NEW QUESTION # 29
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. Encrypted channels must be used for all communications.
- B. Communications must be through Private VLANs (PVLAN).
- C. Unauthorized access to interfaces must be reported within 15 minutes.
- D. Interfaces must be audited.
Answer: B
Explanation:
PVLANs divide the broadcast domain into multiple broadcast sub-domains and allow further isolating different devices within the same VLAN. They provide layer 2 isolation between ports within the same broadcast domain. 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." https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-70-security-guide.pdf

Site Recovery Manager must be used to orchestrate disaster recovery (DR) activities.
One single-sign on (SSO) domain must be used to authenticate access at both locations.
Which design decision should the architect make to meet these requirements?
- A. A vCenter Server will be installed on Windows virtual machines deployed to both sites.
- B. A vCenter Server Appliance will be deployed to the primary site only.
- C. A vCenter Server Appliance will be deployed to each site. Unique SSO domains will be created per site.
- D. A vCenter Server Appliance will be deployed to each site.

NEW QUESTION # 33
A customer requires the use of data encryption to ensure data is not accessible when a drive is removed from the primary storage platform. However, there is also a requirement to use deduplication and compression against all workloads in order to conserve space.
Which solution meets the customer requirements?
- A. Encrypted backups
- B. Array-based encryption
- C. OS-level encryption
- D. Data-in-transit encryption
Answer: B
Explanation:
Array-based encryption provides the same benefits as SEDs (self-encrypting drives), in that the drive shows no readable data once it is removed from the array. That means drives don't need to be physically destroyed when they are removed, which brings cost, security and environmental benefits

NEW QUESTION # 38
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. Use Network I/O Control to define a reservation for vMotion traffic.
- C. Implement Multi-NIC vMotion by adding additional vMotion VMkernels.
- D. Combine vMotion and Management traffic to make use of four adapters.
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 # 39
Which requirement would be classified as a functional requirement within the design documentation?
- A. The system must be able to scale to support 500 concurrent virtual machines.
- B. Virtual machines must be patched within one month of the patch release date.
- C. The system must perform virtual machine backups through an API.
- D. Virtual machines must be restarted within 30 minutes of a host failure.
Answer: A
NEW QUESTION # 40

The environment must support 5,000 virtual machines.
The environment will be built initially using 350 hosts.
Which vCenter Server appliance deployment size should the architect specify for the design?
- A. Small
- B. Medium
- C. Tiny
- D. Large
Answer: D
NEW QUESTION # 41
Refer to the exhibit.
During a requirements gathering workshop, the customer shares the following about their existing ESXi host virtual networking infrastructure:
The customer confirms that:
Each ESXi host has approximately 200 virtual machines.
They want to maximize the number of concurrent virtual machine migrations.
When placing a host in maintenance mode, it takes a long time to evacuate the virtual machines.
Which two recommendations should the architect make in order to help the customer overcome their challenge? (Choose two.)
- A. Create an additional standard switch with pNIC3 to use for vMotion
- B. Configure the network to use MTU for the VMotion VMKernel to 9,000 bytes
- C. Configure the network to use MTU for the VMotion VMKernel to 1,600 bytes
- D. Use 10 GbE NICs instead of 1 GbE
- E. Use the 3 pNICs and bundle them in a link aggregation group (LAG) configuration
Answer: B,D
Explanation:
https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vcenterhost.doc/GUID-7DAD15D4-7F41-4913-9F16-567289E22977.html
10Gb maximizes the amount of bandwidth, as well as increases the number of potential simultaneous vmotions.
