Cisco CCNA 200-301 Questions & Answers

• Question 771:

  What describes the functionality of southbound APIs?

  A. They enable communication between the controller and the network device.

  B. They communicate with the management plane.

  C. They use HTTP messages to communicate.

  D. They convey information from the controller to the SDN applications.

  Correct Answer: A

• Question 772:

  Which two types of attack are categorized as social engineering? (Choose two.)

  A. phoning

  B. malvertising

  C. probing

  D. pharming

  E. phishing

  Correct Answer: DE

• Question 773:

  What is a characteristic of private IPv4 addressing?

  A. simplifies the addressing in the network

  B. complies with PCI regulations

  C. reduces the forwarding table on network routers

  D. is used on hosts that communicate only with other internal hosts

  Correct Answer: D

• Question 774:

  What are two functions of a firewall within an enterprise? (Choose two.)

  A. It enables traffic filtering based on URLs.

  B. It serves as an endpoint for a site-to-site VPN in standalone mode.

  C. It provides support as an endpoint for a remote access VPN in multiple context mode.

  D. It offers Layer 2 services between hosts.

  E. It enables wireless devices to connect to the network.

  Correct Answer: AB

  A:Traffic Filtering based on URLs: A firewall can be configured to filter network traffic based on Uniform Resource Locators (URLs) or website addresses. This feature allows organizations to enforce web access policies by blocking or allowing specific URLs or categories of websites.

  B:Endpoint for Site-to-Site VPN in Standalone Mode: A firewall can act as an endpoint for a site-to-site Virtual Private Network (VPN) connection. In this mode, the firewall establishes secure communication tunnels between different locations or networks, ensuring the confidentiality and integrity of data transmitted over the VPN.

• Question 775:

  What is a characteristic of private IPv4 addressing?

  A. is used when the ISP requires the new subnet to be advertised to the internet for web services

  B. provides unlimited address ranges

  C. is used when the network has multiple endpoint listeners

  D. alleviates the shortage of IPv4 addresses

  Correct Answer: D

• Question 776:

  What is a characteristic of an SSID in wireless networks?

  A. identifies an access point on a WLAN

  B. uses the password to connect to an access point

  C. uses policies to prevent unauthorized users

  D. uses a case-sensitive text string

  Correct Answer: D

• Question 777:

  What is a characteristic of private IPv4 addressing?

  A. is used without allocation from a regional internet authority

  B. is used when traffic on the subnet must traverse a site-to-site VPN to an outside organization

  C. reduces the forwarding table on network routers

  D. provides unlimited address ranges

  Correct Answer: A

• Question 778:

  What is a characteristic of private IPv4 addressing?

  A. reduces network complexity

  B. is used on hosts that communicate only with other internal hosts

  C. simplifies the addressing in the network

  D. reduces network maintenance costs

  Correct Answer: B

• Question 779:

  What is a characteristic of encryption in wireless networks?

  A. identifies an access point on a WLAN

  B. uses the password to connect to an access point

  C. uses integrity checks to identify forgery attacks in the frame

  D. uses authentication protocols to secure a network

  Correct Answer: D

  Encryption can also be used to verify the identity of the communicating parties by requiring the use of authentication protocols, such as WPA2-PSK or EAP-TLS, to establish a secure connection.

• Question 780:

  How is RFC 1918 addressing used in a network?

  A. They are used to access the Internet from the internal network without conversion.

  B. They are used in place of public addresses for Increased security.

  C. They are used with NAT to preserve public IPv4 addresses.

  D. They are used by Internet Service Providers to route over the Internet.

  Correct Answer: C

  "This document describes address allocation for private internets. The allocation permits full network layer connectivity among all hosts inside an enterprise as well as among all public hosts of different enterprises. The cost of using private internet address space is the potentially costly effort to renumber hosts and networks between public and private."
