NSX-T Data Center Flashcards
What are the advantages provided by NSX-T Data Center?
NSX-T Data Center connects applications across private and public clouds, provides built-in security features, eliminates manual configuration, and provides a single access point to manage and monitor the network. It offers easier design, deployment, and management compared to traditional hardware-based solutions.
What is the role of NSX Manager in the NSX-T Data Center environment?
NSX Manager is the main component of NSX-T Data Center, performing both management and control plane functions. It provides a GUI and REST APIs for managing NSX-T components, like logical switches, routers, and firewalls. For high availability, it can be deployed as a three-instance cluster called an NSX Management cluster.
What is NSX Manager?
NSX Manager is the main component in the NSX-T Data Center environment, providing a GUI and REST APIs for configuring and monitoring NSX-T Data Center components. It’s deployed as a virtual machine and performs both management and control plane functions.
What is the role of hypervisors in NSX-T Data Center?
Hypervisors, such as ESXi and KVM, host workloads like VMs or containers in NSX-T Data Center. They are prepared by NSX Manager to carry NSX traffic, enabling them to host NSX virtual networks.
What are NSX Edge nodes?
NSX Edge nodes can be deployed as VMs or directly on bare-metal servers. They offer resources to create virtual routers and network services, such as NAT, VPN, and load balancing for the NSX environment. They can be grouped to form an NSX Edge cluster.
What are segment profiles in NSX-T Data Center?
Segment profiles in NSX-T Data Center contain layer 2 networking configuration details, which can be applied at a port level or segment level. They include settings for Quality of Service (QoS), IP Discovery, SpoofGuard, Switch Security, and MAC Management.
What is the function of an overlay transport zone in NSX-T Data Center?
An overlay transport zone in NSX-T Data Center is used for communication between transport nodes and carries Geneve-encapsulated traffic.
What is the function of a VLAN transport zone in NSX-T Data Center?
A VLAN transport zone in NSX-T Data Center is used to establish connectivity to external networks and carries VLAN or 802.1Q tagged traffic.
What is a transport zone in NSX-T Data Center?
A transport zone in NSX-T Data Center defines the scope of a segment or the reach of transport nodes. It belongs to either a VLAN or an overlay transport zone. The overlay zone is used for communication between transport nodes and carries Geneve-encapsulated traffic, while the VLAN zone establishes connectivity to external networks and carries VLAN or 802.1Q tagged traffic.
What is the function of an overlay transport zone in NSX-T Data Center?
An overlay transport zone in NSX-T Data Center is used for communication between transport nodes and carries Geneve-encapsulated traffic.
What is the function of a VLAN transport zone in NSX-T Data Center?
: A VLAN transport zone in NSX-T Data Center is used to establish connectivity to external networks and carries VLAN or 802.1Q tagged traffic.
What does NSX-T Data Center use for virtual network traffic encapsulation and transport?
SX-T Data Center uses Geneve tunneling to encapsulate virtual network traffic and carry it over the physical network via tunnels between tunnel endpoints (TEPs) on transport nodes.
What are the characteristics of Tier-0 gateways in NSX-T Data Center?
Tier-0 gateways connect virtual and physical networks, are hosted on NSX Edge nodes, support static and dynamic routing protocols (like BGP), and support equal-cost multipath (ECMP) routing for load balancing and fault tolerance. This traffic is also referred to as North-South traffic.
What are the characteristics of Tier-1 gateways in NSX-T Data Center?
Tier-1 gateways connect virtual machines and containers across different networks or segments (East-West traffic). They provide segment interconnection and separation, offer gateway services to internal networks, are distributed across all participating transport nodes, do not use dynamic routing protocols, and connect to a Tier-0 gateway for external connectivity.
What is the difference between a multitier and a single-tier deployment in NSX-T Data Center?
In a multitier deployment, segments connect to Tier-1 gateways, which connect to the Tier-0 gateway. This is used when different teams manage Tier-0 and Tier-1 gateways. In a single-tier deployment, segments directly connect to the Tier-0 gateway, without a Tier-1 gateway. This is used when the same team manages all gateways.
