Cisco NX-OS Software supports SNMPv1， SNMPv2c， and SNMPv3. Both SNMPv1 and SNMPv2c use a community-based form of security. SNMPv3 provides secure access to devices by a combination of authenticating and encrypting frames over the network. Which security features are provided in Cisco NX-OS SNMPv3？ （）
A. encryption—scrambles the packet contents to prevent them from being seen by unauthorized sources
B. password—a password （community string） sent in clear text between a manager and agent for added protection
C. authentication—determines that the message is from a valid source
D. message integrity—ensures that a packet has not been tampered with while it was in transit
E. user—to determine if user authentication is used instead of community strings

The network administrator is seeing N7K-1 having issues with VLAN 11， and interface VLAN 11 is resetting， causing frequent HSRP state changes. Which two actions would reduce HSRP state changes？ （）
A..On N7K-1，configure the HSRP extended hold timer to 180， extending the HSRP hello message hold time.
B..On N7K-2，configure the HSRP extended hold timer to 180， extending the HSRP hello message hold time.
C..On N7K-1，configure the pre-empt delay minimum to 180 in order to delay N7K-1 from taking over as the HSRP active router.
D..On N7K-2，configure the pre-empt delay minimum to 180 in order to delay N7K-2 from taking over as the HSRP active router.
E..On N7K-2，increase the HSRP priority to 150.

A. When an OTV edge device receives a Layer 2 frame destined for a remote data center site， the frame is logically forwarded to the overlay interface.
B. The OTV edge device performs the dynamic OTV encapsulation on the Layer 2 packet and sends it to the join interface toward the routed domain.
