Prepare for the 300-425 with reliable study materials, practice questions, and key exam insights.

Prepare for the 300-425 Designing Cisco Enterprise Wireless Networks (ENWLSD) exam with CertQueen's independently developed study resources. Review important concepts, practice scenario-based questions, and use clear explanations to identify areas that require further study.

Question#1

Campus users report a poor wireless experience. An engineer investigating the issue notices that in high-density areas, the wireless clients fail to switch the AP to which are automatically connected. This sticky client behavior is causing roaming issues.
Which feature must the engineer configure?

A. Load balancing and band select
B. optimized roaming
C. Layer 3 roaming
D. Layer 2 roaming

Question#2

An engineer is designing a new wireless network.
The network needs to meet these requirements:



Which design approach should be taken?

A. 5 GHz frequency band with channel bonding, to support 40 MHz channels
B. 5 GHz frequency band without channel bonding, to support 20 MHz channels
C. 5 GHz frequency band with channel bonding, to support 80 MHz channels.
D. 2.4 GHz frequency band without channel bonding, to support 20 MHz channels

Question#3

An engineer must create data link redundancy for the company’s Cisco Wireless LAN controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy.
Which three features of LAG-based redundancy influenced this decision? (Choose three.)

A. Packets are always sent out on the same port they are received on.
B. All interface traffic passes as long as one port is up.
C. The same port has multiple untagged dynamic interfaces.
D. Interface connection to two separate nonstacked switches is available.
E. Full bandwidth of all links is available.
F. Ports are grouped into multiple LAGs.

Question#4

A wireless engineer is designing a wireless network to support real-time applications over wireless.
Which IEEE protocol must the engineer enables on the WLC so that the number of packets that are exchanged between an access point and client are reduced and fast roaming occurs?

A. 802.11w
B. 802.11r
C. 802.11i
D. 802.11k

Question#5

WLC SSO is set up between two WLCs in a service provider network serving public spaces. On WLC failover, it is noticed that only about half of the original client count is now showing on the secondary WLC, although it is currently showing the role as active.
Which design side case explains the issue?

A. The secondary WLC platform does not support the required client count.
B. The WLCs had not completed database sync before the primary failure.
C. SSO is not configured correctly.
D. Some client sessions were in WebAuth-Req state before failover.
