An AWS Snowball appliance includes a(n) network connection to minimize data transfer times.

  1. 10GBaseT
  2. 1000BaseT
  3. 40GBaseT
  4. Infiniband

Answer(s): A

Explanation:

An AWS Snowball appliance has a 10GBaseT network connection (both RJ45 as well as SFP+ with either a fiber or copper interface) to minimize data transfer times. This allows the Snowball appliance to transfer up to 80 terabytes of data from a data source to the appliance in about a day, plus shipping time.

Which statements are true about re-sharding in Amazon Kinesis?

  1. The shard or pair of shards that result from the re-sharding operation are referred to as child shards.
  2. When you re-shard, data records that were flowing to the parent shards are rerouted to flow to the child shards based on the hash key values that the data record partition keys map to.
  3. The shard or pair of shards that the re-sharding operation acts on are referred to as parent shards.
  4. After you call a re-sharding operation, you do not need to wait for the stream to become active again.

Answer(s): A,B,C

Explanation:

Kinesis Streams supports re-sharding which enables you to adjust the number of shards in your stream in order to adapt to changes in the rate of data flow through the stream.
The shard or pair of shards that the re-sharding operation acts on are referred to as parent shards. The shard or pair of shards that result from the re-sharding operation are referred to as child shards. After you call a re-sharding operation, you need to wait for the stream to become active again.
When you re-shard, data records that were flowing to the parent shards are rerouted to flow to the child shards based on the hash key values that the data record partition keys map to.
