132A large enterprise data center has a disaster recovery site 100 km away. The SAN uses two MDS 9700 series switches at each site, connected via a dedicated dark fiber. Each link operates at 16 Gbps with a round-trip time of 2 ms. Recently, backup jobs to the remote storage array have been failing with timeout errors. The backup server is local to Site A, but the backup target is in Site B. The link utilization never exceeds 40%, and no errors are reported on the interfaces. The engineer suspects the issue is related to buffer credits. The current buffer credit count on the ISL is 16. The engineer calculates that for 16 Gbps over 100 km (2 ms RTT), they need at least 200 credits to maintain full throughput. Which action is most appropriate to resolve the issue?
133A small business SAN consists of a single Cisco MDS 9148S switch with 16 Gb Fibre Channel ports. The storage array has four active paths to the switch, and four servers each have two HBAs. The administrator wants to ensure that all paths are utilized and that no single point of failure exists. Currently, all devices are in a single VSAN and zoning is permissive (default deny). After powering on all devices, the administrator notices that the storage array only logs in on two of its four ports. The other two ports show 'no light'. The switch has not been configured with any port settings. What is the most likely cause?
134A company is deploying a new storage network using Cisco MDS 9700 switches. They have multiple host servers and storage arrays.

141Which TWO of the following are valid methods to configure zoning in a Cisco MDS 9000 series switch?
142A data center uses a Cisco MDS 9710 director with multiple line cards. The storage network includes several host servers connected to the director via 16 Gbps FC connections. Recently, the engineering team deployed a new storage array that supports 32 Gbps FC. To take advantage of the higher speed, they upgraded the host HBAs to 32 Gbps. However, after the upgrade, some hosts are experiencing intermittent connection drops. The team notices that when a host disconnects, it takes approximately 30 seconds to reconnect. The link lights on the host and switch ports are green. The switch logs show 'VSAN 100: Port fc1/1 is down (link failure)' messages. No other errors are reported. The MDS line cards support 32 Gbps, and the ports are configured with the 'speed 32000' command. What is the most likely cause of the intermittent drops?
143A large enterprise uses Cisco Nexus 5548UP switches in FCoE mode. The storage array is connected via native FC to an MDS 9700. The FCoE switches are connected to the MDS via FC uplinks. Recently, the storage team deployed a new FCoE initiator that requires access to a specific LUN. After configuring the zone and VSAN, the initiator cannot discover the target. The zone includes the pWWN of the target and the FCoE initiator's pWWN (derived from its MAC address). The initiator is in VSAN 100, and the target is in the same VSAN. The MDS show flogi database shows the initiator. The show fcoe database on the Nexus shows the initiator but the session is not active (state: FIP-VN_Port not logged in). The engineer checks the FIP snooping policy and notices that the FCoE VLAN to VSAN mapping is correct. What is the most likely issue?
144A small business has a Cisco MDS 9148S switch with a single fabric. Two hosts are connected to ports fc1/1 and fc1/2, and a storage array is connected to ports fc1/3 and fc1/4. The administrator wants to ensure that each host can only see its own assigned LUNs on the array. They have configured a zone for each host containing the host pWWN and the target pWWN for the respective LUNs. However, Host A is able to see Host B's LUNs. What is the most likely cause?
145An organization has four Cisco MDS 9700 directors connected in a full-mesh topology. They use VSANs to separate production, backup, and management traffic. The backup VSAN is experiencing high latency and occasional timeouts. The engineer runs the 'show fcspf routes' command and notices that the path from the backup host to the backup target has an uneven hop count across different paths. The links are all 16 Gbps. The engineer also notes that the backup target is connected to a different director than the backup host. Which action is most likely to improve performance?
146A large data center uses a Cisco Nexus 9000 switch with FCoE NPV feature. The switch is connected to an MDS 9700 upstream. The network team recently replaced the MDS 9700 with a new one. After the replacement, the FCoE hosts are unable to log in to the storage fabric. The Nexus switch shows that the FCoE NPV uplinks are up but no FLOGIs are being forwarded. The show npv flogi-table on the Nexus is empty. The upstream MDS shows that the uplinks are in VSAN 100, and the zoning is correct. The Nexus switch configuration includes 'feature npv' and 'npv enable' on the relevant interfaces. The FCoE VLAN 100 is mapped to VSAN 100. What is the most likely cause?
147A company is consolidating its storage network into a single fabric using a Cisco MDS 9509. They want to use VSANs to isolate different departments. The VSANs will be 10, 20, and 30. They have a single ISL between two MDS switches. The engineers want to carry all three VSANs over the ISL. They configure both ends of the ISL as E ports and enable trunking. After configuration, they notice that only VSAN 10 traffic passes over the ISL. The other VSANs appear isolated. The show vsan membership shows all three VSANs are present on both switches. The show interface trunk on the ISL shows that the trunk is up but only VSAN 10 is allowed. What is the most likely cause?
148A new storage administrator is configuring LUN masking on a Cisco MDS switch. The storage array presents two LUNs to the fabric with the same LUN ID (0) but to different target ports. The administrator wants to ensure that a specific host can access both LUNs. The host is connected to a single HBA port. The host will see both target ports in the same zone. After zoning, the host discovers both target ports but only sees the first LUN. The show flogi database shows the host's pWWN with two FC IDs assigned. What is the most likely issue?
149A storage administrator is troubleshooting a Fibre Channel SAN where initiators cannot log in to a target. The administrator verifies that the VSAN is configured correctly and that zoning is in place. Which two additional checks should be performed to resolve the issue?
150A storage administrator has been tasked with integrating a new Cisco MDS 9706 switch into an existing Fibre Channel SAN. The existing SAN consists of two Cisco MDS 9148S switches configured in a VSAN 100 with a single zone set that contains all initiator and target WWPNs. The administrator connects the new switch to one of the existing switches using an ISL and configures the new switch with VSAN 100 and the same zone configuration. The administrator activates the zone set on the new switch and verifies that the ISL is up and both switches see each other's Fibre Channel IDs. However, servers attached to the existing switches still cannot discover the storage targets that are connected to the new switch. The administrator has confirmed that the ISL is operational and that the zone set on the new switch is activated with the correct WWPNs. What should the administrator check next?
