FEC Technical Demonstration: https://www.youtube.com/watch?v=tu0jiyf-jnk Brocade YouTube: https://www.youtube.com/user/brocadevideo?feature=watch 2) With all necessary licenses installed, which two types of trunking are used in the non-routed fabric shown in the exhibit? (Choose two.) A) F_Port B) EX_Port C) ISL D) ICL ISL trunking is being used between the two DCX s, and F_Port trunking is being used by the host with the Brocade adapter connected to the Access Gateway. There is no routing, so EX_Ports are not is use, and there are no ICL cables between the two DCX s. 3) You are implementing F_Port trunking in your fabric. What are two requirements for your implementation? (Choose two.) A) It can be implemented with a Brocade adapter. B) It can be implemented with an Access Gateway. C) You can configure only two F_Ports in one trunk group. D) You can configure only four F_Ports in one trunk group. You can trunk between a Brocade adapter and a switch that is in native mode only. You cannot trunk between a Brocade adapter and an Access Gateway. For information on F_Port trunking for Brocade Adapters and F_Port trunking in Access Gateway refer to the Fabric OS Administrator s Guide and the Access Gateway Administrator s Guide. 4) Which license is required to enable all UltraScale Inter-Chassis Links between two Brocade Backbones? A) ICL 8-link B) ICL 16-link C) ICL 1st POD D) ICL 2nd POD C is the only correct option. For information on available licenses please refer to the Fabric OS v 7.2 Release Notes and the Fabric OS Administrator s Guide for v7.2. Section 2 5) You must have Fibre Channel connectivity in the top of every rack. You also need to limit the number of domain IDs in the fabric. Which Brocade technology will satisfy this requirement? A) Access Gateway B) Virtual Fabrics C) FC-FC Routing D) Administrative Domains Access Gateway allows you to configure a switch to be logically transparent to a fabric enabling you to connect more devices without consuming domain IDs. See the Access Gateway Administrator s Guide for more information. 6) You need to prevent the addition of a new switch to the fabric as shown in the exhibit. What will achieve this? A) Create an SCC policy with DID2 and DID4; save the SCC policy. B) Create an FCS policy with DID2 and DID4; save the FCS policy. C) Create an SCC policy with DID2 and DID4; activate the SCC policy. D) Create an FCS policy with DID2 and DID4; activate the FCS policy. Only the Switch Connection Control policy will allow you to control which switches may join the fabric, and it must be activated across all switches in the fabric. 7) You notice that some N_Ports on a Brocade 6510 in Access Gateway mode are heavily used while others are not. You want to balance the utilization. Which feature enhances performance for the N_Ports? A) Preferred N_Port B) F_Port Trunking C) E_Port Trunking D) Port Grouping F_Port Trunking helps enhance performance of N_Ports on an Access Gateway. Grouping the ports does nothing, E_Port trunking does not apply since Access Gateway does not use E_Ports to connect to a fabric. 8) Which two statements about Access Gateway mode are true? (Choose two.) A) It can connect NPIV-enabled HBAs. B) It can aggregate multiple hosts to a connected F_Port uplink to a core fabric. C) It can aggregate multiple targets to a connected F_Port uplink to a core fabric. D) It can aggregate multiple hosts onto a single N_Port uplink to a core fabric. Access Gateway uses N_Ports to connect to F_Ports in the fabric. 9) Which three devices are supported by a switch in Access Gateway mode? (Choose three.) A) FICON channel B) FCP initiators C) FCP targets D) iscsi initiators E) fabric switches FICON traffic is not supported in Access Gateway and iscsi is used to transport SCSI over the IP protocol. 10) You are moving some FC ports on your Brocade DCX 8510 from one logical switch to another switch and notice a failure error. What are two reasons for this happening? (Choose two.) A) QoS is enabled on the ports. B) F_Port buffers are enabled on the ports. C) They are configured as E_Ports. D) They are configured as EX_Ports. EX_Ports can be moved out of a base switch because the port is disabled when it is moved; you will not, however, be able to enable it in a non-base switch until you remove the EX_Port configuration. E_Ports are supported in all logical switch types. Section 3 11) You are configuring a new user in Brocade Network Advisor. You must assign a custom Area of Responsibility for this user. Which two objects can be defined? (Choose two.) A) Fibre Channel switch B) host C) target D) fabric The Area of Responsibility determines what devices a Network Advisor user can see in their interface. Additional permissions can be configured to specify what actions can be performed on those devices. spirit110:fid128:admin portstatsshow 16 stat_wtx byte words transmitted stat_wrx byte words received stat_ftx Frames transmitted stat_frx Frames received stat_c2_frx 0 Class 2 frames received stat_c3_frx Class 3 frames received stat_lc_rx 0 Link control frames received stat_mc_rx 0 Multicast frames received stat_mc_to 0 Multicast timeouts stat_mc_tx 0 Multicast frames transmitted tim_rdy_pri 0 Time R_RDY high priority tim_txcrd_z Time TX Credit Zero (2.5Us ticks) tim_txcrd_z_vc 0-3: tim_txcrd_z_vc 4-7: tim_txcrd_z_vc 8-11: tim_txcrd_z_vc 12-15: er_enc_in 0 Encoding errors inside of frames er_crc 0 Frames with CRC errors er_trunc 0 Frames shorter than minimum er_toolong 0 Frames longer than maximum er_bad_eof 0 Frames with bad end-of-frame er_enc_out 0 Encoding error outside of frames er_bad_os 0 Invalid ordered set er_rx_c3_timeout 0 Class 3 receive frames discarded due to timeout er_tx_c3_timeout 0 Class 3 transmit frames discarded due to timeout er_c3_dest_unreach 0 Class 3 frames discarded due to destination unreachable er_other_discard 0 Other discards er_type1_miss 0 frames with FTB type 1 miss er_type2_miss 0 frames with FTB type 2 miss er_type6_miss 0 frames with FTB type 6 miss er_zone_miss 0 frames with hard zoning miss er_lun_zone_miss 0 frames with LUN zoning miss er_crc_good_eof 0 Crc error with good eof er_inv_arb 0 Invalid ARB open 0 loop_open transfer 0 loop_transfer opened 0 FL_Port opened starve_stop 0 tenancies stopped due to starvation fl_tenancy 0 number of times FL has the tenancy nl_tenancy 0 number of times NL has the tenancy zero_tenancy 0 zero tenancy 12) Several users have complained that they are having performance issues accessing databases. Referring to the output shown in the exhibit, which statement is true regarding this storage port? A) The port has a congestion bottleneck. B) Host multipathing is not in use. C) The port is using the wrong fill word type. D) The SFP in this port is malfunctioning. The bottleneck can be seen by looking at the tim_txcrd_z counters. You can see that the bottleneck is occurring on VC 4 and could be impacting traffic. Keep in mind that a certain amount of txcrd_z events are to be expected, however, a large number of events in a short period of time can be a sign of a congestion bottleneck, especially on long distance links. Section 4 13) You want to implement Traffic Isolation (TI) zones in your Gen 5 fabric. Which statement is true? A) The TI zones modify the route table. B) The TI zones modify the link cost for traffic on the path. C) The TI zones set the QoS traffic for the path. D) The TI zones can force low-priority traffic on to a given ISL. Configuring TI zones does not modify the route table or link cost of any connections. TI zones do not affect QoS, which is a separate configuration. Only option D applies. 14) You are creating a custom Monitoring and Alerting Policy Suite (MAPS) policy using a default policy as a template with different thresholds for the rules. Which three actions are required to accomplish this? (Choose three.) A) Create a clone of the default policy you want to modify. B) Create clones of the default rules you want to modify. C) Modify the default rules in the cloned policy with the new thresholds. D) Disable the active policy prior to enabling the new one. E) Remove the default rules from the new policy. Default rules and policies cannot be modified. They must be cloned and then the changes made to the cloned rule or policy. See the Monitoring and Alerting Policy Suite Administrator s Guide for more information. 15) You are configuring Flow Vision on a Brocade 6520 with Fabric OS v7.2. Which three statistics generated by flow monitors will be supported? (Choose three.) A) the number of frames received by the flow destination B) the number of SCSI I/O bytes read as recorded for the flow C) the number of megabytes (MB) transmitted per second by the flow source D) the number of exchanges received per flow destination E) the number of average buffer credits per flow source or destination Only A, B & C are supported by flow monitors. See the Flow Vision Administrator s Guide for more information. 16) You have deployed Top Talkers in your fabric. You have chosen to use Fabric mode. Which two statements are true? (Choose two.) A) Top Talker monitors are installed on all F_Ports in the fabric. B) Top Talker monitors are installed on all E_Ports in the fabric. C) End-to-End monitors must be removed from the switches. D) End-to-End monitors must be installed on the switches. When fabric mode is enabled, you can no longer install Top Talker monitors on an F_Port unless you disable fabric mode. Section 5 17) You have a Brocade DCX with the Virtual Fabrics feature enabled. You want to enable FC-FC routing with this chassis as the backbone. Which statement is true regarding this environment? A) EX_Ports must be configured on the default logical switch in the chassis to connect edge fabrics. B) Device sharing from the backbone fabric to the edge fabrics is supported. C) A base switch must be created with the routing ports assigned to it. D) The backbone fabric can be expanded to other logical switches in interopmode. In Virtual Fabrics all EX_Ports must be in the base logical switch; they are not supported in any other switch type. Additionally base logical switches only support E/EX and VE/VEX port types. Device ports cannot be attached to a base logical switch. 