administrator has installed an N7K-F248-25XP module into
an existing chassis. The module is powered on, but the
interfaces are all in VDC0. What is the reason for this?
The chassis needs an EPLD upgrade to support the new

overrides any misconfiguration.
You can manually configure channel groups, or they can
be automatically created.
Changes in configuration to the SAN port channel
interface must also be made to all members of the

statement about Cisco Unified Fabric switches is
The Nexus 5000 family of switches does not support vPC
when running in either NPV or FCoE NPV mode.
The MDS 9100 family of switches is an excellent design
choice as a Unified Fabric edge switch.
The Nexus 7000 Series Switches can support the NPIV mode
of operation, but cannot function as a complete Fibre
The Nexus 7000 Series Switches cannot support advanced
Cisco Fibre Channel features such as IVR.
The MDS family of Cisco Unified Fabric switches supports
both the Fibre Channel Forwarder and Fibre Channel
statement about SAN port channels configured on Cisco
Nexus 5000 Series Switches is true?
single SAN port channel can have both Fibre Channel and
virtual Fibre Channel interfaces.
SAN port channels can include up to 16 interfaces.
SAN port channels distribute traffic across all links in
the port channel when source ID and destination ID load
balancing are used.
The links in SAN port channels can be connected to
different sets of switches.
The On mode of operation means ports only operate as
part of a SAN port channel or remain inactive.
capabilities are not supported in DCNM device manager?
manage SNMPv3 security access to switches
save and copy configuration files and software images
configure VLANs and Ethernet port channels
manage 2148T FEX, 2232PP FEX, and 2248TP FEX
What is the
use of NPV in Cisco Unified Computing Systems? (Choose
Compatibility with third-party Fibre Channel switches
Reduce domain IDs in a Fibre Channel environment
Support for increased number of VSANs
Support for SAN port channels
default VDC is configured to limit resources to a
specific module type, what happens when a module that
does not match the resource type is installed?
The module is powered up, and interfaces are in an
"admin down" state.
The module is denied power, and a syslog message is
The module is powered up, and interfaces are allocated
The module is powered up, and interfaces are allocated
What is the
mechanism that is used to allocate MAC addresses that
are assigned to the VDC for the system MAC address?
uses a random MAC address from the IEEE OUI block that
is assigned to Cisco.
The VDC system MAC is pulled from the active supervisor
and concatenated through a hash to ensure uniqueness.
uses a value that is based on a range that is assigned
to the SPROM of the system backplane.
The VDC system MAC is based on a range that is allocated
to the first line card that is installed in the switch.
flow-control port states lead to enabled link flow
control? (Choose three.)
Receive port: Enabled, Transmit port: Enabled
Receive port: Enabled, Transmit port: Desired
Receive port: Enabled, Transmit port: Disabled
Receive port: Disabled, Transmit port: Desired
Receive port: Desired, Transmit port: Desired
configuration with redundant supervisors, how many IP
addresses are required to configure full remote access
via management 0?
Two IP addresses, one for each supervisor
Three IP addresses, one virtual IP and one physical IP
for each supervisor
One IP address that is shared among supervisors
Noneómanagement 0 will use the IP address from the first
SVI that is created
configuration using DCNM can be completed by which two
supported methods? (Choose two.)
Copy and paste the VLAN, along with its VLAN ID, name,
type, admin state, and admin status, from one device to
Create a single VLAN or a range of VLANs.
VLAN is created only after choosing File > Deploy to
After a VLAN is created, it requires the state to be
Modify the existing VLAN by choosing Interface > VLAN >
jumbo frame support on a Cisco Nexus 5500 Switch can be
done through which method?
Changing the default policy map from a default MTU of
1500 to 9216
Using the command system jumbomtu 9216
Using the command interface MTU 9216
Configuring the default Ethernet system class to an MTU
of 9216 with a new network QoS policy map
statements about authentication settings for DCNM-LAN
are true? (Choose two.)
none of the authentication servers that are configured
for the current authentication mode responds to an
authentication request, the DCNM-LAN server falls back
to local authentication.
DCNM-LAN only supports TACACS+.
Each DCNM-LAN server will have the same device
Administering DCNM-LAN authentication settings requires

required for proper implementation of jumbo frame
support on a Cisco Nexus 2000 Series Fabric Extender?
The interface configured as FEX fabric requires the MTU
to be set to jumbo.

peer-gateway capability allows a vPC switch to act as
the active gateway for packets that are addressed to the
router MAC address of the vPC peer. This feature enables
local forwarding of such packets without the need to
cross the vPC peer link. Which statements are true about
the vPC peer-gateway? (Choose two.)
The vPC peer-gateway feature is enabled by default.
The vPC peer-gateway feature can be configured globally
under the vPC domain submode.
Enabling the peer-gateway feature automatically disables
IP redirects on all interface VLANs mapped over a vPC
VLAN to avoid generation of IP redirect messages for
packets switched through the peer gateway router.
The vPC peer-gateway feature only works with HSRP
