Authentic HP Certification Exam HPE6-A47 Questions Answers

it meets the customer’s requirements for wired network upgrade. By combining the switches in each Building 2 closet as a Virtual Switching Framework (VSF) fabric, the architect can reduce the number of logical devices within the network, simplifying management and reducing complexity, aligning with the goal of flattening architecture. Establishing two 10 GbE connections to the core per fabric ensures redundancy and resilience, maintaining connectivity even if one link fails, without necessitating additional cabling. This also provides sufficient bandwidth and scalability for the network traffic.

The other options are incorrect because:

• A. Using two additional 2930F switches to act as an aggregation layer for Building 2 adds another layer of devices and complexity to the network, contradicting the goal of flattening architecture. It also requires additional cabling and ports to connect the switches to the core and the access layer.
• B. Connecting each Building 2 switch directly to the core on a single fiber strand through the use of SFP±SR transceivers does not provide redundancy and resilience, as one link failure would disconnect the switch from the core. It also limits the bandwidth and scalability of the network, as each switch would have only one 10 GbE connection to the core.
• D. Extending additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core requires recabling, which the customer wants to avoid. It also increases the cost and complexity of the network, as more fiber strands and ports would be needed.

The switch needs to support PoE+ for this deployment. PoE+ stands for Power over Ethernet Plus, and it is a technology that allows the switch to provide both data and power to the connected devices over a single Ethernet cable. This eliminates the need for separate power sources or adapters for the devices, and simplifies the installation and management of the network. PoE+ can provide up to 30 watts of power per port,which is sufficient for the Aruba 320 Series APs, which have a maximum power consumption of 20 watts. PoE+ also supports 1 GbE connectivity, which meets the customer’s requirement.

The other options are not relevant for this deployment:

• Option B is incorrect because LACP is not a feature that the switch needs to support for this deployment. LACP stands for Link Aggregation Control Protocol, and it is a protocol that allows multiple physical links to be combined into a single logical link, providing higher bandwidth and redundancy. However, the architect plans to connect each AP with one Ethernet port to the switch, so there is no need for link aggregation in this scenario.
• Option C is incorrect because port channel is not a feature that the switch needs to support for this deployment. Port channel is another term for link aggregation, which is not required for this scenario, as explained above.
• Option D is incorrect because Smart Rate is not a feature that the switch needs to support for this deployment. Smart Rate is a technology that allows the switch to provide multi-gigabit Ethernet speeds (up to 10 GbE) and PoE+ to the connected devices, depending on the cable type and length. However, the customer only wants to support at least 1 GbE connectivity, which can be achieved with PoE+ and CAT6 cable, without the need for Smart Rate.

A wide sector directional antenna is a type of antenna that radiates or receives radio waves in a sector-shaped pattern, covering a wide angle of a circle. The width of the sector is determined by the horizontal beamwidth (H-plane) of the antenna, while the height of the sector is determined by the vertical beamwidth (E-plane) of the antenna12. A wide sector directional antenna is usually used to provide regional coverage for wireless networks, such as Wireless Internet Service Providers (WISP) or similar applications2.

According to the antenna specifications given, Antenna 3 has the widest horizontal beamwidth of 100 degrees, which means it can cover a large sector of a circle. Antenna 4 has a narrower horizontal beamwidth of 60 degrees, which means it can cover a smaller sector of a circle. Antenna 1 and Antenna 2 have a horizontal beamwidth of 360 degrees, which means they are omnidirectional antennas, not directional antennas. Therefore, Antenna 3 is the best choice for the plan that specifies wide sector directional antennas.
