NSX Service Mesh provides a language-independent way to observe, automate, secure, and control microservices. It extends the capabilities of NSX-T Data Center to microservices, offering consistent networking and security across different environments. This allows customers to manage and secure their microservices without being dependent on the programming languages used to build those services.

B. It is a module deployed in all transport nodes that provides L2 functionality. D. ESXi hosts support both N-VDS and VDS.

N-VDS (NSX Virtual Distributed Switch) and VDS (vSphere Distributed Switch) are both network switch constructs used in NSX-T Data Center. The N-VDS provides Layer 2 (L2) functionality and is deployed on all transport nodes to handle network traffic. ESXi hosts support both N-VDS and VDS, allowing for flexible network configurations.

NSX-T Data Center supports BGP (Border Gateway Protocol) as a dynamic routing protocol. BGP is used for the exchange of routing information between different networks and is essential for enabling dynamic routing in large-scale environments.

A Software Defined Networking (SDN) solution has the following characteristics:

A. It allows workloads to be placed and migrated anywhere in the network: SDN abstracts the networking layer, enabling dynamic and flexible placement of workloads across the network without being tied to physical network constraints.

C. It is decoupled from the physical networking infrastructure: SDN separates the control plane from the data plane, allowing network management to be done via software, independent of the underlying physical hardware.

To create GENEVE backed segments using NSX-T Data Center, a customer needs to configure an Overlay Transport Zone. GENEVE is used as the encapsulation protocol for overlay networking in NSX-T, allowing the creation of logical network segments overlaid on top of the physical network.

The three types of transport nodes in NSX-T are:

A. NSX Edges: These are nodes that provide edge services and north-south routing.

D. Bare-metal servers: These servers can be configured as transport nodes to extend NSX-T networking and security to physical workloads.

F. Hypervisors: These nodes run virtualized workloads and host NSX-T virtual switches, enabling NSX-T to manage network traffic within the virtual environment.

The software-defined data center (SDDC) helps build the following solutions:

D. Hybrid cloud: SDDC provides the ability to integrate on-premises infrastructure with public cloud services, creating a seamless hybrid environment.

E. On-premises: SDDC principles can be applied within a private data center, allowing for automation, flexibility, and improved resource utilization.

F. Public cloud: SDDC technologies are also applicable to public cloud environments, enabling consistent infrastructure and operations across on-premises and cloud deployments.

The Distributed Resource Scheduler (DRS) can help solve the problem of virtual machines not getting required resources while some hosts in the cluster are underutilized. DRS balances the load across the hosts in a cluster by moving virtual machines to ensure optimal distribution of resources. It continuously monitors the cluster and makes adjustments to achieve better performance and resource utilization.

To encrypt file transfers between two sites that do not have the same subnet, the IPSEC VPN feature in NSX-T can be used. IPSEC VPNs provide secure communication over IP networks by encrypting the data transferred between the two sites, ensuring data confidentiality and integrity.

The firewall rule shown in the exhibit is part of a gateway firewall applied to a Tier-0 gateway (TO-GW-01). The key indicators are the "Category: LOCAL GATEWAY" and the "Applied to: TO-GW-01". The rule is set to "Drop" SSH traffic (port 22) from any source to the destinations listed (App-Servers, DB-Servers, Web-Servers).
