer 3 roaming, the client's database entry is copied to the new controller (WLC2). This ensures continuity of service as Client A transitions between access points managed by different wireless LAN controllers.

• Question 174:

  Refer to the exhibit.

  

  A company is designing a Cisco wireless solution that has two WLCs named WLC1 and WLC2 and several APs. An AP named AP12 is a critical AP and is provisioned to be installed in hallway 6, which is located just outside the office of the company director and must always connect to WLC1.

  Which priority level must be incorporated in the design for AP12?

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

• Question 175:

  A wireless engineer is hired to design a network for a technology company. The company campus has four buildings and a warehouse with access points that provide full wireless coverage as well as a pair of WLCs located in the core of the network. Which type of wireless architecture is being used?

  A. unified deployment
  B. autonomous deployment
  C. centralized deployment
  D. distributed deployment
  C. centralized deployment

  ---

  The wireless architecture described is a centralized deployment. This is characterized by access points distributed across multiple buildings and managed centrally by Wireless LAN Controllers (WLCs). Centralized deployments are common in larger environments like a technology company campus because they allow for centralized management, scalability, and advanced features such as load balancing and fault tolerance.

• Question 176:

  An engineer is trying to configure the APs installed in a new auditorium to use 40 MHz channels with high data rates and lower TX power. The APs in the building hallway must use lower-density design settings configured for the rest of the building. Which two configurations achieve this design? (Choose two.)

  A. TPC
  B. DCA
  C. AP group
  D. RRM
  E. RF profile
  C. AP group
  E. RF profile

• Question 177:

  A network engineer is retrofitting an existing building wired with Category 5e with Cisco Aironet 3800 Series APs and mGig switches. Which cable length allows for 5G operation?

  A. 70 m
  B. 120 m
  C. 130 m
  D. 150 m
  A. 70 m

• Question 178:

  In a multifloor office building that contains an auditorium in the basement, all the access points are joined to the same WLC. The plan is to implement a high-density, high-speed design in the auditorium and a low-density VoWiFi design in the offices. How must the access point groups be configured for the auditorium and the offices?

  A. To all the access points, apply one RF profile that supports Vo WLAN.
  B. Join the access points in each area to area-specific access point groups that have separate RF profiles.
  C. To all the access points, apply one RF profile that supports high speed.
  D. Join the access points in each area to different controllers that have separate RF profiles.
  B. Join the access points in each area to area-specific access point groups that have separate RF profiles.

• Question 179:

  During a post-deployment site Survey, issues are found with non wi-Fi interference. What should the engineer use to identify the source of the Interference?

  A. Network analysis module
  B. Wireless intrusion prevention
  C. Wireshark
  D. Cisco spectrum expert
  D. Cisco spectrum expert

  ---

  Cisco Spectrum Expert is a tool designed to identify and analyze non-Wi-Fi interference sources. During a post-deployment site survey, it can be used to detect interference from various devices such as cordless phones, Bluetooth devices, microwave ovens, and more. This tool provides a visual representation of the RF environment, allowing engineers to pinpoint the exact source of interference and take appropriate measures to mitigate its impact on the wireless network.

• Question 180:

  A customer celled with a requirement that internal clients must be on different subnets depending on the building they are in, AH access points are operating in local mode and will not be modified, and this is a single controller solution. Which design approach creates the desired result?

  A. Create an SSID, place it to the desired VLAN under WLANs, and configure 802 lx in ISE to assign the correct VLAN based on the SSID from which the client is authenticating.
  B. Create FlexConnecI groups, place the access points in. and sat the correct VLAN to SSID mapping based on location.
  C. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.
  D. Create mobility anchors for the SSID, and on the controller under the internal SSID. create a foreign map to the desired VLAN based on location.
  C. Create AP groups for each desired location, map the correct VLANs to the internal SSID, and add the access points for that location.

  ---

  AP groups allow the mapping of specific WLANs (SSIDs) to distinct VLANs for different locations. This design enables clients to be on different subnets based on their building location without modifying the access points' mode of operation.
