Cisco 200-301 Online Practice Questions and Exam Preparation

Cisco 200-301 Online Questions & Answers

• Question 1201:

  Refer to the exhibit.

  

  Which configuration for RTR-1 deniess SSH access from PC-1 to any RTR-1 interface and allows all other traffic?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 1202:

  Which type of DNS record is used to specify the mail server responsible for accepting email messages on behalf of a recipient's domain?

  A. MX record
  B. TXT record
  C. SRV record
  D. A record
  A. MX record

  ---

  An MX record identifies the mail servers that handle email for a domain and their priority. When an email is sent, the sending mail server queries the DNS for the MX records of the recipient's domain to know where to deliver the email.

• Question 1203:

  Which IPv6 address is the equivalent of the IPv4 interface loopback address 127.0.0.1?

  A. ::1
  B. ::
  C. 2000::/3
  D. 0::/10
  A. ::1

  ---

  In IPv6 the loopback address is written as, ::1

  This is a 128bit number, with the first 127 bits being '0' and the 128th bit being '1'. It's just a single address, so could also be written as ::1/128.

• Question 1204:

  Which AP mode is used for capturing wireless traffic and forwarding that traffic to a PC that is running a packet analyzer?

  A. bridge
  B. monitor
  C. rouge detector
  D. sniffer
  D. sniffer

  ---

  The controller enables you to configure an access point as a network "sniffer", which captures and forwards all the packets on a particular channel to a remote machine that runs packet analyzer software. These packets contain information on time stamps, signal strength, packet sizes, and so on.

• Question 1205:

  Refer to the exhibit.

  

  A network engineer executes the show ip route command on router D. What is the next hop to network 192.168 1 0/24 and why?

  A. The next hop is 10.0.2.1 because it uses distance vector routing
  B. The next hop is 10.0.2.1 because it is a link-state routing protocol
  C. The next hop is 10.0.0.1 because it has a better administrative distance
  D. The next hop is 10.0.0.1 because it has a higher metric.
  B. The next hop is 10.0.2.1 because it is a link-state routing protocol

  EIGRP is not running on LAN side of the router, so it's going to be redistributed, so it's external EIGRP route ... so the AD is 170 vs 110 via the OSPF route.

• Question 1206:

  Which command is used to specify the delay time in seconds for LLDP to initialize on any interface?

  A. lldp timer
  B. lldp tlv-select
  C. lldp reinit
  D. lldp holdtime
  C. lldp reinit

  ---

  1. lldp holdtime seconds: Specify the amount of time a receiving device should hold the information from your device before discarding it

  2. lldp reinit delay: Specify the delay time in seconds for LLDP to initialize on an interface

  3. lldp timer rate: Set the sending frequency of LLDP updates in seconds

• Question 1207:

  DRAG DROP

  Drag and drop the statements about device management from the left onto the corresponding device-management types on the right.

  Select and Place:

  

  

• Question 1208:

  Which command is used to enable LLDP globally on a Cisco IOS ISR?

  A. lldp run
  B. lldp enable
  C. lldp transmit
  D. cdp run
  E. cdp enable
  A. lldp run

  ---

  Link Layer Discovery Protocol (LLDP) is an industry standard protocol that allows devices to advertise, and discover connected devices, and there capabilities (same as CDP of Cisco). To enable it on Cisco devices, we have to use this command under global configuration mode:

  Sw(config)# lldp run

• Question 1209:

  An engineer is configuring remote access to a router from IP subnet 10.139.58.0/28. The domain name, crypto keys, and SSH have been configured. Which configuration enables the traffic on the destination router?

  A. line vty 0 15 access-class 120 in ! ip access-list extended 120 permit tcp 10.139.58.0 0.0.0.15 any eq 22
  B. interface FastEthernet0/0 ip address 10.122.49.1 255.255.255.252 ip access-group 10 in ! ip access-list standard 10 permit udp 10.139.58.0 0.0.0.7 host 10.122.49.1 eq 22
  C. interface FastEthernet0/0 ip address 10.122.49.1 255.255.255.252 ip access-group 110 in ! ip access-list standard 110 permit tcp 10.139.58.0 0.0.0.15 eq 22 host 10.122.49.1
  D. line vty 0 15 access-group 120 in ! ip access-list extended 120 permit tcp 10.139.58.0 0.0.0.15 any eq 22
  A. line vty 0 15 access-class 120 in ! ip access-list extended 120 permit tcp 10.139.58.0 0.0.0.15 any eq 22

  ---

  For an ACL that specifies the source, destination, and port numbers, an extended ACL is required. For VTY access filtering, the access-class command is used, as opposed to the access-group command, which is reserved for physical interfaces.

• Question 1210:

  How do TCP and UDP differ in the way they provide reliability for delivery of packets?

  A. TCP does not guarantee delivery or error checking to ensure that there is no corruption of data, UDP provides message acknowledgement and retransmits data if lost.
  B. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing
  C. TCP is a connectionless protocol that does not provide reliable delivery of data; UDP is a connection-oriented protocol that uses sequencing to provide reliable delivery.
  D. TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake.
  B. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing

  Ref: CCNA 200-301 Official Cert Guide, Volume 2

  "Chapter 1. Introduction to TCP/IP Transport and Applications

  ...

  Flow Control Using Windowing

  TCP implements flow control by using a window concept that is applied to the amount of data that can be outstanding and awaiting acknowledgment at any one point in time.

  ...

  User Datagram Protocol

  UDP provides a service for applications to exchange messages. Unlike TCP, UDP is connectionless and provides no reliability, no windowing, no reordering of the received data, and no segmentation of large chunks of data into the right size for transmission.
