VMware Advanced VMware Cloud Foundation 9.0 Networking 認定 3V0-25.25 試験問題 (Q37-Q42):質問 # 37
How should the Global Managers (GMs) and Local Managers (LMs) be distributed to ensure high availability and optimal performance in a multi-site NSX Federation deployment comprised of three sites? (Choose two.)
正解：B、D
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In aVMware Cloud Foundation (VCF)Federation deployment across multiple sites, the management architecture is designed to provide "Global Visibility" while maintaining "Local Autonomy." This is achieved through the coordinated distribution ofGlobal Managers (GMs)andLocal Managers (LMs).
For a three-site deployment,NSX Federationbest practices mandate that each site maintains its ownLocal Manager (LM) Cluster(Option A). The LM is responsible for the site-specific control plane, communicating with local Transport Nodes (ESXi and Edges) to program the data plane. If the connection to the GM is lost, the LM ensures the local site continues to function normally. For production environments, these must be clusters (typically 3 nodes) rather than single nodes to ensure local management remains available.
To protect theGlobal Manageritself-which is the source of truth for all global networking and security policies-the GM cluster should bestretched across the three sites(Option D). In a standard 3-node GM cluster, placing one node at each site ensures that the Federation management plane can survive the complete failure of an entire site. This "stretched" cluster configuration provides a high level of resilience and ensures that an administrator can still manage global policies from any surviving location.
Option B is incorrect because the GM does not communicate directly with the data plane of a site; it must go through an LM. Option C is a risk to availability. Option E is incorrect because vSphere HA cannot protect against a site-wide disaster, and a single appliance represents a significant single point of failure for the entire global network configuration.

質問 # 38
An administrator is upgrading an existing VMware Cloud Foundation (VCF) environment. An NSX Edge Cluster is required to support north-south traffic for a workload domain. How would the administrator initiate the edge cluster deployment?
正解：D
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In the architectural framework ofVMware Cloud Foundation (VCF) 9.0, the deployment and lifecycle management of infrastructure components have transitioned into a unified "Fleet Management" model. While previous versions of VCF (like 4.x or 5.x) relied exclusively on the SDDC Manager UI for the deployment of NSX Edge Clusters, VCF 9.0 centralizes these operations withinVCF Operations(integrated with the functionality formerly known as Aria Operations).
To initiate the deployment of an NSX Edge Cluster for a workload domain, the administrator uses theVCF Operations Fleet Manager. This interface provides a centralized orchestration point for the entire VCF
"fleet." When the deployment is triggered here, the system automates the selection of the underlying ESXi hosts, the configuration of the Virtual Distributed Switch (VDS) trunks, and the instantiation of the Edge VM appliances. This ensures that the deployment adheres strictly to theVMware Validated Solutions (VVS) guidelines and is consistent across all domains.
Option A is incorrect because theVCF Installer(Cloud Builder) is used for the initial "Day 0" bring-up of the Management Domain, not for post-deployment additions to workload domains. Option C and D are incorrect asvCenterand theVAMIdo not possess the multi-component awareness or the SDDC-level automation required to configure NSX Edge Clusters in a VCF context. By usingFleet Manager, VCF ensures that the new Edge cluster is automatically integrated into the SDDC Manager's inventory and lifecycle management workflows, maintaining a "single source of truth" for the entire private cloud environment.

質問 # 39
Which two statements describe the recommended strategy for configuring and synchronizing security policies across Federated NSX sites? (Choose two.)
正解：A、E
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
NSX Federationis the cornerstone of multi-siteVMware Cloud Foundation (VCF)security, enabling administrators to maintain a consistent security posture across geographically dispersed data centers. The management of security in a Federated environment relies on a hierarchical relationship between theGlobal Manager (GM)andLocal Managers (LMs).
According to VMware documentation, the recommended strategy is to defineGlobal Security Policieson the Global Manager (Option B). When a security group or a Distributed Firewall (DFW) rule is created on the GM, it is automatically synchronized to all registered Local Managers. This ensures that a "Finance App" security policy is identical in AZ1 and AZ2. These global objects are identified by a specific tag in the local NSX Manager UI, indicating they are managed globally and cannot be modified locally.
Furthermore, NSX handles the coexistence of global and local rules through a specific evaluation order (Option D). In the NSX DFW category structure,Global Categories(managed by the GM) are evaluated beforeLocal Categories(managed by the LM). This ensures that corporate-wide security mandates (like
"Block All SSH to Management") defined at the GM level are enforced first and cannot be bypassed by localized site-level rules.
Option A is incorrect because manual naming consistency is prone to error and does not provide actual synchronization. Option C and E are incorrect as they contradict the fundamental purpose of Federation, which is to centralize management and automate synchronization to prevent configuration drift and security gaps. Therefore, defining policies on the GM and utilizing the inherent precedence of global rules is the verified design best practice for VCF Federation.

