  A. local buffer overload

  B. err-disabled port on the far end

  C. physical errors

  D. duplicate IP addressing

  Correct Answer: C

• Question 1352:

  What is the functionality of the Cisco DNA Center?

  A. IP address pool distribution scheduler

  B. data center network policy controller

  C. console server that permits secure access to all network devices

  D. software-defined controller for automation of devices and services

  Correct Answer: D

• Question 1353:

  What provides connection redundancy increased bandwidth and load sharing between a wireless LAN controller and a Layer 2 switch?

  A. VLAN trunking

  B. tunneling

  C. first hop redundancy

  D. link aggregation

  Correct Answer: D

• Question 1354:

  How does MAC learning function on a switch?

  A. broadcasts frames to all ports without queueing

  B. adds unknown source MAC addresses to the address table

  C. sends a retransmission request when a new frame is received

  D. sends frames with unknown destinations to a multicast group

  Correct Answer: B

  when a switch recieves PDUs it examins the mac address to see if its already in its table and if its not it then adds it to its own table this process is called mac address learning

• Question 1355:

  Refer to the exhibit.

  

  Which configuration establishes a Layer 2 LACP EtherChannel when applied to both switches?

  A. Interface range G1/1 - 1/3 switchport mode trunk channel-group 1 mode active no shutdown

  B. Interface range G1/1 - 1/3 switchport mode access channel-group 1 mode passive no shutdown

  C. Interface range G1/1 - 1/3 switchport mode trunk channel-group 1 mode desirable no shutdown

  D. Interface range G1/1 - 1/3 switchport mode access channel-group 1 mode on no shutdown

  Correct Answer: A

  LACP uses active and passive

• Question 1356:

  Refer to the exhibit. An engineer must translate the PC1 IP address to 10.199.77.100 and permit PC1 to ping the loopback 0 on router R2. What command set must be used?

  

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 1357:

  A network engineer must configure an interface with IP address 10.10.10.145 and a subnet mask equivalent to 11111111.11111111.11111111.11111000. Which subnet mask must the engineer use?

  A. /29

  B. /30

  C. /27

  D. /28

  Correct Answer: A

• Question 1358:

  Refer lo the exhibit.

  

  What is the next-hop P address for R2 so that PC2 reaches the application server via ElGRP?

  A. 192.168.30.1

  B. 10.10 105

  C. 10.10.10.6

  D. 192.168.201

  Correct Answer: D

• Question 1359:

  Refer to the exhibit.

  

  An engineer assigns IP addressing to the current VLAN with three PCs. The configuration must also account for the expansion of 30 additional VLANS using the same Class C subnet for subnetting and host count. Which command set fulfills the request while reserving address space for the expected growth?

  A. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 265 255.255.252

  B. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.248

  C. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.0

  D. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255.255.255.128

  Correct Answer: B

  The scenario mentions that a Class C subnet needs to be used, which means we have a default subnet mask of 255.255.255.0. With the requirement to implement 30 additional VLANs, we need a subnet mask that will provide enough IP addresses for all these VLANs with the same Class C network . By allocating a /29 subnet to each VLAN, it will provide 6 bit host addresses (2^6 - 2, where 2 is subtracted for the network address and broadcast address) and will provide enough IP addresses for all 30 additional VLANs.

• Question 1360:

  Which channel-group mode must be configured when multiple distribution interfaces connected to a WLC are bundled?

  A. Channel-group mode passive.

  B. Channel-group mode on.

  C. Channel-group mode desirable.

  D. Channel-group mode active.

  Correct Answer: B
