  Which of the following documents would be useful when trying to restore IT infrastructure operations after a non-planned interruption?

  A. Service-level agreement
  B. Disaster recovery plan
  C. Business impact analysis
  D. Business continuity plan
  B. Disaster recovery plan

  ---

  Explanation

  A disaster recovery plan would be useful when trying to restore IT infrastructure operations after a non-planned interruption. A disaster recovery plan is a document that outlines the steps and procedures to recover from a major disruption of

  IT services caused by natural or man-made disasters, such as fire, flood, earthquake, cyberattack, etc. A disaster recovery plan typically includes:

  A list of critical IT assets and resources that need to be protected and restored A list of roles and responsibilities of IT staff and stakeholders involved in the recovery process A list of backup and recovery strategies and tools for data,

  applications, servers, networks, etc.

  A list of communication channels and methods for notifying users, customers, vendors, etc.

  A list of testing and validation methods for ensuring the functionality and integrity of restored systems

  A list of metrics and criteria for measuring the effectiveness and efficiency of the recovery process

  A disaster recovery plan helps IT organizations to minimize downtime, data loss, and financial impact of a disaster, as well as to resume normal operations as quickly as possible.

• Question 403:

  Which of the following cloud models is BEST described as running workloads on resources that are owned by the company and hosted in a company-owned data center, as well as on rented servers in another company's data center?

  A. Private
  B. Hybrid
  C. Community
  D. Public
  B. Hybrid

  ---

  Explanation

  This is the best description of a hybrid cloud model because it combines both private and public cloud resources. A private cloud is a cloud environment that is owned and operated by a single organization and hosted in its own data center. A public cloud is a cloud environment that is owned and operated by a third-party provider and hosted in its data center. A hybrid cloud allows an organization to leverage both types of cloud resources depending on its needs and preferences.

• Question 404:

  A user is unable to access the database server from a workstation. All other workstations are able to access the database server. The technician issues the following command to check the workstation:

  userGhost:!# nmap localhost

  Nmap scan report for localhost (127.0.0.1)

  Host is up (0.001 ms latency).

  Not shown: 1023 closed ports

  PORT STATE SERVICE

  3306 open mysql

  Which of the following should the technician perform next to allow access?

  A. Check the database server
  B. Change the database password
  C. Open port 3306 on the server
  D. Edit the network firewall rules
  D. Edit the network firewall rules

  ---

  Explanation

  Sinceport 3306(MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to checknetwork firewall rules. It's possible that the workstation's firewall or network-level security rules are blocking outbound or

  inbound traffic on port 3306, which is required for database access.

  Edit the network firewall rules (Answer D):Ensuring the firewall allows traffic on port 3306 is the appropriate next step, especially since other workstations are not having the same issue. Checking the database server (Option A):This is

  unnecessary because other workstations can access the server, confirming the server itself is functioning correctly. Changing the database password (Option B):This would not resolve the issue of one workstation being unable to connect

  while others can.

  Opening port 3306 on the server (Option C):The problem isn't server-side since other machines can connect without issue.

• Question 405:

  A server is performing slowly, and users are reporting issues connecting to the application on that server. Upon investigation, the server administrator notices several unauthorized services running on that server that are successfully communicating to an external site. Which of the following are MOST likely causing the issue? (Choose two.)

  A. Adware is installed on the users' devices
  B. The firewall rule for the server is misconfigured
  C. The server is infected with a virus
  D. Intrusion detection is enabled on the network
  E. Unnecessary services are disabled on the server
  F. SELinux is enabled on the server
  B. The firewall rule for the server is misconfigured
  C. The server is infected with a virus

  Explanation

• Question 406:

  A security administrator ran a port scanning tool against a virtual server that is hosting a secure website. A list of open ports was provided as documentation. The management team has requested that non-essential ports be disabled on the firewall. Which of the following ports must remain open?

  A. 25
  B. 53
  C. 443
  D. 3389
  E. 8080
  C. 443

  Explanation

• Question 407:

  A server technician notices several of the servers in a data center are making loud noises. The servers are still working correctly, and no indicator lights show any issues. Which of the following should the technician do first to ensure the issues are corrected and the servers remain online?

  A. Replace the drives.
  B. Upgrade the firmware.
  C. Establish a remote connection to the server.
  D. Replace the fans.
  A. Replace the drives.

  ---

  Explanation

  The loud noises from the servers are most likely caused by failing hard disk drives, which can produce clicking or grinding sounds. Replacing the drives with new ones can prevent data loss and downtime. Replacing the drives can be done without shutting down the server if they are hot-swappable, which means they can be removed and inserted while the server is running.

• Question 408:

  A security technician generated a public/private key pair on a server. The technician needs to copy the key pair to another server on a different subnet. Which of the following is the MOST secure method to copy the keys?

  A. HTTP
  B. FTP
  C. SCP
  D. USB
  C. SCP

  Explanation

• Question 409:

  A server administrator is configuring a new server that will hold large amounts of information. The server will need to be accessed by multiple users at the same time. Which of the following server roles will the administrator MOST likely need to install?

  A. Messaging
  B. Application
  C. Print
  D. Database
  D. Database

  ---

  Explanation

  Few people are expected to use the database at the same time and users don't need to customize the design of the database.

  The server role that the administrator will most likely need to install for a server that will hold large amounts of information and will need to be accessed by multiple users at the same time is database. A database is a collection of structured

  data that can be stored, queried, manipulated, and analyzed using various methods and tools. A database server is a server that hosts one or more databases and provides access to them over a network. A database server can handle large

  amounts of information and support concurrent requests from multiple users or applications.

• Question 410:

  Winch of the following is a type of replication in which all files are replicated, all the time?

  A. Constant
  B. Application consistent
  C. Synthetic full
  D. Full
  A. Constant

  ---

  Explanation

  Constant replication is a type of replication in which all files are replicated, all the time. Replication is a process of copying data from one location to another for backup, recovery, or distribution purposes. Constant replication is also known as real-time replication or synchronous replication. It ensures that any changes made to the source data are immediately reflected on the target data without any delay or lag. Constant replication provides high availability and consistency, but it requires high bandwidth and low latency. Application consistent replication is a type of replication that ensures that the replicated data is consistent with the state of the application that uses it. It involves quiescing or pausing the application before taking a snapshot of the data and resuming the application after the snapshot is taken. Application consistent replication provides better recovery point objectives than crash consistent replication, which does not quiesce the application before taking a snapshot. Synthetic full replication is a type of replication that involves creating a new full backup by using the previous full backup and related incremental backups. It reduces the backup window and network bandwidth consumption by transferring only changed data from the source to the target. Full replication is a type of replication that involves copying all data from the source to the target regardless of whether it has changed or not. It provides a complete backup of the data, but it requires more storage space and network bandwidth than incremental or differential replication.
