Questions # 31:

When implementing WCCP, a Steelhead appliance is connected using which Steelhead appliance interface for optimization?

Options:

lan0_0

wan0_0

Primary

AUX

Remote

Answer

Questions # 32:

Which SteelHead Mobile feature can dynamically disable client optimization when in an office equipped with a local SteelHead?

Options:

Location Awareness

Data store synchronization

Fixed-target rules

Branch Warming

E, Connection Forwarding

Answer

Explanation

Location awareness enables SteelHead Mobile to detect that it is in a branch office with a SteelHead, and it enables the SteelHead to optimize SteelHead Mobile traffic.

Questions # 33:

When deploying a SteelHead on an 802.1Q trunk, which one of the following statements is true?

Options:

Simplified routing must be disabled.

The in-path interface must be configured on the native VLAN.

The VLAN tag on which the in-path interface is configured is the only subnet which will be optimized.

All optimized traffic will be sent on the in-path VLAN tag unless full transparency is enabled.

802.1Q trunks are only supported on the Interceptor appliance.

Answer

Explanation

A SteelHead can be deployed physically in-path on an 802.1Q trunk link, and can optimize connections where packets have been tagged with an 802.1Q header.

If correct addressing or port transparency is used, the SteelHead uses the configured in-path VLAN ID when transmitting packets towards the WAN. When using the full address transparency WAN visibilitymode, SteelHeads maintain the VLAN ID (along with IP address and TCP ports) when transmitting packets on the WAN side of optimized connections.

Questions # 34:

Data store synchronization takes place over which interface or interfaces?

Options:

Primary or Aux

Wan0_0

Remote

Inpath0_0

Lan0_0

Answer

Explanation

The traffic for RiOS data store synchronization is transferred through either the Steelhead appliance primary or auxiliary network interfaces, not the in-path interfaces.

Questions # 35:

When optimizing protocols such as signed SMB or encrypted MAPI, which of the following is true?

Options:

Special configuration is always necessary on the Domain Controller.

The server-side StealHead must be joined to the domain.

The domain administrator password must be made available to the SteelHead.

The client-side SteelHead must be joined to the domain.

Answer

Explanation

The server-side Stealhead appliance must be joined to the Windows Domain in order to Enable SMB Signing or to enable encrypted MAPI.

Questions # 36:

What Steelhead appliance interface must be connected in order to peer with the Interceptor appliance for optimization?

Options:

Primary

WAN

LAN

AUX

Console

Answer

Questions # 37:

If the Steelhead Mobile client optimization is being blocked by the client firewall, you must set which port on the client firewall to allow incoming traffic?

Options:

7744

7800

7801

7810

7820

Answer

Questions # 38:

You have noticed that your connections through the Steelhead appliance are slower than without it. All TCP connections show as optimized in the web interface. You are also experiencing intermittent connectivity and periodic file errors.

Of the following, what could be the most likely cause of this slowdown?

Options:

Duplex mismatch on either the LAN or WAN interfaces or both

Asymmetric Routing

Link speed mismatch on either the Primary or AUX interface

Packet ricochet is causing packets to consume bandwidth through the In-path interface

Memory corruption has caused buffer overflow on write I/O to SDR on disk

Answer

Questions # 39:

Which forms of administrative authentication are supported by the Steelhead appliances?:(Select 3)

Options:

NTLM

TACACS+

RADIUS

Kerberos

Local username and password

Answer

B, C, E

Questions # 40:

When performing datastore synchronization between two Steelhead appliances, segments of data are exchanged between them. Which interfaces can be used for datastore synchronization? (Select 2)
