Q1Domain Verified
In the context of Docker volumes, which of the following statements best describes the primary mechanism for persistent data storage that is managed by Docker itself, independent of the container's lifecycle and host filesystem structure?
Docker volumes, managed by the Docker daemon and stored in a dedicated area on the host.
Network file systems (NFS), external storage solutions mounted into containers.
Bind mounts, allowing direct mapping of host directories into containers.
tmpfs mounts, utilizing volatile memory for temporary data storage.
Q2Domain Verified
A critical security concern arises when using bind mounts for sensitive configuration files (e.g., SSH keys, private certificates) that are mounted into multiple containers. Which of the following is the most significant risk associated with this practice?
Performance degradation due to increased I/O operations between the host and containers.
Potential for privilege escalation if a compromised container can modify the host's configuration files.
Increased disk space consumption on the host as Docker duplicates the configuration files for each container.
Data corruption if multiple containers attempt to write to the same file simultaneously without proper locking.
Q3Domain Verified
Consider a scenario where you need to share a large dataset that is read-only by most containers but occasionally updated by a single administrative container. Which storage strategy offers the most efficient and manageable solution, minimizing data duplication and ensuring integrity?
Using multiple bind mounts, each pointing to a specific subset of the dataset.
Distributing the dataset across multiple tmpfs mounts to leverage in-memory spee
D) Copying the entire dataset into each container's writable layer.
Creating a named Docker volume and mounting it read-only to most containers, and read-write to the administrative container.
