• Question 161:

  Which of the following statements are true about server-side out-of-path deployments? (Select 4)

  A. They require no routing changes

  B. They require the use of WCCP or PBR for traffic redirection

  C. They hide the original client IP address from the server

  D. They require the use of a fixed-target rule on the client-side Steelhead appliance

  E. They require the use of either physical in-path or virtual in-path on the client-side Steelhead appliance

  Correct Answer: ACDE

• Question 162:

  A server-side logical in-path deployment is shown in the exhibit. Additionally, SH12 is configured with a fixed-target rule pointing to SH11. The client behind SH12 will not be able to establish a connection to SERVER1 as a logical loop will occur when the number of optimized connections in SH11 has reached the maximum system limit.

  

  What is the best way to resolve this issue?

  A. Use the largest Steelhead appliance model

  B. Enter the "in-path loopguard enable" command

  C. Use more than one Steelhead appliance

  D. Limit the number of TCP connections to be optimized

  E. Put SERVER1 in a different subnet from SH11

  Correct Answer: E

• Question 163:

  Refer to the exhibit.

  

  The customer would like to prevent a "black-holing" situation when using PBR when SH11 goes down. The Steelhead appliances are directly connected to the routers. What options are available to determine state level status of the Steelhead appliance? (Select 3)

  A. CDP

  B. NBAR

  C. Interface Tracking

  D. HTTP

  E. ICMP

  Correct Answer: ACE

• Question 164:

  How can you enable SkipWare?

  A. SkipWare is enabled automatically when the license is installed.

  B. On the Management Console host settings menu.

  C. SkipWare is enabled by default.

  D. On the Management Console high-speed TCP menu.

  Correct Answer: A

• Question 165:

  Select the command needed to add support for virtual in-path to your Steelhead appliance so that you can use WCCP or PBR with a Steelhead appliance.

  A. in-path inpath0_0 enable

  B. in-path oop enable

  C. ip virtual enable

  D. in-path virtual enable

  E. in-path wccp_pbr enable

  Correct Answer: B

• Question 166:

  To prevent possible denial of service attack, such as TCP SYN flooding, which of the following features could be used?

  A. No TCP SYN Flooding

  B. Connection limit per source IP

  C. Limit UDP traffic

  D. Run Deep Packet Inspection on all traffic

  E. Run Deep Packet Inspection on TCP traffic only

  Correct Answer: B

• Question 167:

  When two or more Steelhead appliances are configured with Connection Forwarding in such environments as WCCP clustering, what feature will allow remaining Steelhead appliances to continue to provide optimization for new connections when one unit fails?

  A. In-Path Neighbor FailurE. Allow

  B. WCCP neighbor active

  C. Minimum cluster count set to 1

  D. Maximum cluster count set to 2

  E. This cannot be done on Steelhead appliances

  Correct Answer: A

• Question 168:

  A customer wants to optimize traffic from remote VPN sites to DMZ servers in the data center shown in the accompanying exhibit.

  

  The customer would also like to deploy their data center Steelhead appliance in a way that would allow them to keep transparency to the LAN servers, and allow the LAN servers to initiate optimized connections to remote sites. The current network architecture can satisfy these requirements by using which following deployment method?

  A. In-path

  B. Out-of-path

  C. WCCP/PBR

  D. Hybrid Mode

  E. C and D

  Correct Answer: D

• Question 169:

  Hybrid Mode can best be defined as a combination of:

  A. Physical in-path and WCCP

  B. Physical/virtual in-path and server-side out-of-path

  C. Physical/virtual in-path and PBR

  D. A and B

  E. A, B, and C

  Correct Answer: B

• Question 170:

  The Primary interface is REQUIRED for which deployment methods and features?

  1) In-path 2) Server-side out-of-path 3) Logical in-path (WCCP/PBR) 4) Hybrid Mode 5) Proxy File Services (PFS)

  A. 2

  B. 1, 2

  C. 2, 3

  D. 2, 4
