Section 1.7 Demonstrate your acquired knowledge about IPv4 Network Addressing. This will demonstrate your proficiency for section 1.7 of the Network+ 10-009 objectives. 1 / 25 Which of the following best defines Class E IPv4 addresses? Reserved for multicast traffic Reserved for future or experimental use Reserved for private networks Used for broadcast communication 2 / 25 Given the IP address 172.31.0.0 with a subnet mask of 255.255.240.0, how many possible subnets are available? 8 16 32 64 3 / 25 Which of the following IP address classes can accommodate the most number of hosts? Class A Class B Class C Class D 4 / 25 Which of the following best defines the purpose of APIPA (Automatic Private IP Addressing)? It allows a device to automatically assign itself an IP address in the private IP range if DHCP is unavailable. It assigns a public IP address to devices without a DHCP server. It enables devices to route traffic to other subnets. It configures devices for loopback communication. 5 / 25 If a network is using a subnet mask of 255.255.255.240, how many available IP addresses are there in each subnet? 8 16 14 30 6 / 25 Which of the following is a valid IP address in the Class B address range? 10.10.10.10 128.20.30.40 192.168.1.1 224.0.0.1 7 / 25 What does the subnet mask 255.255.255.248 represent in terms of the number of hosts? 6 hosts 14 hosts 30 hosts 62 hosts 8 / 25 Given the CIDR notation 192.168.1.0/24, which subnet mask is used? 255.255.255.0 255.255.255.128 255.255.255.192 255.255.255.255 9 / 25 If an IPv4 address is assigned 255.255.255.224 as the subnet mask, how many subnets can be created? 8 16 32 64 10 / 25 What is the purpose of CIDR (Classless Inter-Domain Routing) notation? It allows for more efficient use of IP address space by enabling variable-length subnet masks. It defines the IP address ranges for private use. It reserves IP address ranges for multicast communications. It specifies a fixed length for subnet masks across all networks. 11 / 25 Which of the following is a valid IPv4 address class for public addresses? Class A Class B Class C All of the above 12 / 25 Which IP address class is typically used for large-scale enterprise networks with many hosts? Class A Class B Class C Class D 13 / 25 What is the range of IP addresses for a Class C network? 192.0.0.0 to 223.255.255.255 128.0.0.0 to 191.255.255.255 0.0.0.0 to 127.255.255.255 224.0.0.0 to 255.255.255.255 14 / 25 If you are given the IP address 192.168.1.10 with a subnet mask of 255.255.255.240, what is the maximum number of hosts that can be configured on this subnet? 6 14 30 254 15 / 25 What is the significance of a subnet mask in an IPv4 network? It defines the range of IP addresses a device can communicate with. It identifies the network portion and host portion of an IP address. It determines whether the device is public or private. It routes traffic between different subnets. 16 / 25 Which of the following IP addresses falls within the APIPA (Automatic Private IP Addressing) range? 192.168.1.100 169.254.25.50 10.0.0.50 172.16.100.1 17 / 25 Which of the following represents the correct subnet mask for a Class A address when using the default subnet mask? 255.255.255.0 255.255.0.0 255.0.0.0 255.255.255.255 18 / 25 Which of the following IP addresses is a valid private IP address according to RFC 1918? 172.15.0.0 192.168.100.1 10.256.0.0 200.200.200.200 19 / 25 What is the range of IP addresses in the Class B network address space? 0.0.0.0 to 127.255.255.255 128.0.0.0 to 191.255.255.255 192.0.0.0 to 223.255.255.255 224.0.0.0 to 255.255.255.255 20 / 25 In a subnet with the network address 192.168.10.0 and a subnet mask of 255.255.255.192, how many subnets can be created? 2 4 8 16 21 / 25 Which IPv4 address class is used for multicast communications? Class A Class B Class C Class D 22 / 25 Which of the following is the correct subnet mask for an IP address in a Class C network? 255.0.0.0 255.255.0.0 255.255.255.0 255.255.255.255 23 / 25 What is the purpose of the loopback address 127.0.0.1 in IPv4? It allows for communication within the local subnet. It routes traffic between different networks. It is used for testing and troubleshooting the local machine's network stack. It is assigned to routers for routing purposes. 24 / 25 Which of the following best describes an IP address in the range 169.254.0.1 to 169.254.255.254? Private IP address Public IP address APIPA (Automatic Private IP Addressing) address Reserved address for loopback 25 / 25 Which of the following IP address ranges is reserved for private use according to RFC 1918? 192.168.0.0 - 192.168.255.255 172.16.0.0 - 172.31.255.255 10.0.0.0 - 10.255.255.255 All of the above Your score is 0% Restart quiz
