01. What is the relationship between a container image and a running container?
a) The image is a snapshot captured from a running container, and it can be produced in no other way
b) The image is a read-only template
c) The container is a full copy of the image, written out in full when it starts
d) The image and the container are one object in different states of the same file
02. A log file is rotated nightly. The application writing it holds its file descriptor open and never reopens the file, so after each rotation it keeps writing into the rotated copy while the new file stays empty. The application cannot be modified.
Which rotation behavior resolves it?
a) Copy the file's contents aside and truncate the original in place
b) Create the replacement file with the same ownership and permissions before the application writes to it again
c) Delay the rotation until the application has been idle for a defined period
d) Compress the rotated file so that the application notices the change
03. Local accounts must be able to transfer files with FTP, and none of them may reach anything outside their own home directory.
Which configuration achieves this?
a) Allow anonymous logins only, with a shared upload directory
b) Allow local logins, and set the server's root directory to /home
c) Allow local logins, and confine each user to their own home directory
d) Allow local logins, and remove execute permission from the directories above the homes
04. An administrator inspects a bond's status file and finds:
Bonding Mode: fault-tolerance (active-backup) Currently Active Slave: enp0s8 MII Status: up
What does this confirm?
a) Both ports are carrying traffic and sharing the load between them
b) The bond has failed over and is now running without redundancy
c) The named port has failed, and its partner has taken the traffic
d) The bond is up, and traffic is currently carried by the port named as active
05. Time on a server has drifted. Querying the time daemon shows the same leading field for every configured source:
^? 192.0.2.10 0 6 0 - +0ns[ +0ns] +/- 0ns
What does this indicate?
a) The sources are reachable, and their offset is too large to correct gradually
b) No source has been reached
c) The clock is already synchronized and no correction is being applied
d) The daemon is configured to serve time to clients without consuming it
06. Data written by an application inside a container has to outlive that container, so that the container can be replaced with a newer image without loss.
Which two arrangements achieve this?
(Choose two.)
a) A named volume managed by the engine, mounted into the container
b) A directory on the host bind-mounted into the container
c) A copy in the container's writable layer, which the engine retains
d) A new image layer committed after each run
07. After a reboot, journal entries from before the restart are gone, although the journal is otherwise working normally.
What explains this?
a) The entries were forwarded to the syslog daemon and dropped from the journal
b) The journal was rotated during the boot and the previous file was removed
c) The journal retains only the current boot by design, and this cannot be altered
d) The journal is being kept in volatile storage
08. Key-based access has been rolled out and verified for every administrator. The team wants to remove the possibility of a guessed password over the network, while leaving console login unchanged.
What should be done?
a) Lock every account's password so that there is no password to guess
b) Turn off password authentication in the server's configuration and reload it
c) Require a long minimum password length for every account
d) Move the service to a non-standard port so that attempts are not aimed at it
09. Which utility installs a user's public key into the authorized keys file of an account on a remote host?
a) ssh-copy-id
b) ssh-agent
c) ssh-keygen
d) ssh-keyscan
10. One named user has to be given write access to a file. The owner, the owning group and everyone else's access must stay exactly as they are.
What achieves this?
a) Add the user to the file's owning group
b) Change the file's group to one containing only that user
c) Add an access control list entry for that user on the file
d) Make the file writable by every account on the system
