CCENT/CCNA Certification Quiz 2

Question 1:

You enter the partial configuration shown in a router.

interface s0/0
     ip address 160.1.1.1 255.255.255.252
     No shutdown
     ip nat outside

interface fa0/0
     ip address 10.2.2.254 255.255.255.0
     No shutdown
     ip nat inside

ip subnet-zero

ip nat pool first 66.150.4.49 66.150.4.54 netmask 255.255.255.248
ip nat inside source list 1 pool first

Access-list 1 permit 10.2.2.0 0.0.0.255

Which would be a valid "inside global address" after this router performs NAT?

10.2.2.1
66.150.4.53
66.150.4.48
10.2.2.254

Question 2:

Which best describes the wireless security standard that is defined by WPA? (Choose 2 statements)

It specifies the use of dynamic encryption keys that change each time a client establishes a connection
It specifies use of a static encryption key that must be changed frequently to enhance security

Question 3:

Your organization doubled in size during the past year and more growth is projected in the near future as shown in the exhibit:

Accounting: Currently 50 users. Projected growth 100 users
Marketing: Currently 20 users. Projected growth 60 users
IT: Currently 15 users. Projected growth 32 users
Client services: Currently 50 users. Projected growth 100 users

Currently all hosts in the organization are in the 10.20.20.0/24 range. What steps should you take to correct the situation and guarantee future expansion? Choose the best answer.

Change the subnet mask of all hosts to 255.255.255.0
No action, the current range will accommodate future growth
Change the subnet mask of all hosts to 255.255.254.0
Change the subnet mask of all hosts to 255.255.252.0

Question 4:

You are a network administrator at a branch office and have been assigned the 192.168.20.0/24 range for internal use. You need to subnet the range so 20 valid ip addresses are in the SERVER vlan, 32 valid ip addresses are in the EXECUTIVE vlan, 50 valid addresses are in the IT vlan, 50 for the ACCOUNTING vlan and the rest in the USERS vlan. At least 40 valid ip addresses must be in the USERS vlan. How would you accomplish this? (Choose the best answer)

Subnet as shown:
          SERVER: 192.168.20.0/27
          EXECUTIVE: 192.168.20.64/26
          IT: 192.168.20.128/26
          ACCOUNTING: 192.168.20.192/26
          USERS: 192.168.20.32/27

Subnet as shown:
          SERVER: 192.168.20.0/28
          EXECUTIVE: 192.168.20.32/26
          IT: 192.168.20.96/26
          ACCOUNTING: 192.168.20.160/26
          USERS: 192.168.20.224/27

Subnet as shown:
          SERVER: 192.168.20.0/27
          EXECUTIVE: 192.168.20.32/26
          IT: 192.168.20.96/26
          ACCOUNTING: 192.168.20.160/26
          USERS: 192.168.20.32/26

This cannot be accomplished with the current address space

<hrdata-mce-alt="Question 5" class="system-pagebreak" />

Question 5:

You are a network administrator at a branch office and received a router from the headquarters. You have been told the ip address of the router's eth0/0 interface is 192.168.1.254/24. You need to configure the router, but when attempting to locate a console cable, you cannot find one. What can you do to try to connect to the router? (Choose 3)

a) From your computer open up a tftp session to 192.168.1.254.
b) Connect a straight through cable between your computer and the router's eth0/0
c) Assign 192.168.1.255/24 to your computer's NIC
d) Connect a crossover cable between your computer and the router's eth0/0
e) Assign 192.168.1.1/24 to your computer's NIC
f) From your computer open up a telnet session to 192.168.1.254.

Question 6:

Exhibit

router configuration example

A junior network administrator enters the following configuration in the new routers:

R1 configuration
          interface fa0/0
          ip address 10.4.101.254 255.255.255.0
          no shutdown
          interface s0/0
          ip address 10.4.1.1 255.255.255.252
          no shutdown

R2 configuration
          Interface fa0/0
          10.4.102.254 255.255.255.0
          no shutdown
          interface s0/0
          ip address 10.4.1.2 255.255.255.252
          ip route 10.4.101.0 255.255.255.0 10.4.1.1

What is missing from the configuration so H1 can talk to H2?

Enable routing on R1
Nothing, the hosts should be able to ping each other
On R1, enter a static route to the 10.4.102.0/24 network pointing to R2
Enter cdp run on R1
