For an IP service network, its QoS control mechanism usually includes two kinds of mod

From where does a small network typically get its IP network addresses or IP block？

A．From the Internet Domain Name Registry (IDNR)

B．From the Internet Assigned Numbers Authority (IANA)

C．From the Internet Service Provider (ISP)

D．From the Internet Architecture Board (IAB)

E．None of the above

ddress 189.66.1.0 by its Internet Service Provider. If you divide the network range by using the 255.255.255.224 subnet mask, how many hosts can be supported on each network？（）

A.14

B.16

C.30

D.32

E.62

F.64

The diffserv approach to providing QoS in networks employs a small, well-defined set of building blocks from which you can build a variety of(). Its aim is to define the differentiated services (DS) byte, the Type of Service (ToS) byte from the Internet Protocol Version 4 ()and the Traffic Class byte from IP Version 6, and mark the standardized DS byte of the packet such that it receives a particular forwarding treatment, or per-hop behavior (PHB), at each network node. The diffserv architecture provides a()within which service providers can offer customers a range of network services, each differentiated based on performance. A customer can choose the ()level needed on a packet-by-packet basis by simply marking the packet&39;s Differentiated Services Code Point (DSCP) field to a specific value.This () specifies the PHB given to the packet within the service provider network.

A.minimum cell rate (MCR)

C.modulation

rovided best-effort means of data （）using the Transmission Control Protocol/Internet Protocol Suite. Although the （）design gives the Internet its flexibility and robustness, its packet dynamics also make it prone to congestion problems,especially at （）that connect networks of widely different bandwidths.The initial QoS function set was for internet hosts.One major problem with expensive wide-area（）links is the excessive overhead due to small Transmission Control Protocol packets created by applications such as telnet and rlogin. The Nagle （），which solves this issue,is now supported by all IP host implementations.

A. Configure a single Junos Pulse Access Control Service instance on the enforcer, specifying the VIP as the IP address the instance.

B. Configure multiple Junos Pulse Access Control Service instances on the enforcer, specifying the specific IP address each device in a separate instance.

C. Configure a single Junos Pulse Access Control Service instance on the enforcer, specifying the VIP and active node address in the instance.

D. Configure a single Junos Pulse Access Control Service instance on the enforcer, specifying the VIP and passive node address in the instance.
