Which characteristic would most influence a network design engineer to select a multilayer switch over a Layer 2 switch?
Ability to build a routing table.

A network administrator is troubleshooting slow performance in a Layer 2 switched network. Upon examining the IP header, the administrator notices that the TTL value is not decreasing. Why is the TTL value not decreasing?
This is the normal behavior for a Layer 2 network.
100
What two conditions have to be met in order to form a cluster that includes 5 access points? (Choose two.) 1. Clustering mode must be enabled on the APs. 2. At least two controllers are needed to form the cluster. 3. The APs have to be connected on the same network segment. 4. The APs must all be configured to use different radio modes. 5. The APs must use different cluster names.
1 & 3
100
Which address is used by an IPv6 EIGRP router as the source for hello messages?
The interface IPv6 link-local address.
100
What is a difference between the Cisco IOS 12 and IOS 15 versions?
The IOS version 15 license key is unique to each device, whereas the IOS version 12 license key is not device specific.
200
A network designer is considering whether to implement a switch block on the company network. What is the primary advantage of deploying a switch block?
The failure of a switch block will not impact all end users.
200
A network administrator enters the spanning-tree portfast bpduguard default command. What is the result of this command being issued on a Cisco switch?
Any switch port that has been configured with PortFast will be error-disabled if it receives a BPDU.

A network engineer is troubleshooting a newly deployed wireless network that is using the latest 802.11 standards. When users access high bandwidth services such as streaming video, the wireless network performance is poor. To improve performance the network engineer decides to configure a 5 Ghz frequency band SSID and train users to use that SSID for streaming media services. Why might this solution improve the wireless network performance for that type of service?
The 5 GHz band has more channels and is less crowded than the 2.4 GHz band, which makes it more suited to streaming multimedia.
200
Which two statements are correct about EIGRP acknowledgment packets? (Choose two.) 1. The packets are sent in response to hello packets, 2. The packets are used to discover neighbors that are connected on an interface, 3. The packets are sent as unicast, 4. The packets require confirmation, 5. The packets are unreliable.
3 & 5
200
A network administrator issues the command R1(config)# license boot module c1900 technology-package securityk9 on a router. What is the effect of this command?
The Evaluation Right-To-Use license for the Security technology package is activated.
300
Which action should be taken when planning for redundancy on a hierarchical network design?
Add alternate physical paths for data to transverse the network.
300
An STP instance has failed and frames are flooding the network. What action should be taken by the network administrator?
Redundant links should be physically removed until the STP instance is repaired.
300
What method of wireless authentication is dependent on a RADIUS authentication server?
WPA2 Enterprise
300
When are EIGRP update packets sent?
Only when necessary
300
If a company wants to upgrade a Cisco 2800 router from IOS 12.4T, what IOS should be recommended for a stable router platform?
15.1M
400
Which technological factor determines the impact of a failure domain?
The role of the malfunctioning device.
400
A network engineer is configuring a LAN with a redundant first hop to make better use of the available network resources. Which protocol should the engineer implement?
Gateway Load Balancing Protocol (GLBP)
400
A remote classroom can successfully access video-intensive streaming lectures via wired computers. However, when an 802.11n wireless access point is installed and used with 25 wireless laptops to access the same lectures, poor audio and video quality is experienced. Which wireless solution would improve the performance for the laptops?
Add another access point.
400
When will a router that is running EIGRP put a destination network in the active state?
When the connection to the successor of the destination network fails and there is no feasible successor available.
400
What is the purpose of the Cisco PAK?
It is a key for enabling an IOS feature set.
500
What are three access layer switch features that are considered when designing a network? (Choose three.) 1. broadcast traffic containment 2. failover capability 3. forwarding rate 4. port density 5. Power over Ethernet 6. speed of convergence
3, 4, & 5
500
Which port role is assigned to the switch port that has the lowest cost to reach the root bridge?
Root Port.
500
What are the two methods that are used by a wireless NIC to discover an AP? (Choose two.) 1. sending an ARP request 2. delivering a broadcast frame 3. transmitting a probe request 4. initiating a three-way handshake 5. receiving a broadcast beacon frame
3 & 5
500
What are two reasons to implement passive interfaces in the EIGRP configuration of a Cisco router? (Choose two.) 1. to provide increased network security 2. to shut down unused interfaces 3. to avoid unnecessary update traffic 4. to mitigate attacks coming from the interfaces 5. to exclude interfaces from load balancing
1 & 3

Refer to the exhibit. A network administrator is attempting to upgrade the IOS system image on a Cisco 2901 router. After the new image has been downloaded and copied to the TFTP server, what command should be issued on the router before the IOS system image is upgraded on the router?
ping 10.10.10.2
