A financial services firm has deployed SteelHead appliances between its New York headquarters and a London branch office. They are optimizing CIFS traffic for accessing large financial models. After deployment, users report that while initial access to a file is slow, subsequent access to the same file by other users is significantly faster. However, if a small change is made to a large file, the entire file seems to be re-transmitted over the WAN. Which RiOS feature is most likely misconfigured or not being fully utilized?

A network architect is designing a SteelHead deployment for a large enterprise with a complex, multi-vendor router environment. To ensure resilience and avoid creating a single point of failure, they want to redirect traffic to a cluster of SteelHead appliances without modifying client configurations or using Policy-Based Routing (PBR). Which deployment method is best suited for this requirement?

A system administrator is deploying a Virtual SteelHead (VSH) appliance on a VMware ESXi host that also runs several other critical business applications. To guarantee a minimum level of performance for WAN optimization, the administrator needs to ensure the VSH virtual machine receives a consistent amount of CPU resources, even when the host is under heavy load. Which VMware feature should be configured for the VSH virtual machine?

True or False: When using SteelHead Mobile with the 'Branch Warming' feature enabled, the SteelHead Mobile client's datastore is synchronized only with the server-side SteelHead appliance, not the local branch SteelHead appliance.

A company has deployed SteelHead CX appliances to accelerate access to their SaaS applications, including Microsoft 365. An administrator needs to ensure that only authenticated Microsoft 365 traffic from their company's tenant is optimized, while blocking optimization for personal Microsoft 365 accounts. Which feature within the SteelHead CX configuration should be used to achieve this?

During a network audit, it was discovered that a SteelHead appliance, configured for SSL optimization, is using a server certificate with a weak signing algorithm (SHA-1). To comply with new security policies, the certificate must be replaced with one using SHA-256. What are the critical steps an administrator must perform on the SteelHead to update the SSL certificate for a specific internal server? (Select TWO)

A consultant is reviewing a SteelHead deployment where two appliances are connected over a satellite link characterized by very high latency (>600ms) and moderate packet loss. Standard TCP applications are performing poorly despite data reduction ratios being high. The consultant suspects the TCP congestion control algorithm is too conservative for this link type. Which Riverbed-specific transport streamlining feature is designed specifically to address this kind of challenging network environment?

A network administrator needs to create a QoS policy on a SteelHead appliance to prioritize interactive SSH traffic over bulk FTP data transfers. The goal is to ensure SSH sessions remain responsive even when large files are being transferred. To which predefined QoS class should the SSH traffic (TCP port 22) be assigned to give it higher priority?

An administrator is managing a large-scale SteelHead deployment using a SteelCentral Controller (SCC). A new security policy requires that all administrative access to the SteelHead appliances must use a centralized authentication system. The administrator configures the SCC to push a policy that sets the authentication mode to RADIUS. However, several appliances in a remote region fail to apply the new policy. What is the most likely reason for this failure?

**Case Study:** A global architectural firm, "ArchiDesign," has its primary data center in Chicago, with branch offices in London, Singapore, and Sydney. The firm relies heavily on transferring large Autodesk Revit (CAD) files and uses a centralized document management system over CIFS/SMB. All inter-office traffic is sent over a managed MPLS network, but users in the APAC region (Singapore and Sydney) complain about extremely slow file transfers and application response times due to high latency (250-300ms). **Current Situation:** The network team has deployed SteelHead appliances at all four locations. Data reduction ratios are excellent (averaging 85%), but the application-level performance improvement for the APAC offices is still below expectations. The network team has validated that the issue is not bandwidth saturation but rather the number of TCP round trips required by the applications across the high-latency links. **Requirements:** - Significantly improve the 'time-to-first-byte' for users opening large CAD files. - Reduce the chattiness of the CIFS/SMB protocol over the WAN. - The solution must not require any changes to the end-user workstations or the servers in Chicago. Which combination of RiOS features should the ArchiDesign network team focus on configuring and optimizing to best meet these requirements?
