1.

After properly configuring multiple VLANs, an administrator has decided to secure its VLAN network. Which three steps are required to secure this environment? (Choose three)

If a port is connected to a foreign device make sure to disable CDP, DTP, RPR, PAgP, UDLP, and any other unnecessary protocols, and enable UplinkFast/BPDU guard on it. Disable all unused ports and place them in an unused VLAN to avoid unauthorizedaccess Configure VTP domains appropriately or turn off VTP altogether to limit or preventundesirable protocol interaction with regards to the network-wide VLAN configuration Enable root guard feature to prevent a directly or indirectly connected STP-capabledevice from affecting the location of the root bridge Set the native VLAN ID to match the port VLAN ID of any 802.1q trunk to preventspoofing

2.

When should you run multiple protocols?

when you migrate from an old IGP to a new IGP when you want to decrease the complexity of the network when you want higher efficiency when you want easier optimization

3.

How can you mitigate threats in WLANS when static WEP keys are used?

Provide different keys to the client and the access point Assign matching keys to the client and the access point Use SSID to provide security Use standard 802.11 WEP keys, which are very secure

4.

Which of these is a benefit of an integrated security management system?

It provides a single point of contact for all security configuration tasks thereby enhancing the return on investment It provides configuration, monitoring, and troubleshooting capabilities across a widerange of security products It integrates security device management products and collects events on an as neededbasis to reduce management overhead It integrates security management capabilities into the router or switch It leverages existing network management systems such as HP OpenView to lower thecost of implementation

5.

What should you keep in mind when using a firewall to secure traffic?

Simple stateful firewalls are much slower than Proxy firewalls Hybrid firewalls do not provide complete session termination Proxy firewalls permit traffic to pass directly between networks Proxy firewalls are faster than other technologies

6.

What is used to dynamically create a pair or multiple pairs of sources addresses?

IKE ESP ISAKMP AH

7.

What is a characteristic of a classful network environment?

Different subnets within the same major network must have the same subnet mask The subnet mask is exchanged during the routing update process The route summarization process cannot be controlled manually The network automatically summarizes the network mask at major networkboundaries

8.

What should you keep in mind when using a midspan PSE?

What should you keep in mind when using a midspan PSE? It can implement power delivery only over the spare wires of the copper cabling It defines terminology to describe a port that acts as a PSE to a powered device It states that power can be delivered by an end-point PSE

9.

Which statement concerning the Active/Active failover feature is correct?

Active/Active failover supports site-to-site IPSec VPN stateful failover If an active security context within the primary security appliance fails, the status ofthe primary security appliance unit changes to failed , while the secondary failover security appliance unit transitions to active Active/Active failover is supported in multiple mode configuration only ASA security Appliance failover pair must have either an Unrestricted and UR licenseor a UR and FO-A/A license to be able to support Active/Active failover

10.

How does the Cisco Small Business Pro Service differ from the Cisco Small Business Pro Warranty?

Access to Cisco Small Business Support Community speed of hardware replacement Cisco Small Business Pro products only device-level warranty
