Q31. DRAG DROP
Answer:
Q32. What three customer supported details identifies network requirements based on the PPDIOO design model? (Choose three.)
A. goals
B. budget
C. user needs
D. locations
E. policies
F. tasks
Answer: A,B,C
Q33. When selecting which hardware switches to use throughout an enterprise campus switched network, which consideration is not relevant?
A. whether data link layer switching based upon the MAC address is required
B. the number of shared media segments
C. which infrastructure service capabilities are required
D. whether to support Layer 3 services at the network edge
Answer: B
Explanation: Shared media are not used in modern networks; all links are operating full-duplex Link: http://www.cisco.com/en/US/docs/solutions/Enterprise/Campus/campover.html
Q34. Which of these is the equation used to derive a 64 Kbps bit rate?
A. 2 x 8 kHz x 4-bit code words
B. 8 kHz x 8-bit code words
C. 2 x 4-bit code words x 8 kHz
D. 2 x 4 kHz x 8-bit code words
Answer: D
Explanation: While the human ear can sense sounds from 20 to 20, 000 Hz, and speech encompasses sounds from about 200 to 9000 Hz, the telephone channel was designed to operate at about 300 to 3400 Hz. This economical range carries enough fidelity to allow callers to identify the party at the far end and sense their mood. Nyquist decided to extend the digitization to 4000 Hz, to capture higher-frequency sounds that the telephone channel may deliver. Therefore, the highest frequency for voice is 4000 Hz. According to Nyquist theory, we must double the highest frequency, so 2x4kHz = 8kHz.
Each sample will be encoded into a 8-bit code. Therefore 8kHz x 8-bit code = 64 Kbps (notice about the unit Kbps: 8kHz = 8000 samples per second so 8000 x 8-bit = 64000 bit per second = 64 Kilobit per second = 64 Kbps)

Note:
Nyquist theory:
“When sampling a signal (e.g., converting from an analog signal to digital), the sampling frequency must be greater than twice the bandwidth of the input signal in order to be able to reconstruct the original perfectly from the sampled version.”
Q35. A dynamically routed private line and a statically routed IPsec tunnel connect two offices. What routing configuration prefers the IPsec tunnel only in the event of a private line failure?
A. floating static entry
B. EIGRP variance
C. bandwidth metric
D. OSPF maximum paths
Answer: A
Q36. Which three solutions are part of the Borderless Network Services? (Choose three.)
A. Wireless
B. Routing
C. TrustSec
D. MediaNet
E. Switching
F. EnergyWise
G. Next-Gen WAN
Answer: C,D,F
Q37. OSPF will be used as the IGP within a campus network. Which two things should you consider before deployment? (Choose two.)
A. All areas need to connect back to area 0.
B. The OSPF process number on each router should match.
C. NSSA areas should be used when an area cannot connect directly to area 0.
D. Stub areas should be connected together using virtual links.
E. ECMP may cause undesired results depending on the environment.
Answer: A,E
Q38. DRAG DROP
