Correct Answer: C
Overlay Transport Virtualization (OTV) uses the Authoritative Edge Device (AED) to perform which tasks?
A. The AED is responsible for sending all unicast traffic in a site, while either node in a site can transmit multicast and broadcast.
B. The AED is responsible for load balancing all traffic for all VLANs across the transport network.
C. The AED is responsible for handling all unicast, broadcast, and multicast traffic for a given VLAN within a site.
D. The AED is responsible for MAC address dispute contention for a given VLAN.
Correct Answer: C
Which three statements about the DHCP snooping feature on Cisco Nexus switches are true?
A. DHCP snooping commands are not available until the feature is enabled with the feature dhcp snooping command.
B. When you enable the DHCP snooping feature, the switch begins building and maintaining the DHCP snooping binding database.
C. The switch will not validate DHCP messages received or use the DHCP snooping binding database to validate subsequent requests from untrusted hosts until DHCP snooping is enabled globally and for each specific VLAN.
D. Globally disabling DHCP snooping removes all DHCP snooping configuration on the switch.
E. Globally disabling DHCP snooping does not remove any DHCP snooping configuration or the configuration of other features that are dependent upon the DHCP snooping feature.
Correct Answer: BCE
Which three statements describe user authentication in Cisco DCNM-LAN? (Choose three.)
A. Cisco DCNM-LAN server users are local to the Cisco DCNM-LAN server. Creating, changing, and removing Cisco DCNM-LAN server users has no effect on user accounts on managed devices.
B. A Cisco DCNM-LAN server user that has Administrator privileges can push out changes to managed devices even if the Cisco NX-OS role that is used on the discovered device has the network operator role.
C. Cisco DCNM-LAN user roles restrict the ability of users to make changes to Cisco DCNM-LAN server settings. Cisco NX-OS user roles enforce read/write privileges on the discovered devices.
D. Cisco DCNM-LAN allows you to configure unique credentials for each discovered device or use default credentials when you do not configure unique credentials for a device.
E. Cisco DCNM-LAN can use AAA servers to authenticate users. Only TACACS servers are supported.
Correct Answer: ACD
Nexus# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Nexus(config)# interface Loopback10
% Permission denied
no Negate a command or set its defaults
username Configure user information.
end Go to exec mode
exit Exit from command interpreter
What is the reason why this user is not able to enter configuration commands?
A. The user did not enter enable prior to going into configuration mode.
B. The software license installed on Nexus is Layer 2 only, which does not allow the creation of Layer 3 interfaces.
C. The user RBAC role is set to network-operator.
D. The user failed authentication and user access defaulted to read-only mode.
E. The AAA server is currently not responding.
Correct Answer: C
Which three statements describe the configuration change management feature in DCNM LAN?
A. Switch profiles allow configurations to be synchronized between switches and are supported with any Cisco NX-OS Software managed device.
B. DCNM LAN can archive configurations from devices even if they are not managed by the DCNM server, and the administrator can supply the device management IP address and credentials.
C. You can archive a maximum of 50 configuration versions per managed device.
D. Managed devices must be licensed in DCNM LAN before they can be used with configuration change management.
E. Device-running configuration will be archived only if it differs from the last archived version.
Correct Answer: CDE
Which three statements best describe HSRP configuration on Cisco Nexus switches? (Choose three.)
A. In a vPC topology, the primary HSRP router will respond to ARP requests, but both HSRP routers will forward data traffic. No additional configuration is required.
B. In a vPC topology, the primary HSRP router will respond to ARP requests, but both HSRP routers will forward data traffic if the peer-gateway feature is enabled.
C. You can configure two overlapping HSRP groups to load share traffic from the connected hosts while providing the default router redundancy.
D. You can use the show standby command to verify HSRP operation and configuration.
E. If you remove the feature hsrp command, all relevant HSRP configuration information is also removed.
Correct Answer: ACE
Which statement describes SNMP functionality in Cisco NX-OS Software?
A. NX-OS Software supports one instance of SNMP globally for all VDCs; however, MIB counters are collected and reported individually per VDC.
B. SNMP must be enabled with the feature snmp command before any SNMP configuration is possible.
C. SNMP is always enabled by default in NX-OS Software and cannot be disabled.
D. NX-OS Software supports 3DES and AES for SNMPv3 message encryption.
E. SNMP always uses the default VRF on the Cisco Nexus 7000 Series Switches.
Correct Answer: D
Which statement describes the graceful restart capability in Cisco NX-OS Software?
A. In NX-OS Software, the OSPFv2 graceful restart extension is Cisco proprietary and is only compatible with other Cisco routers.
B. A graceful restart allows OSPFv2 to remain in the data forwarding path through a process restart. When OSPFv2 needs to restart, it first sends a type 8 LSA, which includes a grace period that tells NSF helpers to keep all LSAs that originated from the restarting interface.
C. Graceful restart helps keep an NX-OS system forwarding traffic transparently even if it experiences a cold reboot.
D. If the restarting OSPFv2 interface does not come back up before the end of the grace period, or if the network experiences a topology change, the OSPFv2 neighbors tear down adjacency with the restarting OSPFv2 interface and treat it as a normal OSPFv2 restart.
E. OSPFv3 graceful restart must be disabled before doing an ISSU.
