Cisco 300-320 Free Practice Questions

Q1. Which option prevents the dropping of asymmetrically routed packets in active/active failover paired firewalls? 

A. Nothing can be done to prevent this from happening. 

B. Configure different policies on both firewalls. 

C. Assign similar interfaces on each firewall to the same asymmetric routing group. 

D. Assign similar interfaces on each firewall to a different asymmetric routing group. 

Answer:

Q2. Which option is a method of restricting access for users based on user roles and locales? A. RBAC 

B. ACE 

C. LDAP 

D. RADIUS 

Answer:

Q3. Support of vPC on the Cisco Nexus 5000 access switch enables various new design options for the data center Access layer, including which of the following? 

A. The vPC peer link is not required for Access layer control traffic, and can instead be used to span VLANs across the vPC access switches 

B. A single switch can associate per-interface with more than one vPC domain 

C. vPC can be used on both sides of the MEC, allowing a unique 16-link EtherChannel to be built between the access and aggregation switches 

D. Allows an EtherChannel between a server and a access switch while still maintaining the level of availability that is associated with dual-homing a server to two different access switches 

Answer:

Q4. Refer to the exhibit. 

Which recommended practice is applicable? 

A. If no core layer is deployed, the design will be easier to scale. 

B. A dedicated campus core layer should be deployed for connecting three or more buildings. 

C. If no core layer is deployed, the distribution switches should not be fully meshed. 

D. A dedicated campus core layer is not needed for connecting fewer than five buildings. 

Answer:

Q5. Two recently merged companies are using EIGRP and RIP. Which two strategies can facilitate a smooth migration? (Choose two.) 

A. Create an OSPF instance between EIGRP and RIP routing domains. 

B. Redistribute routing information between the RIP and EIGRP protocols. 

C. Add EIGRP and then remove RIP on the acquired company network. 

D. Use the EIGRP administrative distance to migrate one site at a time. 

E. Use static routes in place of dynamic routing between companies. 

Answer: B,C 

Q6. Which three statements about firewall modes are correct? (Choose three.) 

A. A firewall in routed mode has one IP address. 

B. A firewall in transparent mode has one IP address. 

C. In routed mode, the firewall is considered to be a Layer 2 device. 

D. In routed mode, the firewall is considered to be a Layer 3 device. 

E. In transparent mode, the firewall is considered to be a Layer 2 device. 

F. In transparent mode, the firewall is considered to be a Layer 3 device. 

Answer: B,D,E 

Q7. Recently, the WAN links between the headquarters and branch offices have been slow under peak congestion, yet multiple alternate WAN paths exist that are not always congested. What technology can allow traffic to be routed in a more informed manner to utilize transport characteristics such as delay, loss, or link load? 

A. performance routing 

B. static routing 

C. on demand routing 

D. policy based routing 

Answer:

Q8. Which protocol should be configured if a network administrator has the following requirements? 

. Multiple physical gateways participating simultaneously in packet forwarding. 

. All hosts in the VLAN configured with the same default gateway address. 

A. HSRP 

B. VRRP 

C. VTP 

D. GLBP 

Answer:

Q9. A VPN solution requires bulk traffic encryption, low OpEx to add new sites, and the ability to accommodate dynamic tunnels between branch locations. What VPN solution can fulfill these requirements? 

A. GETVPN 

B. SSL VPN 

C. Easy VPN 

D. DMVPN 

Answer:

Q10. What are two advantages of using Cisco FEX devices in the data center design? (Choose two.) 

A. Traffic-forwarding decisions are made by the Cisco FEX device. 

B. Cisco FEX devices must be upgraded when the parent switch is upgraded. 

C. Traffic-forwarding decisions are made by the parent switch, resulting in easier troubleshooting and centralized management. 

D. Cisco FEX devices do not have to be upgraded when the parent switch is upgraded, resulting in cost savings. 

E. Cisco FEX devices can be part of two different VDCs. 

Answer: C,D
