Q8. Which two statements about designing the Data Center Access layer are correct? (Choose two.)
A. Multiport NIC servers should each have their own IP address.
B. Layer 3 connectivity should never be used in the access layer.
C. Layer 2 connectivity is primarily implemented in the access layer.
D. Multiport NIC servers should never be used in the access layer.
E. Layer 2 clustering implementation requires servers to be Layer 2 adjacent.
Answer: C,E
Explanation:
User access is primarily layer 2 in nature, layer 2 clustering is possible only in layer 2 Here is the Explanation: from the Cisco press CCDA certification guide Figure 4-8. Enterprise Data Center Infrastructure Overview
Defining the DC Access Layer
The data center access layer’s main purpose is to provide Layer 2 and Layer 3 physical port density for various servers in the data center. In addition, data center access layer switches provide high-performance, low-latency switching and can support a mix of oversubscription requirements. Both Layer 2 and Layer 3 access (also called routed access) designs are available, but most data center access layers are built using Layer 2 connectivity. The Layer 2 access design uses VLAN trunks upstream, which allows data center aggregation services to be shared across the same VLAN and across multiple switches. Other advantages of Layer 2 access are support for NIC teaming and server clustering that requires network connections to be Layer 2 adjacent or on the same VLAN with one another.

Q11. Which Cisco technology using Nexus NX-OS infrastructure allows the network architect to create up to four separate control and data plane instances of the Nexus chassis?
A. virtual port-channel
B. virtual routing and forwarding
C. virtual switching system
D. virtual device context
Answer: D
Explanation:
Virtualization
Virtual local-area network (VLAN), virtual storage-area network (VSAN), and virtual device contexts (VDC) help to segment the LAN, SAN, and network devices instances.
Cisco Nexus 1000V virtual switch for VMware ESX and ESXI help to deliver visibility and policy control for virtual machines (VM).
Flexible networking options with support for all server form factors and vendors, including support for blade servers from Cisco, Dell, IBM, and HP with integrated Ethernet and Fiber Channel switches.

A. Enterprise data center module
B. Enterprise campus module
C. Enterprise edge module
D. Service Provider edge module
E. Service Provider data center module
Answer: B
Explanation:
The network management servers reside in the campus infrastructure but have tie-ins to all the components in the enterprise network for monitoring and management.
Q13. A company requires a managed WAN solution that supports Layer 2 adjacency across remote offices for applications and services. What solution should be selected?
A. DMVPN
B. MPLS
C. VPLS

A. Link-local
B. Site-local
C. Anycast
D. Multicast
E. Global aggregatable
Answer: C
Explanation: Any cast is a network addressing and routing methodology in which data grams from a single sender are routed to the topologically nearest node in a group of potential receivers all identified by the same destination address. Link: http://en.wikipedia.org/wiki/Anycast
