Cisco 200-301 Online Questions & Answers

• Question 801:

  Refer to the exhibit. Router R1 currently is configured to use R3 as the primary route to the Internet, and the route uses the default administrative distance settings. A network engineer must configure R1 so that it uses R2 as a backup, but only if R3 goes down. Which command must the engineer configure on R1 so that it correctly uses R2 as a backup route, without changing the administrative distance configuration on the link to R3?

  

  A. ip route 0.0.0.0 0.0.0.0 g0/1 1
  B. ip route 0.0.0.0 0.0.0.0 209.165.201.5 10
  C. ip route 0.0.0.0 0.0.0.0 209.165.200.226 1
  D. ip route 0,0.0.0 0.0.0.0 g0/1 6
  D. ip route 0,0.0.0 0.0.0.0 g0/1 6

  Important thing to take note of is, the syntax for creating a default static route or connected static route uses the exit interface or output interface of source device (that's the interface on which all packets are sent to the destination network). Some of us may confuse and think to use Gi0/0 interface on R3 in the command, but the interface to configure the backup route here must use the exit interface on the R1 itself i.e. Gi0/1. So command will be: ip route 0.0.0.0 0.0.0.0 g0/1 6 ("6" here is AD that's greater than the connected route's AD i.e., 1)

• Question 802:

  What is the purpose of traffic shaping?

  A. to provide fair queuing for buffered flows
  B. to mitigate delays over slow links
  C. to limit the bandwidth that a flow can use
  D. to be a marking mechanism that identifies different flows
  A. to provide fair queuing for buffered flows

  ---

  Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time

• Question 803:

  B. Gateway of last resort is 172.16.1.1 to network 0.0.0.0 O E2 10.0.0.0/8 [110/5] via 192.168.1.1, 0:01:00, Ethernet0
  C. Gateway of last resort is 172.16.1.1 to network 0.0.0.0 O E2 10.0.0.0/24 [110/5] via 192.168.3.1, 0:01:00, Ethernet2
  D. Gateway of last resort is 172.16.1.1 to network 0.0.0.0 O E2 10.0.0.0/16 [110/5] via 192.168.2.1, 0:01:00, Ethernet1 O E2 10.0.0.0/24 [110/5] via 192.168.3.1, 0:01:00, Ethernet2
  A. Gateway of last resort is 172.16.1.1 to network 0.0.0.0 O E2 10.0.0.0/8 [110/5] via 192.168.1.1, 0:01:00, Ethernet0 O E2 10.0.0.0/16 [110/5] via 192.168.2.1, 0:01:00, Ethernet1 O E2 10.0.0.0/24 [110/5] via 192.168.3.1, 0:01:00, Ethernet2

• Question 804:

  DRAG DROP

  Refer to the exhibit.

  

  Drag and drop the networking parameters from the left onto the correct values on the right.

  Select and Place:

  

  

• Question 805:

  When deploying a new network that includes both Cisco and third-party network devices, which redundancy protocol avoids the interruption of network traffic if the default gateway router fails?

  A. VRRP
  B. FHRP
  C. GLBP
  D. HSRP
  A. VRRP

• Question 806:

  Refer to the exhibit.

  

  What is the effect of this configuration?

  A. The switch discards all ingress ARP traffic with invalid MAC-to-IP address bindings.
  B. All ARP packets are dropped by the switch.
  C. Egress traffic is passed only if the destination is a DHCP server.
  D. All ingress and egress traffic is dropped because the interface is untrusted.
  A. The switch discards all ingress ARP traffic with invalid MAC-to-IP address bindings.

  ---

  Dynamic ARP inspection is an ingress security feature; it does not perform any egress checking.

• Question 807:

  How are the switches in a spine-and-leaf topology interconnected?

  A. Each leaf switch is connected to one of the spine switches.
  B. Each leaf switch is connected to two spine switches, making a loop.
  C. Each leaf switch is connected to each spine switch.
  D. Each leaf switch is connected to a central leaf switch, then uplinked to a core spine switch.
  C. Each leaf switch is connected to each spine switch.

  ---

  In spine-leaf two-tier architecture, every lower-tier switch (leaf layer) is connected to each of the top-tier switches (spine layer) in a full-mesh topology. The leaf layer consists of access switches that connect to devices such as servers. The spine layer is the backbone of the network and is responsible for interconnecting all leaf switches. Every leaf switch connects to every spine switch. Typically a Layer 3 network is established between leaves and spines, so all the links can be used simultaneously.

• Question 808:

  What is the role of nonoverlapping channels in a wireless environment?

  A. to reduce interference
  B. to allow for channel bonding
  C. to stabilize the RF environment
  D. to increase bandwidth
  A. to reduce interference

  ---

  The role of nonoverlapping channels in a wireless environment is to reduce interference between wireless devices. In wireless networks, such as Wi-Fi networks, different devices transmit data wirelessly using specific frequency bands. These frequency bands are divided into channels, which act as virtual pathways for data transmission.

  When multiple wireless devices operate in close proximity and use overlapping channels, there is a potential for interference. Interference occurs when devices in overlapping channels transmit signals simultaneously, leading to signal degradation and reduced performance.

  Nonoverlapping channels are spaced far enough apart to minimize interference between adjacent channels. By assigning wireless devices to nonoverlapping channels, network administrators can reduce interference and improve overall network performance. This allows devices operating on different channels to transmit data without significantly overlapping with adjacent channels.

  Therefore, the primary role of nonoverlapping channels in a wireless environment is to reduce interference, enhancing the stability and reliability of wireless communication.

• Question 809:

  Which two statements about eBGP neighbor relationships are true? (Choose two.)

  A. The two devices must reside in different autonomous systems
  B. Neighbors must be specifically declared in the configuration of each device
  C. They can be created dynamically after the network statement is configured
  D. The two devices must reside in the same autonomous system
  E. The two devices must have matching timer settings
  A. The two devices must reside in different autonomous systems
  B. Neighbors must be specifically declared in the configuration of each device

• Question 810:

  What is a similarity between global and unique local IPv6 addresses?

  A. They use the same process for subnetting.
  B. They are part of the multicast IPv6 group type.
  C. They are routable on the global internet.
  D. They are allocated by the same organization.
  A. They use the same process for subnetting.

  ---

  Unique local addresses are NOT assigned by an organization.

  https://en.wikipedia.org/wiki/Unique_local_address

  A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00::/7.[1] Its purpose in IPv6 is somewhat analogous to IPv4 private network addressing, but with significant differences. Unique local addresses may be used freely, without centralized registration, inside a single site or organization or spanning a limited number of sites or organizations. They are routable only within the scope of such private networks, but not in the global IPv6 Internet.
