NEW QUESTION # 325
A customer has several remote sites connected with their headquarters through microwave links. An engineer must propose a backup WAN solution based on these conditions:
Which backup WAN link type the engineer recommend?
Answer: B
NEW QUESTION # 326
The implementations group has been using the test bed to do a 'proof-of-concept' that requires both Client 1 and Client 2 to access the WEB Server at 209.65.200.241. After several changes to the network addressing, routing scheme, DHCP services, NTP services, layer 2 connectivity, FHRP services, and device security, a trouble ticket has been opened indicating that Client 1 cannot ping the 209.65.200.241 address.
Use the supported commands to isolated the cause of this fault and answer the following questions.
The fault condition is related to which technology?
Answer: F
Explanation:
On R1, for IPV4 authentication of OSPF the command is missing and required to configure------ ip ospf authentication message-digest
NEW QUESTION # 327
Refer to the exhibit.
Customers report low video quality and delays when having point-to-point telepresence video calls between the two locations. An architect must optimize a design so that traffic follows the same path for egress and ingress traffic flows. Which technique optimizes the design?
Answer: C
NEW QUESTION # 328
Which two functions does the control plane node provide in a Cisco SD-Access architecture? (Choose two.)
Answer: B,C
Explanation:
The Cisco SD-Access control-plane node provides the host tracking database and map-server function. SD- Access uses LISP-based control-plane behavior to separate endpoint identity from endpoint location. Fabric edge nodes register endpoints with the control-plane node, and the control-plane node maintains the endpoint- to-location database. When a fabric node needs to forward traffic to an endpoint, it queries the control-plane node so the destination endpoint can be resolved to the correct fabric location. In LISP terminology, this maps to the map-server and map-resolver role, while the SD-Access design discussion often refers to the endpoint database or host tracking database. The control-plane node does not enforce policy mapping by itself; policy is integrated with Cisco ISE and applied through scalable group policy in the fabric. It also does not function as a proxy ETR in this option set. Endpoint registration is initiated by the edge nodes, which detect local endpoints and inform the control plane. Therefore, host tracking database and map server are the correct functions. Reference topics: SD-Access control plane, LISP map server, host tracking database, EID-to- RLOC mapping.
NEW QUESTION # 329
A customer has several remote sites connected with their headquarters through microwave links.
An engineer must propose a backup WAN solution based on these conditions:
- A physical WAN solution is not available for most of the sites.
- The customer has a limited budget and a short time frame for
implementation.
- The backup link will have low bandwidth requirements.
- Users will tolerate a WAN outage of up to 2 hours.
Which backup WAN link type should the engineer recommend?
Answer: C
