DHCP server. The output of the debug ip dhcp server command shows “DHCPD: there is no

address pool for 10.1.1.1″. What is the problem?

The 10.1.1.1 address is already configured on Fa0/0.

The default router for the 10Network pool is incorrect.

Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP

request that enters interface s0/0/0 and is destined for an FTP server at IP address

192.168.1.5?

The router matches the incoming packet to the statement that was created by the access-list

201 deny icmp 192.168.1.0 0.0.0.255 any command, continues comparing the packet to the

remaining statements in ACL 201 to ensure that no subsequent statements allow FTP, and then

the router drops the packet.

The router reaches the end of ACL 101 without matching a condition and drops the packet

because there is no statement that was created by the access-list 101 permit ip any any

command.

The router matches the incoming packet to the statement that was created by the access-list

101 permit ip any 192.168.1.0 0.0.0.255 command and allows the packet into the router.

It matches the incoming packet to the statement that was created by the access-list 201 permit

ip any any command and allows the packet into the router.

to this situation?

Scheduling will be easy if the network and software teams work independently.

It will be difficult to isolate the problem if two teams are implementing changes independently.

Results from changes will be easier to reconcile and document if each team works in isolation.

Only results from the software package should be tested as the network is designed to

accommodate the proposed software platform.

There are a few errors overall:

#3 should be “The mapping between DLCI 100 and 172.16.3.1 was learned through

Inverse ARP.” DLCI’s refer to frame relay and do not use DHCP.

#19 should be “They begin with the FE80::/10 prefix.” and “They are assigned to a

host by a stateless autoconfiguration process.” The keyword is “local”

The second answer is missing from #41 and should be “Telnet to 172.16.20.0/24 is

denied.”

#50 should be “access-list 10 deny 192.168.16.32 0.0.0.15″ the .32 subnet with a

wildcard mask 0.0.0.15 (255.255.255.240 if it were subnet mask) will cover

192.168.16.32 through 192.168.16.47

#27 should be Line passwords are encrypted with type 7 encryption.

#53 is c)

Faulty network interface cards (NICs) can be the cause of network transmission errors

due to late collisions, short frames, and jabber. Jabber is often defined as the condition

in which a network device continually transmits random, meaningless data onto the

network. Other likely causes of jabber are faulty or corrupt NIC driver files, bad

cabling, or grounding problems.
