Oracle 1Z0-1089-21 Real Exam Questions Test Engine Dumps Training With 56 Questions [Q30-Q49]

QUESTION 30
Which two options are valid when configuring health check policies in Oracle Cloud Infrastructure (OCI) Load Balancing?

QUESTION 31
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?

QUESTION 32
Whichis an accurate analogy for Amdahl’s law?

QUESTION 33
A two node clustered/parallel filesystem built using Baremetal Compute shape (BM.Standard2.52) and Block Volume Storage delivers maximum sustained aggregate IO throughput of 5GB/s for read and write, while storing a single copy of the data (replica=l) in filesystem.
What will be the maximum sustained aggregate IO throughput for read and write, when two copies of the data (replica=2) are stored in filesystem for High Availability?

QUESTION 34
You are running a cluster using multiple BM.Standard2.52 machines. Themodel is on a NFS share running on block volume- You’ve tried doubling the number of machines but It’s not running any faster.
Which two actions could potentially speed up this tightly coupled workload?

QUESTION 35
What HDFS replication factor can be used with Block Volumes to optimize cost?

QUESTION 36
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?

QUESTION 37
For customers who want to copy HDFS data from their on-premise Hadoop cluster to Oracle Cloud Infrastructure (OCI),which three are Oracle supported methods?

QUESTION 38
Which Statement Is NOT correct?

QUESTION 39
You are building a file system that needs to handle large files with a lot of nodes reading at the same time.
What minimum size of block volume maximizes throughput for large files?

QUESTION 40
A customer has a very busy workload. The model is very large (1 PB range) and only some small files are updated for new jobs. Throughput needed during the run is roughly 25GB/s.
What Is a fast and cost-conscious way to handle the file system?

QUESTION 41
When an instance pool scales in, what is the correct order that the instances are terminated?

QUESTION 42
You are comparing different processors for Monte-Carlo simula-tion with millions of single core executions.
What frequency will have the highest impact on the “time to solution” ?

QUESTION 43
You are building a filesystem to maximize throughput of large files using high performance block volume and BM.Standard2.52 as file server.
Which block volume configuration should you choose to ensure aggregate Block volume throughput is higher than network bandwidth of a file server?

QUESTION 44
On Oracle Cloud Infrastructure (OCI), a customer wants to build a3TB filesystem for high IOPS workloads (like relational databases, small files, etc).
Which action provides the highest IOPS using OCI block volumes for storage?

QUESTION 45
What HDFS replication factor should be used for locally attached storage In HDFS?

QUESTION 46
Which statement explains how instances are distributed in an instance pool?

QUESTION 47
What minimum size of block volume with Balanced performance tier maximizes throughput for large files?

QUESTION 48
Which two performance metrics can be used to trigger scaling actions In Autoscaling?

QUESTION 49
Compute nodes are on subnet2(l72.16.1.0/24) and there is a BM.Dense.I02.8 on subnet1.
(1 /2.16.0.0/24) that will serve as a bastion, file server and license server. The bastion will be accessed through a public IP with SSH.
Which security lists should you choose for an HPC cluster? Ifmultiple options are possible, choose the one limiting access the most.
