Network Edge Routers
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?
48 Gb/s, by providing full bandwidth to each port
How much traffic is a 48-port gigabit switch capable of switching when operating at full wire speed?
What is the term that is used for the area of a network that is affected when a device or network service experiences problems?
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?
