Which statement describes how drive performance and life is optimized in the Cisco UCS
Invicta appliance?

  • A. The Cisco UCS Invicta appliance system node creates and uses metadata stored on each 4K page to track drive wear.
  • B. The Cisco UCS Invicta OS creates and uses metadata stored on each 4K page to track drive wear.
  • C. The Cisco UCS Invicta appliance system router creates and uses metadata stored on each 4K page to track drive wear.
  • D. Drive wear is not an issue with the Cisco UCS Invicta appliance.


Answer : B

Explanation: This optimizes block erasing so that storage space is optimally utilized in order topreservethe life of the flash drive.

Which option is the approximate number of input/output operations of a typical solid state drive? (Assume a 4 K block size with 50% writes and 50% reads.)

  • A. About 100,000-200,000 IOPS
  • B. About 1,000-2,000 IOPS
  • C. About 100-200 IOPS
  • D. About 10,000-20,000 IOPS
  • E. About 1.000.000-2,000,000 IOPS


Answer : C

Explanation: SSD by itself brought an improvement of 100 + from what HDDs used to provide.

Which three options are available on the left navigation bar of the Cisco UCS Invicta appliance dashboard? (Choose three.)

  • A. Diagnostics
  • B. Reports
  • C. Performance Configuration
  • D. NAS Configuration
  • E. LUN Configuration
  • F. Users


Answer : C,D,E

Which limitation do all flash arrays that use existing architectures suffer from as they scale up?

  • A. Restricted by the network performance
  • B. Restricted by the host performance
  • C. Restricted by the disk performance
  • D. Restricted by the access performance
  • E. Restricted by the controller performance


Answer : E

Which three applications are best able to use performance nodes in the Cisco UCS Invicta scaling solution? (Choose three.)

  • A. Analytics
  • B. Desktop virtualization
  • C. Email
  • D. Batch data loads
  • E. OLTP
  • F. Bare metal applications


Answer : A,D,E

Explanation: Performance nodes are more suitable for options A,D & E; the other options wouldtake more advantage of data reduction nodes.

Which option describes the steps used by Cisco UCS Invicta to write to flash?

  • A. 1) receive data, 2) protect data, 3) write data, 4) optimize data
  • B. 1) receive data, 2) optimize data, 3) protect data, 4) write data
  • C. 1) receive data, 2) optimize data, 3) write data, 4) protect data
  • D. 1) receive data, 2) write data, 3) protect data
  • E. 1) receive data, 2) protect data. 3) optimize data, 4) write data


Answer : B

Explanation:
First UCS Invicta captures write requests, then organizes the data for optimal performance, then data is aligned for RAID protection in order to finally efficiently write data.

Which port on the scaling system router must be used for management only?

  • A. Port 3 Bond 0
  • B. Port 1 Bond 0
  • C. Port 2 Bond 0
  • D. Port 4 Bond 0


Answer : B

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?

  • A. 802.11ac
  • B. LSI
  • C. Ethernet
  • D. Fibre Channel
  • E. InfiniBand


Answer : E

Explanation: Explained: InfiniBand connections communicate routers and nodes.

Which option describes how the "RAID penalty" applies to Cisco UCS Invicta?

  • A. Cisco UCS Invicta has a RAID write penalty of 2
  • B. 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.
  • C. Cisco UCS Invicta has a RAID write penalty of 0 because it does not use RAID.
  • D. Cisco UCS Invicta has a RAID write penalty of 4.
  • E. Cisco UCS Invicta has a RAID write penalty of 6.


Answer : B

Explanation: UCS Invicta uses the Block Translation Leyer for write optimization, this cause RAID penalty to be 0 and reads/writes to take almost the same time.

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 SAN?

  • A. N-Port virtualization mode
  • B. End host mode
  • C. Ethernet switched mode
  • D. Ethernet switched end host mode


Answer : B

Which option describes why PCIe-based flash solutions are not a strong value proposition for VDI/desktop virtualization?

  • A. The industry favors AGP-based flash solutions because the bus speed is faster.
  • B. It is not a good fit at scale.
  • C. It improves I/O speed, but nothing else.
  • D. Its purchase price is too high.
  • E. The industry favors USB-based flash solutions because it is more common.


Answer : B

Explanation: PCIe based solutionmightprovide performance necessary within the calculated threshold, but doesn't scale well when trying to add more virtualization.

Which two challenges do scale-up storage architectures have? (Choose two.)

  • A. Adding additional nodes to the system requires some scheduled downtime.
  • B. The cost of adding additional nodes becomes prohibitive.
  • C. Remote replication is complex because data is replicated across nodes to ensure data availability.
  • D. Performance is difficult to predict with features such as deduplication.
  • E. It is difficult to scale performance as capacity grows.


Answer : B,D

Which option must be considered when sizing a Cisco UCS Invicta appliance or Cisco UCS
Invicta scaling system node?

  • A. SSR speed, RAID 6 overhead, metadata, and garbage collection space
  • B. SSN speed, RAID 6 overhead, metadata, and garbage collection space
  • C. SSD speed, RAID 6 overhead, metadata, and garbage collection space
  • D. SSD size, RAID 6 overhead, metadata, and garbage collection space


Answer : D

Which option describes valid targets for asynchronous replication?

  • A. Cisco UCS Invicta appliances, scaling systems, and Windows / Linux / Solaris machines
  • B. Cisco UCS Invicta appliances, scaling systems, and Windows / Linux machines
  • C. Cisco UCS Invicta appliances and scaling systems only
  • D. Cisco UCS Invicta scaling systems and Windows / Linux / Solaris machines
  • E. Cisco UCS Invicta scaling systems and Windows / Linux machines
  • F. Cisco UCS Invicta scaling systems only


Answer : E

Explanation:
Whether you're in a Scaling System or Appliance, replication is only possible to Scaling
System or to an open target runing Windows or Linux.

Which option describes how storage system scalability is achieved in a scale-up approach?

  • A. Deduplicating data, which increases the effective capacity of the system
  • B. Distributing data across nodes to increase aggregate performance
  • C. Adding capacity to the existing storage system
  • D. Adding more nodes to the existing storage system
  • E. Distributing data across SSDs to increase aggregate performance
