1. Explain the two ways to measure the round trip transaction response time?
    There are two ways to measure the round trip transaction response time experienced by end users: passive and active.

    Passive monitoring involves deploying agents on desktops at the end user's location. These agents watch events or packets without slowing down the transaction.

    Active measurement involves simulating transactions (synthetic transaction) from a designated machine at defined interval.
  2. Which one would you use to obtain a 24*7 server application response time report?
    Use active measurement (or Synthetic Transactions) to obtain a 24/7 server application response time report as it does not require a user to be present.
  3. Describe how synthetic end-user monitoring works.
    Synthetic end user monitoring is a type of active monitoring that continuously monitor user experience using transactions generated by programs that exercise the application server in the same manner as an end-user or application client.
  4. List some of the benefits of synthetic end-user monitoring.
    • Benefits:
    • Monitor internal (behind the firewall)
    • customer-facing ¬†
    • cloud-based applications.

    Monitor and provide insight into problem for each individual steps that makes up a complete transactionAble to simulate users accessing from multiple locations 24 hours a day.
  5. Describe how Cisco IP SLA works and list some of its benefits.
    Service Level Agreement (SLA)s are written agreements between a service provider and their customers on the expected performance level of network services. SLAs offer the customer the ability to hold their network provider accountable for meeting service levels.

    Commonly used SLA metrics include:

    • Availability
    • Response time
    • Mean-time-to-repair (MTTR)
    • Packet loss
