Which two protocols are used by a P router to transfer VPN traffic between PE routers in an MPLS network? (Choose two.)
- A . BGP
- B . OSPF
- C . MP-BGP
- D . LDP
- E . RSVP
Refer to the exhibit.
An engineer configures a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen.
What is the reason for this?
- A . Dynamic routing protocols always have priority over static routes.
- B . The metric of the OSPF route is lower than the metric of the static route.
- C . The configured AD for the static route is higher than the AD of OSPF.
- D . The syntax of the static route is not valid, so the route is not considered.
C
Explanation:
The AD of static route is manually configured to 130 which is higher than the AD of OSPF router which is 110.
Refer to the exhibit.
An administrator that is connected to the console does not see debug messages when remote users log in.
Which action ensures that debug messages are displayed for remote logins?
- A . Enter the transport input ssh configuration command.
- B . Enter the terminal monitor exec command.
- C . Enter the logging console debugging configuration command.
- D . Enter the aaa new-model configuration command.
C
Explanation:
The Dlogging console‖ is a default and hidden command.
Refer to the exhibit.
An engineer is investigating an OSPF issue reported by the Cisco DNA Assurance Center.
Which action resolves the issue?
- A . One of the neighbor links is down Bring the interface up by running shut and no shut
- B . One of the interfaces is using the wrong MTU Match interface MTU on both links
- C . An ACL entry blocking multicast on the interfaces Allow multicast through the interface ACL
- D . One of the interfaces is using the wrong authentication Match interface authentication on both links
SIMULATION
A DMVPN network is preconfigured with tunnel 0 IP address 192.168.1.254 on the HUB, IP connectivity, crypto policies, profiles, and EIGRP AS 100. The NHRP password is ccnp123, and the network ID and tunnel key is EIGRP ASN Do not introduce a static route.
Configure DMVPN connectivity between routers BR1 and BR2 to the HUB router using physical interface as the tunnel source to achieve these goals:
ON BR2
Which rouler takes an active role between two LDP neighbors when initiating LDP session negotiation and LDP TCP connection establishment?
- A . with the higher IP address
- B . with the larger number of LDP TCP neighbors
- C . with the lowest IP address
- D . with one interface in the MPLS backbone
Refer to the exhibit.
R1 is directly connected to R2 over network 10.100.14.0/24. An engineer configures R1 to advertise a static route that is connected to a local loopback for network 10.100.13.0/24. The network is not in the routing table of R2.
Which action resolves the issue?
- A . The redistribution command is incorrect on R1 The default metric metric 200 should be inducted
with the redistribution command. - B . The Loopback interface on R1 is administratively down. The interface should be enabled with the no shutdown command
- C . R2 must use a different OSPF process number and should be changed lo ospf 1 to match R1
- D . The redistribution command is incorrect on R1 The keyword subnets should be included with the redistribution command
Which IGPs are supported by the MPLS LDP autoconfiguration feature?
- A . RIPv2 and OSPF
- B . OSPF and EIGRP
- C . OSPF and ISIS
- D . ISIS and RIPv2
C
Explanation:
Refer to the exhibit.
AAA server 10.1.1.1 is configured with the default authentication and accounting settings, but the switch cannot communicate with the server.
Which action resolves this issue?
- A . Match the authentication port
- B . Match the accounting port
- C . Correct the timeout value.
- D . Correct the shared secret.
A
Explanation:
Command Default
Accounting port: 1813
Authentication port: 1812
Accounting: enabled
Authentication: enabled
Retransmission count: 1
Idle-time: 0
Server monitoring: disabled
Timeout: 5 seconds
Test username: test
Test password: test
Reference: https://www.cisco.com/c/m/en_us/techdoc/dc/reference/cli/n5k/commands/radius-server-host.html
By default, RADIUS uses UDP port 1812 for authentication and port 1813 for accounting. In the exhibit above we see port 1814 is being used for authentication to AAA server at 10.1.1.1 which is not the default port so we must adjust the authentication port to the default value 1812.
How many labels are present in an MPLS Layer 3 packet traversing through the network without traffic engineering?
- A . 1
- B . 2
- C . 3
- D . 4
