Upgrade to PremiumA Solutions Architect has been tasked with designing a comprehensive security policy methodology for a large financial institution. The institution has multiple departments and requires strict segregation of network traffic to ensure data confidentiality and regulatory compliance. The security policy should provide granular control over network traffic and enforce consistent security measures across the entire infrastructure.
Which feature of the NSX security policy should the architect recommend to achieve regulatory compliance for the financial institution?
Correct : C
Micro-Segmentation for Granular Security (Correct Answer - C):
Micro-segmentation in NSX-T enables granular firewall policies at the workload level, ensuring strict segregation of traffic across different departments.
It allows zero trust security, ensuring only authorized communications occur between workloads, reducing attack surfaces.
This is particularly critical for financial institutions that need regulatory compliance (e.g., PCI-DSS, GDPR, ISO 27001).
Incorrect Options:
(A - Intrusion Detection & Prevention - IDS/IPS):
IDS/IPS provides threat detection, but it does not segment workloads or enforce access control.
(B - Identity-Based Firewalling):
NSX Identity Firewall (IDFW) can be useful for user-based policies but is not a replacement for network segmentation.
(D - Network Introspection):
NSX Network Introspection is used for third-party security integrations, not as a primary segmentation strategy.

A company is planning to deploy NSX to provide a multi-tenant environment for their customers. The solutions architect is responsible for designing the network services to ensure that each tenant's traffic is isolated and secure.
Which of the following NSX features should the solutions architect use to achieve this goal?
Correct : D
Distributed Firewall for Multi-Tenant Security (Correct Answer - D):
NSX Distributed Firewall (DFW) enables tenant isolation at the virtual machine level.
It enforces security policies directly on vNICs, ensuring East-West traffic control without needing hardware firewalls.
This ensures multi-tenancy compliance, preventing cross-tenant communication unless explicitly allowed.
Incorrect Options:
(A - Load Balancing):
NSX Load Balancer improves application availability but does not provide traffic isolation.
(B - VLAN):
VLANs provide basic segmentation but do not offer granular control like DFW.
(C - NAT):
NAT provides IP address translation but does not ensure tenant security.

Which three VMware guidelines are recommended when designing VLANs and subnets for a single region and single availability zone? (Choose three.)
Correct : A, D, E
Recommended Network Design Guidelines:
(A - Use RFC1918 Addressing):
VMware NSX-T recommends using RFC1918 private address space for internal networks to avoid public address conflicts.
(D - Use /24 Subnets):
/24 subnets are preferred as they provide 256 usable IPs, simplifying management and subnetting.
(E - Floating Interface for VRRP/HSRP):
NSX Gateway HA uses VRRP (Virtual Router Redundancy Protocol) or HSRP (Hot Standby Routing Protocol) for gateway failover, ensuring redundancy.
Incorrect Options:
(B - Use IPv6 RFC2460 Addressing) IPv6 is optional in NSX, but IPv4 remains the primary addressing method.
(C - Use /16 Subnets) Using /16 subnets results in large broadcast domains and unnecessary complexity.

A large multinational company is expanding its data center due to increased demand for online services.
The company is considering shifting from an NSX Edge VM design to a bare-metal NSX Edge design to accommodate new hardware acquisitions and maximize performance.
Which is a potential benefit for the company in shifting from an NSX Edge VM design to a bare-metal NSX Edge design?
Correct : A
Performance Benefits of Bare-Metal NSX Edge (Correct Answer - A):
Bare-metal NSX Edge Nodes provide higher performance by eliminating the virtualization overhead associated with Edge VMs running inside ESXi/KVM hosts.
This increases throughput and reduces latency, making it ideal for high-bandwidth applications (e.g., Load Balancing, VPN, and NAT).
Incorrect Options:
(B - More VLANs):
The number of VLANs is not limited by the NSX Edge type. VLAN scalability depends on physical network design.
(C - Automatic Stateful Service Distribution):
Stateful services (NAT, FW, LB, VPN) do not auto-distribute. Stateful HA must be manually configured.
(D - Eliminates Stateful Services):
Stateful services (e.g., NAT, Load Balancer, Firewall) are still required, regardless of Edge deployment mode.

What are the design considerations for segment and transport zone design?
Correct : D
NSX-T Segment and Transport Zone Design Considerations (Correct Answer - D):
Network topology influences how segments and transport zones are structured.
Availability ensures failover and redundancy are properly planned in transport zones.
Scalability is crucial when designing segments to accommodate growth without redesign.
Incorrect Options:
(A - Server hardware, OS, and application requirements):
These impact workload performance but are not primary factors in transport zone design.
(B - VLAN design, subnet design, and routing design):
These are part of traditional network design, but NSX-T segments use overlay networks instead.
(C - Number of VMs, network performance, and security):
While relevant, these factors alone do not define transport zone and segment architecture.
