The APs have to be connected on the same network segment.*


Clustering mode must be enabled on the APs.*

Which technological factor determines the impact of a failure domain?

the role of the malfunctioning device*

Which mode configuration setting would allow formation of an EtherChannel link between switches SW1 and SW2 without sending negotiation traffic?

area 0 authentication message-digest*


ip ospf message-digest-key 1 md5 1C34dE*

when the router has interfaces in different areas*

Which characteristic would most influence a network design engineer to select a multilayer switch over a Layer 2 switch?

ability to build a routing table*

A network designer is considering whether to implement a switch block on the company network. What is the primary advantage of deploying a switch block?

The failure of a switch block will not impact all end users.*

A network administrator enters the spanning-tree portfast bpduguard default command. What is the result of this command being issued on a Cisco switch?

Any switch port that has been configured with PortFast will be error-disabled if it receives a BPDU.*

What are two differences between the Cisco IOS 12 and IOS 15 versions? (Choose two.)

A remote classroom can successfully access video-intensive streaming lectures via wired computers. However, when an 802.11n wireless access point is installed and used with 25 wireless laptops to access the same lectures, poor audio and video quality is experienced. Which wireless solution would improve the performance for the laptops?

Add another access point.*

A network engineer is troubleshooting a single-area OSPFv3 implementation across routers R1, R2, and R3. During the verification of the implementation, it is noted that the routing tables on R1 and R2 do not include the entry for a remote LAN on R3. Examination of R3 shows the following:that all interfaces have correct addressingthat the routing process has been globally configuredthat correct router adjacencies have formedWhat additional action taken on R3 could solve the problem?

Enable the OSPFv3 routing process on the interface connected to the remote LAN.*

When should EIGRP automatic summarization be turned off?

when a network contains discontiguous network addresses*

When will a router that is running EIGRP put a destination network in the active state?

when the connection to the successor of the destination network fails and there is no feasible successor available*
