最新的 HPE Networking HPE7-A12 免費考試真題 (Q34-Q39):

問題 #34
You have designed a two-tier L2 data center network for a customer. When you are presenting the solution, the customer indicates that they have a mission-critical multicast application with sources and receivers in the data center. Which CX feature, beyond features provided by the PIM-SM standard, should you explain to emphasize the value of your solution?

A. PIM-SM active-active with VSX which enables near instant failover for multicast streams if one core switch fails
B. VSX active forwarding, which enables multiple switches to act as PIM-SM active designated routers at the same time
C. Bootstrap router (BSR) support, which makes the solution more automated and resistant to link failures
D. Fast switchover from the RP tree to the shortest path tree

答案：A

解題說明：
Aruba CX with VSX supports enhanced multicast resiliency beyond standard PIM-SM by allowing active-active multicast forwarding and fast recovery if a VSX/core switch fails.

問題 #35
You are designing an L3 spine and leaf topology that uses CX switches. Those switches implement EVPN VXLAN with a distributed gateway model. You are helping implementers to assemble a list of required loopback interface IDs and IP blocks. What information do you need from the customer to complete this list?

A. For each overlay VRF, whether it will have DHCP servers to which relay is required
B. For each overlay VRF whether the customer requires L2 multicast forwarding
C. Whether the customer prefers OSPF or BGP as a routing protocol
D. Whether the customer prefers a single-AS or dual-AS design for the VXLAN control plane

答案：A

解題說明：
The choice of single-AS versus dual-AS affects the BGP control-plane configuration and AS numbering, not principally the required loopback inventory. Distributed-gateway designs can require dedicated per-VRF loopback addressing for services such as DHCP relay and unique source addressing. HPE also recommends planning an IP block for the loopbacks assigned to each overlay VRF.

問題 #36
You have been called in to help design an HPE Aruba Networking CX network solution to connect AI servers to file storage. The solution must support NFS over RDMA and provide 400 GbE links to the edge. The design currently consists of leaf and spine switches, which carry all traffic in VXLAN tunnels. Each switch is a CX 9300-32D switch. What is one correction that you should make to the design?

A. Continue to use CX 9300-32D switches for the spine but use CX 9300S switches as leaf switches to optimize costs
B. Redesign the solution to carry traffic without VXLAN to ensure support for DCB
C. Eliminate the spine to establish a rail-only topology
D. Replace the CX 9300-32D switches with CX 9300S switches to ensure support for RoCEv1/v2

答案：B

解題說明：
NFS over RDMA/RoCE requires lossless Ethernet behavior with DCB features such as PFC/ETS and ECN. For CX 9300-based RoCE designs, ECN is supported in the underlay, not in the VXLAN overlay, so RDMA storage traffic should not be carried through VXLAN tunnels.

問題 #37
During the proposal stage, the customer asks why you recommended VSX instead of a traditional stacking solution for their top-of-rack switches. What is the best justification?

A. VSX eliminates the need for redundant power supplies
B. VSX allows independent control planes on each switch, so a software issue on one switch does not affect the other, unlike stacking which shares a single control plane
C. VSX is only available on access switches
D. VSX requires fewer cables than any other design

答案：B

解題說明：
VSX (Virtual Switching Extension) keeps each switch's control plane independent, so a software fault or reboot on one member doesn't take down the entire redundant pair -- a key resiliency advantage over traditional stacking, which shares a single control plane across members.

問題 #38
You are brought in to a customer with 1,115 employees to update the network and the previous network manager has left the company. What are methods to validate the current network state when the available network documentation is not up-to-date? (Choose two.)

A. Physically examine the network devices and trace the cables from device to device documenting the connections and cabling type.
B. Use neighbor discovery protocols to learn neighbor relationships, document the connections and build a topology from the learned information.
C. Begin searching through file shares for old documentation and compare the files and drawings to each other.
D. Documenting existing network configuration and topology is not required. Previous iterations of network designs are considered obsolete and the best practice is that new designs are 'clean- sheet' designs.
E. Interview random company staff to gather the 'tribal knowledge' of how the network functions during normal operations and degraded states.

答案：A,B

解題說明：
When documentation is outdated, the current state should be validated by directly inspecting physical cabling/devices and by using neighbor discovery protocols such as LLDP/CDP to identify real device relationships and build an accurate topology.
