Answer: A,B
Q352. Which IPv6 prefix is used for 6to4 tunnel addresses?
A. 2001::/23
B. 2002::/16
C. 3ffe::/16
D. 5f00::/8
E. 2001::/32
Answer: B
Explanation:
6to4 works by taking advantage of a reserved IPv6 prefix, 2002::/16. A 6to4 tunnel interface automatically converts the 32 bits in its IPv6 address following this prefix to a global unicast IPv4 address for transport across an IPv4 network such as the public Internet.

Q353. Refer to the exhibit.
If the remaining configuration uses default values, what is the expected output of the show mls qos queue-set command?
A)
B)
C)
D)
A. Exhibit A
B. Exhibit B
C. Exhibit C
D. Exhibit D
Answer: A
Explanation:
mls qos queue-set output qset-idthreshold queue-id drop-threshold1 drop-threshold2 reserved-threshold maximum-threshold
Configure the WTD thresholds, guarantee the availability of buffers, and configure the maximum memory allocation for the queue-set (four egress queues per port).
By default, the WTD thresholds for queues 1, 3, and 4 are set to 100 percent. The thresholds for queue 2 are set to 200 percent. The reserved thresholds for queues 1, 2, 3,
and 4 are set to 50 percent. The maximum thresholds for all queues are set to 400 percent.
. For qset-id , enter the ID of the queue-set specified in Step 2. The range is 1 to 2.
. For queue-id , enter the specific queue in the queue-set on which the command is performed. The range is 1 to 4.
. For drop-threshold1 drop-threshold2 , specify the two WTD thresholds expressed as a percentage of the queue’s allocated memory. Th e range is 1 to 3200 percent.
. For reserved-threshold , enter the amount of memory to be guaranteed (reserved) for the queue expressed as a percentage of the allocated memory. The range is 1 to 100 percent.
. For maximum-threshold , enable a queue in the full condition to obtain more buffers than are reserved for it. This is the maximum memory the queue can have before the packets are dropped if the common pool is not empty. The range is 1 to 3200 percent

Q356. Which IP SLA operation type is enhanced by the use of the IP SLAs Responder?
A. DNS
B. HTTP
C. ICMP Echo
D. UDP Echo
Answer: D
Explanation:
Figure 1. UDP Echo Operation
Response time (round-trip time) is computed by measuring the time taken between sending a UDP echo request message from Device B to the destination device--Device A--and receiving a UDP echo reply from Device A. UDP echo accuracy is enhanced by using the IP SLAs Responder at Device A, the destination Cisco device. If the destination device is a Cisco device, then IP SLAs sends a UDP datagram to any port number that you specified. Using the IP SLAs Responder is optional for a UDP echo operation when using Cisco devices. The IP SLAs Responder cannot be configured on non-Cisco devices.

Q358. Refer to the exhibit.
Which statement about this GETVPN configuration is true?
A. Co-operative key servers are configured.
B. Redundant peers are configured.
C. The key server uses multicast mode to propagate rekey messages.
D. PSK authentication is configured.
Answer: A
Q359. Which statement is true about MLD?
A. MLD v1 gives hosts the ability to receive multicast packets from specific source addresses.
B. All MLD messages are sent with a link-local IPv6 source address of FF02::D.
C. The multicast address field is cleared to zero when sending an MLD report message.
D. MLD is used by IPv6 routers to discover multicast listeners on a directly attached link.
Answer: D
Explanation:
IPv6 Multicast Listener Discovery (MLD) is used by IPv6 devices to discover multicast listeners (nodes that want to receive multicast packets destined for specific multicast addresses) on directly attached links. There are two versions of MLD. MLD version 1 is based on version 2 of the IGMP for IPv4, and MLD version 2 is based on version 3 of the IGMP for IPv4. IPv6 multicast for Cisco software uses both MLD version 2 and MLD version 1.
