IPv4 and Network Segmentation

Which three IP addresses are private ? (Choose three.) 10.1.1.1 172.32.5.2 192.167.10.10 172.16.4.4 192.168.5.5 224.6.6.6

10.1.1.1 172.16.4.4 192.168.5.5 The private IP addresses are within these three ranges: 10.0.0.0 - 10.255.255.255 172.16.0.0 - 172.31.255.255 192.168.0.0 - 192.168.255.255

Which two statements are correct about private IPv4 addresses?(Choose two). Any organization (home, school, office, company) can use the 10.0.0.0/8 address. 172.99.1.1 is a private IPv4 address. Internet routers will typically forward any packet with a destination address that is a private IPv4 address. Private IPv4 addresses are assigned to devices within an organization's intranet (internal network).

A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why? This is a loopback address. This is a link-local address. This is a private IP address. There is an IP address conflict.

This is a private IP address. The IP address 192.168.25.10 is an IPv4 private address. This address will not be routed over the internet, so school A will not be able to reach school B. Because the address is a private one, it can be used freely on an internal network. As long as no two devices on the internal network are assigned the same private IP, there is no IP conflict issue. Devices that are assigned a private IP will need to use NAT in order to communicate over the internet.

Which two statements are correct about public IPv4 addresses?(Choose two). To access a device over the internet, the destination IPv4 address must be a public address. 192.168.1.10 is a public IPv4 address. Public IPv4 addresses are allowed to be assigned to devices within an organization's intranet (internal network). Public IPv4 address exhaustion is a reason why there are private Ipv4 addresses and why organizations are transitioning to IPv6.

A host is transmitting a broadcast. Which host or hosts will receive it? all hosts in the same network a specially defined group of hosts the closest neighbor on the same network all hosts on the internet

all hosts in the same network A broadcast is delivered to every host that has an IP address within the same network.

A message is sent to all hosts on a remote network. Which type of message is it? limited broadcast multicast directed broadcast unicast

directed broadcast A directed broadcast is a message sent to all hosts on a specific network. It is useful for sending a broadcast to all hosts on a nonlocal network. A multicast message is a message sent to a selected group of hosts that are part of a subscribing multicast group. A limited broadcast is used for a communication that is limited to the hosts on the local network. A unicast message is a message sent from one host to another.

Which address prefix range is reserved for IPv4 multicast? 240.0.0.0 - 254.255.255.255 224.0.0.0 - 239.255.255.255 169.254.0.0 - 169.254.255.255 127.0.0.0 - 127.255.255.255

224.0.0.0 - 239.255.255.255 Multicast IPv4 addresses use the reserved class D address range of 224.0.0.0 to 239.255.255.255. Complete Question 10 Question 10

Which statement describes one purpose of the subnet mask setting for a host? It is used to describe the type of the subnet. It is used to identify the default gateway. It is used to determine to which network the host is connected. It is used to determine the maximum number of bits within one packet that can be placed on a particular network.

It is used to determine to which network the host is connected. An IPv4 address contains two portions. The network portion defines the network (or a subnet) where the host is located and the host portion identifies the host address on the network. The subnet mask is used to define the network portion of the IPv4 addressing through the logical ANDing of the IP address and the subnet mask.

A user is unable to access the company server from a computer. On issuing the ipconfig command, the user finds that the IP address of the computer is displayed as 169.254.0.2. What type of address is this? private link-local loopback experimental

link-local IPv4 addresses in the address block 169.254.0.0 to 169.254.255.255 are link-local addresses. The operating system of a host can automatically assign an address from this block to the host in case no IP configuration is available. An example is when a host is configured to obtain a dynamic IP address but cannot reach any DHCP server during the boot process. In such a case, the operating system can assign a link-local address.

What is the role of IANA? maintaining standards related to electrical wiring and connectors documenting developments for new protocols and updating existing protocols managing the allocation of IP addresses and domain names promoting the development and evolution of the Internet around the world

managing the allocation of IP addresses and domain names Four very important organizations that create and maintain open standards are: The Internet Assigned Numbers Authority (IANA) oversees and manages the allocation of IP addresses and domain names to preserve their uniqueness. The Electronic Industries Alliance (EIA) maintains standards related to wiring and connectors to ensure cabling interoperability between different devices. The Internet Engineering Task Force (IETF) maintains the technologies and protocols used on the internet, such as TCP/IP. The Internet Society (ISOC) promotes the use of the internet around the world.

Which devices will not forward an IPv4 broadcast packet by default? Ethernet switch router Windows PC None of the above. All devices forward IPv4 broadcast packets by default.

router

Which network device can serve as a boundary to divide a Layer 2 broadcast domain? router Ethernet bridge Ethernet hub access point

router Layer 1 and 2 devices (LAN switch and Ethernet hub) and access point devices do not filter MAC broadcast frames. Only a Layer 3 device, such as a router, can divide a Layer 2 broadcast domain.

Which two situations are the result of excessive broadcast traffic? (Choose two) slow network operations when devices on all adjacent networks are affected slow device operations when the router has to forward an excessive number of packets

slow network operations slow device operations

What is one reason for subnetting an IP network? to reduce the scope of broadcast flooding to increase the number of available host addresses on the network to remove the need for network services that rely on broadcasts, such as DHCP to ensure that all devices can communicate with each other without requiring a router

to reduce the scope of broadcast flooding In flat networks where all hosts are on the same network, broadcast packets can quickly degrade the quality of the network performance. With the creation of smaller subnets, the broadcast traffic is isolated from other areas on the network. Devices on one subnet need to send traffic to a router to reach a host on a different subnet, and routers do not typically forward broadcast traffic.
