• After a successful FLOGI, a host in a SaaS storage fabric receives a 24-bit Fibre Channel address. An engineer inspects the high 8 bits of that address. What do those bits identify?
• Two MDS switches in a SaaS company's new pod are linked by an ISL that isolates as soon as it comes up. Both switches are configured with the same static Fibre Channel domain ID. What change lets the fabrics merge?
• A SaaS storage admin adds a host and a target to a new zone, adds that zone to the zoneset, and the host still cannot see the target. The zoneset was not activated again after the edit. What is the missing step?
• A university engineer creates a device alias on one MDS switch and commits it there. A second MDS in the same fabric never shows the alias. CFS distribution for device alias is disabled. What is missing?
• A university storage engineer wants two ISLs between a pair of MDS switches to run as one SAN port-channel. One switch has the port-channel configured, and the peer still has two independent E ports. What is the right fix?
• A factory is choosing which MDS switch should be principal. One switch is set to priority 1 and the other is left at the default priority of 128. Which switch has the stronger bid?
• A factory IoT network host finishes FLOGI and receives a 24-bit Fibre Channel address. The HBA was not configured with a manual Fibre Channel address. Where does that address come from?
• A factory IoT network creates an fcalias in one VSAN and expects that same name to exist in a second VSAN on the same MDS. The second VSAN does not have the name. Which alias is fabric-wide rather than VSAN-local?
• A factory IoT network has a working zoneset in a VSAN. An engineer builds a second zoneset for a change window and activates it. Hosts that existed only in the first zoneset lose their targets. Why?
• A state university has a SAN port-channel configured on both MDS switches, and one member is already up in the channel. The second ISL stays out and is running at a different speed. What lets that member join?
• A state university enables device-alias distribution with CFS, enters a new alias, and the peer MDS still does not list it. The device-alias change was never committed. What is the missing step?
• A state university puts a host WWPN in a zone with an array, but the Fibre Channel name server on the MDS has no entry for that host. The host has not completed FLOGI. Why is the name server empty for it?
• A state university edge switch runs NPV toward a core MDS. The NPV connection is rejected, NPIV is disabled on the core, and the edge switch has no Fibre Channel domain ID. What should change on the core?
• A state university hypervisor reaches its datastore with iSCSI. An engineer edits a Fibre Channel zoneset, and the session still fails. The initiator has no HBA in this path. What identifies this host to the target?
• A factory IoT network carries two SAN applications on one MDS pair. A zoneset change for the sensor application must not disturb the controller application. What isolates those two fabrics?
• A factory IoT network brings up two MDS switches in a new VSAN, and both switches use the same domain-manager priority. Which switch becomes the principal switch?
• A state university storage engineer needs the actual Fibre Channel frames from one MDS port to inspect a malformed host sequence. Which tool collects those frames?
• A factory IoT network director has two supervisors, and both a system-image upgrade and an EPLD update are pending. The impact check reports the system image as nondisruptive. Which upgrade can keep Fibre Channel logins up?
• A factory IoT network host could see its target until an engineer activated a different zoneset in the same VSAN. The host's zone exists only in the previous zoneset. Why did access stop?
• A state university has a SAN port-channel configured on both MDS switches, yet one member stays out of the bundle while the other member is inside it. That member is hard-set to a different speed. What should change?
• A state university host is a member of the active zone with its target, yet the Fibre Channel name server has no entry for that host. What does the missing name-server entry mean?
• A state university enabled CFS distribution for device alias, edited an alias, and the peer MDS still shows the old database. The change is sitting in the pending copy and was never committed. What is the missing step?
• A factory IoT network engineer created an fcalias in one VSAN and cannot use that name when zoning a second VSAN on the same MDS pair. Which object is fabric-wide instead?
• A factory IoT network host is a member of the active zone, yet it has no Fibre Channel address and does not appear as logged in. When does the switch assign that 24-bit address?
• A state university host reaches its array by IP and an initiator IQN, but a new Fibre Channel zone does not make the LUN appear. Which control actually admits this iSCSI host?
• A factory IoT network has a sensor and a storage array logged into two different VSANs on the same MDS switch, and zoning inside each VSAN still does not let them communicate. Why are the two devices isolated?
• A state university set an edge MDS to NPV mode so the edge would not take a domain ID. The NP port comes up, but hosts behind the edge cannot log in through the core. NPIV is disabled on the core. What should be enabled, and where?
• A new MDS joins a factory IoT network fabric and is given a Fibre Channel domain ID. Which switch granted that domain ID?
• A state university storage engineer must see the actual Fibre Channel frames between a host and an array during a failed read. Which tool provides that frame copy?
• A factory IoT network MDS 9700 director has only one supervisor module installed. An engineer plans a system-image upgrade and expects forwarding to continue the whole time. Why will this upgrade interrupt the switch?
• A state university host completed FLOGI and now appears in the FCNS database, but it still cannot reach the array. An engineer treats the name-server entry as proof the zone allows the pair. What does that entry actually prove?
