When configuring Thin LUN, not all configured storage space is allocated upon creation. The storage space for Thin LUN will only be allocated when it is used.

Options:

False

True

Answer

Explanation

When configuring Thin LUN, not all configured storage space is allocated upon creation. The storage space for Thin LUN will only be allocated when it is used, allowing for more efficient use of storage resources.

Questions # 126:

An engineer maps the storage system to the file server to store various enterprise files. One day, the file system is attacked by viruses and files cannot be opened. To access the files, the engineer performs a snapshot rollback. Which statement is FALSE?

Options:

A snapshot rollback can quickly restore data.

When no host reads or writes data, the snapshot data is rolled back to the source volume in sequence.

Some data may be lost during a snapshot rollback.

If there are writes to the source LUN during a snapshot rollback, the rollback is performed after the writes are complete.

Answer

Explanation

If there are writes to the source LUN during a snapshot rollback, the rollback is performed before the writes are complete. This means that any data written to the source LUN during the snapshot rollback will be lost, since it will be overwritten by the snapshot data.

Questions # 127:

Questions # 128:

Which of the following is the most widely used FC topologies?

Options:

Point-to-Point.

FC Switched Network.

Arbitration Loop

FC Direct Connection.

Answer

Explanation

The most widely used Fibre Channel (FC) topology is the FC Switched Network. This topology uses a centrally managed switch to create a network of connected devices, allowing them to communicate with each other. This type of topology is highly scalable, as additional devices can be added to the network without any reconfiguration. It also provides higher performance than other topologies, as it can route data more quickly and efficiently.

Questions # 129:

A company purchases storage devices for new services. The new services do not require high access speed of storage devices. In this scenario, the IP SAN can be used for networking deployment.

Options:

False

True

Answer

Explanation

IP SANs are not suitable for deployments that do not require high access speeds, as they are optimized for fast storage access. In this scenario, a more suitable storage solution would be a Network Attached Storage (NAS) system [1], which is designed for slower access speeds.
