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

  1. NFSv1
  2. NFSv2
  3. NFSv3
  4. NFSv4

Answer(s): D

Explanation:

One big advantage of NFSv4 over its predecessors is that only one UDP or TCP port, 2049, is used to run the service, which simplifies using the protocol across firewalls.

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?

  1. MDS-B(config)# role name default-role MDS-B(config-role)# rule 5 deny show feature environment
  2. MDS-B(config)# role name default-role MDS-B(config-role)# rule 5 permit show feature module MDS-B(config-role)# rule 6 deny *
  3. MDS-B(config)# role name san-users MDS-B(config-role)# rule 3 deny show feature environment
  4. MDS-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

Answer(s): A

What is a characteristic of the NFS protocol?

  1. It uses remote procedure calls with TCP/IP for transport.
  2. It is used for booting Cisco UCS B-Series servers.
  3. It is used to access a storage array at a block level.
  4. It uses UDP and HTTP as its transport.

Answer(s): 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?

  1. vsan database vlan 101 vsan 101 fcoe vsan 101 interface vfc 10 interface 1/10 switchport mode e fcoe vfc 10
  2. interface vfc 10 switchport mode f bind interface ethernet 1/10 vsan database vsan 101 vlan 101 fcoe vsan 101 vsan 101 interface vfc 10
  3. vlan database vlan 101 vsan vsan 101 fcoe vsan 101 interface vfc 10 interface ethernet1/10 switchport mode trunk bind interface vfc 10 fcoe vsan 101
  4. vlan 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

Answer(s): 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.
