In VMware Cloud Foundation (VCF) 5.2, the logical design outlines high-level architectural decisions that define the system’s structure and behavior, distinct from physical or operational details, as per theVCF 5.2 Design Guide. Networking decisions in the logical design focus on connectivity frameworks, security policies, and scalability. Let’s evaluate each:

Option A: DD04 - Deploy 2x 64-port Cisco Nexus 9300 switches for top-of-rack ESXi host connectivityThis specifies physical hardware (switch model, port count), which belongs in the physical design (e.g., BOM, rack layout). TheVCF 5.2 Architectural Guideclassifies hardware selections as physical, not logical, unless they dictate architecture, which isn’t the case here.

Option B: DD01 - Set NSX Distributed Firewall (DFW) to block all traffic by defaultThis is a specific security policy within NSX DFW, defining traffic behavior. While critical, it’s an implementation detail (e.g., rule configuration), not a high-level logical design decision. TheVCF 5.2 Networking Guideplaces DFW rules in detailed design, not the logical overview.

Option C: DD03 - Connect the management interface eth0 of each NSX Edge node to VLAN 100This details a specific interface-to-VLAN mapping, an operational or physical configuration. TheVCF 5.2 Networking Guidetreats such specifics as implementation-level decisions, not logical design elements.

Option D: DD02 - Use VLANs to separate physical network functionsUsing VLANs to segment network functions (e.g., management, vMotion, vSAN) is a foundational networking architecture decision in VCF. It defines the logical separation of traffic types, enhancing security and scalability. TheVCF 5.2 Architectural Guideincludes VLAN segmentation as a core logical design component, aligning with standard VCF networking practices.

Conclusion:Option D (DD02) is included in the logical design, as it defines the architectural approach to network segmentation, a key logical networking decision in VCF 5.2.References:

The database cluster in a VCF 5.2 VI Workload Domain uses an all-flash vSAN Original Storage Architecture (OSA) cluster with a 40/60 read/write ratio, high IOPS needs, and no contention (implying sufficient resources). vSAN configuration impacts performance, especially for databases. Let’s evaluate:

Option A: Flash Read Cache ReservationIn all-flash vSAN OSA, the cache tier (flash) serves writes, not reads, which are handled by the capacity tier (also flash). ThevSAN Planning and Deployment Guidenotes that Flash Read Cache Reservation is deprecated for all-flash configurations, as reads don’t benefit from caching, making this irrelevant for performance here.

Option B: RAID 1RAID 1 (mirroring) replicates data across hosts, offering high performance and availability (FTT=1). For a 40/60 read/write workload with high IOPS, RAID 1 minimizes latency and maximizes throughput compared to erasure coding (e.g., RAID 5), as it avoids parity calculations. TheVCF 5.2 Architectural Guiderecommends RAID 1 for performance-critical workloads like databases, especially with no contention.

Option C: Deduplication and Compression disabledDisabling deduplication and compression avoids CPU overhead and latency from data processing, critical for high-IOPS workloads. ThevSAN Administration Guideadvises disabling these for performance-sensitive applications (e.g., databases), as the 60% write ratio benefits from direct I/O over space efficiency, given no contention.

Option D: Deduplication and Compression enabledEnabling deduplication and compression reduces storage use but increases latency and CPU load, degrading performance for high-IOPS workloads. ThevSAN Planning and Deployment Guidenotes this trade-off, making it unsuitable here.

Option E: RAID 5RAID 5 (erasure coding) uses parity, reducing write performance due to calculations, which conflicts with the 60% write ratio and high IOPS needs. TheVCF 5.2 Architectural Guiderecommends RAID 5 for capacity optimization, not performance, favoring RAID 1 instead.

Conclusion:

B: RAID 1 ensures high performance for IOPS and write-heavy workloads.

C: Disabling deduplication and compression optimizes I/O performance.These align with vSAN best practices for all-flash database clusters in VCF 5.2.References:

In VCF 5.2, the logical design focuses on high-level architectural decisions that define the system’s structure and behavior, as opposed to physical or operational details. Networking decisions in the logical design emphasize scalability, security policies, and connectivity frameworks, per theVCF 5.2 Architectural Guide. Let’s evaluate each:

Option A: Use of 2x 64-port Cisco Nexus 9300 for top-of-rack ESXi host switchesThis specifies physical hardware, a detail typically documented in the physical design (e.g., BOM, rack layout). TheVCF 5.2 Design Guidedistinguishes hardware choices as physical, not logical, unless they dictate architecture (e.g., spine-leaf), which isn’t implied here.

Option B: NSX Distributed Firewall (DFW) rule to block all traffic by defaultThis is a security policy configuration within NSX, defining how traffic is controlled. While critical, it’s an operational or detailed design decision (e.g., rule set), not a high-level logical design element. TheVCF 5.2 Networking Guideplaces DFW rules in implementation details, not the logical overview.

Option C: Implement overlay network technology to scale across data centersOverlay networking (e.g., NSX VXLAN or Geneve) is a foundational architectural decision in VCF, enabling scalability, multi-site connectivity, and logical separation of networks. TheVCF 5.2 Architectural Guidehighlights overlays as a core logical design component, directly impacting how the solution scales across data centers, making it a prime candidate for the logical design.

Option D: Configure Cisco Discovery Protocol (CDP) - Listen mode on all Distributed Virtual Switches (DVS)CDP in Listen mode aids network discovery and troubleshooting on DVS. This is a configuration setting, not a logical design decision. TheVCF 5.2 Networking Guidetreats such protocol settings as operational details, not architectural choices.

Conclusion:Option C belongs in the logical design, as it defines a scalable networking architecture critical to VCF 5.2’s multi-data center capabilities.References:
