  • A: The three most significant (first) bits define 8 forwarding classes.
  • B: The three least significant (last) bits of the DSCP specify the drop probability.
  • C: The full 8 bits of the TOS field are used for DSCP.
  • D: To convert DSCP to IP precedence, the three most significant (first) bits are matched.
  • E: DSCP provides for eight drop probabilities.

Question 5

  • A: DSCP value
  • B: 802.1p value
  • C: IP DF bit
  • D: TCP/UDP port numbers
  • E: HTML version number

Question 6
Which of the following are characteristics of DSCP? (Choose two)

  • A: DSCP is part of the Layer 3 header.
  • B: DSCP is a 6-bit field.
  • C: DSCP specifies eight different priorities.
  • D: DSCP specifies four precedence levels.
  • E: DSCP is part of the Layer 2 header
  • F: DSCP specifies 128 different per-hop behaviors.

Question 7
What is an SLA? (Choose two)

  • A: An SLA is used to provide automated, real-time testing and alarming for throughput, latency, and jitter across a provider's network.
  • B: An SLA is an agreement between a customer and a provider that dictates the treatment of customer traffic across the provider's network.
  • C: An SLA allows customers to control all traffic within the service provider's network by prioritizing their traffic over others as desired.
  • D: An SLA allows a customer to pre-mark traffic and ensure that traffic is treated as per the agreement within the provider's network.
  • E: An SLA is a standard set of network QoS policies that a provider shares to all its customers, allowing them to better understand the treatment of traffic within the provider's network.
