| Question 1 | You currently have a primary SE in slot 1. You've purchased a second SE. What slot or slots can you put this card in to provide redundancy with your SEs? |
| A1: | Answer A is correct. To provide redundancy SEs, the two SEs must be in slots 1 and 2. Therefore, answers B and C are incorrect. Answer D is incorrect because redundancy is supported. |
| Question 2 | You've configured RPR on your Catalyst 6500 switch. Which of the following does not cause a switchover? |
| A2: | Answer C is correct. RPR provides redundancy for the MSFC and PFC, not line cards. Answers A and B will cause a failover and are therefore incorrect. Because there is a correct answer, answer D is incorrect. |
| Question 3 | Which of the following uses ICMP to discover default gateways? A. Proxy ARP B. IRDP C. RIP D. DHCP
|
| A3: | Answer B is correct. IRDP allows RPs to announce themselves via ICMP multicast messages. A is incorrect because Proxy ARP has an RP pretend to be a destination on a different subnet, responding to an end-station's ARP request with the RP's MAC address. Answer C is incorrect because RIP is a routing protocol that uses UDP, not ICMP. DHCP uses BOOTP, making answer D incorrect. |
| Question 4 | If a default gateway fails and you're using IRDP, it can take up to __________ minutes to discover an alternative default gateway. |
| A4: | Answer D is correct. The hold-down timer for IRDP is typically 30 minutes, making answers A, B, and C incorrect. |
| Question 5 | Which of the following MAC addresses is an example of a MAC address used by HSRP group 10? A. 0000.0c07.ac10 B. 0000.0c07.ac0a C. 0000.aaaa.ac0a D. 0000.0c11.ac0a
|
| A5: | Answer B is correct. HSRP addresses begin with 0000.0c07.ac and are followed by the group number in hex. Answer A is incorrect because it represents 16 in decimal. Answers C and D are incorrect because they begin with the wrong MAC address value. |
| Question 6 | HSRP routers send out hellos every _________ seconds. |
| A6: | Answer B is correct. HSRP routers send out hellos every 3 seconds, by default. Therefore, answers A, C, and D are incorrect. |
| Question 7 | In which HSRP state does an election process occur? A. Listening B. Speaking C. Standby D. Initial
|
| A7: | Answer B is correct. Answer A is incorrect because RPs learn the virtual addresses in this state. Only the standby RP enters the state in answer C, making it an incorrect answer. In an initial state, the RP is not participating in HSRP yet, making answer D incorrect. |
| Question 8 | Which command enables HSRP on an RP? A. (config)# hsrp enable B. (config-if)# standby enable C. (config-if)# standby ip D. (config-if)# hsrp enable
|
| A8: | Answer C is correct. Use the standby ip command on an interface to enable HSRP. Answers A, B, and D are invalid commands, making them incorrect answers. |
| Question 9 | What type of redundancy can use either a virtual or real address for a default gateway? A. HSRP B. VRRP C. GLBP D. SLB
|
| A9: | Answer B is correct. VRRP can use either a virtual or real address of a default gateway when providing redundancy. Answers A and C are incorrect because only a virtual address can be used. SLB can use both sets of addresses, but only for load balancing to servers, not for default gateway redundancy, making answer D incorrect. |
| Question 10 | With GLBP, how many RPs in a group can forward traffic? |
| A10: | Answer C is correct. GLBP supports up to 4 AVFs in a group. Answer A would be true for HSRP, but false for GLBP. Answer B is not true. Answer D might be true if there were only four RPs in the VLAN, but the question asks for a group, making this answer false. |
