      (1/5)
      1. Which Google Cloud machine family is best suited for cost-effective general use workloads?
      easy
      A. E2 family
      B. N2 family
      C. C2 family
      D. M1 family

      Solution

      1. Step 1: Understand the purpose of each machine family

        The E2 family is designed for cost-effective general use, N2 balances power and memory, and C2 is optimized for CPU-heavy tasks.

      2. Step 2: Match the workload type to the machine family

        Since the question asks for cost-effective general use, E2 is the best fit.

      3. Final Answer:

        E2 family -> Option A

      4. Quick Check:

        Cost-effective general use = E2 [OK]
      Hint: E2 means economical general use machines [OK]
      Common Mistakes:
      • Confusing C2 as cost-effective instead of CPU-optimized
      • Choosing N2 for cost savings instead of balance
      • Selecting a non-existent machine family like M1
      2. Which of the following is the correct way to specify a C2 machine type in a Google Cloud VM instance configuration?
      easy
      A. machineType: 'zones/us-central1-a/machineTypes/m1-standard-4'
      B. machineType: 'zones/us-central1-a/machineTypes/e2-standard-4'
      C. machineType: 'zones/us-central1-a/machineTypes/n2-standard-4'
      D. machineType: 'zones/us-central1-a/machineTypes/c2-standard-4'

      Solution

      1. Step 1: Identify the correct machine family prefix for C2

        C2 machine types start with 'c2-', so the machine type string must include 'c2-standard-4'.

      2. Step 2: Verify the full machineType format

        The format is 'zones/{zone}/machineTypes/{machineType}', so 'zones/us-central1-a/machineTypes/c2-standard-4' is correct.

      3. Final Answer:

        machineType: 'zones/us-central1-a/machineTypes/c2-standard-4' -> Option D

      4. Quick Check:

        C2 machine type string includes 'c2-' prefix [OK]
      Hint: C2 machine types start with 'c2-' in the path [OK]
      Common Mistakes:
      • Using 'e2-' or 'n2-' prefix for C2 machines
      • Incorrect zone or path format
      • Using a non-existent machine family like 'm1-'
      3. You launch a VM with machine type n2-standard-8. Which statement best describes this VM's characteristics?
      medium
      A. It is optimized for CPU-heavy workloads with 8 vCPUs.
      B. It balances CPU and memory with 8 vCPUs and moderate RAM.
      C. It is a cost-effective VM with limited CPU power.
      D. It is a high-memory VM with 8 vCPUs and extra RAM.

      Solution

      1. Step 1: Understand the N2 machine family purpose

        N2 machines balance CPU power and memory, suitable for general workloads needing moderate resources.

      2. Step 2: Analyze the machine type suffix

        'standard-8' means 8 virtual CPUs with balanced memory, not specialized for CPU-only or high-memory.

      3. Final Answer:

        It balances CPU and memory with 8 vCPUs and moderate RAM. -> Option B

      4. Quick Check:

        N2 = balanced CPU and memory [OK]
      Hint: N2 means balanced CPU and memory machines [OK]
      Common Mistakes:
      • Confusing N2 with C2 which is CPU-optimized
      • Thinking N2 is cost-effective like E2
      • Assuming N2 is high-memory only
      4. A user tries to create a VM with machine type c2-standard-16 but gets an error. Which is the most likely cause?
      medium
      A. The zone does not support C2 machine types with 16 vCPUs.
      B. The machine type name is misspelled; it should be c2-standrd-16.
      C. C2 machines cannot have more than 8 vCPUs.
      D. The user must specify the machine type without the zone prefix.

      Solution

      1. Step 1: Check machine type naming and limits

        'c2-standard-16' is a valid machine type with 16 vCPUs; spelling is correct and allowed size.

      2. Step 2: Consider zone availability

        Some zones do not support all machine types or sizes, so the error likely comes from zone limitations.

      3. Final Answer:

        The zone does not support C2 machine types with 16 vCPUs. -> Option A

      4. Quick Check:

        Zone support limits cause machine type errors [OK]
      Hint: Check zone supports machine type size before creating VM [OK]
      Common Mistakes:
      • Assuming spelling error when name is correct
      • Believing C2 max vCPUs is 8 (it's higher)
      • Ignoring zone prefix requirement in machineType
      5. You need to run a CPU-intensive data processing job that requires maximum CPU power but moderate memory. Which machine type should you choose to optimize performance and cost?
      hard
      A. e2-standard-16
      B. n2-highmem-16
      C. c2-standard-16
      D. e2-highcpu-16

      Solution

      1. Step 1: Identify workload requirements

        The job is CPU-intensive needing maximum CPU power with moderate memory.

      2. Step 2: Match machine family to workload

        C2 family is optimized for CPU-heavy workloads, while E2 is cost-effective general use and N2-highmem is for memory-heavy tasks.

      3. Step 3: Choose the best machine type

        Among options, 'c2-standard-16' provides high CPU power with balanced memory, fitting the requirement best.

      4. Final Answer:

        c2-standard-16 -> Option C

      5. Quick Check:

        CPU-heavy job = C2 machines [OK]
      Hint: Use C2 for CPU-heavy jobs, not E2 or N2-highmem [OK]
      Common Mistakes:
      • Choosing E2 for CPU-heavy instead of cost-effective use
      • Picking N2-highmem which wastes cost on extra memory
      • Selecting E2-highcpu which is less powerful than C2
