Cloudera Manager in CCA 175

I would like to know CCA 175 exam infrastructure details.

1)Like How many datanodes, namenode ??

2)Cloudera Express or Cloudera Enterprise? Which one we will be able to use?

3)Do we need to start the services through CM or command line? VM comes up running services required for the exam.

Why is the reason for VM slowness in the exam is it our infrastructure problem or cloudera side infrastructure is slow?

@venkatwilliams, VM is not slow, since you access it remotely the access time is higher.
