Exam Coverage Areas
1. Networking — Fibre Channel, Ethernet, zoning, WWNs, FSPF, ECMP, multipathing, iSCSI, VLANs, MTU, and
network performance.
2. Virtualization and Containers — bare metal, hypervisors, oversubscription, containers, and orchestration.
3. Storage Protocols and Architectures — FC, iSCSI, NVMe-oF, SAN, NAS, DAS, block/file/object storage.
4. Storage Media and Protection — HDD, flash, RAM, RAID, erasure coding, scale-up, scale-out, active-
active, and active-passive.
5. Cloud Storage — public, private, hybrid cloud and block, file, and object storage.
6. Replication and Disaster Recovery — synchronous, asynchronous, near-synchronous replication, RPO,
RTO, fault domains, and DR planning.
7. Backup and Snapshots — incremental/differential backups, snapshots, application consistency, and crash
consistency.
8. Storage Security — authentication, authorization, accountability, encryption, least privilege, and
ransomware protection.
9. Hosts and Servers — MPIO, host operating systems, HA, blade/rack/tower servers, NFS, and SMB.
10. Enterprise Storage Design — availability, performance, scalability, redundancy, workload requirements,
and operational trade-offs.
1. Which characteristic makes Fibre Channel particularly appropriate for
enterprise storage environments requiring predictable, reliable
connectivity?
A. It depends entirely on wireless networking
B. It is designed specifically for storage networking with controlled, reliable
transport
C. It eliminates the need for storage controllers
D. It only supports file-level storage
Answer: B
,Rationale: Fibre Channel is purpose-built for storage networking and is
commonly used where predictable performance, reliability, and dedicated
storage connectivity are important.
2. A storage administrator is designing a highly available SAN environment
using Fibre Channel switches and redundant host connections. Which
design is most appropriate?
A. One host adapter connected to one switch
B. Multiple independent paths between hosts and storage
C. One Ethernet cable shared by every host
D. A single Fibre Channel port connected through an unmanaged hub
Answer: B
Rationale: Multiple independent paths provide redundancy and allow
storage connectivity to continue if a component or path fails.
3. What is the primary purpose of zoning within a Fibre Channel storage
area network environment?
A. Increasing the physical capacity of SSDs
B. Defining which initiators can communicate with particular targets
C. Converting block storage into object storage
D. Compressing Fibre Channel frames
Answer: B
Rationale: FC zoning controls communication relationships within the fabric,
helping restrict and organize initiator-to-target connectivity.
,4. Which identifier is commonly associated with uniquely identifying Fibre
Channel devices within a storage networking environment?
A. WWN
B. VLAN ID
C. IP subnet mask
D. MAC broadcast address
Answer: A
Rationale: World Wide Names, or WWNs, are unique identifiers used by
Fibre Channel devices and are important when configuring SAN connectivity
and zoning.
5. A company wants dedicated storage networking with predictable
latency for critical database workloads. Which technology would
traditionally be an appropriate choice?
A. Fibre Channel
B. Consumer Wi-Fi
C. Bluetooth
D. Public DNS
Answer: A
Rationale: Fibre Channel is widely used for enterprise SAN workloads
requiring reliable, predictable storage connectivity.
6. Which statement best distinguishes Fibre Channel from ordinary
Ethernet networking in an enterprise storage environment?
, A. Fibre Channel cannot carry storage traffic
B. Ethernet can only provide wireless connectivity
C. Fibre Channel was specifically designed around storage networking
requirements
D. Ethernet cannot support high bandwidth
Answer: C
Rationale: Ethernet is a general-purpose networking technology, while Fibre
Channel was designed specifically for high-performance storage networking.
7. What is the primary function of a Fibre Channel fabric in a SAN
environment?
A. Provide routing and switching between Fibre Channel-connected devices
B. Convert RAM into flash memory
C. Store application databases permanently
D. Replace the host operating system
Answer: A
Rationale: A Fibre Channel fabric provides the switching infrastructure
through which initiators and storage targets communicate.
8. Which Fibre Channel switch type is generally designed to provide high
port density and scalability for large enterprise SAN environments?
A. Director-class switch
B. Consumer Ethernet hub
C. Wireless access point
D. Desktop bridge
