Riverbed Riverstone Certification 199-01 Questions & Answers

• Question 11:

  You have a client and server using SMB2 signing. You have SMB optimization enabled on your SteelHeads, but SMB signing is not enabled on the server-side SteelHead. What is the effect on this on an SMB connection which the SteelHeads attempt to optimize?

  A. Any SMB2 connections between this client and server will be shown as optimized with protocol errors. No latency optimization or data reduction can be performed.

  B. SMB2 connections between this client and server, which are initiated at the client side will be fully optimized with latency reduction.

  C. Any SMB2 connections between this client and server will be optimized using data reduction only. No latency optimization will take place.

  D. Any SMB2 connections between this client and server will be optimized using latency optimization only No data reduction will take place.

  Correct Answer: C

• Question 12:

  When optimizing applications that open many short-lived HTTP connections, which operating mode will give the best performance?

  A. Full Transparency

  B. Full Transparency with reset

  C. Correct Addressing

  D. Port Transparency

  E. Any of the above, because performance is not affected by these

  Correct Answer: C

• Question 13:

  If data store synchronization is to be successful, which of these must be true?

  A. There must be a resilient path between the SteelHeads to prevent a split brain situation.

  B. The in-path IP addresses must be reachable from each other and connected physically in-path.

  C. The SteelHeads must be the same model and run the same RiOS version.

  D. The master must be the same or larger data store than the backup.

  E. The SteelHeads must be in a serial cluster arrangement.

  Correct Answer: B

• Question 14:

  True or False? To be able to use Active Directory assignments, the SteelCentral Controller for SteelHead Mobile must be joined to the domain.

  A. True

  B. False

  Correct Answer: A

• Question 15:

  A SteelHead blocks all traffic when the appliance is powered off. What reasons could cause this behavior? (Choose two.)

  A. This behavior is by design.

  B. Router, switch and SteelHead interfaces have auto MDI/MDIX but incorrect cables have been used.

  C. Fail-to-block is enabled.

  D. The bypass NIC battery has failed.

  E. Router, switch and SteelHead interfaces are hard coded and incorrect cables have been used.

  Correct Answer: BC

• Question 16:

  A SteelHead is deployed on an 802.1Q trunk in the diagram below. A connection is being optimized from a client on VLAN 20 using Correct Addressing.

  Which VLAN ID will be on the inner channel connection?

  

  A. 10

  B. 20

  C. The native VLAN

  D. No VLAN ID

  E. Only VLAN 10 can be optimized. All other are passed through on their original tag

  Correct Answer: B

• Question 17:

  In the SteelHead Mobile client application, the Connection List shows a connection with a green arrow. What does this indicate?

  A. A branch warning optimized connection

  B. A branch mode optimized connection

  C. An unlicensed connection

  D. A pass-through connection

  E. A normal optimized connection

  Correct Answer: B

• Question 18:

  Which option below best describes the WCCP redirection supported by a SteelHead?

  A. Ports Mode

  B. GRE only

  C. PBR

  D. GRE or L2

  E. L2 only

  Correct Answer: D

• Question 19:

  A user downloads a Microsoft Excel document from a server over an optimized connection. The transfer is very fast. The user makes some changes to the spreadsheet and then saves the document. The transfer is very slow. The user edited a Word document shortly before but that downloaded and saved at the same fast speeds. What happened to the Excel document?

  A. Microsoft Excel compresses and encrypts the data by default when saving Microsoft Excel data does not perform well for LZ compression and will always be slow.

  B. Microsoft Excel compresses the data by default when saving.

  C. Microsoft Excel reorders the entire data stream when it saves so it is now new (cold) data to the SteelHead.

  D. Microsoft Excel encrypts data by default when saving.

  Correct Answer: B

• Question 20:

  A recently installed branch SteelHead is successfully optimizing connections inbound from other locations. However, users report that their connections originating from that branch don't seem to be any faster and the Current Connections report shows their connections to be in pass-through. In-path rules correctly specify that auto-discovery should occur. What might be the problem?

  A. Simplified Routing should be enabled.

  B. There is asymmetry in the network.

  C. The optimization service on the branch SteelHead is not running.

  D. There is a duplex mismatch on the LAN port.

  E. The SteelHead LAN and WAN ports have been wired in reverse.

  Correct Answer: E
