Question 2
Which of the following are characteristics of 802.1p? (Choose two)
- 802.1p adds 16 bits to the Layer 2 header,
- 802.1p adds 16 bits to the Layer 3 header.

- 802.1p uses a field in the 802.1Q header.
- 802.1p uses a field in the Layer 3 IP header
- 802.1p defines a 3-bit Class of Service field.
Correct answer: DF
Question 3
Which of the following BEST describes a SAP when regarding QoS?
- A point in the network where EXP bits can be mapped to one of eight predefined FCs, each one with its own queue.
- A logical point in a service tunnel where all of customer traffic is aggregated.
- A point at which the initial classification of customer traffic occurs.
- A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).
- A point in the network where traffic flows from multiple different services are queued together, based on forwarding class.
Correct answer: C
Question 4
Individual application streams are considered microflows, whereas __________ are considered macroflows.
- SAPs
- SDPs
- Services
- Queues
- Schedulers
- Forwarding classes
Correct answer: F
Question 5
Which of the following are possible criteria for classifying packets at the network port ingress on the Nokia 7750 SR? (Choose three)
- The EXP bits in the MPLS header.
- The packet's source and destination IP addresses.
- The packet's DSCP bits.
- The dot1p bits in the frame header.
- The ID of an SDP that is transporting the packet.
Correct answer: ACD
Question 6
A default network policy is applied to all router interfaces associated with network ports.
- TRUE
- FALSE
Correct answer: A
Question 7
Which of the following are NOT ingress matching criteria for a network policy? (Choose two)
- TCP port numbers
- LSP EXP
- DSCP
- Source and destination IP addresses

Correct answer: AD
Question 8
Click the exhibit button below. A partial SAP-ingress policy configuration is shown below. A UDP video stream is sent to a PC with IP address 192.168.1.100. Given the SAP-ingress policy, to which forwarding class is the traffic matched?
- AF
- EF
- H2

On a Nokia IOM 3, how is buffer memory allocated per forwarding complex?
- 512 MB ingress, 512 MB egress
- 256 MB ingress, 256 MB egress
- 1 GB dynamically allocated between ingress and egress.
- 768 MB dynamically allocated between ingress and egress.
- 768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.
Correct answer: D
