Understand ACI Fabric: ACI fabric policies are applied to manage and control the network traffic within the fabric1.
Identify Policy Application: Policies in ACI are applied between Endpoint Groups (EPGs), which are collections of network endpoints with common policy requirements1.
Recognize Policy Direction: These policies can be applied in a unidirectional or bidirectional manner, providing flexibility in controlling the flow of traffic between EPGs1.
Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with Cisco’s guidelines on ACI fabric policies, which state that policies can be applied between two or more EPGs and can be either unidirectional or bidirectional1.
Question 2
You are expanding a PowerMax 8000. What is the maximum allowed dispersion, in meters, between bricks?
Options:
A.
30
B.
25
C.
20
D.
35
Answer:
C
Explanation:
Review PowerMax 8000 Specifications: The PowerMax 8000 is designed to support a dispersed configuration, allowing for flexibility in the physical placement of its components1.
Identify Maximum Dispersion: The maximum allowed dispersion between bricks in a PowerMax 8000 system is up to 25 meters1.
Understand Dispersion Considerations: This dispersion allows for the separation of individual or contiguous groups of system bays, providing options for physical layout within a data center1.
Reference Official Documentation: The Official Dell VxBlock Deploy Achievement document would align with this specification, ensuring that the system meets both performance and physical space requirements1.
Question 3
Which data layout technique is used on an Isilon cluster?
Options:
A.
Parity Correction Error (PCR)
B.
Backward Correction Error (BCR)
C.
Error Correction Code (ECC)
D.
Forward Correction Error (FEC)
Answer:
D
Explanation:
The data layout technique used on an Isilon cluster is Forward Correction Error (FEC). This method ensures data integrity and availability by distributing error correction information across the nodes in the cluster, allowing for data recovery in the event of hardware failures.
