What is the requirement for each external VM Direct engine?

Question

Options

• A4 CPU, 8 GB of RAM, 152 GB
• B4 CPU, 8 GB of RAM, 157 GB
• C2 CPU, 10 GB of RAM, 59 GB
• D6 CPU, 16 GB of RAM, 157 GB

• A
  4% (2)
• B
  92% (46)
• C
  2% (1)
• D
  2% (1)

Explanation

Option B (4 CPU, 8 GB RAM, 157 GB) matches the documented minimum resource requirements for an external VM Direct engine, as specified in Veeam Backup & Replication's infrastructure guidelines. The 157 GB storage accounts for the OS footprint, Veeam software installation, and required working/cache space for data movement operations.

Why the distractors are wrong:

• A (152 GB): Undershoots the storage requirement by 5 GB - a common trick to test whether you know the exact figure.
• C (2 CPU, 10 GB RAM, 59 GB): Both CPU and storage are too low for a proxy handling VM data traffic; the RAM is oddly high relative to the other specs, making it a plausible-sounding but fabricated combination.
• D (6 CPU, 16 GB RAM, 157 GB): The storage is correct, but CPU and RAM are over-specified beyond the minimum requirement - designed to trap candidates who confuse minimum with recommended specs.

Memory tip: Think "4-8-157" as a sequence - the numbers roughly double and then jump: 4 CPUs, 8 GB (double the CPUs), and 157 GB storage. If you remember that storage ends in 7 (not 2), you can immediately eliminate option A and lock in B.
