Enable NIOC when not using dedicated network connections for vSAN networking traffic. B. Use two or more vSAN VMkernel ports on the same subnet to configure MPIO. C. Use 3 or more network connections for a vSAN VMkernel Port. D. For hybrid configurations, use dedicated 1Gbps network connections or 10 Gbps shared network connections. Answer: A D Explanation IT Certification Guaranteed, The Easy Way! 25
A: If you use a shared 10-GbE network adapter, place the vSAN traffic on a distributed switch and configure Network I/O Control to guarantee bandwidth to vSAN. D: For hybrid configurations, dedicate at least 1-GbE physical network adapter. Place vSAN traffic on a dedicated or shared 10-GbE physical adapter for best networking performance. - 7BDE36E1-2F06 NO.79 Which three virtual machine file types are contained in a VM home namespace object in a vSAN cluster? (Choose three.) A. .vmx B. .swap C. .log D. .memory E. .nvram Answer: A C E Explanation The virtual machine home directory where all virtual machine configuration files are stored, such as .vmx, log files, vmdks, and snapshot delta description files. The VM Home Namespace is where we store all the virtual machine configuration files, such as the .vmx, .log, digest files, memory snapshots, etc. The .nvram file: this is the file that stores the state of the virtual machine's BIOS. This file is stored in the same directory as the .vmx file. NO.80 Which two statements are true about the vSAN health and performance services? (Choose two.) A. The vSAN performance service must be enabled before the vSAN health service. B. The vSAN health service is enabled by default. C. The vSAN health service is disabled by default. D. The vSAN performance service is disabled by default. Answer: B D NO.81 Which three objects that belong to virtual machines are contained in a vSAN datastore? (Choose three.) A. VM Health Status B. VMDK C. VM Home Namespace D. Performance Statistics E. VM Swap Answer: B C E NO.82 To which two items can a vSAN storage policy be applied? (Choose two.) A. All objects that make up the virtual machine B. Only virtual hard disks IT Certification Guaranteed, The Easy Way! 26
C. Individual objects that make up the virtual machine D. Storage folder Answer: A B NO.83 Which statement accurately describes cache tier sizing guidance for an all-flash vSAN cluster that will be supporting write-intensive workloads? A. Multiple disk groups with larger cache devices should be used. B. Multiple disk groups with two cache devices per disk group should be used. C. A single disk group with a small cache device should be used to minimize de-staging write amplification. D. Two cache devices per disk group should be configured for redundancy. Answer: A Explanation While 1 to 5 disk groups per host are supported, we recommend a minimum of 2. Adding more disk groups can improve performance.
