3. Question 43 · 57 in bank

   You have an instance running in Oracle Cloud Infrastructure (OCI) that cannot be live-migrated during an infrastructure maintenance event. OCI schedules a maintenance due date within 14 to 16 days and sends you a notification. What would happen if you choose not to proactively reboot the instance before the scheduled maintenance due date?

   • AYou will receive another notification to reboot within the next 14 days.
   • BThe instance will get terminated.
   • CThe instance is either reboot-migrated or rebuilt in place for you.
   • DYou will receive another notification to reboot within the next 7 days.

   Show answer

   Answer: C

   Explanation

   C is correct. If you do not proactively reboot the instance before the due date, the instance is reboot migrated for you. By default, Oracle Cloud Infrastructure live migrates the instance without sending any notification about the upcoming maintenance.

   Which TWO statements are NOT correct regarding the Oracle Cloud Infrastructure (OCI) burstable instances? (Choose two.)

   • AIf the instance's average CPU utilization over the past 24 hours is below the baseline, the system allows it to burst above the baseline.
   • BBurstable instances are charged according to the baseline OCPU.
   • CBurstable instances cost less than regular instances with the same total OCPU count.
   • DBaseline utilization is a fraction of each CPU core, either 25% or 75%.
   • EBurstable instances are designed for scenarios where an instance is not typically idle and has high CPU utilization.

9. Question 49 · 57 in bank

   Company XYZ is spending $300,000.00 USD per month in egress fees for 7 Petabytes (1 Petabyte = 1000 Terabytes) that they consume for Outbound Data Transfer in North America with their current cloud provider. The company is seeking to lower that expense considerably without reducing consumption. You propose migration to OCI because the Gigabyte Outbound Data Transfer in North America costs just $0.0085 USD per month. With OCI, how much will they spend per month for 7 Petabytes of Outbound Data Transfer? (1 Terabyte = 1000 Gigabytes)

   • A$59,415.00
   • B$150,000.00
   • C$0.00 (free with OCI)
   • D$59,500.00

   Show answer

   Answer: D

   Explanation

   Not sure why the correct answer is marked as A. 0.00085 x 1000 = 8.5 (so the cost for 1TB is $8.5) 8.5 x 1000 = 8.500 (so the cost for 1PB is $8500) 8.5000 x 7 = 59.500 (so the cost for 7PT is 59,500) The correct answer should be D

10. Question 50 · 57 in bank

    Which is NOT a valid Oracle Cloud Infrastructure (OCI) Virtual Cloud Network (VCN) design approach?

    • APrivate subnets should ideally have individual route tables to control the flow of traffic within and outside of VCN.
    • BEnsure not all IP addresses are allocated at once within a VCN or subnet; instead reserve some IP addresses for future use.
    • CUse OCI tags to tag VCN resources so that all resources follow organizational tagging/naming conventions.
    • DFor resources without public IP addresses that need to initiate connections to the internet you can use an Internet gateway.

    Show answer

    Answer: D

    Explanation

    I really do not understand how they got A but this is a straight forward calculation that gives D 1000* 1000* 7 *.0085=59500 USD for 7Petabyte
