Cisco CCNP Enterprise 350-401 Questions & Answers

• Question 161:

  Refer to the exhibit.

  

  An engineer must configure an ERSPAN tunnel that mirrors traffic from Linux1 on Switch1 to Linux2 on Switch2. Which command must be added to the source configuration to enable the ERSPAN tunnel?

  A. (config-mon-erspan-src-dst)#no shut

  B. (config-mon-erspan-src-dst)#monitor session 1 activate

  C. (config-mon-erspan-src-dst)#traffic bidirectional

  D. (config-mon-erspan-src-dst)#ip address 10.10.10.10

  Correct Answer: D

  IP address in destination session and IP address in source session should match. If they don't- that is causing the drops. Reference: https://community.cisco.com/t5/networking-documents/understanding-span-rspan-and-erspan/ta-p/3144951

• Question 162:

  Refer to the exhibit.

  

  An engineer configured the Bonjour Gateway on a Cisco WLC to support Apple Airplay. Users cannot see Apple TV while on the WLAN. Which action resolves this issue?

  A. Disable Neighbor List Dual Band

  B. Enable mDNS Snooping

  C. Disable Directed Multicast

  D. Enable FlexConnect Local Switching

  Correct Answer: B

  To allow Bonjour to traverse the wireless network there will need to be some features enabled:

  +

  mDNS

  +

  Broadcast forwarding

  +

  Multicast

  +

  IGMP snooping

• Question 163:

  Refer to the exhibit. Reachability between servers in a network deployed with DHCPv6 is unstable. Which command must be removed from the configuration to make DHCPv6 function?

  

  A. ipv6 address 2001:0:1:4::1/64

  B. ipv6 dhcp server DHCPPOOL

  C. ipv6 nd ra suppress

  D. address prefix 2001:0:1:4::/64 lifetime infinite infinite

  Correct Answer: C

• Question 164:

  Refer to the exhibit. R6 should reach R1 via R5>R2>R1. Which action resolves the issue?

  

  A. Decrease the cost to 2 between R6-R5-R2.

  B. Decrease the cost to 41 between R2 and R1.

  C. Increase the cost to 61 between R2 and R3.

  D. Increase the cost to 61 between R2-R3-R1.

  Correct Answer: C

  The correct answer should be C.

  Answer B cannot be correct because in this case, traffic will be forwarded via R2-R3-R1 ( which has a total cost of 40 and is not the desired path) . R2-R1 has a total cost of 41 which is not lower than 40. Increasing the cost between R2 and

  R3 to 61 will be our best choice because the total cost via R2-R3-R1 will be 81 so this will not be the best path, making our desired path R2-R1 the best one ( with a cost of 80).

• Question 165:

  Refer to the exhibit. Router R2 should be learning the route for 10.123.187.0/24 via EIGRP. Which action resolves the issue without introducing more issues?

  

  A. Remove route redistribution in R2 for this route in OSPF.

  B. Use distribute-list to modify the route as an internal EIGRP route.

  C. Redistribute the route in EIGRP with metric, delay, and reliability.

  D. Use distribute-list to filter the external routes in OSPF.

  Correct Answer: A

• Question 166:

  Refer to the exhibit.

  

  What is the value of the variable list after the code is run?

  A. [1, 2], [1, 2], [1, 2]

  B. [1, 2] * 3

  C. [1, 2, 1, 2, 1, 2]

  D. [3, 6]

  Correct Answer: C

  >>> list = [1, 2] >>> list = list * 3 >>> print (list) [1, 2, 1, 2, 1, 2]

• Question 167:

  Which protocol is used to encrypt control plane traffic between SD-WAN controllers and SDWAN endpoints?

  A. DTLS

  B. IPsec

  C. PGP

  D. HTTPS

  Correct Answer: A

• Question 168:

  Which method is used by an AP to join HA controllers and is configured in NVRAM?

  A. stored WLC information

  B. DNS

  C. IP Helper Addresses

  D. Primary/Secondary/Tertiary/Backup

  Correct Answer: D

• Question 169:

  Refer to the exhibit. What is displayed when the code is run?

  

  A. The answer is 25

  B. The answer is 70

  C. The answer is 5

  D. The answer is 100

  Correct Answer: A

  The "magic" function receives a number, which is 5 from main() in this question. This function returns a result of 5 + 2*10 = 25 and the str() function converts it into a string ("25") before printing to the terminal.

  

• Question 170:

  Refer to the exhibit. An engineer implemented several configuration changes and receives the logging message on switch1. Which action should the engineer take to resolve this issue?

  

  A. Change the VTP domain to match on both switches

  B. Change Switch2 to switch port mode dynamic auto

  C. Change Switch1 to switch port mode dynamic auto

  D. Change Switch1 to switch port mode dynamic desirable

  Correct Answer: A
