VMware NSX 4.x Advanced Design Sample Questions (Q114-Q119):

NEW QUESTION # 114
A global media organization is planning to deploy VMware NSX to manage their network infrastructure. The organization needs a unified networking and security platform that can handle their geographically dispersed data centers while providing high availability, seamless workload mobility, and efficient disaster recovery. A Solutions Architect is tasked with designing a multi-location NSX deployment that addresses requirements.
Given the organization's needs, how should the Solutions Architect design the multi-location NSX deployment?

A. Deploy NSX Federation to manage local NSX Managers in each location.
B. Deploy NSX independently in each location and manage each location separately.
C. Deploy NSX in a single location and use VPNs to connect the other locations to the primary site.

Answer: A

Explanation:
1. Why NSX Federation is the Right Solution (Correct Answer - C)
* NSX Federation allows centralized management of multiple NSX environments across locations.
* Enables seamless workload mobility and security policy enforcement across data centers.
* Supports disaster recovery by ensuring consistent network and security policies are applied globally.
* Key Benefits Include:
* Global Security and Networking Policy Management.
* Centralized Administration for all NSX deployments.
* Automated failover and disaster recovery across sites.
2. Why Other Options are Incorrect
* (A - VPNs Only):
* VPNs alone do not provide unified management; they onlysecure site-to-site communication.
* (B - Independent NSX Instances):
* Managing separate NSX instances per site is complex and does not support global policy synchronization.
3. Key Considerations for NSX Federation Deployment
* Each NSX site must be running the same NSX version and build.
* A Global Manager (GM) is required for centralized management.
* Inter-site connectivity must support high-performance and low-latency communication for real- time policy enforcement.

NEW QUESTION # 115
When designing top-of-rack (ToR) switches, which guideline is crucial?

A. Using a single switch for multiple racks when possible
B. Minimizing the number of switch ports
C. Ensuring redundancy and high availability
D. Prioritizing low-cost equipment

Answer: C

NEW QUESTION # 116
Which three VMware guidelines are recommended when designing VLANs and subnets for a single region and single availability zone?(Choose three.)

A. Use the RFC1918 IPv4 address space for these subnets and allocate one octet by region and another octet by function.
B. Use the IP address of the floating interface for Virtual Router Redundancy Protocol (VRRP) or Hot Standby Routing Protocol (HSRP) as the gateway.
C. Use only /24 subnets to reduce confusion and mistakes when handling IPv4 subnetting.
D. Use only /16 subnets to reduce confusion and mistakes when handling IPv4 subnetting.
E. Use the RFC2460 IPv6 address space for these subnets and allocate one set by region and another set by function.

Answer: A,B,C

Explanation:
* RFC1918 Address Space (A)
* VMwarerecommends using private IPv4 address rangesfromRFC1918. This ensures internal network segmentation without public exposure.
* Allocatingone octet for region and another for functionhelps with structured IP management.
* Subnet Sizing (D)
* Using /24 subnetsis preferred inNSX-T designbecause:
* Itsimplifies managementby offering256 usable IP addresses per subnet.
* It preventsoverlapping IP issuesand ensuresbetter compatibility with firewalls and routers.
* Floating Interface for VRRP/HSRP (E)
* NSX-T supportsredundant gatewaysusingVRRP (Virtual Router Redundancy Protocol)or HSRP (Hot Standby Routing Protocol).
* Thefloating IPacts as aredundant gateway, ensuringseamless failoverinmulti-gateway environments.
* Incorrect Options:
* (B - IPv6 RFC2460)# NSX primarily usesIPv4for most enterprise deployments. IPv6 support is limited and requires additional configuration.
* (C - /16 Subnets)# Using/16 subnetsis impractical for micro-segmentation as it createslarger broadcast domainsand increasesnetwork overhead.

* NSX-T Best Practices for VLAN and Subnet Design

NEW QUESTION # 117
Which of the following describes the role of the NSX Gateway Firewall as an inter-tenantfirewall within a VMware NSX solution?

A. It secures communication between on-premises physical servers and virtual machines (VMs) in the cloud.
B. It controls access to virtual resources based on user identity and authentication.
C. It inspects and filters traffic between virtual machines (VMs) within the same tenant.
D. It isolates different tenants' virtual networks, preventing unauthorized communication between them.

Answer: D

Explanation:
* NSX Gateway Firewall for Multi-Tenancy (Correct Answer - C):
* The NSX Gateway Firewall acts as an inter-tenant firewallbyisolating different tenants' networksto preventcross-tenant communication.
* Ensuresmulti-tenancy security,per-tenant policy enforcement, andNorth-South traffic control
.
* Incorrect Options:
* (A - Secures On-Prem to Cloud Communication):
* This is handled byIPSec VPN, BGP, or NAT, not theGateway Firewall.
* (B - Filters Intra-Tenant Traffic):
* Intra-tenant filteringis the responsibility of theNSX Distributed Firewall (DFW), not the Gateway Firewall.
* (D - User-Based Access Control):
* Identity-Based Firewall (IDFW)controls access based on user authentication, notnetwork segmentation.

NEW QUESTION # 118
Which factors should be considered for NSX Manager sizing? (Choose two)

D. The personal preferences of network administrators

Answer: A,C
