All enterprise networks must: |
Support critical applications Support diverse business needs Provide centralized administrative control |
|
Cisco Enterprise Architecture |
Divides the network into functional components while still maintaining the core, distribution, and access layers.
|
|
A failure domain |
A failure domain is the area of a network that is impacted when a critical device or network service experiences problems. |
|
Enterprise Architecture |

5 categories of switches for enterprise networks |
|
|
Aggregation switches |
Carrier-grade Ethernet switches that aggregate traffic at the edge of a network. |
|
Service provider Ethernet access switches |
Features application intelligence, unified services, virtualization, integrated security, and simplified management. |
|
When selecting switches, network administrators must determine the switch form factors: |
|
|
Thickness of switch |
The thickness of the switch, which is expressed in the number of rack units, is also important for switches that are mounted in a rack. |
|
Business considerations when selecting switch equipment |
|
|
Cisco Catalyst 2960-C and 3560-C Series compact switches |
Support PoE pass-through. PoE pass-through allows a network administrator to power PoE devices connected to the switch, as well as the switch itself, by drawing power from certain upstream switches.
|
|
Routers also serve other beneficial functions: |
|
|
3 categories of routers |
|
|
Out-of-band management |
Used for initial configuration or when a network connection is unavailable. Configuration using out-of-band management requires:
|
|
Configuration using in-band management requires: |
At least one network interface on the device to be connected and operational Telnet, SSH, or HTTP to access a Cisco device
|
|
features of enterprise class equipment assists an enterprise network in maintaining 99.999 percent up-time: |
|
|
How can an enterprise network be designed to optimize bandwidth? |
by organizing the network to control traffic patterns |
|
Which technology is required when switched networks are designed to include redundant links? |
Spanning Tree Protocol |
|
Cisco Meraki switches? |
They are cloud-managed access switches that enable virtual stacking of switches |
|
In which situation would a network administrator install a Cisco Nexus Series or Cisco Catalyst 6500 Series switch to promote infrastructure scalability? |
on a data center network to provide expansion and transport flexibility |
|
Why would a network administrator issue the show cdp neigbors command on a router? |
to display device ID and other information about directly connected Cisco devices |
|
What is a characteristic of in-band device management? |
It is used to monitor and make configuration changes to a network device over a network connection. |
