1. Question 791 · 1334 in bank

   Select 2

   Which two statements about the purpose of the OSI model are accurate? (Choose two.)

   • ADefines the network functions that occur at each layer
   • BFacilitates an understanding of how information travels throughout a network
   • CChanges in one layer do not impact other layer
   • DEnsures reliable data delivery through its layered approach

   Show answer

   Answer: AB

   Explanation

   A & B are correct C is incorrect because changes in one layer definitely affects others; imagine affecting layer 1 (disconnect a cable, plug it incorrectly, administer the incorrect amount of voltage, etc), it would affect other layers. D is incorrect because OSI model is not meant to ensure anything, it simply explains some of the features of each layer it defines.

   Select 2

   What are two benefits of FHRPs? (Choose two.)

   • AThey allow encrypted traffic
   • BThey prevent loops in the Layer 2 network.
   • CThey are able to bundle multiple ports to increase bandwidth
   • DThey enable automatic failover of the default gateway
   • EThey allow multiple devices to serve as a single virtual gateway for clients in the network

   Show answer

   Answer: DE

   Explanation

   The correct benefits of First Hop Redundancy Protocols (FHRPs) are: D. They enable automatic failover of the default gateway. FHRPs, such as HSRP (Hot Standby Router Protocol), VRRP (Virtual Router Redundancy Protocol), and GLBP (Gateway Load Balancing Protocol), provide redundancy for the default gateway. In the event of a primary router failure, one of the backup routers takes over as the default gateway, ensuring continuous network connectivity. E. They allow multiple devices to serve as a single virtual gateway for clients in the network. FHRPs allow multiple routers to share a virtual IP address as the default gateway. This provides load balancing and redundancy for client devices in the network. Therefore, the correct choices are D and E.

3. Question 793 · 1334 in bank

   What is the MAC address used with VRRP as a virtual address?

   • A00-05-42-38-53-31
   • B00-00-5E-00-01-0a
   • C00-00-0C-07-AD-89
   • D00-07-C0-70-AB-01

   Show answer

   Answer: B

   Explanation

   It is important for work as a network engineer, if you are troubleshooting issues and you see those MAC addresses you will know instantly to look at your FHRP's instead of trying to debug something unrelated

4. Question 794 · 1334 in bank

   Why would VRRP be implemented when configuring a new subnet in a multivendor environment?

   • Awhen a gateway protocol is required that supports more than two Cisco devices for redundancy
   • Bto interoperate normally with all vendors and provide additional security features for Cisco devices
   • Cto ensure that the spanning-tree forwarding path to the gateway is loop-free
   • Dto enable normal operations to continue after a member failure without requiring a change in a host ARP cache

   Show answer

   Answer: D

   Explanation

   I can only confirm the first half of B to be true unable to find anything on how VRRP provides security. So I picked D as D is 100% how VRRP works.

5. Question 795 · 1334 in bank

   Why implement VRRP?

   • ATo hand over to end users the autodiscovery of virtual gateways
   • BTo provide end users with a virtual gateway in a multivendor network
   • CTo leverage a weighting scheme to provide uninterrupted service
   • DTo detect link failures without the overhead of Bidirectional Forwarding Detection

   Show answer

   Answer: B

   Explanation

   A. Wrong, it;s DHCP that allows the auto discovery of (virtual) gateways, not VRRP C. Wrong, no weighting scheme is used between the gateways in the VRRP group. Active-passive scheme only D. Wrong, with VRRP users do not detect failure. If one GW fails, another one seamlessly takes up the role

6. Question 796 · 1334 in bank

   Which type of address is shared by routers in a HSRP implementation and used by hosts on the subnet as their default gateway address?

   • Amulticast address
   • Bvirtual IP address
   • Cloopback IP address
   • Dbroadcast address

   Show answer

   Answer: B

   Explanation

   HSRP allows multiple routers on a single LAN to share a virtual IP and MAC address which is configured as the default gateway on the hosts.

7. Question 797 · 1334 in bank

   By default, which virtual MAC address does HSRP group 14 use?

   • A00:05:5e:19:0c:14
   • B00:05:0c:07:ac:14
   • C04:15:26:73:3c:0e
   • D00:00:0c:07:ac:0e

   Show answer

   Answer: D

   Explanation

   As you know that HSRP uses this virtual MAC address, 0000.0C07.ACxy, where xy is the HSRP group number in hexadecimal. so your HSRP group no is 14 which is in a decimal format so we need to change it into hexadecimal 14 = 0000 1110 binary 0000 1110 = 0e hex so by this process, for HSRP Group 14 the Mac address will be : 00:00:0c:07ac:0e

8. Question 798 · 1334 in bank

   

   Refer to the exhibit. Router R1 is added to the network and configured with the 10.0.0.64/26 and 10.0.20.0/26 subnets. However, traffic destined for the LAN on R3 is not accessible. Which command when executed on R1 defines a static route to reach the R3 LAN?

   • Aip route 10.0.0.64 255.255.255.192 10.0.20.3
   • Bip route 10.0.15.0 255.255.255.0 10.0.20.1
   • Cip route 10.0.15.0 255.255.255.192 10.0.20.1
   • Dip route 10.0.15.0 255.255.255.0 10.0.20.3

   Show answer

   Answer: D

   Explanation

   We need to specify the destination network (10.0.15.0/24) and the next hop IP of the router to get to that network (10.0.20.3).

9. Question 799 · 1334 in bank

   A router has two static routes to the same destination network under the same OSPF process. How does the router forward packets to the destination if the net- hop devices are different?

   • AThe router chooses the route with the oldest age.
   • BThe router chooses the next hop with the lowest IP address.
   • CThe router chooses the next hop with the lowest MAC address.
   • DThe router load-balances traffic over all routes to the destination.

   Show answer

   Answer: D

   Explanation

   B. The router chooses the next hop with the lowest IP address. Administrative distance takes precedence over factors like the age of the route or the MAC address of the next hop. It is used to prioritize routes when there are multiple paths to the same destination, allowing the router to select the most appropriate route based on administrative distance values
