Free Oracle 1Z0-1089-21 Exam Dumps Questions & Answers

You are building a filesystem of 10TB Storage Capacity with only one file server using "Balanced Elastic Performance tier" Oracle Cloud Infrastructure (OCI) Block Volume Storage. Balanced Elastic Performance tier throughtput scales at 480 KBPS/GB up to a maximum of 480 MBPS pervolume.
Which two options are correct about how many Block Volumes you can attach to the file server to get maximum IO throughput?

• A.  8 Block Volumes of 1.25TB size
• B.  20 Block Volumes of 500GB size
• C.  10 Block Volumes of 1TB size
• D.  One Block Volume of 10TB size

Which two Oracle Cloud Infrastructure (OCI) shapes are a good choice for Spark based workloads?

• A.  GPU
• B.  HPC
• C.  BM Standard
• D.  VM Standard

Oracle Cloud infrastructure (OCI) Block Volume Storage supportssharing a Block Volume among multiple compute Instances in read/write or read only shareable mode.
Which two file systems should be used to allow multiple compute Instances to read/write data concurrently without any data loss?

• A.  Parallel File Systems like Lustre, IBM Spectrum Scale(GPFS), BeeGFS, etc.
• B.  Network File System (NFS)
• C.  Distributed File Systemslike Gluster, OCFS2, GFS2
• D.  Linux File Systems like XFS, EXT4, EXT3, etc.

A file system is built using two BM.Standard2.52Compute shapes for File servers. On each file server, one 25 Gbps (3125 MB/s) NIC/network card is used to connect to 10 Block Volumes of 1TB each (max. 480MB/s per volume) and other 25 Gbps NIC Is used for sending/receiving data to/from client nodes.
Filesystem client instances which mount the file system are provisioned using VM.Standard2.16 Compute shapes. (Network bandwidth: l6.4Gbps(2050 MB/s)) What is the max aggregate IO throughput (theoretical) of the file system?

• A.  6250 MB/s
• B.  4800 MB/s
• C.  3125 MB/s
• D.  9600 MB/s

You have two different workloads, workload 1 does not scale very well (~100 cores) and requires a very high memory bandwidth, and a workload 2 that Is compute bound and IO intensive.
Which Instances shouldyou select?

• A.  1: BM.HPC2.36 2: BM.Standard.2.52
• B.  1: BM.Standard-2.52 2: BM.HPC2-36
• C.  1: BM.Standard.E3.128 2: BM.HPC2.36
• D.  1: BM.HPC2.36 2: BM.Standard.E3-128
