QUESTIONS AND CORRECT ANSWERS (VERIFIED
ANSWERS) |AGRADE
What is StorageGRID? – ANSWER- The StorageGRID is a Webscale object
storage that will allow you to manage explosive growth in unstructured data
created by multiple application and devices from globally distributed locations.
Allows users to have 24/7 access from any location. Allows for consumer to
choose their ideal hardware and support all industry standards protocols.
What is FlexPod? – ANSWER- FlexPod is a solution is a highly modular,
presesigned, best-practice datacenter architecture. It delivers a baseline
configuration that allows you to easily scale up as demands change. FlexPod
solutions has a cooperative support plan with all vendors.
What are the capabilities of FlexPod? – ANSWER- Reduced Risk(FlexPod
Solution is proven)
Increased Business Agility(Allows for rapid adjustment)
Reduced TCO(Total Cost of Ownership)
What is System Manager? – ANSWER- System Manager allows for management
of a small to midsize group of NetApp Systems. Customers can either use the CLO
or the GUI to manage resources in the cluster. It alllows for a centralized
management, monitoring, has a reporting tool so you can optimize the resources in
your cluster.
System Manager is offered at no cost when a Data ONTAP storage system is
purchased.
What protocols does Network Attached Storage use? – ANSWER- CIFS, NIFS
What protocols does Storage Attached Network use? – ANSWER- FC, FCoE,,
iSCSI
Compare and contrast the NAS and SAN protocols? – ANSWERHow does DAS work and what environment is it suited for? – ANSWER- Direct
Attached storage is directly attached to a server with no storage network in
between. DAS is ideal for localized file sharing in an environment with one server
or a few servers(Small Business with no need to share data over long distance)
DAS can be an individual disk on a client, server, a group of disk on a
server(internal or external).
What is Unified Storage Architecture? – ANSWER- Unified Storage Architecture
refers to the ablitiy to lin several kinds of storage together(SAN, NAS, private
cloud, public cloud, etc.)
Describe Network Attached Storage. – ANSWER- NAS combines the File System
and the Storage into one devices that is then kept outside the network. This makes
it easier the network and easier to manage. Access is preformed at the file level.
Describe Storage Attached Network. – ANSWER- The SAN is on its own network
for transporting files. The storage appears as disk drive that can be mounted on the
individual computers that use. it. Handle disaster recovery better but are more
complex to set up. Access is preformed at the block level.
Describe the FC-P2P topology. – ANSWER- Point to point is the simplest of the
FC typologies is connected directly to the host, however is very limited.
Describe the FC-AL topology. – ANSWER- Arbitrated Loop has all devices in a
loop, and allows for more connections than FC-P2P, however failure of one device
will break the loop.
Describe the FC-SW topology. – ANSWER- Switched Fabric has all
devices(storage devices/host) interconnected through FC switches. The switches
will provide optimized connections and security. There is both single and dual
layer.
What are the five main characteristics of cloud computing? – ANSWER- Self
Service
Broad Accessibility
Shared
Elastic
Measured/metered
What is self service according the cloud computing? – ANSWER- Allows
consumer to manager their own servers or have a developer API do so. On demand
component ensures resources are always available to the consumer.
What is broad accessibility according to cloud computing? – ANSWER- Services
are constantly being provided via multiple platforms. (ex laptop, desktop, mobile)
What is shared according to cloud computing? – ANSWER- Cloud resources are
pooled together to ensure maximum efficiency.
What is elastic according to cloud computing? – ANSWER- Resources(ex. CPU,
storage, memory) are dynamic and can be reallocated whenever needed.
What is measured meter according to cloud computing? – ANSWER- Cloud
resources used are monitored so you only pay for what you use. therefore it
becomes more cost effective.
What are the three main cloud environments? – ANSWER- Public, Private, Hybrid
Describe Public Cloud? – ANSWER- Resources are typically rendered over the
internet or an open network and are owned an operated by commercial providers.
Describe the Private Cloud? – ANSWER- Cloud resources are built specifically for
a group. Infrastructure can be hosted internally or externally, as well as managed
internally or by a third party.
Describe a Hybrid Cloud? – ANSWER- Its a combination of one or more private
and public clouds. It allows for consumer to meet their business requirements.
What are the three cloud delivery methods? – ANSWER- Infrastructure as a
Service(IaaS)
Platform as a Service(PaaS)
Software as a Service(SaaS)
Describe Internet as a Service(IaaS) – ANSWER- Focuses on the delivery of
virtual machines, block storage, firewall, software packages, and rack space.
Describe Platform as a Service(PaaS) – ANSWER- Focuses on the delivery of a
computing platform along with necessary application build/run environments such
as database, web server. This scales automatically to meet the demand.
Describe Software as a Service(SaaS) – ANSWER- Focuses on providing direct
functional access to the application and ;its capabilities.
