Cisco 350-401 - Questions & Answers

Layer 3 Routed Access--The use of a Layer 3 routed access network for the fabric provides the highest level of availability without the need to use loop avoidance protocols such as Spanning-Tree (STP), interface bundling techniques using link aggregation technologies such as EtherChannel, and Layer 2 redundancy technologies like StackWise Virtual (SVL), Virtual Switching System (VSS), or Nexus Virtual Port-Channels (vPCs).

172.16.50.5 in hex is We will have the answer from this paragraph: "TLV values for the Option 43 suboption: Type + Length + Value. Type is always the suboption code 0xf1. Length is the number of controller management IP addresses times 4 in hex. Value is the IP address of the controller listed sequentially in hex. For example, suppose there are two controllers with management interface IP addresses, 192.168.10.5 and 192.168.10.20. The type is 0xf1. The length is 2 * 4 = 8 = 0x08. The IP addresses translates to c0a80a05 (192.168.10.5) and c0a80a14 (192.168.10.20). When the string is assembled, it yields f108c0a80a05c0a80a14. The Cisco IOS IT Certification Guaranteed, The Easy Way! 81command that is added to the DHCP scope is option 43 hex f108c0a80a05c0a80a14."

Therefore in this question the option 43 in hex should be "F104.AC10.3205 (the management IP address of 172.16.50.5 in hex is AC.10.32.05).

CoPP protects the route processor on network devices by treating route processor resources as a separate entity with its own ingress interface (and in some implementations, egress also). CoPP is used to police traffic that is destined to the route processor of the router such as:
+ routing protocols like OSPF, EIGRP, or BGP.
+ Gateway redundancy protocols like HSRP, VRRP, or GLBP. + Network management protocols like telnet, SSH, SNMP, or RADIUS.

Therefore we must apply the CoPP to deal with SSH because it is in the management plane. CoPP must be put under "control-plane" command.

Syslog points to local router having VIP ip 10.1.1.25, and remote router in g0/0 interface having 10.1.1.1. We want latter to all routers in HSRP so we need to configure local router, hence B.
"is different to the locally configured..."

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.

The Cisco SD-WAN architecture implements two types of data policy:

Centralized data policy controls the flow of data traffic based on the source and destination addresses and ports and DSCP fields in the packet's IP header (referred to as a 5-tuple), and based on network segmentation and VPN membership.
These types of data policy are provisioned centrally, on the Cisco vSmart controller, and they affect traffic flow across the entire network.

Localized data policy controls the flow of data traffic into and out of interfaces and interface queues on a Cisco vEdge device. This type of data policy is provisioned locally using access lists. It allows you to classify traffic and map different classes to different queues. It also allows you to mirror traffic and to police the rate at which data traffic is transmitted and received.

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. A 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).
