NEW QUESTION # 100
An engineer is designing a network deployment for a college with six buildings Each building must have a WLC located in the IDF to support the APs. The wireless clients should be able to roam between the APs and the controllers. Which type of wireless architecture should be used?

A. Centralized
B. Distributed
C. Autonomous
D. Cloud

Answer: A

Explanation:
Cloud-based architecture has controllers in the cloud, not on premises. Autonomous architecture means each AP is autonomous and is not managed by a WLC, distributed architecture is another term for autonomous architecture, so the same applies. Centralized architecture, a.k.a. split-MAC architecture is when all APs are managed centrally by WLCs, they do not need to be co-located.

A high-density wireless network is designed. Which Cisco WLC configuration setting must be incorporated in the design to encourage clients to use the 5 GHz spectrum?

A. Cisco Centralized Key Management
B. RRM
C. load balancing
D. Band Select

Answer: D

Explanation:
1: Band Select is a feature on Cisco Wireless LAN Controllers (WLC) that encourages dual-band wireless clients to connect to the less congested 5 GHz band. This helps to balance the client load between 2.4 GHz and
5 GHz and improve overall network performance in high-density environments.
References: Look for information on 'Band Select' in the official Cisco ENWLSD 300-425 certification guide.

NEW QUESTION # 109
How does AP failover priority for access points function when configured with priority 1 or 4?

A. When configured with priority 4, the access point is assigned with the lowest priority level and it is marked as low. This access point fails over after other access points with the higher priority when there is primary controller failure.
B. When configured with priority 1, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.
C. When configured with priority 1, the access point is assigned with the medium priority level and it is marked as medium. This access point fails over after other access points with the higher priority when there is primary controller failure.
D. When configured with priority 4, the access point is assigned with the highest priority level and it is marked as critical. This access point fails over before other access points with the lower priority when there is primary controller failure.

Answer: D

NEW QUESTION # 111
An engineer is designing a wireless network to support high availability. The network will need to support the total number of APs and client SSO. Live services should continue to work without interruption during the failover Which two requirements need to be incorporated into the design to meet these needs? (Choose two.)

A. WLC 7.5 code or more recent
B. controller high availability pair with one of the WLCs having a valid AP count license
C. 10 sec RTT
D. back-to-back direct connection between WLCs
E. redundant WLC

Answer: B,E

Explanation:
To support high availability, the design must include redundant Wireless LAN Controllers (WLCs) to ensure service continuity in case of a failure. Additionally, having a high availability pair with one WLC holding a valid AP count license ensures that all APs can remain connected and services continue without interruption during failover.

NEW QUESTION # 115
An engineer in a branch office that does not have a wired backhaul must ensure that local clients can be switched locally and authenticated centrally. In which mode must the AP be configured?

A. RAP
B. Flex+Bridge
C. MAP
D. Cisco FlexConnect

Answer: D

Explanation:
Cisco FlexConnect mode is designed for branch offices that lack a wired backhaul. It allows APs to switch client data traffic locally while still performing client authentication centrally. This mode provides the flexibility needed for branch deployments, ensuring that client traffic is handled efficiently even if the WAN link to the central site is down.

NEW QUESTION # 121
Which of the following statements best describes the purpose of ARP with respect to CEF?

A. ARP is used to build the FIB.
B. ARP is used to reindex the routing table.
C. ARP is used to build the adjacency table.
D. ARP is used to decrease the amount of time spent searching for an entry within a routing table.

Answer: C

Explanation:
Address Resolution Protocol (ARP) is used by Cisco Express Forwarding (CEF) to build the adjacency table.
CEF is the switching method used by Catalyst switches. Unlike traditional multilayer switching (MLS), which merely caches Layer 3 information received when traffic passes through a switch, CEF attempts to optimize the routing process by reindexing the routing table and then building an adjacency table based on the routing table information. The type of MLS performed by CEF is called topology-based switching; traditional MLS is known as route caching, demand-based switching, and flow-based switching.
The routing table is reindexed by using a binary search method. The reindexed routing table is called the forwarding information base (FIB). Reindexing the routing table reduces the amount of time spent searching for an entry within a routing table.
After the FIB is created, an adjacency table is created to map the appropriate Layer 2 next-hop address or addresses to each FIB entry. ARP is used to retrieve the Layer 2 address information. If multiple Layer 2 next- hop addresses are available for an entry in the FIB, then CEF can employ load balancing for packets headed to that destination.
The final result is a single database of routing information (FIB) is built for the switching hardware.
Two extremely useful commands for verifying CEF are:
show ip cef network address - displays entries in the forwarding information base (FIB) show adjacency detail | begin adjacency address - shows information about a specific adjacency in the adjacency table Both commands are shown below with explanations.
SwitchA# show ip cef 192.168.6.0
192.168.6.0/24, version 302, cached adjacency 192.168.166.5, 0 packets, 0 bytes Via 192.168.166.5, VLAN 185, 0 dependencies Next-hop 192.168.166.5, VLAN 185 Valid cached adjacency Above it can be determined that there is a valid CEF entry for the destination network 192.168.6.0 and that there is a valid cached adjacency to the 192.168.166.5 next hop IP address.
In the command output below, it can be determined that 005565946856 is the MAC address of the
192.168.166.5 next-hop address:
SwitchA# show adjacency detail | begin 192.168.166.5
IP VLAN 185 192.168.166.5(6) 0 packets, 0 bytes
005565946856
