Question 161

There is an existing network of router RI, router R, router R3, and router R4 The 4 routers are interconnected via an LN network. All 4 routers are equipped with basic oSPF. When you execute the command "displayosp" on router R2 f peer", router R2 and router R3 are discovered The status between is "2-way". So what conclusions can you draw from this output? Multiple choice questions).

Router R2 is not a DR

Router R3 is not a DR, nor is it a BDR

There is no full adjacency between router R2 and router R3

Router R4 is destined for DR

Router R2 is DR or BDR

Question 162

The following description of BGP load sharing is wrong with ?( Multiple choice question)

The AS_Path properties of the equivalent routes that form load sharing must be different.

The destination CIDR blocks are the same, and load sharing can be formed between BGP routes with different sources.

If BGP load sharing is implemented , the local device needs to configure the peer next-hop-local command to change the next hop address to its own address when issuing a route to an IBGP peer group .

IBGP routes and EBGP routes that reach the same destination in the public network can form a load sharing

If you delete a declared route entry on a BGP router, the BGP routing ring is triggered to send an Update message for route scattering, which carries the accepted mandatory attribute of the route entry that was discarded.

True

False

Question 164

The following statement about OSPF route filtering is incorrect.( Single choice questions).

In the NSSA area, filtering for external route ingestion and advertisement can be configured on ASBR or ABR

Filtering for the three types of LSAs needs to be configured on the ABR across OSPF regions

Interface-based filtering of LSAs allows all LSAs in the inbound and outbound directions except grace LSAs

Based on the link state database, when calculating routes, the fiter-policy import command is used, which only affects the route addition in the route table, and has no effect on the OSPF link state database

Question 165

Regarding the Stub region and the Totally Stub region of the OSPF protocol, the following statement is correct (multiple choice)

After modifying the original Stub area to a Totally Stub area, the number of LSAs in the LSDB of each router in the region will definitely be reduced

ASBR cannot be present in either the Stub zone or the Totally Stub zone

When you modify the original Stub area to a Totally Stub region, the number of LSAs propagating within the region will definitely decrease

If there are two ABR in the Totally Stub zone, each ABR sends an LS ID of 0000 to the router in the zone LSA

Question 166

When there are multiple rule rules for ACLs in VRP, which of the following statements is true regarding the order of matching? Single choice questions).

By default, matching is based on the principle of "depth first"

By default, matching occurs in the order in which the permit is matched first and denim later.

By default, matching is made from smallest to largest according to the Rule-ID.

There is only one matching order and cannot be modified.

Question 167

Which of the following is incorrect about HTTPS?( Multiple Choice)

HTTPS secures access to data by using SSLVPN.

If the HTTPS traffic contains a virus, the router cannot detect the virus directly using IPStechnology

When using HTTPS to access a website, the website cannot be accessed if the user's browser doesnot recognize the website's digital certificate.

HTTPS protocol uses TCP port 443 by default

Question 168

What are the differences between traffic policing and traffic shaping?

Traffic shaping is applied in the inlet direction and traffic supervision is applied in the outlet direction

For traffic shaping, the router caches excess packets until bandwidth is available again

The token bucket algorithm is used for traffic supervision, and the SPD algorithm is used for traffic shaping

For traffic policing, the usage of the buffer can be adjusted for traffic exceeding the CIR

For traffic shaping, it can be over-CIR Traffic adjustment for the usage of the buffer

Question 169

The following description of VRRP load sharing is correct?( Multiple choice questions).

When configuring priority, make sure that the same router acts as a master in the three VRRP backup groups

You can create multiple VRRP backup groups on one interface of a router . The router can act as a master for one VRRP backup group and as a backup for other VRRP backup groups

When you deploy load sharing, hosts in the same LAN are required to configure the IP addresses of different virtual routers as gateway addresses for missing provinces

VRRP load sharing requires at least two virtual routers to provide forwarding services at the same time
