• Question 21:

  What configuration policies can be used on the SteelCentral Controller for SteelHead (SCC) for Interceptor deployments?

  A. The SCC can be used to create all configuration for the Interceptors and its associated SteelHeads, as long as all the devices are in the same SCC group.

  B. The SCC can create in-path rules policies the same as a SteelHead, as long as that is the only page enabled for the Interceptor.

  C. The SCC can be used to configure the cluster of registered Interceptors and SteelHeads. Then, in-path rules and load balancing rules can be pushed to the interceptors.

  D. The SCC can be used to create cluster policies, for the Interceptor to SteelHead connections only and not in-path or load balancing rules.

  E. The SCC can only monitor the health, backup the configuration and upgrade Interceptors. Policies are only for SteelHeads. Interceptors and SteelHead Mobile are not supported.

  Correct Answer: C

• Question 22:

  Examine the diagram below. The customer needs to optimize data center servers and also servers within the DMZ but wants to keep the SteelHead behind the firewall. Which optimization mode would support this environment?

  

  A. Hybrid mode

  B. Virtual In-path mode

  C. WCCP or Interceptor mode

  D. Out-of-path mode

  E. In-path mode

  Correct Answer: A

• Question 23:

  You deploy a pair of SteelHead appliances in-path. At the server-side, there is a firewall inspecting traffic between the SteelHeads. The firewall must see the original client and server IPs and is configured to drop packets where the same host pairs and port pairs are reused within 30 seconds of termination. Which addressing mode would workaround this issue?

  A. Full Transparency

  B. Port Transparency

  C. Correct Addressing

  D. Full Transparency with reset

  Correct Answer: A

• Question 24:

  SteelHead SaaS is configured using the default redirection port. Which statement correctly describes the configuration that must be applied to a firewall at the branch location?

  A. Allow UDP 9545 from/to In-path interfaces

  B. Allow 443 traffic from/to Primary interface

  C. Allow TCP 9545 from/to In-path interfaces

  D. Allow TCP 9545 from/to Primary interfaces

  Correct Answer: A

• Question 25:

  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

• Question 26:

  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 27:

  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 28:

  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 29:

  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 30:

  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
