• Question 451:

  Which of the following would MOST likely be part of the user authentication process when implementing SAML across multiple applications?

  A. SSO
  B. LDAP
  C. TACACS
  D. MFA
  A. SSO

  ---

  Explanation

  The term that is most likely part of the user authentication process when implementing SAML across multiple applications is SSO. SSO (Single Sign-On) is a way for users to be authenticated for multiple applications and services at once. With SSO, a user signs in at a single login screen and can then use a number of apps without having to enter their credentials again. SSO improves user experience and security by reducing password fatigue and phishing risks. SAML (Security Assertion Markup Language) is a protocol that enables SSO by providing a standardized way to exchange authentication and authorization data between an identity provider (IdP) and a service provider (SP). SAML uses XML-based messages called assertions to communicate user identity and attributes between parties.

• Question 452:

  A technician needs to provide a VM with high availability. Which of the following actions should the technician take to complete this task as efficiently as possible?

  A. Take a snapshot of the original VM
  B. Clone the original VM
  C. Convert the original VM to use dynamic disks
  D. Perform a P2V of the original VM
  B. Clone the original VM

  ---

  Explanation

  Cloning the original VM is the most efficient way to provide a VM with high availability. Cloning is the process of creating an exact copy of a VM, including its configuration, operating system, applications, and data. A cloned VM can be used as a backup or a replica of the original VM, and can be powered on and run independently. Cloning can be done quickly and easily using vSphere tools or other third-party software. By cloning the original VM and placing it on a different host server or availability zone, the technician can ensure that if the original VM fails, the cloned VM can take over its role and provide uninterrupted service to the users and applications.

• Question 453:

• Question 454:

  A backup application is copying only changed files each line it runs. During a restore, however, only a single file is used. Which of the following backup methods does this describe?

  A. Open file
  B. Synthetic full
  C. Full Incremental
  D. Full differential
  B. Synthetic full

  ---

  Explanation

  A synthetic full backup is a backup method that describes copying only changed files each time it runs and using only a single file during a restore. A synthetic full backup is a backup approach that involves creating a new full backup by using

  the previous full backup and related incremental backups. This means that a backup solution does not have to transfer the full amount of data from the source machine and can synthetize the latest incremental backups with the last full

  backup to create a new full backup. This reduces the backup window and network bandwidth consumption. During a restore, only the latest synthetic full backup file is needed to recover the data. Open file backup is a backup method that

  allows backing up files that are in use or locked by applications. Full incremental backup is a backup method that involves performing a full backup first and then backing up only the changed files since the last backup. Full differential backup

  is a backup method that involves performing a full backup first and then backing up only the changed files since the last full backup.

• Question 455:

  Which of the following is a system that scans outgoing email for account numbers, sensitive phrases, and other forms of PII?

  A. SIEM
  B. DLP
  C. HIDS
  D. IPS
  B. DLP

  ---

  Explanation

  DLP stands for Data Loss Prevention and it is a system that scans outgoing email for account numbers, sensitive phrases, and other forms of PII (Personally Identifiable Information). DLP can help prevent data breaches, comply with

  regulations, and protect the privacy of customers and employees. DLP can also block, encrypt, or quarantine emails that contain sensitive data.

• Question 456:

  A server administrator is setting up a new payroll application. Compliance regulations require that all financial systems logs be stored in a central location. Which of the following should the administrator configure to ensure this requirement is met?

  A. Alerting
  B. Retention
  C. Shipping
  D. Rotation
  C. Shipping

  ---

  Explanation

  The administrator should configure log shipping to ensure compliance with the regulation. Log shipping is the process of automatically transferring log files from one location to another, typically from a remote server or device to a central log storage location. This ensures that all log files are stored in a central location, which is a requirement in this case.

  Alerting refers to sending notifications when specific events or conditions occur, but it does not relate to storing logs in a central location. Retention refers to how long log files are kept before they are deleted, which is important for compliance and audit purposes, but it does not directly address the requirement to store logs in a central location.

  Rotation refers to the practice of moving older log files to an archive location or deleting them, typically to free up space on the server, and does not address the requirement to store logs in a central location.

• Question 457:

  Following a recent power outage, a server on a server farm has been running slowly. A technician receives a ticket with a request to check for anything out of the ordinary. The technician sees an orange light on the front console of the server, indicating an error.

  Which of the following should the technician check next?

  A. CPU
  B. Power supply
  C. RAM
  D. RAID battery
  B. Power supply

• Question 458:

  Which of the following is an example of load balancing?

  A. Round robin
  B. Active-active
  C. Active-passive
  D. Failover
  A. Round robin

  ---

  Explanation

  Round robin is an example of load balancing. Load balancing is the method of distributing network traffic equally across a pool of resources that support an application. Load balancing improves application availability, scalability, security, and performance by preventing any single resource from being overloaded or unavailable. Round robin is a simple load balancing algorithm that assigns each incoming request to the next available resource in a circular order. For example, if there are three servers (A, B, C) in a load balancer pool, round robin will send the first request to server A, the second request to server B, the third request to server C, the fourth request to server A again, and so on.

