Cisco CCNA 200-301 Questions & Answers

• Question 511:

  Which type of IPv6 address is similar to a unicast address but is assigned to multiple devices on the same network at the same time?

  A. global unicast address

  B. anycast address

  C. multicast address

  D. link-local address

  Correct Answer: B

  An anycast address is similar to a unicast address but is assigned to multiple devices on the same network at the same time. When a device sends a packet to an anycast address, it is delivered to one of the devices with that address, selected based on the routing protocol's best-effort algorithm. This is useful for applications like load balancing and failover, where multiple devices provide the same service and it doesn't matter which one handles a particular request.

• Question 512:

  Correct Answer: B

• Question 513:

  What is a requirement for nonoverlapping Wi-Fi channels?

  A. different security settings

  B. discontinuous frequency ranges

  C. different transmission speeds

  D. unique SSIDs

  Correct Answer: B

  The requirement for non-overlapping Wi-Fi channels is that they must use discontinuous frequency ranges. Wi-Fi channels are defined by a specific frequency range, and adjacent channels overlap with each other. If two access points are using channels that overlap, they will cause interference and reduce the quality of the Wi-Fi network.

  To avoid interference, it's necessary to choose Wi-Fi channels that don't overlap. The most common Wi-Fi channels in use are 1, 6, and 11, and they don't overlap with each other. This means that if you have multiple access points in the same area, you can assign each access point a different channel from this set of channels to avoid interference.

  Different security settings, unique SSIDs, and different transmission speeds are not requirements for non-overlapping Wi-Fi channels, but they are important considerations for setting up a secure and efficient Wi-Fi network.

• Question 514:

  Refer to the exhibit. R1 learns all routes via OSPF

  A. R1(config)#ip route 192.168.20.0 255.255.0.0 192.168.30.2

  B. R1(config)#ip route 192.168.20.0 255.255.255.0 192.168.30.2 90

  C. R1(config)#ip route 192.168.20.0 255.255.255.0 192.168.30.2 111

  D. R1(config)#ip route 192.168.20.0 255.255.255.0 192.168.30.2

  Correct Answer: B

• Question 515:

  Refer to the exhibit. Router R1 resides in OSPF Area 0. After updating the R1 configuration to influence the paths that it will use to direct traffic, an engineer verified that each of the four Gigabit interfaces has the same route to 10.10.0.0/16. Which interface will R1 choose to send traffic to reach the route?

  

  A. GigabitEthernet0/0

  B. GigabltEthornet0/1

  C. GigabitEthernet0/2

  D. GigabitEthernet0/3

  Correct Answer: B

  ref BW 100000 MB

  ref BW BW G0/0 100000MB divided by 10000MB (or 10000000KB) = 10 cost

  G0/1 100000MB divided by 100000MB (or 100000000KB) = 1 cost

• Question 516:

  A. F0/10

  B. F0/11

  C. F0/12

  D. F0/13

  Correct Answer: B

  C. SwitchA(config-if)#switchport mode trunk SwitchA(config-if)#switchport trunk allowed vlan add 50, 51 SwitchA(config-if)#switchport voice vlan dot1p

  D. SwitchA(config-if)#switchport mode trunk SwitchA(config-if)#switchport trunk allowed vlan 50, 51 SwitchA(config-if)#mls qos trust cos

  Correct Answer: A

  First, we have to create the two VLANs:

  SW1(config)#vlan 100 SW1(config-vlan)#name COMPUTER SW1(config-vlan)#exit

  SW1(config)#vlan 101 SW1(config-vlan)#name VOIP SW1(config-vlan)#exit Now we can configure the interface:

  SW1(config)#interface GigabitEthernet 0/1 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 100 SW1(config-if)#switchport voice vlan 101 SW1(config-if)#exit We configure the interface in access mode and use VLAN 100 for the computer. The switchport voice vlan command tells the switch to use VLAN 101 as the voice VLAN.
