CompTIA CompTIA Certifications SK0-005 Questions & Answers

• Question 431:

  An administrator has been asked to verify that all traffic egressing from a company is secured. The administrator confirms all the information that is sent over the network is encrypted. Which of the following describes the type of traffic being encrypted?

  A. Network encapsulation

  B. Off-site data

  C. Secure FTP

  D. Data in transit

  Correct Answer: D

  Explanation: Data in transit is data that is being transferred over a network, such as the internet. It can be encrypted to protect it from unauthorized access or tampering. Verified References: [Data in transit], [Encryption]

• Question 432:

  The accounting department needs more storage and wants to retain the current data for quick read-write access. The accounting server does not have any internet drive bays available to keep both disks however the server does have USB 3 0 and eSATA ports available. Which of the following is the BEST way to accomplish the department's goals?

  A. Copy the existing data to an external USB 3 0 enclosure.

  B. Place the existing data on a DVD and use the internal DVD-ROM drive.

  C. Transfer the existing data to an external eSATA enclosure.

  D. Move the existing data to a new. larger internal hard drive.

  Correct Answer: C

  Explanation: The best way to accomplish the department's goals is to transfer the existing data to an external eSATA enclosure, which is a device that connects an external hard drive to a computer using an eSATA port. This will allow the accounting department to retain the current data for quick read-write access, as eSATA provides high-speed data transfer rates and supports hot-plugging. Unlike USB 3.0, eSATA does not share bandwidth with other devices, which can improve performance and reliability. Verified References: [eSATA vs USB 3.0]

• Question 433:

  An administrator is tasked with building an environment consisting of four servers that can each serve the same website. Which of the following concepts is described?

  A. Load balancing

  B. Direct access

  C. Overprovisioning

  D. Network teaming

  Correct Answer: A

  Load balancing is a concept that distributes the workload across multiple servers or other resources to optimize performance, availability, and scalability. Load balancing can be implemented at different layers of the network, such as the

  application layer, the transport layer, or the network layer. Load balancing can use various algorithms or methods to determine how to distribute the traffic, such as round robin, least connections, or weighted distribution.

• Question 434:

  An organization is donating its outdated server equipment to a local charity. Which of the following describes what the organization should do BEFORE donating the equipment?

  A. Remove all the data from the server drives using the least destructive method.

  B. Repurpose and recycle any usable server components.

  C. Remove all the components from the server.

  D. Review all company polices.

  Correct Answer: D

  Explanation: Before donating the outdated server equipment to a local charity, the organization should review all company policies regarding data security, asset disposal, and social responsibility. This can help ensure that the donation complies with the legal and ethical standards of the organization and does not pose any risk to its reputation or operations.

• Question 435:

  An organization recently experienced power outages. The administrator noticed the server did not have enough time to shut down properly. After the outages, the administrator had additional batteries installed in the UPS. Which of the following best describes the solution the administrator implemented?

  A. The solution reduced shutdown time.

  B. The solution improved load balancing,

  C. The solution increased power out.

  D. The solution extended runtime.

  Correct Answer: D

  The solution the administrator implemented extended runtime. Runtime is the amount of time that a UPS can provide backup power to a server in case of a power outage. By installing additional batteries in the UPS, the administrator increased the capacity and duration of the backup power, allowing the server more time to shut down properly.

• Question 436:

  An administrator is deploying a new secure web server. The only administration method that is permitted is to connect via RDP. Which of the following ports should be allowed? (Select TWO).

  A. 53

  B. 80

  C. 389

  D. 443

  E. 45

  F. 3389

  G. 8080

  Correct Answer: DF

  Port 443 is the default port for HTTPS, which is the protocol used for secure web communication. HTTPS uses SSL/TLS certificates to encrypt the data between the web server and the browser. Port 443 is commonly used for web servers that need to provide secure services, such as online banking, e-commerce, or email. By allowing port 443, the administrator can access the web server's interface and manage its settings1. Port 3389 is the default port for RDP, which is the protocol used for remote desktop connection. RDP allows a user to remotely access and control another computer over a network. Port 3389 is commonly used for remote administration, technical support, or remote work. By allowing port 3389, the administrator can connect to the web server's desktop and perform tasks that require graphical user interface2.

• Question 437:

  A server administrator is installing a new server with multiple NICs on it. The Chief Information Officer has asked the administrator to ensure the new server will have the least amount of network downtime but a good amount of network speed. Which of the following best describes what the administrator should implement on the new server?

  A. VLAN

  B. vNIC

  C. Link aggregation

  D. Failover

  Correct Answer: C

  Link aggregation is the best option to implement on the new server to ensure the least amount of network downtime but a good amount of network speed. Link aggregation is a technique of combining multiple physical network interfaces into one logical interface to increase bandwidth, redundancy, and load balancing. Link aggregation can improve the performance and availability of the server by allowing it to use more than one network path for data transmission and failover in case of link failure. Link aggregation can be implemented using various protocols, such as IEEE 802.3ad (LACP), Cisco EtherChannel, or Linux bonding.

• Question 438:

  A systems administrator notices a newly added server cannot see any of the LUNs on the SAN. The SAN switch and the local HBA do not display any link lights. Which of the following is most likely the issue?

  A. A single-mode fiber cable is used in place of multimode.

  B. The switchport is on the wrong virtual SAN.

  C. The HBA driver needs to be installed on the server.

  D. The zoning on the fiber switch is wrong.

  Correct Answer: A

  The most likely issue that prevents the newly added server from seeing any of the LUNs on the SAN is that a single-mode fiber cable is used in place of multimode. 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 cablecan transmit data over long distances at high speeds, but it requires more expensive transceivers and connectors than multimode fiber cables. A multimode fiber cable is a type of optical fiber cable that has a larger core diameter and allows multiple modes of light to propagate through it. A multimode fiber cable can transmit data over short distances at lower speeds than single- mode fiber cables, but it is more compatible and cost-effective than single-mode fiber cables. If a single-mode fiber cable is used in place of multimode, it can cause signal loss, attenuation, or mismatch between the devices.

• Question 439:

  Hackers recently targeted a company with an attack that resulted in a system breach, which compromised the organization's data. Because of the system breach, the administrator had to bypass normal change management procedures. Which of the following change management activities was necessary?

  A. Cancelled change request

  B. Change request postponement

  C. Emergency change request

  D. Privilege change request

  E. User permission change request

  Correct Answer: C

  Explanation: An emergency change request is a type of change management activity that is used to address urgent issues that pose a significant risk to the organization, such as a system breach. An emergency change request requires immediate action and approval, and it may bypass some of the normal change management procedures, such as testing, documentation, or stakeholder communication12.
