Question 1

Which statement is true about the Block Storage?

Accepted Answer

B

Explanation: Block storage is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. When data is moved to block storage, the underlying SAN technology breaks the data into separate, uniform-sized pieces, or blocks. Each block will be given a unique identifier. The SAN will then place those blocks onto the physical storage, distributing them across several disks, often making multiple copies. When a user or application requests data from a block storage system, the underlying SAN technology reassembles the data blocks and presents the data to the user or application. Block storage decouples data from user environments. It allows data to be spread and duplicated across multiple storage devices, enabling faster retrieval and higher resilience to disk failures. Benefits: Provides the lowest latency: Block storage provides the lowest latency for network-based storage versus local disk drives in the server, Provide IOPS up to 48,000 IOPS. High performing: Block storage is highly available and independent of the clients that access it. It remains available and durable regardless of client outages. High redundancy: Network-based block storage is considered to have a higher level of redundancy compared to local disk storage. Endurance and Performance tiers: Block storage has two tiers from which to choose. Volumes can be created from 20 GB to 12 TB in size. Eight authorized hosts: Block storage allows eight authorized hosts (can request up to 64) to connect via the multipath IO (MPIO) iSCSI connection. Snapshots: Block storage allows point-in-time non-disruptive “snapshots,” which can be replicated to a cross-regional data center as a duplicate volume. Custom costs: Block storage allows monthly and hourly billing cycles. Data-at-rest encryption: Block storage offers provider-managed encryption-at-rest. Note: Customer- managed encryption is not supported by IBM Classic Storage; however, customer-managed encryption keys can be stored Use Cases: ⦾ many organizations use it for transactional databases. ⦾ As you have learned, block storage has a high performance and is easily updatable. Therefore, emails. ⦾ Because of its high performance and reliability, block storage is a common solution for storing Block storage suitable for low latency workloads where consistently high speeds required.

Question 2

Which of the following statement is correct for IAM?

Accepted Answer

D

Explanation: Identity and access management, or IAM is used to control access to resources.

Question 3

What is true about virtual private cloud (VPC) access control list?

Accepted Answer

D

Explanation: An Access Control List (ACL) can manage (that is, it can allow or deny) inbound and outbound traffic for a subnet. An ACL is stateless, which means that inbound and outbound rules must be specified separately and explicitly. Each ACL consists of rules, based on a source IP, source port, destination IP, destination port, and protocol. Every VPC has a default ACL that allows all inbound and outbound traffic. You can edit the default ACL rules, or create a custom ACL and attach it to your subnets. A subnet can only have one ACL attached to it at any time, but one ACL can be attached to multiple subnets. To make your ACLs effective, create rules that determine how to handle your inbound and outbound network traffic. With inbound rules, you can allow or deny traffic from a source IP range, with specified protocols and ports. With outbound rules, you can allow or deny traffic to a destination IP range, with specified protocols and ports. ACL rules are prioritized and considered in sequence. Higher priority rules are evaluated first and override lower priority rules. Inbound rules are separated from outbound rules. If no rules are specified, then implicit deny is the default behavior.

Question 9

A developer has written javaScript and deployed it to edge functions on IBM cloud internet services. What would cause the code to run?

Accepted Answer

B

Explanation: IBM Cloud® Internet Services Edge functions allow you to create or modify existing applications, without having to configure or maintain infrastructure, by using a serverless execution environment. Edge functions run on CIS edge servers, not in the user’s browser. That means you can trust that your code runs in a trusted environment where it cannot be bypassed by malicious clients. It also means that the user does not need to be using a modern browser that supports service workers – you can even intercept requests from API clients that aren't browsers. Edge Functions allows you to run code closer to users of your public-facing applications or websites. In turn, you can improve your application's performance and reduce latency. This means you can quickly create new applications or modify existing ones without having to configure or maintain infrastructure via our serverless execution environment. Once a new application is deployed or an existing application is modified, it takes us ~15 seconds to get the changes distributed globally to our 180+ PoPs worldwide.
