• Question 302:

  An administrator notices that a file server is filling up quickly but has many of the same files in different directories. Which of the following storage management techniques would resolve this issue?

  A. Provisioning
  B. Encryption
  C. Deduplication
  D. Partitioning
  C. Deduplication

  ---

  Explanation

  The storage management technique that would resolve this issue is deduplication.

  Deduplication is a technique that identifies and eliminates duplicate copies of data in a storage system. This reduces the amount of storage capacity needed and can improve backup and restore times. In this scenario, since the file server has

  many of the same files in different directories, deduplication can identify those duplicate files and store only one copy, freeing up space on the server.

  Option A, provisioning, refers to the process of allocating and managing storage resources for a particular application or service.

  Option B, encryption, is a technique used to protect data by encoding it in such a way that only authorized users can read it.

  Option D, partitioning, is the process of dividing a physical storage device into multiple logical units, each of which can be used independently. This can be useful for organizing data or separating operating system files from user files, but it

  does not address the issue of duplicate files taking up storage space.

• Question 303:

  A server technician installs a new NIC on a server and configures the NIC for IP connectivity. The technician then tests the connection using the ping command. Given the following partial output of the ping and ipconfig commands:

  

  Which of the following caused the issue?

  A. Duplicate IP address
  B. Incorrect default gateway
  C. DHCP misconfiguration
  D. Incorrect routing table
  A. Duplicate IP address

  ---

  Explanation

  The ping command output shows that the NIC has an IP address of 192.168.1.100 and a default gateway of 192.168.1.1. However, when the technician tries to ping the default gateway, the reply comes from another IP address:

  192.168.1.101. This means that there is another device on the network that has the same IP address as the default gateway, and it is responding to the ping request instead of the intended destination. A duplicate IP address can cause network connectivity problems, such as packet loss, routing errors, or unreachable hosts. To resolve this issue, the technician should either change the IP address of the default gateway or the device that is conflicting with it, or use DHCP to assign IP addresses automatically and avoid conflicts. The other options are not correct because they do not explain the ping output. An incorrect default gateway would cause no reply or a destination unreachable message, not a reply from a different IP address. A DHCP misconfiguration would cause an invalid or no IP address on the NIC, not a duplicate IP address on the network. An incorrect routing table would cause routing errors or unreachable destinations, not a reply from a different IP address.

• Question 304:

  A systems administrator is setting up a new server that will be used as a DHCP server. The administrator installs the OS but is then unable to log on using Active Directory credentials. The administrator logs on using the local administrator account and verifies the server has the correct IP address, subnet mask, and default gateway. The administrator then gets on another server and can ping the new server. Which of the following is causing the issue?

  A. Port 443 is not open on the firewall
  B. The server is experiencing a downstream failure
  C. The local hosts file is blank
  D. The server is not joined to the domain
  D. The server is not joined to the domain

  ---

  Explanation

  The server is not joined to the domain is causing the issue. A domain is a logical grouping of computers that share a common directory database and security policy on a network. Active Directory is a Microsoft technology that provides domain services for Windows- based computers. To use Active Directory credentials to log on to a server, the server must be joined to the domain that hosts Active Directory. If the server is not joined to the domain, it will not be able to authenticate with Active Directory and will only accept local accounts for logon. To join a server to a domain, the administrator must have a valid domain account with sufficient privileges and must know the name of the domain controller that hosts Active Directory.

• Question 305:

  Users at a company work with highly sensitive data. The security department implemented an administrative and technical control to enforce least-privilege access assigned to files. However, the security department has discovered unauthorized data exfiltration.

  Which of the following is the BEST way to protect the data from leaking?

  A. Utilize privacy screens.
  B. Implement disk quotas.
  C. Install a DLP solution.
  D. Enforce the lock-screen feature.
  C. Install a DLP solution.

  ---

  Explanation

  The best way to protect the data from leaking is to install a DLP solution. A DLP (Data Loss Prevention) solution is a software that helps businesses prevent confidential data from being leaked or stolen by unauthorized parties. A DLP solution can identify, monitor, and protect data as it moves across networks and devices, such as endpoints, email, web, cloud applications, or removable media. A DLP solution can also enforce security policies based on content and context for data in use, in motion, and at rest. A DLP solution can detect and prevent data breaches by using various techniques, such as content inspection, contextual analysis, encryption, blocking, alerting, warning, quarantining, or other remediation actions.

• Question 306:

  A technician discovers a Linux server cannot mount an NFS share. The following error message occurs after a mount server: /test /mnt/test command: mount point /mnt/test does not exist. Which of the following should the technician perform FIRST?

  A. Execute ping server.
  B. Execute mkdir -p /mnt/test.
  C. Ensure the server rewall is turned off.
  D. Ensure server: /test is an exported NFS share.
  B. Execute mkdir -p /mnt/test.

• Question 307:

  An analyst is planning a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. The analyst would like the fastest possible connection speed. Which of the following would best meet the analyst's needs?

  A. 1000BASE-LX 1Gb single-mode plenum fiber connection
  B. 10GBASE-T 10Gb copper plenum Ethernet connection
  C. 1000BASE-T 1Gb copper non-plenum Ethernet connection
  D. 10GBASE-SR 10Gb multimode plenum fiber connection
  A. 1000BASE-LX 1Gb single-mode plenum fiber connection

  ---

  Explanation

  A 1000BASE-LX 1Gb single-mode plenum fiber connection would best meet the analyst's needs for a new point-to-point Ethernet connection between a university campus and a newly acquired space downtown that is about 5mi (8km) away. A 1000BASE-LX is a type of Ethernet standard that supports data transmission at 1 gigabit per second over single- mode fiber cables using long wavelength lasers. A single-mode fiber cable is a type of optical fiber cable that has a small core diameter and allows only one mode of light to propagate through it. A single-mode fiber cable can transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A plenum fiber cable is a type of optical fiber cable that has a special coating that prevents the spread of fire or toxic fumes in case of burning. A plenum fiber cable is suitable for installation in plenum spaces, which are areas used for air circulation in buildings, such as above ceilings or below floors.

  A. Per socket
  B. Open-source
  C. Per concurrent user
  D. Volume
  D. Volume

  ---

  Explanation

  This is the most likely licensing type that will be used because volume licensing allows a single license key to be used for multiple installations of a software product. Volume licensing is typically used by organizations that need to deploy software to a large number of devices or users.

• Question 310:

  Corporate policy mandates that logs from all servers be available for review regardless of the state of the server. Which of the following must be configured to comply with this policy?

  A. Aggregation
  B. Subscription
  C. Merging
  D. Collection
  A. Aggregation

  ---

  Explanation

  Aggregation is the process of collecting, standardizing, and consolidating log data from multiple sources into a central location. Aggregation makes it easier to search, analyze, and report on log data, as well as to comply with security policies and regulations. By aggregating logs from all servers, regardless of their state, the corporate policy can ensure that no log data is lost or inaccessible in case of a server failure or outage
