Cisco 300-425 Online Questions & Answers

• Question 91:

  An engineer must ensure that the new wireless LAN deployment can support seamless roaming between access points using a standard based on an amendment to the 802.11 protocol. Which protocol must the engineer selects?

  A. 802.11i
  B. 802.11ac
  C. 802.11r
  D. 802.11e
  C. 802.11r

  ---

  For seamless roaming between access points, the protocol that supports fast transitions is 802.11r. This amendment to the 802.11 standard allows devices to roam quickly by establishing security credentials before moving to the next access point, reducing the time required for reauthentication.

• Question 92:

  A customer has two Cisco 550B WLCs that manage all the access points in their network and provide N+1 redundancy and load balancing. The primary Cisco WLC has 60 licenses and the secondary Cisco WLC has 40. The customer wants

  to convert the N+1 model to an HA model and provide SSO. Configuration must be performed during a maintenance window. After performing all the configurations on both controllers, the config redundancy unit secondary command is issued

  on the secondary Cisco WLC and it fails.

  Which parameter needs to be in place to complete the configuration?

  A. A cable in the RP port
  B. The secondary Cisco WLC needs a minimum of 50 base licenses
  C. The primary Cisco WLC is already set as the secondary unit.
  D. SSO needs to be enabled
  B. The secondary Cisco WLC needs a minimum of 50 base licenses

• Question 93:

  An engineer must assess an existing company WLAN to determine the possibility for future IEEE 802.11ac Wave 2 wireless deployment. The existing WLAN is IEEE 802.11a/n and has IEEE 802.11n and 802. 11a clients. The engineer must advise the customer about support for these older clients on the new APs. What happens with client compatibility?

  A. 802.11ac is backward compatible with 802.11n but not with 802.11a.
  B. 802.11ac is backward compatible with 802.11a but not with 802.11n.
  C. 802.11ac is backward compatible with 802.11a and 802.11n.
  D. 802.11ac is backward compatible with 802.11a and 802.11n.
  C. 802.11ac is backward compatible with 802.11a and 802.11n.

  ---

  IEEE 802.11ac Wave 2 APs are backward compatible with 802.11a/n clients, allowing these devices to connect and communicate with the newer APs, albeit at their respective maximum supported speeds.

• Question 94:

  An engineer is working for a manufacturing company that has a centralized deployment model. Guests at headquarters need wireless access for presentations, demonstrations, and sharing of information. The engineer must provide external users with secure guest access by connecting to anchor controllers on the DMZ. Auto-Anchor Mobility has been selected in the mobility group to accomplish it. Both anchors are configured as part of the mobility group for HQ. Which design approach ensures that clients connect to the primary controller first and are pushed to the secondary if the primary fails?

  A. Set the Anchor priority for the primary controller to 1.
  B. Set the Anchor priority for the secondary controller to 1.
  C. Configure ECMP but weigh the cost to be higher to go to the primary.
  D. Configure ECMP but weigh the cost to be higher to go to the secondary.
  A. Set the Anchor priority for the primary controller to 1.

  ---

  Setting the Anchor priority for the primary controller to 1 ensures that clients connect to the primary controller first. The Anchor priority is a value assigned to each controller within a mobility group to determine the order in which clients should connect to the controllers. A lower priority value has higher precedence. Therefore, by setting the primary controller's Anchor priority to 1, it becomes the preferred controller for client connections. If the primary controller fails, clients are then pushed to the secondary controller, which should have a higher Anchor priority value.

• Question 95:

  A university requires coverage in large outdoor courtyards. Which antenna type should be used?

  A. Omnidirectional outdoor antenna
  B. Patch antenna
  C. Dish antenna
  D. Sector antenna
  A. Omnidirectional outdoor antenna

• Question 96:

  Refer to the exhibit.

  

  An engineer is about to establish a mobility peer connection between a Cisco Catalyst 9800-CL version 16.10.1e and Cisco AireOS 5520 version 8.8.120.0. The data path between the 9800-CL and AireOS 5520 is down, but its control path is up. Based on the configuration, what is the cause of the issue?

  A. The certificate hash key is incorrect, which causes the data path to be down.
  B. Encrypted mobility is being used in the 5520 configuration, which causes the data path to be down.
  C. The data-dtls is disabled on the AireOS 5520 WLC, which causes the data path to be down.
  D. The data-link-encryption configuration is missing from the 9800-CL configuration.
  C. The data-dtls is disabled on the AireOS 5520 WLC, which causes the data path to be down.

• Question 97:

  An engineer must perform an assessment of a customer LAN for a future IEEE 802.11ac Wave 2 wireless deployment All access switches are Fast Ethernet-Capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)

  A. Replace the existing switches with mGig switches.
  B. Replace the existing switches with gigabit switches with 10G uplinks.
  C. Ensure that cable distances between access switches and APs are not longer than 100 meters.
  D. Replace the existing wiring infrastructure with the CAT-7E wiring standard,
  E. Ensure that cable distances between access switches and APs are not longer than 55 meters.
  A. Replace the existing switches with mGig switches.
  C. Ensure that cable distances between access switches and APs are not longer than 100 meters.

• Question 98:

  A wireless engineer must optimize RF performance for multiple buildings with multiple types of construction and user density. Which two actions must be taken? (Choose two.)

  A. Configure Flexconnect groups for each building.
  B. Configure WMM profiles for each building.
  C. Configure AP groups for each area type.
  D. Configure RF profiles for each area type.
  E. Enable DTPC on the network.
  C. Configure AP groups for each area type.
  D. Configure RF profiles for each area type.

  ---

  To optimize RF performance across different buildings and user densities: C. Configure AP groups for each area type - This allows for customized settings for APs serving different areas. D. Configure RF profiles for each area type - RF profiles enable the customization of RF parameters to suit the specific needs of each building or area type. References: The official Cisco ENWLSD 300-425 certification guide will provide more information on RF optimization strategies. https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-10/config-guide/b_cg810/configuring_ap_groups.html

• Question 99:

  Which frequency band provides the widest channel availability for enterprise WLANs?

  A. 2.4 GHz
  B. 5 GHz
  C. 900 MHz
  D. 6 GHz
  D. 6 GHz

• Question 100:

  A wireless engineer is designing a wireless network for a warehouse using access points with internal antennas. Which two elements have a negative effect on the wireless users? (Choose two.)

  A. wireless channels
  B. access point height
  C. client authentication
  D. client authorization
  E. absorption
  B. access point height
  E. absorption

  ---

  In a warehouse setting, the height at which access points are installed can significantly impact the wireless signal. If the access points are placed too high, the signal may not adequately reach the users. Additionally, absorption by materials commonly found in warehouses, such as metal racks and goods, can weaken the wireless signal, negatively affecting the users. https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1250-series/design_guide_c07-693245.html#_Toc309331086
