300-410 VOL1 Flashcards
You have configured router R1 with multiple VRF’s in order to support multiple customer VPN
networks. If you wanted to see the best path for the 10.1.1.0.24 route in VRF Blue, what
command would you use?
A. show ip route vrf Blue 10.1.1.0
Which of the following OSPF Link State Advertisements (LSA’s) were created for IPV6 and do not
apply to IPv4 OSPF networks? (Select two)
A. Link LSA (Type 8)
D. Intra-Area Prefix LSA (Type 9)
You want to redistribute this route into OSPF but when you configure the redistribute static
command under the OSPF process the default route is not present. What will create a default
route in the OSPF routing process?
C. Use the default-information originate command under the OSPF process.
Which one of the following statements regarding Bidirectional Forwarding Detection (BFD) is
correct?
A. BFD echo mode is the default mode of operation.
Which of the following OSPF neighbor adjacency states is applicable only to manually configured
OSPF neighbors in a Non-Broadcast Multi-Access network?
A. Attempt
With Internal BGP, there is a requirement for all peers to be logically fully meshed, where all IBGP
routers must peer with all other IBGP routers. For scaling purposes, there are two mechanisms
that were developed to bypass this requirement. What are they?
A. Confederations
D. Route reflectors.
You have configured policy-based routing on router R1 to force some traffic to go over an
alternate link. In order to verify the configuration, which debug command should be used to
verify that the specific traffic is taking the intended path?
C. Debug ip policy
Which BGP attribute can be used to influence the path that incoming traffic takes into your AS
from other Autonomous Systems?
A. Metric man
B. AS_Path
Routers R1 and R2 have been configured to use Bidirectional Forwarding Detection. What is the
advantage of doing this?
D. It is able to discover local link failures at layers 1 and 2 and provides detection for this in
less than one second.
Which BGP attribute can be used to influence the path that outgoing traffic takes from your AS
to other Autonomous Systems? (Select two)
C. Weight
D. Local Preference
In order to connect disparate OSPF and EIGRP portions of a network, mutual route
redistribution has been configured. What are the two disadvantages of doing this?
A. Prone to routing loops if not done correctly
B. Differing metrics between the routing protocols could result in sub-optimal routing.
Which of the following statements are true regarding two EIGRP routers to become neighbors?
D. Must use the same ASN.
Which of the following statements are true regarding two OSPF routers becoming neighbors?
(Select two)
A. Must use the same ASN
C. Must have matching MTU’s on the physical network links that connect the routers.
A new site has been added to an OPSF network using Area 2. Area 2 is connected only to Area 1
of this OSPF network. Area 1 is used to connect area 1 to the backbone area 0. Should you expect
full connectivity to the networks located in Area 2 from Area 0 in this scenario?
C. No, a virtual link is needed to logically connect Area 2 to Area 0.
Router R1 is configured using VRFs to support customer VPNs. Some customers are using the
same private IP address space. Which of the following is used to ensure that these routes are
unique when advertised throughout the VPN?
A. Route Distinguisher
