Cisco Implementing Cisco Enterprise Network Core Technologies (350-401 ENCOR) Sample Questions (Q350-Q355):

NEW QUESTION # 350
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
Table Description automatically generated

+ 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 # 351
Which statement describes the IP and MAC allocation requirements for virtual machines on types 1 hypervisors?

Answer: C

Explanation:
Explanation
A virtual machine (VM) is a software emulation of a physical server with an operating system.
From an application's point of view, the VM provides the look
and feel of a real physical server, including all its components, such as CPU, memory, and network interface cards (NICs).
The virtualization software that creates VMs and performs the hardware abstraction that allows multiple VMs to run concurrently is known as a hypervisor.
There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer 'Each virtual machine requires a unique IP and MAC addresses to be able to reach to other nodes' big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).


NEW QUESTION # 352

Refer to the exhibit. Which command set enables router R2 to be configured via NETCONF?

Answer: D

Explanation:
To enable router R2 to be configured via NETCONF, the necessary command set is found in Option C.
NETCONF is a network management protocol developed and standardized by the IETF. It allows for the installation, manipulation, and deletion of the configuration of network devices. The commands in Option C are designed to start the NETCONF server on the device and open the required NETCONF session over SSH, which is the standard transport for NETCONF.


NEW QUESTION # 353
Which feature allows HSRP to failover from the active route processor to the standby route processor without loss of data or path change?

Answer: D


NEW QUESTION # 354
Wireless users report frequent disconnections from the wireless network. While troubleshooting a network engineer finds that after the user a disconnect, the connection re-establishes automatically without any input required. The engineer also notices these message logs .

Which action reduces the user impact?

Answer: A

Explanation:
These message logs inform that the radio channel has
been reset (and the AP must be down briefly). With
dynamic channel assignment (DCA), the radios can
frequently switch from one channel to another but it also
makes disruption. The default DCA interval is 10 minutes,
which is matched with the time of the message logs. By
increasing the DCA interval, we can reduce the number of
times our users are disconnected for changing radio
channels.
