When you view the block device mapping for your instance, you can see only the EBS volumes, not the
instance store volumes.
A.
Depends on the instance type
B.
FALSE
C.
Depends on whether you use API call
D.
TRUE
When you view the block device mapping for your instance, you can see only the EBS volumes, not the instance store volumes.
When you view the block device mapping for your instance, you can see only the EBS volumes, not the
instance store volumes.
My view is that the correct answer is B:FALSE.
because “A block device mapping defines the block devices (instance store volumes and EBS volumes) to attach to an instance”.

Viewing the Instance Block Device Mapping for Instance Store Volumes
When you view the block device mapping for your instance, you can see only the EBS volumes, not the instance store volumes.
Answer is True : D
Answer is D
When you view the block device mapping for your instance, you can see only the EBS volumes, not the instance store volumes. You can use instance metadata to query the complete block device mapping. The base URI for all requests for instance metadata is http://169.254.169.254/latest/.

D
B – False
Like Cesar stated:
“A block device mapping defines the block devices (instance store volumes and EBS volumes) to attach to an instance.”
Also:
“You can use block device mapping to specify additional EBS volumes or instance store volumes to attach to an instance when it’s launched.”
From:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html#bdm-instance-metadata
Per: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html#bdm-instance-metadata
“When you view the block device mapping for your instance, you can see only the EBS volumes, not the instance store volumes. You can use instance metadata to query the complete block device mapping. The base URI for all requests for instance metadata is http://169.254.169.254/latest/.”
Correct answer is D.
A: is the correct answer
why??
instance store or ephemeral disk is attach only every instance type (except the micro instances) comes with instance storage.

D is the right answer, see here:

As Deepak Pant mentioned, the correct answer is A. Please see the following references for additional information:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html#instance-store-volumes
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-types.html#instance-networking-storage
Quote from the second link under “Storage features”:
“Some instance types support EBS volumes and instance store volumes, while other instance types support only EBS volumes. “
Answer is D
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/block-device-mapping-concepts.html
If the AMI was created with additional EBS volumes using a block device mapping, the Block Devices field displays the mapping for those additional volumes as well. (Recall that this screen doesn’t display instance store volumes.)

Are these dumps valid?
It seems the question is not being read properly.
Here is my attempted explanation which makes the answer C
(all command line are API calls).
Through the console you can only see EBS volumes.
By using the curl for the metadata, you can see non EBS (i.e )
$ curl http://169.254.169.254/latest/meta-data/block-device-mapping/
The response includes the names of the block devices for the instance. For example, the output for an instance store–backed m1.small instance looks like this.
ami
ephemeral0
)e.g
$ curl http://169.254.169.254/latest/meta-data/block-device-mapping/
The response includes the names of the block devices for the instance. For example, the output for an instance store–backed m1.small instance looks like this.
ami
ephemeral0
root
swap
The ami device is the root device as seen by the instance. The instance store volumes are named ephemeral[0-23]. The swap device is for the page file. If you’ve also mapped EBS volumes, they appear as ebs1, ebs2, and so on.
