It allows partial zone set changes to be distributed without having to activate a zone set.
What is the grace period in a graceful restart situation?
how long NSF-aware neighbors should wait after a graceful restart has started before tearing down adjacencies
Which of the following Cisco Nexus features is best managed with DCNM-LAN?
Which two statements about implementing Cisco NPV and NPIV on a Cisco Nexus 5000 Series switch are true? (Choose two.)
All VLANs must be in the same mode, CE, or FP.
These require an enhanced Layer 2 license to run.
Which SCSI terminology is used to describe source and destination nodes?
initiators and targets
Which two types of traffic are carried over a vPC peer link when no failure scenarios are present? (Choose two.)
multicast data traffic
broadcast data traffic
Which FCoE component is responsible for the encapsulation and de-encapsulation of Fibre Channel frames in Ethernet?
FCoE logical endpoint
Which two issues explain why a packet is not being routed as desired in a policy-based routing configuration? (Choose two.)
The next hop that is configured in the route map is not in the global routing table.
The next hop that is configured in the route map has a higher metric than the default next hop.
Which statement about RADIUS configuration distribution using Cisco Fabric Services on a Cisco Nexus 7000 Series Switch is true?
Cisco Fabric Services does not distribute the RADIUS server group configuration or server and global keys.
Which item represents the process that allows FCoE multihop using T11 standard FC-BB-5?
How does an FCoE end node acquire its FCoE MAC address?
fabric-provided MAC address
Which statement about the Layer 3 card on the Cisco Nexus 5500 Series Switch is true?
Up to 16 FEX connections are supported.
Which statement is true if password-strength checking is enabled?
Short, easy-to-decipher passwords will be rejected.
Which two items are services that are provided by Cisco Fabric Services? (Choose two.)
device alias distribution
DPVM configuration distribution
When local RBAC user account has the same name as a remote use account on an AAA server, what happens when a user with name logs into a merged (logical OR) a Cisco Nexus switch?
Only the roles that are defined on both accounts are merged (logical AND).
Which option is a restriction of the unified ports on the Cisco UCS 6200 Series Fabric Interconnect when connecting to the unified fabric network?
10-G Fibre Channel ports only use SFP+ interfaces.
Which GLBP load-balancing algorithm ensures that a client is always mapped to the same VMAC address?
Which command enables NPIV on Cisco Nexus 5000 Series Switches and Cisco MDS switches?
switch(config)# feature npiv
Which two statements about Cisco Nexus 7000 line cards are true? (Choose two.)
M1, M2, and F1 cards are allowed in the same VDC.
M line cards support Layer 2, Layer 3, and Layer 4 with large forwarding tables and a rich feature set.
Which statement about RBAC user roles on a Cisco Nexus switch is true?
Access to a command takes priority over being denied access to a command.
The connectivity Management Processor monitors the active supervisor module on Cisco Nexus 7000 switch and will reboot the device in the event of a light-out management issue. However, which option includes features that provide similar benefits in the absence of the Connectivity Management Processor?
In policy-based routing, which action is taken for packets that do not match any of the route-map statements?
forwarded using destination-based routing
Which Cisco Nexus feature is best managed with DCNM-SAN?
After enabling strong, reversible 128-bit Advanced Encryption Standard password type-6 encryption on a Cisco Nexus 7000, which command would convert existing plain or weakly encrypted passwords to type-6 encrypted passwords?
switch# encryption re-encrypt obfuscated
Which command sequence correctly enables Adapter FEX on Nexus 5000 Series Switches?
switch(config)# install feature-set virtualization switch(config)# feature-set virtualization
Which policy-map action performs congestion avoidance?
On a Cisco Nexus 7000 Series router, which statement about HSRP and VRRP is true?
The VRRP group IP address can be the same as the router-specific IP address.
Which protocol is responsible for the discovery of FCoE capabilities on a remote switch?
The Connectivity Management Processor monitors the active supervisor module on a Cisco Nexus 7000 switch and will reboot the device in the event of a lights-out management issue. However, which option includes features that provide similar benefits in the absence of the Connectivity Management Processor?
high-availability functionality from features such as vPC and NSF
Which statement about scalability in Cisco OTV is true?
The control plane avoids flooding by exchanging MAC reachability.
In the dynamic vNIC creation wizard, why are choices for Protection important?
They select the primary fabric association for dynamic vNICs.
A Cisco Nexus 2000 Series Fabric Extender is connected to two Cisco Nexus 5000 Series switches via a vPC link. After both Cisco Nexus 5000 Series switches lose power, only one switch is able to power back up. At this time, the Cisco Nexus 2000 Series Fabric Extender is not active and the vPC ports are unavailable to the network. Which action will get the Cisco Nexus 2000 Series Fabric Extender active when only one Cisco Nexus 5000 Series switch is up and active?
Configure reload restore or auto-recovery reload-delay on the Cisco Nexus 5000 Series switch that is powered on.
Which two items are feature that are available in VN-Link in software? (Choose two.)
Which statement about electronic programmable logic device image upgrades is true?
You can execute an upgrade or downgrade only from the active supervisor module.
Which two items are features that are available in VN-Link in software? (Choose two.)
