New Questions 3
What SNMP message alerts the manager to a condition on the network?
A. response
B. get
C. trap
D. capture
Answer: C
Explanation:
An agent can send unsolicited traps to the manager. Traps are messages alerting the SNMP manager to a condition on the network. Traps can mean improper user authentication, restarts, link status (up or down), MAC address tracking, closing of a TCP connection, loss of connection to a neighbor, or other significant events.

New Questions 4
You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each. Which IP address range meets these requirements?
A. 10.188.31.0/26
B. 10.188.31.0/25
C. 10.188.31.0/28
D. 10.188.31.0/27
E. 10.188.31.0/29
Answer: D
Explanation:
Each subnet has 30 hosts < 32 = 25 so we need a subnet mask which has at least 5 bit 0s
-> /27. Also the question requires the maximum number of subnets (which minimum the number of hosts-per-subnet) so /27 is the best choice.
New Questions 5
Which three are characteristics of an IPv6 anycast address? (Choose three.)
A. one-to-many communication model
B. one-to-nearest communication model
C. any-to-many communication model
D. a unique IPv6 address for each device in the group
E. the same address for multiple devices in the group
F. delivery of packets to the group interface that is closest to the sending device
Answer: B,E,F
Explanation:
A new address type made specifically for IPv6 is called the Anycast Address. These IPv6 addresses are global addresses, these addresses can be assigned to more than one interface unlike an IPv6 unicast address. Anycast is designed to send a packet to the nearest interface that is a part of that anycast group.
The sender creates a packet and forwards the packet to the anycast address as the destination address which goes to the nearest router. The nearest router or interface is found by using the metric of a routing protocol currently running on the network. However in a LAN setting the nearest interface is found depending on the order the neighbors were learned. The anycast packet in a LAN setting forwards the packet to the neighbor it learned about first.
New Questions 6
Which two statements describe characteristics of IPv6 unicast addressing? (Choose two.)
A. Global addresses start with 2000::/3.
B. Link-local addresses start with FE00:/12.
C. Link-local addresses start with FF00::/10.
D. There is only one loopback address and it is ::1.
E. If a global address is assigned to an interface, then that is the only allowable address for the interface.
Answer: A,D
Explanation:
Below is the list of common kinds of IPv6 addresses:
New Questions 7
Which protocol can cause overload on a CPU of a managed device?
A. Netflow
B. WCCP
C. IP SLA
D. SNMP
Answer: D
Explanation:
Sometimes, messages like this might appear in the router console:
%SNMP-3-CPUHOG: Processing [chars] of [chars]
They mean that the SNMP agent on the device has taken too much time to process a request.
You can determine the cause of high CPU use in a router by using the output of the show process cpu command.
Note: A managed device is a part of the network that requires some form of monitoring and management (routers, switches, servers, workstations, printersu2026).
New Questions 8
An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below.
Click the console connected to RouterC and issue the appropriate commands to answer the questions.
Which will fix the issue and allow ONLY ping to work while keeping telnet disabled?
A. Correctly assign an IP address to interface fa0/1.
B. Change the ip access-group command on fa0/0 from u201cinu201d to u201coutu201d.
C. Removeaccess-group 106 infrom interface fa0/0 and addaccess-group 115 in.
D. Removeaccess-group 102 outfrom interface s0/0/0 and addaccess-group 114 in
E. Removeaccess-group 106 infrom interface fa0/0 and addaccess-group 104 in.
Answer: E
Explanation:
Letu2021s have a look at the access list 104:
The question does not ask about ftp traffic so we donu2021t care about the two first lines. The 3rd line denies all telnet traffic and the 4th line allows icmp traffic to be sent (ping). Remember that the access list 104 is applied on the inbound direction so the 5th line u201caccess-list 104 deny icmp any any echo-replyu201d will not affect our icmp traffic because the u201cecho-replyu201d message will be sent over the outbound direction.

Scenario
Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.
The EIGRP routing protocol is configured.
You are required to troubleshoot and resolve the EIGRP issues between the various routers.
Use the appropriate show commands to troubleshoot the issues.
The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32, and 10.4.4.6/32 are not appearing in the routing table of R5. Why are the interfaces missing?
A. The interfaces are shutdown, so they are not being advertised.
B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.
C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
D. The loopback addresses haven't been advertised, and the network command is missing on R4.
Answer: B
Explanation:
For an EIGRP neighbor to form, the following must match:
- Neighbors must be in the same subnet
- K values
- AS numbers
- Authentication method and key strings
Here, we see that R4 is configured for EIGRP AS 2, when it should be AS 1.
New Questions 10
What are three factors a network administrator must consider before implementing Netflow in the network? (Choose three.)
A. CPU utilization
B. where Netflow data will be sent
C. number of devices exporting Netflow data
D. port availability
E. SNMP version
F. WAN encapsulation
Answer: A,B,C
Explanation:
NetFlow has a reputation for increasing CPU utilization on your network devices. Cisco's performance testing seems to indicate that newer hardware can accommodate this load pretty well, but you will still want to check it out before you turn on the feature. Some symptoms of high CPU utilization are very large jitter and increased delay. Services running on the device may also be affected.
Another thing to keep in mind is the amount of data you're going to be sending across the network. Depending on how much traffic you have and how you configure it, the traffic can be substantial. For example, you may not want to send NetFlow data from a datacenter switch to a NetFlow collector on the other side of a small WAN circuit. Also bear in mind that the flows from aggregating large numbers of devices can add up.

New Questions 11
When a DHCP server is configured, which two IP addresses should never be assignable to hosts? (Choose two.)
A. network or subnetwork IP address
B. broadcast address on the network
C. IP address leased to the LAN
D. IP address used by the interfaces
E. manually assigned address to the clients
F. designated IP address to the DHCP server
Answer: A,B
Explanation:
Network or subnetwork IP address (for example 11.0.0.0/8 or 13.1.0.0/16) and broadcast address (for example 23.2.1.255/24) should never be assignable to hosts. When try to assign these addresses to hosts, you will receive an error message saying that they canu2021t be assignable.
New Questions 12
When you are troubleshooting an ACL issue on a router, which command would you use to verify which interfaces are affected by the ACL?
A. show ip access-lists
B. show access-lists
C. show interface
D. show ip interface
E. list ip interface
Answer: D
Explanation:
Incorrect:
show ip access-lists does not show interfaces affected by an ACL.
