Which network characteristic would best describe how well the network would support business critical applications in case of an unexpected increase of traffic?

QoS

Which network characteristic indicates the dependability of the components that make up the network?

reliability

What is the availability percentage over a one year period of the network that is not available for 15 minutes each month?

99.9657 percent

Which two statements about interface labels are true? (Choose two.)

An interface label is part of the physical topology diagram. An interface label includes information about the interface type.

Which network characteristic indicates the general expense to purchase, install, and maintain network components?

Cost

Which physical topology is depicted in the diagram?

The correct answer is "extended star." The central router could be considered a center of the star. Other devices connect to it. In the diagram, two switches (positioned to the left and under the router), connect multiple devices and each acts as a center of two smaller stars. In other words, tentacles of the router's star are stars themselves, so the topology is an extended star.

Which interface is defined in the S0/0/0 format?

The correct answer is "serial interface." The type of the interface is commonly identified by a letter: "S" is chosen to indicate a serial interface; "Fa" indicates a FastEthernet interface; and "Gi" indicates a Gigabit Ethernet interface.

Which three statements about network characteristics are true? (Choose three.)

The correct answers are "Bitrate is a measure of the data rate in bits per second of a given link in the network," "Availability is a measure of the probability that the network will be available for use when it is required," and "Reliability indicates the dependability of the components that make up the network." The physical, not the logical, topology depicts the arrangement of cables, devices, and end systems. Scalability is not concerned with the current count of network elements, only with its capability to grow without disturbances. QoS tells you how well a network supports business operations, especially in the case of congestions, while the security tells how well the network is defended from potential threats.

An employee has the option of working from home, and their home is located in the same town as the main office. The only option available to connect to the main office is to use the internet. The employee sets up the network, consisting of one desktop computer and a printer. Which statements regarding the workers SOHO are correct? (Choose two.)

The correct answers are "The SOHO network is an individual network that can function on its own" and "SOHO needs a connection to the internet to access the enterprise resources located at the main office." Although located in the same town, the home office is not and integral part of the main office LAN network. It can be considered a part of the overall enterprise network. When a remote worker needs to access enterprise resources, they need to connect to the main office network, in this case, via the internet. For entertainment and nonwork related activities, the SOHO network functions without having to connect to the main office. No internet connection is required for the devices within the home office to communicate with each other.

Which two options represent the meaning of the label Gi2/1? (Choose two.)

The correct answers are "The interface is a Gigabit Ethernet interface" and "There is more than one slot for interface cards on the hardware." The "G" letter in the "Gi" label signifies gigabit (a billion bits), which is the maximum speed of the interface. "Fa" letters would indicate a FastEthernet interface. Based on the interface label alone, you cannot tell what kind of device the interface is installed on nor what kind of cabling would be adequate for the port. This information is learned from the device specification. Both routers and switches can be equipped with Gigabit Ethernet interfaces.

Which four of the following are network intermediary devices? (Choose four.)

The correct answers are "access point," "firewall," "switch," and "wireless LAN controller." Tablets, laptops, sensors, and file servers do not interconnect devices or networks, therefore they are not intermediary devices. Tablets, laptops, temperature sensors, and file servers are examples of network end-devices.

Match the type of process to the correct application

The correct answers are: VoIP is a real-time application; An stock-exchange transaction is an interactive application; and FTP is considered a batch application.

You are given a physical network diagram. Which two statements about the logical diagram for the same network are true? (Choose two.)

The logical diagram can be drawn by examining device configurations. The logical diagram can be drawn by analyzing data flows in the network.

What are three examples of remote access locations? (Choose three.)

a network in an airport lounge branch offices small office/home office (SOHO)

In which type of applications does the user need to wait for a response when performing actions such as inventory lookup or a database update?

interactive applications

What is the function of a WLAN controller?

to automatically handle the configuration of wireless access point

What is the function of a firewall

to monitor and control the incoming and outgoing network traffic
