HP HPE6-A86 Online Questions & Answers

• Question 11:

  A customer is planning to replace their current HPE Aruba Networking 2930F switches, which are configured using VSF stacking.

  The proposed replacement switches are HPE Aruba Networking CX 6200 models.

  What is the key difference between the stacking features of the current and proposed solutions?

  A. The VSF feature is enabled by default.
  B. VSF MAD is enabled by default on each LAG when LACP active mode is set.
  C. The VSF feature is disabled by default.
  D. The VSF member ID must be set individually for each member.
  A. The VSF feature is enabled by default.

  ---

  Explanation

  The key difference identified here is that VSF is enabled by default on the proposed CX 6200 model family compared with the current AOS-S replacement context. The other choices describe MAD or member-ID details that are not the main default-behavior difference asked.

• Question 12:

  New IoT devices cannot obtain an IP address from a DHCP server at 10.200.1.51.

  Based on the output below, what should you configure to resolve the issue?

  

  A. Disable Spanning Tree on the interface.
  B. Configure an IP helper for the DHCP server.
  C. Configure a static route to the DHCP server.
  D. Configure broadcast to unicast conversion.
  B. Configure an IP helper for the DHCP server.

  ---

  Explanation

  Clients on a different subnet need DHCP relay on the gateway SVI, using an IP helper address that points to the DHCP server. Static routing alone does not relay DHCP broadcasts, and disabling spanning tree or converting broadcasts is not the correct DHCP relay fix.

• Question 13:

  Which customer use case would be ideal for an HPE Aruba Networking Central On-Premises deployment?

  A. Customers who have server resources hosted by hyperscalers
  B. Customers who need a management platform maintained as SaaS
  C. Customers that do not allow cloud connectivity
  D. Customers who need geographical redundancy for the management platform
  C. Customers that do not allow cloud connectivity

  ---

  Explanation

  Central On-Premises is appropriate for customers that require local management and do not permit cloud connectivity. Customers that want SaaS operation, hyperscaler-hosted resources, or cloud-managed redundancy are better aligned with cloud Central rather than an on-premises deployment.

• Question 14:

  Based on the given output:

  router ospf 1

  redistribute connected route-map ospf-redist area 0.0.0.0

  Which HPE Aruba Networking CX switch can be used to create this configuration?

  A. CX 6300
  B. CX 4100i
  C. CX 6000
  D. CX 6100
  A. CX 6300

  ---

  Explanation

  The OSPF redistribution configuration requires a switch family that supports the necessary dynamic routing features, and the CX 6300 is the matching choice. The CX 4100i, CX 6000, and CX 6100 are not the right platforms for this OSPF configuration requirement.

• Question 15:

  A voice deployment shares the same access network as ordinary data traffic.

  Which feature helps prioritize latency-sensitive traffic during congestion?

  A. QoS
  B. ARP
  C. LLDP
  D. NTP
  A. QoS

  ---

  Explanation

  QoS classifies and prioritizes traffic so latency-sensitive voice or collaboration flows can receive better treatment during congestion. ARP, LLDP, and NTP support other network functions and do not provide congestion prioritization.

• Question 16:

  At which layer of the OSI model does data segmentation occur?

  A. Application Layer
  B. Transport Layer
  C. Data Link Layer
  D. Network Layer
  B. Transport Layer

  ---

  Explanation

  Segmentation and reassembly of application data are transport-layer functions. TCP operates at the Transport Layer and uses segments, while the Network Layer handles packets and addressing, and the Data Link Layer handles frames.

• Question 17:

  Which two statements correctly describe VLANs on an access switch?

  A. A VLAN creates a separate Layer 2 broadcast domain.
  B. Traffic between different VLANs requires a Layer 3 forwarding function.
  C. All VLANs automatically share the same broadcast domain.
  D. A VLAN removes the need for IP addressing on hosts.
  A. A VLAN creates a separate Layer 2 broadcast domain.
  B. Traffic between different VLANs requires a Layer 3 forwarding function.

  ---

  Explanation

  A VLAN is a separate Layer 2 broadcast domain, and communication between different VLANs requires Layer 3 forwarding such as routing on an SVI or router. VLANs do not automatically share broadcasts and do not remove the need for host IP addressing.

• Question 18:

  When explaining the HPE Aruba Networking CX Virtual Switching Framework functionality on a CX 6200F switch to a customer, which statement about VSF ports is true?

  A. The port becomes a routed port.
  B. The port speed is set to 10,000-full state and MTU 9198.
  C. The port is removed from the switch's data plane.
  D. The port becomes a member of the ISL LAG.
  C. The port is removed from the switch's data plane.

  ---

  Explanation

  When a physical port is configured as a VSF port, it is dedicated to stack interconnect traffic and removed from the normal data plane. It does not operate as a routed port or ordinary ISL LAG member for user traffic.

• Question 19:

  The customer plans to roll out new HPE Aruba Networking CX 6000 and CX 6100 switches to replace the existing AOS-S switches.

  To make the deployment include fewer manual tasks, the customer has asked how Zero Touch Provisioning, or ZTP, would help with the transition.

  Select the correct statement about ZTP.

  A. The ZTP deployment is enabled by default on the management interface.
  B. ZTP connects to HPE Aruba Networking Central and downloads the template configuration over SCP.
  C. An SFTP server needs to be set up for the switch to download the initial configuration.
  D. A DHCP server needs to be configured with the required options.
  D. A DHCP server needs to be configured with the required options.

  ---

  Explanation

  ZTP relies on DHCP-supplied provisioning information so a factory-default switch can locate its initial software or configuration resources. The process is not simply enabled on every management interface and is not limited to an SCP or SFTP-only download statement.

• Question 20:

  How many collision domains are shown in the diagram below?

  

  A. 1
  B. 2
  C. 3
  D. 6
  D. 6

  ---

  Explanation

  Each switched endpoint link is a separate collision domain in a modern switched Ethernet topology.

  Counting the six individual switched links gives six collision domains, while one, two, or three would undercount the per-link separation.
