SAN Design at Scale CCIE Quiz

1. In FC SAN design, what is the purpose of a persistent binding?

Prevents fabric remerging

Ensures consistent LUN mapping across fabric changes

Blocks unauthorized port access permanently

Disables VSAN traffic during maintenance

2. In enterprise SAN deployments, what role does the Fabric Login Service play?

Authenticates administrators only

Assigns domain IDs and manages fabric member discovery

Encrypts all FC traffic automatically

Monitors switch CPU temperature

3. Which SAN best practice helps prevent fabric loop formation during switch additions?

Disabling all ISL ports initially

Using Spanning Tree Protocol in the fabric

Implementing proper domain assignment and merge policies

Removing all zoning configurations

4. What is the primary purpose of a SAN core-edge design in large environments?

Reduce operational costs by minimizing switch count

Provide scalability, performance, and simplified management

Eliminate the need for ISL configuration

Enforce stricter security policies automatically

5. In SAN design, what does the term 'oversubscription' refer to?

Assigning more VSANs than physical switches

Configuring more users than storage capacity

Connecting more devices to ports than bandwidth supports

Creating redundant zoning rules

6. Which Fibre Channel fabric port type is used exclusively for fabric-to-fabric connections?

E_Port

F_Port

N_Port

L_Port

7. What is the primary benefit of implementing SAN traffic segmentation via VSANs?

Increases total fabric bandwidth

Isolates workloads and improves security and performance

Eliminates the need for storage arrays

Reduces switch hardware requirements

8. In a multi-tier SAN architecture, what distinguishes the edge tier from the core tier?

Edge connects hosts; core provides fabric interconnection

Core connects hosts; edge provides backup functions

Both tiers perform identical functions

Edge tier is optional in large deployments

9. Which metric is critical for measuring SAN fabric performance at scale?

Switch CPU utilization only

Frame loss rate, latency, and throughput

Number of VSANs configured

Total port count on all switches

10. What does N_Port ID Virtualization (NPIV) enable in a SAN?

Multiple virtual hosts to share a single HBA port

Reduction of switch port count by 50%

Automatic fabric failover without manual intervention

Encryption of all FC frames

11. What is the primary advantage of implementing VSANs in a Fibre Channel fabric?

Reduces latency between storage arrays

Isolates traffic and enables multi-tenancy within a single physical fabric

Increases FC port bandwidth automatically

Eliminates the need for zoning policies

12. Which SAN topology provides the best redundancy for critical data center environments?

Single-switch fabric

Full-mesh multi-switch fabric

Linear daisy-chain topology

Star topology with single core

13. What is Inter-Switch Link (ISL) bandwidth typically reserved for in large fabrics?

Only storage replication traffic

Fabric control frames and inter-switch communication

Backup and disaster recovery exclusively

Host-to-storage traffic only

14. Which protocol is used for SAN fabric management and monitoring in Cisco systems?

SNMP

SSH

Fibre Channel Management Service (FCMS)

HTTP

15. In SAN design, what does QoS (Quality of Service) primarily control?

Switch port speed negotiation

Bandwidth allocation and traffic prioritization

VSAN membership assignment

Fabric login timeout values

16. What role does the Principal Switch play in a SAN fabric?

Manages VSAN creation and deletion only

Performs domain assignment and fabric merge negotiations

Blocks all interswitch links automatically

Restricts zoning configuration to administrators

17. Which Fibre Channel speed is most commonly deployed in modern data centers?

4 Gbps

8 Gbps

16 Gbps

32 Gbps

18. What is the maximum hop count in a Fibre Channel fabric?

5 hops

7 hops

10 hops

15 hops

19. In a SAN fabric, what does the F_Port connect?

Fabric to fabric

Node to switch port

Switch to switch

Storage to backup device

20. Which zoning method is most secure for large-scale SAN deployments?

Port zoning

WWN-based zoning

Domain zoning

Alias zoning
