A company lists this equipment in their network design: Two Catalyst 4503 Layer 3 switches One 5500 security appliance firewall Two Catalyst 6509 switches Two lightweight access points Two Catalyst 2960 switches

Which two types of devices from the list would be appropriate to use at the access layer to provide end-user connectivity? (Choose two.) Catalyst 4503 switches Cisco 5500 security appliance firewall Catalyst 6509 switches lightweight access points Catalyst 2960 switches

A state-funded college wants to implement Cisco wireless IP phones for employees to use while on campus. The college currently has only wired network device access. Which two devices must be incorporated into the network design to best accommodate roaming for wireless IP phones? (Choose two.) voice VLAN capable switch autonomous AP PoE switch Cisco wireless LAN controller 2960 switch with 48 100-Mb ports lightweight access points

Which statement applies to a large network with thousands of nodes? Each wireless phone is normally in a separate VLAN for security reasons. Multiple firewalls exist throughout the access layer for maximum security protection. Firewalls cannot be implemented in the multilayer switches and routers. Intrusion detection is more likely to be performed by a separate device rather than integrated into a switch or router.

What type of WAN service is Frame Relay? dedicated cell switched packet switched circuit switched

What are three features of a Catalyst 2960 switch? (Choose three.) network layer functionality redundant power availability route summarization SNMP switch clustering inter-VLAN routing

Which three design requirements are implemented at the access layer? (Choose three.) PoE VLANs high-density routing packet filtering rapidly converging routing protocols QoS traffic classification and marking

Refer to the exhibit. What is an advantage of having two links connected between the two switches shown?

provides redundancy in case one of the switches fails provides connectivity to Switch1 when the link to the server fails provides connectivity when one of the connections between the switches fails provides power to the other switch when the other switch has lost AC power

When considering converged network designs, it is important to identify appropriate service demands. What is a concern when preparing a network design to fit this environment? business data compensation for sensitivity to noise location and placement of firewalls voice-level quality of service security policy requirements

What limitations of the 2960 switch prevent it from providing the services needed in the Distribution layer? It is limited to copper connections. It does not support QoS. It does not support voice VLAN capability. It does not perform route summarization.

Which rule should be followed when implementing the security requirements of a network design? Always use a common security plan for all business needs. As standard practice, lower access restrictions for users if cost is too high. Avoid reducing security in order to add additional network capabilities. When possible, implement an IDS to protect users from spam.

Which two factors should be considered when designing a wireless LAN that provides seamless roaming capabilities? (Choose two.) use of a wireless controller to manage IP addressing type of routing protocols location of existing wired clients coverage position of MDF

A network designer is evaluating the network security implementation for an organization. The designer recommends adding network security devices in front of the server farm, although network security devices have been deployed in the Enterprise Edge for two years. What type of attack can be effectively prevented with this recommendation? virus attack internal attack Internet attack phishing attack

Refer to the exhibit. The branch office needs constant access to the servers in the enterprise headquarters. Therefore, a backup Frame Relay link is added. A network administrator is configuring the routers in the branch office to make sure that when the backup Frame Relay link is used, only the traffic to access the enterprise headquarters is allowed. Which statement is true about the routing configuration on branch office edge routers?

The command ip route 0.0.0.0 0.0.0.0 serial 0/0 50 should be configured on BE2. The command ip route 128.107.0.0 255.255.0.0 serial 0/0 50 should be configured on BE1. The command ip route 128.107.0.0 255.255.0.0 serial 0/0 50 should be configured on BE2. The command ip route 192.135.250.0 255.255.255.0 serial 0/0 50 should be configured on BE1.

To reduce office overhead, a downtown company now requires that their customer service representatives work from home. All of the employees are located either downtown or in a nearby suburban area. Each employee requires high speed service and connectivity to the Internet through their local ISP. Which term describes this WAN service? DSL ATM T1 line Frame Relay

A network designer is selecting a WAN technology for connections between the headquarters of an organization and its branch offices. In this context, what is one advantage of choosing Frame Relay over a T1 line? more secure flexible bandwidth shared media across the link efficiency with fixed length packet size

Which two statements are true regarding the following extended ACL? (Choose two.) access-list 101 deny tcp 172.16.3.0 0.0.0.255 any eq 20 access-list 101 deny tcp 172.16.3.0 0.0.0.255 any eq 21 access-list 101 permit ip any any FTP traffic originating from network 172.16.3.0/24 is denied. All traffic is implicitly denied. FTP traffic destined for the 172.16.3.0/24 network is denied. Telnet traffic originating on network 172.16.3.0/24 is denied. Web traffic originating from 172.16.3.0 is permitted.

What characteristic in a routing protocol allows it to support the network design criteria for availability? CIDR support fast convergence timed updates VLSM support

What is a primary function of a wireless LAN controller? tuning each AP channel for optimal coverage providing PoE to the wireless clients distributing VLAN information to the wireless clients serving as the point of connection between wireless clients and the wired LAN
