Sample Questions and Answers
What does the acronym FCIP stand for?
Fibre Channel Internal Protocol
B. Fibre Channel Internet Protocol
C. Fabric Channel Integrated Protocol
D. Fibre Channel Integrated Path
Answer: B. Fibre Channel Internet Protocol
Explanation:
FCIP enables the tunneling of Fibre Channel frames over IP networks, allowing long-distance SAN extension and connectivity between remote data centers using TCP/IP.
Which license is required for Cisco MDS advanced security features?
SAN Extension
B. Enterprise License
C. Enhanced Zoning License
D. Storage Services License
Answer: B. Enterprise License
Explanation:
The Cisco MDS Enterprise License enables advanced features such as fabric-wide QoS, SAN encryption, and advanced security policies like port security and traffic inspection.
What causes a zone merge failure in a fabric?
High latency
B. Duplicate FC-ID
C. Conflicting active zonesets
D. IVR configuration
Answer: C. Conflicting active zonesets
Explanation:
A zone merge failure occurs when two switches with different active zonesets attempt to merge fabrics. Consistency in active zonesets across switches is required for a successful merge.
What is the maximum number of VSANs supported on Cisco MDS 9700 Series?
64
B. 128
C. 256
D. 4096
Answer: D. 4096
Explanation:
Cisco MDS 9700 Series switches support up to 4096 VSANs, offering extensive scalability for large and multi-tenant environments. Each VSAN operates as an independent virtual fabric.
Which MDS feature allows centralized management and policy deployment?
VSAN
B. Cisco Fabric Manager
C. IVR
D. Smart Zoning
Answer: B. Cisco Fabric Manager
Explanation:
Cisco Fabric Manager is a centralized management application that provides GUI-based configuration, monitoring, and troubleshooting of SANs, including zoning, VSANs, and performance metrics.
What does the show topology command display on a Cisco MDS switch?
FCID assignments
B. FLOGI databases
C. SAN switch interconnections
D. Port speeds
Answer: C. SAN switch interconnections
Explanation:
The show topology command displays the logical layout of the SAN fabric, showing how switches and devices are interconnected. It is useful for visualizing the overall structure of the fabric.
Which protocol does Cisco MDS use for ISL routing?
EIGRP
B. OSPF
C. FSPF
D. RIPv2
Answer: C. FSPF
Explanation:
FSPF (Fabric Shortest Path First) is the default and only supported routing protocol for Fibre Channel fabrics. It determines the best path between switches based on link costs.
What is the result of enabling Smart Zoning?
Adds zones automatically
B. Reduces zoneset size
C. Disables WWN zoning
D. Limits VSAN count
Answer: B. Reduces zoneset size
Explanation:
Smart Zoning optimizes the zoning configuration by automatically reducing the number of zone entries. It allows initiators to communicate with all relevant targets without needing a separate zone for each pair.
Which command saves zoning changes to NVRAM?
copy run start
B. zoneset activate
C. zoneset save
D. write zoning
Answer: A. copy run start
Explanation:
After making zoning changes, use copy running-config startup-config to save them permanently. Otherwise, changes will be lost after a switch reload.
What port mode must be used to aggregate links into a port channel?
E-Port
B. F-Port
C. TE-Port
D. NP-Port
Answer: A. E-Port
Explanation:
Port channels on Cisco MDS switches require interfaces in E-Port mode. These ports connect switches and can be bundled into a single logical link for redundancy and higher throughput.
What component prevents duplicate domain IDs in a fabric?
IVR
B. Domain Manager
C. RSCN
D. Zoning
Answer: B. Domain Manager
Explanation:
The Domain Manager assigns and maintains unique domain IDs within a Fibre Channel fabric. If a switch attempts to join with a duplicate ID, it is isolated to prevent disruption.
How are devices grouped in a Fibre Channel zone?
By port speed
B. By WWN or port ID
C. By VLAN
D. By IP address
Answer: B. By WWN or port ID
Explanation:
Devices are grouped into zones using either their World Wide Names (WWNs) or the switch port identifiers they are connected to. This determines which devices can communicate within the fabric.
What command checks VSAN membership for a specific port?
show vsan member fc1/1
B. show interface fc1/1
C. show vsan usage
D. display port vsan
Answer: B. show interface fc1/1
Explanation:
The show interface command displays information about the physical and logical settings of a port, including its assigned VSAN. It’s useful for verifying proper configuration.
What is the role of a principal switch in a Fibre Channel fabric?
Assign FCIDs
B. Route IVR traffic
C. Control domain ID assignment
D. Handle zoning
Answer: C. Control domain ID assignment
Explanation:
The principal switch in a fabric coordinates domain ID distribution and ensures unique IDs for each switch. It plays a key role during fabric formation and domain merges.
What happens when IVR NAT is enabled?
Enables address translation between VSANs
B. Activates IP routing
C. Assigns dynamic FCIDs
D. Allows trunking
Answer: A. Enables address translation between VSANs
Explanation:
IVR NAT (Network Address Translation) allows initiators and targets in different VSANs to communicate without exposing their real FCIDs. It provides security and address masking.
How does the default-zone permit command affect traffic?
Blocks unknown traffic
B. Allows all unzoned devices to communicate
C. Enables port mirroring
D. Limits device login
Answer: B. Allows all unzoned devices to communicate
Explanation:
By setting the default zone behavior to permit, all devices not explicitly zoned are allowed to communicate. This is generally not recommended in production due to security concerns.
What command shows the current firmware version on a Cisco MDS switch?
show version
B. show firmware
C. show image
D. display version
Answer: A. show version
Explanation:
The show version command displays software and firmware version details, hardware model, uptime, and other system-level information. It’s often the first step in audits and troubleshooting.aa
