Disk IOPS scales based on what factors? - ANSWER-Size of disk
vCPUs (if needed to avoid the network egress cap)
Network egress cap - ANSWER-GCP limits egress traffic to 2 Gbps per vCPU for
machine types with eight or fewer vCPUs. Machine types with more than eight vCPUs
are limited to 16 Gbps, and shared-core machine types are limited to 1 Gbps.
True or False: Local SSD is high-performance persistent block storage. - ANSWER-
False
It is transient, not persistent.
True or false: Storage changes are based on the storage class of individual objects, not
the default storage class set on the bucket. - ANSWER-True
The default storage class merely determines the storage class for *new* objects (unless
overridden).
What are the default network rules? - ANSWER-All are ingress rules:
default-allow-internal - allows ingress for all protocols and ports *within the network*
default-allow-ssh, default-allow-rdp, default-allow-icmp - allow ingress for 0.0.0.0/0 for
the protocol and its associated port (22, 3389)
What are three ways to scale up your Cloud SQL? - ANSWER-1 - Easy: Make current
instance larger, or scale out with read replicas
2 - Medium: Break apart the database into multiple Cloud SQL instances
3 - Hard: Move to Cloud Spanner
What could limit a VM's disk performance? - ANSWER-Network egress cap
What determines the speed of a Cloud Datastore query?
The size of the database
The size of the query results
The number of joins - ANSWER-The size of the query results
What is the availability for regional and multi-regional Cloud Storage? - ANSWER-
99.5%
What is the difference between interconnect services and peering services? -
ANSWER-Interconnect provides access via private IP addresses (RFC 1918), while
peering services operate using public IP addresses.
Peering can also save up to 67% on egress fees compared to VPN or public access
over the internet
, What is the implied egress rule? - ANSWER-For all networks, an egress rule whose
action is *allow*, destination is 0.0.0.0/0
What is the implied ingress rule? - ANSWER-For all networks, an ingress rule whose
action is *deny*, source is 0.0.0.0/0
What is the maximum size of a Cloud SQL database? - ANSWER-10 TB (2nd
generation)
What is the maximum size of a persistent disk? - ANSWER-64 TB
What is the scope of a network in VPC? - ANSWER-Global
When is the Google Transfer Appliance recommended?
For transfers over 1 TB
For transfers over 20 TB
For transfers over 1 PB
For transfers over 20 PB - ANSWER-For transfers over 20 TB
