VMware Advanced VMware Cloud Foundation 9.0 Networking 認定 3V0-25.25 試験問題 (Q12-Q17):質問 # 12
An administrator has a VMware Cloud Foundation (VCF) instance. A critical NSX security update has been released by Broadcom. How can the administrator install the NSX update?
正解：B
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In the unified architecture ofVMware Cloud Foundation (VCF) 9.0, the management paradigm has shifted towards a more centralized "Fleet Management" approach. Historically, in VCF 4.x and 5.x, updates were primarily managed via the SDDC Manager using the Lifecycle Management (LCM) engine. However, with the integration advancements in version 9.0,VCF Operations(formerly part of the Aria/vRealize suite) has taken on a more direct role in the orchestration of updates across the entire VCF "Fleet." To comply with the VCF operational model, administrators no longer apply patches directly within the component managers (like NSX Manager or vCenter) if they wish to remain within the supported, automated framework. Instead, the workflow begins by downloading the bundle or patch toVCF Operations. This ensures that the update is validated against the currentBill of Materials (BOM)and that all dependencies- such as compatibility with the underlying ESXi versions or the management vCenter-are checked before any changes are committed.
Once the patch is available in VCF Operations, the administrator utilizesFleet Managementto apply it. This service orchestrates the update across all NSX Managers and Transport Nodes (Edges and Hosts) in a controlled, non-disruptive manner. If the administrator were to apply the patch directly in NSX Manager (Option D), the SDDC Manager and VCF Operations databases would go out of sync, leading to a
"configuration drift" where the system no longer knows which version is actually running, potentially breaking future automated lifecycle tasks. Therefore, the centralized download and application throughVCF Operations Fleet Managementis the verified procedure for maintaining a healthy and compliant VCF 9.0 environment.

質問 # 13
An administrator has observed an NSX Local Manager (LM) outage at the secondary Site. However, the NSX Global Manager (GM) in secondary Site remains operational. What happens to data plane operations and policy enforcement at the secondary site?
正解：A
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
The architecture ofNSX Federationwithin a VCF Multi-Site design is built upon a separation of theControl Planeand theData Plane. This "decoupled" architecture ensures high availability and resiliency even when management components become unavailable.
In NSX Federation, theGlobal Manager (GM)handles the configuration of objects that span multiple locations, while theLocal Manager (LM)is responsible for pushing those configurations down to the local Transport Nodes (ESXi hosts and Edges) within its specific site. When a configuration is pushed, the Local Manager communicates with theCentral Control Plane (CCP)and subsequently theLocal Control Plane (LCP)on the hosts.
If an NSX Local Manager goes offline, the "Management Plane" for that site is lost. This means no new segments, routers, or firewall rules can be created or modified at that site. However, the existing configuration is already programmed into theData Plane(the kernels of the ESXi hosts and the DPDK process of the Edge nodes).
According to VMware's "NSX Multi-Location Design Guide," the data plane remains fully operational during a Management Plane outage. Existing VMs will continue to communicate, BGP sessions on the Edges will remain established, and Distributed Firewall (DFW) rules will continue to be enforced based on the last known good configuration state cached on the hosts. The data plane does not require constant heartbeats from the Local Manager to forward traffic. Therefore, operations continue normally "headless" until the LM is restored and can resume synchronization with the Global Manager and local hosts. Failover to a primary site (Option D) is only necessary if the actual data plane (hosts/storage) fails, not just the management components.

質問 # 14
An administrator must provide North/South connectivity for a VPC. The fabric exposes a distributed external VLAN across all ESX hosts. But, the only BGP peer to the core is on a VLAN only accessible on the Edge Cluster. Which design is required?
正解：C
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In aVMware Cloud Foundation (VCF)environment utilizing theVirtual Private Cloud (VPC)model, North
/South connectivity is managed by theTransit Gateway (TGW). The TGW acts as the bridge between the VPC-internal networks and the provider-level physical network.
The scenario presents a specific constraint: while an external VLAN exists across all hosts, the actual BGP peering point (the interface to the physical core routers) is restricted to theNSX Edge Cluster. In NSX terminology, when a gateway or service must be anchored to specific Edge Nodes to access physical network services-such as BGP peering, NAT, or stateful firewalls-it must be configured as aCentralizedcomponent.
ACentralized Transit Gateway(Option C) is instantiated on the Edge nodes. This allows the TGW to participate in the BGP session with the core routers on the VLAN that is only accessible to those Edges. The TGW then handles the routing for the VPC's internal segments. Traffic from the ESXi transport nodes (East- West) travels via the Geneve overlay to the Edge nodes, where it is then routed North-South by the Centralized TGW using the physical BGP peer.
Option A is incorrect because "distributed eBGP peering" would require every ESXi host to have peering capabilities, which contradicts the constraint. Option B involves EVPN, which is a significantly more complex and different architecture than what is required for standard VPC North/South access. Option D is an unnecessarily complex routing design that is not the standard VCF/VPC implementation pattern. Thus, the use of a Centralized Transit Gateway on the Edge cluster is the verified design requirement to bridge the gap between the overlay VPC and the localized BGP peering point.

