You are troubleshooting an OSPF adjacency problem between R1 and R2. 

Referring to the exhibit, what is causing this OSPF adjacency problem? 

A. There is a hello interval mismatch. 

B. There is a dead interval mismatch. 

C. There is an MTU mismatch. 

D. There is an LSA refresh timer mismatch. 

Answer:


Q13. You are implementing Q-in-Q tunneling on an EX Series switch. You want the tunnel to support all C-VLANs; however, only some VLANs are able to send traffic across the tunnel. Switch-1 has the following configuration: 

[edit vlans] 

user@Switch-1# show 

v100 { 

vlan-id 100; 

interface { 

ge-0/0/0.10; 

ge-0/0/1.20; 

dot1q-tunneling { 

customer-vlans [ ]; 

What would solve this problem? 

A. Add family ethernet-switching to the tunnel-side interface on Switch-1. 

B. Implement RSTP. 

C. Q-in-Q tunneling will not work in this scenario; use a Layer 2 VPN instead. 

D. Remove the customer-vlans statement.

Click the Exhibit button. 

You are troubleshooting a problem where an EBGP route is not being advertised to your local IBGP peers. You have received a 10.222.1.3/32 route from an EBGP peer as shown in the exhibit, but the route is not being advertised. 

What is causing the problem? 

A. The route shows as a hidden route and cannot be advertised. 

B. The next hop for the route is indirect and prevents the route from being advertised. 

C. The community prevents the route from being advertised. 

D. The local preference value is too high for the route to be advertised. 

Answer:


Q15. Your Layer 2 network uses VLAN IDs 100 through 400 and you are required to load-balance these VLANs between two different root bridges. You are currently using the default RSTP settings and notice that all VLANs are using the same root bridge. 

How do you ensure the VLANs are load-balanced between two root bridges? 

A. Configure MSTP with two MSTI regions and split the VLAN range between them. 

B. Configure VSTP with two VLAN groups and split the VLAN range between them. 

C. Configure two RSTP instances and split the VLAN range between them. 

D. Configure STP and RSTP and split the VLAN range between them.

Traffic with the IP precedence value af21 ingresses the router and should be rewritten with the same value as it egresses; however, this traffic is rewritten to a different value. 

Referring to the exhibit, what is the source of this problem? 

A. The BA classifier is assigning the traffic to the best-effort queue with a high loss priority. 

B. The BA classifier is assigning the traffic to the best-effort queue with a low loss priority. 

C. The BA classifier is assigning the traffic to the expedited forwarding queue with a high loss priority. 

D. The BA classifier is assigning the traffic to the expedited forwarding queue with a low loss priority.

Referring to the exhibit, you are configuring an OSPF network. All OSPF adjacencies come up and stay stable. But neither R1 nor R2 has the prefix 200.200.200.200/32 in its routing table. 

What is causing this problem? 

A. R2 does not have the export policy for prefix 200.200.200.200/32. 

B. R1 does not have routes to network 172.10.1.0/24. 

C. R2 is BDR on both network 172.10.1.0/24 and 172.20.1.0/24. 

D. The router ID of R1 is the same as the router ID of R3.

Q18. Your switch is experiencing a problem where a port that should have only one host connected occasionally shows that multiple MAC addresses are being learned. 

Which configuration setting would ensure that no extra hosts can join the network using this switch port? 

A. mac-limit 

B. no-mac-learning 

C. persistent-learning 

D. bpdu-block-on-edge 

Answer:


Q19. You recently deployed two Anycast RPs. Multicast clients in the network are reporting that they are receiving traffic from some, but not all, multicast sources. 

What are two solutions for this problem? (Choose two.) 

A. Configure MSDP between the Anycast RPs. 

B. Configure rp-set for the Anycast RPs. 

C. Configure multicast BGP between the Anycast RPs. 

D. Configure the network to always use the RPT and not switch over to the SPT. 

Answer: A,B