18) Referring to the exhibit, you need to deploy FC-FC routing across an FCIP link to isolate your two routed fabrics. Which port configuration will complete the configuration? A) Port A= EX_Port; Port B = E_Port; Port C= E_Port; Port D = E_Port B) Port A= E_Port; Port B = VE_Port; Port C= VE_Port; Port D = E_Port C) Port A= EX_Port; Port B = VE_Port; Port C= VEX_Port; Port D = EX_Port D) Port A= E_Port; Port B = VE_Port; Port C= VEX_Port; Port D = E_Port D is the only answer that meets the requirements of deploying an FC-FC routing configuration across the FCIP link. A and B do not meet the requirements. Answer C is not a valid configuration because it would create a cascaded routing environment which is not supported. 19) You have multiple FC routers connected to the same edge fabric. You need to reduce the resources used in an FC router by limiting the number of LSAN zones. What would you do to accomplish this task? A) Use target proxies. B) Use the enforce tag. C) Use QoS. D) Use the speed tag. The enforce tag is used to specify which LSAN zones a FC router will import. Section 6 20) You have deployed Brocade FX8-24 blades. You have decided to set up several FCIP links between the data centers. Which three port configurations are available for simultaneous use on each blade? (Choose three.) A) two 10 Gbps ports and ten 1 Gbps ports B) one 10 Gbps port and ten 1 Gbps ports C) ten 1 Gbps ports D) two 10 Gbps ports and two 1 Gbps ports E) two 10 Gbps ports These are the only supported options. 21) Referring to the exhibit, on which two ports can you configure bottleneck detection? (Choose two.) A) Port 1 B) Port 2 C) Port 3 D) Port 4 Bottleneck detection is supported on E/EX ports and F/FL ports. 22) You will be configuring a long distance FC link between two sites located 50 km apart. The link will be used for a combination of data replication and server backups. You also want to ensure that Forward Error Correction (FEC) can be used on the link. Which two configurations will meet this requirement? (Choose two.) A) Configure the port in L0 mode. B) Configure the port in LS mode. C) Configure the port in LD mode. D) Configure the port in LE mode. L0 and LE mode do not support the distance required. The only options are using LS and LD mode. FEC is supported in all long distance modes. Section 7 23) You observed that one of your Brocade DCX s experienced a failover. You logged into the switch and ran errshow to determine why the failover occurred, but nothing besides the failover message was displayed. What is the reason no other messages are shown? A) You needed to use the -a option to display all messages. B) The output of this command is unique for each control processor. C) You needed to run the -r option to obtain a revised output. D) The output of this command is unique for each core blade. Brocade DCX/DCX-4S and DCX / backbones keep a separate RASLog for each CP. 24) Host H1 is unable to communicate with the target T5. Referring to the exhibit, how can this be resolved? A) Change the FIDs value to match on H1's and T5's fabrics. B) Use Node WWNs for LSAN zones for H1 and T5. C) Connect an ISL between FID 4 and FID 5. D) Connect an IFL between FID 1 and FID 5. Cascaded routing configurations are not supported. For host H1 to see the target T5, FIDs 4 and 5 need to be joined into a single backbone fabric. You can then setup backbone-edge routing between H1 and T5. 25) You have physically connected a new server HBA to the switch and cannot see your storage in a multiswitch fabric. Which method would be used to identify the fault, and have the least impact on the fabric? A) Disconnect, and then reconnect the storage so that it logs back into the fabric. Verify the LUN masking on the storage device. Verify the storage vendor driver for support. B) Remove one of the ISLs between the switches and reconnect. Remove the other ISLs one at a time; add a new ISL. Change the Domain ID of the switch where the new HBA was installed. C) Reboot the switch where the HBA was just installed. Reboot the server; reboot the storage sub-system. D) Verify the LED on the connected port. Verify the status of the port using switchshow. Verify for security blocking; verify the entry in nsshow for device membership. Verify zoning entries for new device. Option D is the best option because it has the least impact to the rest of the fabric. Disconnecting the storage will interrupt access from other devices, as will disconnecting the ISLs. Rebooting a switch, server, or storage device can also be disruptive.
