What is one of the key factors that can lead to slower performance in Bigtable?

• Inadequate network security

• Incorrect table schema design

• High number of queries per second

• Insufficient data encryption

Why is it essential to design a schema that allows reads and writes to be evenly distributed across the Bigtable cluster?

• To reduce costs

• To prevent node overload and improve performance

• To ensure data redundancy

• To comply with legal regulations

What is a potential issue if the workload is not appropriate for Bigtable?

• Increased storage costs

• Bigtable might not be able to optimize the data properly

• Risk of data loss

• Increased latency in network connections

How can you typically increase the performance of a Bigtable cluster?

• By reducing the number of nodes

• By using fewer monitoring tools

• By adding more nodes to the cluster

• By using HDD disks instead of SSD disks

How long can it take for Bigtable to optimally distribute cluster workload after scaling up the cluster?

• Almost immediately

• Up to 5 minutes

• Up to 10 minutes

• Up to 20 minutes

What is the performance difference between using HDD and SSD disks in Bigtable?

• HDD disks provide better performance than SSD disks

• SSD disks have slower response times than HDD disks

• SSD disks handle significantly more read requests per second than HDD disks

• HDD disks have a higher throughput than SSD disks

What should you do to avoid issues if your clients are not running in the same zone as your Bigtable cluster?

• Increase the number of nodes

• Use SSD disks

• Ensure your clients are in the same zone as your Bigtable cluster

• Decrease the row size

What does Bigtable's Key Visualizer tool help you analyze?

• Network performance

• Usage patterns of your Bigtable tables

• Data encryption status

• Cost efficiency

How does Key Visualizer represent low and high values in the heat map

• Low values are bright colors, high values are dark colors

• Low values are dark colors, high values are bright colors

• Both low and high values are represented in bright colors

• Both low and high values are represented in dark colors

What is necessary for valid performance test results on Bigtable?

• Tests on less than 100 gigabytes of data

• A short testing period of seconds

• Tests on at least 300 gigabytes of data over a long period

• Testing with no actual application code
