CV0-003 Exam Questions Tutorials

Enable MFA with a one-time password. MFA stands for multi-factor authentication, which is a method of verifying a user’s identity by requiring two or more forms of authentication. A one-time password (OTP) is a code that is generated randomly and valid only for a short period of time. By enabling MFA with OTP, the administrator can make access to the SaaS email more secure without changing the password policy, as users will need to provide both their password and an OTP to sign in.

A CDN (content delivery network) is a system of distributed servers that deliver web content to users based on their geographic location, the origin of the web page, and the content delivery server1. A CDN can improve the user experience by reducing the latency, bandwidth, and load on the origin server. By offloading the images to an object storage, such as Google Cloud Storage or Amazon S3, the web application can save costs and improve performance by storing and serving the images from a CDN edge location that is closer to the user2. A CDN can also provide caching, compression, and security features for the web content3.

The most important consideration when attempting to calculate the licensing costs for a piece of software that applies licensing fees on a socket-based model is the number of CPUs in the server. A socket-based model is a type of licensing model that charges based on the number of physical CPU sockets or slots on the server, regardless of how many cores or threads each CPU has. The systems administrator should count how many CPUs are installed on each server and multiply that by the licensing fee per socket to determine the total licensing cost for the software.

The best way to prevent two virtual database servers from being on the same host is to configure anti-affinity. Anti-affinity is a feature that allows specifying which VMs or applications should not run on the same host or cluster. This can improve availability, performance, and security by avoiding resource contention, single point of failure, or interference between VMs or applications. The systems administrator should create an anti-affinity rule or policy for the two virtual database servers to ensure they are placed on different hosts.
