D. Operating System customization
E. Network Storage requirements
B. Google Cloud Storage required
Google Compute Engine performance consideration, Which one is not a valid parameter to consider?
​
A. Which hardware the VM is hosted
B. Network Performance
C. Disk IOPS
D. No of vCPU
E. GB's of RAM
A. Which hardware the VM is hosted
What is not true about connecting to google Compute Engine (VM)?
​
A. You can use rdp to connect to Windows VM
B. You can not use third party ssh client to connect linux VM
C. You can use ssh to connect to Linux VM
D. You can connect using rdp or ssh from cloud console

C. ipaddress external
D. gsutil
A. gcloud
You can not attach GPU for following machine types
​
A. Shared Core
B. Custom machine
C. Standard
D. High Memory
E. High CPU
A. Shared Core
VM network performance depends on following parameters
​
A. Number of vCPUs
B. GBs of RAM
C. Number of disks attached
D. Network Interface attached
A. # of CPUs.
Here is the link Chunghttps://cloud.google.com/blog/products/gcp/5-steps-to-better-gcp-network-performance?hl=mlExplanationOutbound or egress traffic from a virtual machine is subject to maximum network egress throughput caps. These caps are dependent on the number of vCPUs that a virtual machine instance has. Each core is subject to a 2 Gbits/second (Gbps) cap for peak performance. Each additional core increases the network cap, up to a theoretical maximum of 16 Gbps for each virtual machine.
In other words, the more virtual CPUs in a guest, the more networking throughput you get
What are not considerations for choosing Local SSD
A. Local SSD is ephemeral
B. VM with local SSD can not live migrate with data stored on local SSD
C. Local SSD can be up to 3 TB
D. You can use only one local disk per VM
E. Local disk size is fixed size.
D. You can use only one local disk per VM
Attach up to 24 Local SSD partitions for 9 TB of total Local SSD storage space per instance. Or you can format and mount multiple Local SSD partitions into a single logical volume.
Custom VM may cost you highest than that of equivalent predefined VM.
​
A. TRUE
B. FALSE
True.
Google Compute Engines number of vCPUs are dependent on CPU platform.
​
A. TRUE
B. FALSE
True
External IP address is visible inside Google Cloud Compute Engine.
A. True
B. False
True. External IP address
External IP addresses are publicly advertised, meaning they are reachable by any host on the internet. External IP addresses must be publicly routable IP addresses. Resources with external IP addresses can communicate with the public internet.
There are Managed and unmanaged Instance groups in GCE.
​
FALSE
​
TRUE
True. We have both managed and unmanged
You can not auto scale in ummanaged instance group.
​
TRUE
​
FALSE
True, you need managed instance group if you want auto scale
