Riverbed Riverstone Certification 101-01 Questions & Answers

• Question 41:

  Which report would you use to monitor disk utilization in the SteelHead management console user interface?

  A. Reports > Data Store Cost

  B. Reports > Data Store Disk Load

  C. Reports > Data Store Hit Rate

  D. Reports > Data Store Status

  Correct Answer: B

  The Data Store Disk Load report summarizes the data store disk load due to SDR-only as related to the benchmarked capacity of the data store. Consider any value under 100 as healthy. Any value higher than 100 might indicate disk pressure. When a value is consistently higher than 100, contact Riverbed Professional Services for guidance on reconfiguring the data store to alleviate disk pressure.

  The Data Store Disk Load report answers the following questions:

  *

  Is there any indication of disk pressure?

  *

  What is the disk load at different times of the day? Incorrect:

  Not A: The Data Store Cost report summarizes the relative cost of doing data store operations.

  The Data Store Cost report answers the following questions:

  *

  Is the data store load healthy?

  *

  Is there possible disk pressure?

  *

  What is the relative load at different times of the day?

  Not C: The Data Store Hit Rate report answers the following questions:

  *

  How much optimization is occurring?

  *

  How much optimization occurred through SDR hits?

  *

  How much data traversed the WAN without optimization?

  Not D: The Data Store Status report answers the following questions:

  *

  Is the synchronization connection active?

  *

  Is the Steelhead appliance in the Catch-up or Keep-up phase of data store synchronization?

  *

  What percentage of the data store is unused?

• Question 42:

  You wish to pass-through traffic to a particular server from a large number of remote sites, all optimized by SteelHeads. You know that it can be done on a single SteelHead. Which type of rule would you configure?

  A. Peering pass-through rule on the server-side SteelHead

  B. Peering pass-through rule on the client-side SteelHead

  C. In-path pass-through rule on the server-side SteelHead

  D. In-path pass-through rule on the client-side SteelHead

  Correct Answer: B

  Configuring Pass-Through Transit Traffic Transit traffic is data that is flowing through a Steelhead appliance whose source or destination is not local to the Steelhead appliance. This can be configured through Manual peering and in-path rules.

• Question 43:

  The CIFS latency optimization feature provides which performance benefits? (Choose two.)

  A. Read-ahead and write-behind optimizations

  B. Data reduction over the WAN

  C. Latency reduction through transaction prediction

  D. Data encryption over the WAN

  Correct Answer: BC

  CIFS optimization focuses on reducing the impact of WAN round-trip latency of common application and

  system behavior.

  RiOS can perform full latency and bandwidth optimization securely for SMB signed traffic.

• Question 44:

  A service provider would like to implement multi-tenanting on a SteelCentral Controller for SteelHead (SCC) such that the customers would be able to run their own reports. Which of the following are true?

  A. SCC does not support multi-tenancy. A virtual or physical SCC would need to be provisioned for each customer.

  B. The SSL certificate for SCC management would need to be distributed to the customers.

  C. RADIUS or TACACS+ would need to be used to offload the authentication to achieve the privileges required.

  D. HTTP server should be disabled for the web UI and only SSL used.

  E. Each customer would have to be configured with privileges for their own SteelHeads and no others.

  Correct Answer: A

  Controller-v is a virtualized appliance of the SteelCentral Controller for SteelHead specifically designed for

  customers (such as Managed Service Providers) and users who need to centrally manage multiple,

  separate deployments of the Riverbed system on behalf of their customers.

• Question 45:

  What does "Branch managed" mean when adding a SteelHead to the SteelCentral Controller for SteelHead (SCC) inventory?

  A. This SteelHead is fully managed by the SCC.

  B. This SteelHead has SteelFusion capability.

  C. Another SCC as well as this one manages this SteelHead.

  D. This SteelHead supports DNS caching and/or RSP or VSP policies.

  E. The SteelHead is not under control of the SCC. Only reports and status information are available.

  Correct Answer: E

  Branch managed specifies the appliance is managed individually at the branch office. You cannot manage this SteelHead from the SCC.

• Question 46:

  What is the default data store size for a SteelHead Mobile Client?

  A. 1 GB

  B. 5 GB

  C. 10 GB

  D. 20 GB

  Correct Answer: C

  The Data Store Size. A minimum size of 256 MB is required for the data store. The default value is 10 GB.

• Question 47:

  When optimizing certain application protocols such as business continuity /data replication (BCDR) and Virtual Desktop Infrastructure (VDI), Riverbed often recommends the careful use of which network congestion algorithm?

  A. MXTCP

  B. SkipWare

  C. Bandwidth Estimation

  D. HSTCP

  Correct Answer: A

  Using Riverbed's unique MX-TCP functionality, combined with its Hierarchical Fair Service Curve (HSFC)

  QoS technology, users are simultaneously guaranteed bandwidth for their virtual desktop connections and

  some of the latency impact is mitigated. The results below show operational improvements for particularly

  common user actions; results will certainly vary based on use case and network design.

  Incorrect:

  not B: Riverbed SkipWare adds another layer of optimization to WAN satellite links that have up to 10

  times more latency than terrestrial WAN links. SkipWare users can be assured of the high performance,

  scalability, flexibility, and DoD standards compliance necessary to keep federal, military, and commercial

  satellite networks running at peak efficiency.

• Question 49:

  True or False? SteelHead SaaS can provide Netflow and SteelFlow to other Riverbed products to monitor and troubleshoot SaaS performance issues.

  A. True

  B. False

  Correct Answer: A

  *

  NetFlow is supported. To enable NetFlow on the Riverbed Steelhead appliance running RiOS v5.5.1 or

  RiOS v5.5.3, navigate to the Configure, Networking, NetFlow page and set the configuration.

  *

  All SteelHead appliances can send SteelFlow data to SteelCentral NetProfiler (free of charge): SteelFlow

  is a Riverbed-specific version of NetFlow that provides visibility into SteelHead QoS, response time, WAN

  optimization reporting, application visibility, and so on

  *

  Late last year [2014] Riverbed enabled deep integration between SteelHead and SteelCentral

  AppResponse.

  AppResponse lets you monitor the end-user experience for SteelHead-optimized web and SaaS

  applications.
