Which two statements describe the recommended strategy for configuring and synchronizing security policies across Federated NSX sites? (Choose two.)

• A.Security policies, such as Distributed Firewall rules and security groups, must be defined as global policies on the Global Manager (GM).
• B.Consistency is achieved by ensuring all security groups have the exact same name on every Federated site's Local Manager (LM).
• C.Security policies should be defined locally on each LM and only synchronized manually by an administrator to prevent accidental conflicts.
• D.The Global Manager only synchronizes networking (L2/L3) configurations. Security rules must be configured separately on each site.
• E.Local Managers (LMs) can define local policies, but any global policies defined on the GM always take precedence over the local ones.

An administrator is configuring Border Gateway Protocol (BGP) routing on a Tier-0 Gateway to optimize north-south traffic flow between the NSX environment and multiple upstream physical routers. The environment includes two external connections that advertise overlapping routes to the same destination networks. To ensure predictable and efficient routing behavior, the administrator decides to manipulate specific BGP attributes on outbound advertisements and inbound route updates. What are two valid BGP Attributes that can be used to influence the route path traffic will take? (Choose two.)

• A.MED
• B.AS-Path Prepend
• C.Cost
• D.BFD

An administrator needs to prevent the datacenter from advertising any internal prefixes toward a new VPC, while still ensuring the VPC receives a default route learned from the datacenter's upstream network. Where should the routing policy be applied?

• A.On the provider Tier-0 neighbor.
• B.On each segment default gateway.
• C.On the Tier-1 gateway.
• D.On the VPC transit gateway.

An administrator has a standalone vSphere 8.0 Update 1a deployment that is running with VMware NSX
4.1.0.2 and has to converge the deployment into a new VMware Cloud Foundation (VCF) instance. How can the administrator accomplish this task?

• A.Manually upgrade both vSphere and NSX to version 9 prior to converging. Then use the VCF Installer to converge the vSphere 9 and NSX 9 instances into a new VCF management domain.
• B.Use the VCF Installer to converge the existing vSphere 8 and NSX 4 environment into a new VCF management domain. Then use the VCF lifecycle management tools to upgrade to 9.
• C.Manually upgrade vSphere to version 9. Then use the VCF Installer to converge the vSphere 9 environment into a new VCF management domain. Then use the VCF lifecycle management tools to upgrade NSX to version 9.
• D.Manually upgrade vSphere to version 9 and uninstall NSX 4. Then use the VCF Installer to converge the vSphere 9.0 environment into a new VCF management domain at which time NSX 9 will be reinstalled.

An administrator was asked to explain the characteristic and requirements of Centralized Connectivity Mode which is planned to be configured in one of the workload domains in VMware Cloud Foundation (VCF) environment.
Drag and drop four options from the Options list on the left and place them into the Centralized Connectivity Mode on the right in any order. (Choose four.)

정답:

Explanation:
* Requires the deployment of an NSX Edge cluster to host the Tier-0 gateway.
* It can be configured during the deployment of the workload domain.
* It supports stateful services configuration.
* It is suitable for environments that require a streamlined network with limited NSX networking services.
InVMware Cloud Foundation (VCF) 9.0, the networking architecture introduces specialized connectivity modes to cater to different organizational needs, withCentralized Connectivity Modebeing a primary option for streamlined deployments. This mode is fundamentally anchored to the physical infrastructure via localized resources rather than distributed components across the entire cluster.
The most critical technical requirement for this mode is that itrequires the deployment of an NSX Edge cluster to host the Tier-0 gateway. Unlike distributed models, centralized connectivity funnels North-South traffic through specific Edge nodes that serve as the demarcation point between the virtual overlay and the physical Top-of-Rack (ToR) switches. This centralization is what enables the next key characteristic: it supports stateful services configuration. Because traffic is anchored to specific Service Routers (SR) on Edge nodes, stateful operations such as NAT, Load Balancing, and stateful firewalls can maintain session persistence, which is not natively possible in a purely distributed Active/Active ECMP environment without specialized configuration.
From a lifecycle perspective, this mode is highly integrated into the SDDC Manager workflows andcan be configured during the deployment of the workload domain. This allows architects to define the networking posture of a new domain at "Day 0," ensuring that the necessary Edge resources and Tier-0/Tier-1 hierarchies are provisioned automatically to meet the domain's specific requirements.
Finally, Centralized Connectivity Modeis suitable for environments that require a streamlined network with limited NSX networking services. It provides a "cloud-lite" approach to networking, offering the necessary isolation and security of NSX without the complexity of managing a full-scale distributed fabric.
This makes it an ideal choice for smaller workload domains, specialized labs, or legacy application environments that do not require the massive scale of a distributed transit gateway but still need robust stateful security and simplified North-South egress.
