1. Question 1Server Administration

   A server administrator needs to add a new user to a Linux server with a specific home directory and a default shell. Which command is appropriate?

   1. Aping -c 4 -W 2 -s 1400 gateway01
   2. Buseradd with -m and -s options
   3. Cpasswd -n 7 -x 90 jdoe
   4. Ddf -h --output=source,size
   Show answer and explanationHide answer

   Correct answer: B

   useradd with -m creates a home directory and -s sets the shell. passwd sets passwords, ping tests reachability, and df reports disk usage.

2. Question 2Server Hardware Installation and Management

   A technician is installing a server that must remain available if one power supply fails. Which feature should be specified?

   1. AA power strip with surge protection only
   2. BRedundant hot-swappable power supplies
   3. CA single larger power supply
   4. DA UPS with no server PSU redundancy
   Show answer and explanationHide answer

   Correct answer: B

   Redundant hot-swappable power supplies keep the server running if one fails and allow replacement without downtime. A single supply, a UPS alone and surge protection do not provide PSU redundancy.

3. Question 3Troubleshooting

   Which TWO are common causes of a server failing to boot? (Choose two.)

   1. AA good network cable connected to the NIC
   2. BA laptop battery that is fully charged
   3. CA missing or corrupted boot device
   4. DAn incorrect boot order in the firmware settings
   5. EThe correct date and time set in the firmware
   Show answer and explanationHide answer

   Correct answer: C, D

   A missing boot device and incorrect boot order prevent boot. A good network cable, correct time and unrelated laptop batteries do not stop a server from booting.

4. Question 4Security and Disaster Recovery

   Which TWO are valid ways to protect server data against loss? (Choose two.)

   1. AStoring all data on one disk with no copies
   2. BRegular, tested backups stored off-site
   3. CRAID combined with a separate backup copy
   4. DDisabling backups to save space
   5. EKeeping backups only on the same server
   Show answer and explanationHide answer

   Correct answer: B, C

   Off-site, tested backups and RAID combined with separate backups protect against different failures. RAID alone is not a backup, and single-disk, disabled and same-server copies do not protect data.

5. Question 5Server Administration

   A Windows server administrator must restrict a file share so that only the finance group has modify permissions. Which permission model should be used?

   1. AAnonymous access enabled on the share so that unauthenticated clients can read
   2. BShare permissions set to Everyone with full control on the finance folder
   3. CNTFS permissions assigned to the finance group with modify rights
   4. DNo permissions set on the folder so access is inherited from the parent folder
   Show answer and explanationHide answer

   Correct answer: C

   NTFS permissions assigned to the finance group control access precisely. Everyone with full control, no permissions and anonymous access expose data.