• Question 459:

  Which of the following licensing models allows the greatest number of concurrent Windows VMS to run on a host for the lowest cost?

  A. per user
  B. per core
  C. Per instance
  D. Per concurrent user
  A. per user

  ---

  Explanation

  The answer to this question may depend on several factors, such as the number and type of Windows VMs, the number and type of host machines, the number and type of users, and the specific licensing terms and conditions of each licensing model. However, based on the information available from the web search results, one possible answer is per user. Per user licensing model is a licensing model that allows a user to access Windows VMs from any device, regardless of the number of devices or VMs. Per user licensing model is available for Windows 10 Enterprise E3/E5, Windows VDA E3/E5, and Microsoft 365 F3/E3/E5. Per user licensing model may offer the greatest number of concurrent Windows VMs to run on a host for the lowest cost if the following conditions are met: The user needs to access multiple Windows VMs from different devices, such as desktops, laptops, tablets, or smartphones. The user needs to access Windows VMs that run different versions or editions of Windows, such as Windows 10 Enterprise, Windows 10 Pro, or Windows 7 Enterprise. The user needs to access Windows VMs that run on different types of host machines, such as physical servers, virtual servers, or cloud servers. The user does not need to access Windows VMs that run on dedicated hardware or have specific performance or security requirements. According to the web search results1, per user licensing model costs $84 per user per year for Windows 10 Enterprise E3, $168 per user per year for Windows 10 Enterprise E5, $100.80 per user per year for Windows VDA E3, and $196.80 per user per year for Windows VDA E5.These prices are based on the Open License Program and may vary depending on the volume and agreement level2 Per core licensing model is a licensing model that requires a license for each core of the processor on the host machine that runs Windows VMs. Per core licensing model is available for Windows Server 2022 Datacenter and Standard editions. Per core licensing model may offer a lower cost than per user licensing model if the following conditions are met: The host machine has a low number of cores or a high core density. The host machine runs a high number of Windows VMs with low resource consumption. The host machine runs only Windows Server VMs with the same edition as the host machine. According to the web search results2, per core licensing model costs $6,155 for 16 core licenses for Windows Server 2022 Datacenter edition and $1,069 for 16 core licenses for Windows Server 2022 Standard edition.These pricesare suggested retail prices and may vary depending on the reseller2 Per instance licensing model is a licensing model that requires a license for each instance of Windows that runs on a host machine or a VM. Per instance licensing model is available for Windows Server 2022 Essentials edition and some older versions of Windows Server. Per instance licensing model may offer a lower cost than per user or per core licensing model if the following conditions are met: The host machine runs only one instance of Windows Server with low resource consumption. The host machine does not need to run any other VMs or applications. The host machine does not need any advanced features or functions that are available in Datacenter or Standard editions. According to the web search results2, per instance licensing model costs $501 for one server license for Windows Server 2022 Essentials edition.This price is suggested retail price and may vary depending on the reseller2 Per concurrent user licensing model is a licensing model that allows a certain number of users to access Windows VMs at the same time, regardlessof the number of devices or VMs. Per concurrent user licensing model is not available for any current version of Windows or Windows Server. Per concurrent user licensing model was available for some older versions of Windows Server Terminal Services or Remote Desktop Services, but it was discontinued due to complexity and compliance issues. Therefore, per concurrent user licensing model cannot be used for running Windows VMs on a host.

• Question 460:

  A systems administrator needs to configure a new server and external storage for a new production application environment. Based on end-user specifications, the new solution needs to adhere to the following basic requirements:

  1.The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected.

  2.Application data IOPS performance is a must.

  3.Data availability is a high priority, even in the case of multiple hard drive failures.

  Which of the following are the BEST options to comply with the user requirements? (Choose three.)

  A. Install the OS on a RAID 0 array.
  B. Install the OS on a RAID 1 array.
  C. Configure RAID 1 for the application data.
  D. Configure RAID 5 for the application data.
  E. Use SSD hard drives for the data application array.
  F. Use SATA hard drives for the data application array.
  G. Use a single JBOD for OS and application data.
  B. Install the OS on a RAID 1 array.
  C. Configure RAID 1 for the application data.
  E. Use SSD hard drives for the data application array.

  ---

  Explanation

  1.The OS must be installed in a separate disk partition. In case of hard drive failure, it cannot be affected. = RAID 1

  2.Application data IOPS performance is a must. = SSD

  3.Data availability is a high priority, even in the case of multiple hard drive failures.= RAID 1, RAID 6 writes parity information across the drives as is done in RAID 5, but it writes two stripes, which allows the system to recover from two drive failures whereas RAID 5 cannot.
