• Question 32:

  You choose to deploy a Steelhead appliance logically in-path using policy-based routing (PBR) as the traffic redirection method. Additionally, you want to mark the Type of Service (ToS) value for active FTP as AF21 using route-maps. Which route-map specified Type of Service (ToS) value is correct? (Hint: Use the calculator)

  A. EF21
  B. 0x48
  C. 0x58
  D. 0xb8
  E. 18
  B. 0x48

• Question 33:

  A parallel SteelHead deployment between datacenters is being discussed by a customer and an Integrator. The customer would like to configure connection forwarding between the SteelHeads in two datacenters with 20 ms RTT between them. What would be the possible outcome, if the nearest branch SteelHead is 40 ms away?

  A. The latency between the Neighbor SteelHeads will mean that Connection Forwarding will not come up.
  B. All asymmetrically routed traffic will suffer from increased latency from the nearer branches.
  C. The Nagle algorithm timer can be adjusted so as to mitigate the symptoms from the closer branches.
  D. There will be little or no impact as it only affects the initial connection.
  E. Suboptimal performance only from HTTP traffic due to increased connection times.
  B. All asymmetrically routed traffic will suffer from increased latency from the nearer branches.

• Question 34:

  Which are true about the Steelhead appliance backups taken and stored by the CMC appliance? (Select 3)

  A. They are text file snapshots of the current running configuration taken at 3 a.m. (by default)
  B. The CMC appliance creates hyperlinks of the backups for easy viewing with a Web browser
  C. The configurations can be copied from the CMC appliance back to the Steelhead appliance via SCP
  D. There is a limit of five configurations per Steelhead appliance that can be stored at any one time in a rolling queue
  E. The Steelhead configuration files can be edited on the CMC appliance
  A. They are text file snapshots of the current running configuration taken at 3 a.m. (by default)
  B. The CMC appliance creates hyperlinks of the backups for easy viewing with a Web browser
  C. The configurations can be copied from the CMC appliance back to the Steelhead appliance via SCP

• Question 35:

  What of the following are true when deploying the Virtual Steelhead appliance? (Select 2)

  A. Only use 10 Gbps link
  B. Never reserve virtual CPU
  C. Do not over provision physical RAM
  D. Always use SSD drives
  E. Do not share physical NICs
  C. Do not over provision physical RAM
  E. Do not share physical NICs

• Question 36:

  You have a pair of SteelHead appliances, both deployed in-path, both have a valid IP address on the in-path interfaces, optimizations are enabled and the service is started. They are unable to auto discover each other as a firewall is stripping the probes. How could you work around this on the SteelHeads?

  A. Enable Enhanced Auto Discovery on each SteelHead and restart the optimization service.
  B. Create a full transparency in-path rule on each SteelHead.
  C. Use static NAT entries for each in-path interface.
  D. Create a fixed-target in-path rule on each SteelHead pointing to the peer in-path IP address on port 7810.
  E. Create a port transparency in-path rule on each SteelHead
  D. Create a fixed-target in-path rule on each SteelHead pointing to the peer in-path IP address on port 7810.

• Question 37:

  What is the supported redirection scheme/s used when a Steelhead appliance is in a WCCP deployment?

  A. GRE
  B. L2
  C. None
  D. Either GRE or L2
  D. Either GRE or L2

• Question 38:

  When troubleshooting a datastore wrapping alarm with 1 day wrapping notification configured, which of the following should be examined? (Select 2)

  A. If the unit was mis-sized
  B. If stream based encrypted traffic is being sent across the link as optimized
  C. If your fixed-target rules are pointing to the correct Steelhead appliance
  D. If Connection Forwarding was properly configured
  A. If the unit was mis-sized
  B. If stream based encrypted traffic is being sent across the link as optimized

• Question 39:
