SRE is a novel method that can help with system administration and problem-solving. This concept can be viewed as a novel approach to system administration. To help you prepare for your upcoming ITIL interview, we've compiled a list of the DevOps SRE FOUNDATION Certification Exam questions and answers.
SRE Foundation Certification Exam Sample Questions
1. Describe the data structure. Give a data structure a name.
A data framework is essential for storing, organizing, and manipulating data for easy access and modifications. A data structure, more appropriately, is a collection of data values, their relationships, and the functions or operations that you may perform on the data.
The following are examples of data structures:
- Linear: Arrays, lists
- Tree: Binary, heaps
- Graphs: Decision, Acyclic, etc
- Hash: Distributed hash table, hash tree, etc
2. What exactly is DHCP, and how does it function?
The Dynamic Host Configuration Protocol (network management protocol) assigns a dynamic IP address and several network configuration settings to each device on an IP network, allowing them to communicate with other IP networks.
A DHCP server performs the following functions:
They automatically obtain IP addresses and networking data from the Internet service provider (ISP), reducing the need for a network.
3. Define the budget policy for Error?
When SLO indicates that a service is unreliable enough, an error budget policy demonstrates how a corporation decides to trade off dependability effort against other feature development.
4. What is the distinction between DevOps and SRE?
SRE is concerned with ensuring that all IT teams use the same technology and access the same data. DevOps focuses on technology adoption and automation. DevOps is primarily concerned with process performance and outcomes achieved through a feedback loop to accomplish continuous improvement. As SRE views Ops issues as software engineering issues, SLOs are the primary metric.
5. What exactly is an inode?
An inode is a Unix data structure for storing metadata about a file. The following are some of the items found in an inode:
- the owner (UID, GID)
- atime, ctime, time
6. What is observability, and how can businesses improve their systems' observability?
The term "observability" refers to a conversation regarding a company's measurement and instrumentation.
7. Do you know what TCP stands for? Please add some TCP connections to the list.
TCP arose from the early network deployment, which you can use to supplement the Internet Protocol (IP). TCP/IP is the abbreviation for Transmission Control Protocol/Internet Protocol.
8. How does cloud computing function, and what does it entail?
The on-demand availability of computer system resources, notably data storage (cloud storage) and computational power, is called cloud computing without the user's active administration. The term refers to data centers accessible to many people over the Internet. In today's big clouds, functions from central servers are frequently spread over multiple sites. It can be characterized as an edge server if the connection to the user is quite close.
9. What does it mean to "reduce toil"?
Some actions that can help you save time and effort are as follows:
- Creation of external automation
- Creating internal automation
- Improving the service to the point where it doesn't need to be maintained.
10. What is SLO?
An SLO, or Service Level Objective, is a significant component of a service-level agreement (SLA) between a service provider and a customer that is agreed upon to measure service providers' performance and is developed to avoid conflicts. There are two parties involved.
SLO refers to a measurable attribute of a service level agreement, such as availability, throughput, frequency, reaction time, or quality. These SLOs establish the expected level of service between the provider and the client, and they vary depending on the service's urgency, resources, and budget. SLOs are a numerical way of describing a consumer's level of service from a supplier.
