NEW QUESTION 31
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?
- A. vSAN network diagnostic mode is not enabled.
- B. vSAN proactive tests haven't been run yet.
- C. vSAN performance service is turned off.
- D. vSAN performance verbose mode is not enabled.
Answer: C
Explanation:
Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.
NEW QUESTION 32

- B. One of isolation addresses should reside in the site 1 data center
- C. The default gateway must be used as the only isolation address
- D. Host isolation response must exclude the VMs required
- E. One isolation address reachable only from the witness appliance in both sites

NEW QUESTION 35
Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.
The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.
The current vSAN cluster has the following configuration:
* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
* 1 Disk Group per vSAN node
- 1 x 400 GB
- 4 x 1.8 TB
* De-duplication and Compression is enabled.
* vSAN Capacity is currently:
- Total: 72 TB
- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).
As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.
Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)
- A. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
- B. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
- C. Install an additional 3 x 1.8 TB SSDs per vSAN node.
- D. Update the existing Disk Group, and claim the newly installed drives for each node.
- E. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
