Cisco CCNA 200-301 Questions & Answers

• Question 21:

  Which Cisco proprietary protocol ensures traffic recovers immediately, transparently, and automatically when edge devices or access circuits fail?

  A. FHRP

  B. VRRP

  C. HSRP

  D. SLB

  Correct Answer: D

  The Cisco proprietary protocol that ensures traffic recovers immediately, transparently, and automatically when edge devices or access circuits fail is option D. SLB (Server Load Balancing).

  SLB is a feature within Cisco devices that allows for the distribution of incoming network traffic across multiple servers to improve performance and reliability. While SLB primarily focuses on load balancing server traffic, it can also help in recovering traffic when edge devices or access circuits fail.

  Options A (FHRP), B (VRRP), and C (HSRP) are First Hop Redundancy Protocols (FHRPs) used for providing redundancy and high availability for the default gateway in a local network. They are not specifically designed to handle traffic recovery when edge devices or access circuits fail.

• Question 22:

  Refer to the exhibit.

  

  Packets are flowing from 192.168.10.1 to the destination at IP address 192.168.20.75. Which next hop will the router select for the packet?

  A. 10.10.10.1

  B. 10.10.10.11

  C. 10.10.10.12

  D. 10.10.10.14

  Correct Answer: C

  To determine the next hop for the packet from 192.168.10.1 to the destination IP address 192.168.20.75, we need to find the most specific matching route in the routing table. Let's analyze the given routing table:

  192.168.20.0/26 (90/24513456) via 10.10.10.1 192.168.20.0/24 (120/5) via 10.10.10.2 192.168.20.0/27 (90/4123710) via 10.10.10.12 192.168.20.0/25 (90/14464211) via 10.10.10.11 0.0.0.0/0 (1/0) via 10.10.10.14 The destination IP address 192.168.20.75 falls within the following subnets:

  192.168.20.0/26 192.168.20.0/24 192.168.20.0/27 192.168.20.0/25 Among these, the most specific match (with the longest prefix) is the /27 subnet (3rd entry). Thus, the router will select the next hop 10.10.10.12 for the packet.

• Question 23:

  What are two purposes of HSRP? (Choose two.)

  A. It provides a mechanism for diskless clients to autoconfigure their IP parameters during boot.

  B. It improves network availability by providing redundant gateways.

  C. It groups two or more routers to operate as one virtual router.

  D. It passes configuration information to hosts in a TCP/IP network.

  E. It helps hosts on the network to reach remote subnets without a default gateway.

  Correct Answer: BC

• Question 24:

  What are two benefits for using private IPv4 addressing? (Choose two.)

  A. They allow for Internet access from IoT devices.

  B. They alleviate the shortage of public IPv4 addresses.

  C. They provide a layer of security from internet threats.

  D. They supply redundancy in the case of failure.

  E. They offer Internet connectivity to endpoints on private networks.

  Correct Answer: BC

• Question 25:

  Refer to the exhibit.

  

  Routers R1 and R2 are configured with RIP as the dynamic routing protocol. A network engineer must configure R1 with a floating static route to service as a backup route to network 192.168.23. which command must the engineer configure on R1?

  A. ip route 192.168.23.0 255.255.255.0 192.168,13.3 100

  B. ip route 192.168.23.0 255.255.255.255 192.168.13.3 121

  C. ip route 192.168.23.0 255.255.255.0 192.168.13.3 121

  D. ip route 192.168.23.0 255.255.255.0 192.168.13.3

  Correct Answer: C

  Floating route must have AD greater than primary route via RIP which has AD of 120.

• Question 26:

  Refer to the exhibit.

  

  According to the output, which parameter set is validated using the routing table of R7?

  A. R7 is missing a gateway of last resort. R7 is receiving routes that were redistributed in EIGRP. R7 will forward traffic destined to 10.90.8.0/24.

  B. R7 has a gateway of last resort available. R7 is receiving routes that were redistributed from BGP. R7 will drop traffic destined to 10.90.8.0/24.

  C. R7 is missing a gateway of last resort. R7 is receiving routes that were redistributed from BGP. R7 will forward traffic destined to 10.90.8.0/24.

  D. R7 has a gateway of last resort available. R7 is receiving routes that were redistributed in EIGRP.

  R7 will drop traffic destined to 10.90.8.0/24.

  Correct Answer: D

  EX = redistributed in EIGRP. We don't know for sure from what source these routes were redistributed.

• Question 27:

  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.

  Correct Answer: A

  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.

• Question 28:

  Refer to the exhibit.

  

  With which metric does router R1 learn the route to host 172.16.0.202?

  A. 90

  B. 110

  C. 32445

  D. 3184439

  Correct Answer: C

• Question 29:

  Refer to the exhibit.

  

  A network engineer must configure the link with these requirements:

  1.

  Consume as few IP addresses as possible.

  2.

  Leave at least two additional useable IP addresses for future growth.

  Which set of configurations must be applied?

  A. R1(config-if)#ip address 10.10.10.1 255.255.255.252 R2(config-if)#ip address 10.10.10.2 255.255.255.252

  B. R1(config-if)#ip address 10.10.10.1 255.255.255.240 R2(config-if)#ip address 10.10.10.12 255.255.255.240

  C. R1(config-if)#ip address 10.10.10.1 255.255.255.248 R2(config-if)#ip address 10.10.10.4 255.255.255.248

  D. R1(config-if)#ip address 10.10.10.1 255.255.255.0 R2(config-if)#ip address 10.10.10.5 255.255.255.0

  Correct Answer: C

  As per the exhibit, there's a requirement to configure the link and also keep 2 spare IP addresses for future use. So, calculate like this:

  2 IPs for Network ID and broadcast IP for whatever subnet we use.

  2 IPs for connected interfaces on each router i.e. 1 for R1 gi0/0/0 and 1 for R2 gi0/0/0.

  2 IPs reserved for future use.

  In this way, we need atleast 6 IPs here and the subnet that can provide a closest value in terms of total required IPs is /29 (255.255.255.248). The /29 subnet provides a total of 8 IPs addresses per subnet and out of that 6 are host usable IPs.

  So, for given subnet 10.10.10.X/29 we can have IP range from 10.10.10.0 - 10.10.10.7. Where 10.10.10.0 will be network ID and 10.10.10.7 will be broadcast IP. Rest 10.10.10.1 - 10.10.10.6 can be used to assign to any hosts of links.

• Question 30:

  Refer to the exhibit.

  

  A packet that is sourced from 172.16.3.254 is destined for the IP address of GigabitEthernet0/0/0. What is the subnet mask of the destination route?

  A. 0.0.0.0

  B. 255.255.254.0

  C. 255.255.255.0

  D. 255.255.255.255

  Correct Answer: C

  A connected route represents the network address. It uses the actual subnet prefix (mask). A local route represents the host address. It always uses the subnet prefix /32.Dec 20, 2021 Connected Routes and Local Routes Explained ComputerNetworkingNotes https://www.computernetworkingnotes.com › connected-.
