A)SLA
B)QoS
C)LAN
D)DS

Accepted Answer

SLA (Service Level Agreement) typically includes the nature of service to be provided, expected performance level of the service, and the process for monitoring and reporting the service level. QoS (Quality of Service) is a technique used to prioritize network traffic, LAN (Local Area Network) is a type of network used in a small geographical area, and DS (Data Set) is a dataset used in statistical analysis.

Question 2

A practical application for multicasting is:
A)teleconferencing
B)multimedia
C)database
D)all of the above

Accepted Answer

Multicasting is used in various applications where the same data needs to be transmitted to multiple recipients. This includes teleconferencing, where participants in different locations join a virtual meeting; multimedia services, such as streaming live video or audio to multiple users; and certain database operations that involve distributing updates or information to multiple clients simultaneously.

Question 3

__________ is an identifier for a single interface in which a packet is delivered to the interface identified by that address.

Accepted Answer

The answer of __________ is an identifier for a single...

Question 4

Multiple IP addresses referring to a block of CIDR addresses can be identified with a single mask,a process known as __________ .
A)uni-masking
B)OSPF
C)supernetting
D)block masking

Accepted Answer

Supernetting (also known as CIDR aggregation or route summarization) is the process of combining multiple smaller blocks of IP addresses into a larger block, which can then be represented with a single CIDR prefix or subnet mask. This reduces the number of entries in routing tables and simplifies routing across networks.

Question 5

Three functional procedures are involved in the Border Gateway Protocol (BGP): neighbor acquisition,neighbor reachability,and __________.

Accepted Answer

The answer of Three functional procedures are involved in the...

Question 6

Question 7

IPv6 allows three types of addresses: unicast,anycast,and _________.

Accepted Answer

The answer of IPv6 allows three types of addresses: unicast,anycast,and...

Question 8

IPv6 includes ________ address fields.
A)16-bit
B)32-bit
C)64-bit
D)128-bit

Accepted Answer

IPv6 includes 128-bit address fields, which allows for a much larger number of unique addresses compared to IPv4's 32-bit address fields. This increased address space is necessary to accommodate the growing number of devices and users accessing the internet.

Question 9

Today,_________ is the most widely accepted QoS mechanism in enterprise networks.
A)AS
B)SLA
C)DS
D)SSL

Accepted Answer

DS (Differentiated Services) is the most widely accepted QoS mechanism in enterprise networks as it allows for the classification of traffic and prioritization based on the requirements of the application. AS (Autonomous System) is a routing protocol used by ISPs, SLA (Service Level Agreement) is a contract between a service provider and a user, and SSL (Secure Sockets Layer) is a security protocol for web browsing. None of these are QoS mechanisms.

Question 10

The answer of _________ is an identifier for a set...

Question 11

_________ makes more efficient use of the 32-bit IP address than the class-based method primarily because it makes more efficient use of the address space.

Question 12

To identify a host on the Internet,each host is assigned a unique IP address,which consists of two logical components: a network component and a ________ component.

Accepted Answer

The answer of To identify a host on the Internet,each...

Question 13

The magnitude of delay variation,called ________ ,is a critical factor in realtime applications.
A)jitter
B)stuttering
C)supernetting
D)latency

Accepted Answer

Jitter refers to the variation in delay of consecutive packets or data transmissions. In real-time applications, such as video conferencing or online gaming, excessive jitter can lead to poor quality and disruption of the communication. Therefore, minimizing jitter is important to maintain consistent and reliable communication.

Question 14

_________ is an identifier for a set of interfaces in which a packet is delivered to one of the interfaces identified by that address (the "nearest" one,according to the routing protocols' measure of distance).

Accepted Answer

The answer of _________ is an identifier for a set...

Question 15

The _________ in an internet are responsible for receiving and forwarding packets through the interconnected set of networks,making routing decisions based on knowledge of the topology and traffic / delay conditions of the internet.
A)gateways
B)routers
C)channels
D)links

Accepted Answer

Routers are devices in the internet that are responsible for receiving and forwarding packets to their destinations based on the topology and traffic conditions of the internet. Gateways are similar but are mainly used to interface different types of networks rather than forward packets within a network. Channels and links refer to the physical connections between devices and do not have decision-making capabilities like routers.

Question 16

An autonomous system (AS)exhibits which of the following characteristics?
A)is a set of routers and networks managed by a single organization
B)consists of a group of routers exchanging information via a common routing protocol
C)except in times of failure is connected
D)all of the above

Accepted Answer

An autonomous system (AS) is a network operated by a single organization, such as a university, a company, or an Internet Service Provider (ISP). It consists of a group of routers exchanging information via a common routing protocol, such as Border Gateway Protocol (BGP), in order to provide connectivity to external networks. It is also expected to be connected under normal conditions, except for times of failure. Therefore, all of the above characteristics apply to an autonomous system.

Question 17

Which of the following detailed performance parameters might be included in an SLA?
A)service performance parameters,such as expected throughput,drop probability,and latency
B)constraints on the ingress and egress points at which the service is provided,indicating the scope of the service
C)traffic profiles that must be adhered to for the requested service to be provided
D)all of the above

Accepted Answer

All of the given options are possible detailed performance parameters that can be included in an SLA. Service performance parameters like throughput, drop probability, and latency are essential performance indicators. Constraints on ingress and egress points are necessary to define the scope of the service, and traffic profiles can significantly impact the service level. Therefore, all options are valid for inclusion in an SLA.

Question 18

The IP address is obtained either by looking it up in a configuration file or dynamically,via the ______________.

Accepted Answer

The answer of The IP address is obtained either by...

Question 19

The value of the DS field,referred to as the DS ________,is the label used to classify packets for differentiated services.
A)QoS
B)codepoint
C)SLA
D)supernetting

Accepted Answer

The DS codepoint is the label used to classify packets for differentiated services. The value of the DS field is used by network devices to provide quality of service (QoS) for different applications and services. SLA (Service Level Agreement) is an agreement between a service provider and customer that defines the level of service expected. Supernetting is a method of combining smaller network blocks into a larger block. None of these options accurately describe the DS field.
