Partly checked. None of the 18 questions here has been read against the cited source by a person. 18 questions have been checked against their cited clause by an automated pass — which is not the same thing, and is not a signature.
Only questions a person has signed for are used in mock exams here. That is the whole difference between the two kinds of checking above.
Questions in this lesson
- A subnet is defined as 192.168.10.0/26. How many addresses in it can actually be assigned to hosts? machine-checked
- A host is configured with the address 172.20.35.77/20. What is the network address of its subnet? machine-checked
- In IPv6, which address is the loopback address, equivalent in role to 127.0.0.1 in IPv4? machine-checked
- Which is the correct fully compressed form of the IPv6 address 2001:0db8:0000:0000:0000:ff00:0042:8329? machine-checked
- Which pairing of a service with its default port number is correct? machine-checked
- DNS normally uses UDP port 53. In which situation does a DNS client or server fall back to TCP on port 53? machine-checked
- Which file on a Linux system maps service names such as ssh, smtp and http to their port numbers and transport protocols? machine-checked
- An administrator runs `ss -tulpn`. What does the `p` in that flag cluster add to the output? machine-checked
- The legacy command `ifconfig eth0 192.168.1.10 netmask 255.255.255.0` assigns an address to an interface. Which iproute2 command does the same job? machine-checked
- A host has an address on 192.168.1.0/24 but no default route. The router is 192.168.1.1. Which command installs the default gateway for the running system? machine-checked
- On a system whose networking is managed by NetworkManager, which command lists the configured connection profiles? machine-checked
- Which of these is the iproute2 replacement for `arp -n`, showing the mapping of neighbouring IP addresses to their MAC addresses? machine-checked
- Which two of the following IPv4 addresses come from the RFC 1918 private ranges? (Choose two.) machine-checked
- Which two statements about UDP are correct? (Choose two.) machine-checked
- Type the iproute2 command, with no interface argument, that displays the IP addresses currently assigned to all network interfaces. machine-checked
- Type the iproute2 command that prints the kernel routing table, the modern replacement for `route -n`. machine-checked
- Write the subnet mask for the prefix /26 in dotted-quad notation. machine-checked
- A host is configured as 192.168.7.100/28. Write the broadcast address of its subnet in dotted-quad notation. machine-checked
