NEW QUESTION # 40
To prepare for a data center network implementation, you have asked a customer for a list of VLANs to support. The customers list for several VMware ESXi hosts includes 4095. What follow up question should you ask?
Answer: A
Explanation:
In VMware ESXi, VLAN ID 4095 on a port group means VLAN trunking/VGT, allowing guest VMs to tag traffic themselves. You need to identify the actual VLAN tags used by those VMs.
NEW QUESTION # 41
A customer's security team requires micro-segmentation down to the individual workload level within the data center. Which technology combination best satisfies this requirement in an Aruba CX + VMware environment?
Answer: A
Explanation:
NSX's distributed firewall enforces security policy at the vNIC/workload level regardless of physical topology, while the CX VXLAN/EVPN fabric provides the underlying transport. VLANs alone can't achieve workload-level granularity, physical firewalls per server pair are impractical, and disabling east-west traffic breaks application functionality.
NEW QUESTION # 42
Which two are valid reasons to recommend a routed underlay (Layer 3 to the leaf) in a VXLAN/EVPN fabric design? (Choose two.)
Answer: D,E
Explanation:
A routed underlay removes STP dependency and enables ECMP across all spine-leaf paths for deterministic load balancing and fast convergence. It still requires underlay IP addressing, doesn't guarantee zero oversubscription (that's a hardware/design choice), and doesn't eliminate the need for an overlay if one is desired for mobility/segmentation.
NEW QUESTION # 43
In multi-fabric design, what is the minimal recommended MTU?
Answer: C
Explanation:
Multi-fabric EVPN/VXLAN designs require jumbo MTU for encapsulation overhead, and HPE Aruba validated configurations commonly use MTU 9198 on AOS-CX links/interfaces.
NEW QUESTION # 44
A customer is upgrading their data center structured cabling to SMF. At the same time the customer wants to upgrade the spine switches in their spine and leaf topology A key goal of this upgrade is to eventually support 400GbE leaf-to-spine links. However, for a while, many of the leaf switches will continue to support 100GbE uplinks. What is a valid recommendation for the spine switches?
Answer: B
Explanation:
The CX 9300-32D is appropriate as a 100/400GbE spine and supports breakout use cases, while
4x100G DR QSFP-DD supports SMF and lets the spine connect to current 100GbE leaves during migration to 400GbE.
