Question # 36
Which part of IBM cloud park foundational services provides cluster administrators an at-a-glance overview of a cluster?
The IBM Cloud Pak® foundational services console includes an Administration Hub dashboard that provides Cluster Administrators an at-a-glance overview of a cluster. From this UI dashboard, you can view key metrics for specific components of IBM Cloud Pak for Security and the IBM Cloud Pak foundational services that are deployed to the cluster. The Administration Hub is available by default. It is deployed automatically as a part of the installation of IBM Cloud Pak for Security and IBM Cloud Pak foundational services. The Administration Hub can be accessed from the main navigation menu of the foundational services console and clicking Home.
Question # 37
Which cloud storage have poor performance when data needs to be shared ?
Direct area storage, also known as direct-attached storage (DAS), is as the name implies. DAS is a storage device which directly connected to your computer or server, if often connected to a single machine only. Some examples of direct attached storage are floppy disks, optical disc, compact discs (CDs) and digital video discs (DVDs), hard disk drives (HDD), flash drives and solid-state drives (SSD). DAS is often connected with single computing machine only so sharing capabilities are limited and poor. Block storage is highly available and resilient and will often include data encryption at rest and in transit. 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. Block storage suitable for low latency workloads where consistently high speeds required. File Storage associated with Network Attached Storage (NAS) technology. File Storage organizes files in a hierarchy of named directories. The ability for File Storage to be mounted to multiple compute nodes at a time make it an ideal solution for common storage requirements. Object Storage enable you to store and access unstructured data anywhere in the world with a self-service portal backed by RESTful APIs. Object Storage supports exponential data growth and cloud-native workloads with built-in high-speed file transfer capabilities, cross-region offerings and integrated services. Use cases : Backup and recovery, Data archiving, Cloud-native application, AI and big data analytics.
