  1. Question 1Intermediate

    Deployment · Secure Boot

    A storage administrator is preparing to deploy a new Cisco MDS 9700 Series Switch. The security policy mandates that the switch must validate the authenticity of the hardware anchor and the software microloader before loading the operating system. Which technology provides this capability to prevent counterfeit hardware and software tampering?

    Show answer & explanation

    Correct answer: C

    Cisco Secure Boot is the technology that ensures the integrity of the device by validating the hardware anchor (a tamper-resistant chip) and the microloader before the BIOS or OS loads. This establishes a chain of trust from the hardware up to the OS.

  2. Question 2Beginner

    Deployment · Installation and Initial Setup

    You are configuring PowerOn Auto Provisioning (POAP) for a large-scale MDS deployment. The switches are in a dedicated management network. Which DHCP option must be configured on the DHCP server to provide the Python script path to the booting MDS switches?

    Show answer & explanation

    Correct answer: A

    While Option 150 is common for TFTP IPs, POAP specifically looks for the script name. The bootfile name is provided via Option 67 (Bootfile Name) in standard DHCP/BOOTP operations, which POAP utilizes to identify the script to download.

  3. Question 3Intermediate

    Deployment · Initial Configuration

    During the initial setup of a Cisco MDS 9000 switch using the setup utility, you are prompted to enable the 'fc-admin' account. What is the primary function of this specific account in the MDS architecture?

    Show answer & explanation

    Correct answer: A

    The fc-admin account (or role) is designed for VSAN-based administration, allowing a user to manage specific VSANs without having full 'admin' or 'network-admin' privileges over the entire chassis.

  4. Question 4IntermediateSelect 2

    Implementation · NPV and NPIV

    An architect is designing an N-Port Virtualization (NPV) solution using Cisco MDS 9000 Series switches. Which TWO statements accurately describe the requirements and behavior of NPV mode? (Select TWO)

    Show answer & explanation

    Correct answers: C, E

    For the NPV switch to log in multiple end devices through the same uplink, the core switch must support and have NPIV enabled to assign multiple FCIDs on a single port.

    Enabling NPV mode (feature npv) is a disruptive action that reboots the switch and purges the current configuration to convert it from switching mode to NPV mode.

  5. Question 5Advanced

    Implementation · Inter-VSAN Routing

    You are implementing Inter-VSAN Routing (IVR) to share a tape library in VSAN 10 with servers in VSAN 20. You have configured the IVR topology and zoneset. However, the servers cannot see the tape library. The show ivr zone command shows the zone as 'active' but the members are not logged in. What is the most likely cause?

    Show answer & explanation

    Correct answer: C

    For IVR to work, the end devices must effectively be logged into the fabric. If they are not zoned in their local VSAN (or if the IVR zone isn't effectively merging visibility), they won't communicate. However, the critical requirement often missed is that IVR zones function independently, but the underlying physical connectivity and FLOGI must be stable.

  6. Question 6Intermediate

    Implementation · Fibre Channel Port Channels

    Which command sequence correctly configures a Fibre Channel interface to use the source and destination ID for load balancing across a port channel?

    Show answer & explanation

    Correct answer: B

    The command port-channel load-balance src-dst-id sets the load balancing algorithm to use both Source and Destination FCIDs. This is a global configuration or per-VSAN configuration, not typically per-interface, but it affects the interfaces in the channel.

  7. Question 7Intermediate

    Implementation · Device Aliases and Zoning

    True or False: In a Cisco MDS environment, Smart Zoning reduces the size of the Access Control List (ACL) TCAM usage by only creating entries for devices that are actually logged into the fabric, rather than all members of the zone.

    Show answer & explanation

    Correct answer: B

    False. Smart Zoning reduces ACL TCAM usage by only programming entries for 'initiator-to-target' pairs. It eliminates the unnecessary 'initiator-to-initiator' and 'target-to-target' entries that standard zoning creates. The login status is less relevant than the member type (initiator/target/both).

  8. Question 8Intermediate

    Implementation · FCoE Implementation

    A customer is implementing FCoE on a Cisco Nexus 7000 core connected to an MDS 9700. They need to map the Fibre Channel traffic from VSAN 20 to a specific VLAN on the Ethernet network. Which configuration step accomplishes this mapping?

    Show answer & explanation

    Correct answer: A

    The correct method is to enter the VLAN configuration mode for the dedicated FCoE VLAN and map it to the VSAN using fcoe vsan .
