Cisco 644-068 Advanced Routing and Switching for Field Engineers – ARSFE Exam Practice Test

The architecture shows building blocks and abstract capabilities of a system and the relationships between the individual components.

The design shows concrete products, expected performance, and scalability options of a solution.

The design is the basis for creating the architecture.

The architecture includes a description of the best possible solution.

The exponential growth in bandwidth requirements and increased sensitivity to latency can be addressed by Cisco WAAS.

Transcoding services in a video and collaboration deployment can be provided in Cisco IOS software, so no hardware DSPs are required on the Cisco 3900 router series.

Cloud-based managed security is supported by the built-in ScanSafe Connector.

Cisco Unified Communications Manager Express can run on Cisco UCS Express.

Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS on SRE for ISR G2, WAASappliances, vWAAS, and WAAS PC.

Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS on SRE for ISRG2, WAAS appliances, and vWAAS.

Cisco WAAS can substantially reduce band requirements of Microsoft RDP, Citrix ICA, and PCoIP.

When using Microsoft RDP, make sure that you disable nativeRDP compression and encryption.

When testing or demonstrating WAAS performance with ICA, be aware that the bandwidth reduction increases with additional users. Traffic of a single user is reduced by 20 – 30%, while traffic of 10 users is reduced by 50 – 70%.

Cisco WAAS can provide about 20% compression ratio for watching videos over Microsoft RDP.

The SBA toolset includes Partner Enablement Assets and EcoPartner Guides.

SBA guides are available for enterprise deployments only.

CVDs are end-to-end designs which are well-tested and fully documented.

Gold partners have access to a demo lab for each validated design.

The Cisco Catalyst 6500 series is the better choice if the core is outside the data center.

The Cisco Nexus 7000 series is the better choice if rich WAN services are required.

The Cisco Catalyst 6500 series is the better choice if L2VPN is required.

Both, the Cisco Catalyst 6500 series and the Cisco Nexus 7000 series support NX-OScapabilities.
