Which of the following is most likely to work with an FC connection and offers more scalability?
Answer: B
B. SAN (Storage Area Network). Explanation: SAN (Storage Area Network) is most likely to work with an FC (Fibre Channel) connection, which is a high-speed network technology commonly used in storage environments. SANs are designed to provide centralized, high-performance storage that can be accessed by multiple servers over a network. SANs offer excellent scalability because new storage devices or servers can be easily added to the network without disrupting the existing setup.

A company is moving to a hybrid cloud model. As part of this move the mail server will be moved to the cloud. The systems administrator needs to ensure the mail server continues to receive email. Which of the following types of DNS records should the systems administrator update?
Answer: C
C. MX (Mail Exchange). Explanation: MX (Mail Exchange) records in DNS specify the mail servers responsible for receiving email messages for a domain. When moving the mail server to the cloud, the systems administrator must update the MX record to point to the new cloud-based mail server’s address. This ensures that email messages are routed to the correct server.

A network engineer is configuring network ports in a public office. To increase security, the engineer wants the ports to allow network connections only after authentication. Which of the following security features should the engineer use?
Answer: B
A network administrator is expanding a network and wants to ensure no unauthorized redundant links are present. Which of the following should the administrator use to identify and block redundant links?
Answer: B
A network administrator notices uncommon communication between VMs on ephemeral ports on the same subnet. The administrator is concerned about that traffic moving laterally within the network. Which of the following describes the type of traffic flow the administrator is analyzing?
Answer: A
A. East-west traffic Any network activity that moves between systems within the data center. Network devices seen in east-west traffic include internal routers, internal firewalls, and switches.

Which of the following would be violated if an employee accidentally deleted a customer's data?
Answer: D
Availability ensures that data and services are accessible when needed. If an employee accidentally deletes a customer's data, that data becomes unavailable, violating this principle. Integrity (A) refers to the accuracy and trustworthiness of data. While deletion affects access, it does not necessarily compromise data integrity. Confidentiality (B) involves protecting data from unauthorized access. Accidental deletion does not expose the data to unauthorized users. Vulnerability (C) is a weakness in a system that could be exploited but is not a security principle itself.

A network engineer is now in charge of all SNMP management in the organization. The engineer must use a SNMP version that does not utilize plaintext data. Which of the following is the minimum version of SNMP that supports this requirement?
Answer: D
SNMP v1 (A) and SNMP v2c (B) both use plaintext community strings for authentication, making them insecure. SNMP v2u (C) introduced some security improvements but was never widely adopted. SNMP v3 (D) is the first version to support encryption and authentication, ensuring that data is not transmitted in plaintext. It includes features like message integrity, authentication, and encryption (privacy) through protocols such as HMAC-MD5, HMAC-SHA, and AES/DES encryption.

A company recently acquired a number of sites and no documentation was provided. A network administrator needs to identify and document all of the digital assets in use. Which of the following is the best method for the administrator to use?
Answer: D
Network discovery is the process of identifying and locating all devices connected to a network, allowing systems to find each other and communicate, essentially creating a map of the network infrastructure by identifying every device, its connection points, and overall network structure; this helps network administrators manage device inventories, enforce access policies, and maintain better control over the network. How it works: Devices on a network send out messages to discover other active devices, allowing them to identify and connect with each other.
