Cisco CCNA 200-301 Questions & Answers

• Question 171:

  Refer to the exhibit.

  

  A network administrator must permit traffic from the 10.10.0.0/24 subnet to the WAN on interlace Seria10. What is the effect of the configuration as the administrator applies the command?

  A. The permit command fails and returns an error code.

  B. The router accepts all incoming traffic to Seria10 with the last octet of the source IP set to 0.

  C. The sourced traffic from IP range 10.0.0.0 -10.0.0.255 is allowed on Seria10.

  D. The router fails to apply the access list to the interface.

  Correct Answer: D

  The router will fail to apply the ACL to the Serial interface because it doesn't use the right syntax. The right interface subcommand is: ip access-group 10 in. Also it would not work as intended because it includes the wrong subnet.

• Question 172:

  How does encryption project the wireless network?

  A. via integrity checks to identify wireless forgery attacks in the frame

  B. via specific ciphers to detect and prevent zero-day network attacks

  C. via an algorithm to change wireless data so that only the access point and client understand it

  D. via a policy to prevent unauthorized users from communicating on the wireless network

  Correct Answer: C

• Question 173:

  A packet from a company s branch office is destined to host 172.31.0.1 at headquarters. The sending router has three possible matches in its routing table for the packet prefixes:

  How does the router handle the packet?

  A. It sends the traffic via prefix 172.31.0.0/16

  B. It sends the traffic via the default gateway 0.0.0.070.

  D. R1(config)3|p route 0.0.0.0 0.0 0.0 192 168.0.2

  Correct Answer: B

• Question 176:

  What is a function of an endpoint?

  A. It is used directly by an individual user to access network services

  B. It passes unicast communication between hosts in a network

  C. It transmits broadcast traffic between devices in the same VLAN

  D. It provides security between trusted and untrusted sections of the network.

  Correct Answer: A

  An endpoint is a remote computing device that communicates back and forth with a network to which it is connected. Examples of endpoints include: Desktops. Laptops. Smartphones.

• Question 177:

  What is the definition of backdoor malware?

  A. malicious code that is installed onto a computer to allow access by an unauthorized user

  B. malicious code with the main purpose of downloading other malicious code

  C. malicious program that is used to launch other malicious programs

  D. malicious code that infects a user machine and then uses that machine to send spam

  Correct Answer: A

  Backdoor malware is a type of Trojan that allows attackers to gain remote access to a system by negating normal authentication procedures. Backdoor attacks let attackers gain control of system resources, perform network reconnaissance, and install different types of malwares. Backdoors can be installed in both software and hardware. There have been many high-profile backdoor attacks in recent years, including the SolarWinds attack in 2020, which was suspected to be carried out by nation-state actors. Backdoor attacks can be prevented by using strong passwords, keeping software up to date, and using security software. BTW, any type of malware can potentially be used to send spam

• Question 178:

  The clients and OHCP server reside on different subnets. Which command must be used to forward requests and replies between clients on the 10.10.0.1/24 subnet and the DHCP server at 192.168.10.1?

  A. ip route 192.168.10.1

  B. ip default-gateway 192.168.10.1

  C. ip helper-address 192.168.10.1

  D. ip dhcp address 192.168.10.1

  Correct Answer: C

• Question 179:

  Refer to the exhibit.

  

  A packet sourced from 10.10.10.32 is destined for the internet.

  A. 0

  B. 1

  C. 2

  D. 32

  Correct Answer: B

  The administrative distance for the destination route is 1 because the gateway of last resort is configured with an administrative distance of 1 (indicated by the [1/0] in the routing table output) and the destination route for the Internet (0.0.0.0/0) is learned via that gateway. Therefore, the correct answer is B. 1.

  Which access point mode must be selected?

  A. Lightweight with local switching disabled

  B. Local with AP fallback enabled

  C. OfficeExtend with high availability disabled

  D. FlexConnect with local switching enabled

  Correct Answer: D
