Acme Corporation indicates that their network design must support the ability to scale to support a high
number of remote sites. Which IGP is considered to scale better for a hub-and-spoke topology?
A. BGP
B. OSPF
C. IS-IS
D. EIGRP

A junior engineer is implementing one of your optical designs and asks about CWDM (Coarse Wavelength
Division Multiplexing). Which two features describe CWDM? (Choose two.)
A. typically used over long distances, but requires optical amplification
B. allows up to 32 optical carriers to be multiplexed onto a single fiber
C. shares the same transmission window as DWDM
D. uses the 850-nm band
E. Passive CWDM devices require no electrical power.

A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane. How
will they adjust the design to reduce the flooding of update packets?
A. Change the area type of the links to be level-1-2 to allow level-1 updates.
B. Change the network type of the links from broadcast to point-to-point.
C. Use IS-IS mesh groups.
D. Configure SPF timers to be more aggressive so that updates are more quickly cleared from the queue.

You have been asked to design a wireless network solution that will implement context-aware serviceson an
existing network that was initially deployed for data traffic only. Which two design principles would you follow
to increase the location accuracy with the least possible impact on the current setup? (Choose two.)
A. Use directional antennas to provide better cell separation.
B. Add access points along the perimeter of the coverage area.
C. Install additional APs in monitor mode where the cochannel interference would otherwise be affected.
D. Increase the AP density to create an average interaccess point distance of less than 40 ft.
E. Fine tune the access points radio configuration to have a higher average transmission power to achieve
better coverage.

You have been asked to establish a design that will allow your company to migrate from a WAN serviceto a
Layer 3 VPN service. In your design, you are keeping some WAN links between critical sites as a backup for
this service. You plan to use OSPF as your IGP and BGP for the PE- CE protocol. When the Layer 3 VPN
service is available, how will you prevent transit traffic over the backup links?
A. Redistribute routes at the CE as external type 1.
B. Redistribute routes at the CE as external type 2.
C. Use conditional advertisement only when the Layer 3 service is down.
D. Manually turn off the backdoor link when the Layer 3 service is up.

You are designing an 802.11 wireless network to include a controller as a central configuration point and
access points across several remote sites. Which two aspects will manage the flow of the traffic to meet these
design considerations? (Choose two.)
A. WLAN local switching with VLAN mapping requires that VLAN ID that is mapped on the AP to match a
dynamic interface that is configured on the wireless LAN controller.
B. Layer 3 roaming is not supported for locally switched WLANs.
C. The 802.1x authentication for a client associated to an AP on a locally switched WLAN is always handled
at the wireless LAN controller side.
D. The access point can receive multicast traffic in the form of multicast packets from the WLC.
E. WLAN access lists can be applied only to centrally switched WLANs.

When a multiprotocol environment is designed to have several routers redistribute among the routing
domains, how can routing loops be avoided?
A. by using the AS-PATH attribute
B. by using route tags
C. by activating split horizon
D. by implementing spanning tree

You are designing a NAC OOB Layer 3 Real-IP Gateway deployment for a customer. Which VLAN must be
trunked back to the Clean Access Server from the access switch?
A. untrusted VLAN
B. user VLAN
C. management VLAN
D. authentication VLAN

You have designed a network to support two offices connected by a T1. Your router serial interfaces will be
configured with encapsulation PPP. What will happen to your EIGRP neighbors if there is an LCP failure once
your network is implemented?
A. Your neighbors will drop after the EIGRP timers expire.
B. Your neighbors will stay up because the link has not gone down.
C. Your neighbors will drop immediately.
D. Your neighbors will drop and EIGRP will begin the query process.

Your firm has been awarded a contract to design a Criminal Justice Information Services Version 5.0-compliant network utilizing advanced authentication policies. Which two methods could be utilized? (Choose
two.)
A. biometric
B. PKI
C. UKI
D. password
