Cisco 300-640 Value Pack (Frequently Bought Together)

During validation testing, an engineer observes microbursts causing packet drops on GPU uplinks. Which monitoring capability best detects short-duration congestion events?

• A. Streaming telemetry with high-frequency sampling
• B. Daily syslog review
• C. NetFlow with hourly exports
• D. Manual CLI inspection once per week

An engineer made changes to the corporate DNS, which caused a Cisco UCS X-Series domain to lose connectivity to Intersight. To restore connectivity, the management interface DNS and NTP settings must be updated using the device console UI. Which configuration change must be made in Intersight to allow the updated DNS configuration to persist?

• A. Edit the IMC access policy associated to the fabric interconnects.
• B. Edit the domain profile deployed to the fabric interconnect.
• C. Create a device connector policy and apply it to the blade chassis.
• D. Create a network connectivity policy and apply it to the blade chassis.

A data center administrator for a medium-sized manufacturing facility uses Intersight to perform unattended operating system installation on already discovered X-Series servers with server profiles assigned. Which set of prerequisites must be met for installing an operating system on a server in Cisco Mode?

• A. adding an OS image to the software repository
  adding an operating system configuration file to the software repository
• B. adding an OS image to the software repository
  adding a server configuration utility to the software repository
• C. configuring a firmware policy
  adding an operating system configuration file to the software repository
• D. configuring a virtual KVM policy
  adding a server configuration utility to the software repository

A Cisco Nexus switch is configured with QoS policies for AI traffic. Which scheduling mechanism guarantees bandwidth for critical traffic classes during congestion?

• A. FIFO
• B. Weighted scheduling
• C. Port mirroring
• D. MAC filtering

Which set of statements describes Quantized Congestion Notification?

• A. Explicit Congestion Notification reacts first to mitigate congestion, and Priority Flow Control acts as a fail-safe to prevent traffic drops if Explicit Congestion Notification is insufficient.
  A congestion notification packet sent toward the source by a host in response to receiving Explicit Congestion Notification with congestion experienced bits set.
• B. Explicit Congestion Notification reacts first to mitigate congestion, and Priority Flow Control acts as a fail-safe to prevent traffic drops if Explicit Congestion Notification is insufficient.
  A congestion notification packet sent toward the source by hosts and the network switch in response to receiving Explicit Congestion Notification with congestion experienced bits set.
• C. Priority Flow Control reacts first to mitigate congestion, and Explicit Congestion Notification acts as a fail-safe to prevent traffic drops if Priority Flow Control is insufficient.
  A congestion notification packet sent toward the source by a network switch in response to receiving Explicit Congestion Notification with congestion experienced bits set.
• D. Priority Flow Control reacts first to mitigate congestion, and Explicit Congestion Notification acts as a fail-safe to prevent traffic drops if Priority Flow Control is insufficient.
  A congestion notification packet sent toward the source by hosts and the network switch in response to receiving Explicit Congestion Notification with congestion experienced bits set.
