第5题:
Which two statements about the QoS functionality of the Cisco SDM are true?()
第6题:
Which two queuing methods are supported by outbound QoS?() (Choose two.)
第7题:
FIFO queuing, which provides a means to hold packets while they are waiting to exit an interface
Priority queuing, which ensures a fixed amount of bandwidth
Custom queuing (CQ), which provides a queuing tool that services all queues, even during times of congestion
Bandwidth queuing, which ensures a minimum amount of bandwidth
Weighted fair queuing (WFQ), which classifies packets based on flows
第8题:
class-based weighted fair queuing (CBWFQ)
low latency queuing (LLQ)
priority queuing (PQ) or custom queuing (CQ)
Real-Time Transport Protocol (RTP) header compression
TCP header compression
UDP header compression
第9题:
FIFO queuing is only appropriate for slower serial interfaces
weighted fair queuing is the default queuing mechanism used for all but slower than E1 rate interfaces
only one queuing mechanism type can be applied to an interface
weighted fair queuing does not require the configuration of access lists to classify traffic
flow-based weighted fair queuing provides for queues to be serviced in a round-robin fashion
第10题:
Weighted Fair Queuing (WFQ)
Priority Queuing (PQ)
Class-based WFQ (CBWFQ)
Low Latency Queuing (LLQ)
第11题:
first-in, first-out queuing (FIFO)
priority queuing (PQ)
custom queuing (CQ)
weighted fair queuing (WFQ)
class-based WFQ (CBWFQ)
low latency queuing (LLQ)
第12题:
weighted fair priority
weighted fair queuing
weighted strict priority
weighted strict queuing
第13题:
To have the best possible voice quality and to utilize effectively the available bandwidth, which queuing and compression mechanisms need to be used?()
第14题:
Which statement is true about the components of a queuing mechanism?()
第15题:
What are two QoS mechanisms that are used to prevent packet loss?()
第16题:
Which two QoS statements are true about the use of the SDMQoS wizard?()
第17题:
你是企业的网络管理员,你想在你的企业里实现QOS以确保HTTP的应用数据流保证最小带宽为1M,你用下面哪种队列实现?()
第18题:
synchronizes FIFO, PQ, CQ, and MDRR, with WFQ, CBWFQ, and LLQ
enables strict priority queuing for voice traffic, and weighted round robin queuing for data traffic
enables low latency queuing to ensure that voice traffic receives priority treatment
enforces a trust boundary on switch access ports and uplinks/downlinks
modifies queue sizes as well as queue weights where required
adjusts link speeds to adapt to QoS needs
第19题:
Each subinterface has its own hardware queue and can experience congestion just like its main interface
Hardware queuing is only used if the software queues are experiencing congestion.
Hardware queues and software queues are not used concurrently.
The hardware queuing system always uses the FIFO queuing mechanism.
第20题:
Weighted Random Early Detection (WRED)
Low Latency Queuing (LLQ)
Class-based Weighted Fair Queuing (CBWFQ)
Modified Deficit Round Robin (MDRR)
第21题:
Business-critical traffic includes VoIP and voice signaling packets.
SDM can be used to configure a basic QoS policy for incoming traffic on WAN interfaces and IPsec tunnels.
SDM can provide QoS for real-time traffic and business-critical traffic.
SDM creates a custom-queuing (CQ) or a priority-queuing (PQ) policy.
SDM creates a low latency queuing (LLQ) service policy with its associated classes.
When allocating bandwidth, values can be entered in either bandwidth percentage or kilobytes per second (kBps).
第22题:
header compression
payload compression
low latency queuing (LLQ)
weighted random early detection (WRED)
traffic policing
traffic shaping
第23题:
the first step when using the SDM QoS wizard is to select the inbound interface on which the QoS policy must be applied
the SDM QoS wizard can be used to optimize LAN, WAN, and VPN interfaces
he SDM QoS wizard supports network-based application recognition (NBAR) to provide deep and stateful packet inspection
he SDM QoS wizard will apply custom queuing and priority queuing policies to the identified interfaces
he SDM QoS wizard will apply low latency-queuing,custom-queuing and priority-queuing policies to the identified interfaces
to create and manage the QoS settings, the user must select the QoS wizard task under the Monitor option
