What is the JSON syntax that is formed the data?
- A. Name", "Bob Johnson", "Age", 76, "Alive", true, "favourite Foods", ["Cereal, "Mustard", Onions"}}
- B. {"Name":"Bob Johnson","age":76,"alive":true,"favorite
foods":["Cereal","Mustard","Onions"]}correct - C. Name", "Bob Johnson", "Age": Seventysix, "Alive" true, "favourite Foods" ,[Cereal" "Mustard"
"Onions"}} - D. Name', 'Bob Johnson,' 'Age', 76, 'Alive', true, 'favourite Foods' 'Cereal Mustard', 'Onions'}
- E. Name: Bob, Johnson, Age: 76, Alive: true, Favourite Foods. [Cereal, "Mustard", "Onions}}
Answer: B
Explanation:
Explanation
JSON data is written as name/value pairs.
A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value:
"name":"Mark"
JSON can use arrays. Array values must be of type string, number, object, array, boolean or null.
For example:
{
"name":"John",
"age":30,
"alive":true,
"cars":[ "Ford", "BMW", "Fiat" ]
}

NEW QUESTION 64
Drag and drop characteristics of PIM dense mode from the left to the right.
Answer:
Explanation:
Explanation
PIM-DM supports only source trees - that is, (S,G) entries-and cannot be used to build a shared distribution tree.
Reference:
https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipmulti_pim/configuration/xe-16-5/imc-pim-xe-16-5-book/im 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.
A rendezvous point (RP) is required only in networks running Protocol Independent Multicast sparse mode (PIM-SM).
In PIM dense mode (PIM-DM), multicast traffic is initially flooded to all segments of the network. Routers that have no downstream neighbors or directly connected receivers prune back the unwanted traffic.

NEW QUESTION 67
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
NEW QUESTION 68

NEW QUESTION 69
What is calculated using the numerical values of the transmitter power level, cable loss, and antenna gain?
- A. dBi
- B. EIRP
- C. RSSI
- D. SNR
Answer: B
Explanation:
Once you know the complete combination of transmitter power level, the length of cable, and the antenna gain, you can figure out the actual power level that will be radiated from the antenna. This is known as the effective isotropic radiated power (EIRP), measured in dBm.
EIRP is a very important parameter because it is regulated by governmental agencies in most countries. In those cases, a system cannot radiate signals higher than a maximum allowable EIRP. To find the EIRP of a system, simply add the transmitter power level to the antenna gain and subtract the cable loss.

- D. The device will allow only users at 192 168.0.202 to connect to vty lines 0 through 4
Answer: A
NEW QUESTION 71
Which NGFW mode block flows crossing the firewall?
- A. Inline
- B. Inline tap
- C. Tap
- D. Passive
Answer: A
Explanation:
Firepower Threat Defense (FTD) provides six interface modes which are: Routed, Switched, Inline Pair, Inline Pair with Tap, Passive, Passive (ERSPAN).
When Inline Pair Mode is in use, packets can be blocked since they are processed inline When you use Inline Pair mode, the packet goes mainly through the FTD Snort engine When Tap Mode is enabled, a copy of the packet is inspected and dropped internally while the actual traffic goes through FTD unmodified Reference:

NEW QUESTION 72
What are two device roles in Cisco SD-Access fabric? (Choose two.)
- A. edge node
- B. core switch
- C. access switch
- D. vBond controller
- E. border node
Answer: A,E
Explanation:
Explanation
There are five basic device roles in the fabric overlay:
+ Control plane node: This node contains the settings, protocols, and mapping tables to provide the endpoint-to-location (EID-to-RLOC) mapping system for the fabric overlay.
+ Fabric border node: This fabric device (for example, core layer device) connects external Layer 3 networks to the SDA fabric.
+ Fabric edge node: This fabric device (for example, access or distribution layer device) connects wired endpoints to the SDA fabric.
+ Fabric WLAN controller (WLC): This fabric device connects APs and wireless endpoints to the SDA fabric.
+ Intermediate nodes: These are intermediate routers or extended switches that do not provide any sort of SD-Access fabric role other than underlay services.

NEW QUESTION 77
Which EIGRP feature allows the use of leak maps?
- A. offset-list
- B. stub
- C. address-family
- D. neighbor
Answer: B
Explanation:
If we configured an EIGRP stub router so that it only advertises connected and summary routes.
But we also want to have an exception to this rule then we can configure a leak-map. For
example:
R4(config-if)#router eigrp 1
R4(config-router)#eigrp stub
R4(config)#ip access-list standard R4_L0opback0
R4(config-std-nacl)#permit host 4.4.4.4
R4(config)#route-map R4_L0opback0_LEAKMAP
R4(config-route-map)#match ip address R4_L0opback0
R4(config)#router eigrp 1
R4(config-router)#eigrp stub leak-map R4_L0opback0_LEAKMAP
As we can see the leak-map feature goes long with 'eigrp stub' command.

NEW QUESTION 79
Which statement about Cisco Express Forwarding is true?
- A. It makes forwarding decisions by a process that is scheduled through the IOS scheduler.
- B. It uses a fast cache that is maintained in a router data plane.
- C. it maintains two tables in the data plane the FIB and adjacency table.
- D. The CPU of a router becomes directly involved with packet-switching decisions.
Answer: C
Explanation:
Explanation
Cisco Express Forwarding (CEF) provides the ability to switch packets through a device in a very quick and efficient way while also keeping the load on the router's processor low. CEF is made up of two different main components: the Forwarding Information Base (FIB) and the Adjacency Table. These are automatically updated at the same time as the routing table.
The Forwarding Information Base (FIB) contains destination reachability information as well as next hop information. This information is then used by the router to make forwarding decisions.
The FIB allows for very efficient and easy lookups. Below is an example of the FIB table:
The adjacency table is tasked with maintaining the layer 2 next-hop information for the FIB. An example of the adjacency table is shown below:
It uses a fast cache that is maintained in a router data plane' fast cache is only used when fast switching is enabled while CEF is disabled.
