1.

What is the recommended practice when considering VPN termination and firewall placement?

have the firewall and VPN appliance deployed in parallel place the VPN in line with the firewall, with the VPN terminating inside the firewall place the public side of the VPN termination device in the DMZ behind a firewall place the VPN in line with the firewall, with the VPN terminating outside the firewall

2.

What will an Easy VPN hardware client require in order to insert its protected network address when it connects using network extension mode?

RADIUS or LDAP an internal router running EIGRP Reverse Route Injection and OSPF or RIPv2 the VPN appliance to be deployed in line with the firewall

3.

Which two of these are advantages of placing the VPN device in the DMZ on the firewall? (Choose
two.)

fewer devices to manage moderate-to-high scalability stateful inspection of decrypted VPN traffic increased bandwidth with additional interfaces decreased complexity as traffic is filtered from the firewall

4.

What is the primary issue when scaling VPNs?

number of tunnels number of remote sites packets per second throughput bandwidth

5.

Which of these statements is true of routing protocols in a hub-and-spoke IPsec VPN topology?

EIGRP can summarize per interface. OSPF router databases remain independent. When they are configured with stubs, EIGRP regularly floods the topology. OSPF topology decisions are made independent of hierarchy or area.

6.

Which statement correctly describes a situation in which VRFs are used in the data center?

Partitioning of network resources is enabled. VRFs cannot support path isolation from MAN/WAN designs. VRFs cannot be used to map a virtualized data center to a MPLS implementation. VRFs do not allow for the use of application services with multiple access topologies. An access design using a VRF allows for an aggregation layer service module solution.

7.

You are the network consultant from Cisco.com. Please point out which Layer 2 access designs does not support VLAN extensions?

FlexLinks loop-free U looped square looped triangle

8.

You are the Cisco Network Designer in Cisco.com. Which of these is a Layer 2 transport architecture that provides packet-based transmission optimized for data based on a dual ring topology?

Dynamic Trunking Protocol Resilient Packet Ring Synchronous Digital Hierarchy Coarse Wave Division Multiplexing

9.

Which of these is a Layer 2 transport architecture that provides packet-based transmission optimized for data based on a dual (counter-rotating) ring topology?

DTP RPR SDH CWDM DWDM

10.

Which of these terms refers to call issues that cause variations in timing or time of arrival?

Queuing Jitter Packet loss Digitized sampling Signal-to-noise ratio ratio
