Identify the business challenge, ask performance questions, build the environment, rethink and test, analyze and report on results, summarize the away.
Which two challenges do scale-up storage architectures have? (Choose two.)
The cost of adding additional nodes becomes prohibitive.
It is difficult to scale performance as capacity grows.
Which form of NAND flash provides the most program-erase cycles?
Which option is the definition of "parity" in a RAID environment?
An error correction technique that improves fault tolerance
Which management platform does Cisco envision as the centralized control point for the data center that includes Cisco UCS Invicta?
Cisco UCS Director
Which option lists the system functions that are included in the scaling system router?
Node management, mirroring, and replication
Which option describes how Cisco solves the scaling solution problem that is associated with existing flash drive architectures?
Each Cisco UCS Invicta appliance and scaling system node has a dedicated router.
Which option is the IP address block of the default management interface?
Which option describes how Cisco UCS Invicta v5.x provides scalability?
Scale up / scale out
Which options are available when configuring a link aggregation bond in the Cisco UCS Invicta management interface?
Round robin, active backup, LACP, ALB
Which option describes how Cisco UCS Invicta uses cache?
It uses cache for reads and writes.
Which option describes why PCIe-based flash solutions are not a strong value proposition for VDI/desktop virtualization?
It is not a good fit at scale.
Which option describes how storage system scalability is achieved in a scale-out approach?
Adding more nodes to the existing storage system
Which two statements about the Cisco UCS Invicta scaling system nodes are true? (Choose two.)
Maximum raw capacity for a single node running in application acceleration mode is 24 TB.
Single node supports either asynchronous replication or data reduction.
Which port on the scaling system router must be used for management only?
Port 1 Bond 0
Which option describes the ring buffer and how it is used?
The ring buffer is where writes are queued before being written to disk. To protect against data loss, each write to the ring buffer is captured in a log file located on a persistent storage device.
Which two characteristics are common to OLTP transactions? (Choose two.)
Small, interactive transactions
A requirement for subsecond response times
Which two applications are best able to use data reduction nodes in the Cisco UCS Invicta scaling solution? (Choose two.)
Which description of the program-erase cycle is true?
It is a process where an entire page is read into the buffer, then the entire page is erased, and then the buffer is written back with any new or changed bits.
Which option is the technology that is used in Cisco UCS Invicta v5.0 to connect a scaling system router to a scaling system node?
Which option is the definition of the "RAID penalty"?
The extra wait time required for all operations required by the RAID level
How many IOPS does a typical VDI user require?
10 to 50
Which option must be considered when sizing a Cisco UCS Invicta appliance or Cisco UCS Invicta scaling system node?
SSD size, RAID 6 overhead, metadata, and garbage collection space
Which aspect of Cisco UCS Director offers task automation for Cisco UCS Invicta configuration?
Customized workflows using macros
Which two options are two characteristics of the Cisco UCS Invicta scaling system router? (Choose two.)
The storage router includes a ring buffer.
Cisco UCS Director can be used to manage the storage router.
Which protection mechanism is used by the Cisco UCS Invicta appliance to protect data writes if a power outage occurs?
The NVRAM card protects data in the event of power loss.
Which option describes the steps used by Cisco UCS Invicta to write to flash?
1) receive data, 2) optimize data, 3) protect data, 4) write data
Which interface types are supported in the PCIe slots of the scaling system node?
User-configurable interface cards are not supported.
Which mode must the Cisco UCS fabric interconnects be configured in when connecting the Cisco UCS Invicta to the Cisco UCS fabric interconnects through a Cisco Nexus 5000?
End host mode
Which Oracle database components do Cisco best practices include on LUN 1 for a simple Oracle physical layout?
Init.ora and sqlnet.ora
Which option describes how the "RAID penalty" applies to Cisco UCS Invicta?
Cisco UCS Invicta has a RAID write penalty of 0 because it implements an intelligent write algorithm that eliminates the additional operations required by the RAID level.
Which limitation do all flash arrays that use existing architectures suffer from as they scale up?
Restricted by the controller performance
Which two options are performance differences between Cisco UCS Invicta and PCIe flash memory? (Choose two.)
Cisco UCS Invicta provides much better benefit at scale for system boot storms.
Cisco UCS Invicta provides much better reduction in system boot time.
Which option is the proper power-on order when powering up a Cisco UCS Invicta Scaling System?
Power on the SSNs, then power on the SSRs.
