What is primary consideration when choosing a routed network design over a traditional campus network design?
A. Layer 3 service support at the network edge
B. the routing protocol choice: open (OSPF) or proprietary (EIGRP)
C. the routing abilities of the host devices
D. the need to control the broadcast domains within the campus core
Correct Answer: A
Section: Design Explanation

There are a number of advantages to using virtualization within the data center module. Which the following two are samples of these advantages?
A. Virtualization consolidates many low-performance devices into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.
B. Virtualization compartmentalizes a single device into a few high-performance devices, providing a more efficient utilization of hardware and increasing the price/performance ratio.
C. Dynamic forcibility eliminates the need to add, reassign, or repurpose resources in the system.
D. Virtualization separates user via different physical networks into groups with visibility into only their logical network.
E. Virtualization provides distinct security policies per physical device.
Correct Answer: AD

Here are some of the common benefits achieved through virtualization techniques:
Better use of computing resources, higher server densities, and simplified server migrations
Provides flexibility for ease of management for adds, reassignments, or repurposingresources
Separation of users groups on the same physical network, enabling traffic isolation
Ability to provide per-department security policies
Reduction in power and space required
Increased uptime and reduced operational costs
or from CCDP guide page 303
Device virtualization allows multiple logical devices of a certain type, which have different roles, to be run inside a single physical device, instead of using separate physical devices for each of these roles. For example, a solution such as VMware ESX, Microsoft Hyper-V, or Citrix XenServer allows you to run multiple virtual machines (servers or PCs) inside a single physical piece of server hardware. Other examples are the use of virtual device context in firewalls, load balancers, or switches. A major benefit of device virtualization is that several low-performance devices can be replaced by one high-performance device. This replacement typically yields a better price-to-performance ratio. Another benefit is the added flexibility that makes it easier to add, reassign, or repurpose resources in the system.
