QUESTION NO: 1
What are two features that routing switches operating in a campus core must support in order to handle the vast amounts of data, voice, and video traffic in the contemporary enterprise LAN? (Select two.)
A. They must support hierarchical QoS technologies and virtual routing and forwarding (VRF) protocols.
B. They must support non-blocking forwarding for large amounts of switched and routed traffic.
C. They must scale with ease.
D. They must take a primary role in controlling security threats, in particular threats on virtualized servers that might never cross the wire.
E. They must take a primary role in determining endpoint compliance with company policies.
Answer: A,B
Explanation: VRF functionality on Layer 3 switches can be used to link VLANs within a campus.
When a large campus wide virtual network becomes too large to remain a single broadcast domain, it must be subdivided. Layer 3 switches supporting VRF are used to break the virtual network into separate VLANs, each of manageable size.
As administrators gain more experience, virtual systems will grow to include larger numbers of servers and storage, and components will spread across the wide area. VRF is the enabling technology for subdividing virtual networks that connect virtual servers with storage.
For non-blocking forwarding, check the following resource:

QUESTION NO: 2
What is an advantage of installing Converged Network Adapter (CNA) NICs on virtualized
servers?
A. One CNA NIC typically costs less than one traditional Ethernet NIC but provides adequate performance for servers that have been optimized with virtualization.
B. CNA NICs enable servers to act as Fiber Channel over Ethernet (FCoE) gateways between SAN and LAN switches.
C. CNA NICs provide the high-speed connection required for servers to receive Fiber Channel over Ethernet (FCoE) traffic.
D. Unlike traditional Ethernet NICs, CNA NICs support IPv6, a necessary protocol for data centers of the future.
