In the exhibit,

830-01 Question 82

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?

Options:
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.

Questions 83

When using Correct Addressing, without Enhanced Auto-discovery (EAD), what is the size of the probe response in the return SYN/ACK packet from the server-side Steelhead appliance?

Options:
A.

4 bytes

B.

10 bytes

C.

14 bytes

D.

18 bytes

E.

32 bytes

Questions 84

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.

830-01 Question 84

What is the best way to resolve this issue?

Options:
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

Questions 85

A customer wants to mark the IP precedence value for a passive FTP data connection as flash (flash = CS3). Which of the following are true? (Hint: Use the calculator)

Options:
A.

Specify qos dscp rule at client-side Steelhead appliance with a dest-port of 20 and with a DSCP value of 23

B.

Specify qos dscp rule at client-side Steelhead appliance with a dest-port of 20 and with a DSCP value of 24

C.

Specify qos dscp rule at server-side Steelhead appliance with a dest-port of 20 and with a DSCP value of 26

D.

Specify qos dscp rule at client-side Steelhead appliance with a dest-port of 20 and with a DSCP value of 26

E.

Specify qos dscp rule at server-side Steelhead appliance with a dest-port of 20 and with a DSCP value of 24

Questions 86

5) Proxy File Services (PFS)

Options:
A.

2

E.

2, 4, 5

Questions 87

You are configuring HighSpeed TCP in an environment with an OC-3 (155Mb/s) and 60 milliseconds of round-trip latency. You know that the rule of thumb is to set the Steelhead appliance's WAN Default Send Buffer Size and WAN Default Receive Buffer Size to 2*BDP for the link. The buffer size setting for this link would be closest to: (Hint: Use the calculator)

Options:
A.

4,665,000 bytes

B.

9,330,000 bytes

C.

3,110 bytes

D.

6,220 bytes

E.

2,325,000 bytes

Questions 88

In a Steelhead appliance deployment, the customer decides to use Full Transparency and block all incoming/outgoing TCP connections on port 7800 on their firewall. However, they are finding all TCP connections are passing through the Steelhead appliances (even ones that should be optimized via the in-path rule set).

If Full Transparency uses the original IP addresses and TCP ports for inner connections, what is the most likely cause of all TCP connections passing through the Steelhead appliances?

Options:
A.

The OOB (out-of-band) splice connection cannot be made

B.

The user connections (if using the same ephemeral TCP port) are blocking each other, since the Steelhead appliance had to make all of these sequentially

C.

Full Transparency is only supported on Steelhead 3U appliances

D.

All connections are being blocked by the firewall

Questions 89

Which of the following custom TACACS+ attribute-value (AV) pairs gives the user administrative privileges?

Options:
A.

local-user-name=superuser

B.

local-user-name=admin

C.

local-user-name=administrator

D.

local-user-name=monitor

E.

local-user-name=guest

Questions 90

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)

Options:
A.

Force L2 return

B.

Use PBR

C.

Use peering rules to avoid using GRE altogether

D.

Use NBAR to redirect

E.

Nothing can be done to force traffic as a different return
