Q72. 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
Q73. 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.”
Q74. What is the most compact representation of the following IPv6 address?
2001:db8:0000:0000:cafe:0000:0000:1234
A. 2001:db8::cafe::1234
B. 2001:db8::cafe:0000:0000:1234
C. 2001:db8:0:0:cafe::1234
D. 2001:db8::cafe:0:1234
Answer: C

Q79. Which is part of the Prepare phase of PPDIOO?
A. Obtain site contact information
B. Perform network audit
C. Identify customer requirements
D. Perform gap analysis
Answer: C
Explanation:
Prepare Phase The Prepare phase establishes organization and business requirements, develops a network strategy, and proposes a high-level conceptual architecture to support the strategy. Technologies that support the architecture are identified. This phase creates a business case to establish a financial justification for a network strategy.
