Cisco CCNA 200-301 Questions & Answers

• Question 231:

  Which properly is shared by 10GBase-SR and 10GBase-LR interfaces?

  A. Both require fiber cable media for transmission.

  B. Both require UTP cable media for transmission.

  C. Both use the single-mode fiber type.

  D. Both use the multimode fiber type.

  Correct Answer: A

  10GBase-SR and 10GBase-LR are two types of 10 Gbps Ethernet standards for optical fiber communication.

  10GBase-SR (Short Reach) is a 10 Gbps Ethernet standard for short-distance optical fiber communication, typically used for data center and campus network applications. It supports distances up to 300 meters over multi-mode fiber (MMF) cable.

  10GBase-LR (Long Reach) is a 10 Gbps Ethernet standard for long-distance optical fiber communication, typically used for WAN (Wide Area Network) applications. It supports distances up to 10 kilometers over single-mode fiber (SMF) cable, making it well suited for high-speed inter-building or inter-data center connections.

• Question 232:

  Why implement VRRP?

  A. to provide end users with a virtual gateway in a multivendor network

  B. to leverage a weighting scheme to provide uninterrupted service

  C. to detect link failures without the overhead of Bidirectional Forwarding Detection

  D. to hand over to end users the autodiscovery of virtual gateways

  Correct Answer: A

• Question 233:

  Refer to the exhibit.

  

  How many objects are present in the given JSON-encoded data?

  A. one

  B. four

  C. seven

  D. nine

  Correct Answer: D

  Simply count all the opening or closing curly brackets that represent the start or closing of an object value. NOTE: there's an error on that exhibit, the opening bracket in the array is supposed to be an opening bracket.

• Question 234:

  What is the purpose of configuring different levels of syslog for different devices on the network?

  A. to rate-limit messages for different seventy levels from each device

  B. to set the severity of syslog messages from each device

  C. to identify the source from which each syslog message originated

  D. to control the number of syslog messages from different devices that are stored locally

  Correct Answer: B

  The purpose of configuring different levels of syslog for different devices on the network is to set the severity of syslog messages from each device.

• Question 235:

  Which IPv6 address range is suitable for anycast addresses for distributed services such DHCP or DNS?

  A. FF00:1/12

  B. 2001:db8:0234:ca3e::1/128

  C. 2002:db84:3f37:ca98:be05:8/64

  D. FE80::1/10

  Correct Answer: B

• Question 236:

  Refer to the exhibit.

  

  After configuring a new static route on the CPE. the engineer entered this series of commands to verify that the new configuration is operating normally. When is the static default route installed into the routing table?

  A. when 203 0 113.1 is no longer reachable as a next hop

  B. when the default route learned over external BGP becomes invalid

  C. when a route to 203.0 113 1 is learned via BGP

  D. when the default route over external BGP changes its next hop

  Correct Answer: B

• Question 237:

  Refer to the exhibit.

  

  A network engineer started to configure two directly-connected routers as shown. Which command sequence must the engineer configure on R2 so that the two routers become OSPF neighbors?

  A. interface GigabitEthernet0/1 ip ospf 1 area 1

  B. router ospf 1 network 192.168.12.1 0.0.0.0 area 1

  C. interface GigabitEthernet0/1 ip ospf 1 area 0

  D. router ospf 1 network 192.168.12.0 0.0.0.127 area 0

  Correct Answer: A

  To configure ospf in the interface ip ospf process-id area area-id

• Question 238:

  Refer to the exhibit.

  

  An administrator received a call from a branch office regarding poor application performance hosted at the headquarters. Ethernet 1 is connected between Router1 and the LAN switch. What identifies the issue?

  A. The QoS policy is dropping traffic.

  B. There is a duplex mismatch.

  C. The link is over utilized.

  D. The MTU is not set to the default value.

  Correct Answer: B

  The output shows that there are 15000 collisions on the interface, indicating a duplex mismatch issue between Router1 and the switch.

• Question 239:

  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.

  Correct Answer: B

  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 240:

  Refer to the exhibit.

  

  What is represented by "R1" and "SW1" within the JSON output?

  A. key

  B. array

  C. value

  D. object

  Correct Answer: C
