With these default registry parameters, SMB signing is negotiated in the following manner. (Select 2)

A. SMB/CIFS exchanges between the Client/Workstation and the Member Server are not signed

B. SMB/CIFS exchanges between the Client/Workstation and the Member Server are always signed

Refer to the exhibit.

In the accompanying exhibit, SH3 and SH4 are able to optimize FTP and HTTP sessions between Client41 and the respective application hosts Server31 and Server32. However, optimization does not happen for Client42 and these application hosts. A quick check on SH3 and SH4 registers neither optimized nor pass-through traffic from Client42. Client42 is able to ping Client41 and the in-path address of SH4. Note that SH3 and SH4 are in auto-discovery mode. What is the likely cause?

A. The default gateway of Client41 is configured wrong

B. The default gateway of Client42 is configured wrong

C. The default gateway of SH3 is configured wrong

D. The default gateway of SH4 is configured wrong

E. The routing protocol between R3 and R4 is configured wrong

WCCP uses bits to create and distribute buckets. Using HASH assignment, what are the maximum number of bits used?

A. 4

B. 7

C. 8

D. 32

E. 256

When Connection Forwarding is in use, when a neighbor fails, the default behavior of the remaining neighbor will be to:

A. It will start to bypass traffic immediately

B. It will start to bypass traffic only after about 30 seconds

C. It is transparent to the outage and will continue to optimize as per normal

D. It will cease to optimize for about 30 seconds and start to optimize again

In the exhibit, there is a resident firewall inside the WAN cloud that drops packets with any TCP option. The customer allows you to use fixed-target rules instead. The firewall policy can only allow unassigned ports 7750-7751 to pass-through it. Additionally, the SH3 has been configured with service port 7750, while SH4 has been configured with service port 7751. Which of the following fixed-target rule specification is correct?

A. The fixed-target rule at SH4 peers to the inpath0_0 IP address of SH3 as the target appliance with port number 7800. The fixed-target rule at SH3 peers to the inpath0_0 IP address of SH4 as the target appliance with port number 7800.

B. The fixed-target rule at SH4 peers to the inpath0_0 IP address of SH3 as the target appliance with port number 7810. The fixed-target rule at SH3 peers to the inpath0_0 IP address of SH4 as the target appliance with port number 7810.

C. The fixed-target rule at SH4 peers to the inpath0_0 IP address of SH3 as the target appliance with port number 7750. The fixed-target rule at SH3 peers to the inpath0_0 IP address of SH4 as the target appliance with port number 7750.

D. The fixed-target rule at SH4 peers to the inpath0_0 IP address of SH3 as the target appliance with port number 7751. The fixed-target rule at SH3 peers to the inpath0_0 IP address of SH4 as the target appliance with port number 7750.

E. The fixed-target rule at SH4 peers to the inpath0_0 IP address of SH3 as the target appliance with port number 7750. The fixed-target rule at SH3 peers to the inpath0_0 IP address of SH4 as the target appliance with port number 7751.

B. It is a UDP connection.

C. The branch Steelhead appliance is down.

D. Services are not running on the branch Steelhead appliance.

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.
