This webdemo is just a demo data, only for reference and learning, there is no other purposes.
1. A customer would like their remote users to be able to establish a
VPN tunnel with an alternate VPN Router, if the primary VPN Router
fails.
What would need to be configured to ensure Fail-over protection?
A. Demand Services
B. Firewall and DHCP settings on the remote PC
C. Only LDAP group parameters
D. VPN Router user tunnel for IPSec fail-over service
Answer: D
2.Virtual Router Redundancy Protocol (VRRP) has been configured on the
VPN Routers of a customer's network. However, all of the traffic is
being routed to the Backup and not the Master. What could be a possible
reason for this problem?
A. The Virtual Router ID (VRID) is not configured correctly.
B. The Backup and Master VPN Routers are running two different versions
of code.
C. The Priority Value of the Master is set to 100, and the Backup is set
to a higher value.
D. The authentication string in the Authentication Data field is not
set.
Answer: C
3. Virtual Router Redundancy Protocol (VRRP) has been configured to run
as master on a physical interface of a VPN Router. Two additional
interface groups have been associated with this master VRRP interface by
use of an interface group. Assume these two additional interface
groups have gone down. Which statement describes the state of the VRRP
master interface in this scenario?
A. The VRRP master interface remains in the up state as long as the
master physical interface is up.
B. The VRRP master interface stays in the down state until all
associated interface groups come up.
C. The VRRP master interface goes into a hold state until at least one
of the two interface groups comes up.
D. The VRRP master interface goes into a down state until at least one
of the two interface groups comes up.
Answer: B
4. Virtual Router Redundancy Protocol (VRRP) has been configured to run
as master on a physical interface of a VPN Router. Three additional
interfaces, each in a separate interface group, have been associated
with this master VRRP interface. Assume one of the three additional
interface has gone down. How will the VPN Router react?
A. It will force a VRRP fail-over.
B. It will reroute traffic to the associated VRRP master interface.
C. It will reroute traffic to one of the two remaining additional
interface groups.
D. No action necessary, since two additional interfaces are available to
the master.
Answer: A
5. To enable Fail-over support in a VPN Router configuration, a
technician is setting up Static Tunnel Fail-over for Branch Office
Tunnels. Primary and subsequent static routes will be created. To
provide the required Fail-over support, how will the primary tunnel be
configured?
A. It must be nailed up.
B. It must use RIP only.
C. It must use OSPF only.
D. It must be a virtual tunnel.
Answer: A
6. Employees at the company headquarters and out in the field have found
that they are moving from an Ethernet connection to a wireless
connection and back, on a regular basis while still having a VPN tunnel
established. A network administrator has been tasked with finding a
solution that preserves the IPSec tunnel while roaming within the LAN,
without affecting applications that use the VPN tunnel. Which solution
would you recommend for this customer?
A. IPSec fail-over
B. Nortel IPSec Mobility
C. Tunnel Persistance Mode
D. Virtual Router Redundancy Protocol (VRRP)
Answer: B
7. In a VPN Router network, a technician has enabled the Fail-over
feature so that all remote users working offsite using the Nortel VPN
Client will attempt to connect to one or more alternate VPN Router
devices if the primary VPN Router fails. Which statement is true
regarding the IP addresses specified for the alternate VPN Router
devices in the Fail-over?
A. The IP addresses must be for public interfaces.
B. The IP addresses must be for private interfaces.
C. The IP addresses must match the VPN Router management interface
address.
D. The IP addresses must match the primary VPN Router interface address.
Answer: A
8. A customer needs to provide fail-over support capability on their
statically routed branch office tunnels and would like to configure the
VPN Routers with redundant static routes. Which step can be used to
configure static tunnels for fail-over?
A. Create a single static tunnel.
B. Give subsequent static routes a lower cost.
C. Configure static tunnel fail-over using keep-alive and/or idle time
out.
D. Give the primary static route a higher cost.
Answer: C
