Question: 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: 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.

Question: 3
|
Which features are necessary
in the enterprise aggregation layer? (Select three.)
A. It must support high-speed
traffic delivery.
B. It must be highly
available.
C. It must be flexible.
D. It must take a primary role
in controlling user access to the network.
E. It must take a primary role
in controlling access to network resources.
|
Answer: A, B, C
|
Explanation:
The access is controlled by
access layer. Therefore, the only possible answers are A, B and C.
|
Question: 4
|
As a data center becomes
virtualized and begins to implement cloud computing, how does the traffic flow
typically change?
A. Both north-south
(client-server) and east-west (server-to-server) traffic often increase.
B. The speed and reliability
of storage traffic transmission increases.
C. The traffic flow shifts
from primarily server-to-server to primarily server-to-client.
D. Traffic decreases as more
data is processed locally on users' workstations.
