NEW QUESTION 18
Drag and drop the LISP components from the left onto the function they perform on the right. Not all options are used.
Answer:
Explanation:
Explanation
+ accepts LISP encapsulated map requests: LISP map resolver
+ learns of EID prefix mapping entries from an ETR: LISP map server
+ receives traffic from LISP sites and sends it to non-LISP sites: LISP proxy ETR
+ receives packets from site-facing interfaces: LISP ITR
Explanation
ITR is the function that maps the destination EID to a destination RLOC and then encapsulates the original packet with an additional header that has the source IP address of the ITR RLOC and the destination IP address of the RLOC of an Egress Tunnel Router (ETR).
After the encapsulation, the original packet become a LISP packet.
ETR is the function that receives LISP encapsulated packets, decapsulates them and forwards to its local EIDs. This function also requires EID-to-RLOC mappings so we need to point out an "map-server" IP address and the key (password) for authentication.
A LISP proxy ETR (PETR) implements ETR functions on behalf of non-LISP sites. A PETR is typically used when a LISP site needs to send traffic to non-LISP sites but the LISP site is connected through a service provider that does not accept no routable EIDs as packet sources. PETRs act just like ETRs but for EIDs that send traffic to destinations at non-LISP sites.
Map Server (MS) processes the registration of authentication keys and EID-to-RLOC mappings. ETRs sends periodic Map-Register messages to all its configured Map Servers.
Map Resolver (MR): a LISP component which accepts LISP Encapsulated Map Requests, typically from an ITR, quickly determines whether or not the destination IP address is part of the EID namespace

What step resolves the authentication issue?
- A. restart the vsmart host
- B. use basic authentication
- C. change the port to 12446
- D. target 192 168 100 82 in the URI
Answer: D
Explanation:
he first figure is the output of the "show control connections" command. From this figure we learned that the 192.168.100.82 so we need to connect to this IP address (not 192.168.100.80).

NEW QUESTION 23
An engineer measures the Wi-Fi coverage at a customer site. The RSSI values are recorded as follows:
Which two statements does the engineer use to explain these values to the customer? (Choose two)
- A. The signal strength at location B is 10 dB better than location C
- B. The RF signal strength at location C is 10 times stronger than location B
- C. Location D has the strongest RF signal strength
- D. The RF signal strength at location B is 50% weaker than location A
- E. The signal strength at location C is too weak to support web surfing
Answer: B,E
Explanation:
Reference:
Understanding Signal Strength
The most accurate way to express it is with milliwatts (mW), but you end up with tons of decimal places due to WiFi's super-low transmit power, making it difficult to read. For example, -40 dBm is 0.0001 mW, and the zeros just get more intense the more the signal strength drops.
Ultimately, the easiest and most consistent way to express signal strength is with dBm, which stands for decibels relative to a milliwatt.
You can convert between mW and dBm using the following formulas:
P(dBm) = 10 * log10(P(mW))
For example, a power of 2.5 mW in dBm is:
dBm = 10log2.5 = 3.979
dBm is that we're working in negatives. -30 is a higher (stronger) signal than -80.
Signal Strength
Rating
Required for
-30 dBm
Amazing
Max achievable signal strength. The client can only be a few feet from the AP to achieve this. Not typical or desirable in the real world.
N/A
-67 dBm
Very Good
Minimum signal strength for applications that require very reliable, timely delivery of data packets.
VoIP/VoWiFi, streaming video
-70 dBm
Okay
Minimum signal strength for reliable packet delivery.
Email, web
-80 dBm
Not Good
Minimum signal strength for basic connectivity. Packet delivery may be unreliable.
N/A
-90 dBm
Unusable
Approaching or drowning in the noise floor. Any functionality is highly unlikely.
N/A
3 dB of gain = +3 dB = doubles signal strength (Let's say, the base is P. So 10*log10(P/P)= 0 dB and 10*log10(2P/P) = 10*log10(2) = 3dB -> double signal)
3 dB of loss = -3 dB = halves signal strength strength (10*log(1/2) = -3.0103)
10 dB of loss = -10 dB = 10 times less signal strength (0.1 mW = -10 dBm, 0.01 mW = -20 dBm, etc.)
10 dB of gain = +10 dB = 10 times more signal strength (0.00001 mW = -50 dBm, 0.0001 mW = -40 dBm, etc.)
Simple rule of thumb:
When working with power, 3 dB means double (twice) the factor and 10 dB means 10-fold.

NEW QUESTION 27
What mechanism does PIM use to forward multicast traffic?
- A. PIM sparse mode uses a flood and prune model to deliver multicast traffic.
- B. PIM sparse mode uses receivers to register with the RP.
- C. PIM sparse mode uses a pull model to deliver multicast traffic.
- D. PIM dense mode uses a pull model to deliver multicast traffic.
Answer: C
Explanation:
Reference:
PIM dense mode (PIM-DM) uses a push model to flood multicast traffic to every corner of the network. This push model is a brute-force method of delivering data to the receivers. This method would be efficient in certain deployments in which there are active receivers on every subnet in the network. PIM-DM initially floods multicast traffic throughout the network. Routers that have no downstream neighbors prune the unwanted traffic. This process repeats every 3 minutes.
PIM Sparse Mode (PIM-SM) uses a pull model to deliver multicast traffic. Only network segments with active receivers that have explicitly requested the data receive the traffic. PIM-SM distributes information about active sources by forwarding data packets on the shared tree. Because PIM-SM uses shared trees (at least initially), it requires the use of an RP. The RP must be administratively configured in the network.
Answer C seems to be correct but it is not, PIM spare mode uses sources (not receivers) to register with the RP. Sources register with the RP, and then data is forwarded down the shared tree to the receivers.
NEW QUESTION 28

NEW QUESTION 29
A GRE tunnel is down with the error message %TUN-5-RECUR DOWN:
Which two options describe possible causes of the error? (Choose two)
- A. Incorrect destination IP addresses are configured on the tunnel
- B. The tunnel mode and tunnel IP address are misconfigured
- C. There is link flapping on the tunnel
- D. The tunnel destination is being routed out of the tunnel interface
- E. There is instability in the network due to route flapping
Answer: D,E
Explanation:
Explanation
The %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing error message means that the generic routing encapsulation (GRE) tunnel router has discovered a recursive routing problem. This condition is usually due to one of these causes:
+ A misconfiguration that causes the router to try to route to the tunnel destination address using the tunnel interface itself (recursive routing)
+ A temporary instability caused by route flapping elsewhere in the network

NEW QUESTION 30
If a VRRP master router fails, which router is selected as the new master router?
- A. router with the highest priority
- B. router with the lowest priority
- C. router with the highest loopback address
- D. router with the lowest loopback address
Answer: A
NEW QUESTION 31
How does QoS traffic shaping alleviate network congestion?
- A. It drops packets randomly from lower priority queues.
- B. It fragments large packets and queues them for delivery.
- C. It buffers and queue packets above the committed rate.
- D. It drops packets when traffic exceeds a certain bitrate.
Answer: C
Explanation:
Explanation
Traffic shaping retains excess packets in a queue and then schedules the excess for later transmission over increments of time. The result of traffic shaping is a smoothed packet output rate.
