Cisco CCNA 200-301 Questions & Answers

• Question 1:

  Which two WAN architecture options help a business scalability and reliability for the network? (Choose two)

  A. asychronous routing

  B. single-homed branches

  C. dual-homed branches

  D. static routing

  E. dynamic routing

  Correct Answer: CE

  The two WAN architecture options that help a business scalability and reliability for the network are:

  C. Dual-homed branches: Dual-homing involves connecting each branch office to two or more different WAN links, such as two different service providers, in order to provide redundancy and increase reliability. This architecture option enables the business to maintain network connectivity even if one of the WAN links fails. In addition, it can also provide better performance and scalability by balancing traffic across the multiple links.

  E. Dynamic routing: Dynamic routing protocols enable routers to dynamically exchange information about the network topology and find the best path for data to travel. This allows for faster convergence in case of network changes and improves network scalability by automatically adjusting to changes in the network. Dynamic routing protocols also increase network reliability by providing redundancy and failover mechanisms.

• Question 2:

  Which type of port is used to connect the wired network when an autonomous AP maps two VLANs to its WLANs?

  A. acceVss

  B. LAG

  C. trunk

  D. EtherChannel

  Correct Answer: C

• Question 3:

  Refer to the exhibit. Which router or router group are NTP clients?

  

  A. R1

  B. R2 and R3

  C. R1, R3, and R4

  D. R1, R2, and R3

  Correct Answer: D

  Pretty sure you have to have the NTP server configured before you can be a client

• Question 4:

  Which type of attack is mitigated by dynamic ARP inspection?

  A. DDoS

  B. malware

  C. man-in-the-middle

  D. worm

  Correct Answer: C

• Question 5:

  Which type of API allows SDN controllers to dynamically make changes to the network?

  A. northbound API

  B. REST API

  C. SOAP API

  D. southbound API

  Correct Answer: D

• Question 6:

  Refer to Exhibit.

  

  The loopback1 interface of the Atlanta router must reach the loopback3 interface of the Washington router. Which two static host routes must be configured on the NEW York router? (Choose two)

  A. ipv6 route 2000::1/128 2012::1

  B. ipv6 route 2000::3/128 2023::3

  C. ipv6 route 2000::3/128 s0/0/0

  D. ipv6 route 2000::1/128 2012::2

  E. ipv6 route 2000::1/128 s0/0/1

  Correct Answer: AB

  ipv6 [loopback network] [serial interface IP] IPv6: /128 provides a single IPv6 address

• Question 7:

  Which two statements about the purpose of the OSI model are accurate? (Choose two.)

  A. Defines the network functions that occur at each layer

  B. Facilitates an understanding of how information travels throughout a network

  C. Changes in one layer do not impact other layer

  D. Ensures reliable data delivery through its layered approach

  Correct Answer: AB

  OSI model is an structure for Both TCP and UDP. So it doesn't ensure reliabile delivery always (For UDP)

• Question 8:

  Which three statements about network characteristics are true? (Choose three.)

  A. Speed is a measure of the data rate in bits per second of a given link in the network.

  B. Scalability indicates how many nodes are currently on the network.

  C. The logical topology is the arrangement of cables, network devices, and end systems.

  D. Availability is a measure of the probability that the network will be available for use when it is required.

  E. Reliability indicates the dependability of the components that make up the network.

  Correct Answer: ADE

• Question 9:

  Which two statements about EtherChannel technology are true? (Choose two.)

  A. EtherChannel provides increased bandwidth by bundling existing FastEthernet or Gigabit Ethernet interfaces into a single EtherChannel.

  B. STP does not block EtherChannel links.

  C. You can configure multiple EtherChannel links between two switches, using up to a limit of sixteen physical ports.

  D. EtherChannel does not allow load sharing of traffic among the physical links within the EtherChannel.

  E. EtherChannel allows redundancy in case one or more links in the EtherChannel fail.

  Correct Answer: AE

• Question 10:

  Which three statements about MAC addresses are correct? (Choose three.)

  A. To communicate with other devices on a network, a network device must have a unique MAC address.

  B. The MAC address is also referred to as the IP address.

  C. The MAC address of a device must be configured in the Cisco IOS CLI by a user with administrative privileges.

  D. A MAC address contains two main components, the first of which identifies the manufacturer of the hardware and the second of which uniquely identifies the hardware.

  E. An example of a MAC address is 0A:26:B8: D6:65:90.

  F. A MAC address contains two main components, the first of which identifies the network on which the host resides and the second of which uniquely identifies the host on the network.

  Correct Answer: ADE
