     HiSec Endpoint security agents on each workstation

   • B

     HiSec Insight advanced threat analytics

   • C

3. Question 3

   Single answer

   An airport authority is choosing the core switches for a new terminal. Its requirements: add ports over the next decade by inserting new line cards, keep forwarding through the failure of a control unit, and act as the core of a campus network serving staff, passengers and airline tenants.

   Which choice best satisfies all three requirements?

   • A

     A pair of fixed CloudEngine S6700 aggregation switches with VXLAN and MACsec, sized for today's ports

   • B

     A stack of fixed CloudEngine S5735 access switches

   • C

     A NetEngine AR8000 router at the terminal core, since it integrates routing, switching, security and wireless

   • D

     A modular CloudEngine S core switch, such as the S8700, with dual-active control units

   Reveal answer

   Correct answer

   • D

     A modular CloudEngine S core switch, such as the S8700, with dual-active control units

   • A

     AirFlash train-to-ground dump

   • B

     Video site backhaul

   • C

     Base station backhaul

   • D

     Backbone and private line transmission

   Reveal answer

   Correct answer

   • A

     AirFlash train-to-ground dump

6. Question 5

   Single answer

   A presales engineer is preparing the opening slide of an enterprise optical briefing for a regional utility. The slide must use Huawei's own strategy framing for where its optical portfolio is heading.

   Which framing does Huawei use for its optical network strategy?

   • A

     SDH modernization that keeps legacy TDM rings as the strategic core

   • B

     Cellular convergence on 5G-A private networks replacing fixed fiber links

   • C

     Wireless-first campus access on Wi-Fi 7 with copper retained as backup

   • D

     Optical-AI Convergence on F5G-A all-optical networks

   Reveal answer

   Correct answer

   • D

     Optical-AI Convergence on F5G-A all-optical networks

7. Question 6

   Single answer

   An electricity utility must connect thousands of distribution-automation terminals on poles across city and rural feeders. Its requirements are reliable delivery of control commands, no trenching to individual poles, a network the utility owns and controls, and coverage that reaches remote feeders.

   Which proposal best meets all four requirements?

   • A

     A utility-operated Smart Grid eLTE private network

   • B

     FTTH passive optical access run to every distribution pole

   • C

     Public carrier 4G subscriptions for every distribution terminal

   • D

     Outdoor Wi-Fi access points mounted along each feeder route

   Reveal answer

   Correct answer

   • A

     A utility-operated Smart Grid eLTE private network

8. Question 7

   Single answer

   A shopping mall operator's campus requirement states that four buildings will connect to the core over existing single-mode fiber runs of several kilometers. The draft configuration lists aggregation and core switches with 10GE optical uplink ports, and the quotation preview contains only those switches.

   What should be checked before the quotation is issued?

   • A

     That the access switches are changed to copper-uplink models so no modules are needed

   • B

     That the core switches are replaced by NetEngine routers so the buildings connect over SD-WAN

   • C

     That optical modules matching the fiber and distance are included

   • D

     That the quotation is issued now and the uplink modules are sourced later outside the configuration

   Reveal answer

   Correct answer

   • C

     That optical modules matching the fiber and distance are included

9. Question 8

   Multiple answer

   A hotel chain plans to let each property break out to cloud applications locally through SD-WAN, while security is delivered from a cloud platform instead of firewalls in every hotel. The presales engineer proposes SASE.
