Question No.291
Refer to the exhibit. Which two possible network conditions can you infer from this configuration? (Choose two.)
-
The authentication parameters on R1 and R2 are mismatched.
-
R1 is using the default NTP source configuration.
-
R1 and R2 have established an NTP session.
-
R2 is configured as the NTP master with a stratum of 7.
Correct Answer: AB
Explanation:
Answer A: The NTP associations are not synced, it is only listed as a candidate because it was configured. Routing is not the issue, so it must be mismatched authentication parameters.
Answer B: NTP sets the source IP address for all NTP packets based on the address of the interface through which the NTP packets are sent. You can configure NTP to use a specific source IP address.
Question No.292
Which statement is true about LLDP?
-
LLDP provides VTP support.
-
LLDP does not use a multicast address to communicate.
-
LLDP can indicate only the duplex setting of a link, and not the speed capabilities.
-
LLDP does not support native VLAN indication.
Correct Answer: D
Explanation:

Question No.293
Refer to the exhibit. You must complete the configuration on R1 so that a maximum of three links can be used and fragmentation is supported. Which additional configuration accomplishes this task?
-

interface Multilink19
ip address 192.168.1.1 255.255.255.252
ppp multilink
ppp multilink group 19
ppp multilink links maximum 3 ppp multilink interleave
Correct Answer: A
Explanation:
The quot;ppp multilink interleavequot; command is needed to enable link fragmentation and Interleaving (LFI). The Cisco IOS Link Fragmentation and Interleaving (LFI) feature uses Multilink PPP (MLP). MLP provides a method of splitting, recombining, and sequencing datagrams across multiple logical data links. MLP allows packets to be fragmented and the fragments to be sent at the same time over multiple point-to-point links to the same remote address.
ppp multilink links maximum
To limit the maximum number of links that Multilink PPP (MLP) can dial for dynamic allocation, use the ppp multilink links maximum command in interface configuration mode.

Question No.294
Refer to the exhibit. What will be the IP MTU of tunnel 0?
A.
1500
B.
1524
C.
1476
D.
1452
E.
1548
Correct Answer: C
Explanation:
In the case of the GRE tunnel interface, the IP maximum transmission unit (MTU) is 24 bytes less than the IP MTU of the real outgoing interface. For an Ethernet outgoing interface that means the IP MTU on the tunnel interface would be 1500 minus 24, or 1476 bytes.

Question No.295
Which technology facilitates neighbor IP address resolution in DMVPN?
-
CEF
-
mGRE
-
a dynamic routing protocol
-
NHRP
-
Correct Answer: D
Explanation:
NHRP Used with a DMVPN
NHRP is used to facilitate building a VPN and provides address resolution in DMVPN. In this
context, a VPN consists of a virtual Layer 3 network that is built on top of an actual Layer 3 network. The topology you use over the VPN is largely independent of the underlying network, and the protocols you run over it are completely independent of it. The VPN network (DMVPN) is based on GRE IP logical tunnels that can be protected by adding in IPsec to encrypt the GRE IP tunnels.

Question No.296
DRAG DROP
Correct Answer:
Question No.297
Refer to the exhibit. Which action must you take to enable full reachability from router C to router D?
-
Build an OSPF virtual link.
-
Build an OSPF sham link.
-
Configure mutual redistribution between OSPF and EIGRP on routers A and B.
-
Add a static route on router D.
Correct Answer: C
Explanation:
For full connectivity, we need to configure mutual redistribution to advertise the EIGRP routes into OSPF and to advertise the OSPF routes into the EIGRP network. This needs to be done at the two border routers that connect to both the EIGRP and OSPF domains.
Question No.298
DRAG DROP

Question No.299
Which two options are required parts of an EEM policy? (Choose two.)
-
event register keyword
-
body
-
environment must defines
-
namespace import
-
entry status
-
exit status
Correct Answer: AB
Explanation:
EEM policies require two parts: the event register keyword and the body. The remaining parts of the policy are optional: environment must defines, namespace import, entry status, and exit status (Figure 5).
