1. Question 101 · 504 in bank

   Refer to the exhibit.

   

   What is the result of running the command presented?

   • AMulticast traffic forwarding is suspended.
   • BMRIB is flushed.
   • CThe PIM database is deleted.
   • DPIM join messages are suspended.

   Show answer

   Answer: C

   Explanation

   When you restart PIM, the following tasks are performed: ✑ The PIM database is deleted. ✑ The MRIB and MFIB are unaffected and forwarding of traffic continues. ✑ The multicast route ownership is verified through the MRIB. ✑ Periodic PIM join and prune messages from neighbors are used to repopulate the database.

   What is an advantage of NFSv4 over Fibre Channel Protocol?

   • Auses IP transport
   • Bcongestion management
   • Cimproved security
   • Dlossless throughput

   Show answer

   Answer: C

   Explanation

   Tricky one, NFS 4 has good authentication features, i dont see any kind of authentication on FC, most deployments are not in shared environments (in my experience) and if we talk about lossless traffic i would say FC is better positioned using reserved buffers for traffic than any solution over Ethernet. So I vote for C.

   A customer reports Fibre Channel login requests to a Cisco MDS 9000 Series Switch from an unauthorized source. The customer requires a feature that will allow all devices already logged in and learned to be added to the Fibre Channel active database. Which two features must be enabled to accomplish this goal? (Choose two.)

   • Aauto-learning
   • Bsmart aliases
   • Cport security
   • Denhanced zoning
   • Edevice aliases

   Show answer

   Answer: AC

   Explanation

   Port Security Activation By default, the port security feature is not activated in any switch in the Cisco MDS 9000 Family. By activating the port security feature, the following apply: Auto-learning is also automatically enabled, which means: From this point, auto-learning happens for the devices or interfaces that were already logged into the switch and also for the new devices will login in future. You cannot activate the database until you disable auto-learning. All the devices that are already logged in are learned and are added to the active database. All entries in the configured database are copied to the active database. After the database is activated, subsequent device login is subject to the activated port bound WWN pairs, excluding the auto-learned entries. You must disable auto-learning before the auto-learned entries become activated.

4. Question 104 · 504 in bank

   A network engineer must prevent data corruption due to cross fabric communication in an FCoE environment. Which configuration must be applied to the Cisco Nexus Unified Switches to achieve this objective?

   • Aswitch(config-if)# shutdown lan
   • Bswitch(config-if)# no fcoe fcf-priority 0
   • Cswitch(config)# fcoe fcmap 0e.fc.2a
   • Dswitch(config)# no fcoe fcf-priority 255

   Show answer

   Answer: C

   Explanation

   C You can prevent data corruption due to cross-fabric talk by configuring an FC-Map that identifies the Fibre Channel fabric for this switch. When the FC-Map is configured, the switch discards the MAC addresses that are not part of the current fabric. An FCF can assign Fabric Provide MAC Addresses (FPMA) to the CNAs consisting of the FC-Map Value for the Fabric and the Fibre Channel ID (FCID) assigned during Fabric Login switch# switchto vdc fcoe type storage fcoe# configure terminal fcoe(config)# fcoe fcmap 0x0efc2a

   Which NFS version uses the TCP protocol and needs only one IP port to run the service?

   • ANFSv1
   • BNFSv2
   • CNFSv3
   • DNFSv4

   Show answer

   Answer: D

   Explanation

   I believe its D, and "one ip port" i believe means one tcp port. From the cert guide: "the advantage of nfsv4 over its predecessors is that only one IP port, 2049 is used to run the service, which simplifies using the prticol across firewalls

6. Question 106 · 504 in bank

   

   Refer to the exhibit. A network engineer created a new role to be assigned to the SAN users. The requirement is for users to have these characteristics: * permitted to show access to the system, SNMP, module, and hardware information. * permitted to run debug zone and exec fcping commands. * restricted from accessing show feature environment command. Which configuration set meets these requirements?

