5.
Refer to the exhibit. Host A is connected to the LAN, but it cannot get
access to any resources on the Internet. The configuration of the host
is shown in the exhibit. What could be the cause of the problem? • The host subnet mask is incorrect. • The default gateway is a network address. • The default gateway is a broadcast address. • The default gateway is on a different subnet from the host. 6. What subnet mask would a network administrator assign to a network address of 172.30.1.0 if it were possible to have up to 254 hosts? • 255.255.0.0 • 255.255.255.0 • 255.255.254.0 • 255.255.248.0 welcome to www.ccna-4.blogspot.com 7. Which three IP addresses are private? (Choose three.) • 10.35.66.70 • 192.168.99.5 • 172.18.88.90 • 192.33.55.89 • 172.35.16.5
8. Given the IP address and subnet mask of 172.16.134.64 255.255.255.224, which of the following would describe this address? • This is a useable host address. • This is a broadcast address. • This is a network address. • This is not a valid address.
9.
A router interface has been assigned an IP address of 172.16.192.166
with a mask of 255.255.255.248. To which subnet does the IP address
belong? • 172.16.0.0 • 172.16.192.0 • 172.16.192.128 • 172.16.192.160 • 172.16.192.168 • 172.16.192.176 10.
Refer to the exhibit. The network administrator has assigned the
internetwork of LBMISS an address range of 192.168.10.0. This address
range has been subnetted using a /29 mask. In order to accommodate a new
building, the technician has decided to use the fifth subnet for
configuring the new network (subnet zero is the first subnet). By
company policies, the router interface is always assigned the first
usable host address and the workgroup server is given the last usable
host address. Which configuration should be entered into the workgroup
server’s properties to allow connectivity to the network? • IP address: 192.168.10.38 subnet mask: 255.255.255.240 default gateway: 192.168.10.33 • IP address: 192.168.10.38 subnet mask: 255.255.255.248 default gateway: 192.168.10.33 • IP address: 192.168.10.39 subnet mask: 255.255.255.248 default gateway: 192.168.10.31 • IP address: 192.168.10.254 subnet mask: 255.255.255.0 default gateway: 192.168.10.1 11. Which of the following network devices are recommended to be assigned static IP addresses? (Choose three.) • LAN workstations • servers • network printers • routers • remote workstations • laptops 12. hich of the following are features of IPv6? (Choose three.) • faster routing protocols • data types and classes of service • authentication and encryption • improved host naming conventions • same addressing scheme as IPv4 13. What is the primary reason for development of IPv6? • security • header format simplification • expanded addressing capabilities • addressing simplification 14.
What two things will happen if a router receives an ICMP packet which
has a TTL value of 1 and the destination host is several hops away?
(Choose two.) • The router will decrement the TTL value and forward the packet to the next router on the path to the destination host. • The router will send a time exceeded message to the source host. • The router will increment the TTL value and forward the packet to the next router on the path to the destination host. • The router will send an ICMP Redirect Message to the source host. 15. Refer to the exhibit. Why would the response shown be displayed after issuing the command ping 127.0.0.1 on a PC? • The IP settings are not properly configured on the host. • Internet Protocol is not properly installed on the host. • There is a problem at the physical or data link layer. • The default gateway device is not operating. • A router on the path to the destination host has gone down.
16. How many bits make up an IPv4 address? • 64 • 48 • 32 17.
Refer to the exhibit. A network administrator discovers that host A is
having trouble with Internet connectivity, but the server farm has full
connectivity. In addition, host A has full connectivity to the server
farm. What is a possible cause of this problem? • Host A has an overlapping network address. • Host A has an incorrect default gateway configured. • Host A has an incorrect subnet mask. • NAT is required for the host A network. 18. What three facts are true about the network portion of an IPv4 address? (Choose three.) • identifies an individual device • is identical for all hosts in a broadcast domain • is altered as packet is forwarded • varies in length • is used to forward packets • uses flat addressing 19. What is a group of hosts called that have identical bit patterns in the high order bits of their addresses? • a network • an octet • a radix • Bottom of Form • Top of Form • Bottom of Form 20. What is the network address of the host 172.25.67.99 /23 in binary? • 10101100. 00011001.01000011.11111111 • 10101100. 00011001.01000010.00000000 • 10101100. 00011001.01000010.01100011 • 10101100. 00010001.01000011. 01100010 • 10101100. 00011001.00000000.00000000 21.
Refer to the exhibit. A network administrator has to develop an IP
addressing scheme that uses the 192.168.1.0 /24 address space. The
network that contains the serial link has already been addressed out of a
separate range. Each network will be allocated the same number of host
addresses. Which network mask will be appropriate to address the
remaining networks? • 255.255.255.224 • 255.255.255.192 • 255.255.255.240 • 255.255.255.128 • 255.255.255.252
