Fill in the blank.
Reducing the complexity of network design by dividing a network into smaller
areas is an example of a ” hierarchical ” network model.​

20. Match the layer to the corresponding device. (Not all options are used.)

Place the options in the following order:

– not scored – 
core -> high-speed switches
access -> Layer 2 switches
distribution  -> Layer 3 switches

21. Match the submodule to the correct Cisco Enterprise Architecture module. (Not all options are used.)

Place the options in the following order:

Cisco Enterprise Campus

[+] campus core 
[+] building distribution 
[+] data center

Cisco Enterprise Edge

[#] VPN and remote access 
[#] DMZ 
[#] e-commerce

22. Fill in the blank. Use the abbreviation.
Under the Cisco Enterprise Edge module, the submodule that provides remote access including authentication and IPS appliances is the ” VPN ” and remote access submodule.

23. What are two of the top trends that affect network architecture design? (Choose two.)

Internet security

internal security attacks

speed of Internet connectivity

cloud computing*

BYOD*

24. Why would a company want network engineers to adhere to structured engineering principles when designing networks?

The resiliency of a network depends on being able to modify portions of the network, add services, or increase network capacity without adding new hardware devices.

The network is not expected to remain available under abnormal conditions such as extreme traffic loads or denial-of-service events.

The network can be easily designed because of the separation of the various functions that exist on a network into modules.*

A hierarchical network model is a useful high-level tool for designing a reliable network infrastructure, although it increases the complexity of network design.

25. Refer to the exhibit.