質問 # 40
When using a DHCP Relay on a segment, which design restriction must be considered?
正解：B
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
InVMware Cloud Foundation (VCF)networking, IP address management within an NSX segment can be handled by either the native NSX DHCP server or by an external DHCP server. When an administrator chooses to use an existing external corporate DHCP infrastructure, they must configure aDHCP Relayon the logical segment.
The DHCP Relay works by intercepting the initial DHCP Discover broadcast from a workload VM and forwarding it (as a unicast packet) to the specified IP address of the external DHCP server. However, NSX enforces a strict mutual exclusivity in its configuration logic to prevent conflicts and unpredictable address assignments.
According to the "NSX-T Data Center Administration Guide," once a segment is configured to use aDHCP Relay profile, the native NSX DHCP capabilities for that specific segment are disabled. This means that DHCP settings, DHCP options, and static bindings cannot be configured on that segment(Option A). All such configurations, including IP reservations and scope options (like DNS or NTP), must be managed centrally on the external DHCP server.
Option C is incorrect because the UI will physically grey out or prevent the entry of native DHCP parameters once the Relay is selected. Option B is incorrect as the primary purpose of a Relay is precisely to forward requests to external servers. Option D is incorrect because a DHCP Relay is configured on a per-segment or per-gateway basis; it is not a "global" service that automatically covers all other segments in the network.
Therefore, the architectural trade-off when choosing a Relay is the shift of all management and binding logic to the external physical or virtual DHCP appliance.

質問 # 41
An administrator is troubleshooting BGP flapping in a VMware Cloud Foundation (VCF) 9 environment. A Tier-0 Gateway is running in Active/Active mode with two Edge nodes. BFD is enabled on the eBGP sessions to the upstream routers. Each Edge node uses its own uplink IP for BGP. After some network maintenance, one BGP session starts flapping every few minutes. The other BGP sessions stay stable. On the affected Edge node, the command get bfd-sessions shows:
* State: Down
* Diag: Detect Time Expired
Symptoms:
* The upstream router also shows the BFD session as Down with control Detection Time Expired.
* There are no interface errors, no packet loss for normal traffic, and clearing the BFD session temporarily brings it back up - but it flaps again after few minutes.
What is the root cause?
正解：B
解説：
Comprehensive and Detailed 250 to 350 words of Explanation From VMware Cloud Foundation (VCF) documents:
In aVMware Cloud Foundation (VCF)environment, particularly with the high-performance requirements of North-South routing,BGPandBFD (Bidirectional Forwarding Detection)are used in tandem to ensure rapid failure detection. A common but subtle issue in fresh or modified environments is anMTU (Maximum Transmission Unit) mismatchon the physical or virtual uplinks.
When BGP establishes a neighborship, it initially exchanges small keepalive packets. These small packets easily pass through interfaces even if there is an MTU mismatch (e.g., the Edge is set to 9000 bytes but a physical switch in the path is limited to 1500 bytes). However, once the BGP state reaches "Established," the routers begin exchanging full routing tables. TheseBGP Updatepackets are often large and will be fragmented or dropped if they exceed the MTU of any hop in the path.
The symptom described-where the session is stable for a few minutes (during the initial handshake) and then flaps-is the hallmark of an MTU issue. The "Detect Time Expired" diagnostic in BFD occurs because the BGP hold timer expires when it fails to receive the large update packets, or the BFD packets themselves are delayed/lost due to the congestion caused by retrying large, failed transmissions. According to VMware NSX troubleshooting documentation, if pings (small packets) succeed but the BGP session fails specifically when traffic load or route counts increase, the MTU should be the first setting verified.
VCF 9.0 and 5.x designs mandate consistent MTU settings (typically9000 MTUfor the overlay and at least
1500+for the uplinks) across the entire path, including the virtual switch (VDS), the Edge VM vNICs, and the physical ToR switches. A mismatch here prevents the completion of the BGP state machine's full synchronization, leading to the cyclic "flapping" observed by the administrator.