質問 # 15
The administrator must configure Border Gateway Protocol (BGP) on the Tier-0 Gateway to establish neighbor relationships with upstream routers. Which two statements describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose two.)
正解：A、D
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In the architecture ofVMware Cloud Foundation (VCF)and its networking component, NSX, theTier-0 Gatewayserves as the critical demarcation point between the virtualized overlay network and the physical infrastructure. To facilitate this communication, BGP is the industry-standard protocol utilized.
BGP is fundamentally designed as anExterior Gateway Protocol (EGP). While it can be used internally (iBGP), its primary role in a VCF deployment is to exchange routing information between the SDDC and the physical Top-of-Rack (ToR) switches or core routers (eBGP). This allows the physical network to learn about the virtual subnets (overlay segments) and allows the virtual environment to receive a default route or specific external prefixes. This confirms that BGP is utilized as an EGP in these designs.
Furthermore, as global IP networking has evolved, the traditional 2-byte Autonomous System (AS) numbers (ranging from 1 to 65,535) were found to be insufficient for the number of organizations requiring them.
Modern NSX versions integrated into VCF 5.x and 9.0 fully support4-byte Autonomous System numbers (ranging from 1 to 4,294,967,295). This support is essential for service providers and large enterprises that have been assigned 4-byte ASNs by regional internet registries.
Option A is incorrect because EIGRP is a proprietary Cisco protocol and is not used by NSX. Option C describes OSPF (Open Shortest Path First), which uses "Areas," whereas BGP uses "Autonomous Systems." Therefore, the ability to act as an EGP and support for 4-byte ASNs are the verified characteristics of BGP within the VCF networking stack.

質問 # 16
An administrator is enabling IPv6-to-IPv4 communication for workloads hosted in an NSX environment. The workloads use IPv6-only addressing, but the external systems they must reach are IPv4-only. To provide this translation service, the administrator decides to configure NAT64. Which two following characteristics about NAT64 are true? (Choose two.)
正解：B、C
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
As organizations modernize their infrastructure withVCF 5.x and 9.0, IPv6 adoption becomes more prevalent.
NAT64is a critical transition technology that allows IPv6-only hosts to communicate with IPv4-only resources by translating the packet headers.
In NSX, NAT64 is astateful service. Stateful services in the NSX architecture require a centralized point of processing to maintain the session state table. Because of this requirement, any gateway (Tier-0 or Tier-1) providing NAT64 servicesmust be configured in Active-Standby high availability mode. In Active-Active mode, asymmetric return traffic could hit a different Edge node that does not have the session information, causing the translation to fail. This is a fundamental design constraint for stateful NAT in NSX.
Furthermore, VMware NSX documentation specifies that NAT64 is a flexible service that can be implemented at multiple tiers of the logical routing hierarchy. It issupported on both Tier-0 and Tier-1 gateways. The choice of where to place the NAT64 service depends on the design requirements: placing it on the Tier-1 gateway allows for tenant-specific translation and offloads the Tier-0, while placing it on the Tier-0 provides a centralized translation point for all connected segments.
Option A is incorrect because NAT64 in NSX is stateful, not stateless. Option C is incorrect because it is not limited to Tier-1. Option E is incorrect because Active-Active mode does not support the stateful nature of the NAT64 engine. Consequently, the correct architecture requires anActive-Standbyconfiguration on either a Tier-0 or Tier-1gateway to properly facilitate the translation between the IPv6 workloads and the IPv4 external world.
