Q163. Dynamic ARP inspection ensures that only valid ARP requests and responses are relayed. Which three activities does a Cisco NX-OS device perform when DAI is enabled and properly configured? (Choose three.)

A. Verifies that each of these intercepted packets has a valid IP -to-MAC address binding based only on DHCP snooping binding database.

B. Verifies that each of these intercepted packets has a valid IP -to-MAC address binding based only on DHCP snooping binding database or statically created entries.

C. Intercepts ARP request and responses on all ports.

D. Pass-through an invalid ARP packets.

E. Drops invalid ARP packets.

F. Intercepts ARP request and responses only on untrusted ports.

Answer: B,E,F

Q164. Which statement is true about The QoS Class Fibre Channel?

A. Cannot be disabled

B. Cannot have the QoS changed

C. Can have "Packet Drop" enabled

D. Is multicast optimized?

E. Can have the MTU changed

Answer: A

Q165. Refer to the exhibit.

Given the displays from N5K-1 and N5K-2, what is the expected result if the zone mode enhanced vsan 1 command is issued on N5K-1?

A. The mode change will complete with a warning that the zone database from N5K-1 will be distributed throughout the fabric.

B. The mode change will not complete due to the mismatch in the default zone mode.

C. The mode change prompts the administrator to override the default zone mismatch and make them the same.

D. The mode change completes, and the default zone setting remains unchanged in N5K-1 and N5K-2.

E. The default zone setting is set to deny in both switches because it is more secure.

Answer: A

Q166. In one-armed design, which method must be used to achieve symmetric load balancing in ACE?

A. Dual NAT

B. Round Robin

C. Dynamic Routing Protocol

D. MAC Probe

Answer: A

Q167. Which three statements about OTV are true? (Choose three.)

A. An internal interface is a Layer 2 interface on the edge device that connects to the VLANs that are to be extended. These VLANs typically form a Layer 2 domain known as a site and can contain site-based switches or site-based routers. The internal interface is a Layer 2 access or trunk interface regardless of whether the internal interface connects to a switch or a router.

B. An external interface is a Layer 2 interface on the edge device that connects to the VLANs that are to be extended. These VLANs typically form a Layer 2 domain known as a site and can contain site-based switches or site-based routers. The external interface is a Layer 2 access or trunk interface regardless of whether the external interface connects to a switch or a router.

C. An overlay interface is a logical multiaccess multicast-capable interface. The overlay interface encapsulates Layer 2 frames in IP unicast or multicast headers.

D. An overlay interface is a logical multiaccess multicast-capable interface. The overlay interface encapsulates Layer 3 frames in IP unicast or multicast headers.

E. The join interface is one of the uplink interfaces of the edge device. The join interface is a point-to-point routed interface. The edge device joins an overlay network through this interface. The IP address of this interface is used to advertise reachability of a MAC address that is present in this site.

F. The join interface is one of the uplink interfaces of the edge device. The join interface is a point-to-point routed interface. The edge device joins an overlay VLAN through this interface. The IP address of this interface is used to advertise reachability of a MAC address that is present in this VLAN.

Answer: A,C,E

A. MR

B. ESS

C. ELP

D. EFP

E. none of the above

Answer: C
