HP HPE7-A01 Exam With Confidence Using Practice Dumps

The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna. A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario. References:

The correct answer is B. Spanning-tree instance VLAN mapping.

To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.

According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:

• Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:

Switch D1(config)#spanning-tree mst configuration

Switch D1(config-mst)#instance 1 vlan 501-1000

Switch D1(config-mst)#exit

Switch D1(config)#spanning-tree mst 1 priority 0

Switch D2(config)#spanning-tree mst configuration

Switch D2(config-mst)#instance 2 vlan 1-500

Switch D2(config-mst)#exit

Switch D2(config)#spanning-tree mst 2 priority 0

The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.

The other options are incorrect because:

• A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.
• C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.
• D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

AOS 10 Gateways can have the following personas: Mobility, Branch, and VPN Concentrator1 However, the Mobility persona is only available when configuring a Gateway-only group, which is a group that contains only one gateway device2 The Mobility persona provides Overlay WLAN and (or) wired LAN functionalities for campus networks1 The Branch persona provides the Aruba Instant OS and SD-Branch (LAN + WAN) functionality for branch and microbranch networks1 The VPN Concentrator persona provides VPN termination and routing functionality for remote access networks3 The Edge persona is not a valid option, as it is not a supported device persona for AOS 10 Gateways.
