質問 2：
Users report that CIFS transfer speeds from a domain member server are much faster than from a domain controller. The Current Connections report confirms that connections to the domain controller show a red warning triangle. What configuration steps are required to resolve this issue?
A. The client-side SteelHead should be joined to the domain in Workstation mode, enable CIFS SMB Signing and Transparent Mode.
B. Domain Controllers should not be used for file sharing as they are always slower than domain member servers.
C. The server-side SteelHead should be joined to the domain in Workstation mode, enable CIFS SMB Signing and Transparent Mode.
D. Both the client-side and server-side SteelHeads should be joined to the domain in Active Directory Integrated mode.
E. The server-side SteelHead should be joined to the domain in Active Directory Integrated mode, enable CIFS SMB Signing and Transparent Mode.
正解：D

質問 3：
You are using TCPdumps on the server-side SteelHead to troubleshoot an application connectivity issue. The following filter is used on the TCPdump:
(host <client IP> and host <server IP>) or (host <server IP> and host <steelheadinpath IP>) or (proto gre and ((ip[40:4] = <hex server IP> and ip[44:4] = <hex client IP>) or (ip[40:4] = <hex client IP> and ip[44:4] = <hex server IP>)) or (port 7850) What part of the filter captures the traffic which the Interceptor has applied NAT to?
A. (host <client IP> and host <server IP>)
B. (host <server IP> and host <steelhead inpath IP>)
C. (ip[40:4] = <hex client IP> and ip[44:4] = <hex server IP>)
D. (proto gre and ((ip[40:4] = <hex server IP> and ip[44:4] = <hex client IP>)
正解：C

質問 4：
In a WCCP configuration, during a packet trace, you notice the return WCCP communication on a CAT 6500 is using GRE. The Steelhead appliance is directly connected to it. What can be done to alleviate the router's CPU? (Select 2)
A. Force L2 return
B. Use peering rules to avoid using GRE altogether
C. Use NBAR to redirect
D. Use PBR
E. Nothing can be done to force traffic as a different return
正解：A,D

質問 5：
At the data center, two SteelHeads are deployed in parallel, configured with connection forwarding. They are both actively optimizing connections via inpath0_0 and the customer requires that optimization continues in the event of an appliance failure. Which features should be configured to provide the customer with optimization if an appliance fails? (Choose two.)
A. No in-path neighbor allow-failure
B. no asymmetric-route-detect enable
C. In-path neighbor allow-failure
D. interface inpath0_0 fail-to-bypass enable w-failure
E. no interface inpath0_0 fail-to-bypass enable
正解：C

質問 6：
What is the priority bit order for WCCP MASK?
A. Source IP, destination port, destination IP, source port
B. Source port, source IP, destination port, destination IP
C. Destination port, source port, destination IP, source IP
D. There is no priority order. It is weighted through bit assignments.
E. Source port, destination port, source IP, destination IP
正解：E

正解：A,B,C

質問 8：
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. Out-of-path
B. Hybrid Mode
C. C and D
D. WCCP/PBR
E. In-path
正解：B

質問 9：
On the Steelhead Mobile Controller, when should you use the CIFS option 'Disable Write Optimization'?
A. To increase performance during large updates to files
B. An application that expects write-through without asking for it explicitly
C. To increase performance during directory listings
D. When the Steelhead Mobile client does frequent writes to large files
E. To reduce datastore usage on busy Steelhead Mobile clients
正解：B
