1. Question 831 · 1334 in bank

   What is the primary purpose of a First Hop Redundancy Protocol?

   • AIt allows directly connected neighbors to share configuration information
   • BIt reduces routing failures by allowing Layer 3 load balancing between OSPF neighbors that have the same link metric
   • CIt allows a router to use bridge priorities to create multiple loop-free paths to a single destination
   • DIt reduces routing failures by allowing more than one router to represent itself as the default gateway of a network

   Show answer

   Answer: D

   Explanation

   D is correct answer. Explanation: A first hop redundancy protocol (FHRP) is a computer networking protocol which is designed to protect the default gateway used on a subnetwork by allowing two or more routers to provide backup for that address; in the event of failure of an active router, the backup router will take over.

   An engineer is configuring NAT to translate the source subnet of 10.10.0.0/24 to any one of three addresses: 192.168.3.1, 192.168.3.2, or 192.168.3.3. Which configuration should be used?

   • Aenable configure terminal ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30 access-list 1 permit 10.10.0.0 0.0.0.255 ip nat outside destination list 1 pool mypool interface g1/1 ip nat inside interface g1/2 ip nat outside
   • Benable configure terminal ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30 access-list 1 permit 10.10.0.0 0.0.0.254 ip nat inside source list 1 pool mypool interface g1/1 ip nat inside interface g1/2 ip nat outside
   • Cenable configure terminal ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30 route map permit 10.10.0.0 255.255.255.0 ip nat outside destination list 1 pool mypool interface g1/1 ip nat inside interface g1/2 ip nat outside
   • Denable configure terminal ip nat pool mypool 192.168.3.1 192.168.3.3 prefix-length 30 access-list 1 permit 10.10.0.0 0.0.0.255 ip nat inside source list 1 pool mypool interface g1/1 ip nat inside interface g1/2 ip nat outside

   Show answer

   Answer: D

   Explanation

   D is the least incorrect, but still very not correct lol: prefix length 30 = 255.255.255.253 = 4-2 hosts = 2 hosts It actually "works" in PT but you have the broadcast address in your range which is no bueno. Prefix should be /29

3. Question 833 · 1334 in bank

   When the active router in an HSRP group fails, which router assumes the role and forwards packets?

   • Aforwarding
   • Blistening
   • Cstandby
   • Dbackup

   Show answer

   Answer: C

   Explanation

   HSRP is a Cisco proprietary protocol. VRRP is an open standard protocol. HSRP is an application layer protocol. VRRP is a network layer protocol. HSRP version 1 uses UDP port number 1985 and multicast address 224.0. Virtual Router Redundancy Protocol (VRRP) is a network management protocol that is used to increase the availability of default gateway servicing hosts on the same subnet. VRRP improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network. What is the VRRP protocol used for? The Virtual Router Redundancy Protocol (VRRP) eliminates the single point of failure inherent in the static default routed environment. VRRP specifies an election protocol that dynamically assigns responsibility for a virtual router (a VPN 3000 Series Concentrator cluster) to one of the VPN Concentrators on a LAN.

   What protocol allows an engineer to back up 20 network router configurations globally while using the copy function?

   • ATCP
   • BSMTP
   • CFTP
   • DSNMP

   Show answer

   Answer: C

   Explanation

   "While using the copy function." See: https://www.cisco.com/c/en/us/support/docs/ios-nx-os-software/ios-software-releases-122-mainline/46741-backup-config.html Under section "Use an FTP Server to Backup and Restore a Configuration", there is shown the command: copy running-config ftp: The answer is indisputably and undoubtedly C.

5. Question 835 · 1334 in bank

   Select 2

   Which two statements are true about the command ip route 172.16.3.0 255.255.255.0 192.168.2.4? (Choose two.)

   • AIt establishes a static route to the 172.16.3.0 network.
   • BIt establishes a static route to the 192.168.2.0 network.
   • CIt configures the router to send any traffic for an unknown destination to the 172.16.3.0 network.
   • DIt configures the router to send any traffic for an unknown destination out the interface with the address 192.168.2.4.
   • EIt uses the default administrative distance.
   • FIt is a route that would be used last if other routes to the same destination exist.

   Show answer

   Answer: AE

   Explanation

   correct answer is A&D A. The command "ip route 172.16.3.0 255.255.255.0 192.168.2.4" establishes a static route to the 172.16.3.0 network. This means that the router knows how to reach the devices in the 172.16.3.0 network, and it will use the interface with the address 192.168.2.4 to reach them. D. The command "ip route 172.16.3.0 255.255.255.0 192.168.2.4" also configures the router to send any traffic for an unknown destination out the interface with the address 192.168.2.4. This is because it's a default route (also known as the gateway of last resort), which means if the router doesn't have a specific route for a destination, it will send the traffic out through this interface. The other options (B, C, E, and F) do not accurately describe the behavior of the given command.

   Which two pieces of information can you determine from the output of the show ntp status command? (Choose two.)

   • Awhether the NTP peer is statically configured
   • Bthe IP address of the peer to which the clock is synchronized
   • Cthe configured NTP servers
   • Dwhether the clock is synchronized
   • Ethe NTP version number of the peer

   Show answer

   Answer: BD

   Explanation

   Below is the output of the ג€show ntp statusג€ command. From this output we learn that R1 has a stratum of 10 and it is getting clock from 10.1.2.1.

8. Question 838 · 1334 in bank

   Which keyword in a NAT configuration enables the use of one outside IP address for multiple inside hosts?

   • Asource
   • Bstatic
   • Cpool
   • Doverload

   Show answer

   Answer: D

   Explanation

   By adding the keyword ג€overloadג€ at the end of a NAT statement, NAT becomes PAT (Port Address Translation). This is also a kind of dynamic NAT that maps multiple private IP addresses to a single public IP address (many-to-one) by using different ports. Static NAT and Dynamic NAT both require a one-to-one mapping from the inside local to the inside global address. By using PAT, you can have thousands of users connect to the Internet using only one real global IP address. PAT is the technology that helps us not run out of public IP address on the Internet. This is the most popular type of NAT. An example of using ג€overloadג€ keyword is shown below: R1(config)# ip nat inside source list 1 interface ethernet1 overload

9. Question 839 · 1334 in bank

   Which feature or protocol determines whether the QOS on the network is sufficient to support IP services?

   • ALLDP
   • BCDP
   • CIP SLA
   • DEEM

   Show answer

   Answer: C

   Explanation

   Okay, for all you confused people. IP SLA was on the old CCNA 200-125 exam, which is now retired, as exam topic 7.2, stating you need to be able to "troubleshoot network connectivity issues using ICMP echo-based IP SLA." It is no longer on the current CCNA 200-301 exam. It seems ExamTopics, in their infinite wisdom, has decided to include questions from the previous 200-125 as part of their 200-301 dump. So ignore it, and move on.

10. Question 840 · 1334 in bank

    In QoS, which prioritization method is appropriate for interactive voice and video?

    • Atraffic policing
    • Bround-robin scheduling
    • Clow-latency queuing
    • Dexpedited forwarding

    Show answer

    Answer: C

    Explanation

    Some questions are tricky. They ask for prioritization method not queueing method, thus it leaves us with round-robin and expedited-forwarding. So correct answer is expedited forwarding.
