- A. Configure pause error-disable recovery
- B. Enable link level pause on the interface
- C. Reset priority flow counters
- D. Set priority flow control pause
Answer:
a
Question 2

- A. Modify the VLAN assignment to vNICs.
- B. Change the PIN groups on the vHBAs.
- C. Modify the FCoE VLAN.
- D. Set the FCoE VLAN as the native VLAN on server uplinks.
Answer:
a
Question 3
Refer to the exhibit. An engineer deploys a SAN environment with two interconnected Cisco MDS 9000 Series Switches. When the engineer attempts a zone merge, it fails with the error that is presented in the exhibit. Which action resolves the issue?
- A. Import or export a zone set between the switches to synchronize the switches.
- B. Change the name of one of the zones to match the other zone set.
- C. Ensure that the zone members have different names.
- D. Set the distribute policy of the zone to full.
Answer:
c
Question 4
A vPC Type-1 inconsistency between two vPC peers in a VXLAN EVPN setup is discovered. Which two actions need to be attempted to resolve the issue?
(Choose two.)
- A. Configure the NVE interfaces to be Up on both switches.
- B. Set a different distributed gateway virtual MAC address.
- C. Set a different secondary IP addresses on NVE source-interface.
- D. Configure the same VNI to multicast group maping.

Question 5
Refer to the exhibit. Sw1 and Sw2 are two Cisco Nexus 9000 Series Switches that run Cisco NX-OS. They are VTEPs in the same vPC domain. What occurs in this scenario?
- A. Sw1 drops all traffic because there is no (S, G) OIF list to encapsulate VXLAN multicast packets and send them out to the underlay network through the uplink interfaces.
- B. Sw1 performs the VXLAN multicast encapsulation and decapsulation for all traffic associated with the VXLAN VNIs.
- C. Sw1 and Sw2 perform the VXLAN multicast encapsulation and decapsulation for all traffic associated with the VXLAN VNIs, depending on the hashing.
- D. Sw2 does not send an IP PIM register to the rendezvous point for the multicast group of the VXLAN VNI.
Answer:
b
Question 6
A customer configures HSRP between two data centers that are interconnected with OTV. The configuration succeeds, but traffic between two ESXi virtual hosts on the same site is routed suboptimally through the OTV overlay. Which two actions optimize the traffic? (Choose two.)
- A. Disable first-hop redundancy.
- B. Filter HSRP traffic by using a Layer 3 VACL on the OTV edge devices.
- C. Filter HSRP by using a Layer 2 MAC list on the ESXi vSwitch.
- D. Filter HSRP traffic by using a Layer 3 VACL on the ESXi vSwitch.
- E. Filter HSRP by using a Layer 2 MAC list on the OTV edge devices.

Question 7
Refer to the exhibit. An engineer fails to install Perl in the guest shell on a Cisco Nexus 9000 Series Switch. Which two actions must be taken in the guest shell to resolve the issue? (Choose two.)
- A. Add the DNS server and suffix.
- B. Add a default gateway and nameserver.
- C. Install the unbound resolver package using curl.
- D. Configure domain-name and nameserver under the management VRF.
- E. Export the http_proxy and https_proxy environment variables.

Question 8
Refer to the exhibit. When an engineer inserts 8-Gb Fibre Channel SFP port 15 on a Cisco UCS Fabric Interconnect, the port fails. What is causing this issue?
- A. Port 15 is configured as an Ethernet port.
- B. Port 15 is configured for 4-Gb Fibre Channel.
- C. Port 15 is missing a license.
- D. The polarity of the fiber cable is reversed.
Answer:
b
Question 9
Refer to the exhibit. An engineer is troubleshooting the connectivity between Server-1 and Server-2. Which action resolves the connectivity issue?
- A. Enable BGP advertise pip feature on both leaf switches
- B. Configure the same source IP address on NVE and virtual peer link on leaf switches
- C. Classify CFS messages for strict priority queue on spine switches
- D. Change all ports on spine switches as port-type fabric
Answer:
a
Question 10
Refer to the exhibit. A network engineer is configuring the FCoE N_Port virtualization storage area network. After the initial implementation, server 11 fails to connect to the disk array. Which action resolves the issue?
- A. On MDS interface vfc 1/1, change switchport mode configuration to VF
- B. On N9K interface vfc11, change switchport mode configuration to NP
- C. On N9K interface vfc11 and MDS interface vfc 1/1, change switchport mode configuration to F
- D. On N9K interface vfc11 and MDS interface vfc 1/1, change switchport mode configuration to E
