* Access to files and directories must be granted based only on SELinux contexts.
* The SELinux configuration must be persistent across system restarts.
* Users must be able to publish private HTML content.
Now examine these commands and output:
# sestatus
SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: permissive
Mode from config file: permissive
Policy MLS status: enabled
Policy deny_unknown status: allowed
Memory protection checking: actual (secure)
Max Kernel policy version: 31
# setenforce enforcing
# semanage login -a -s guest_u oracle
# setsebool -P http_enable_homedirs on
Which requirements are satisfied?

  • A. 1, 2, 6
  • B. 1, 2, 3, 4, 5, 6
  • C. 1, 2, 4, 5, 6
  • D. 1, 2, 3, 6
  • E. 1, 2, 4, 6
  • F. 1, 2, 3, 5, 6

Answer: C

Explanation:
Explanation of Answer A:
* Network services running in a confined domain: SELinux provides domain confinement for services, ensuring they run with restricted access based on their defined policies.
* The oracle user must be confined: The commandsemanage login -a -s guest_u oracleconfines theoracleuser to theguest_uSELinux user role, which is a confined role.
* Access to files and directories based only on SELinux contexts: With SELinux enabled and the policy loaded, access is governed by SELinux contexts.
* Persistent SELinux configuration across reboots: Thesetenforce enforcingcommand, combined with the appropriate policy configuration, ensures that SELinux remains in enforcing mode across reboots.
* Users able to publish private HTML content: Thesetsebool -P http_enable_homedirs oncommand enables the use of user home directories for web content, allowing users to host personal web pages.


NEW QUESTION # 18
Examine this command:
# nft add rule inet filter input tcp dport 80 drop
Which two statements are true upon execution?

  • A. The rule applies to the input table.
  • B. TCP packets outbound on port 80 are dropped.
  • C. TCP packets inbound on port 80 are dropped.
  • D. The rule is applied to both IPv4 and IPv6 packets.
  • E. The rule updates the configuration on disk.
  • F. All traffic inbound on port 80 is dropped.

Answer: C,D

Explanation:
* Option A (Correct):The rule is applied to both IPv4 and IPv6 packets. Theinettable is used for filtering both IPv4 and IPv6 traffic, and since the rule is added to theinettable, it affects both IP versions.
* Option E (Correct):The rule drops TCP packets inbound on port 80. The rule specifies theinputchain in thefiltertable, and it drops (drop) all TCP traffic (tcp) destined for port 80 (dport 80), which means any incoming TCP traffic on port 80 will be dropped.
* Option B (Incorrect):The command does not automatically update the configuration on disk; the rule is applied immediately in memory but does not persist across reboots unless explicitly saved.
* Option C (Incorrect):The rule specifies TCP packets only, not all traffic. Therefore, it does not drop traffic for protocols other than TCP.
* Option D (Incorrect):Although this statement is correct, it is less specific than Option A, which is more accurate because it mentions both IP versions.
* Option F (Incorrect):The rule applies to inbound traffic, not outbound, so it does not drop outbound traffic.

NEW QUESTION # 20
Which three are features of the btrfs file system?

  • A. Block devices mirroring
  • B. Cluster file system
  • C. Efficient storage for small files
  • D. Copy-on-write metadata
  • E. Automatic defragmentation
  • F. General-purpose volume manager
  • G. Online resizing

Answer: D,E,G

Explanation:
* Option B (Correct):Btrfs uses a copy-on-write mechanism for both data and metadata, which ensures that the file system is more resilient to crashes and data corruption.
* Option E (Correct):Btrfs supports online resizing, meaning that you can change the size of a mounted Btrfs file system without unmounting it.
* Option G (Correct):Btrfs automatically defragments files in the background to maintain performance.
* Option A (Incorrect):While Btrfs does support mirroring, it is not strictly block device mirroring in the traditional sense like RAID; it uses a different approach to redundancy.
* Option C (Incorrect):Btrfs is not a cluster file system; it is designed for local file systems.
* Option D (Incorrect):While Btrfs can store small files efficiently, it is not its primary design goal compared to other file systems optimized specifically for small files.
* Option F (Incorrect):Btrfs is a file system with integrated volume management capabilities but is not a general-purpose volume manager like LVM.
