NEW QUESTION # 31
A customer defines a requirement to minimize the vMotion migration time during a maintenance period. The servers being used are equipped with eight 1 GbE network adapters.
Per the defined logical network configuration, there are two network adapters each used for:
Management traffic
vMotion traffic
iSCSI traffic
Virtual machine traffic
Which design decision should the architect make to meet the customer requirement?
- A. Configure a dedicated TCP/IP stack for vMotion traffic.
- B. Combine vMotion and Management traffic to make use of four adapters.
- C. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
- D. Use Network I/O Control to define a reservation for vMotion traffic.
Answer: C
Explanation:
https://kb.vmware.com/s/article/2007467
https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-across-multiple-uplinks-on-distributed/td-p/491336
https://www.virtuallyboring.com/multi-nic-vmotion/
We maintain the 2 x 1 GbE network adapters for vMotion and then configure multiple VMkernel interfaces using the same NIC and network. Each time you add a VMkernel adapter and enable it for vMotion, you create a new stream. With more streams, there is greater bandwidth utilization.
https://kb.vmware.com/s/article/2007467
https://communities.vmware.com/t5/VMware-vSphere-Discussions/vmotion-load-balanced-across-multiple-uplinks-on-distributed/td-p/491336
https://www.virtuallyboring.com/multi-nic-vmotion/
Even though 2 x network adapters are dedicated to vMotion, only 1 of the uplinks will be used during a vMotion activity if only one vMotion vmkernel is configured. Adding an additional vmkernel will allow both to be used.
Per the VMware KB above "After making these configuration changes, when you initiate a vMotion, multiple NIC ports are used. Even when performing a vMotion on just one virtual machine, both links are used." Also the question states "Per the defined logical network configuration, there are two network adapters each" which suggests that changing this to combine vMotion/Mgmt traffic may not be possible based on the customers requirements (as the logical network architecture is already defined by them)
NEW QUESTION # 32

NEW QUESTION # 34
An architect is designing a series of new vSphere environments for an organization. The environments will be deployed in their US-East and US-West region data centers. Each data center may have one or more dedicated vSphere environments. Only the vSphere environments within a data center will be configured with Enhanced Linked Mode. The Chief Technology Officer (CTO) has authorized the use of VMware vRealize Automation Cloud for automation. The build team creates standardized virtual machine images for various operating systems in Open Virtualization Format (OVF) and publishes the latest version on an as-needed basis to an internal HTTPS-accessible repository.
The architect must design a content library topology that meets the following requirements:
A localized content library must be available in each data center.
Each content library must be updated when an image is updated and released by the build team.
The cloud automation platform must be able to consume the latest approved content library images.
It must leverage the existing build team processes.
What should the architect recommend to meet the requirements?
- A. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository.
Create a subscribed content library for each vSphere environment.
Configure the content library to download content automatically. - B. Work with the build team to automate a JSON-based manifest to the repository when changes occur in the repository.
Create a subscribed content library for each vSphere environment.
Configure the content library to download content when needed. - C. Work with the build team to create a local content library for each vSphere environment.
Import the OVF images when new image are published to the repository. - D. Create a local content library for the primary vSphere environment in each data center.
Create a subscribed content library for each additional vSphere environment in each data center.

NEW QUESTION # 37
An architect is tasked with designing a greenfield VMware software-defined data center (SDDC) solution that will be used to deliver a private cloud service for a customer.
During the initial meeting with the service owner and business sponsor, the customer has provided the following information to help inform the design:
The solution must support the concurrent running of 1,000 virtual machines The production environment must be delivered across two geographically dispersed data centers All virtual machines must be capable of running in either data center.
The two data centers are currently connected to each other through a single but diversely routed, high bandwidth and low latency link.
The link between the two data centers is capable of supporting a round-trip time (RTT) of 150 ms The existing server hardware standard document states that all virtual infrastructure hosts must be deployed using vSAN ReadyNodes The service owner has stated that it is critical to ensure the availability target of 99.9% All virtual machine backups must be completed using the existing backup service The recovery time objective (RTO) for the service is five minutes The recovery point objective (RPO) of the service is four hours Which two elements represent risks to the successful delivery of this solution? (Choose two.)
- A. The RTT on the link between the two data centers
- B. The use of only two data centers
- C. The network connectivity between data center sites
- D. The use of the existing backup service
- E. The use of vSAN ReadyNodes
Answer: C,D
Explanation:
B) The backup service has sufficient capacity for the new requirements
"All virtual machine backups must be completed using the existing backup service." The existing backup service may not have capacity or compatabiltiy for the new SDDC E) The clusters will have a minimum redundancy of N+1
"The service owner has said that is important to ensure that neither the availability target of 99.5% nor the resource capacity is affected when the operations team completes maintenance activities" We assume N+1 is sufficient. They may require a higher level of redundancy.

NEW QUESTION # 43
During a requirements gathering workshop, the customer provides the following requirement:
A new vSphere platform must be designed securely and all interfaces must be protected against potential snooping.
How should this non-functional security requirement be documented?
- A. Communications must be through Private VLANs (PVLAN).
- B. Interfaces must be audited.
- C. Encrypted channels must be used for all communications.
- D. Unauthorized access to interfaces must be reported within 15 minutes.
Answer: A
Explanation:
For example:
"Your ESXi host uses several networks. Use appropriate security measures for each network, and isolate traffic for specific applications and functions. For example, ensure that VMware vSphere vMotion traffic does not travel over networks where virtual machines are located. Isolation prevents snooping. Having separate networks is also recommended for performance reasons."

NEW QUESTION # 44
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. Separate the two resource profiles into two clusters. The Tier 1 cluster will have fast storage while the Tier 2 cluster will not.
- C. 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.
- D. Run both resource profiles on the same cluster with the same host hardware platform.
Answer: B
Explanation:
Checked in the training manual, chapter 10 Infrastructure Manageability: When mention about tiers... always talks about DIFFERENT CLUSTERS. Vmware suggest this in order to calculate spare hosts, cpu contention, disk performance, etc. In this case B and D should be disregarded, you should not mix Tier 1 and 2 in the same cluster.
