  Which section of the Steelhead appliance Management Console can help identify speed/duplex errors? (Select 2)

  A. View Logs

  B. Current Connections

• Question 224:

  A customer with a new physical in-path installation decides to turn on the optimization service during lunch time on a working day. This is done so that he can see if the users perceive any performance improvement. When starting the optimization service, he does not enable the in-path kickoff option. Assuming there were several already active connections when he starts the optimization service, how will the Steelhead appliances handle these existing connections?

  A. The Steelhead appliance will optimize all connections, including pre-existing

  B. The Steelhead appliance will pass-through all pre-existing connections, leaving them un-optimized

  C. The Steelhead appliance will reset all pre-existing connections, thus automatically changing their optimization status from un-optimized to optimized

  D. The Steelhead appliance will list the connections as "pre-existing" on the Current Connections page

  E. Both B and D

  F. Both C and D

  Correct Answer: E

• Question 225:

  A customer is reporting higher than normal CPU utilization on certain routers in their network. Looking at their Steelhead appliance logs, they see "intercept/localkernel/icore.c:1463] nat_check: SYN packet for already NAT'd connection 100.100.100.33:1611 -> 100.200.200.32:80 ==> 100.201.201.25:7801". All connections are showing up optimized but the logs persist. Given the exhibit,

  

  what is the likely problem?

  A. Lost Opportunistic Lock

  B. SMB Signing

  C. Fixed-target rule is needed

  D. Asymmetric Route

  E. Packet Ricochet

  Correct Answer: E

• Question 226:

  Refer to the exhibit.

  

  A customer is reporting that the first connection from a user to the server is failing. However, subsequent connections work properly and are optimized. How can this problem best be resolved?

  A. Fixed-target rule

  B. Enable RIP/OSPF on the routers

  C. Enable Simplified Routing

  D. Enable QoS

  E. Enable RIP/OSPF on the Steelhead appliances

  Correct Answer: C

• Question 227:

  In an existing deployment, all connections appear to be unoptimized. The Current Connections page lists the connections as pass-through.

  

  The logs indicate admission control "Jan 19 18:44:56 client sport[343]: [admission_control.WARN] Pausing intercept." What are some possible ways to alleviate the problem? (Select 2)

  A. Verify that there is no SMB Signing on the server

  B. Ensure that there are no Opportunistic Lock issues

  C. Disable or reduce the connection timeout of MAPI prepopulation

  D. Investigate if there is a virus on a client trying to propagate itself

  E. Validate that NFS v2 broadcasts are enabled

  Correct Answer: CD

• Question 228:

  In a recent in-path deployment, users are complaining that some of their CIFS drive-mapping connections do not appear to be optimized. Upon further analysis, you discover the file shares reside on a domain controller. The Steelhead appliances are deployed in a default configuration. Which of the following is the most likely cause of the problem?

  A. The Steelhead appliance lost an Opportunistic Lock on the file

  B. SMB Signing is set to required

  C. No fixed-target rules installed

  D. Misconfigured Steelhead appliance

  E. Packet ricochet

  Correct Answer: B

• Question 229:

  You have an in-house HTTP application running on port 8443 but you are not seeing HTTP optimization. You checked and made sure that the HTTP blade is enabled. What is the likely problem?

  A. Primary port needs to be on the LAN side of the Steelhead

  B. There is a separate license key for the HTTP blade

  C. The HTTP blade will only work on port 80 and 8080 and can not be changed

  D. The HTTP blade only supports HTTP 1.1 and the application is using HTTP 1.0

  E. HTTP blade is enabled by default on port 80 and 8080. An in-path rule is necessary for all other ports.

  Correct Answer: E

• Question 230:

  Refer to the exhibit.

  

  Traffic going from Corp-A-DC-2 towards Corp-B will always use Link-1. Traffic from Corp-B back to CorpA-DC-1 may traverse Corp-A-DC-1, over the GigaMAN before it reaches Corp-A-DC-2. No TCP connections are initiated from Corp-B to either Corp-A-DC-1 or Corp-A-DC-2. Unfortunately, the customer does not have any money to purchase any additional Steelheads. What are some possible fixes to ensure optimization occurs while Link-1 is operational? (If Link-1 ceases to function, optimization is not possible.) (Select 2)

  A. Configure a fixed-target rule on the Corp-A-DC-2 Steelhead pointing to the Corp-B Steelhead on port 7800

  B. On the Corp-B Steelhead, enable "in-path probe direct"

  C. On the Corp-A-DC-2 Steelhead, enable "in-path probe direct"

  D. Configure the Corp-A-DC-2 Steelhead to inject a route into the network

  E. Enable Full Transparency

  Correct Answer: AC
