Question 3

Refer to the exhibit.

You install a new Cisco Nexus F3-Senes module on a Nexus 7700 Series
switch. When you attempt to allocate an interface from the module to a new VDC, an error occurs. Which issue could cause the error?

A. The limit-resource vlan minimum 16 maximum 4054 command is missing

B. The limit-resource module-type f3 command is missing

C. Cisco Nexus F3-Series modules are unsupported in VDCs

D. Cisco Nexus F3-Senes modules are unsupported on Nexus 7700 Series Switches

Correct Answer: B

Question 4

A leaf is programmed with the correct VLANs and interfaces, but the servers in web EPG are unreachable from the outside Layer 2 network. You use a unique external L2out EPG as a Layer 2 extension inside the Cisco ACI fabric. Which action do you take to resolve the communication issue?

A. Configure an MTU of 9000 bytes on the devices in the L2out EPG

B. Bind the web EPG to a port/leaf

C. Configure contracts between the web EPG and the L2out EPG.

D. Enable a spanning tree on the VLANs on the leaf.

Correct Answer: C

Question 5

Which two effects of enabling the persistent FC ID fealure are true? (Choose two)

A. N Ports receive the same FC IDs when they disconnect from and reconnect to any port on the same switch

B. The contents of the volatile cache are discarded wtien a server reboots

C. The fcdomain automatically adds entries to the FC ID database when a device connects to a port

D. The volatile cache stores up to 4,000 entries containing the WWN to FC ID binding. New entries overwrite the oldest entries in the cache if the cache is full

E. The FC IDs used in the fcdomain are saved after you reboot the switch

Correct Answer: C,E

Question 6

Refer to the exhibit. The two switches are stuck in the EXCHANGE and EXSTART states. Which issue could cause the problem?

A. The subnet mask is mismatched

B. The interfaces are not connected

C. The IP address of the OSPF process is incorrect

D. The MTU is mismatched

Correct Answer: D

Question 7

Refer to the exhibit.

You have two Cisco Nexus 9000 Series Switches named SwitchA and SwitchB.
SwitchA resides in Area 49.0001. SwitchB resides in Area 49.0002 and connects to the Ethernet
2/1 interface on SwitchA. The configuration of SwitchA is shown in the exhibit. SwitchA cannot see IS-IS routing updates from SwitchB. What is a possible cause of the issue?

A. The is-type configuration in router configuration mode and the isis circuit-type configuration on the interface are misconfigured on SwitchA.

B. Area 49.0002 is not configured on SwitchA

C. The IS-IS NSAP address is missing on the Ethernet 2/1 interface of SwitchA

D. The neighbor statement defining SwitchB is missing on the Ethernet 2/1 interface of SwitchA

Correct Answer: B

Question 8

You are using the Cisco ACI programmatic features and you receive this error message from the REST API:
Token was invalid (Error. Token timeout)
Which option is a possible cause of the error?

A. The header or request sent to the web server is malformed such that the request cannot be parsed by the web server
