VMware 3V0-25.25 問題集 練習問題・模擬試験｜日本語版＆英語版対応

サンプル問題 1： An NSX Administrator is creating a Transport Node Profile and needs to define how the TEP IP Addresses are assigned to the hosts in the cluster. Which method allows the use of a list of pre-defined IP addresses managed by NSX, without requiring a DHCP server on the TEP VLAN?

• A: Select "Static IP List" and paste a CSV file containing the IPs directly into the Transport Node Profile wizard.
• B: In the Transport Node Profile configuration, choose "Autoconfigure" to use IPv6 SLAAC (Stateless Address Autoconfiguration) for TEP IP addresses.
• C: Select "IPv4 IP Pool" and assign a pre-created IP Pool object (with subnet and IPs) to the profile.
• D: Select the "Use Management IP" option in the Transport Node Profile to set the TEP IP address equal to the host's management IP address.

サンプル問題 2： An Infrastructure Auditor is reviewing the CPU reservation policies applied to a cluster of "Large" form factor NSX Edge VMs in a VCF environment. The environment is heavily oversubscribed (3:1 vCPU to pCPU ratio). The Transport Node Profile for the Edge cluster shows the following: [NSX Edge VM Profile] Form Factor: Large (8 vCPU / 32 GB RAM) Datapath CPU Configuration: 2 Management / 6 Datapath (Fastpath) vSphere CPU Reservation: 0 MHz (None) Latency Sensitivity: Normal Which TWO statements represent anti-patterns in this design that will severely degrade the NSX data plane performance? (Choose 2.)

• A: The NSX Edge software automatically detects high CPU contention levels and dynamically shifts datapath processing back to the physical ToR switches to maintain throughput.
• B: NSX Edge VMs require 100% CPU reservation to prevent the ESXi scheduler from stalling the DPDK polling threads used for datapath processing.
• C: Compute contention in the oversubscribed environment causes management CPU starvation, leading to BGP timer timeouts and Edge node drops.
• D: Edge VMs should be redeployed using the "Medium" form factor in oversubscribed environments to significantly reduce hypervisor CPU ready time and resource contention.
• E: While 3:1 oversubscription is acceptable for management vCPUs, the datapath vCPUs must be configured with Hyper-Threading disabled inside the VM guest OS to ensure stability.

サンプル問題 3： 2 5.2 87.9 0.3 dp-core-worker-1 nsx-edge-01> get system performance Datapath CPU Usage: HIGH (Avg 86%) RX Ring Buffer: Full (Drops Detected) TX Ring Buffer: Normal Host CPU Ready (%RDY): 4.5% What is the primary contributor to these performance issues based on the data?

• A: High "Host CPU Ready" values indicate the underlying ESXi host is overcommitted, preventing efficient scheduling of Edge vCPUs.
• B: The "RX Ring Buffer" drops are symptomatic of a physical layer issue, specifically a faulty cable on the upstream Top-of-Rack switch.
• C: The Edge Node is undersized for the traffic load, and enabling "Standby Relocation" is required to resolve the CPU contention.
• D: The "dp-core-worker" utilization is normal, but the "TX Ring Buffer" is too large, which is causing significant buffer bloat latency.
