1. Refer to the exhibit. Which statement accurately represents the characteristics of the core layer
in this design?
A. QoS should be performed only in the core.
B. Load balancing should never be implemented or used in the core.
C. Access lists should be used in the core to perform packet manipulation.
D. It is acceptable to use a partial mesh in the core if it is connected to each device by multiple paths.
E. Policybased
traffic control is implemented in the core to enable prioritization, ensuring the best
performance for all timecritical
applications.
Answer: D
2. Which statement accurately describes one difference between a small office and medium office
topology?
A. Small offices commonly use Rapid PVST+ for Layer 3 deployments.
B. Medium offices commonly use integrated route and switching platforms.
C. Medium offices use integrated 10/100/1000 interfaces as Layer 2 trunks.
D. Medium offices use external access switches to support LAN connectivity. Answer: D
3. Which three factors best justify WAN link redundancy between geographically dispersed sites?
(Choose three.)
A. important traffic flows
B. lack of speed
C. high link utilization
D. uncertain reliability
E. excessive packet transmission rate
F. high expense of transmitting data
Answer: ABD
4. Refer to the exhibit. Which two statements describe why Model A is the recommended design for
routing between Building Distribution switches and Campus Core switches? (Choose two.)
A. It uses timerbased
nondeterministic
convergence.
B. It is softwarebased,
providing fast convergence to the remaining path.
C. Routes are not summarized from distribution to the core.
D. The Layer 3 redundant equal cost links support fast convergence.
E. A link or box failure does not require routing protocol convergence.
Answer: DE
5. An organization needs a WAN Transport technology that meets these criteria: has a low initial cost
provides lowtomedium
BW has mediumtohigh
latency and jitter
Which technology would you suggest?
A. DSL
B. X.25
C. ISDN
D. wireless
E. analog modem
Answer: A
6. Which two of these represent a best practice implementation of a Split MAC LWAPP deployment in a
Cisco Unified Wireless Network? (Choose two.)
A. Each wireless client authentication type maps to a shared SSID which in turn maps to a common
shared VLAN.
B. Each wireless client authentication type maps to a unique SSID which in turn maps to a unique VLAN.
C. Each wireless client authentication type maps to a unique SSID which in turn maps to a common
shared VLAN.
D. 802.1Q trunking extends from the wired infrastructure to the access point for translation into SSID(s).
E. 802.1Q trunking extends from the wired infrastructure to a wireless LAN controller for translation into
SSID(s).
F. 802.1Q trunking extends from the wired infrastructure to a wireless LAN controller. Then the 802.1Q
packet is encapsulated in LWAPP and sent to the access point for transmission over the SSID(s).
Answer: BE
7. Which two statements represent advantages that the topdown
network design process has over the
bottomup
network design process? (Choose two.)
A. is able to provide the big picture
B. utilizes previous experience
C. takes less time to design a network
D. identifies appropriate technologies first
E. provides a design for current and future development
Answer: AE
