• Question 1232:

  A network engineer must migrate a router loopback interface to the IPv6 address space. If the current IPv4 address of the interface is 10.54.73.1/32, and the engineer configures IPv6 address 0:0:0:0:0:ffff:a36:4901, which prefix length must be used?

  A. /64

  B. /96

  C. /124

  D. /128

  Correct Answer: D

  The equivalent subnet mask in IPv6 for an IPv4 /32 subnet mask is /128 and here're sample loopback interface config steps: configure terminal interface loopback 0 ipv6 address 2001:db8::1/128 no shutdown exit show interface loopback 0

• Question 1233:

  A Cisco engineer notices that two OSPF neighbors are connected using a crossover Ethernet cable. The neighbors are taking too long to become fully adjacent. Which command must be issued under the interface configuration on each router to reduce the time required for the adjacency to reach the FULL state?

  A. ip ospf dead-interval 40

  B. ip ospf network broadcast

  C. ip ospf priority 0

  D. ip ospf network point-to-point

  Correct Answer: D

  Because of ethernet (CSMA/CD) - With this cmd, we will avoid DR/BDR election.

  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.