• A state university SAN port-channel is up with one member. A second ISL between the same MDS pair stays out because that link runs at a different speed. What lets the second link join?
• A state university MDS already has device-alias distribution enabled. An engineer adds an alias and the peer still shows the old database. The change was never committed. What is missing?
• A factory IoT network needs one friendly name for a controller port WWN in two VSANs, but an fcalias created in the first VSAN does not resolve in the second VSAN or on the peer switch. Which object supplies that shared name?
• A factory IoT network VSAN had a zoneset active that included the camera zone. An engineer activated a different zoneset that omits that zone, and the cameras lost the array. Why did the original zone stop working?
• A factory IoT network host is already in an active zone with its array, yet it has no Fibre Channel address because it has not completed FLOGI. When does the switch assign that 24-bit FCID?
• A state university runs an edge MDS in NPV mode so the edge does not take a domain ID, but the servers still cannot complete fabric login toward the core. NPIV is disabled on the core switch. What must change on the core?
• A factory IoT network will install a new system image on an MDS switch that has only one supervisor. The team wants forwarding to continue straight through the upgrade. What should they expect from this upgrade?
• A state university presents LUNs to hosts with iSCSI. An engineer adds a Fibre Channel zone that names those hosts and the array, and the hosts still cannot see the LUNs. What identifies an iSCSI host to that array?
• A factory IoT network trunks two VSANs across one TE port-channel. The first VSAN merges, and the second stays isolated because the trunk allows only the first VSAN. What lets the second VSAN use that same cable?
• A state university needs a copy of the Fibre Channel frames on one host port while that host attempts a process login to a target. Which MDS tool supplies that frame copy?
• A factory IoT network merged two MDS switches, and Fibre Channel domain IDs are being assigned by the switch the team did not want in charge. Which switch is allowed to assign those domain IDs?
• A factory IoT network host sits in the active zoneset, yet it has no Fibre Channel address and does not appear in the name server. The host has not completed fabric login. What assigns the 24-bit address?
• A factory IoT network converts an edge MDS to NPV mode so it will not take a Fibre Channel domain ID. Hosts behind that edge never complete FLOGI. NPIV is disabled on the core switch. What must change on the core?
• A state university has a SAN port-channel up between two MDS switches, but one member stays out of the channel. That member allows a different VSAN list than the channel, and both switches already have the channel configured. What should be corrected?
• A state university activates a second zoneset in a VSAN where a different zoneset was already active. Hosts that were members only of the first zoneset lose their targets. Why did the first zoneset stop enforcing?
• A state university creates an fcalias for a host in VSAN 10 and then references that same name from a zone in VSAN 20. The VSAN 20 zone will not resolve the name. Why?
• A factory IoT network shows a new host in the Fibre Channel name server after FLOGI, and an operator assumes the host can reach its target. The zoneset has no entry for that host. Which statement is correct?
• A factory IoT network cannot boot a host from an iSCSI LUN. The initiator IQN and the target portal IP were never configured. An administrator instead added the host to a Fibre Channel zoneset. What will actually let the host reach the LUN?
• A university VSAN has an active zoneset. Two devices that do not share any zone can still read and write to each other. The default-zone policy on the switches is permit. What is allowing that traffic?
• A university needs a copy of the Fibre Channel frames on one MDS port delivered to an analyzer. The SPAN session's destination is an existing ISL, and no frames arrive at the analyzer. What should the destination be?
• A factory connects a new MDS to a SAN whose device aliases run in basic mode. The new switch is in enhanced device-alias mode. The ISL comes up, but the device-alias databases never merge. Why?
• A factory MDS director has two supervisors. The install impact for the new system image reports that the upgrade is disruptive. What happens if the engineer continues with that image?
• A state university host logs in on VSAN 10. The target and the active zoneset that pairs them are in VSAN 20. Both VSANs exist on the same MDS. Why can the host not see the target?
• A media editor mounts a datastore with NFS. The storage admin adds the editor host bus adapter to a Fibre Channel zoneset and also requests an iSCSI IQN. The mount still succeeds or fails with the export. What actually admits this host?
• A factory MDS is already running a domain ID in VSAN 10. An engineer configures a different static domain ID for VSAN 10 only. Hosts keep their current FCIDs, and the running domain ID does not change. What applies the new static domain ID?
• A factory edge switch is supposed to attach as NPV. Its uplink to the core came up as an E port, and the edge requested its own domain ID. NPIV is already enabled on the core. What is the edge missing?
• A game studio hypervisor completes FLOGI on an MDS F port and receives one FCID. Virtual machines on that host send FDISC to request their own FCIDs, and the switch rejects those requests. NPIV is disabled. What does enabling NPIV allow on that port?
• A university host in VSAN 20 is zoned to an array on a second MDS, and that array is also in VSAN 20. The TE port-channel between the switches allows only VSAN 1. FSPF in VSAN 20 shows no path. What is missing?
• A university builds a Fibre Channel port-channel between two MDS switches. The engineer sets the member interfaces to LACP active mode, the same way the campus Ethernet port-channels are built. The SAN port-channel never comes up. Why?
