Answer : A

Site reliability engineering (SRE) uses software engineering to automate IT operations tasks - e.g. production system management, change management, incident response, even emergency response - that would otherwise be performed manually by systems administrators (sysadmins). The principle behind SRE is that using software code to automate oversight of large software systems is a more scalable and sustainable strategy than manual intervention - especially as those systems extend or migrate to the cloud. SRE can also reduce or remove much of the natural friction between development teams who want to continually release new or updated software into production, and operations teams who don't want to release any type of update or new software without being absolutely sure it won't cause outages or other operations problems. As a result, while not strictly required for DevOps, SRE aligns closely with DevOps principles and can be play an important role in DevOps success

Answer : A

Watson Discovery unlocks hidden value in information to get answers, monitor trends, and repair patterns with the world's most advanced cloud-native insight engine. Watson Discovery Service enables you to ingest, normalize, enrich, index, search, and explore, your data, both structured and unstructured. Watson Discovery gives you the ability to, store, analyze, and understand your data at scale. First, Watson ingests and standardizes all of your data, no matter the type. Just load it and go. Watson then enriches your data using natural language understanding capabilities. Watson Discovery allows you to interrogate your data in either a natural language format or a query language that will search for both Boolean conditions and for phrases. Once the data is found, Watson Discovery uses machine learning algorithms to order the answers so that the most useful answers are listed first. Watson Discovery leverages the power of Watson to add deep content learning to your applications. One application of Watson Discovery is natural language documentation search.

Answer : D

You can use security groups to enact a set of IP filter rules that define how to handle incoming and outgoing traffic to both the public and private interfaces your instance. Use security groups when you order a virtual server. That way, your server is protected when it is first provisioned. Other Scenarios with solutions listed below : 1. Security scenario: Customers want granular control over traffic at an instance level (apart from network-level firewalls). However, at the same time, the costs of a shared hardware firewall can add up quickly if you need to protect multiple servers in different data centers. Solution: You do not incur extra charges for using security groups. You can use security groups for all virtual servers that need protection in any of our global data centers. 2. Security scenario: You want to avoid configuring firewall rules on each server separately. Instead, you want an easily manageable firewall solution that spans servers in different global data centers. Solution: Define N security groups for N different types of servers in your cloud workload. Manage all rules for a security group in one place. Manage the security group associations with the virtual servers.

Answer : A

Hybrid cloud is simply the combination of public and private cloud environments working together to run your applications or workloads. Key tenets of all hybrid clouds: interoperability, scalability, portability, and security.

Answer : C

Cold Vault (for cold data): Use this option for data accessed only a few times a year. A larger retrieval charge applies for reading data. Common use cases include long-term backup, large data set preservation, or older media content. Cold Vault includes a threshold for object size and storage period with a minimum billable object size of 256 KB and a minimum storage duration of 90 days. Objects smaller than the minimum size will incur a charge for the minimum billable object size. In-Correct Answers : Standard (for active data) : Use this level for active data that's accessed multiple times a month. Your data is immediately available when needed. Common use cases include streaming mobile and web content, DevOps, analytics, collaboration and active content repositories. There are no retrieval charges, no minimum object size and no minimum duration requirement. Vault (for less active data): Use this level for less active data that's accessed once a month or less. Data is immediately available when needed. A low retrieval charge applies for reading data. Common use cases include backup and digital asset retention. Vault includes a threshold for object size and storage period with a minimum billable object size of 128 KB and a minimum storage duration of 30 days. Hot Tier : Hot tier is built in tier type of Smart tier.With Smart Tier, you no longer have to worry about selecting the right storage class for your workloads. Smart Tier will track your monthly activity and bill you one monthly capacity rate from three built-in pricing tiers: hot, cool, or cold. Smart Tier: Smart Tier employs automatic cost optimization to ensure that you get the lowest storage cost each month. This is valuable for all workloads, especially ones with variable or unpredictable data access patterns and ones that change over time.
