Version control software offers numerous benefits to development teams. Key advantages include:

Comparisons between revisions of source code files: Version control allows developers to compare different versions of source code files, track changes, and identify what modifications were made and by whom. This is essential for debugging and maintaining code quality.

Access to current code and history for new team members: New team members can quickly get up to speed by accessing the current version of the code and the entire history of changes. This transparency facilitates onboarding and improves collaboration among team members.

Virtual machines (VMs) run directly on a hypervisor, which abstracts and manages the underlying hardware resources.

Hypervisor: A hypervisor, also known as a Virtual Machine Monitor (VMM), allows multiple VMs to run on a single physical machine by providing an abstraction layer between the VMs and the hardware.

VMs: Each VM operates as a separate entity with its own operating system and applications, isolated from other VMs.

Clients make several types of queries to DNS servers. The two relevant types here are:

AAAA: This query type requests the IPv6 address associated with a domain name.

PTR: This query type is used for reverse DNS lookups, where it maps an IP address to a domain name.

AAAA (Quad-A) records store IPv6 addresses of a domain.

PTR (Pointer) records are used in reverse DNS lookups to map IP addresses to the corresponding domain names.

A network interface hardware address, also known as a MAC (Media Access Control) address, is a unique identifier assigned to network interfaces for communications on the physical network segment.

Domain name: A human-readable address for network resources.

IP address: A logical address used for identifying devices on a network.

Workstation name: A human-readable name assigned to a computer.

MAC address: The correct answer, which is a hardware address assigned to a network interface.

DevOps emphasizes collaboration between development and operations teams, breaking down organizational silos to improve workflow and communication (C). Additionally, DevOps focuses on automating processes to increase efficiency, reduce manual effort, and minimize errors, often prioritizing automation over extensive documentation (E).

Option A correctly creates a handle instance using the UcsHandle class from the UCS SDK in Python. The correct instantiation requires providing the IP address, username, password, port number, and secure connection parameters as per the documented API.

The correct code snippet is:

from ucsmsdk.ucshandle import UcsHandle

handle = UcsHandle("10.1.2.254", "admin", "password", port="443", secure=True)

This snippet matches the API documentation requirements:

ip: The IP or hostname of the UCS Server.

username: The username as configured on the UCS Server.

password: The password as configured on the UCS Server.

port: The port number to be used during the connection.

secure: True for a secure connection.
