644-068 Exam Dumps - Cisco Wireless LAN Questions and Answers

Cisco MediaNet Performance Monitor collects performance metrics of video traffic as flexible netflow records which can be processed by any netflow collector, such asCisco Prime Assurance Manager.

Cisco MediaNet supports only SNMP traps but not syslog messages.

When using PVDM3 on Cisco ISR G2, video streams of the same type can be locally mixed within the router. Video transcoding servicesrequire a dedicated video MCU.

Cisco MediaNet Mediatrace allows real-time troubleshooting by providing details about every hop of the end-to-end path of your mediastream.

Port security prevents MAC address flooding.

DHCP snooping prevents rogue DHCP servers from being placed on the network.

IP Source Guard prevents ARP spoofing attacks.

Private VLAN preventsclient to client communication.

MACsecprovides end-to-end encryption.

3G, 4G, and satellite connections are commonly used as backup links in high-end branches.

The standard branch typically uses MPLS as a primary link and any kind of Internet link(DSL, cable, etc.) for backup.

HD video traffic is found in high-end and ultra high-end branches.

WAAS Express is the preferred WAN optimization implementation in mobile and standard branches.

Understand the business objectives, current environment, and pain points of the customer.

Assess the current infrastructure, financial data, and operational management capabilities.

Identify configuration flaws on individual devices.

Analyze collected data, identify potential savings, and develop TCO and ROI.

Deliver business case documentation, detailed technical solution scenarios, and TCO report.

The Cisco Catalyst 3560 v2 and CiscoCatalyst 3560-X are stackable.

The Cisco Catalyst 3750 v2 and CiscoCatalyst 3750-X are stackable.

The Cisco Catalyst 2000 series support 802.1X and MACsec encryption.

The Cisco Catalyst 2000 series support PoE and PoE+, but they do not support 60 W per port like the Cisco Catalyst 3000and Cisco Catalyst 4000 series.

In order to receive priority treatment for mission-critical traffic across the SP cloud, the higher number of locally used classes of service have to be mapped to the fewer number service classes that are usually offered by service providers.

In order to maintain DSCP values end-to-end, inbound traffic from the SP cloud needs to be reclassified if it was sent through a tunnel.

RFC 4594 describes how to classify and mark traffic at the campus and branch LAN using 12 different classifications.

According to RFC 4594, voice and video traffic should be sent through two separate priority queues.

All WAE appliance models support inline deployment. Fail-to-wire capabilities ensure that traffic continues to flow through the system in case of ahardware or software failure.

Off-path interception of traffic can be achieved by policy-based routing or WCCP v2 interception.

Cisco WAAS Express supports off-path interceptiononly via WCCP v2 interception.

WAE appliances do not support 802.1Q.
