Answer: After running `dbutils.fs.refreshMounts()`, the mount point becomes accessible on the `prod-support` cluster.
The correct answer is E because the mount point created on the `s3mount` cluster is not automatically available on the `prod-support` cluster. To make the mount point accessible on an already running cluster like `prod-support`, the data engineer must execute `dbutils.fs.refreshMounts()`. This action refreshes the mount points across the workspace, enabling access to the mounted S3 bucket from the `prod-support` cluster. More Info: Refreshing a Mount point in Databricks

A data engineer has created a new cluster named s3mount and attached a notebook to it, which mounts an S3 bucket to DBFS. Other data engineers are using an existing cluster named prod-support for their notebooks. If one of these engineers attempts to access the data from the mount point using their notebook, what can be said about the data accessibility?
A
The data engineer will encounter no errors and can access the data immediately.
B
The mount point is exclusively accessible through notebooks attached to the s3mount cluster.
C
For data access on the prod-support cluster, executing dbutils.refreshMounts() is necessary.
D
Restarting the cluster is the sole method to access the data on the s3mount cluster.
E
After running dbutils.fs.refreshMounts(), the mount point becomes accessible on the prod-support cluster.
