RiOS v7.0 and later, the packet-mode-optimization feature can: (Select 2)

A.

optimize TCP IPv6

B.

optimize UDP IPv6

C.

optimize UDP IPv4

D.

optimize TCP IPv4

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.

During an upgrade, what steps are necessary to convert VM slots for use in Steelhead EX v2.0? (Select 3)

A.

Transfer the slot to a remote server (or download from a browser).

B.

Convert the slot or package for use on a Steelhead EX v2.0 appliance and adjust its properties, if necessary.

C.

Configure the slots to not start before upgrading to Steelhead EX v2.0.

D.

Create compressed versions of your existing VSP slots.

E.

Any VM slots that do not use data flow will be automatically converted during the upgrade to Steelhead EX v2.0.

Which of the following methods can be used to reduce the load on a router configured to use outbound interface WCCP redirection? (Select 3)

A.

Using inbound interface redirection instead

B.

Use fixed-target rules and remove WCCP on the WAN facing interfaces

C.

Use Redirect lists to control what traffic gets redirected

D.

Use the router command “load interval 30” to restrict WCCP to use 30% of the CPU

E.

Use Event Element Manager (EEM) to load balance between a clustered Steelhead appliance deployment

When using Correct Addressing, what is the out-of-band (OOB) splice connection described as?

A.

A virtual connection contained within one of the inner-connections which corresponds to a client-server connection

B.

A separate connection between the Primary IP addresses of the client and server Steelhead appliances

C.

A separate inner-connection between two Steelhead appliances not directly related to any one of the user inner connections

D.

No such construct exists

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?

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

To prevent possible denial of service attack, such as TCP SYN flooding, which of the following features could be used?

A.

No TCP SYN Flooding

B.

Connection limit per source IP

C.

Limit UDP traffic

D.

Run Deep Packet Inspection on all traffic

E.

Run Deep Packet Inspection on TCP traffic only

Which of the following control messages are NOT used by WCCP? (Select 2)

A.

PEEK_A_BOO

B.

I_SEE_YOU

C.

REDIRECT_ASSIGN

D.

REMOVAL_QUERY

E.

KEEPALIVE

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.

What is the best way to resolve this issue?

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
