S2000-020 sample questions

Question 1

True or False: When running an Oracle database on a Power Virtual Server instance with a shared processor pool, Oracle licensing must be based on the total number of physical cores in the entire server frame, regardless of the LPAR's entitled capacity.

Accepted Answer

False

Answer

True

Question 2

A company needs to migrate a 5TB AIX database from their on-premises Power8 server to a Power Virtual Server instance. The primary business requirement is to minimize application downtime to less than one hour. The company has a 10 Gbps Direct Link connection. Which migration method is most suitable to meet this downtime requirement?

Accepted Answer

Setting up a new PowerVS instance and using AIX logical volume mirroring (LVM mirroring) combined with a data replication tool over the Direct Link.

Answer

Using PowerVC to capture an image of the on-premises LPAR and deploying it from the image catalog in PowerVS.

Answer

Using IBM Cloud Mass Data Migration service to ship the physical disks to the IBM Cloud data center.

Answer

Using mksysb to create a full system backup, transferring it to IBM Cloud Object Storage, and restoring it to a new PowerVS instance.

Question 3

An administrator is deciding between a shared and a dedicated processor pool for a new Power Virtual Server instance that will run a performance-sensitive, licensed software product. The software license is tied to the number of processor cores. What is the primary trade-off between using a shared uncapped processor pool versus a dedicated processor pool in this scenario? ```mermaid graph TD subgraph On-Premises App[Licensed App] end subgraph PowerVS A[Shared Pool LPAR] B[Dedicated Pool LPAR] end App -->|Migrate to| A App -->|Migrate to| B A -- "Cost vs Performance" --> C{Decision} B -- "Cost vs Performance" --> C ```

Accepted Answer

Shared pool offers lower cost and the ability to burst above entitled capacity, but provides inconsistent performance. Dedicated pool guarantees performance but is more expensive.

Answer

Shared pool is only available for Linux workloads, while dedicated pool is required for AIX and IBM i.

Answer

Shared pool requires licensing the entire physical server, while dedicated pool allows sub-capacity licensing.

Answer

Shared pool does not support Live Partition Mobility (LPM), while dedicated pool does.

Question 4

When deploying a high-availability solution for an AIX application using PowerHA SystemMirror across two Power Virtual Server instances in the same data center, what is a critical network configuration requirement for the cluster heartbeat?

Accepted Answer

A dedicated private subnet must be configured for the heartbeat traffic, separate from the service and data replication networks.

Answer

The heartbeat network must be configured on a public subnet to ensure reachability.

Answer

The heartbeat must use the same network interface as the primary service IP address.

Answer

All cluster communication, including heartbeat, must be routed through an IBM Cloud Transit Gateway.

Question 5

A security administrator is tasked with hardening a new IBM i instance on Power Virtual Server to meet corporate compliance standards. The standards require data-at-rest encryption using company-managed keys and strict network access control. Which IBM Cloud services must be configured to meet these requirements? (Select TWO)

Accepted Answer

An operating system-level firewall on the IBM i instance

Accepted Answer

IBM Key Protect

Answer

IBM Cloud Certificate Manager

Answer

IBM Cloud Activity Tracker

Answer

IBM Cloud Security Groups

Question 6

A financial services client needs to deploy a new AIX-based application that processes sensitive customer data. Due to strict regulatory compliance (e.g., PCI DSS), they must ensure that their compute environment is physically isolated from other tenants. Which Power Virtual Server offering is designed to meet this requirement?

Accepted Answer

Deploying the LPAR on a dedicated host.

Answer

Configuring the LPAR with dedicated processors.

Answer

Placing the LPAR on a private VLAN.

Answer

Using a shared processor pool with capped LPARs.

Question 7

An enterprise is adopting a hub-and-spoke network topology to connect their on-premises data center and three separate Power Virtual Server workspaces, each in a different department. They require that all traffic between the spokes (the PowerVS workspaces) must be routed through a central virtual firewall for inspection. Which IBM Cloud service is essential for implementing this architecture?

Accepted Answer

IBM Cloud Transit Gateway

Answer

IBM Cloud Direct Link

Answer

VPC VPN Gateway

Answer

IBM Cloud Load Balancer

Question 8

What is a primary value proposition of running traditional IBM i workloads on Power Virtual Server compared to re-platforming them onto an x86-based cloud infrastructure?

Accepted Answer

It allows companies to move their IBM i applications to the cloud without code changes, recompilation, or extensive re-training.

Answer

It integrates natively with serverless computing platforms like AWS Lambda or Azure Functions.

Answer

It provides a lower entry cost for compute resources than any x86 cloud provider.

Answer

It offers a broader selection of third-party software in its marketplace than x86 cloud platforms.

Question 9

**Company Background:** A major North American e-commerce company operates its primary AIX-based order processing system in the IBM Cloud PowerVS data center in Toronto (TOR). The system is business-critical, and any downtime results in significant revenue loss. The company's board has mandated a robust disaster recovery (DR) solution to protect against a regional outage. **Current Situation:** The Toronto environment consists of several PowerVS LPARs on a private network (10.10.10.0/24). This network is connected to their corporate headquarters via a 2 Gbps Direct Link. The company has chosen the Montreal (MON) data center as their DR site. **Requirements:** 1. A DR environment must be established in the Montreal PowerVS data center. 2. The DR network in Montreal must be on a non-overlapping private subnet (10.20.20.0/24). 3. Data must be replicated between Toronto and Montreal with an RPO of seconds. 4. In a DR event, corporate headquarters must be able to securely access the failed-over LPARs in Montreal over a private connection. 5. The solution should avoid routing DR traffic over the public internet. Which network architecture best fulfills all these DR connectivity requirements?

Accepted Answer

Deploy an IBM Cloud Transit Gateway with local routing. Connect the Direct Link, the Toronto PowerVS workspace, and the Montreal PowerVS workspace to the Transit Gateway. Use Global Mirror for data replication over this private backbone.

Answer

Establish a new, separate Direct Link from headquarters to Montreal. Use storage-level replication (Global Mirror) over the public internet between TOR and MON for data replication.

Answer

Set up a site-to-site VPN tunnel between the Toronto and Montreal PowerVS workspaces for data replication. In a DR event, manually reconfigure the Direct Link BGP session to advertise the Montreal subnets.

Answer

Use IBM Cloud Internet Services (CIS) Global Load Balancer to manage failover. Replicate data using an application-level tool over the public network. Access the DR site using its public IP addresses.

Question 10

True or False: Live Partition Mobility (LPM) is a feature that allows a running Power Virtual Server LPAR to be moved between two different physical servers within the same data center without downtime, and this process is automatically managed by the IBM Cloud control plane.

Accepted Answer

False

Answer

True
