第8题:
Out-of-profile packets are queued.
It causes TCP retransmits.
Marking and remarking are not supported.

It uses a single- and two-bucket mechanism for metering.
第9题:
Voice carrier stream utilizes Real-Time Transport Protocol (RTP) to carry the audio/media portion of the VoIP communication.
Voice traffic data flow involves large volumes of large packets.
Because a packet loss involves a small amount of data, voice traffic is less affected by packet losses than traditional data traffic is.
Voice packets are encapsulated in TCP segments to allow for proper sequencing during delivery.
Voice packets are very sensitive to delay and jitter.
第10题:
The forwarding table lists each source protocol and preference for each destination.
The forwarding table contains only active routes.
The forwarding table is used to process transit packets.
The forwarding table is stored in compact flash.
第11题:
RTP multiplexing is used to keep multiple phone conversations separate
RTP provides end-to-end delivery services for voice traffic.
UDP is used to ensure a reliable transmission from sender to receiver.
RTP is used to provide resource reservation for the voice stream.
UDP provides multiplexing of multiple phone conversations.
第12题:
It fragments and encapsulates all packets in a fragmentation header.
Packets smaller than the fragmentation size are interleaved between the fragments of the larger packets.
Packets larger than the fragmentation size are always fragmented, and cannot be interleaved, even if the traffic is voice traffic.
It fragments and encapsulates packets that are longer than a configured size, but does not encapsulate smaller packets inside a fragmentation header.
第13题:

SLA responder knows type of operation, the port used, and duration.
SLA responder inserts in and out timestamps in the packet payload.
SLA sender and responder use the IP SLA Control Protocol to communicate with each other before
SLA sender and responder communication can be encrypted.
SLA sender and responder communication can be authenticated with MD5.
第19题:
The Junos OS applies service ALGs only for the first packet of a flow.
The Junos OS uses fast-path processing only for the first packet of a flow.
The Junos OS performs policy lookup only for the first packet of a flow.
The Junos OS applies SCREEN options for both first and consecutive packets of a flow.
第20题:
latency must be kept below 150 ms
latency is not a concern as long as jitter is kept below 30 ms
voice packets do not require a specific type of queuing
voice packets are rather small
voice packets require TCP for rapid retransmission of dropped packets
voice packets require a fairly constant bandwidth reserved for voice control traffic as well as forthe voice payload
第21题:
The receiver acknowledges the final packet in each communications stream.
The receiver adds sequencing numbers to the packets received.
The sender adds sequencing numbers to the packets it sends.
The receiver acknowledges each packet it receives from the sending device.
