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. 
F. On N7K-2,decrease the HSRP priority to 50.

1.多項(xiàng)選擇題Overlay Transport Virtualization (OTV) overlay interface is a logical multiaccess and multicast- capable interface that must be explicitly defined by the user and where the entire OTV configuration is applied. Which statements are true about OTV overlay interface?()

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

3.多項(xiàng)選擇題A virtual port channel (vPC) allows links that are physically connected to two different Cisco Nexus devices to appear as a single port channel to a third device. Which are the mandatory steps for configuring vPC? ()   

A. Enable feature vPC
B. Define domains
C. Establish peer keepalive connectivity
D. Create a peer link
E. Configure the peer link as a trunk port
F. Create port channels and vPCs
G. Define port channel load-balancing method
H. Make sure configurations are consistent

5.多項(xiàng)選擇題The vPC 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? ()   

A. The vPC peer-gateway feature is enabled by default.
B. The vPC peer-gateway feature can be configured globally under the vPC domain submode.
C. 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.
D. The vPC peer-gateway feature only works with HSRP protocol.
