Which of the following nmcli subcommands exist? (Choose TWO correct answers). nmcli address. nmcli ethernet. nmcli wifi. nmcli connection. nmcli device.

Which of the following changes may occur as a consequence of using the command ip? (Choose THREE correct answers). The routing table may change. Network interfaces may become active or inactive. New name servers may be added to the resolver configuration. The system’s host name may change. IP addresses may change.

How many IP addresses can be used for unique hosts inside the IPv4 subnet 192.168.2.128/26?. 62. 30. 6. 126. 14.

Which of the following IPv4 networks are reserved by IANA for private address assignment and private routing? (Choose THREE correct answers). 172.16.0.0/12. 127.0.0.0/8. 192.168.0.0/16. 169.255.0.0/16. 10.0.0.0/8.

Which of the following commands configure network interfaces based on the system’s existing distribution specific configuration files? (Choose TWO correct answers). ifup. ifstart. ifdown. ifpause. ifconf.

Which of the following statements is true if the UID of a regular user is identical to the GID of a group?. The user is the only member of the group, even if the group configuration contains other members. The user as well as the group are not available to avoid ambiguity due to the ID conflict. GIDs have precedence over UIDs, therefore the group is available while the user isn’t. UID have precedence over GIDs, therefore the user is available while the group doesn’t. UIDs and GIDs are independent of each other, therefore the user as well as the group are still available.

Which of the following information is stored in /etc/shadow for each user?. The user’s private SSH keys. The path to the user’s home directory. The hashed password of the user. The timestamp of the user’s last login. The numerical user ID (UID).

Which of the following commands shows all active systemd timers?. systemctl –t. systemctl-timer show. timeq. systemctl list-timers. timectl list.

Which of the following tasks can the date command accomplish? (Choose TWO correct answers). Set the system’s date but not the time. Print a calendar for a month or a year. Display time in a specific format. Set the system’s date and time. Calculate the time span between two dates.

Which of the following is a valid IPv6 address?. 2001:db8:3241::1. 2001::db8:4581::1. 2001.db8.819f..1. 2001:db8:0g21::1. 2001%db8%9990%%1.

What can be specified with useradd? (Choose TWO correct answers). The numeric user ID (UID) of the user. The SSH keys used to login to the new account. Commands the user can run using sudo. The absolute path to the user’s home directory. Which printers are available for the new user.

Which if the following tools, used for DNS debugging, reports not only the response from the name sever but also details about the query?. dig. dnsq. dnslookup. hostname. zoneinfo.

Which of the following statements is valid in the file /etc/nsswitch.conf?. hosts: files dns. 192.168.168.4 dns-server. namespaces: net mount procs. include /etc/nsswitch.d/. multi on.

Which of the following connection types, as seen in nmcli connection show, may exist in NetworkManager? (Choose THREE correct answers). tcp. wifi. ethernet. ipv6. bridge.

On a Linux workstation, the route command takes a long time before printing out the routing table. Which of the following errors does that indicate?. One of the routers in the routing table is not available which causes the automatic router failure detection mechanism (ARF-D) to wait for a timeout. The Linux Kernel Routing Daemon (LKRD) is not running and should be started using its init script or systemd unit. There may accidentally be more than one default router in which case a default router election has to be done on the network in order to choose one router as the default. DNS resolution may not be working as route by default tries to resolve names of routers and destinations and may run into a timeout. The local routing information may be corrupted and must be revalidated using a routing protocol.

What is true about the Hop Limit field in the IPv6 header?. For multicast packages, the field’s value is always 1. Each router forwarding the packet decreases the field’s value. Each router forwarding the packet increases the field’s value. The field is transmitted within a hop-by-hop extension header. The field is not changed during the transport of a package.

Which command is used to set the hostname of the local system? (Specify only the command without any path or parameters).

Which file, if present, must contain all users that are allowed to use the cron scheduling system? (Specify the full name of the file, including path).

What command, depending on its options, can display the open TCP connections, the routing tables, as well as network interface statistics? (Specify only the command without any path or parameters).

Which command included in NetworkManager is a curses application which provides easy acces to the NetworkManager on the command line? (Specify only the command without any path or parameters).
