Explanation
An OSD storage system is an object-based storage system that stores data as objects rather than files or blocks
1. An OSD storage system consists of OSD nodes that have two key services: metadata service and storage service1.
The metadata service is responsible for generating the object ID from the contents of a file1. The object ID is a unique identifier that represents the data and its attributes. The metadata service also maintains the mapping of the object IDs and the file system namespace1. The file system namespace is a logical structure that organizes files into directories and subdirectories.
The storage service manages a set of disks on which the user data is stored1. The storage service stores data as objects in physical OSD containers. Each OSD container has a unique address that corresponds to an object ID. The storage service also handles requests from clients to read or write data to or from objects.

QUESTION 30
What is an accurate statement about variable prefetching?
Response:

Many blocks that have recently been written to storage by the compute system are retrieved and placed in cache.

Many non-contiguous blocks that are not currently required can be retrieved from cache in advance.

Storage system prefetches data in multiples of the original I/O request size from the compute system.

Storage system prefetches many non-contiguous blocks of data, with varied sizes, from cache.

QUESTION 31
What is an accurate statement about stretched VLANs?
Response:

Reduces network bandwidth requirements during VM migration across sites.

Requires a change in the VMs’ IP addresses to match the addressing scheme at the other sites.

Enables automatic modification of VLAN addresses during VM migration across sites.

Supports migration of VMs across sites without the need to change their network configurations.

QUESTION 32
Which type of login assigns an FC address to a node in an FC SAN environment?
Response:

PRLI

FLOGI

WWNN

PLOGI

QUESTION 33
What is a benefit of using the FCoE storage protocol?

Fewer physical Fibre Channel and Gigabit Ethernet switches are required.

Fewer physical storage systems are required when using FC SAN and iSCSI enabled storage systems.

Fewer physical host Ethernet network adapters are required when using CNA adapters.

Fewer physical storage systems are required when using FC SAN and FCoE enabled storage systems.
