console aux
Match the design model layer to the appropriate network function. (Not all options are used.)
access layer → provides connectivity for the users,
distribution layer → forwards traffic from one local network to another,
core layer → provides a high-speed backbone link between dispersed networks
Which type of router would an enterprise use to allow customers to access content anytime and anyplace, regardless of whether they are at home or work?
The correct answer is: network edge routers
How much traffic is a 48-port gigabit switch capable of switching when operating at full wire speed?
The correct answer is: 48 Gb/s, by providing full bandwidth to each port
Which technology is required when switched networks are designed to include redundant links?
The correct answer is: Spanning Tree Protocol
What is a characteristic of out-of-band device management?
The correct answer is: It requires a terminal emulation client.
A company has deployed four 48-port access layer switches to a switch block. For redundancy each access layer switch will connect to two distribution layer
switches. Additionally, link aggregation will be used to combine 10 Gbps interfaces to form 20 Gbps trunk links from the access layer switches to the distribution layer switches. How many switch ports on the access layer switches will be available in the switch block to support end devices?

What is the function of PoE pass-through?
The correct answer is: allows switches, phones, and wireless access points to receive power over existing Ethernet cables from an upstream switch
Which two methods help to prevent the disruption of network services? (Choose two.)
The correct answers are: installing duplicate equipment to provide failover services, using redundant connections to provide alternate physical paths
Which network design solution will best extend access layer connectivity to host devices?
The correct answer is: implementing wireless connectivity
Which feature could be used in a network design to increase the bandwidth by combining multiple physical links into a single logical link?
The correct answer is: EtherChannel
What is the term that is used for the area of a network that is affected when a device or network service experiences problems?
The correct answer is: failure domain
