You have configured NAT for the below topology. However. NAT is not working. Looking at the provided output what is the issue? R2 Output: ip nat inside source static 192.168 .10 .254 209.165.201.5 interface serial 0/1/0 ip address 192.168.1.2 255.255.255.252 ip nat outside exit interface serial 0/1/1 ip address 209.165.200.1 255.255.255.252 ip nat inside Which router will become the DR and why? Which OSPF database are created and maintained by each router using OSPF messages? Adjacency Database, Link-state Database, Routing Database Neighbor Database, Link-state Database, Routing Database Neighbor Database, Link-state Database. Forwarding Database Adjacency Database, Link-state Database, Forwarding Database According to the below ACL entries what will happen to ICMP packet from source 10.30.0.10 IP to destination 10.20.0.10IP ? ip access-11st extended 101 remark ACL 101 fulfills policies 1,2 , and 3 10 deny tcp 10.30 .0 .00 .0 .0 .25510 .20 .0 .00 .0 .0 .255 eq 22 28 deny tcp 10.30.0.00.0.0.25510.20.0.00.0.0.255 eq mma 30 deny tcp 10.30.0.0 0..0.255 host 10.30 .0 .1 eq wow 40 deny tcp 10.30 .0 .00 .0 .0 .255 host 10.40 .0 .1 eq waw 50 deny tcp10.30.0.00.0.0.25510.20.0.0..0.255 eq 443 60 deny tcp 10.30 .0 .00 .0 .0 .255 host 10.30 .0 .1 eq 443 70 deny tcp 10.3e.0.0 0.0 .8 .255 host 10.40 .0 .1 eq 443 80 permit Icmp 30.40..0.0.0.25510.20.0.00.0.0.255 echo 100 perait ip any any Permitted due to the permit rule in line 80 Permitted due to the permit any any rule on line 100 Permitted due to the permit rule in line 90 Denied due to the default implicit deny rule at the end of the ACL If you have a single public IPv 4 and need to map it to many private IPV4 addresses, which NAT will you use? Port Address Translation (PAT) Static NAT One-to-One NAT Dynamic NAT Which is not a valid OSPF router state? ExStart Loading Exchange Start Init What is router ID used for by an OSPF-enabled router? (Select 2 ) Router uses router ID to select best route from the topology table. In a multiaccess LAN environment, the router with the highest router ID is elected the DR. Router will look for known router ID to form adjacency with other routers. Router with the highest router ID will send their database descriptor (DBD) packets first. Router with lower router ID is ignored for routing packets. What is the difference between Symmetric Encryption and Asymmetric Encryption? Symmetric algorithms are used for encryption of data but asymmetric algorithms are used for decryption of the encrypted data. Symmetric algorithms use the same pre-shared key to encrypt and decrypt data. Whereas, in asymmetric algorithms the key that is used for encryption is different from the key that is used for decryption. Symmetric algorithms are used for sending encrypted data and asymmetric algorithms are used for receiving encrypted data. Symmetric algorithms provides data confidentiality and asymmetric algorithms can provide data integrity
