HP Level of certifications: HP currently offers five different levels of certifications. These are: Sales Presales, Integration, Administration and Developer.
HP Description of certifications:
Sales: With HP career paths and certifications one usually starts with the Sales -level certifications, HP Accredited Sales Consultant. This level tests your expertise with networking foundations. This level is essentially the entry level in HP certifications.
Presales: This level is the level that succeeds the Sales level of certifications. Certifications such as HP Accredited Presales Consultant are what this level consists of. This level is essentially the advanced level in HP certification.
Integration: This level is the level that succeeds the Sales and Presales certifications. The Integration network professional basically furthers their knowledge in certain technologies so as to be an expert in a field of Integration.
Administration:This level is the level that succeeds the Integration, Presales and Sales certifications. The Administration network professional basically furthers their knowledge in certain technologies so as to be an expert in a field of Administration.
Developer: This level is the level that succeeds all three of the above-mentioned levels. This level can be considered the equal of a doctorate in networking. This level usually means that you have achieved the highest level.
What are the compulsory exams to earn credit for the different HP certifications?
Every level of the HP certifications has their respective examinations that accompany it. For a detailed list of these examinations see the official HP website.

15. In 802.11a WLANs, what statements are true concerning the use of Orthogonal Frequency Division Multiplexing
(OFDM)?
A. Six (6) “pilot” sub-carriers are used as a reference to disregard frequency and phase shifts of the signal during
transmission.
B. OFDM transmissions in the lower U-NII band are limited to 40 mW.
C. 16QAM modulation is used at the 54 Mbps data rate.
D. The OFDM PHY is divided into two sub-layers, the LLC and PLCP.

Answer: BE

16. You have been hired by ABC Company to troubleshoot their 802.11abgh-compliant, Wi-Fi-certified access point and
wireless client devices. After completing a site survey, you identify five neighboring 802.11b access points belonging
to XYZ Company; one on channel 1, three on channel 6, and one on channel 11. To best avoid co-channel and adjacent
channel interference, what suggested change is most appropriate?
A. Configure ABC Company’s access point to use channel 1, 802.11g OFDM-only mode, and to operate in PCF mode.
B. Configure ABC Company’s access point to use channel 3, 802.11g-standard mode, and to use the RTS/CTS protection
mechanism all the time.
C. Configure ABC Company’s access point to use 802.11a with dynamic frequency selection (DFS).
D. There is no available configuration that would avoid co-channel or adjacent-channel inteference in this situation.
Answer: C

17. What facts should you consider when choosing a spread spectrum technology for your wireless LAN network?
A. An 802.11b Direct Sequence Spread Spectrum (DSSS) signal offers higher data rates and is less susceptible to
narrowband interference than an 802.11 Frequency Hopping Spread Spectrum system.
B. While 802.11g devices can use either DSSS or OFDM technology, 802.11a devices only support OFDM. Therefore
802.11g devices always use OFDM to communicate with 802.11a devices.
C. When 802.11b devices are present in an 802.11g BSS, the use of DSSS will diminish network throughput significantly
over a purely OFDM environment.
D. An 802.11g system supporting only the data rates required by the 802.11g amendment can interoperate with 802.11b
devices.
E. 802.11g systems use OFDM technology to obtain speeds equal to 802.11a systems and to communicate with 802.11b
devices.
Answer: CD

18. What device feature is user configurable for 802.11i-compliant wireless LAN client devices?
A. 802.1Q Tagging
B. SNMP Community Strings
C. TKIP Configuration Parameters
D. RADIUS Server IP Port
E. EAP Authentication Type
Answer: E

19. What IEEE documents specify methodologies for seamless roaming between access points?
A. 802.11j
B. 802.11d
C. 802.11F
D. 802.11s
E. 802.11N
F. 802.11r
Answer: C

20. According to the 802.11g amendment, how much separation is required between the center frequencies of
non-overlapping ERP channels?
A. 10 MHz
B. 11 MHz
C. 20 MHz
D. 22 MHz
E. 25 MHz
F. 30 MHz
Answer: E
