Cisco Advanced Routing and Switching for Field Engineers – ARSFE 644-068 Exam Dumps: Updated Questions & Answers (September 2025)

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.

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.

A universal Cisco IOS image includes all software features; additional software features are then activated by license keys without changing Cisco IOS.

In order to obtain a license file, the product ID and serial number of the device are sent to the representative Cisco Channel Partner, along with the purchased product activation key.

Cisco IOS 15 is available in two trains: T, which includes bug fixes and new features, and M,which includes bug fixes only.

The Cisco ASR 1000 series features IOS-XE, a software architecture that consists of a platform component, IOS-XE middleware, andthe actual Cisco IOS software.

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.

All Cisco ISR G2 routers provide network automation, consolidated VPN, and security features.

The Cisco 800 and 1900 router series both offer entry-level application optimization features.

The Cisco 1900, 2900, and 3900 router series provide video and collaboration features.

The Cisco 2900 and 3900 router series support Cisco UCS Express.?

The Cisco 1900 router series supports Cisco Unified Communications Manager Business Edition 6000.

High availability?

Integrated services?

Network access control?

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.

Cisco Prime NAM platforms include WAAS virtual blade, Cisco NAM 2200 Series appliances, Cisco 6500 Series NAM blades, Cisco ISR G2 blades, and Cisco ISR G2 SRE.?

Cisco Prime NAM includes application performance analytics and provides application-specific information like round-trip time, client response time, and server response time.

The next-generation integrated service module for the Cisco Catalyst 6500 is Cisco Prime NAM-3. It supports up to 30 Gb/s traffic monitoring throughput.?

Data sources to Cisco Prime NAM include SPAN, ERSPAN, RSPAN, and Cisco WAAS.?

Cisco Prime NAM cannot collect data from Netflow and CEF
