Cisco CCNA 200-301 Questions & Answers

• Question 251:

  Refer to the exhibit.

  

  An engineer must configure router R2 so it is elected as the DR on the WAN subnet.

  Which command sequence must be configured?

  A. interface gigabitethernet0/0 ip address 10.0.0.34 255.255.255.248 ip ospf priority 0

  B. interface gigabitethernet0/0 ip address 10.0.0.34 255.255.255.224 ip ospf priority 100

  C. interface gigabitethernet0/0 ip address 10.0.1.1 255.255.255.0 ip ospf priority 255

  D. interface gigabitethernet0/0 ip address 10.0.1.1 255.255.255.224 ip ospf priority 98

  Correct Answer: B

  Network on G0/0 is 10.0.0.32/27 ===> 10.0.0.34 255.255.255.224 with priority higher then default (1) , 100

• Question 252:

  Which two IPv6 addresses are used to provide connectivity between two routers on a shared link? (Choose two)

  A. FF02::0001:FF00:0000/104

  B. ff06:bb43:cc13:dd16:1bb:ff14:7545:234d

  C. 2002::512:1204b:1111::1/64

  D. 2001:701:104b:1111::1/64

  E. ::ffff:10.14.101.1/96

  Correct Answer: DE

  the IPv6 address "::ffff:10.14.101.1/96" is a valid representation of an IPv6 address with an embedded IPv4 address. This format is known as IPv4-mapped IPv6 address.

  In this case, "::ffff:10.14.101.1" represents the IPv4 address "10.14.101.1" embedded within an IPv6 address. The "::ffff:" prefix indicates that the following part of the address is an IPv4 address. The "/96" suffix indicates the network prefix length, specifying that the first 96 bits represent the network portion of the address.

• Question 253:

  Refer to the exhibit.

  

  Which entry is the longest prefix match for host IP address 192.168.10.5?

  A. 1

  B. 2

  C. 3

  D. 4

  Correct Answer: B

• Question 254:

  What does the implementation of a first-hop redundancy protocol protect against on a network?

  A. root-bridge loss

  B. spanning-tree loops

  C. default gateway failure

  D. BGP neighbor flapping

  Correct Answer: C

• Question 255:

  In a cloud-computing environment what is rapid elasticity?

  A. control and monitoring of resource consumption by the tenant

  B. automatic adjustment of capacity based on need

  C. pooling resources in a multitenant model based on need

  D. self-service of computing resources by the tenant

  Correct Answer: B

  Rapid elasticity in cloud computing refers to the cloud's capability to scale quickly to meet demand. Consumers benefit from rapid elasticity because they can expand or reduce their resources how and when they would like.

• Question 256:

  When a switch receives a frame for an unknown destination MAC address, how is the frame handled?

  A. broadcast to all ports on the switch

  B. flooded to all ports except the origination port

  C. forwarded to the first available port

  D. inspected and dropped by the switch

  Correct Answer: B

• Question 257:

  What is a reason to configure a trunk port that connects to a WLC distribution port?

  A. Eliminate redundancy with a link failure in the data path.

  B. Allow multiple VLAN to be used in the data path.

  C. Provide redundancy if there is a link failure for out-of-band management.

  D. Permit multiple VLANs to provide out-of-band management.

  Correct Answer: B

  distribution port is connected to the wired network( distribution system) and used for data traffic, and usually it's trunk which allows multiple vlans

• Question 258:

  Which type of IPv4 address type helps to conserve the globally unique address classes?

  A. multicast

  B. private

  C. loopback

  D. public

  Correct Answer: B

• Question 259:

  Refer to the exhibit.
