An architect is creating a network design for a new vSphere environment.
Based on customer requirements, the environment must support the following types of traffic:
Management
vMotion
vSAN
Fault Tolerance
Virtual machine traffic, which cannot be impacted by other types of traffic Which design recommendation can the architect make for a resilient infrastructure with vSphere network service tiering?

• A.Use a NIC teaming policy based on the physical NIC load
• B.Use Network I/O Control and ensure appropriate share value is defined for different types of traffic giving priority to the virtual machines traffic
• C.Use different logical networks to ensure traffic is isolated with separate VLANs
• D.Use two dedicated virtual switches with a single adapter each, dedicating one virtual switch for Management, vMotion, vSAN and Fault Tolerance traffic, and the second one for virtual machine traffic

Refer to the exhibit.
During a requirements gathering workshop, the customer shares the following diagram regarding their availability service-level agreements (SLAs):

The customer wants database application level availability to always take precedence. What should the architect recommend to meet the customer's requirement?

• A.Enable vSphere HA and add a VM Override with VM Restart Priority set to Lowest.
• B.Enable Sphere HA and maintain the default settings.
• C.Enable vSphere HA and add a VM Override with VM Restart Priority set to Highest.
• D.Enable Fault Tolerance.

An architect is designing a solution for an environment with two types of resource profiles that must be virtualized. The first type consists of Tier 1 virtual machines that are disk I/O intensive, but do NOT require high CPU or memory. The second type consists of Tier 2 virtual machines that require a lower CPU and memory allocation and have minimal disk I/O.
Which design recommendation should the architect make for distributing the resource profiles?

• A.Run both resource profiles on the same cluster with host hardware that has fast CPU, large amounts of memory, and the fastest storage platform.
• B.Run both resource profiles on the same cluster with the same host hardware platform.
• C.Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.
• D.Separate the two resource profiles into two clusters. The Tier 2 cluster will have faster CPU and more memory while the Tier 1 cluster will have slower CPU and less memory but more disk space.

Which requirement would be classified as a functional requirement within the application design documentation?

• A.Penetration testing must be executed quarterly with a pass rate of 80% or higher.
• B.The application must be capable of handling 200 transactions per second.
• C.Administrators must monitor the network traffic of the desired systems.
• D.The application must be hosted with redundancy levels of N+1 or better.

A customer requests a review of its current vSphere platform design.
The following information is noted:
There are three different workload profiles for the virtual machines:
Tier-1 virtual machines operate resource-intensive applications and require dedicated allocations for CPU and RAM.
Tier-2 virtual machines operate internet-facing applications and require access to externally facing networks.
Tier-3 virtual machines operate platform management tools such as vCenter Server and have different lifecycle management requirements.
Tier-1, Tier-2 and Tier-3 virtual machines are all hosted on a single large vSphere cluster.
The Chief Information Security Officer (CISO) has raised concerns that hosting externally facing applications alongside management tools does not meet internal compliance standards.
The Operations team has raised concerns about Tier-1 virtual machines negatively impacting the performance of vCenter Server.
The Operations lead has stated that management changes have consistently been rejected by application teams.
As a result of the review, which recommendation should the architect make regarding the design of this platform?

• A.Separate Tier-1, Tier-2 and Tier-3 virtual machines using resource pools and shares
• B.Separate Tier-1, Tier-2 and Tier-3 virtual machines using dedicated distributed virtual switches (DVS)
• C.Separate Tier-1, Tier-2 and Tier-3 virtual machines onto dedicated clusters
• D.Separate Tier-2 virtual machines onto a dedicated cluster
