Correct answer: The server-side SteelHead has not been joined to the Active Directory domain.

Optimizing encrypted SMBv3 traffic requires the server-side SteelHead to participate in the Kerberos authentication process. To do this, it must be joined to the Active Directory domain in the correct mode (e.g., Active Directory Integrated). Without domain membership, the SteelHead cannot obtain the necessary session keys to decrypt, optimize, and re-encrypt the traffic, resulting in the connection being passed through without data reduction.

Correct answers: The DSCP marking on the outbound QoS rule.; The bandwidth allocation and priority level within the traffic shaping policy.

The DSCP mark tags the packet so that other network devices (routers, switches) can honor the priority level across the WAN. Ensuring the correct DSCP value (e.g., EF for Expedited Forwarding) is critical for end-to-end prioritization.

The traffic shaping policy on the SteelHead itself determines how bandwidth is allocated on the WAN link. The 'Real-Time' class must have a high priority and a guaranteed minimum bandwidth to ensure it is not starved by other traffic during congestion.

Correct answer: True

In a WCCP deployment, the router encapsulates redirected packets using GRE and sends them to the SteelHead's in-path IP address. The SteelHead then processes the traffic and sends it back to the router. For this communication to function correctly, the router and the SteelHead's in-path interface must be able to communicate at Layer 3, which typically requires them to be on the same IP subnet.

Correct answer: Upgrade the backup appliance first, allow it to reboot, then manually fail over and upgrade the former primary appliance.

The correct procedure for upgrading an HA pair is to upgrade the backup (standby) unit first. Once it has successfully rebooted with the new software version, you can initiate a manual failover. This makes the newly upgraded appliance the active primary. You can then proceed to upgrade the other appliance (now the backup) with minimal interruption to traffic, as one unit remains active throughout the process.

Correct answer: Verify the AWS VPC route tables are configured to direct traffic to the SteelHead-c's network interface.

In a cloud environment like AWS, routing is controlled by VPC route tables. For a SteelHead-c to intercept traffic, the route tables for the relevant subnets must be explicitly configured to send traffic destined for the on-premises network (or other targets) to the Elastic Network Interface (ENI) of the SteelHead-c instance. If this routing is incorrect, traffic will bypass the appliance entirely.

Correct answer: enabled

The `enabled` parameter configures the SteelHead to perform SMB signing on behalf of the server if the client requests it, even if the server itself does not support or require signing. This allows optimization to proceed while still satisfying the client's security requirement. `required` would force signing always, and `passthrough` would disable signing optimization.

Correct answer: Top Talkers Report

The Top Talkers report provides a breakdown of traffic by application, source/destination IP, and port. This allows an administrator to quickly identify which specific flows are generating the most traffic and, by extension, likely consuming the most CPU for optimization processing. This is more granular and actionable for this scenario than a general traffic summary.

Correct answer: Install the POS application server's actual private key and certificate onto the data center SteelHead cluster.

This is a classic use case for server-side private key SSL optimization. By installing the actual private key of the POS server onto the SteelHead, the appliance can decrypt the traffic for optimization without needing to forge a proxy certificate. Since the client (POS terminal) sees the original, unaltered server certificate, there is no need to install a new trusted CA on the client side, thus satisfying the security team's constraint.

Correct answer: An Application Group

Path Selection rules use Application Groups (or individual applications) to classify traffic. Riverbed provides pre-defined application signatures for common SaaS applications like Office 365. The administrator would select the 'Microsoft Office 365' application group as the match criteria in the path selection rule to direct this specific traffic.

Correct answer: To allow the backup SteelHead to take over existing optimized connections from the primary if it fails.

Connection Forwarding is the mechanism that allows for stateful failover. When enabled, the primary SteelHead synchronizes connection state information with the backup appliance. If the primary fails, the backup can take over and continue optimizing these existing connections without forcing them to be re-established, which minimizes disruption.
