• Question 112:

  Which of the following describes the concept of allocating more resources than what is available on a hypervisor?

  A. Direct access
  B. Overprovisioning
  C. Link aggregation
  D. Component redundancy
  E. Scalability
  B. Overprovisioning

  ---

  Explanation

  Overprovisioningrefers to allocating more resources (e.g., CPU, memory) to virtual machines on a hypervisor than the physical host actually has available. This is done because not all virtual machines are likely to use their maximum

  resources simultaneously. Overprovisioning helps optimize resource utilization on a hypervisor but must be managed carefully to avoid performance degradation. Overprovisioning (Answer B):It allows for more efficient use of resources, but

  overcommitting too much can lead to performance issues.

  Direct access (Option A):Refers to direct hardware access, which is unrelated to resource allocation.

  Link aggregation (Option C):Refers to combining multiple network connections, unrelated to hypervisor resources.

  Component redundancy (Option D):Refers to using backup components for fault tolerance, not related to overprovisioning.

  Scalability (Option E):Refers to the ability to increase or decrease resources as needed but doesn't describe overcommitting resources.

  This topic is covered underSK0-005 Objective 1.3: Explain virtualization concepts and benefits.

• Question 113:

  A server technician is installing a Windows server OS on a physical server. The specifications for the installation call for a 4TB data volume. To ensure the partition is available to the OS, the technician must verify the:

  A. hardware is UEFI compliant
  B. volume is formatted as GPT
  C. volume is formatted as MBR
  D. volume is spanned across multiple physical disk drives
  B. volume is formatted as GPT

  ---

  Explanation

  To ensure the partition is available to the OS, the technician must verify that the volume is formatted as GPT. GPT (GUID Partition Table) is a partitioning scheme that defines how data is organized on a hard disk drive (HDD) or a solid state drive (SSD). GPT uses globally unique identifiers (GUIDs) to identify partitions and supports up to 128 primary partitions per disk. GPT also supports disks larger than 2 TB and has a backup copy of the partition table at the end of the disk for data recovery. GPT is required for installing Windows on UEFI-based PCs, which offer faster boot time and better security than legacy BIOS-based PCs.

• Question 114:

  Which of the following BEST describes a guarantee of the amount of time it will take to restore a downed service?

  A. RTO
  B. SLA
  C. MTBF
  D. MTTR
  A. RTO

  ---

  Explanation

  The guarantee of the amount of time it will take to restore a downed service is typically referred to as the "RTO" or "Recovery Time Objective." RTO is the amount of time within which a system, application, or service must be restored after a

  disruption in order to avoid unacceptable consequences associated with a break in business continuity.

  Option A, RTO, is the correct answer.

  Option B, SLA (Service Level Agreement), is an agreement between a service provider and its customers that defines the level of service, availability, and other aspects of the service that the provider agrees to deliver.

  Option C, MTBF (Mean Time Between Failures), is the average time that elapses between failures of a system, component, or product.

  Option D, MTTR (Mean Time To Repair), is the average time it takes to repair a system, component, or product after a failure has occurred.

• Question 115:

  A server administrator is replacing a faulty PSU. The management team has asked for a solution that prevents further downtime in the future.

  Which of the following can the server administrator implement?

  A. Separate circuits
  B. Load balancing
  C. Server monitoring
  D. Redundancy
  D. Redundancy

  ---

  Explanation

  A faulty PSU needs replacement, and the management team wants a solution to prevent future downtime.

  Solution: Implement redundancy (Option D):

• Question 116:

  An administrator is investigating a physical server mat will not Boot into the OS. The server has three hard drives configured in a RAID 5 array. The server passes POST, out the OS does not load. The administrator verities the CPU and RAM

  are Doth seated correctly and checks the dual power supplies. The administrator then verifies all the BIOS settings are correct and connects a bootable USB drive in the server, and the OS loads correctly.

  Which of the following is causing the issue?

  A. The page file is too small.
  B. The CPU has failed.
  C. There are multiple failed hard drives.
  D. There are mismatched RAM modules.
  E. RAID 5 requires four drives
  C. There are multiple failed hard drives.

  ---

  Explanation

  If a server has three hard drives configured in a RAID 5 array, it means that the data is striped across all three drives with parity information. RAID 5 can tolerate one drive failure without losing data, but not two or more. If there are multiple

  failed hard drives, the RAID 5 array will become corrupted and the OS will not load. The other options are not likely to cause the issue, as the server passes POST, the CPU and RAM are seated correctly, the BIOS settings are correct, and

  the OS loads from a bootable USB drive. RAID 5 does not require four drives, it can work with three or more.

• Question 117:

  A company uses a hot-site, disaster-recovery model. Which of the following types of data replication is required?

  A. Asynchronous
  B. Incremental
  C. Application consistent
  D. Constant
  D. Constant

  ---

  Explanation

  The type of data replication that is required for a hot-site disaster recovery model is constant. A hot site is a type of disaster recovery site that has fully operational IT infrastructure and equipment that can take over the primary site's functions immediately in case of a disaster or disruption. A hot site requires constant data replication between the primary site and the hot site to ensure that the data is up-to-date and consistent. Constant data replication means that any changes made to the data at the primary site are immediately copied to the hot site without any delay or lag.

• Question 118:

  A systems administrator is trying to run a program on the server to query the database. When attempting to launch the program, the screen flashes and the program closes. Which of the following should the technician do to get the program to open correctly? (Choose two.)

  A. Launch the program running as the administrator.
  B. Check HIPS logs to see if the application is blocked.
  C. Log on to the server as the backup administrator.
  D. Log on to the server as the database administrator.
  E. Stop the database and restart the server.
  A. Launch the program running as the administrator.
  B. Check HIPS logs to see if the application is blocked.

• Question 120:

  A server administrator noticesthe/var/log/audit/audit.logfileon a Linux server is rotating loo frequently. The administrator would like to decrease the number of times the leg rotates without losing any of the information in the logs. Which of the following should the administrator configure?

  A. increase theaudit. log file size in the appropriate confutation file.
  B. Decrease the duration of the log rotate cycle tor theaudit. log file.
  C. Remove the tog rotate directive from the audit .log We configuration.
  D. Move the audit. leg files to a remote syslog server.
  A. increase theaudit. log file size in the appropriate confutation file.

  ---

  Explanation

  The audit.log file is a file that records security-related events on a Linux server, such as user login, file access, and system commands. The logrotate utility is a tool that rotates, compresses, and deletes old log files based on certain criteria, such as size, time, or frequency. To decrease the number of times the log rotates without losing any information, the administrator should increase the audit.log file size in the appropriate configuration file, such as /etc/logrotate.conf or /etc/ logrotate.d/auditd.
