CORRECT ANSWERS { GRADED A+}
Which area of the network typically provides the platform for WAN connectivity?
- ✔✔Edge Distribution
You want to choose a fast, scalable non-proprietary routing protocol for your
network, what is the best choice? - ✔✔OSPF
Which of the following are functions of dynamic routing protocol? - ✔✔They
dynamically adapt to network changes, They determine the optimal path between
different segments in the network, They exchange network reachability
information between routers
Which of the following are factors to be considered for network scalability? -
✔✔Number of routes
Routing protocols
Number of adjacent networks
,Match the routing protocol to the protocol type: - ✔✔Path Vector Protocol = BGP
Distance Vector Protocol = EIGRP, RIPv2
Link State Protocol = OSPF, IS-IS
Which of the following are benefits of route summarization? - ✔✔Fewer routing
updates
Smaller routing table
Improved convergence
How fast a network stabilizes after a change is known as what? - ✔✔Convergence
Which of the following are Interior Gateway Protocol? - ✔✔OSPF, EIGRP, RIP
What are the four steps to router summarization? - ✔✔Count the number of
subnets
Find the power of 2 for the number of subnets identified in step 1
Reduce (subtract) the value of the prefix notation mask by the number you find in
step 2
Append the new subnet mask determined in step 3 to the first subnet in the range
,Match the network traffic type to its description: - ✔✔Anycast-introduced with
IPv6, and address can be assigned to an interface on more than one node
Multicast-traffic is sent to multiple destinations at the same time
Broadcast-used for sending traffic to all devices in the subnet
Unicast-traffic is exchanged only between one sender and one receiver
Which of the following can you use to securely connect remote locations to the
headquarters? - ✔✔VPNs
What type of interface is recommended to overcome NBMA network limitations? -
✔✔Point-to-Point subinterface
Multicast addresses are commonly used in IPv6 because there are no broadcast
addresses. Which prefix do they use? - ✔✔FF00::/8
Which problems can occur in NMBA topologies? - ✔✔Neighbor discovery can
be difficult for OSPF
Split horizon in EIGRP
Distance-vector protocols need additional configuration
, Which type of network can support many routers, but does not have the broadcast
capability? - ✔✔NBMA
Match each DMVPN component with its function: - ✔✔IPsec - provides key
management and transmission protection
NHRP - provides dynamic mutual discovery of spokes
Mgre - provides a scalable tunneling framework
What is the role of IPsec in DMVPN solutions? - ✔✔Encryption of traffic
between peers
Authentication of peers
Which of the following are types of tunneling VPNs? - ✔✔Mgre
Gre
DMVPN
Which of the following are characteristics of Mgre configuration? - ✔✔Only one
tunnel interface needs to be configured on a router to support multiple remote GRE
peers
Devices using Mgre require NHRP to build dynamic GRE tunnel
