If you wanted to deny FTP access from network 200.200.10.0 to network 200.199.11.0 but allow everything else, which of the following command strings is valid?
Options- A. access-list 110 deny 200.200.10.0 to network 200.199.11.0 eq ftp
access-list 111 permit ip any 0.0.0.0 255.255.255.255 - B. access-list 1 deny ftp 200.200.10.0 200.199.11.0 any any
- C. access-list 100 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp
- D. access-list 198 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp
access-list 198 permit ip any 0.0.0.0 255.255.255.255 - Correct Answer
- access-list 198 deny tcp 200.200.10.0 0.0.0.255 200.199.11.0 0.0.0.255 eq ftp
access-list 198 permit ip any 0.0.0.0 255.255.255.255
ExplanationExtended IP access lists use numbers 100-199 and 2000-2699 and filter based on source and destination IP address, protocol number, and port number. The last option is correct because of the second line that specifies permit ip any any. (I used 0.0.0.0 255.255.255.255, which is the same as the any option.) The third option does not have this, so it would deny access but not allow everything else. - 1. You have an interface on a router with the IP address of 192.168.192.10/29.

Correct Answer: 192.168.192.15
Explanation:
A /29 (255.255.255.248) has a block size of 8 in the fourth octet. This means the subnets are 0, 8, 16, 24, etc. 10 is in the 8 subnet. The next subnet is 16, so 15 is the broadcast address.
Correct Answer: 192.168.19.26 255.255.255.248
Explanation:
A /29 is 255.255.255.248, which is a block size of 8 in the fourth octet. The subnets are 0, 8, 16, 24, 32, 40, etc. 192.168.19.24 is the 24 subnet, and since 32 is the next subnet, the broadcast address for the 24 subnet is 31. 192.168.19.26 is the only correct answer.
Correct Answer: VTP
Explanation:
Virtual Trunk Protocol (VTP) is used to pass a VLAN database to any or all switches in the switched network. The three VTP modes are server, client, and transparent.
Correct Answer: 1
Explanation:
By default, switches break up collision domains but are one large broadcast domain.
Correct Answer: 172.16.112.0
Explanation:
A /25 mask is 255.255.255.128. Used with a Class B network, the third and fourth octets are used for subnetting with a total of 9 subnet bits, 8 bits in the third octet and 1 bit in the fourth octet. Since there is only 1 bit in the fourth octet, the bit is either off or on-which is a value of 0 or 128. The host in the question is in the 0 subnet, which has a broadcast address of 127 since 128 is the next subnet.
Correct Answer: VTP is used to send VLAN information to switches in a configured VTP domain.
Explanation:
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link.
Correct Answer: About 350 feet
Explanation:
The IEEE 802.11b standard provides the lowest data rate at 1Mbps, but it also has the longest distance, which is about 350 feet.
Correct Answer: show ip eigrp neighbors
Explanation:
The
show ip eigrp neighbors command allows you to check the IP addresses as well as the retransmit interval and queue counts for the neighbors that have established an adjacency.
Correct Answer: So different networks could communicate.
Explanation:
The primary reason the OSI model was created was so that different networks could inter-operate.
Correct Answer: show version
Explanation:
The
show version command provides you with the current configuration register setting.
