質問 # 448
Refer to the exhibit.
A network administrator must permit SSH access to remotely manage routers in a network. The operations team resides on the 10.20.1.0/25 network. Which command will accomplish this task?
- A. no access-list 2699 deny ip any 10.20.1.0 0.0.0.255
- B. no access-list 2699 deny tcp any 10.20.1.0 0.0.0.127 eq 22
- C. access-list 2699 permit udp 10.20.1.0 0.0.0.255
- D. access-list 2699 permit tcp any 10.20.1.0 0.0.0.255 eq 22
正解：A
解説：
Explanation
Note : Already a statement is there in last to allow SSH Traffic for network 10.20.1.0 0.0.0.127, but Second statement says deny ip any 10.20.1.0 0.0.0.255, so how it will work once it is denied. So the right answer is remove the --- no access-list 2699 deny ip any 10.20.1.0 0.0.0.255.
質問 # 449
Which protocol prompts the Wireless LAN Controller to generate its own local web administration SSL certificate for GUI access?
- A. HTTP
- B. TACACS+
- C. HTTPS
- D. RADIUS
正解：C
解説：
You can protect communication with the GUI by enabling HTTPS. HTTPS protects HTTP browser sessions by using the Secure Sockets Layer (SSL) protocol.
When you enable HTTPS, the controller generates its own local web administration SSL certificate and automatically applies it to the GUI. You also have the option of downloading an externally generated certificate.

質問 # 453
Refer to the exhibit.
The loopback1 interface of the Atlanta router must reach the lookback3 interface of the Washington router.
- A. ipv6 route 2000::1/128 2012::2
- B. ipv6 route 2000:3 123 s0/0/0
- C. ipv6 route 2000::1/128 2012::1
- D. ipv6 route 2000::3/128 2023::3
- E. ipv6 route 2000::1/128 s0/0/1
正解：C、D
質問 # 454
Refer to the exhibit.
Based on the LACP neighbor status, in which mode is the SW1 port channel configured?
- A. active
- B. mode on
- C. passive
- D. auto
正解：A
解説：
From the neighbor status, we notice the "Flags" are SP. "P" here means the neighbor is in Passive mode. In order to create an Etherchannel interface, the (local) SW1 ports should be in Active mode. Moreover, the "Port State" in the exhibit is "0x3c" (which equals to "00111100 in binary format). Bit 3 is "1" which means the ports are synchronizing -> the ports are working so the local ports should be in Active mode.
質問 # 455
Refer to the exhibit.
Traffic that is flowing over interface TenGigabitEthernet0/0 experiences slow transfer speeds. What is the reason for the issue?
- A. queuing drops
- B. a duplex incompatibility
- C. heavy traffic congestion
- D. a speed conflict
正解：D
質問 # 456
Refer to the exhibit.
A network administrator assumes a task to complete the connectivity between PC A and the File Server. Switch A and Switch B have been partially configured with VLAN 10, 11, 12, and 13. What is the next step in the configuration?
- A. Add PC A to VLAN 10 and the File Server to VLAN 11 fa VLAN segmentation
- B. Add a router on a stick between Switch A and Switch B allowing for Inter-VLAN routing.
- C. Add VLAN 13 to the trunk links on Switch A and Switch B for VLAN propagation
- D. Add PC A to the same subnet as the Fie Server allowing for intra-VLAN communication.
正解：C
質問 # 457
A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented?
(Choose two)
- A. runts
- B. giants
- C. frame
- D. input errors
- E. CRC
正解：D、E
解説：
Explanation
Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the frame and counts it as some kind of input error.
Cisco switches list this error as a CRC error. Cyclic redundancy check (CRC) is a term related to how the FCS math detects an error.
The "input errors" includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts.
The output below show the interface counters with the "show interface s0/0/0" command:
質問 # 458
Refer to the exhibit. What does route 10.0.1.3/32 represent in the routing table?
- A. the 10.0.0.0 network
- B. all hosts in the 10.0.1.0 subnet
- C. a single destination address
- D. the source 10.0.1.100
正解：A
質問 # 459
Where does a switch maintain DHCP snooping information?
- A. in the CAM table
- B. in the MAC address table
- C. in the frame forwarding database
- D. in the binding database
正解：D
解説：
A DHCP table is built that includes the source MAC address of a device on an untrusted port and the IP address assigned by the DHCP server to that device. The MAC address and IP address are bound together. Therefore, this table is called the DHCP snooping binding table.
質問 # 460
Which type of address is the public IP address of a NAT device?
- A. inside public
- B. insride local
- C. outside public
- D. outside global
- E. inside global
- F. outsdwde local
正解：E
解説：
NAT use four types of addresses:
* Inside local address - The IP address assigned to a host on the inside network. The address is usually not an IP address assigned by the Internet Network Information Center (InterNIC) or service provider.
This address is likely to be an RFC 1918 private address.
* Inside global address - A legitimate IP address assigned by the InterNIC or service provider that represents one or more inside local IP addresses to the outside world.
* Outside local address - The IP address of an outside host as it is known to the hosts on the inside network.
* Outside global address - The IP address assigned to a host on the outside network. The owner of the host assigns this address.
