A. Duplex mismatch on either the LAN or WAN interfaces or both

B. Asymmetric Routing

C. Link speed mismatch on either the Primary or AUX interface

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

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

Correct Answer:A

Question 58

- (Exam Topic 1)

Question 59

- (Exam Topic 3)
When optimizing certain application protocols such as business continuity /data replication (BCDR) and Virtual Desktop Infrastructure (VDI), Riverbed often recommends the careful use of which network congestion algorithm?

A. MXTCP

B. SkipWare

C. Bandwidth Estimation

D. HSTCP

Correct Answer:A
Using Riverbed’s unique MX-TCP functionality, combined with its Hierarchical Fair Service Curve (HSFC) QoS technology, users are simultaneously guaranteed bandwidth for their virtual desktop connections and some of the latency impact is mitigated. The results below show operational improvements for particularly common user actions; results will certainly vary based on use case and network design.

Question 60

- (Exam Topic 3)
The CIFS latency optimization feature provides which performance benefits? (Choose two.)

A. Read-ahead and write-behind optimizations

B. Data reduction over the WAN

C. Latency reduction through transaction prediction

D. Data encryption over the WAN

Correct Answer:BC
CIFS optimization focuses on reducing the impact of WAN round-trip latency of common application and system behavior.
RiOS can perform full latency and bandwidth optimization securely for SMB signed traffic. References:
