Which three network management requirements are common practices in network design? (Choose three)

• A. Ensure that all network devices have their clocks synchronized.
• B. Validate data plane health, and application and services availability, with synthetic traffic.
• C. Collect SNMP poll information for future regression analysis.
• D. Capture both ingress and egress flow-based packets, while avoiding duplication of flows.
• E. Look at average counters instead of instantaneous counters for inconsistent and bursty KPIs, such as CPU utilization and interface utilization.

Which solution prevents microloops from be formed during network convergence time?

• A. RSVP-TE
• B. Prefix suppression
• C. RLFA
• D. LFA

Which option reduces jitter in a VoIP network?

• A. Adjust the playout delay buffer at the receiver
• B. Increase the bandwidth of the links
• C. Deploy WRED
• D. Deploy call Admission Control

Refer to the exhibit.

You are designing a data center migration from one location to another, which requires all existing VLANs spanned to the new data center to maintain host IP addressing. Two temporary Gigabit Ethernet circuits are available to extend the VLANs at Layer 2 to the location as trunk links between core switches in each location.
Which solution provides maximum fault isolation between the two data centers to ensure a Layer Issue in one data center does not affect the other during the migration?

• A. Enable STP PortFast on host ports within each data center
• B. Perform HSRP filtering over the trunk links to maintain active HSRP gateways within each data center for each VLAN
• C. Perform BPDU filtering over the trunk links
• D. Run the dual links as multichassis Etherchannel trunk between core switches within each location
