Q321. Refer to the exhibit. 

Which statement about the output is true? 

A. The flow is an HTTPS connection to the router, which is initiated by 144.254.10.206. 

B. The flow is an HTTP connection to the router, which is initiated by 144.254.10.206. 

C. The flow is an HTTPS connection that is initiated by the router and that goes to 144.254.10.206. 

D. The flow is an HTTP connection that is initiated by the router and that goes to 144.254.10.206. 

Answer: A 

Explanation: 

We can see that the connection is initiated by the Source IP address shown as 144.254.10.206. We also see that the destination protocol (DstP) shows 01BB, which is in hex and translates to 443 in decimal. SSL/HTTPS uses port 443. 

Q322. What are the two requirements for BGP to install a classful network into the BGP routing table? (Choose two) 

A. The AS contains the entire classfull network. 

B. A classful network statement with a lower administrative distance is in the routing table. 

C. Auto-summary is enabled. 

D. A classful network statement with a classful mask is in the routing table. 

E. Synchronization is enabled. 

F. Synchronization is disabled. 

Answer: C,D 

Q323. Refer to the exhibit. 

If OSPF is implemented on the network, which additional configuration is needed to allow traffic from host 10.4.1.15/24 to host 10.1.2.20/24? 

A. A virtual link between router 2 and router 4 

B. A virtual link between router 3 and router 4 

C. A virtual link between router 2 and router 3 

D. The current design allows traffic between the two hosts. 

Answer: D 

Explanation: 

This specific traffic from 10.4.1.0/24 to 10.1.2.0/24 would work because this traffic crosses only over the single OSPF area of 0.0.0.1. 

However, traffic from hosts on R4 to R1 would indeed need a virtual link, since area 0.0.0.2 is not connected to the backbone area of 0.0.0.0. 

Q324. Refer to the exhibit. 

All of the routers on this network are running RIP. If you edit the R3 RIP process configuration to reduce the number of hops from R3 to R1, which statement about the configuration change is true? 

A. Configuring no passive-interface for GigabitEthernet0/0 in the R3 RIP process reduces the number of hops to R1 by 2. 

B. Configuring no passive-interface for GigabitEthernet0/0 in the R3 RIP process reduces the number of hops to R1 by 1. 

C. Configuring no passive-interface for GigabitEthernet0/1 in the R3 RIP process reduces the number of hops to R1 by 3. 

D. Configuring no passive-interface for GigabitEthernet0/1 in the R3 RIP process reduces the number of hops to R1 by 1. 

Answer: A 

Explanation: 

By changing the link from R3 to R2 to not be passive, traffic can then take the direct route from R3-R2-R1 instead of the longer path of R3-R6-R5-R4-R1, resulting in two less hops. 

Q325. Which two statements about class maps are true? (Choose two.) 

A. As many as eight DSCP values can be included in a match dscp statement. 

B. The default parameter on a class map with more than one match command is match-any. 

C. The match class command can nest a class map within another class map. 

D. A policy map can be used to designate a protocol within a class map. 

Answer: A,C 

Explanation: 

Answer A. 

Router(config-cmap)# match [ip] dscp dscp-value [dscp-value dscp-value dscp-value 

dscp-value dscp-value dscp-value dscp-value] 

(Optional) Identifies a specific IP differentiated service code point (DSCP) value as a match criterion. Up to eight DSCP values can be included in one match statement. 

Answer C. 

Router config-cmap)# match class-map class-name (Optional) Specifies the name of a traffic class to be used as a matching criterion (for nesting traffic class [nested class maps] within one another).

Q326. Refer to the exhibit. 

A PE router is configured with a policy map that contains the policer shown. The policy map is configured in the inbound direction of an interface facing a CE router. If the PE router 

receives 12Mb/s of traffic with the CoS value set to 7 on a 100-Mb/s interface from the CE router, what value of MPLS EXP is set when this traffic goes through the policer shown? 

A. 0 

B. 6 

C. 7 

D. 8 

Answer: B 

Explanation: 

Here, the policer is set where the conforming traffic is set to 10 percent of the 100 Mbps interface, so anything more than 10 Mbps will be placed into the exceeding traffic class, the traffic EXP value will be changed from 7 to 6 per the configuration. 

Q327. Which three characteristics are shared by subinterfaces and associated EVNs? (Choose three.) 

A. IP address 

B. routing table 

C. forwarding table 

D. access control lists 

E. NetFlow configuration 

Answer: A,B,C 

Q328. DRAG DROP 

Drag and drop each policy command on the left to the function it performs on the right. 

Answer: 

Q329. Which attribute is transported over an MPLS VPN as a BGP extended community? 

A. route target 

B. route distinguisher 

C. NLRI 

D. origin 

E. local preference 

Answer: A 

Q330. Which two pieces of information does RTCP use to inform endpoint devices about the RTP flow? (Choose two.) 

A. the transmitted octet 

B. the lost packet count 

C. session control function provisioning information 

D. the CNAME for session participants 

E. the authentication method 

F. MTU size changes in the path of the flow 

Answer: A,B 

Explanation: 

RTCP transports statistics for a media connection and information such as transmitted octet and packet counts, packet loss, packet delay variation, and round-trip delay time. An application may use this information to control quality of service parameters, perhaps by limiting flow, or using a different codec.