   • AMDS-B(config)# role name default-role MDS-B(config-role)# rule 5 deny show feature environment
   • BMDS-B(config)# role name default-role MDS-B(config-role)# rule 5 permit show feature module MDS-B(config-role)# rule 6 deny *
   • CMDS-B(config)# role name san-users MDS-B(config-role)# rule 3 deny show feature environment
   • DMDS-B(config)# role name san-users MDS-B(config-role)# rule 3 permit show feature system MDS-B(config-role)# rule 4 permit show feature hardware MDS-B(config-role)# rule 5 permit show feature module

   Show answer

   Answer: A

   Explanation

   I think it's A because you can't deny what's already allowed on the default role. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/security/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_Security_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_Security_Configuration_Guide_7x_chapter_01000.pdf&ved=2ahUKEwjI3KD-6KD5AhWll1YBHXQpC9AQFnoECA4QAQ&usg=AOvVaw0LMfWmT-hIZrUAFuMORswG If you belong to multiple roles, you can execute a combination of all the commands permitted by these roles. Access to a commandtakes priority over being denied access to a command. For example, suppose a user has RoleA, which denied access to the configuration commands. However, the user also has RoleB, which has access to the configuration commands. In this case, the user has access to the configuration commands.

7. Question 107 · 504 in bank

   What is a characteristic of the NFS protocol?

   • AIt uses remote procedure calls with TCP/IP for transport.
   • BIt is used for booting Cisco UCS B-Series servers.
   • CIt is used to access a storage array at a block level.
   • DIt uses UDP and HTTP as its transport.

   Show answer

   Answer: A

   Explanation

   When a client wants to perform some type of action on a file on a particular machine, it uses RPC to make a call to the NFS server on that machine. The server accepts the request and performs the action required, then returns a result code and possibly data back to the client, depending on the request. The result code indicates if the action was successful. If it was, the client can assume that whatever it asked to be done was completed. For example, in the case of writing data, the client can assume the data has been successfully written to long-term storage. NFS can operate over any transport mechanism that has a valid RPC implementation at the session layer.

   A storage array must be connected to port ethernet1/10 on a Cisco MDS 9000 Series Switch. In addition, the array must connect using the FCoE protocol and be single-homed. Which configuration meets these requirements?

   • Avsan database vlan 101 vsan 101 fcoe vsan 101 interface vfc 10 interface 1/10 switchport mode e fcoe vfc 10
   • Binterface vfc 10 switchport mode f bind interface ethernet 1/10 vsan database vsan 101 vlan 101 fcoe vsan 101 vsan 101 interface vfc 10

   • Dvlan database vlan 101 fcoe vsan 101 enable interface vfc 10 vsan 101 interface vfc 10 switchport mode fcoe switchport access vlan 101 bind interface ethernet1/10

   Show answer

   Answer: B

   Explanation

   We must use mode f, because in a switch, on a port which connects to a node, we configure an F port (fabric port). On the endhost (array/storage) side, this port is an N (node) port.

9. Question 109 · 504 in bank

   What is the impact of an EPLD upgrade on a Cisco MDS 9000 Series Switch?

   • AThe standby supervisor module reloads multiple times.
   • BThe active supervisor traffic is disrupted.
   • CThe upgrade process disrupts only the module that is being upgraded.
   • DThe upgrade disrupts the management connectivity to the switch.

   Show answer

   Answer: C

   Explanation

   When you upgrade or downgrade the EPLDs, observe the following guidelines and limitations: ג€¢ You can upgrade each module only when it is online. The EPLD upgrade is only disruptive to the module being upgraded. ג€¢ If you interrupt an EPLD upgrade or downgrade, the module must be upgraded again. ג€¢ In Cisco MDS 9000 Director Switches, EPLD upgrade or downgrade can only be executed from the active supervisor module. To upgrade the supervisor EPLDs nondisruptively, upgrade the standby supervisor and then switchover. After the new standby supervisor is online its EPLDs can be upgraded. ג€¢ In Cisco MDS 9000 Series Fabric Switches, be sure to specify 1 as the module number. The switch must be power cycled for the EPLDs to start running the new code. Reference: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/8_x/release_notes/epld/epld_rn_8x.html
