Cisco 200-301 Online Questions & Answers

• Question 1491:

  Which technology allows for logical Layer 3 separation on physical network equipment?

  A. Virtual Route Forwarding
  B. Virtual Switch System
  C. IPsec Transport Mode
  D. Time Division Multiplexer
  A. Virtual Route Forwarding

• Question 1492:

  Refer to the exhibit.

  

  The route for 10.227.150.160/27 has been very unstable. The same route has four backups to routers A, B, C, and D via the respective methods. The routing protocol defaults for router Y have not been changed. When the current route for 10.227.150.160/27 becomes unavailable, which router will router Y use to route traffic to 10.227.150.160/27?

  A. router B
  B. router D
  C. router C
  D. router A
  A. router B

  ---

  To determine which router Router Y will use as a backup to route traffic to 10.227.150.160/27, we need to compare the administrative distances (AD) of the various routing methods that connect to routers A, B, C, and D.

  Routing Protocol Administrative Distances:

  OSPF (Router A): Default AD is 110.

  Static Route with an AD of 105 (Router B): The AD has been set to 105, making it lower than OSPF.

  External EIGRP (Router C): Default AD for external EIGRP is 170.

  iBGP (Router D): Default AD is 200.

  Current Route:

  The current route to 10.227.150.160/27 is through BGP (as shown by the 'B' in the routing table) via 10.224.1.3 with an AD of 20. This means that when this BGP route becomes unavailable, Router Y will select the next route based on the lowest AD.

  Backup Route Selection:

  Router B (Static Route): AD is 105.

  Router A (OSPF): AD is 110.

  Router C (External EIGRP): AD is 170.

  Router D (iBGP): AD is 200.

  The static route via Router B has the lowest administrative distance (AD of 105) among the available backups. Therefore, when the BGP route becomes unavailable, Router Y will use the static route via Router B to reach 10.227.150.160/27.

• Question 1493:

  Which two components are part of the control plane of a router? (Choose two.)

  A. Routing table calculation
  B. Frame forwarding
  C. Path selection
  D. CRC generation
  E. Packet queuing
  A. Routing table calculation
  C. Path selection

  ---

  The control plane is responsible for making routing decisions and building the routing table. Path selection and routing table calculation occur in the control plane. Frame forwarding, CRC generation, and packet queuing are functions of the data plane.

• Question 1494:

  What must a network administrator consider when deciding whether to configure a new wireless network with APs in autonomous mode or APs running in cloud-based mode?

  A. Autonomous mode APs are less dependent on an underlay but more complex to maintain than APs in cloud-based mode.
  B. Cloud-based mode APs relay on underlays and are more complex to maintain than APs in autonomous mode.
  C. Cloud-based mode APs are easy to deploy but harder to automate than APs in autonomous mode.
  D. Autonomous mode APs are easy to deploy and automate than APs in cloud-based mode.
  A. Autonomous mode APs are less dependent on an underlay but more complex to maintain than APs in cloud-based mode.

• Question 1495:

  What is a practice that protects a network from VLAN hopping attacks?

  A. Implement port security on internet-facing VLANs
  B. Enable dynamic ARP inspection
  C. Assign all access ports to VLANs other than the native VLAN
  D. Configure an ACL to prevent traffic from changing VLANs
  C. Assign all access ports to VLANs other than the native VLAN

• Question 1496:

  Refer to the exhibit.

  

  An engineer must configure the interface that connects to PC 1 and secure it in a way that only PC1 is allowed to use the port No VLAN tagging can be used except for a voice VLAN. Which command sequence must be entered to configure the switch?

  A. SW1(config-if)#switchport mode dynamic auto SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security violation restrict
  B. SW1(config-if)#switchport mode nonegotiate SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security maximum 1
  C. SW1(config-if)#switchport mode access SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security mac-address 0050.7966.6800
  D. SW1(config-if)#switchport mode dynamic desirable SW1(config-if)#switchport port-security mac-address 0050.7966.6800 SW1(config-if)#switchport port-security mac-address sticky
  C. SW1(config-if)#switchport mode access SW1(config-if)#switchport port-security SW1(config-if)#switchport port-security mac-address 0050.7966.6800

• Question 1497:

  Which option about JSON is true?

  A. uses predefined tags or angle brackets () to delimit markup text
  B. used to describe structured data that includes arrays
  C. used for storing information
  D. similar to HTML, it is more verbose than XML
  B. used to describe structured data that includes arrays

• Question 1499:

  Which set of 2.4 GHz nonoverlapping wireless channels is standard in the United States?

  A. channels 2, 7, 9, and 11
  B. channels 1, 6, 11, and 14
  C. channels 2, 7, and 11
  D. channels 1, 6, and 11
  D. channels 1, 6, and 11

  ---

  In the United States, while channels 1-13 can be used for 2.4 GHz WiFi, only three channels are considered non-overlapping (channels 12 and 13 are allowed under low powered conditions, but for most cases are not used). For best results, it is highly recommended to keep the 2.4 GHz channels to 1, 6, and 11, as these channel settings will allow for virtually no overlap in the WiFi signal. Shown below is a channel graph from WiFi Scanner showing three access points configured for channels 1, 6, and 11. As you can see, the center of each signal is at 1, 6, and 11 with the actual signal extending over several channels to the left and right.

• Question 1500:

  When a client and server are not on the same physical network, which device is used to forward requests and replies between client and server for DHCP?

  A. DHCP relay agent
  B. DHCP server
  C. DHCPDISCOVER
  D. DHCPOFFER
  A. DHCP relay agent

  ---

  A DHCP relay agent is any host that forwards DHCP packets between clients and servers. Relay agents are used to forward requests and replies between clients and servers when they are not on the same physical subnet.
